add CHANGES entry for additional abuse logging
     1 MoinMoin Version History
     2 ========================
     3 
     4 Please note: Starting from the MoinMoin version you used previously, you
     5 should read all more recent entries (or at least everything marked with HINT).
     6 
     7 This release has known bugs (see MoinMoin:MoinMoinBugs), but we think it is
     8 already better than the previous stable release. Our release policy is not
     9 trying to make a "perfect release" (as that release might NEVER get released),
    10 but to make progress and don't delay releases too much.
    11 
    12 Known main issues:
    13 
    14   * The GUI WYSIWYG editor has still some issues and limitations.
    15     If you can't live with those, you can simply switch it off by using:
    16     editor_force = True
    17     editor_default = 'text'  # internal default, just for completeness
    18 
    19 Version 1.9.8:
    20   SECURITY HINT: make sure you have allow_xslt = False (or just do not use
    21   allow_xslt at all in your wiki configs, False is the internal default).
    22   Allowing XSLT/4suite is very dangerous, see HelpOnConfiguration wiki page.
    23 
    24   HINT: Python >= 2.5 is maybe required! See docs/REQUIREMENTS for details.
    25 
    26   New features:
    27   * cfg.recovery_token_lifetime to determine how long the password recovery
    28     token will be valid, default is 12 [h]. Check this setting to be adequate
    29     before doing (global) password resets, so your users have enough time to
    30     react before the toke times out!
    31   * cfg.log_events_format can be used to configure the format of the records
    32     written to <data_dir>/event-log:
    33     0 = dot not create event-log entries (saves disk space, disk I/O)
    34     1 = standard (like in moin <= 1.9.7) [default]
    35     2 = extended (add infos about username, wikiname, url)
    36   * add a tool to output the contents of the event-log to CSV:
    37     moin export eventlog --file=output.csv
    38     Output encoding is utf-8, columns are in this order:
    39     time, event, username, ip, wikiname, pagename, url, referrer, ua
    40     time: UNIX timestamp (float)
    41   * reimplement cfg.log_timing - if True, emits INFO level log output like:
    42     "timing: <REMOTE_ADDR> <URL> <REFERRER> <TIME> <SLOWNESS-INDICATOR>"
    43     TIME is in seconds, the slowness indicator is "." for sub-second requests
    44     or N times "!" for requests taking N seconds (so you easily can grep for
    45     slow stuff).
    46   * add "abuse" logging. this will log every attempt to login (successful ones
    47     as well as unsuccessful ones). abuse logging is configured via the logging
    48     configuration, see example in wiki/config/logging/abuse.
    49     Currently, abuse logging is implemented for:
    50     * authentication system
    51       * "moin" auth
    52       * "given" auth
    53       * setuid (when superuser switches to another user)
    54     * new user creation
    55     * some security/ACL violations (xmlrpc and perhaps others not implemented)
    56   * surge protection for authentication (currently only for MoinAuth):
    57     a) surge protect by IP
    58        This covers the case someone is trying to authenticate way too
    59        often - we don't look at the username here, just at the remote IP
    60        address. If surge protection kicks in for some specific IP, that IP
    61        won't be able to try to authenticate any more until surge_lockout_time
    62        is over.
    63        Note: be careful with users behind proxies or NAT routers - these are
    64              common and legitimate cases with (potentially lots of)
    65              authentication requests coming from same IP.
    66              if it is a trusted proxy, you can configure moin so it sees the
    67              real remote IP address (not just the proxy's address).
    68     b) surge protect by name
    69        This covers the case someone is trying to authenticate for a
    70        specific user name way too often (e.g. when someone tries to attack the
    71        wiki admin's account). We don't look at the IP here, just at the user
    72        name. If surge protection kicks in for some specific user name, that user
    73        name will not be able to try to authenticate any more until
    74        surge_lockout_time is over.
    75        Note: this even covers widely distributed attacks against a user, but
    76              you should only enable this if you are aware that the "real" user
    77              also won't be able to authenticate while surge protection is active
    78              (at least not using the account for that specific username).
    79              Thus, there is some denial-of-service danger with this if the
    80              attacker can guess or find your valid user names (which isn't too
    81              difficult if your wiki is publicly readable).
    82              This is bad, but technically hard to avoid.
    83     Configuration (allowing 10 authentication attempts per hour):
    84         surge_action_limits = {
    85             # ...
    86             'auth-ip': (10, 3600),  # same remote ip (any name)
    87             'auth-name': (10, 3600),  # same name (any remote ip)
    88          }
    89   * backlinks performance tuning: the pagename in the theme has historically
    90     been used to trigger a "linkto:ThisPage" search. While this is a nice
    91     feature for human users of the wiki (esp. on category pages), it has one
    92     big issue: as it is a normal link, stupid crawlers (ignoring "nofollow")
    93     follow it and cause a lot of unneccessary load.
    94 
    95     What moin shows in that "backlinks" place can now be configured in your
    96     wiki config:
    97 
    98     # always render the backlink as in moin < 1.9.8 (bad bots causing high load!):
    99     backlink_method = lambda cfg, req: 'backlink'
   100 
   101     # always render a simple link to same page, as in moin 2.0:
   102     backlink_method = lambda cfg, req: 'pagelink'
   103 
   104     # logged-in users get the backlink, anon users/bots get a pagelink (default):
   105     backlink_method = lambda cfg, req: 'backlink' if req.user.valid else 'pagelink'
   106 
   107     # logged-in users get the backlink, anon users/bots get simple text:
   108     backlink_method = lambda cfg, req: 'backlink' if req.user.valid else 'text'
   109   * AbandonedPages macro: check user agent to reduce load caused by bots
   110   * RSS feed: check for bots and rather give them empty results than waste a
   111     lot of time with them
   112   * ldap_auth: support placeholders for basedn also, e.g. you could use:
   113     base_dn='uid=%(username)s,ou=people,dc=company,dc=com'
   114   * move or delete multiple attachments (see checkboxes and buttons on the
   115     AttachFile view). Be careful: in the same way as you could delete a single
   116     attachment with one click, you can now delete all attachments of a page
   117     with one click (we don't ask for a 2nd confirmation, so think first).
   118   * mailimport: use relative attachment link markup instead of absolute links,
   119     enables some page renaming operations without needing to edit the markup.
   120   * better caching and lookup optimizations for userprofile data:
   121     * name, email, jid, openids -> userid lookups
   122     * page subscriptions for notifications (as a consequence, determination of
   123       subscribers when a page is saved is much faster now, esp. for wikis with
   124       many users) - see also MoinMoinBugs/GetSubscribersSlow
   125   * Notification template strings are now configurable via cfg.mail_notify_...
   126     * page_text (this puts together the pieces for the mail body, used for all
   127       changed / deleted / renamed page mail notifications)
   128     * page_changed_subject, page_changed_intro
   129     * page_deleted_subject, page_deleted_intro
   130     * page_renamed_subject, page_renamed_intro
   131     * att_added_subject, att_added_intro
   132     * att_removed_subject, att_removed_intro
   133     * user_created_subject, user_created_intro
   134     * Best is to read HelpOnConfiguration and look at MoinMoin.config.multiconfig
   135       to see the help text and the defaults.
   136     * The defaults are chosen to be the same as the old hardcoded values, so the
   137       translations keep working.
   138     * If you overwrite the strings in your configuration moin will still try to
   139       translate your strings, but it will only find translations if you add them
   140       to the gettext catalogs, too.
   141     * Examples:
   142 
   143       a) notification mail body: you don't want the rendered diff, you don't
   144          want to link to the diff, but to the full page view on your wiki.
   145 
   146       # original (default) value
   147       mail_notify_page_text = '%(intro)s%(difflink)s\n\n%(comment)s%(diff)s'
   148       # put this in your wiki config
   149       mail_notify_page_text = '%(intro)s%(pagelink)s\n\n%(comment)s'
   150 
   151       b) notification mail subject:
   152       # original (default) value
   153       mail_notify_page_changed_subject = '[%(sitename)s] %(trivial)sUpdate of "%(pagename)s" by %(username)s'
   154 
   155       c) notification mail intro:
   156       # original (default) value
   157       mail_notify_page_changed_intro = \
   158           ("Dear Wiki user,\n\n"
   159            'You have subscribed to a wiki page or wiki category on "%(sitename)s" for change notification.\n\n'
   160            'The "%(pagename)s" page has been changed by %(editor)s:\n')
   161 
   162       Note: if you change "*_page_changed_*", you likely also want to change
   163       "*_page_deleted_*" and "*_page_renamed_*", maybe even "*_att_added_*"
   164       and "*_att_removed_*".
   165 
   166   Fixes:
   167   * security fix: XSS in useragents stats
   168   * do not create empty pagedirs (with empty edit-log). To clean up all the
   169     trash pagedirs, use moin ... maint cleanpage.
   170   * page rename/delete, attachment add/remove email notifications work now
   171     (somehow we had an event for this, but no code handling it)
   172   * AttachFile do=get and do=view: send 404 status if file does not exist
   173   * link rel="Alternate" links: rather use page.url than request.href, so
   174     url_prefix_action gets used for the (print and raw) action URLs
   175   * fixed wrong detection of UI language from accept-language header for not
   176     logged-in users if the language identifier there was (partially) uppercase.
   177   * fix Python 2.7.4/5 compatibility issue with rss_rc action using handler._out
   178   * fix "moin import wikipage" timestamp confusion
   179   * use 302 http status for #redirect as some clients cache 301 redirects, but
   180     the #redirect might get changed or removed later (so it should not be
   181     cached and we also can't really say it is permanent)
   182   * fix crash when macro names contain non-ascii chars
   183   * CopyPage action: fix NameError exception when TextCha was answered wrong
   184   * docbook formatter: fix image URL generation, avoid script name duplication
   185   * fix caching scope of name2id/openid2id caches (was: "wiki", now:
   186     "userdir"). this is relevant for shared user_dir configurations.
   187   * moin maint cleancache: cleans up openid2id cache now also
   188   * "userdir" caching scope used for userid lookup caches (the previously used
   189     name2id cache with "wiki" caching scope could have outdated data if you
   190     share the user_dir between multiple wikis)
   191 
   192   Other changes:
   193   * rss_rc action (RSS feed) is now much faster / much less resource consuming
   194     when requested for a specific single page. As we have a link to this in
   195     every page's html output, this likely also lightens the load caused by bots
   196     and search engine crawlers.
   197   * tuned editlog.news() - only open/read log if there is new stuff in it after
   198     last read position
   199   * improve python2.5 compatibility (with_statement)
   200   * add bingbot to ua_spiders
   201   * upgraded bundled werkzeug to 0.8.3
   202   * upgraded bundled passlib to 1.6.2
   203   * upgraded bundled pygments to 1.6
   204 
   205 
   206 Version 1.9.7:
   207   New features:
   208   * passlib support - enhanced password hash security. Special thanks go to
   209     the Python Software Foundation (PSF) for sponsoring development of this!
   210 
   211     Docs for passlib: http://packages.python.org/passlib/
   212 
   213     If cfg.passlib_support is True (default), we try to import passlib and set
   214     it up using the configuration given in cfg.passlib_crypt_context (default
   215     is to use sha512_crypt with default configuration from passlib).
   216 
   217     The passlib docs recommend 3 hashing schemes that have good security, but
   218     some of them have additional requirements:
   219     sha512_crypt needs passlib >= 1.3.0, no other requirements.
   220     pbkdf2_sha512 needs passlib >= 1.4.0, no other requirements.
   221     bcrypt has additional binary/compiled package requirements, please refer to
   222     the passlib docs.
   223 
   224     cfg.password_scheme should be '{PASSLIB}' (default) to tell that passlib is
   225     wanted for new password hash creation and also for upgrading existing
   226     password hashes.
   227 
   228     For the moin code as distributed in our download release archive, passlib
   229     support should just work, as we have passlib 1.6.1 bundled with MoinMoin
   230     as MoinMoin/support/passlib. If you use some other moin package, please
   231     first check if you have moin AND passlib installed (and also find out the
   232     passlib version you have installed).
   233 
   234     If you do NOT want to (not recommended!) or can't use (still using python
   235     2.4?) passlib, you can disable it your wiki config:
   236 
   237         passlib_support = False  # do not import passlib
   238         password_scheme = '{SSHA}'  # use best builtin hash (like moin < 1.9.7)
   239 
   240     Please note that after you have used moin with passlib support and have user
   241     profiles with passlib hashes, you can't just switch off passlib support,
   242     because if you did, moin would not be able to log in users with passlib
   243     password hashes. Password recovery would still work, though.
   244 
   245     password_scheme always gives the password scheme that is wanted for new or
   246     recomputed password hashes. The code is able to upgrade and downgrade hashes
   247     at login time and also when setting / resetting passwords for one or all
   248     users (via the wiki web interface or via moin account resetpw script
   249     command).
   250 
   251     So, if you want that everybody uses strong, passlib-created hashes,
   252     resetting the passwords for all users is strongly recommended:
   253     First have passlib support switched on (it is on by default), use
   254     password_scheme = '{PASSLIB}' (also default), then reset all passwords.
   255 
   256     Same procedure can be used to go back to weaker builtin hashes (not
   257     recommended): First switch off passlib support, use password_scheme =
   258     '{SSHA}', then reset all passwords.
   259 
   260     Wiki farm admins sharing the same user_dir between multiple wikis must use
   261     consistent password hashing / passlib configuration settings for all wikis
   262     sharing the same user_dir. Using the builtin defaults or doing the
   263     configuration in farmconfig.py is recommended.
   264 
   265     Admins are advised to read the passlib docs (especially when experiencing
   266     too slow logins or when running old passlib versions which may not have
   267     appropriate defaults for nowadays):
   268     http://packages.python.org/passlib/new_app_quickstart.html#choosing-a-hash
   269     http://packages.python.org/passlib/password_hash_api.html#choosing-the-right-rounds-value
   270 
   271   * Password mass reset/invalidation support, see docs/resetpw/.
   272     This is useful to make sure everybody sets a new password and moin computes
   273     the password hash using the current configuration.
   274 
   275   * Customizable default password checker:
   276     Moin's default password checker used and still uses min_length=6 (minimum pw
   277     length) and min_different=4 (minimum count of different chars in the password).
   278     If you feel that you need to require better passwords from your users, you
   279     can customize it now like that in your wiki config:
   280 
   281     password_checker = lambda cfg, request, name, pw: multiconfig._default_password_checker(cfg, request, name, pw, min_length=10, min_different=7)
   282 
   283   * Removing/disabling inactive users (moin ... account inactive)
   284     Many wikis have a lot of inactive users, that never ever made a single edit.
   285     See help of the command for more details, be careful.
   286   * SystemAdmin user browser: show disabled user accounts at the bottom of
   287     the list
   288   * At startup, announce moin version and code path in log output (makes
   289     support and debugging easier).
   290   * AttachList: introduced search_term parameter (optional) for listing
   291     attachments filtered by a regular expression on their name.
   292   * sign release archive using GnuPG with the key of tw@waldmann-edv.de
   293     ID 31A6CB60 (main key ID FAF7B393)
   294 
   295   Fixes:
   296   * logging: if the logging config file can't be read, give a helpful error msg
   297   * logging: use info loglevel (not warning) for telling about using the builtin
   298     default logging config
   299   * moin script commands: warn if someone gave ... to the moin script, avoids a
   300     strange and unhelpful 'empty module name' error message
   301   * reorder html input fields in recoverpass form, to help browsers remember
   302     the user name and password (not erroneously the recovery token and password)
   303   * don't try to send password recovery email to user if email address in
   304     user profile is empty
   305   * cache action: fix 304 http status
   306   * rst parser: fix safe_import for level param in __import__ call of docutils 0.10
   307   * moin maint cleancache: also kill the i18n cache 'meta' pickle file
   308   * sendmail: catch unicode errors when E-Mail addr has non-ascii chars
   309   * redirect last visited: if last visited page is on same wiki, use a local
   310     redirect, do not compute via interwiki map (fixes https: usage)
   311 
   312 
   313 Version 1.9.6:
   314 
   315   Fixes:
   316   * fix remote code execution vulnerability in twikidraw/anywikidraw action
   317   * fix path traversal vulnerability in AttachFile action
   318   * fix XSS issue, escape page name in rss link
   319   * escape user- or admin-defined css url
   320   * make taintfilename more secure
   321   * use a constant time str comparison function to prevent timing attacks
   322   * Attachment handler: catch all Zip-related errors
   323 
   324 
   325 Version 1.9.5:
   326 
   327   Fixes:
   328    * Security fix: fix virtual group bug in ACL evaluation.
   329    * Avoid crash if #refresh processing instruction is used without arguments.
   330    * Fix issue with non-ASCII textchas.
   331    * Xapian indexing: remove copy.copy() that crashed on Windows/IIS/isapi-wsgi
   332      after page save.
   333    * Fix dictionary file reading crash under Windows.
   334    * Work around crash of AdvancedSearch macro rendering caused by non-ascii
   335      mimetypes.types_map entries.
   336    * Added migration script for moin 1.8.9.
   337    * rss_rc: Fix diffs added in RSS with diffs=1 (now they correspond to item
   338      listed in feed and not just last page diffs). Links generated with ddiffs=1
   339      also fixed.
   340    * rss_rc: fix double escaping issue.
   341    * rss_rc: respect show_names configuration option.
   342    * rss_rc: proper support of rename, revert, page creation.
   343    * modern/modernized theme: fix padding/width for editor preview
   344    * group/pagelinks formatters: avoid to create unnecessary output, redirect
   345      output of send_page call with the groups formatter, it must not be written
   346      to the output stream
   347    * rst parser: fix include and macro directives
   348    * wikisync: fix unicode pagename sending for python 2.7 httplib
   349 
   350   New features:
   351    * add a comment_required config option (default: False) to require a
   352      non-empty comment when saving a page
   353    * when a save error happens, show the editor again and highlight the error
   354    * rss_rc: several new options added: lines parameter gives ability to set
   355      maximum size of diffs showed in RSS. show_att parameter gives ability
   356      to show information aboout attachment-related items in RSS. page parameter
   357      gives ability to specify set of pages for which changes RSS feed should be
   358      generated. Configuration of defaults and limits can now be done via wiki
   359      configuration mechanism.
   360    * As soon as it is now possible to provide RSS for page change history,
   361      appropriate alternate link is now added for every page (controlled by
   362      rss_show_page_history_link configuration parameter).
   363    * Search: "no_highlight:" search query option provided for suppressing
   364      highlighting search results.
   365    * Search macros: new options for FullSearch, FullSearchCached and PageList
   366      available:
   367      * highlight_titles option controls highlighting of matches in search
   368        results provided by these macros. Default value is set in
   369        search_macro_highlight_titles configuration option)
   370      * highlight_pages option controls adding of highlight URL parameter to
   371        page links (so search term is highlighted when user goes to one of
   372        these pages via provided link) in search results. Default value is set
   373        in search_macro_highlight_pages configuration option.
   374      Usage of these options is disabled (via search_macro_parse_args
   375      configuration option) by default due to behavioural changes introduced
   376      in macro parameter parsing mechanism to support them. Related to
   377      http://moinmo.in/FeatureRequests/FullSearchResultsWithoutHighlight .
   378

   401    * SubProcess: make sure files are closed at the end (experimental change).
   402    * text plain formatter: fix bullet_list, see number_list.
   403    * Add some image mimetypes to MIMETYPES_MORE to fix windows issues.

   428      * {DES} (Unix crypt(3))
   429      * {MD5} (MD5-based crypt())
   430      * {APR1} (Apache .htpasswd). 
   431    * Experimental queued indexing support to work around memory leak - use it like this:
   432      # put all pages into indexer queue:
   433      python MoinMoin/script/moin.py index build --mode=makequeue
   434      # take <count> pages out of the indexer queue and index them,
   435      # you need to repeat the following line respective to the total amount of pages
   436      # in your wiki (doing more indexer calls does no harm, doing less means an
   437      # incomplete index):
   438      python MoinMoin/script/moin.py index build --mode=buildnewindexqueued --count=500
   439      python MoinMoin/script/moin.py index build --mode=buildnewindexqueued --count=500
   440      python MoinMoin/script/moin.py index build --mode=buildnewindexqueued --count=500
   441      # ...
   442      # switch to new index:
   443      python MoinMoin/script/moin.py index build --mode=usenewindex 
   444 
   445   Other changes:

   449    * Use logging.traceback to get more information if a indexing filter crashes.
   450    * u200b is not considered a space any more in unicode 4.0.1.
   451    * Improve textcha security, use some crypto and timing to make cheating
   452      harder - use cfg.textchas_expiry_time = 600 (default, seconds) to set the
   453      time a textcha is valid.
   454    * Upgraded bundled werkzeug to 0.8.1, pygments to 1.4, flup to repo tip.
   455 
   456 
   457 Version 1.9.3:
   458   Fixes:
   459   * Fix XSS in Despam action (CVE-2010-0828).
   460   * Fix XSS issues (see MoinMoinBugs/1.9.2UnescapedInputForThemeAddMsg):
   461     * by escaping template name in messages
   462     * by fixing other places that had similar issues
   463   * Make moin compatible to werkzeug 0.5 .. 0.6.2 (1.9.2 had issues
   464     with xmlrpc when used with werkzeug 0.6.x).
   465   * MoinMoin.util.filesys: disable usage of dircache, deprecate dc* functions,
   466     because the dircache stdlib module can't work correctly for fast updates of
   467     directories.
   468   * rss_rc and sisterpages actions: fix Content-Type header (mimetype)
   469   * Fix associating OpenID identity with user, wasn't adapted to werkzeug yet.

   477   * Get rid of the empty line at the end of code highlights.
   478   * GUI editor: compute editor height like the text editor does.
   479   * Added help texts for: standalone server and moin migration.
   480   * script.maint.cleancache: clean also i18n cache files
   481   * Improved formatter.text_plain, see FeatureRequests/TextPlainFormatterRewrite
   482     (fixes many issues of this formatter).
   483   * text_html_text_moin_wiki: fixed index error for width="", see also:
   484     MoinMoinBugs/GUI_convertor_list_index_out_of_range
   485   * xmlrpc: disable editor backup for putPage, renamePage and revertPage
   486     because if pages get uploaded by xmlrpc then the draft cache file can
   487     rapidly increase in size, causing high memory usage because it needs to
   488     get loaded into memory for updating/processing.
   489   * Emit Content-Type header (with charset) for SlideShow action and many other
   490     actions that just call send_title().
   491   * ActionBase: better compatibility to moin 1.8, use request.values by
   492     default, optionally use request.form data only
   493 
   494   New features:
   495   * RenamePage action: added ability to create redirect pages when renaming
   496     (turned off by default, see show_rename_redirect config option).
   497   * formatter/text_html: Added line number links to code blocks.
   498   * diff action:
   499     * Fixed whitespace in generated (html) diff view table so white-space: pre
   500       can be used (and whitespace in diffs preserved).
   501     * Added links to first/last revision.
   502   * MoinMoin.widget.browser: introduced feature for sorting tables, see:
   503     http://moinmo.in/FeatureRequests/SortableTables
   504   * SystemAdmin user and attachment browsers: sorting feature used there now
   505   * Scrolling the text editor to the double clicked line.
   506   * Enable double-click-editing by default.
   507   * WikiConfigHelp macro: make heading and description display optional,
   508     heading level as a parameter (default 2)
   509   * If edit ticket check fails, send the editor with the current content.
   510   * moin import wikipage - use this script to import local files as a wiki page
   511 
   512   Other changes:
   513   * upgraded pygments from 1.2.2 to 1.3.1
   514   * upgraded FCKeditor from 2.6.4.1 to 2.6.6
   515   * added configuration snippet for ldap authentication against 2 servers
   516   * improved script help output
   517 
   518 Version 1.9.2:
   519   Fixes:
   520   * Fixed CVE-2010-0668: major security issues were discovered in misc. parts
   521     of moin.
   522     HINT: if you have removed superuser configuration to workaround the issue
   523     (following our security advisory), you may re-add it after installing this
   524     moin release. If you don't need superuser capabilities often, it might be
   525     wise to not have superusers configured all the time, though.
   526   * Fixed CVE-2010-0669: potential security issue due to incomplete user profile
   527     input sanitizing.
   528   * Improved package security: cfg.packagepages_actions_excluded excludes
   529     unsafe or otherwise questionable package actions by default now.
   530   * wiki parser: fixed transclusion of (e.g. video) attachments from other
   531     pages.
   532   * Fixed edit locking for non-logged in editors and cfg.log_remote_addr=False.
   533   * mailimport: fix missing wikiutil import for normalize_pagename
   534   * SubProcess: fix "timeout" AttributeError
   535   * "standalone" wikiserver.py: fixed calling non-existing os.getuid on win32
   536   * HTTPAuth deprecation warning moved from class level to __init__
   537   * Fixed MoinMoinBugs/1.9DiffActionThrowsException.
   538   * Fixed misc. session related problems, avoid unneccessary session file
   539     updates.
   540   * Fix/improve rename-related problems on Win32 (depending on Windows version).
   541   * Fixed spider / user agent detection.
   542   * Make sure to use language_default when language_ignore_browser is set.
   543   * diff action: fix for case when user can't revert page.
   544   * Fix trail size (was off by one).
   545   * Updated bundled flup middleware (upstream repo checkout), avoids
   546     socket.fromfd AttributeError on win32 if cgi is forced, gives helpful
   547     exception msg.
   548   * wikiutil: Fixed required_arg handling (no exception when trying to raise
   549     exception that choice is wrong).
   550   * Do not use MoinMoin.support.* to import 3rd party code, give dist packages
   551     a chance.
   552   * wikiutil.clean_input: avoid crash if it gets str type
   553   * request: fixed for werkzeug 0.6 and 0.5.1 compatibility. Please note that
   554     we didn't do much testing with 0.6 yet. So, if you use 0.6, please do some
   555     testing and provide feedback to us.
   556   * AttachFile._build_filelist: verifies readonly flag for unzip file link
   557   * attachUrl: fix wrongly generated tickets (e.g. for AttachList macro)
   558   * http headers: fix duplicated http headers (e.g. content-type)
   559 
   560   New features:
   561   * info action: added pagination ability to revision history viewer.
   562     Use cfg.history_paging = True [default] / False to enable/disable it.
   563   * ldap_login auth: add report_invalid_credentials param to control wrong
   564     credentials error message (this is typically used when using multiple
   565     ldap authenticators).
   566   * Add RenderAsDocbook to actions_excluded if we have no python-xml.
   567   * Upgraded pygments to 1.2.2 (some fixes, some new lexers).
   568   * Text editor: if edit_rows==0 (user profile or config), we dynamically size
   569     the text editor height. This avoids double sliders for the editor page
   570     in most cases.
   571 
   572   Other changes:
   573   * New docs/REQUIREMENTS.
   574   * Added a less magic cgi/fcgi driver (moin.fcgi), added fixer middleware
   575     for apache2/win32 to it.
   576 
   577 
   578 Version 1.9.1:
   579   Bug fixes:
   580   * Fixed CVE-2010-0667: sys.argv security issue.
   581   * Fixed FileSessionService - use session_dir from CURRENT request.cfg (it
   582     mixed up session_dirs in farm setups).
   583     HINT: if you added the hotfix to your wikiconfig, please remove it now.
   584   * Fixed creation of lots of session files (if anon session were enabled and
   585     user agent did not support cookies).
   586   * Fixed session file storage for a non-ascii base path.
   587   * Fixed session cookie confusion for nested URL paths (like path=/ and
   588     path=/mywiki - for more info, see also "New features").
   589   * Handle cookie_lifetime / anonymous_session_lifetime upgrade issue
   590     gracefully: emit errors/warnings to log, use old settings to create
   591     cfg.cookie_lifetime as expected by moin 1.9.
   592   * flup based frontends: fixed SCGI and AJP (didn't work).
   593   * farmconfig example: remove wrong comment, add sample http/https entry.
   594   * Fixed password reset url (email content needs full URL).
   595   * Page: fixed adding of page contents (only data added now, without metadata) -
   596     fixes MoinMoinBugs/DeprecatedPageInclusionErrornousPageInstructionsProcessing
   597   * xmlrpc:
   598     * Process attachname in get/putAttachment similarly.
   599     * revertPage: convert pagename to internal representation.
   600     * Fixed auth calls used by jabberbot (needs more work).
   601   * Added missing config.umask support code (setting was not used), fixed
   602     config.umask usage for page packages.
   603   * Fixed browser language detection.
   604   * Fixed language pack generation/installation for pt-br, zh, zh-tw.
   605   * Fixed caching of formatted msgs, see MoinMoinBugs/1.9EditPageHelpLinksBroken.
   606   * Fixed usage of i18n.wikiLanguages() on class level (moved to method), failed
   607     when tools import the module (e.g. pydoc -k foo).
   608   * highlight parser:
   609     * fixed caching issue for "toggle line numbers" link.
   610     * added missing support for console/bash session
   611   * Fixed precedence of parsers: more special parsers now have precedence
   612     before moin falls back to using the HighlightParser (syntax highlighting).
   613   * Added extensions to the rst, moin and creole parser (example.rst, example.moin and
   614     example.creole attachments are rendered now when viewed).
   615   * Fixed MoinMoinBugs/LineNumberSpansForProcessInstructionsMissed for
   616     moin_wiki, highlight and plain parser.
   617   * Fixed MoinMoinBugs/LineNumberAnchorsInPreformattedText for highlight and
   618     plain parser.
   619   * Fixed MoinMoinBugs/TableOfContentsBrokenForIncludedPages.
   620   * Exception raised on calling add_msg() after send_title(), which leads to 
   621     Internal Server Error on calling several actions (diff, preview) for 
   622     deprecated pages, is replaced with warning and call stack information in 
   623     the log.
   624   * AttachFile.move_file: send events (so e.g. xapian index update happens)
   625   * SubProcess: fixed win32-specific parts, fixed imports (fixes calling of
   626     external xapian index filters)
   627   * Fixed auth methods that use redirects (like OpenID).
   628   * OpenID client:
   629     * Add setting cfg.openidrp_allowed_op, default is [].
   630     * Fixed logging in with openid and associating with an existing account.
   631     * openidrp_sreg extension: handle UnknownTimeZoneError gracefully
   632   * OpenID server:
   633     * Fixed TypeError.
   634     * Fixed processing POSTed form data AND URL args.
   635 
   636   New features:
   637   * diff: Added displaying of information about revisions (editor, size, 
   638     timestamp, comment), added revision navigation.
   639   * text editor: added @TIMESTAMP@ variable for adding a raw time stamp
   640   * xmlrpc: added renamePage and deleteAttachment methods.
   641   * Accept "rel" attribute for links (moin wiki parser).
   642   * Generate session cookie names to fix cookie path confusion and enable port-
   643     based wiki farming.
   644 
   645     HINT: New setting cfg.cookie_name:
   646 
   647     None (default): use MOIN_SESSION_<PORT>_<PATH> as session cookie name. This
   648                     should work out-of-the-box for most setups.
   649 
   650     'siteidmagic': use MOIN_SESSION_<SITEID>, which is unique within a wiki farm
   651                    created by a single farmconfig (currently, cfg.siteid is just
   652                    the name of the wiki configuration module).
   653 
   654     'other_value': use MOIN_SESSION_other_value - this gives YOU control. Just
   655                    use same value to share the session between wikis and use a
   656                    different value, if you want a separate session.
   657 
   658     HINT: Please do not use cfg.cookie_path any more - it usually should not be
   659     needed any more, as we now always put path=/ into the cookie except if you
   660     explicitly configure something else (only do that if you know exactly what
   661     you're doing and if the default does not work for you).
   662 
   663     HINT: see also the HelpOnSessions page which shows some typical configs.
   664   * Store expiry into sessions, use moin maint cleansessions script to clean up.
   665     HINT: use moin ... maint cleansessions --all once after upgrading.
   666     HINT: you may want to add a cron job calling moin ... maint cleansessions
   667           to regularly cleanup expired sessions (it won't remove not expired
   668           sessions).
   669 
   670   Other changes:
   671   * Added rtsp, rtp, rtcp protocols to url_schemas.
   672   * Added more info about index building to xapian wikiconfig snippet.
   673   * Updated the wikicreole parser to version 1.1.
   674 
   675 
   676 Version 1.9.0:
   677   Note: This is a reduced CHANGES, ommitting details from rc/beta test and
   678         also less interesting minor changes and fixes. It shows changes
   679         relative to 1.8.6 release.
   680         If you want to see full detail, read it there:
   681         http://hg.moinmo.in/moin/1.9/file/b290d938be63/docs/CHANGES
   682 
   683   New features: ==============================================================
   684   * HINT: MoinMoin requires Python 2.4 now. If you only have Python 2.3 and
   685     you don't want to upgrade it, please use MoinMoin 1.8.x.
   686   * HINT: MoinMoin is now a WSGI application.
   687     Please read the new install docs about how to use it, see:
   688     http://master19.moinmo.in/InstallDocs
   689     You also have a local copy of that page as docs/INSTALL.html.
   690   * HINT: due to big changes in the request processing and the request
   691     object (related to the WSGI refactoring), many 3rd party plugins might
   692     need code updates to work with moin 1.9.
   693   * HINT: We now offer different sized sets of system/help pages and the default
   694     underlay just contains a single page: LanguageSetup. You need to be
   695     superuser, visit that page and then install the language packs you like
   696     (minimum is the essential set for English).
   697   * HINT: LanguageSetup is the default page_front_page, you need to change that
   698     after installing language packs (see above).
   699 
   700   * New modular group and dict data access, you can use group and dict 
   701     backend modules to access group and dict data stored anywhere you like.
   702     Currently we provide these backends:
   703       * WikiGroups and WikiDicts backends get data from wikipages. They work
   704         similar to old wikidicts code (but with less caching issues :).
   705       * ConfigGroups and ConfigDicts backends get data from a dictionary
   706         defined in the wiki config.
   707       * CompositeGroups and CompositeDicts compose several backends, so data
   708         may be retrieved from several sources. For example, groups may be
   709         defined in the wiki config and on wiki pages.
   710     * Using cfg.groups and cfg.dicts, you can define the backend to use to
   711       access group and dict information (default: WikiGroups / WikiDicts
   712       backend).
   713       See the wiki/config/more_samples/ directory (groups_wikiconfig_snippet
   714       and dicts_wikiconfig_snippet).
   715     * See also the new HelpOnDictionaries and HelpOnGroups pages.
   716 
   717   * Improved Xapian indexing / search:
   718     * Moin's Xapian based search code was refactored:
   719       * It is now based on the xappy library (see MoinMoin.support.xappy).
   720       * Minimum Xapian requirement is 1.0.6 now.
   721       * Outdated and unmaintained xapwrap lib was removed.
   722       * regex search with Xapian enabled also is based on the xapian index now
   723     * Safe 2-stage xapian index rebuilding:
   724       moin index build --mode=buildnewindex  # slow, concurrent
   725       <stop wiki>
   726       moin index build --mode=usenewindex  # fast
   727       <start wiki>
   728     * Added wikiconfig snippet for xapian search.
   729 
   730   * Improved drawing support:
   731     * TWikiDraw:
   732       * Support code was refactored/moved to the twikidraw action.
   733       * Use drawing:example.tdraw to invoke it (drawing:example also still
   734         works for backwards compatibility)
   735       * Drawings are now stored as a single attachment foo.tdraw.
   736         We added a migration script that converts your existing drawings.
   737     * AnyWikiDraw:
   738       * Java applet added, source code see contrib/.
   739       * Support code for it is in anywikidraw action.
   740       * Use drawing:example.adraw to invoke it.
   741       * Drawings are stored in a similar way as foo.adraw.
   742     * cfg.extensions_mapping added for mapping of attachment file extensions
   743       to actions (currently used for anywikidraw/twikidraw action)
   744 
   745   * Themes / static files related:
   746     * Added modernized_cms theme (hides most wiki widgets from modernized if the
   747       user is not logged in).
   748     * Static file serving built-in (moved wiki/htdocs to MoinMoin/web/static/htdocs).
   749       MoinMoin.web.static has a static file serving wrapper that uses the files
   750       from htdocs subdirectory by default (docs=True).
   751       You can also give another path or switch off creation of that static wrapper.
   752       See the docstring of the static package for details.
   753     * Theme packages: do_copythemefile now copies theme files to
   754       MoinMoin/web/static/htdocs.
   755 
   756   * Syntax highlighting is based on the pygments library now, it does this for
   757     LOTS of stuff (programming languages, config files, ...) - use it like this:
   758     {{{#!highlight xxx
   759     ...
   760     }}}
   761     xxx is any of the markups pygments supports (see HelpOnParsers).
   762     Note: we still have some (deprecated) small wrappers around pygments,
   763     so the old syntax #!python/pascal/cplusplus/... still works.
   764 
   765   * Authentication improvements:
   766     * HTTP auth related (see also HelpOnAuthentication):
   767       * HTTPAuthMoin: http basic auth done by moin
   768       * HINT: auth.http.HTTPAuth is now auth.GivenAuth
   769         This was badly named from the beginning as for most servers, it just
   770         looked at REMOTE_USER environment variable and relied on the server
   771         doing the authentication (could be http basic auth or any other auth).
   772     * LDAP/AD auth: new name_callback param to create a custom wiki username (not
   773       the ldap login username)
   774     * OpenID auth:
   775       * Support for Simple Registration (SREG) extension.
   776         Basic profile fields can be copied from OpenID provider when logging in.
   777       * Support for Teams extension.
   778       * Ability to accept logins from specific OpenID providers.
   779         Login form changes based on configuration for better usability:
   780         * 0 providers: normal text input box for OpenID URL
   781         * 1 provider: hidden field, automatic form submission with JavaScript
   782         * 2+ providers: select field, uses directed identity
   783 
   784   * Sessions / cookies:
   785     * HINT: cfg.cookie_lifetime is now a tuple (anon, loggedin), giving the
   786       lifetime of the cookie in hours, accepting floats, for anon sessions and
   787       logged-in sessions. Default is (0, 12). 0 means not to use a session
   788       cookie (== not to establish a session) and makes only sense for anon users.
   789     * cfg.cookie_httponly is new and defaults to False. Please note that if you
   790       set it to True, TWikiDraw and similar stuff won't be able to use the session
   791       cookie. Thus, if your wiki page doesn't allow writing for everybody, saving
   792       a drawing will fail, because there is no session (== no logged in user) for
   793       the TWikiDraw applet's saving POSTs.
   794 
   795   * Macros:
   796     * WikiConfigHelp: added section keyword for selecting a subset of the
   797       description, e.g. <<WikiConfigHelp(section="xapian")>>
   798     * HighlighterList: show Pygments syntax highlighters (see HelpOnParsers)
   799 
   800   * Actions:
   801     * SlideShow action added (please use the "modernized" theme [default])
   802     * raw action mimetype support: ...?action=raw&mimetype=text/css
   803     * PackagePages: create package file on-the-fly in memory and send it to the
   804       client (do NOT create package.zip attachment)
   805 
   806   * Improved logging / debugging / developer support:
   807     * Main exception handler: include request url in log output.
   808     * Environment variable MOIN_DEBUGGER=off/web/external (default is "off").
   809     * Handle wikiserverconfig(_local) in the same way as wikiconfig(_local).
   810 
   811   * GUI editor: improved attachment dialog
   812 
   813   * "moin ... account homepage" script to create user homepages.
   814 
   815 
   816   Removed features: ==========================================================
   817   * Removed cfg.traceback_* settings (use logging configuration)

   821 
   822 
   823   Bug fixes: =================================================================
   824   * Xapian indexing:
   825     * Rely on xapian's locking (remove moin's additional and sometimes broken
   826       locking, that blocked index-rebuilds or updates sometimes).
   827     * Removed indexer threading.
   828     * Fixed (reimplemented) indexer queue.
   829     * Less disruptive xapian index rebuild.
   830   * AdvancedSearch: example didn't work, fixed
   831 
   832   * With the groups/dicts code rewrite, we fixed the caching problems that the
   833     old code (< 1.9) sometimes had.
   834 
   835   * Actions:
   836     * Abort RenamePage if renaming of main page fails (do not try to rename
   837       subpages).
   838     * AttachFile do=view: quote filename and pagename params for EmbedObject
   839       macro call
   840     * unsubscribe action: add msg types so icons get displayed
   841 
   842   * Parsers:
   843     * fixed MoinMoinBugs/LineNumbersWorkingBuggyWithHighlightParser
   844 
   845   * GUI editor: roundtripping works now for .pdf/doc/... attachment transclusion
   846 
   847   * AttachFile: added remove_attachment() and FileRemovedEvent (mail and xapian
   848     support, no jabber support yet).
   849 
   850   * Fix makeForbidden403() calls - is makeForbidden(403, ...) now.
   851   * sendmail: add more debug logging, check for empty recipients list
   852   * Fix MoinMoinBugs/MissingPageShouldn'tOfferToCreatePageForReadonlyUsers
   853   * Fix MoinMoinBugs/1.6XmlRpcPutPagePagenameEscape
   854   * Bug with "language:en" was fixed for the Moin search. Now language:
   855     behaves like described on HelpOnSearching.
   856   * Fixed MoinMoinBugs/DeprecatedIsNotRespected (search ranking, WantedPages).
   857   * OpenID: always return error messages with CancelLogin if OpenID process fails.
   858   * suid: simplify and fix, bigger selection box
   859 
   860   * patch werkzeug 0.5.1 to catch OverFlowError and ValueError so it doesn't
   861     crash when receiving invalid If-modified-since header from client.
   862 
   863 
   864   Other changes: =============================================================
   865   * 'modernized' theme:
   866     * use it by default (1.8 used 'modern')
   867     * move title_with_separators() from Modernized theme to ThemeBase
   868     * add a span with "pagepath" class to title_with_separators
   869   * add the sidebar() method from Mandarin and Gugiel themes to ThemeBase
   870   * updated flup to 1.0.2+ ( http://hg.saddi.com/flup-server/rev/6ea1ffac1bcb )
   871   * updated pygments to 1.1.1+ ( http://dev.pocoo.org/hg/pygments-main/rev/948f8885af16 )
   872   * updated parsedatetime to 0.8.7
   873   * increase surge protection limits for AttachFile to avoid trouble with image galleries
   874   * HINT: simplify wikiserver configuration by using same names as werkzeug's
   875     run_simple() call.
   876   * Removed moin account check's --lastsaved option, it is default now
   877     (checking last use with trail file did not work in 1.9 anyway).
   878   * ImageLink page has been killed (ImageLink macro is gone since 1.6.1).
   879   * Allowed disabling of timezone and language user prefs if they are
   880     part of the user's login fields (i.e. OpenID SREG).
   881   * Added option to disable local registration links and direct user
   882     to registration page at an OpenID provider instead.
   883 
   884   Developer notes: ===========================================================
   885   * groups and dicts API changes:
   886     * request.groups and request.dicts provide access to groups and dicts.
   887     * MoinMoin.wikidicts is gone, please use MoinMoin.datastruct.
   888     * LazyGroup and LazyGroupsBackend base classes for implementing backends
   889       which potentially deal with huge amounts of data (like a LDAP directory).
   890       Use MoinMoin/datastruct/backends/config_lazy_groups.py as a draft for
   891       new backends.
   892     * See http://moinmo.in/Groups2009 for more details.
   893   * i18n: new approach for defining sets of system/help pages (see i18n.strings).
   894     CheckTranslation, page packager, wikiutil.isSystemPage() use those sets.
   895   * killed deprecated macro.form attribute (didn't work as expected anyway due
   896     to WSGI refactoring) - please use macro.request.{args,form,values}
   897 
   898 
   899 Version 1.8.8:
   900   Fixes:
   901     * Fixed XSS issues (see MoinMoinBugs/1.9.2UnescapedInputForThemeAddMsg).
   902     * Fixed XSS in Despam action (CVE-2010-0828).
   903     * wikiutil.clean_input: avoid crash if it gets str type
   904     * Add RenderAsDocbook to actions_excluded if we have no python-xml
   905     * AttachFile._build_filelist: verifies readonly flag for unzip file link
   906     * attachUrl: fix wrongly generated tickets (e.g. for AttachList macro)
   907     * MoinMoin.util.filesys.dc* (dircache can't work reliably):
   908       * disable usage of dircache, deprecate dc* functions
   909       * remove all calls to filesys.dc* (dclistdir, dcdisable)
   910     * Fixed crash, see MoinMoinPatch/IncludeMacroWithDocBookFormatter
   911     * Avoid hardly recoverable crashes if #format specification is invalid
   912 
   913   New features:
   914     * auth.ldap_login: add report_invalid_credentials param to control wrong
   915       credentials error message (typically used when using multiple ldap
   916       authenticators)
   917 
   918 
   919 Version 1.8.7:
   920   Fixes:
   921   * Fixed major security issues in miscellaneous parts of moin.
   922     HINT: if you have removed superuser configuration to workaround the issue
   923     (following our security advisory), you may re-add it after installing this
   924     moin release. If you don't need superuser capabilities often, it might be
   925     wise to not have superusers configured all the time, though.
   926   * Improved package security: cfg.packagepages_actions_excluded excludes
   927     unsafe or otherwise questionable package actions by default now.
   928   * wiki parser: fixed transclusion of (e.g. video) attachments from other
   929     pages.
   930   * Fixed edit locking for non-logged in editors and cfg.log_remote_addr=False.
   931   * xmlrpc:
   932     * Process attachname in get/putAttachment similarly.
   933     * revertPage: convert pagename to internal representation.
   934   * Fixed config.umask usage for page packages.
   935   * Fixed usage of i18n.wikiLanguages() on class level (moved to method),
   936     failed when tools import the module (e.g. pydoc -k foo).
   937   * SubProcess: fixed win32-specific parts, fixed imports (fixes calling of
   938     external xapian index filters)
   939 
   940 
   941 Version 1.8.6:
   942   Bug fixes:
   943   * Xapian indexing / indexing filters:
   944     * fix deadlocks with well- and misbehaving external filters
   945     * work around indexing run crashing when encountering encoding problems
   946       with non-ascii filenames
   947     * OpenOffice/OpenDocument filters: catch UnicodeDecodeErrors (happens
   948       with password protected files)
   949   * i18n: check if languages is not initialized yet, don't crash
   950   * http_redirect: use 301 redirect for some cases
   951   * do not use httponly session cookies, makes trouble with twikidraw and ACLs
   952   * GetText2 macro: fix for named placeholder
   953   * Fix SHA -> SSHA password hash upgrade for old user profiles.
   954   * abort RenamePage if renaming of main page fails (do not try to rename
   955     subpages)
   956 
   957   New features:
   958   * search: improve search result ordering
   959   * add MS Powerpoint indexing filter (needs catppt from catdoc package)
   960   * migration scripts: make finding damaged edit-log entries easier
   961   * SubscribeUser action: support username regexes and unsubscribing.
   962     Usage (enter this into the input form field you get after invoking
   963     SubscribeUser action from the "More Actions" menu:
   964     [+|-][re:]username[,username,...] 
   965 
   966     +username: subscribes user <username> (+ is optional/default)
   967     -username: unsubscribes user <username>
   968     +re:username_re: subscribes users who match <username_re> regex.
   969     -re:username_re: unsubscribes users who match <username_re> regex.
   970 
   971

   976     * PDF embedding: fix html, works better with PDF browser plugins now.
   977     * Fix typo in rightsidebar CSS.
   978     * Action revert: avoids reverting to a deleted current revision.

   980     * Add a Auto-Submitted: auto-generated header to generated mails.
   981     * Include comment in email notifies.
   982     * mailimport: fix endless looping while trying to import a forwarded mail.
   983     * fuid: keep same fake_mtime for intervals of max_staleness duration.
   984     * Fixes a bug with empty list items in the GUI editor.
   985     * Improve filesys.rename compatibility code (win32).
   986     * Fix locking for CacheEntry.
   987     * Xapian indexing: catch exception when a bad zip file is encountered.
   988     * openidrp / botbouncer: fix param count for CancelLogin().
   989 
   990   New features:
   991     * Added CAS authentication.
   992     * Added httponly cookie support and use it for session cookie.
   993 
   994   Other changes:
   995     * HTTP auth: added debug logging.
   996     * Minor LDAP auth improvements.

  1001     * Add gopher and apt protocols to url_schemas.
  1002     * Add .csv, .flv, .swf to MIMETYPES_MORE.
  1003 
  1004 
  1005 Version 1.8.4:
  1006   Bug fixes:
  1007     * ACL security: fix bug in hierarchical ACL processing, more restrictive
  1008       sub page ACLs did not work if the current user name did not give a match
  1009       within the sub page ACL (instead, the less restrictive parent page ACL
  1010       was used).
  1011       Non-hierarchical ACL processing (the default) is NOT affected.
  1012     * Creole parser: fix spaces in multiline elements.
  1013     * Use msie.css only for Internet Explorer older than version 8, fixes
  1014       e.g. the double rendering of link icons.
  1015     * http auth: do auth_type comparisons case-insensitively (spec-compliant)
  1016 
  1017   New features:
  1018     * EmbedObject macro: changed default width value for PDF files to 100%
  1019                          (use a recent Adobe Reader to make this work).
  1020     * CopyPage action: added a TextCha for it
  1021 
  1022   Other changes:    
  1023     * Creole parser: Add second license: BSD
  1024 
  1025 
  1026 Version 1.8.3:
  1027   Bug fixes:
  1028     * AttachFile XSS fixes: move escaping to error_msg / upload_form
  1029     * AttachFile move: add more escaping (maybe not XSS exploitable though)
  1030     * email attachments import with xapian indexing enabled: fix AttributeError
  1031     * fix wrong links in attachment notifications
  1032     * AttachFile do=view: quote filename and pagename params for EmbedObject
  1033       macro call
  1034     * AttachFile: fix exception when someone just clicks on upload, without
  1035       giving a file
  1036     * ldap_login: use None as default value for ssl certs/keys (using '' for
  1037       the pathes lets it fail with Connect Error)
  1038     * release edit lock if someone saves an unchanged page
  1039     * fix sendmail.encodeAddress (do not [QP] encode blanks, do not un-
  1040       necessarily use [QP] encoding for pure ascii mail addresses)
  1041     * Fixed docs bug: see HINT about secrets configuration at version 1.8.0
  1042       (1.8.0 Other changes).
  1043     * backup action: add 'self' dummy argument for backup_exclude function
  1044     * login action: fix formatting of error messages
  1045     * unsubscribe action: add msg types so icons get displayed
  1046     * fix quoting for pagehits stats (info action) - was not working for pagenames with blanks
  1047     * macro.TableOfContents: bug fix for MoinMoinBugs/TableOfContentsIgnoresSectionNumbersPragma
  1048 
  1049   New features:
  1050     * added modernized_cms theme
  1051     * use url_prefix_fckeditor if you don't want to use the builtin FCKeditor
  1052       of moin, but a separate one at some specific url
  1053     * action.Load: added textcha feature
  1054     * add mumble protocol (nice and good quality F/OSS VOIP conference chat sw)
  1055     * ldap auth: new name_callback param to create a custom wiki username (not
  1056       the ldap login username).
  1057 
  1058   Other changes:
  1059     * add compatibility code for set to xapwrap.index (fix py 2.6 warnings)
  1060     * wikiutil: MIMETYPES_MORE extended for .md5 as text/plain
  1061 
  1062 
  1063 Version 1.8.2:
  1064   Bug fixes:
  1065     * Fix AttachFile and antispam XSS issues.
  1066     * Modernized, modern and rightsidebar themes: make nonexistent or
  1067       badinterwiki links gray also when they are already visited.
  1068     * Fix anchor parsing for interwiki links and #redirect processing
  1069       instruction.
  1070     * user.apply_recovery_token: key must be of type string (for Python 2.6).
  1071     * Fix MoinMoinBugs/GuiEditorBreaksIndentedTable.
  1072     * Fix autofilter javascript breakage caused by including a databrowser
  1073       widget.
  1074     * Use per-wiki i18n cache (fixes wrong links to other farm wikis).
  1075     * Made cfg.interwikiname and cfg.user_homewiki unicode objects (str only
  1076       worked for ascii names).
  1077     * Xapian search: fixed historysearch.
  1078     * Xapian search indexing:
  1079       * Fix index updating for trivial changes.
  1080       * With history search enabled and in update mode, do not try to re-index
  1081         old page revisions again.
  1082       * With history search enabled, index page attachments only once.
  1083       * Fix last modified time of xapian index (shown on SystemInfo page).
  1084     * Make logging handlers defined in logging.handlers work (e.g.
  1085       class=handlers.RotatingFileHandler)
  1086     * Jabber notifications:
  1087       * Use an RFC compliant message type.
  1088       * Fix user creation notifications.
  1089     * OpenID: Compatibility fix for python-openid 2.x.x (also works with
  1090       1.x.x), fixes crash when trying to associate moin user to OpenID.
  1091     * Have a wikiserverconfig.py in wiki/server/ so setup.py copies it.
  1092     * Fixed inconsistent handling of fragments / anchor IDs:
  1093       * Fixed creole and wiki parser, other parsers might need similar fixes.
  1094       * IDs with blanks, non-ASCII chars etc. are now sanitized in the same way
  1095         for links as well as for link targets, so the user editing a page won't
  1096         have to bother with it.
  1097         E.g. [[#123 foo bar]] will link to:
  1098         * <<Anchor(123 foo bar)>> (moin) or {{#123 foo bar}} (creole)
  1099         * headline = 123 foo bar = (moin / creole)
  1100         Simple rule: if the link and the target are consistent, it should work.
  1101       * The creole wiki parser created non-human-readable sha1 heading IDs
  1102         before 1.8.2, now it creates same (sometimes readable) heading IDs as
  1103         the moin wiki parser.
  1104       * TitleIndex/WordIndex now also use IDs sanitized in that way internally.
  1105       HINT: if you manually worked around the inconsistencies/bugs before, you
  1106             likely have to remove those workarounds now. Same thing if you used
  1107             creole's sha1 heading IDs or IDs on TitleIndex/WordIndex.
  1108 
  1109   Other changes:
  1110     * Updated FCKeditor to 2.6.4 (== many bug fixes in the GUI editor).
  1111     * Enhanced privacy by a new setting: cfg.log_remote_addr (default: True),
  1112       it controls whether moin logs the remote's IP/hostname to edit-log and
  1113       event-log. Use log_remote_addr = False to enhance privacy.
  1114     * Streamline attachment_drawing formatter behaviour.
  1115     * Search results: only redirect to a single search result for titlesearch
  1116       (fuzzy goto functionality), but not for fulltext search results.
  1117 
  1118 
  1119 
  1120 Version 1.8.1:
  1121   Bug fixes:
  1122     * Workaround win32 locking problems (caused by spurious access denied
  1123       exceptions on that platform).
  1124     * Fix unicode errors that happened when password checker failed a password
  1125     * WikiConfig/WikiConfigHelp: fixed wrong language table headings
  1126     * Themes: make the margins around trail line work properly
  1127     * "modernized" theme:
  1128       * make broken links gray
  1129       * add new right/center/left/justify css classes
  1130       * don't force Arial
  1131     * Standalone server: be more specific when catching socket exceptions,
  1132       treat socket errors in http header emission in the same way.
  1133     * GUI editor:
  1134       * Fix heading levels when inserting new headings.
  1135       * Fix headers already sent exception when using e.g. edit LOCKing.
  1136     * Xapian indexing: fixed missing import for execfilter (only happened on
  1137       non-posix platforms like win32)
  1138 
  1139   * New features:
  1140     * Themes:
  1141      * Make the TOC shrinkwrap, add white background to navigation macro.
  1142        The table of contents looked bad spanning the whole width of the page.
  1143        It's made to shrinkwrap now, so it will only get as wide, as the longest
  1144        heading. We use display:inline-table, so this won't work in MS IE6,
  1145        which still displays it the old way.
  1146        Navigation macro now has a white background, to make it more readable
  1147        when it's floating over a pre block or TOC.
  1148      * Make the numbers in lists in table of contents right-aligned.
  1149      * Refactored and extended theme.html_stylesheets() to make alternate
  1150        stylesheets possible. Stylesheet definitions now can either be:
  1151        2-tuples: (media, href)  # backwards compatibility
  1152        or:
  1153        3-tuples: (media, href, title)  # new, for defining alternate stylesheets
  1154        This works within themes as well as in the wiki config.
  1155        See also: http://www.w3.org/Style/Examples/007/alternatives.html
  1156 
  1157 
  1158 Version 1.8.0:
  1159   Note: This is a reduced CHANGES, ommitting details from rc/beta test and
  1160         also less interesting minor changes and fixes. It shows changes
  1161         relative to 1.7.2 release.
  1162         If you want to see full detail, read it there:
  1163         http://hg.moinmo.in/moin/1.8/file/6130eab15936/docs/CHANGES
  1164 
  1165   New Features: ==============================================================
  1166     * HINT: New "modernized" theme - if you use "modern" [default], try:
  1167       theme_default = 'modernized'
  1168       If you find problems with "modernized", please report them because we
  1169       want to use it as default theme in future.
  1170     * GUI Editor:
  1171       * upgraded to use FCKEditor version 2.6.3
  1172       * user can insert and modify various types of MoinMoin links
  1173     * New plugin_dirs setting to allow multiple plugin pathes (additional to
  1174       the automatically configured plugin_dir [default: data_dir/plugin]).
  1175     * @EMAIL@ expands to a MailTo macro call with the obfuscated email address
  1176       of the current user.
  1177     * New macros "WikiConfig" and "WikiConfigHelp".
  1178     * Per-parser quickhelp, 'quickhelp' class variable of parser class.
  1179     * Secure session cookies for https (see cfg.cookie_secure).
  1180     * Added left/center/right/justify css classes to builtin themes.
  1181       Use them like:
  1182       {{{#!wiki justify
  1183       this content is justified....
  1184       }}}
  1185 
  1186   Removed Features: ==========================================================
  1187     * HINT: url_prefix setting (use url_prefix_static or just use the default)
  1188     * traceback_log_dir setting (we just use logging.exception)
  1189     * editor_quickhelp setting (replaced by per-parser quickhelp)
  1190     * Restoring backups with the backup action and related settings (while
  1191       creating backups is no big issue and should work OK, restoring them
  1192       had fundamental issues related to overwriting or not-overwriting of
  1193       existing files - thus we removed the "restore" part of the action and
  1194       recommend that you just contact the wiki server admin in case of trouble,
  1195       give him your wiki backup file and let him carefully restore it.)
  1196     * Removed unmaintained DesktopEdition (moin 1.5.x style) and phpwiki
  1197       migration scripts from contrib/ directory.
  1198 
  1199   Bug Fixes: =================================================================
  1200     * GUI Editor - fixed lots of bugs.
  1201     * Fixing https detection for servers using HTTPS=1 and also for WSGI
  1202       servers not using HTTPS/SSL_ environment, but just wsgi.url_scheme.
  1203     * Search results: link to 'view' rendering of found attachments.
  1204     * Standalone server: fix serverClass and interface argument processing,
  1205       announce used serverClass in log output.
  1206     * mointwisted: fixed Twisted start script.
  1207     * Logging:
  1208       * Use logging framework for messages emitted by warnings module (e.g.
  1209         DeprecationWarning), silence some specific warnings.
  1210       * Removed superfluous linefeeds in timing log output.
  1211     * Bug fix for language not installed (MoinMoinBugs/WikiLanguageNotDefined).
  1212     * Fixed editbar hidden comment link cosmetics for sidebar themes (hide the
  1213       complete list element).
  1214     * MoinMoinBugs/DoubleScriptNameInSitemap (fixing urls given by sitemap
  1215       action, if the wiki does not run in the root url of the site)
  1216     * Fixed backup action configuration (broke on win32).
  1217     * Fixed MoinMoinBugs/PackagesAddRevision.
  1218     * SyncPages: add workaround for callers calling log_status with encoded
  1219       bytestrings.
  1220     * Fixed dbw_hide_buttons javascript.
  1221     * HINT: Jabber bot can now be configured to use an authentication realm
  1222       which is different from the server's hostname; the xmpp_node
  1223       configuration parameter can now contain a full JID and the xmpp_resource
  1224       parameter is no longer supported.
  1225 
  1226   Other Changes: =============================================================
  1227     * HINT: new configuration for misc. secrets, please use either:
  1228           secrets = "MySecretLooongString!" # one secret for everything
  1229       or:
  1230           secrets = {
  1231               'xmlrpc/ProcessMail': 'yourmailsecret', # for mailimport
  1232               'xmlrpc/RemoteScript': 'yourremotescriptsecret',
  1233               'action/cache': 'yourcachesecret', # unguessable cache keys
  1234               'wikiutil/tickets': 'yourticketsecret', # edit tickets
  1235               'jabberbot': 'yourjabberbotsecret', # jabberbot communication
  1236           }
  1237       Secret strings must be at least 10 chars long.
  1238       Note: mail_import_secret setting is gone, use
  1239             secrets["xmlrpc/ProcessMail"] instead of it.
  1240       Note: jabberbot secret setting is gone, use
  1241             secrets["jabberbot"] instead of it.
  1242     * HINT: user_autocreate setting was removed from wiki configuration and
  1243       replaced by a autocreate=<boolean> parameter of the auth objects that
  1244       support user profile auto creation.
  1245     * moin import irclog: use irssi parser to format logs, mapped .irc
  1246       extension to text/plain mimetype.
  1247     * HINT: backup action: backup_exclude (default: "do not exclude anything")
  1248       is now a function f(filename) that tells whether a file should be
  1249       excluded from backup.
  1250       You can get the old regex exclusion functionality by using:
  1251       backup_exclude = re.compile(your_regex).search
  1252       Be careful with your regex, you might need to use re.escape() to escape
  1253       characters that have a special meaning in regexes (e.g.: \.[] etc.).
  1254       If in doubt, maybe just leave backup_exclude at the default and don't
  1255       exclude anything.
  1256     * Speed up javascript comments processing on IE by getElementsByClassName()
  1257     * Added sk (slovak) i18n, updated i18n.
  1258 
  1259 
  1260 1.7.3:
  1261   New features:
  1262     * Secure session cookies for https, see cfg.cookie_secure.
  1263     * Add left/center/right/justify classes to builtin themes.
  1264 
  1265   Fixes:
  1266     * Python 2.3 compatibility fixes.
  1267     * Fixed https detection for servers using HTTPS=1 and also for wsgi servers
  1268       not using HTTPS/SSL_ environment, but just wsgi.url_scheme.
  1269     * GUI editor:
  1270       * Fix crash when editing a page with non-ASCII pagename and inserting a link
  1271       * Fix "headers already sent exception" with edit LOCKs.
  1272     * i18n.__init__: Bug fix for wiki language not installed.
  1273     * Fixed URLs given by sitemap action, if the wiki does not run at / URL.
  1274     * Search results: link to 'view' rendering of found attachments
  1275     * Logging:    
  1276       * Removed superfluous linefeed in timing log output.
  1277       * Use logging framework for messages emitted by warnings module (e.g.
  1278         DeprecationWarning), silence some specific warnings.
  1279     * Fix dbw_hide_buttons javascript.
  1280     * Standalone server:
  1281       * fix serverClass argument processing
  1282       * fix --interface="" argument processing
  1283     * mointwisted:
  1284       * added missing pidFile parameter
  1285       * better use Config.name for pidFile to avoid conflicts and keep same
  1286         behaviour as in the past
  1287     * Jabber bot can now be configured to use an authentication realm which
  1288       is different from the server's hostname
  1289 
  1290 
  1291 Version 1.7.2:
  1292   Fixes:
  1293     * Fix leakage of edit-log file handles (leaked 1 file handle / request!).
  1294     * Fix for MoinMoinBugs/SystemAdminMailAccountData (using POST and forms)
  1295     * Wiki parser: avoid IndexError for empty #! line
  1296     * MonthCalendar macro: fix parameter parsing / url generation
  1297     * Xapian indexing filters (MoinMoin/filter/ or data/plugin/filter/):
  1298       Some indexing filter scripts (e.g. for MS Word documents or PDF files)
  1299       failed on windows because of the single-quote quoting we used (that
  1300       works on Linux and other Posix systems). The fix introduces platform-
  1301       dependant automatic quoting, using double-quotes on win32 and single-
  1302       quotes on posix.
  1303       HINT: if you use own filter plugins based on execfilter, you have to
  1304       update them as the filename quoting (was '%s') is now done automatically
  1305       and must not be part of the command string any more (now just use %s).
  1306       See MoinMoin/filter/ for some up-to-date code (esp. the PDF filter).
  1307     * Prevent CategoryTemplate being listed as a category (it is a Template,
  1308       but matched also the category regex) - added to sample wikiconfig.
  1309     * LDAP auth: fix processing of TLS options
  1310     * UpdateGroup xmlrpc server side: fix wrong arg count error
  1311     * UpdateGroup client: use multicall / auth_token, refactor code so that
  1312       updateGroup function is reusable.
  1313     * Improve Python 2.3 compatibility, add notes where 2.4 is required.
  1314 
  1315 
  1316 Version 1.7.1:
  1317   New features:
  1318     * New 'cache' action (see developer notes).
  1319 
  1320   Fixes:
  1321     * Security fix: XSS fix for advanced search form
  1322     * Avoid creation of new pagedirs with empty edit-log files by just
  1323       accessing a non-existant page. If you used 1.7 before, you likely have
  1324       quite some trash pagedirs now and you can clean them up by using:
  1325       moin --config-dir=... --wiki-url=... maint cleanpage
  1326       This will output some shell script (please review it before running!)
  1327       that can be used to move trash pages into some trash/ directory and also
  1328       moves deleted pages into some deleted/ directory. Maybe keep a copy of
  1329       those directories for a while just for the case.
  1330     * Server specific fixes:
  1331       * standalone (wikiserver.py): fix --pidfile and --group option, fix
  1332         operation without a wikiserverconfig.py (use builtin defaults).
  1333       * mod_python: work around mod_python 3.3.1 problems with file uploads.
  1334         Note: if you are still using mod_python, we strongly recommend you
  1335 	      try out mod_wsgi (in daemon mode) - it has less bugs, better
  1336 	      security, better separation, WSGI is a Python standard, and moin
  1337 	      developers also use WSGI. See HelpOnInstalling/ApacheWithModWSGI.
  1338     * revert action: fixed for deleted pages.
  1339     * Search:
  1340       * Xapian indexing: Removed crappy "hostname" tokenization.
  1341         Fixes MoinMoinBugs/1.7 XapianNotWorkingWithLeadingNumbersInTitle.
  1342         Also tokenize CamelCase parts of non-wikiwords.
  1343       * Make query parser reject more invalid input.
  1344       * If query parsing raises a BracketError, at least tell what the problem
  1345         is (and not just raise empty  ValueError).
  1346       * Category search: ignore traling whitespace after ----
  1347     * Argument parser:
  1348       * Fixed sort() usage in UnitArgument to be Python 2.3 compatible.
  1349       * Fixed MoinMoinBugs/TypeErrorInWikiutils.
  1350     * Macros:
  1351       * TableOfContents: skip outer-most <ol> levels when page isn't using
  1352         the biggest headings
  1353       * MonthCalendar: fix MoinMoinBugs/MonthCalendarBreaksOnApostrophe
  1354     * xslt parser: fix MoinMoinBugs/DoNotConvertUnicodeToUTF8ForXsltParser
  1355     * OpenID RP: make it compatible to python-openid 2.2.x
  1356     * PackagePages.collectpackage: removed encoding from file name of zipfile
  1357     * Surge protection: exclude localnet no matter whether user is known or not.
  1358     * Notifications: fix MoinMoinBugs/DuplicateNewUserNotification
  1359     * Script moin account create/disable/resetpw: checks for already existing
  1360       user now.
  1361 
  1362   Other changes:
  1363     * Prevent CategoryTemplate being listed as a category (it is a Template)
  1364       by changing the default page_category_regex.
  1365 
  1366   Developer notes:
  1367     * New MoinMoin.action.cache - can be used to cache expensively rendered
  1368       output, e.g. generated images). Once put into the cache, moin can emit
  1369       a http response for that content very fast and very efficient (including
  1370       "304 not changed" handling.
  1371     * New file-like API in MoinMoin.caching (good for dealing with medium
  1372       to large files without consuming lots of memory).
  1373     * wikiutil.importPlugin supports getting the whole plugin module object
  1374       by giving function=None.
  1375 
  1376 
  1377 Version 1.7.0:
  1378   Note: This is a reduced CHANGES, ommitting details from rc/beta test and
  1379         also less interesting minor changes and fixes. It shows changes
  1380         relative to 1.6.3 release.

  1383 
  1384   New Features: ==============================================================
  1385     * HINT: we added generic UPDATE instructions as docs/UPDATE.html.
  1386 
  1387     * HINT: Standalone server usage changed:
  1388       * Standalone server can now be started via the "moin" script command,
  1389         optionally backgrounding itself.
  1390         See: moin server standalone --help
  1391       * In the toplevel dir, we have renamed moin.py to wikiserver.py (it was
  1392         often confused with the moin scripting command).
  1393         Now you have:
  1394         * wikiserver.py - to start the standalone server
  1395         * wikiserverconfig.py - to configure the standalone server
  1396         * wikiserverlogging.conf - to configure logging for it (default config
  1397           is ok for all day use, but can easily be modified for debugging)
  1398         * wikiconfig.py - to configure the wiki engine
  1399       * Removed old moin daemonizing script (replaced by moin server standalone
  1400         --start/stop)
  1401       * We now provide the "moin" script command also for people not using
  1402         setup.py, see wiki/server/moin.
  1403 
  1404     * Logging
  1405       * New powerful and flexible logging, please see wiki/config/logging/ -
  1406         HINT: you have to upgrade your server adaptor script (e.g. moin.cgi)
  1407         and load a logging configuration that fits your needs from there, or
  1408         alternatively you can also set MOINLOGGINGCONF environment variable
  1409         to point at your logging config file.
  1410         If you use some of our sample logging configs, make sure you have a
  1411         look INTO them to fix e.g. the path of the logfile it will use.
  1412       * Moin now logs the path from where it loaded its configuration(s).
  1413 
  1414     * Authentication / Sessions:
  1415       * HINT: New authentication plugin system, see HelpOnAuthentication. If
  1416         you do not use the builtin default for 'auth' list, you likely have to
  1417         change your configuration. See wiki/config/snippets/ for some samples.
  1418       * HINT: New session handling system (no moin_session any more, now done
  1419         internally and automatically), see HelpOnSessions for details.
  1420       * Added OpenID client and server support.
  1421         See: HelpOnAuthentication and HelpOnOpenIDProvider.
  1422       * cfg.trusted_auth_methods is a list of auth methods that put an
  1423         authenticated user into the "Trusted" ACL group.
  1424 
  1425     * User profiles / password recovery / notification:
  1426       * New newacount action for creating new user accounts/profiles. If you
  1427         don't want users creating new accounts on their own, you can add this
  1428         action to actions_excluded list.
  1429       * New recoverpass action for password recovery:
  1430         If you forgot your password, recoverpass sends you an email with a
  1431         password recovery token (NOT the encrypted password) that is valid
  1432         for 12 hours.
  1433       * New moin account resetpw script for resetting a user's password by
  1434         the wiki admin.
  1435       * New preferences plugin system, see MoinMoin/userprefs/__init__.py.
  1436       * New notification system with an optional jabber notification bot, see
  1437         HelpOnNotification. HINT: wiki users have to check their notification
  1438         settings, esp. if they want to receive trivial update notifications.
  1439 
  1440     * The diff action now has navigation buttons for prev/next change and also
  1441       a revert button to revert to the revision shown below the diff display.
  1442     * ThemeBase: support Universal Edit Button, see there for details:
  1443       http://universaleditbutton.org/
  1444     * ?action=info&max_count=42 - show the last 42 history entries of the page.
  1445       max_count has a default of default_count and a upper limit of
  1446       limit_max_count - you can configure both in your wiki config:
  1447       cfg.history_count = (100, 200) # (default_count, limit_max_count) default
  1448     * The CSV parser can sniff the delimiter from the first CSV line so other
  1449       delimeters than ";" can be used.
  1450     * Admonition support. Added styling for tip, note, important, warning 
  1451       and caution in the modern theme. For more info see HelpOnAdmonitions.
  1452     * DocBook-formatter:
  1453       * supports HTML entities like &rarr; and &#9731;
  1454       * supports the FootNote macro
  1455       * supports bulletless lists
  1456       * support for admonitions
  1457       * will export the wiki page's edit history as the generated article's
  1458         revision history. Doesn't add history of included pages.
  1459       * supports for the MoinMoin comment element, though only inline comments
  1460         are likely to be valid since the DocBook remark is an inline element.
  1461     * New Hits macro: shows the total hits for the page it is used on.
  1462 
  1463   Removed Features: ==========================================================
  1464     * HINT: Removed attachments direct serving (cfg.attachments - this was
  1465             deprecated since long!). Use AttachFile action to serve attachments.
  1466     * Duplicated file attachment upload code was removed from Load action (just
  1467       use AttachFile action to deal with attachments).
  1468     * Removed 'test' action. If you like to run unit tests, use py.test.
  1469     * Removed Login macro.
  1470 
  1471   Bug Fixes: =================================================================
  1472     * Better handling of ImportErrors (farmconfig, macros, wikiserverconfig).
  1473     * Fix failure of detection of on-disk cache updates.
  1474     * Fix traceback in filesys.py on Mac OS X when "import Carbon" fails.
  1475 
  1476     * AttachFile action / file up- and download / zip support:
  1477       * WSGI: use wsgi.file_wrapper (or a builtin simple wrapper). Fixes memory
  1478         consumption for sending of large file attachments.
  1479       * FastCGI: flush often. Fixes memory consumption for sending of large
  1480         file attachments.
  1481       * Use the open temporary file for receiving file attachment uploads
  1482         (fixes big memory consumption for large file uploads).
  1483       * Catch runtime errors raised by zipfile stdlib modules when trying to
  1484         process a defective zip.
  1485       * When unzipping member files, decode their filenames from utf-8 and
  1486         replace invalid chars.
  1487       * Make error msg less confusing when trying to overwrite a file attachment
  1488         without having 'delete' rights.
  1489 
  1490     * HINT: page_*_regex processing had to be changed to fix category search.
  1491       If you don't use the builtin (english) defaults, you will have to change
  1492       your configuration:
  1493         old (default): page_category_regex = u'^Category[A-Z]'
  1494         new (default): page_category_regex = ur'(?P<all>Category(?P<key>\S+))'
  1495       As you see, the old regex did work for detecting whether a pagename is
  1496       a category, but it could not be used to search for a category tag in the
  1497       page text. The new regex can be used for both and identifies the complete
  1498       category tag (match in group 'all', e.g. "CategoryFoo") as well as the
  1499       category key (match in group 'key', e.g. "Foo") by using named regex
  1500       groups. \S+ means the category key can be anything non-blank.
  1501       If you like to simultaneously support multiple languages, use something
  1502       like this: ur'(?P<all>(Kategorie|Category)(?P<key>\S+))'
  1503       HINT: after changing your configuration, please rebuild the cache:
  1504         * stop moin
  1505         * moin ... maint cleancache
  1506         * start moin
  1507       If you don't do this, your groups / dicts will stop working (and also
  1508       your ACLs that use those groups). You better do a test whether it works.
  1509 
  1510     * Xapian search / indexing / stemming:
  1511       * Use text/<format> as mimetype for pages.
  1512       * Index also major and minor for mimetypes, so it will find 'text' or
  1513         'plain' as well as 'text/plain'
  1514       * Fix searching for negative terms.
  1515       * Improve result list ordering.
  1516       * Index filters: redirect stderr to logging system.
  1517       * Remove crappy num regex from WikiAnalyzer, improve tokenization.
  1518       * Fix AttributeError that happened when trying to access an attribute only
  1519         used with xapian search (but regex search is not done by xapian)
  1520       * Fix IndexErrors happening when pages are renamed/nuked after the index
  1521         was built.
  1522       * Fixed indexing of WikiWords (index "WikiWords", "Wiki" and "Words").
  1523       * Fix crash if default language is un-stemmable.
  1524       * xapian_stemming: removed some strange code (fixes search
  1525         title:lowercaseword with xapian_stemming enabled)
  1526       * Fixed category indexing (index CategoryFoo correctly as CategoryFoo, not
  1527         Foo - for all languages, see page_*_regex change above).
  1528     * Builtin search: support mimetype: search for pages for the builtin search
  1529       engine (using text/<format>).
  1530 
  1531     * Parser fixes:
  1532       * Wiki: fix subscript parsing (was broken for cases like 'a,,1,2,,').
  1533       * Docbook: fixed detection of WikiWords.
  1534       * All: Add ssh protocol to url_schemas for ssh:... URLs.
  1535 
  1536     * XMLRPC:
  1537       * Fix xmlrpc request.read() call to use content-length, if available,
  1538         fixes hangs with wsgiref server.
  1539       * Wiki xmlrpc getPageInfoVersion() fixed:
  1540         * works correctly now for old page versions (was unsupported)
  1541         * works correctly now for current page version (reported wrong
  1542           data when a page had attachment uploads after the last page
  1543           edit)
  1544         * returns a Fault if it did not find a edit-log entry
  1545 
  1546   Other Changes: =============================================================
  1547     * Using better ACLs and comments on system/help pages now, just taking
  1548       away 'write' permission, but using default ACLs for everything else.
  1549     * HINT: If you want to use xapian based indexed search, you need to have
  1550       Xapian >= 1.0.0 (and you can remove PyStemmer in case you have installed
  1551       it just for moin - we now use the stemmer built into Xapian as it
  1552       supports utf-8 since 1.0.0).
  1553     * Changed default value of cfg.search_results_per_page to 25.
  1554     * Surge Protection: If a user is authenticated by a trusted authentication
  1555       (see also cfg.auth_methods_trusted) then he/she won't trigger surge
  1556       protection, but moin will just log a INFO level log msg with the user's
  1557       name so you can find the culprit in case he/she is overusing ressources.
  1558     * HINT: Added MyPages and CopyPage to actions_excluded because MyPages
  1559       doesn't work without special SecurityPolicy anyway and CopyPage has
  1560       questionable behaviour.
  1561     * Load action now just creates a new revision of the target page, the
  1562       target pagename defaults to the current page name and can be edited.
  1563       If the target pagename is empty, moin tries to derive the target pagename
  1564       from the uploaded file's name.
  1565       Load tries to decode the file contents first using utf-8 coding and, if
  1566       that fails, it forces decoding using iso-8859-1 coding (and replacing
  1567       invalid characters).
  1568     * HINT: cfg.show_login is gone, see code in theme/__init__.py, this may
  1569       affect many themes!
  1570     * HINT: a new userprefs/ plugin directory will be created by the usual
  1571       "moin migration data" command.
  1572     * DocBook-formatter:
  1573       * generates a valid DOCTYPE
  1574       * table support has been improved
  1575       * handling of definitions and glossaries is more robust
  1576       * supports program language and line numbering in code areas
  1577     * HINT: ldap_login behaves a bit different now:
  1578       In previous moin versions, ldap_login tended to either successfully
  1579       authenticate a user or to completely cancel the whole login process in
  1580       any other case (including ldap server down or exceptions happening).
  1581       This made subsequent auth list entries rather pointless.
  1582       Now it behaves like this:
  1583         * user not found in LDAP -> give subsequent auth list entries a
  1584           chance to authenticate the user (same happens if it finds multiple
  1585           LDAP entries when searching - it logs an additional warning then).
  1586         * user found, but wrong password -> cancel login
  1587         * ldap server not reachable or other exceptions -> give subsequent
  1588           auth list entries a chance
  1589       So please make sure that you really trust every auth list entry you have
  1590       configured when upgrading or it might maybe change behaviour in a
  1591       unexpected or unwanted way.
  1592     * ldap_login now supports failover: if it can't contact your LDAP server
  1593       (e.g. because it is down or unreachable), it will just continue and
  1594       try to authenticate with other authenticators (if there are any in
  1595       cfg.auth list). So if you have some mirroring LDAP backup server, just
  1596       put another authenticator querying it there:
  1597           ldap_auth1 = LDAPAuth(server_uri='ldap://mainserver', ...)
  1598           ldap_auth2 = LDAPAuth(server_uri='ldap://backupserver', ...)
  1599           auth = [ldap_auth1, ldap_auth2, ]
  1600 
  1601   Developer notes: ===========================================================
  1602     * Page.last_edit() is DEPRECATED, please use Page.edit_info().
  1603     * Page._last_edited() is GONE (was broken anyway), please use
  1604       Page.editlog_entry().
  1605     * New request.send_file() call, making it possible to use server-specific
  1606       optimizations.
  1607     * getText's (aka _()) 'formatted' keyword param (default: True in 1.6 and
  1608       early 1.7) was renamed/changed: it is now called 'wiki' and defaults to
  1609       False. Example calls:
  1610       _('This will NOT get parsed/formatted by MoinMoin!')
  1611       _('This will be parsed/formatted by MoinMoin!', wiki=True)
  1612       _('This will be used as a left side of percent operator. %s',
  1613         wiki=True, percent=True)
  1614     * Page.url 'relative' keyword param (default: True in 1.6 and early 1.7)
  1615       was changed to default False).
  1616     * The themedict no longer contains 'page_user_prefs' and 'user_prefs',
  1617       this may affect custom themes.
  1618     * The rst-parser's admonition class names are no longer prepended with
  1619       "admonition_". Instead the class names are now for example "note"
  1620       and not "admonition_note".
  1621 
  1622 
  1623 Version 1.6.3:
  1624   Fixes:
  1625     * Security fix: a check in the user form processing was not working as
  1626       expected, leading to a major ACL and superuser priviledge escalation
  1627       problem. If you use ACL entries other than "Known:" or "All:" and/or
  1628       a non-empty superuser list, you need to urgently install this upgrade.
  1629     * Security fix: if acl_hierarchic=True was used (False is the default),
  1630       ACL processing was wrong for some cases, see
  1631       MoinMoinBugs/AclHierarchicPageAclSupercededByAclRightsAfter
  1632     * For {{transclusion_targets}} we checked the protocol to be http(s),
  1633       this check was removed (because file: and ftp: should work also) and
  1634       it's not moin's problem if the user uses silly protocols that can't
  1635       work for that purpose.
  1636     * Fixed TableOfContents macro for included pages.
  1637     * server_fastcgi: added Config.port = None. If you want to use some port
  1638       (not a fd), you can set it now in your Config, e.g. port = 8888.
  1639     * category: search matches categories even if there are comment lines
  1640       between the horizontal rule and the real categories, e.g.:
  1641       ... some page text ...
  1642       ----
  1643       ## optionally some comments, e.g. about possible categories:
  1644       ## CategoryJustACommentNotFound
  1645       CategoryTheRealAndOnly
  1646 
  1647       Note: there might be multiple comment lines, but all real categories
  1648             must be on a single line either directly below the ---- or
  1649             directly below some comment lines.
  1650   
  1651   Other changes:
  1652     * Added 'notes' to config.url_schemas, so you can use notes://notessrv/...
  1653       to invoke your Lotus Notes client.
  1654     * After creating a new user profile via UserPreferences, you are logged
  1655       in with that user (no need to immediately enter the same name/password
  1656       again for logging in).
  1657 
  1658 
  1659 Version 1.6.2:
  1660   Fixes:
  1661     * Security fix: check the ACL of the included page for the rst parser's
  1662       include directive.
  1663     * Potential security/DOS fix: we removed cracklib / python-crack support
  1664       in password_checker as it is not thread-safe and caused segmentation
  1665       faults (leading to server error 500 because the moin process died).
  1666     * Fix moin_session code for auth methods other than moin_login (e.g. http).
  1667       If you have worked around this using moin_anon_session, you can remove
  1668       this workaround now (except if you want anon sessions for other reasons).
  1669     * Fix moin_session code to delete invalid session cookies and also create
  1670       a new session cookie if it got a valid user_obj at the same time.
  1671     * Fix xmlrpc applyAuthToken: give good error msg for empty token.
  1672     * Fixed category search, use category:CategoryFoo as search term.
  1673     * xapian_stemming = False (changed default) to workaround some problems
  1674       in the code enabled by it. Fixes the problems when searching for
  1675       lowercase or numeric titles or word fragments with the builtin search.
  1676     * Fix trail for anon users without a session, do not show a single page.
  1677     * Fix MoinMoinBugs/WikiSyncComplainsAboutTooOldMoin.
  1678     * Wiki parser: fixed strange insertion of unwanted paragraphs.
  1679     * Wiki parser: fix interwiki linking:
  1680       Free interwiki links did not change since 1.5 (they still require to match
  1681       [A-Z][A-Za-z]+ for the wikiname part, i.e. a ASCII word beginning with an
  1682       uppercase letter).
  1683       Bracketed interwiki links now behave similar to how they worked in 1.5:
  1684       Moin just splits off the part left of the colon - no matter how it looks
  1685       like. It then tries to find that in the interwiki map. If it is found,
  1686       a interwiki link gets rendered. If it is not found, moin will render a
  1687       link to a local wiki page (that has a colon in the pagename). It will
  1688       also render a local wiki page link if there is no colon at all, of course.
  1689       Examples:
  1690       [[lowercasewikiname:somepage]] does an interwiki link (if in the map).
  1691       [[ABC:n]] does a local link to page ABC:n (if ABC is NOT in the map).
  1692     * Wiki parser: fix interwiki linking for the case that there are query args
  1693       in the interwiki map entry and you give additional query args via link
  1694       markup (uses correct query arg separator now), e.g.:
  1695       [[Google:searchterm|search this|&foo=bar]]
  1696     * Creole parser: fixed bug that prevents images inside links.
  1697     * Python parser: catch indentation error.
  1698     * PageEditor: fixed copyPage for write restricted pages.
  1699     * GUI editor: fixed javascript error with too complex word_rule regex,
  1700       see MoinMoinBugs/GuiEditorSyntaxError.
  1701     * Fixed FCKeditor dialog boxes for FireFox3.
  1702     * NewPage macro/newpage action: fixed for non-ascii template pagenames.
  1703     * FootNote macro: Fix MoinMoinBugs/FootNoteNumbering.
  1704     * EmbedObject macro: bug fix for image mimetype
  1705     * WSGI:
  1706       * fix TWikiDraw saving a drawing by also evaluating the query args.
  1707       * work around unpythonic WSGI 1.0 read() API, fixing broken xmlrpc
  1708         putPage with mod_wsgi
  1709     * Fix highlighting (see MoinMoinBugs/SearchForPagesWithComments).
  1710     * Fix logfile code for EACCESS errors.
  1711     * Removed the "logging initialized" log messages because it was issued once
  1712       per request for CGI.
  1713 
  1714   Other changes:
  1715     * Show "Comments" toggling link in edit bar only if the page really
  1716       contains comments.
  1717     * Made default configuration of surge protection a bit more forgiving,
  1718       especially for edit action which is currently also used for previews.
  1719     * Updated i18n, system/help pages, added Macedonian system text translation.
  1720     * Improved moin xmlrpc write command's builtin docs and auto-append
  1721       ?action=xmlrpc2 to the target wiki url given.
  1722 
  1723 
  1724 Version 1.6.1:
  1725   New features:
  1726     * Improved params for [[target|label|params]]:
  1727       Added accesskey link tag attribute, e.g.: [[target|label|accesskey=1]].
  1728       Additionally to specifying link tag attributes (like class=foo), you can
  1729       now also specify &key=value for getting that into the query string of
  1730       the link URL.
  1731       The "&" character is important, don't forget it or it won't get into the
  1732       query string!
  1733       E.g. for an attachment, you can use:
  1734       [[attachment:foo.pdf|Direct download of foo.pdf|&do=get]]
  1735       E.g. for linking to some specific diff, you can use:
  1736       [[SomePage|see that diff|&action=diff,&rev1=23,&rev2=42]]
  1737       See also the updated HelpOnLinking page!
  1738     * AdvancedSearch: make multipe categories/languages/mimetype selections possible
  1739     * Added a configuration directive to only do one bind to the LDAP server.
  1740       This is useful if you bind as the user the first time.
  1741       ldap_bindonce = False # default
  1742 
  1743   Fixes:
  1744     * Fix XSS issue in login action.
  1745     * Fix wrong pagename when creating new pages on Mac OS X - that was a big
  1746       showstopper for moin 1.6.0 on Mac OS X.
  1747     * Fixed 1.6 migration script:
  1748       Make sorting python 2.3 compatible.
  1749       Just skip corrupted event log lines.
  1750       Fix link conversion by using data.pre160 as data_dir.
  1751       Fix bad /InterWiki pagenames when encountering interwiki links with bad
  1752       wiki names.
  1753       Improve ImageLink conversion by using its argument parser code.
  1754       Added STONEAGE_IMAGELINK (default: False) switch to wiki markup converter,
  1755       toggle it if you had a very old ImageLink macro in production and the
  1756       converter output has target and image interchanged.
  1757       Fixed UnicodeDecodeError for wrongly encoded attachment filenames.
  1758     * Wiki parser:
  1759       Fix parsing of link/transclusion description and params.
  1760       Fix relative attachment targets.
  1761       Fix supported URL schemes (some got lost since 1.5.8).
  1762       Showing an upload link for non-existing non-text/non-image transclusions
  1763       now (like e.g. *.pdf).
  1764     * RST parser: fix attachment: and drawing: processing
  1765     * Fix quickhelp when editing RST markup pages.
  1766     * Fix Despam action: editor grouping was broken, increase time interval
  1767       to 30 days.
  1768     * Fix AdvancedSearch domain:system search crashing.
  1769     * Only switch off xapian search if we didn't use it because of missing index.
  1770     * Fix saving twikidraw drawings by removing 'java' from spider regex.
  1771     * Fix classic theme's unsubscribe icon's action link.
  1772     * Fix AttachFile action: don't show unzip for packages, only show install
  1773       for superuser.
  1774     * Fix "su user" troubles on UserPreferences.
  1775     * Removed unit tests from ?action=test (due to changes in our test
  1776       environment, using py.test now, this was broken).
  1777     * Duplicated the top directories' moin.py to wiki/server/moin.py so it gets
  1778       installed by setup.py.
  1779     * Fix MoinMoinBugs/1.6.0LanguageIgnoreBrowserConfigurationError
  1780     * Fix MoinMoinBugs/MoveAttachmentNotWorkingWithModPython
  1781     * Fix MoinMoinBugs/1.6.0SupplementationAndAccessRights
  1782     * Fix MoinMoinBugs/RenamingUserAllowsOldUsernameToLogin
  1783     * Fix MoinMoinBugs/GuiEditorExcelPasteExpatErrorUnboundPrefix
  1784 
  1785   Other changes:
  1786     * I18n texts, system and help pages updated, please update your underlay
  1787       directory (see wiki/underlay/...).
  1788     * Improved "moin" script help, invoke it with "moin ... package command --help".
  1789     * Added some .ext -> mimetype mappings missing on some systems (like Mac OS X).
  1790     * Removed ImageLink macro, as this can be easily done with moin wiki link
  1791       syntax now - see HelpOnMacros/ImageLink (the 1.6 migration scripts convert
  1792       all ImageLink calls to moin wiki link syntax).
  1793     * Updated EmbedObject macro.
  1794 
  1795 
  1796 Version 1.6.0:
  1797  * This is a reduced CHANGES, ommitting details from rc/beta test and also
  1798    less interesting minor changes and fixes. If you want to see full detail,
  1799    read it there: http://hg.moinmo.in/moin/1.6/file/640f21787334/docs/CHANGES
  1800 
  1801    It took MoinMoin development a lot of work and time to implement all the new
  1802    and fixed stuff, so please, before asking for support:
  1803    * take the time to read all the stuff below
  1804    * read the new help pages (copy them from wiki/underlay/ directory)
  1805 
  1806  * HINT: If you are upgrading from a older moin version and want to keep your
  1807    existing data directory, it is essential that you read and follow
  1808    README.migration because the wiki markup and user profiles changed significantly.
  1809    See also more HINTs below...
  1810 
  1811   New features: ==============================================================
  1812 
  1813   User interface: ------------------------------------------------------------
  1814     * Removed "underscore in URL" == "blank in pagename magic" - it made more
  1815       trouble than it was worth. If you still want to have a _ in URL, just
  1816       put a _ into pagename.
  1817     * Discussion pages, see FeatureRequests/DiscussionAndOrCommentPages.
  1818     * cfg.password_checker (default: use some simple builtin checks for too
  1819       easy passwords and, if available, python-crack).
  1820       Use password_checker = None to disable password checking.
  1821     * We now have a drafts functionality (no */MoinEditorBackup pages any
  1822       more):
  1823       * If you edit a page and cancel the edit, use preview or save, a draft
  1824         copy gets saved for you to a internal cache area (data/cache/drafts/).
  1825       * If it is a save what you did and it succeeds, the draft copy gets
  1826         killed right afterwards.
  1827       * If you accidentally used cancel or your browser or machine crashes
  1828         after you used preview, then just visit that page again and edit it.
  1829         the editor will notify you that there is a draft of this page and you
  1830         will see a "Load draft" button. Click on it to load the draft into the
  1831         editor and save the page.
  1832       * The draft storage is per user and per page, but only one draft per page.
  1833     * cfg.quicklinks_default and cfg.subscribed_pages_default can be used to
  1834       preload new user profiles with configurable values.
  1835     * attachment links for non-existing attachments look different now:
  1836       the note about the non-existing attachment moved to the link title,
  1837       the link is shown with nonexistent class (grey).
  1838     * attachment embeddings for non-existing attachments show a grey clip
  1839     * The list of InterWiki sites is editable in the wiki (page InterWikiMap),
  1840       it is getting reloaded every minute.
  1841     * We support some new languages and also have new underlay pages, thanks
  1842       to all translators and people helping with the docs!
  1843 
  1844   Actions: -------------------------------------------------------------------
  1845     * Synchronisation of wikis using the SyncPages action.
  1846     * Xapian (see http://xapian.org/) based indexed search code.
  1847       To use this:
  1848       * Install xapian-core and xapian-bindings on your machine.
  1849         We used 0.9.4, but newer code should hopefully work, too.
  1850       * cfg.xapian_search = True
  1851       * Execute this to build the index:
  1852         $ moin ... index build   # indexes pages and attachments
  1853         $ moin ... index build --files=files.lst  # same plus a list of files
  1854         You should run those commands as the same user you use for your wiki,
  1855         usually this is the webserver userid, e.g.:
  1856         $ sudo -u www-data moin --config=... --wiki-url=wiki.example.org/ \
  1857                index build --files=files.lst
  1858     * New searches:
  1859         - LanguageSearch: language:de
  1860         - CategorySearch: category:Homepage
  1861         - MimetypeSearch: mimetype:image/png (for attachments/files)
  1862         - DomainSearch: domain:underlay or domain:standard
  1863         - History Search: available in advanced ui
  1864       Note: Some currently only available when Xapian is used.
  1865     * New config options and their defaults:
  1866         xapian_search        False  enables xapian-powered search
  1867         xapian_index_dir     None   directory for xapian indices
  1868                                     (can be shared for wiki farms)
  1869         xapian_stemming      True   toggles usage of stemmer, fallback
  1870                                     to False if no stemmer installed
  1871         search_results_per_page 10  determines how many hits should be
  1872                                     shown on a fullsearch action
  1873         xapian_index_history False  indexes all revisions of pages to
  1874                                     allow searching in their history
  1875     * Speeded up linkto search by avoiding read locks on the pagelinks file.
  1876 
  1877     * The action menu now calls the actions for the revision of the page you
  1878       are currently viewing. If you are viewing the current page revision, you
  1879       get the same behaviour as in moin 1.5, but if you are viewing an old
  1880       page revision, action "raw" will now show you the raw text of this OLD
  1881       revision (not of the current revision as moin 1.5 did it).
  1882       Note that not every action does evaluate the rev=XX parameter it gets.
  1883       Also please note that the edit, info, ... links in the editbar do NOT
  1884       use the rev parameter, but operate on the latest page revision (as
  1885       they did in moin 1.5).
  1886     * Info action lost the links for "raw", "print" and "revert" actions,
  1887       because you can now just view an old revision and select those actions
  1888       from the menu there.
  1889     
  1890     * ?action=sitemap emits a google sitemap (XML), listing all your wiki pages
  1891       and the wiki root URL.
  1892       Page                      Priority / Frequency / Last modification
  1893       --------------------------------------------------------------------
  1894       /                         1.0 / hourly / <now>
  1895       cfg.page_front_page       1.0 / hourly / page last edit
  1896       TitleIndex,RecentChanges  0.9 / hourly / <now>
  1897       content pages             0.5 / daily / page last edit
  1898       system/help pages         0.1 / yearly / page last edit
  1899 
  1900     * Action DeletePage and RenamePage can now be used for subpages of a page, too.
  1901     * Added Action CopyPage so you can use now an existing page or page hierarchy
  1902       as template for a new page, see FeatureRequests/CloneOrCopyPages.
  1903     * "Package Pages" action supports attachments now.
  1904     * Added SisterPages support:
  1905       * action=sisterpages will generate a list of url pagename lines for all
  1906         pages in your moin wiki.
  1907       * action=pollsistersites will poll all sister sites listed in
  1908         cfg.sistersites = [(wikiname, fetchURL), ...]
  1909         The fetch URL for the sistersites depends on the wiki engine, e.g.:
  1910         # moin based wiki:
  1911         ('MoinExample', 'http://moin.example.org/?action=sisterpages')
  1912         # oddmuse based wiki:
  1913         ('EmacsWiki', 'http://www.emacswiki.org/cgi-bin/test?action=sisterpages')
  1914         # JspWiki based wiki:
  1915         ('JspWiki', 'http://www.jspwiki.org/SisterSites.jsp')
  1916       * If the current page exists on some sister wiki, a link to it will be
  1917         added to the navibar.
  1918       You can use sister wikis for adding another dimension to your wiki UI: use
  1919       it for simple multi language support, or for comments, or anything else
  1920       "related" you need.
  1921       TODO: add sistersites_force with sister sites we link to even if they do not
  1922             have the page yet (will work only for moin as we don't know
  1923             pagename>url transformation of other wikis)
  1924     * showtags action that lists all tags related to a page.
  1925     * action=view does use mimetypes of EmbedObject too and text files will be shown
  1926       by using their colorized parsers
  1927 
  1928   Macros: --------------------------------------------------------------------
  1929     * RecentChanges:
  1930       * If a change has happened after your bookmark, the updated/new/renamed
  1931         icon links to the bookmark diff.
  1932       * If a page does not exist any more (because it was deleted or renamed),
  1933         we link the deleted icon to the diff showing what was deleted (for the
  1934         delete action). For the rename action, we just show the deleted icon.
  1935     * Conflict icon in RecentChanges is shown if a edit conflict is detected.
  1936     * Enhanced SystemAdmin's user browser, so a SuperUser can enable/disable
  1937       users from there.
  1938     * Included EmbedObject macro for embedding different major mimetypes:
  1939       application, audio, image, video, chemical, x-world. 
  1940       You are able to change the defaults of allowed mimetypes in the config
  1941       var mimetypes_embed. The config var mimetypes_xss_protect is used to deny
  1942       mimetypes. The order of both variables is Allow, Deny (mimetypes_embed,
  1943       mimetypes_xss_protect).
  1944     * Added support for @SELF to the NewPage macro.
  1945     * GetText2 macro that allows to translate messages that contain data.
  1946     * Make the FootNote macro filter duplicates and display a list of numbers
  1947       instead of a list of identical footnotes. Thanks to Johannes Berg for the
  1948       patch.
  1949 
  1950   Parsers: -------------------------------------------------------------------
  1951     * Moin Wiki parser: Changed markup for links, images and macros, see these
  1952       wiki pages: HelpOnLinking, HelpOnMacros
  1953     * New wiki markup for /* inline comments */ - they get rendered as a span
  1954       with class="comment", see next item:
  1955     * There is a new item in the edit bar: "Comments". If you click it, the
  1956       visibility of all class "comment" tags will be toggled. There is a user
  1957       preferences item "show_comments" to set if the default view shows them or not.
  1958     * The wiki parser can be used with css classes now:
  1959       {{{#!wiki comment
  1960       This will render output within a div with class "comment".
  1961       You can use any wiki markup as usual.
  1962       }}}
  1963       You can also combine multiple css classes like this:
  1964       {{{#!wiki red/dotted/comment
  1965       This will render a red background, dotted border comment section.
  1966       }}}
  1967       The same thing will work for any other css classes you have.
  1968       If the css classes contain the word "comment", they will trigger some
  1969       special feature, see next item:
  1970     * Wiki nested parser/pre sections work now, using this syntax:
  1971       a) just use more curly braces if you have 3 closing in your content:
  1972          {{{{
  1973          }}} <- does not terminate the section!
  1974          }}}}
  1975       b) use {{{ + some magic string:
  1976          {{{somemagicstring
  1977          }}} <- does not terminate the section!
  1978          somemagicstring}}}
  1979       c) {{{whatever#!python
  1980          # py code
  1981          whatever}}}
  1982       Pitfall: stuff like below does not work as it did in 1.5:
  1983          {{{aaa
  1984          bbb}}}
  1985       Solution:
  1986          {{{
  1987          aaa
  1988          bbb
  1989          }}}
  1990     * Added support for ircs: URLs (secure IRC).
  1991     * New text/creole parser that allows you to use WikiCreole 1.0 markup,
  1992       use #format creole.
  1993     * HTML parser (called "html") that allows you to use HTML on the page.
  1994       Thanks to the trac team for the nice code.
  1995     * Added the diff parser from ParserMarket, thanks to Emilio Lopes, Fabien
  1996       Ninoles and Juergen Hermann.
  1997 
  1998   XMLRPC: --------------------------------------------------------------------
  1999     * actions_excluded now defaults to ['xmlrpc'] - this kind of disables the
  2000       built-in wiki xmlrpc server code (not completely: it will just answer
  2001       with a Fault instance for any request). If you want to use xmlrpc v1 or
  2002       v2, you have to remove 'xmlrpc' from the actions_excluded list (for
  2003       example if you want to use wikisync, mailimport or any other feature
  2004       using xmlrpc). If you enable xmlrpc, it will be possible that someone
  2005       changes your wiki content by using xmlrpc (it will of course honour ACLs).
  2006     * New XMLRPC methods (see doc strings for details):
  2007       * getMoinVersion
  2008       * system.multicall -- multicall support
  2009       * Authentication System: getAuthToken/appyAuthToken
  2010       * getDiff -- method to get binary diffs
  2011       * mergeDiff -- method to local changes remotely
  2012       * interwikiName -- method to get the IWID and the interwiki moniker
  2013       * getAllPagesEx -- method to get the pagelist in a special way (revnos,
  2014         no system pages etc.)
  2015       * getAuthToken -- make and authentication token by supplying username/password
  2016       * applyAuthToken -- set request.user for following xmlrpc calls (within the
  2017                           same multicall)
  2018       * getUserProfile -- method to get user profile data for request.user
  2019     * Added XMLRPC methods for attachment handling. Thanks to Matthew Gilbert.
  2020     * XMLRPC putPage method adjusted to new AuthToken, config vars 
  2021       xmlrpc_putpage_enabled and xmlrpc_putpage_trusted_only removed.
  2022 
  2023   Scripts / Commandline interface: -------------------------------------------
  2024     * moin export dump now better conforms to the theme guidelines.
  2025     * Added a --dump-user option to the moin export dump command.
  2026       Thanks to Oliver O'Halloran.
  2027 
  2028   Security / Auth / AntiSpam / etc.: -----------------------------------------
  2029     * Hierarchical ACLs are now supported, i.e. pages inheriting permissions
  2030       from higher-level pages. See HelpOnAccessControlLists.
  2031     * If you have "#acl" (without the quotes) on a page, this means now:
  2032       "this page has own (empty) ACLs, so do not use acl_rights_default here"
  2033       Please note that this is COMPLETELY DIFFERENT from having no ACL line at
  2034       all on the page (acl_rights_default is used in that case).
  2035     * Antispam master url is now configurable via cfg.antispam_master_url.
  2036       The default is to fetch the antispam patterns from MoinMaster wiki.
  2037     * Antispam now checks the edit comments against BadContent also.
  2038     * TextCHAs (text-form CAPTCHAs).
  2039       Due to increasingly annoying wiki spammers, we added the option to use
  2040       TextCHAs (for page save (not for preview!), for attachment upload, for
  2041       user creation (not for profile save)).
  2042       This function is disabled by default. If you run a wiki that is editable
  2043       by anonymous or non-approved users from the internet (i.e. All: or Known:
  2044       in ACL terms), you should enable it in your wiki config by:
  2045       textchas = { # DO NOT USE EXACTLY THESE QUESTIONS!!!
  2046           'en': {
  2047               u'H2O is ...': u'water', # bad: too common
  2048               u'2 apples and three bananas makes how many fruits?': ur'(five|5)', # good
  2049               u'2 apples and three pigs makes how many fruits?': ur'(two|2)', # good
  2050               u'2+3': ur'5', # bad: computable
  2051               u'
  2052           },
  2053           'de': { # for german users
  2054               u'H2O ist ...': u'wasser',
  2055           },
  2056       }
  2057       This means that english users will get some random question from the 'en'
  2058       set, german users will get some from the 'de' set. If there is no 'de'
  2059       set configured, moin will fallback to language_default and then to 'en',
  2060       so make sure that you at least have a 'en' set configured (or whatever
  2061       you have set as language_default).
  2062       You need to use unicode for the questions and answers (see that u"...").
  2063       For the answer, you need to give a regular expression:
  2064       * In the easiest case, this is just some word or sentence (first en
  2065         example). It will be matched in a case-insensitive way.
  2066       * For more complex stuff, you can use the power of regular expressions,
  2067         e.g. if multiple answers are correct (second en example). Any answer
  2068         matching the regular expression will be considered as correct, any
  2069         non-matching answer will be considered as incorrect.
  2070 
  2071       Tipps for making it hard to break for the spammers and easy for the users:
  2072       * Use site-specific (not too common) questions.
  2073       * Don't use too hard questions (annoys legitimate users).
  2074       * Don't use computable questions.
  2075       * Don't reuse textchas from other sites.
  2076 
  2077       textchas_disabled_group = None # (default)
  2078       Set this to some group name and noone in this group will get textchas.
  2079       E.g.: textchas_disabled_group = u'NoTextChasGroup'
  2080 
  2081     * The login page gives now the possibility to recover a lost password, thanks to 
  2082       Oliver Siemoneit. This is especially useful for wikis where access to user 
  2083       preferences is restricted by acl.
  2084     * Session handling for logged-in users and (not by default due to expiry
  2085       problems) anonymous users.
  2086     * Updated the ldap_login code from 1.5 branch, supports TLS now.
  2087       See MoinMoin/config/multiconfig.py for supported configuration options
  2088       and their defaults (and please just change what you need to change,
  2089       in your wikiconfig).
  2090     * Interwiki auth: You need to define cfg.trusted_wikis and
  2091        cfg.user_autocreate to use it. Logging in works by entering:
  2092       Name: RemoteWikiName RemoteUserName
  2093       Password: remotepass
  2094       Then moin contacts RemoteWikiName after looking it up in the interwiki
  2095       map and tries to authenticate there using RemoteUserName and remotepass.
  2096       If it succeeds, the remote wiki will return the remote user profile items
  2097       and your local moin will autocreate an account with these values.
  2098 
  2099   Server / Network / Logging: ------------------------------------------------
  2100     * The standalone server script moved to the toplevel directory. This makes
  2101       it possible to directly start moin.py without additional configuration
  2102       to run a MoinMoin DesktopEdition like wiki setup.
  2103       Be careful: DesktopEdition uses relaxed security settings only suitable
  2104       for personal and local use.
  2105     * Added TLS/SSL support to the standalone server. Thanks to Matthew Gilbert.
  2106       To use TLS/SSL support you must also install the TLSLite library
  2107       (http://trevp.net/tlslite/). Version 0.3.8 was used for development and
  2108       testing.
  2109 
  2110     * cfg.log_reverse_dns_lookups [default: True] - you can set this to False
  2111       if rev. dns lookups are broken in your network (leading to long delays
  2112       on page saves). With False, edit-log will only contain IP, not hostname.
  2113     * Added support for "304 not modified" response header for AttachFile get
  2114       and rss_rc actions - faster, less traffic, less load.
  2115 
  2116     * Added logging framework, using stdlib's "logging" module. Just do
  2117       import logging ; logging.debug("your text"). Depending on configuration
  2118       in the server Config class, your stuff will be written to screen (stderr),
  2119       to a moin logfile, to apache's error.log, etc.:
  2120       logPath = None # 'moin.log'
  2121       loglevel_file = None # logging.DEBUG/INFO/WARNING/ERROR/CRITICAL
  2122       loglevel_stderr = None # logging.DEBUG/INFO/WARNING/ERROR/CRITICAL
  2123       NOTE: this is NOT in wikiconfig, but e.g. in moin.cgi or moin.py or ...
  2124 
  2125     * Added some experimental and disabled code, that uses x-forwarded-for
  2126       header (if present) to get the right "outside" IP before a request
  2127       enters our chain of trusted (reverse) proxies.
  2128       This code has the problem that we can't configure it in wikiconfig, so
  2129       if you want to use it / test it, you have to edit the moin code:
  2130       MoinMoin/request/__init__.py - edit proxies_trusted (near the top).
  2131       We will try to make this easier to configure, but there was no time left
  2132       before 1.6.0 release for doing bigger code refactorings needed for that.
  2133 
  2134   Mail: ----------------------------------------------------------------------
  2135     * You can send email to the wiki now (requires xmlrpc), see:
  2136       FeatureRequests/WikiEmailIntegration, HelpOnConfiguration/EmailSupport
  2137 
  2138     * Mail notifications contain a link to the diff action so the user
  2139       can see the coloured difference more easily. Thanks to Tobias Polzin.
  2140 
  2141   Other changes: =============================================================
  2142     * HINT: please copy a new version of your server script from the wiki/server/
  2143       directory and edit it to match your setup.
  2144     * HINT: instead of "from MoinMoin.multiconfig import DefaultConfig" you
  2145       need to use "from MoinMoin.config.multiconfig import DefaultConfig" now.
  2146       You need to change this in your wikiconfig.py or farmconfig.py file.
  2147       See MoinMoin/multiconfig.py for an alternative way if you can't do that.
  2148     * HINT: you need to change some imports (if you have them in your config):
  2149       Old: from MoinMoin.util.antispam import SecurityPolicy
  2150       New: from MoinMoin.security.antispam import SecurityPolicy
  2151       Old: from MoinMoin.util.autoadmin import SecurityPolicy
  2152       New: from MoinMoin.security.autoadmin import SecurityPolicy
  2153     * HINT: you need to change your auth stuff, the new way is:
  2154       from MoinMoin.auth import moin_login, moin_session
  2155       from MoinMoin.auth.http import http
  2156       auth = [http, moin_login, moin_session]
  2157       Do it in a similar way for other auth methods.
  2158     * HINT: you need to change your url_prefix setting in 2 ways:
  2159       1. The setting is now called url_prefix_static (to make it more clear
  2160          that we mean the static stuff, not the wiki script url).
  2161       2. The strongly recommended (and default) value of it is '/moin_static160'
  2162          for moin version 1.6.0 (and will be ...161 for moin 1.6.1). It is
  2163          possible and recommended to use a very long cache lifetime for static
  2164          stuff now (Expires: access plus 1 year), because we require to change
  2165          the URL of static stuff when the static stuff changes (e.g. on a
  2166          version upgrade of moin) to avoid problems with stale cache content.
  2167          Your moin will be faster with lower load and traffic because of this.
  2168          For standalone server, we use 1 year expiry for static stuff now.
  2169          For Apache, Lighttpd and other "external" servers, you have to care
  2170          for configuring them to use a long expiry and change url_prefix_static
  2171          related configuration on upgrade.
  2172       HINT: if you run standalone or Twisted server, the easiest way to get a
  2173             working configuration (with server configuration matching wiki
  2174             configuration) is to NOT set url_prefix_static at all. Moin will
  2175             use matching configuration defaults in this case.
  2176     * url_prefix_action ['action'] was introduced for lowering load and traffic
  2177       caused by searchengine crawlers. Up to now, crawlers where causing a high
  2178       load in internet moin wikis because they tried to get about everything,
  2179       including all actions linked from the user interface.
  2180       Known crawlers only get 403 for most actions, but nevertheless they first
  2181       tried. There was no means keeping them away from actions due to the rather
  2182       braindead robots.txt standard. You can only disallow pathes there, but
  2183       moin's actions were querystring based, not path based (this would need
  2184       regex support in robots.txt, but there is no such thing).
  2185       This changed now. Moin is able to generate action URLs you can handle in
  2186       robots.txt, like /action/info/PageName?action=info. So if you don't want
  2187       bots triggering actions, just disallow /action/ there. Keep in mind that
  2188       attachments are handled by /action/AttachFile, so if you want attached
  2189       files and pictures indexed by search engine, don't disallow
  2190       /action/AttachFile/ in your robots.txt. In order to use this feature,
  2191       set url_prefix_action in your wikiconfig to e.g. "action".
  2192     * We use (again) the same browser compatibility check as FCKeditor uses
  2193       internally, too. So if GUI editor invocation is broken due to browser
  2194       compatibility issues or a wrong browser version check, please file a bug
  2195       at FCKeditor development or browser development.
  2196     * HINT: We removed Lupy based indexed search code. If you were brave enough
  2197       to use cfg.lupy_search, you maybe want to try cfg.xapian_search instead.
  2198 
  2199   Developer notes: ===========================================================
  2200     * We moved the IE hacks to theme/css/msie.css that gets included after all
  2201       other css files (but before the user css file) using a conditional
  2202       comment with "if IE", so it gets only loaded for MSIE (no matter which
  2203       version). The file has some standard css inside (evaluated on all MSIE
  2204       versions) and some * html hacks that only IE < 7 will read.
  2205       HINT: if you use custom themes, you want to update them in the same way.
  2206     * autofilters for databrowser widget. Thanks to Johannes Berg for the patch.
  2207     * changed formatter.attachment_link call (it is now more flexible,
  2208       because you can render the stuff between link start and link end yourself)
  2209     * Page.url() does not escape any more. You have to use wikiutil.escape()
  2210       yourself if you want to write the URL to HTML and it contains e.g. &.
  2211     * The testing wikiconfig moved to tests/wikiconfig.py, the testing wiki
  2212       is now created in tests/wiki/...
  2213     * HINT: Killed "processors" (finally), formatter method changed to:
  2214       formatter.parser(parsername, lines)
  2215     * Refactored some actions to use ActionBase base class.
  2216     * Moved "test" action from wikiaction to MoinMoin/action/
  2217       (and use ActionBase).
  2218     * Moved MoinMoin/config.py to MoinMoin/config/__init__.py.
  2219     * Moved MoinMoin/multiconfig.py to MoinMoin/config/multiconfig.py.
  2220     * Moved "SystemInfo" macro from wikimacro to MoinMoin/macro/.
  2221     * Moved wikiaction.py stuff to MoinMoin/action/__init__.py.
  2222     * Moved wikimacro.py stuff to MoinMoin/macro/__init__.py.
  2223     * Moved wikirpc.py stuff to MoinMoin/xmlrpc/__init__.py.
  2224     * Moved wikitest.py stuff to action/test.py (only used from there).
  2225     * Moved formatter/base.py to formatter/__init__.py (FormatterBase).
  2226     * Moved util/ParserBase.py to parser/ParserBase.py.
  2227     * Moved / splitted request.py into MoinMoin/request/*.
  2228       Most stuff will be broken, please help fixing it (usually some imports
  2229       will be missing and the adaptor script will need a change maybe):
  2230       Tested successfully: CGI, CLI, STANDALONE, FCGI, TWISTED
  2231     * Moved security.py to security/__init__.py.
  2232     * Moved wikiacl.py to security/__init__.py.
  2233     * Moved logfile/logfile.py to logfile/__init__.py.
  2234     * Moved mailimport.py to mail/mailimport.py.
  2235     * Moved util/mail.py to mail/sendmail.py.
  2236     * Moved auth.py to auth/__init__.py.
  2237       Moved util/sessionParser.py to auth/_PHPsessionParser.py.
  2238       teared auth code into single modules under auth/* - moin_session handling
  2239       and the builting moin_login method are in auth/__init__.py.
  2240     * Added wikiutil.MimeType class (works internally with sanitized mime
  2241       types because the official ones suck).
  2242     * Renamed parsers to module names representing sane mimetypes, e.g.:
  2243       parser.wiki -> parser.text_moin_wiki
  2244     * Added thread_monitor debugging aid. It can be activated using:
  2245       from MoinMoin.util import thread_monitor; thread_monitor.activate_hook()
  2246       and then triggered by requesting URL ...?action=thread_monitor - please
  2247       be aware that monitoring threads has a big performance impact on its own,
  2248       so you only want to temporarily enable this for debugging.
  2249       By default, it dumps its output to the data_dir as tm_<timestamp>.log,
  2250       you can change this at bottom of action/thread_monitor.py if you want to
  2251       see output in your browser.
  2252     * Introduced scope parameter to CacheEntry() - if you specify 'farm', it
  2253       will cache into a common directory for all wikis in the same farm, if you
  2254       specify 'wiki', it will use a cache directory per wiki and if you specify
  2255       'item', it will use a cache directory per item (== per page).
  2256       Creating a CacheEntry without explicit scope is DEPRECATED.
  2257     * Smileys moved from MoinMoin.config to MoinMoin.theme.
  2258     * Removed all _ magic in URLs and filenames.
  2259     * request.action now has the action requested, default: 'show'.
  2260     * Cleaned up duplicated http_headers code and DEPRECATED this function
  2261       call (it was sometimes confused with setHttpHeaders call) - it will
  2262       vanish with moin 1.7, so please fix your custom plugins!
  2263       The replacement is:
  2264           request.emit_http_headers(more_headers=[])
  2265       This call pre-processes the headers list (encoding from unicode, making
  2266       sure that there is exactly ONE content-type header, etc.) and then
  2267       calls a server specific helper _emit_http_headers to emit it.
  2268       Tested successfully: CGI, STANDALONE, FCGI, TWISTED
  2269     * setResponseCode request method DEPRECATED (it only worked for Twisted
  2270       anyway), just use emit_http_headers and include a Status: XXX header.
  2271       Method will vanish with moin 1.7.
  2272     * cfg.url_prefix is DEPRECATED, please use cfg.url_prefix_static.
  2273     * d['title_link'] is not supported any more. You can easily make that link
  2274       on your own in your theme, see example in MoinMoin/theme/__init__.py,
  2275       function "title".
  2276     * There is a new Page method called Page.get_raw_body_str that returns
  2277       the encoded page body. This is useful if you just deal with byte data
  2278       (e.g. while generating binary diffs).
  2279     * The TagStore/PickleTagStore system is used to store the syncronisation tags.
  2280     * XMLRPC functions may return Fault instances from now on
  2281     * Moin got multicall support, including a module that makes it usable on the
  2282       client-side without requiring Python 2.4
  2283     * Added no_magic to text_html formatter to disable tag autoclosing.
  2284     * MOIN_DEBUG can be set in the environment to let MoinMoin ignore exceptions
  2285       that would lead to a traceback in the browser. Thanks to Raphael Bossek.
  2286     * There is a new MoinMoin.Page.ItemCache class now with automatic cache
  2287       invalidation based on global edit-log. We currently use it to cache page
  2288       acls, speedup Page.get_rev and reading the page local edit-log.
  2289     * Added wikiutil.renderText parse and format raw wiki markup with all page elements.
  2290     * The user file format has changed, old files will be read correctly but
  2291       will silently be upgraded to the new format so old versions will not
  2292       read the new files correctly (this only affects 'subscribed_pages' and
  2293       'quicklinks' which will be lost when downgrading.)
  2294 
  2295 
  2296 Version 1.5.8:
  2297   New features:
  2298     * Added timing.log to help performance debugging. Use cfg.log_timing = True
  2299       to update <data_dir>/timing.log (default is False, meaning no logging).
  2300 
  2301       Example log entries:

  2310       PID: the process ID of the moin process
  2311       Timing: when action starts, it will be "vvv"
  2312               when it ends, it logs the total time it needed for execution
  2313       Flag (some are only logged at end of action):
  2314       +   Page exists
  2315       -   Page does not exist
  2316       B   user agent was recognized as bot / spider
  2317       !x! Action took rather long (the higher the x, the longer it took - this
  2318           makes it easy to grep for problematic stuff).
  2319       Action: action name (None is when no action was specified, moin assumes
  2320               "show" for that case)
  2321       URL: the requested URL
  2322 
  2323       For more information about tuning your moin setup, see:
  2324       http://moinmoin.wikiwikiweb.de/PerformanceTuning
  2325     * Added support for ircs, webcal, xmpp, ed2k and rootz protocols - we
  2326       moved all protocols to config.url_schemas, so this is not empty any more.
  2327       It is possible to use these protocols now on wiki pages and in the
  2328       navi_bar. We just generate the URLs, it is up to your browser what it
  2329       does when clicking on those links.
  2330     * cfg.traceback_show (default: 1) can be used to disable showing tracebacks.
  2331       cfg.traceback_log_dir (default: None) can be used to set a directory
  2332       that is used to dump traceback files to. Your users will get a notice to
  2333       which (random) file in that directory the traceback was been written.
  2334       NOTE: while you can feel free to set traceback_show = 0 and
  2335       traceback_log_dir = None, we will also feel free to reject bug reports
  2336       when you (or your site's users) don't give us enough information (like a
  2337       traceback file) to debug the problem. If you set traceback_show = 0,
  2338       we recommend pointing traceback_log_dir to a directory with reasonable
  2339       free space and putting a page onto your wiki that describes who has to
  2340       get contacted (usually the wiki server admin) in case a traceback happens.
  2341       The admin can then locate the traceback file and submit it to moin
  2342       development, if the bug is not already known (see MoinMoin:MoinMoinBugs).
  2343       Of course we will also need all the other details of a bug report, not
  2344       only the traceback file.
  2345 
  2346   Other changes:
  2347     * Updated spider agents list.
  2348     * Reduce bot/spider cpu usage for SystemInfo, OrphanedPages, WantedPages,
  2349       PageHits, PageSize, WordIndex macros (we just return nothing for bots).
  2350 
  2351   Bugfixes:
  2352     * XSS fixes, see http://secunia.com/advisories/24138/ (item 1 and 2).
  2353     * ACL security fixes:
  2354       * MonthCalendar respects ACLs of day pages now.
  2355       * Check the ACL for the rst markup include directive.
  2356     * Fixed cleaning of edit comments (control chars in there could damage
  2357       edit-log).
  2358     * Fixed in-process caching of antispam patterns (didn't update the cache
  2359       for multi-process, persistent servers).
  2360     * Correct encoding/decoding for surge-log data, fixes leftover
  2361       surge-logXXXXXXX.tmp files in data/cache/surgeprotect.
  2362     * Fixed mode of cache files (mkstemp creates them with 0600 mode).
  2363     * Symbolic entities with numbers (like &sup2;) did not work, fixed.
  2364     * We open data/error.log earlier now and we also use it for FastCGI.
  2365     * Fixed unicode cfg.page_group_regex.
  2366     * Fixed moin.spec to use english date format.
  2367     * GUI converter: fixed conversion of relative wiki links.
  2368     * Fixed NewPage macro button label to not be formatted as wiki text.
  2369 
  2370 Version 1.5.7:
  2371   New features:
  2372     * added url_prefix_local which is used for stuff that must be loaded from
  2373       same site as the wiki engine (e.g. FCKeditor GUI editor applet), while
  2374       url_prefix can be a remote server serving the static files (css/img).
  2375       If not set (or set to None), url_prefix_local will default to the value
  2376       of url_prefix.
  2377     * We save some CPU and disk I/O by having EditTemplates and LikePages macro
  2378       (both used on MissingPage) check whether the requesting entity was
  2379       identified as a spider (e.g. search engine bot) and do nothing in that
  2380       case. Normal users won't see any difference.
  2381     * For AttachFile, you can now choose to overwrite existing files of same
  2382       name (nice for updating files).
  2383 
  2384   Bugfixes:
  2385     * XSS Fixes:
  2386       * fixed unescaped page info display.
  2387       * fixed unescaped page name display in AttachFile, RenamePage and
  2388         LocalSiteMap actions
  2389     * WantedPages listed existing pages that are not readable for the user,
  2390       but are linked from pages that ARE readable for the user (so this is NOT
  2391       a privacy/security issue). We now don't list those pages any more as it
  2392       is pointless/confusing, the user can't read or edit there anyway.
  2393     * MoinMoin: href="http://moinmo.in/MoinMoinBugs/TableOfContentsUsesNonExistingIncludeLinks">MoinMoinBugs/TableOfContentsUsesNonExistingIncludeLinks
  2394     * MoinMoin: href="http://moinmo.in/MoinMoinBugs/ActionsExcludedTriggerError">MoinMoinBugs/ActionsExcludedTriggerError
  2395     * GUI editor/converter:
  2396       * ignore <col>/<colgroup>/<meta> elements
  2397       * support <a> within blockquote
  2398     * Remove generated=... attribute from pagelink html output (this attr is
  2399       for internal use only). w3c validator is now happier again.
  2400     * Fixed css class "userpref" (not: "userprefs") of the Login form.
  2401     * Fixed the version number check in the xslt parser for 4suite >= 1.0.
  2402     * We reset the umask to the wanted value every request. This should fix
  2403       wrong file modes when used with Twisted (twistd uses a hardcoded 0077
  2404       umask in daemonize()).
  2405     * Avoid trouble when saving pages with antispam function when MoinMaster
  2406       wiki is having troubles (catch xmlrpc Fault).
  2407 
  2408   Other changes:
  2409     * Standalone server does not do reverse DNS lookups any more (this is a
  2410       standard feature of BaseHTTPServer stdlib module, but we override this
  2411       now and just print the IP).
  2412     * We moved the IE hacks to theme/css/msie.css that gets included after all
  2413       other css files (but before the user css file) using a conditional
  2414       comment with "if IE", so it gets only loaded for MSIE (no matter which
  2415       version). The file has some standard css inside (evaluated on all MSIE
  2416       versions) and some * html hacks that only IE < 7 will read.
  2417       HINT: if you use custom themes, you want to update them in the same way.
  2418     * Improved ldap auth:
  2419       * cfg.ldap_name_attribute was removed because of new cfg.ldap_filter.
  2420         If you had ldap_name_attribute = 'sAMAccountName' before, just use
  2421         ldap_filter = '(sAMAccountName=%(username)s)' now.
  2422       * New cfg.ldap_filter used for the ldap filter string used in the ldap
  2423         search instead of the rather limited, partly hardcoded filter we used
  2424         before. This is much more flexible:
  2425         ldap_filter = '(sAMAccountName=%(username)s)'
  2426         You can also do more complex filtering expressions like:
  2427         '(&(cn=%(username)s)(memberOf=CN=WikiUsers,OU=Groups,DC=example,DC=org))'
  2428       * Added some processing to filter out result entries with dn == None.
  2429       * We set REFERRALS option to 0 before initializing the ldap server
  2430         connection (this seems to be needed for Active Directory servers).
  2431       * We support self-signed ssl certs for ldaps - completely untested.
  2432       * New cfg.ldap_surname_attribute (usually 'sn'), was hardcoded before.
  2433       * New cfg.ldap_givenname_attribute (usually 'givenName'), hardcoded before.
  2434       * New cfg.ldap_aliasname_attribute (usually 'displayName') - if this
  2435         attribute is not there or empty (in the results of the ldap lookup for
  2436         the user), we just make up the aliasname from surname and givenname
  2437         attribute.
  2438       * We only request the attributes we need from ldap (was: all attrs).
  2439       * We deny user login (and break out of auth chain) for the following cases:
  2440         * if a user is not found by ldap lookup
  2441         * if we find more than one matching entry
  2442         * if the password is empty or incorrect
  2443         * if some exception happens
  2444       * Please note that there is an updated ldap sample config in directory
  2445         wiki/config/more_samples/.
  2446       * Added experimental LDAP SSL/TLS support (untested, please help testing),
  2447         see also the sample config.
  2448     * Work around a IE7 rendering problem with long pages getting more and
  2449       more narrow. We just applied the same "fix" as we used for IE6, using
  2450       "display: none" for span.anchor for IE browsers.
  2451     * RSS feed related:
  2452       * We used to emit a <link> tag for the action=rss_rc RSS feed on any
  2453         page. This was changed, we now emit that link only on RecentChanges and
  2454         the current user's language translation of RecentChanges.
  2455         This was changed because Google Toolbar requests the RSS feed linked
  2456         by such a link tag every time it sees one. Thus, if you used the wiki
  2457         normally, it requested the RSS feed every few seconds and caused
  2458         problems due to surge protection kicking in because of that.
  2459       * HINT for custom theme users: if your theme code calls
  2460         rsslink(), then you need to change that to rsslink(d) for 1.5.7+.
  2461 
  2462 
  2463 Version 1.5.6:
  2464   A general security notice:
  2465       Check your Python version, there was a buffer overflow issue in Python
  2466       recently! Details: http://moinmoin.wikiwikiweb.de/PythonUnicodeEscapeBug
  2467 
  2468   Bugfixes:
  2469     * Fix AttributeError traceback with Standalone server (if_modified_since)
  2470     * Fix AttachFile "304 not modified" and redirect status code for Twisted
  2471     * http auth: we now decode username and password to unicode (using
  2472       config.charset == utf-8). Same for SSL client cert auth and CN.
  2473     * Avoid infinite recursion in Page.parsePageLinks.
  2474     * Fixed standalone server failing to shutdown if interface == "".
  2475     * Now MoinMoin does not think anymore that every page links to various user
  2476       homepages.
  2477     * Made the irssi parser more tolerant (Thanks to "TheAnarcat").
  2478     * Now multiple formatters can be used per request, the send_page code was
  2479       not reentrant to this regard. Fixes "empty" search results.
  2480     * Fixed problem with "=" in ImageLink macro links.
  2481     * Not a moin bug, but a silly stdlib os.tempnam function made trouble to
  2482       some people because it lets you override the path given in the code
  2483       by setting the environment variable TMP(DIR). We now use a different
  2484       function to avoid renaming trouble when TMP(DIR) points to a different
  2485       file system.
  2486     * Fixed antispam update on every save (Thanks to "TheAnarcat").
  2487     * GUI converter: don't throw away rowclass for tables.
  2488     * GUI editor formatter: allow height for table cells.
  2489     * GUI editor formatter: comment texts are output using the formatter now. 
  2490 
  2491   New features:
  2492     * Mail notifications contain a link to the diff action so the user
  2493       can see the coloured difference more easily. Thanks to Tobias Polzin.
  2494     * FeatureRequests/MoveAttachments - you can move attachments from one
  2495       page to another (and also rename the attachment at the same time).
  2496       Thanks to Reimar Bauer.
  2497     * Added support for linking to attachment: and inline: URLs with ImageLink.
  2498     * Added UNIX socket support for FastCGI, just set the port to some (socket)
  2499       filename. Details see: MoinMoin:FeatureRequests/FastCgiUnixSocket
  2500     * [[Attachlist(pagename,mimetype)]] lists attachments of pagename (default:
  2501       current page) with optional mimetype restriction (default: all).
  2502       Thanks to Reimar Bauer.
  2503 
  2504   Other changes:
  2505     * Minor performance improvements (might be noticeable if you have many
  2506       custom navi_bar entries and high server load).
  2507     * Avoid usage of no-cache because it breaks attachment download on IE6.
  2508       This is a IE bug, not a moin bug.
  2509     * Added XHTML to the unsafe list.
  2510     * Changed the rst parser to be compatible to the new docutils interface
  2511       for directives.
  2512     * Updated EmbedObject macro.
  2513 
  2514 
  2515 Version 1.5.5a:
  2516   Bugfixes:
  2517     * fixed ticket creation to only use constant values
  2518 
  2519 Version 1.5.5:
  2520   HINT: read docs/README.migration.
  2521   HINT: there was NO change in the underlay/ pages since 1.5.4.
  2522   HINT: If you experience problems with the reStructured Text (rst) parser,
  2523         please downgrade docutils to "0.4" because there were major interface
  2524         breaking API refactorings on the docutils trunk.
  2525 
  2526   Bugfixes:
  2527     * GUI editor fixes:
  2528       * Fixed MoinMoinBugs/GuiEditorModifiesInterwikiPreferred.
  2529       * Fixed MoinMoinBugs/TableAlignmentProbsWithGUI.
  2530     * Not a moin bug, but it severely annoyed IE users and also was less
  2531       comfortable for users of other browser: since about 1.5.4, we served
  2532       attachments with Content-Disposition: attachment - so that the user has
  2533       to save them to disk. This was to fix a possible XSS attack using attached
  2534       HTML files with Javascript inside for stealing your moin cookie or doing
  2535       other nasty things. We improved this by using different behaviour depending
  2536       on the potential danger the attached file has when served inline:
  2537       mimetypes_xss_protect = ['text/html', 'application/x-shockwave-flash', ]
  2538       This is the default value. If you know more dangerous stuff, please just
  2539       add the mimetypes there to protect your users and file a bug report
  2540       telling us what we missed.
  2541     * Fixed MoinMoinBugs/ReStructuredTextRelativeLinksBroken, thanks to Stefan
  2542       Merten.
  2543     * Make tickets used for some actions more safe.
  2544 
  2545   New features:
  2546     * edit_ticketing [True] - we protect page save by a ticket (same stuff we
  2547       already use for DeletePage and RenamePage action).
  2548       NOTE: If you don't use your browser for editing, but some tool like
  2549             "editmoin" or "MoinMoin plugin for jEdit", you'll need an update
  2550             of them supporting the ticket.
  2551             Alternatively, you can use edit_ticketing = False setting - this
  2552             is not recommended for internet wikis as it will make spamming them
  2553             easier.
  2554     * If we detect some spammer, we kick him out by triggering surge protection
  2555       (if surge protection is not disabled).
  2556 
  2557 Version 1.5.5rc1:
  2558   Bugfixes:
  2559     * Fixed MoinMoinBugs/XmlRpcBrokenForFastCgi - thanks to Johannes Berg.
  2560     * Fixed gui editor converter confusing of `` and {{{}}} markup.
  2561     * Fixed emission of HTTP headers (esp. Vary: Cache-Control:).
  2562     * Fixed a bad crash that happens (on ANY page!) when you put a *Dict
  2563       page's name as a member into a *Group page.
  2564     * Fix MyPages action title to use an unformatted string.
  2565     * Fix double quoted-printable encoding in generated emails (note: this is
  2566       not a moin bug - this just works around bugs in python stdlib).
  2567     * Fix mode of drawing files (use config.umask).
  2568     * Fix trouble with /?action= urls by dropping getPageNameFromQueryString
  2569       code. 
  2570     * Fixed sre unpickle issues seen on some machines by avoiding to pickle
  2571       the regex.
  2572     * Fix Clock code, add more timers.
  2573     * Worked around FastCGI problem on Lighttpd: empty lines in the error log.
  2574     * Fix (add) locking for caching's .remove() call, small fixes to lock code.
  2575     * Print error message when --target-dir=path is missing from moin export
  2576       dump command.
  2577 
  2578   New features:
  2579     * Added support for "304 not modified" response header for AttachFile get
  2580       and rss_rc actions - faster, less traffic, less load.
  2581     * Limit rss with full diffs to 5 items.
  2582     * Allow surge_action_limits = None to disable surge protection.
  2583     * moin.fcg improved - if you use FastCGI, you must use the new file:
  2584       * can self-terminate after some number of requests (default: -1, this
  2585         means "unlimited lifetime")
  2586       * the count of created threads is limited now (default: 5), you can use
  2587         1 to use non-threaded operation.
  2588       * configurable socket.listen() backlog (default: 5)
  2589     * Added indonesian i18n (id).
  2590     * Some measures against spammers trying to brute force their spam into moin.
  2591     * EmbedObject macro: added mov, mpg and midi support
  2592     * moin ... export dump --target-dir=PATH --page=PAGENAME_REGEX
  2593       You must specify --target-dir (where dump will write the html files to)
  2594       and you may specify --page and either a page name or a regex used to
  2595       match all pages you want to export. Default is to export all pages.
  2596 
  2597   Other changes:
  2598     * Tuning:
  2599       * more efficient locking code on POSIX platforms, we do much less I/O
  2600         for locking now
  2601       * removed most chmod calls in favour of a single os.umask call
  2602     * Improved Python 2.5 compatibility. Note: if you think that MoinMoin
  2603       is using too much RAM, you might want to look at Python 2.5 because
  2604       of its improved memory management.
  2605     * Throw away SAVE comments longer than 200 chars (you can't enter those by
  2606       the user interface, so only spammer using automatic POSTs do them).
  2607     * Updated spider user agent list.
  2608     * BadContent and LocalBadContent now get noindex,nofollow robots header,
  2609       same as POSTs.
  2610     * Standalone opens it logfile unbuffered from now on, thanks to
  2611       Carsten Grohmann.
  2612     * Avoid trouble when request.write() data contains None, just skip it -
  2613       thanks to Juergen Hermann.
  2614     * Instead of showing a ConfigurationError, moin now emits "404 Not found"
  2615       http headers and a hint about what could be wrong. This won't fill up
  2616       your logs just because of typos and spiders still trying old URLs.
  2617 
  2618  
  2619 Version 1.5.4:
  2620     HINT: read docs/README.migration.
  2621 Version 1.5.4-current:
  2622     * increased maxlength of some input fields from 80 to 200
  2623 
  2624 Version 1.5.current:
  2625   Developer notes:
  2626     * We switched to Mercurial SCM, see here for more infos:
  2627       http://moinmoin.wikiwikiweb.de/MoinDev/MercurialGuide
  2628 
  2629   Bugfixes:
  2630     * fix MonthCalendar macro for non-ASCII pagenames (thanks to Jonas Smedegaard)
  2631     * remove 'search' and 'google' from bot user agent list and add some more
  2632       specific terms
  2633     * Fix the forgotten password email login URL and also properly encode the
  2634       email body. Thanks to Robin Dunn for the patch.
  2635     * Applied a patch by Matthew Gilbert for increased compatiblity with
  2636       latest docutils.
  2637 
  2638 
  2639 Version 1.5.3:
  2640   New Features:
  2641     * Added CSS classes for TableOfContents macro.
  2642 
  2643   Bug Fixes:
  2644     * GUI editor / GUI editor converter:
  2645       * Fixed missing GUI editor link in edit bar.
  2646       * Fixed table/row/cell style spaces.
  2647       * Changed <p> generation for macros.
  2648       * Fixed handling of subpages.
  2649       * Fixed processing of complex list elements (thanks to Craig Markwardt).
  2650       * Fixed processing of html \n (thanks to Craig Markwardt).
  2651       * Fixed joining of comment lines with text below them.
  2652       * Fixed table height attribute crash.
  2653     * Fixed sslclientcert auth.
  2654     * Added some missing files to i18n processing, translatable strings more
  2655       complete now.
  2656     * Change <p> generation from self-closing (<p />) to auto-closing (only
  2657       emit <p>, let browser find place for </p>).
  2658     * Fix eating of newline before tables.
  2659     * Fixed incorrect login hint for not logged-in users trying a disallowed
  2660       action.
  2661     * Fixed nasty missing or double </a> formatter bug (mostly happening when
  2662       user has enabled questionmarks for nonexisting pages).
  2663 
  2664   Other Changes:
  2665     * We catch and ignore html to wiki conversion errors in case of hitting
  2666       the cancel button, so you can get out of the error screen.
  2667 
  2668 Version 1.5.3-rc2:
  2669   New Features:
  2670     * Modified SystemInfo macro to give human readable units and disk usage
  2671     * cfg.editor_quickhelp makes the quick help below the editor configurable
  2672       (at least as far as the default_markup is concerned). If set to None,
  2673       it doesn't display any quickhelp. Thanks to Seth Falcon for the patch.
  2674 
  2675   Bugfixes:
  2676     * Fixed double class attribute for nonexistent links
  2677     * Fixed double </a> with qm_noexist option
  2678     * Fixed table xxx="yyy" style attribute parsing
  2679     * If not (editor_force and editor_default == 'text') then display GUI mode
  2680       switch button (this is only a partial fix, but enough to deny the GUI
  2681       mode to your users completely)
  2682     * Fixed XSS issue which could lead to cookie theft etc.
  2683     * Fixed definition list "same level" indenting.
  2684     * Fixed pagename in log for PackagePages action.
  2685     * Made <p> self-closing and line-anchors more well-behaved, thanks to
  2686       Martin Wilck for the patch. I didn't apply the <ol> patch, because this
  2687       is no real problem, just a problem of a bad standard.
  2688     * Fixed gui editor *bgcolor crash.
  2689     * Support/Fix tableclass attr with gui editor.
  2690 
  2691   Other changes:
  2692     * Moved back UserPreferences action link from menu to top of page (renaming
  2693       it to "Preferences"), added "Cancel" button to make it possible to return
  2694       to the previous page without saving preferences.
  2695     * Removed formatter.url "attrs" keyword arg that took premade html, we use
  2696       separate kw args per attribute now.
  2697     * Moved broken tests to MoinMoin/_tests/broken (= disabling them).
  2698       All "active" tests run ok now.
  2699       If you want to compare, I included the output of this test run:
  2700       $ make test >tests/make_test.out
  2701 
  2702  
  2703 Version 1.5.3-rc1:
  2704 
  2705   New features:
  2706     * HINT: please read README.migration
  2707     * Login and Logout are actions now, therefore you stay on the page where
  2708       you were before.
  2709     * UserPreferences is also an action now and moved from top border (in
  2710       modern theme) to the "more actions" dropdown menu. You also stay on the
  2711       same page.
  2712     * There is also a [[Login]] macro now. You can put it on any page you want
  2713       and if the user is not logged in, it renders the login form. If the user
  2714       is logged in, it doesn't render anything.
  2715     * We check cfg.superuser to be a list of user names (as documented) and
  2716       deny superuser access if it is not. This avoids security issues by
  2717       wrong configuration.
  2718     * auth methods changed:
  2719       HINT: if you wrote own auth methods, please change them as you see in
  2720             MoinMoin/auth.py and test them again before relying on them.
  2721       * now get a user_obj kw argument that is either a user object returned
  2722         from a previous auth method or None (if no user has been made up yet).
  2723         The auth method should either return a user object (if it has
  2724         determined one) or what it got as user_obj (being "passive") or None
  2725         (if it wants to "veto" some user even if a previous method already has
  2726         made up some user object).
  2727       * return value of continue_flag is now True in most cases (except if
  2728         it wants to "veto" and abort).
  2729       * moin_cookie auth method now logs out a user by deleting the cookie and
  2730         setting user_obj.valid = 0. This makes it possible to still get the
  2731         user's name in subsequent auth method calls within the same request.
  2732       * added ldap_login and smb_mount auth methods, see MoinMoin/auth.py and
  2733         wiki/config/more_samples/ldap_smb_farmconfig.py
  2734     * MonthCalendar now takes an additional argument for specifying a template
  2735       to use to directly invoke the page editor when clicking on non-existing
  2736       day pages.
  2737     * Added ImageLink macro. Thanks to Jeff Kunce, Marcin Zalewski, Reimar
  2738       Bauer and Chong-Dae Park for working on it.
  2739     * Lupy stuff (still experimental, partly broken and disabled by default):
  2740       * Attachment search using lupy (lupy_search = 1 in your config)
  2741         Title search will also search attachment filenames.
  2742         Full text search will also search attachment contents.
  2743       * Indexing filter plugins, see MoinMoin:FiltersForIndexing
  2744         Some filters depend on external converters that might not be available
  2745         for any platform (see Depends: line in filter plugin).
  2746         Feel free to contribute more filter plugins, especially if you wrote
  2747         some nice platform independant filter in Python for some popular file
  2748         format! Filters implemented so far (depending on):
  2749         MS Word, RTF, MS Excel (antiword, catdoc)
  2750         PDF (pdftotext)
  2751         OpenOffice.org XML based data formats (-)
  2752         XML, HTML (-)
  2753         text/* (-)
  2754         JPEG's EXIF data (-)
  2755         Binary generic (-)
  2756       * As you might know, Lupy is "retired" (that means it isn't developped
  2757         by its authors any more). We are currently evaluating Xapian as new
  2758         indexing search engine in moin.
  2759         If we succeed, we will replace Lupy stuff by some Xapian interface
  2760         code in moin.
  2761         But: the filters will likely stay, as we also need them with Xapian.
  2762     
  2763     * A new MoinMoin script interface was introduced:
  2764       
  2765       Syntax: moin [options] <cmdmodule> <cmdname> [options]
  2766       
  2767       For example:
  2768       moin --config-dir=/my/cfgdir --wiki-url=wiki.example.org/ \
  2769            export dump --page=WikiSandBox
  2770       
  2771       This will call the "moin" script, which will use the --config-dir and
  2772       --wiki-url options to initialize, then it will go to MoinMoin.script
  2773       module, import the export.dump module from there and run it, providing
  2774       the additional --page value to it.
  2775 
  2776       The old scripts that have not been migrated to this new interface can
  2777       still be found in MoinMoin/script/old/ - including the old migration
  2778       scripts.
  2779     * moin ... account create --name=JoeDoe --email=joe@doe.org
  2780     * moin ... account disable --name=JoeDoe
  2781     * moin ... acount check     <-- this is what usercheck script was before
  2782     * moin ... maint cleancache <-- this is what cachecleaner script was
  2783     * moin ... maint cleanpage  <-- this is what pagescleaner script was
  2784 
  2785   Bugfixes:
  2786     * cookie_lifetime didn't work comfortable for low values. The cookie was
  2787       created once on login and never updated afterwards. So you got logged
  2788       out cookie_lifetime hours later, no matter whether you were active at
  2789       that time or not. This has been changed, we update the cookie expiry now
  2790       on every request, so it will expire cookie_lifetime after your last
  2791       request (not after login).
  2792     * Fixed logout problems when using cfg.cookie_path.
  2793     * Fixed cookie_path for root url wikis.
  2794     * Lupy search now behaves a bit less funky. Still no guarantees...
  2795     * We lowered the twisted server timeout to 2 minutes now (was: 10) because
  2796       it just used up too many files (open TCP connections until it timeouts)
  2797       on our farm.
  2798     * The algorithm used for processing the farmconfig.wikis list was changed
  2799       to work for big farms (>= 50 wikis), too. This works around the python
  2800       "re" module limitation of having a maximum of 100 named groups in a RE.
  2801     * Fixed a TypeError which occurred for formatters that dislike None values.
  2802       (cf. http://moinmoin.wikiwikiweb.de/MoinMoinBugs/PythonErrorEditingFrontPage)
  2803     * Fixed GUI editor converter error for https:... image URLs.
  2804     * ThemeBase (use by modern/rightsidebar): removed duplicate AttachFile from
  2805       actions menu (we already have it in editbar).
  2806     * Speedup group/dicts scanning for persistent servers.
  2807     * Implemented HEAD requests for standalone server, this should fix some of
  2808       the strange effects happening when using "Save as" on attachments.
  2809     * Not a moin bug, but rather a workaround for non-standard non-ASCII DNS
  2810       hostnames: we just use the IP instead of crashing now.
  2811     * Spurious cyclic usage error in i18n fixed.
  2812     * Fixed antispam for python 2.5a xmlrpclib.
  2813     * I18n for linenumber toggle in listings.
  2814     * All action menu entries are translatable now.
  2815 
  2816   Other:
  2817     * Added css classes for the rst admonitions. Thanks to TiagoMacambira!
  2818 
  2819 Version 1.5.2:
  2820 
  2821   New features:
  2822     * Added FullSearchCached macro which is statically cached.
  2823       Use it if you do not depend on fresh search results but prefer raw speed.
  2824     * Added surge protection, see HelpOnConfiguration/SurgeProtection.
  2825     * Allow hex and symbolic entities.
  2826     * If there is a user with empty password, we just generate a random one
  2827       when he requests it getting sent by mail. Thanks to Reimar Bauer.
  2828     * The superuser now can switch to another user using UserPreferences -
  2829       nice to help your users when they forgot their password or need other
  2830       help. You need to logout/relogin to use your own userid afterwards.
  2831       This function only works correctly if you use moin_cookie authentication.
  2832       Thanks to Reimar Bauer.
  2833     * Add new markup for bulletless lists: just use a "." instead of "*".
  2834 
  2835   Other changes:
  2836     * Added "voyager" to bot useragent list.
  2837     * Added locking for caching subsystem.
  2838     * Deron Meranda's formatter API cleanup.
  2839     * Added div and span to formatter API.
  2840     * Removed old unfinished form and export code.
  2841     * updated i18n
  2842 
  2843   Fixes:
  2844    * Fixed table attribute parsing.
  2845    * Fixed cookie handling wrt properties adherance.
  2846    * The new "." list markup makes it possible to have a bulletless list with
  2847      elements on the same level. Before this change and only using indentation
  2848      with blanks, that would get merged into a single paragraph.
  2849    * It is possible now to have multiple paragraphs in the same list element,
  2850      just leave an empty line in between the paragraphs.
  2851    * Fixed GAP processing for ordered lists.
  2852    * Fix text_gedit formatter's invalid list nesting.
  2853    * Fixed hr crash in blockquote (but needs more work).
  2854    * Fixed FootNote's formatter usage.
  2855    * Fixed rst's headline levels.
  2856    * Fixed MoinMoinBugs/WikiParserThinksItIsInsidePreWhenItIsNot
  2857    * Fixed MoinMoinBugs/ListItemGeneratedOutsideList
  2858    * Fixed that macros were followed by a wrong <p>.
  2859    * Added <blockquote> to the block elements in the text_html formatter,
  2860      so it does not close it erratically when you close a inner <p>.
  2861    * GUI editor converter now also accept http: urls without // (relative or
  2862      same server urls).
  2863    * Fixed the DocBook parser in cases where the pagename was non-ascii.
  2864    * Fixed MoinMoinBugs/ProcessInlineDontSupportUlElement
  2865 
  2866 
  2867 Version 1.5.1:
  2868 
  2869   Fixes:
  2870     * Fixed rst parser docutils version check
  2871     * Repaired attachment unzipping feature.
  2872     * Fixed the AddRevision command of the PackageInstaller.
  2873     * improved the migration scripts (used to migrate pre-1.3 wikis to 1.3+):
  2874       * do not crash on empty lines in event log
  2875       * fix edit log format for very old moin data (like 0.11)
  2876       * workaround for an ugly win32 operating system bug leading to wiki text
  2877         file mtime not matching edit logs timestamp values if there was some
  2878         timezone change since last edit (e.g. a daylight saving tz switch),
  2879         but differing 3600s.
  2880         This affected pre-1.3 moin wiki servers running on win32 OS only.
  2881         We now try to correct those inconsistencies in mig05 by fuzzy matching.
  2882     * fixed bracketed link scheme icon (css class)
  2883     * we included a modified copy of Python 2.4.2's copy.py as some previous
  2884       python versions seem to have problems (2.3.x, x < 5 and also 2.4[.0]),
  2885       see: http://moinmoin.wikiwikiweb.de/MoinMoinBugs/DeepCopyError
  2886       Our own copy.py was slightly modified to run on 2.3.x and 2.4.x.
  2887     * Fixed the problem of not being able to change the date/time format back
  2888       to "Default" (UserPreferences).
  2889     * We generate the GUI editor footer now the same way as the text editor
  2890       footer.
  2891     * Include a CSS workaround for yet another IE bug, see:
  2892       MoinMoinBugs:InternetExplorerPeekABooBugInRightSideBar
  2893     * classic theme: added GUI editor link
  2894     * classic theme: added pagename header to editor screen
  2895     * the "mail enabled" check now also checks whether mail_from is set
  2896 
  2897   Other changes:
  2898     * Updated FCKeditor to current CVS (2006-01-08 == 2.2+)
  2899     * Split up show_hosts into show_hosts and show_names
  2900     * attachment:file%20with%20spaces.txt in attachment list
  2901     * added support for file:// in GUI editor link dialogue, see also:
  2902       MoinMoin:FileLinks
  2903     * cfg.mail_smarthost now supports "server:port" syntax, the default port
  2904       is 25, of course.
  2905     * removed unused kwargs showpage/editable/form from wikiutil.send_footer
  2906     * updated i18n (translation texts, additional languages)
  2907     * removed interwiki:pagename from print view's top of page, added it to
  2908       the "lasted edited" line at bottom right.
  2909 
  2910 
  2911 Version 1.5.0:
  2912   HINT: 1.5.0 uses the same data/pages format as 1.3.x. The only thing you want
  2913         to check is whether the 1.5.x version you are upgrading to has NEW mig
  2914         scripts compared to the version you are running now (e.g. in 1.3.5 we
  2915         added some scripts that fixed some small problems).
  2916         See the MoinMoin/scripts/migration/ directory.
  2917         You must run every mig script in sequence and only ONCE ever.
  2918   Fixes:
  2919     * Fix <x=y> table attributes parsing. Thanks to Reimar Bauer.
  2920     * Fixed a few bugs in the reStructured text parser. Note that you
  2921       need to install docutils 0.3.10 or newer (snapshot from December 2005
  2922       or newer) to make reStructuring parsing work:
  2923      * Case preservation for anonymous links
  2924      * MoinMoin links get the appropriate CSS class
  2925      * Images do not get special CSS markup anymore
  2926      Thanks to Matthew Gilbert.
  2927     * Fixed a bug in the WSGI code which led to incorrect exception handling.
  2928     * Removed all nationality flags. They used to be used for indicating some
  2929       specific language (NOT nationality) and this was simply wrong and a bad
  2930       idea.
  2931     * Fixed some header rendering issues (CSS).
  2932     * SystemAdmin macro now checks against cfg.superuser list.
  2933 
  2934   Other changes:
  2935     * Added turkish i18n. To be considered as alpha as it got in last minute.
  2936 
  2937 
  2938 Version 1.5.0rc1:
  2939   This is the first release candidate of MoinMoin 1.5.0.
  2940   
  2941   Fixes:
  2942     * fixed broken logs when a DeletePage (maybe also RenamePage) comment
  2943       contained CR/LF characters (could happen when using copy&paste)
  2944     * fixed GUI editor MoinEditorBackup page containing HTML instead of wiki
  2945       markup
  2946     * fixed invalid HTML in FootNotes
  2947     * fixed HTML source in EditorBackup after canceling GUI editor
  2948     * Footnotes of included pages are not shown at the bottom of the including page.
  2949     * Bug in Dict handling that often breaks first entry
  2950 
  2951 Version 1.5.0beta6:
  2952   Authentication:
  2953     * Added SSO module for PHP based apps. Currently supported: eGroupware 1.2.
  2954       No need to login in two systems anymore - MoinMoin will read the PHP session
  2955       files.
  2956 
  2957   Fixes:
  2958     * Improved rendering of bullet lists and external links in Restructured text.
  2959       Thanks to Matthew Gilbert.
  2960     * Fixed modern theme rendering, including some fixes and workarounds for
  2961       broken MS IE.
  2962     * When checking for email uniqueness, do not compare with disabled user
  2963       profiles.
  2964     * Fix sending of HTTP headers for Despam action.
  2965     * Add some margin left and right of the link icons.
  2966 
  2967   Other changes:
  2968     * Made it easier for auth methods needing a user interface (like ldap or
  2969       mysql stuff). Unlike http auth, they usually need some "login form".
  2970       We made UserPreferences login form values (name, password, login, logout)
  2971       available as kw args of the auth method, so it is easy and obvious now.
  2972     * Make login and logout show at the same place. Is only shown when
  2973       show_login is True (default).
  2974     * Disabled login using &uid=12345.67.8910 method. Please use name/password.
  2975     * Made builtin moin_cookie authentication more modular: the cookie is now
  2976       touched by MoinMoin.auth.moin_cookie only, with one minor discomfort:
  2977       When creating a user, you are not automatically logged in any more.
  2978     * We now use the packager for additional help and system pages in all other
  2979       languages except English. The packages are attached to SystemPagesSetup
  2980       page and can be installed from there after getting "superuser" powers.
  2981       The "extra" package contains a collection of orphan pages not listed on
  2982       some SystemPagesIn<Language>Group page.
  2983 
  2984 
  2985 Version 1.5.0beta5:
  2986   Fixes:
  2987     * Fixed a minor user interface bug: it showed RenamePage and DeletePage
  2988       actions in the menu if you only had write rights and then complained
  2989       when you really tried when you had no delete rights additionally.
  2990     * We don't remove RenamePage and DeletePage from menu any more if user is
  2991       unknown. This stuff is only driven by ACLs now.
  2992     * Some fixes to Despam action.
  2993     * Fixed moin_dump (broken by some recent theme init change).
  2994     * Fixed a few tests by moving the theme init from moin_dump to RequestCLI.
  2995     * removed old_onload reference from infobox.js
  2996     * Fixed MoinMoin logo for IE.
  2997     * search: fixed whitespace handling in linkto: search terms
  2998     * Increased stability of the tests system by outputting results to sys.stdout
  2999       instead of request. Note that this changes the semantics for e.g. mod_py or
  3000       mod_fcgi.
  3001     * Fixed packaging system in the case of AddRevision that does not alter the page.
  3002     * Fixed a few bugs in the XML formatters (dom_xml, text_xml, xml_docbook).
  3003     * Fixed link icons. We now just use a.xxx.before where xxx is the link scheme,
  3004       e.g. a.http.before. See theme's common.css.
  3005     * Hopefully fixed some issue with non-ASCII attachment filenames.
  3006     * Workaround for Opera 8.5 making silly "No addition" categories.
  3007     * Do not show GUI editor for non-wiki format pages, because we only have a
  3008       converter from html to wiki right now.
  3009     * Fix the modern CSS issues for editbar, when it shifted content far right.
  3010       Also removed the absolute height value that never was right.
  3011     * Fix mod_python adaptor bugs failing to handle Location correctly.
  3012       See: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=339543
  3013 
  3014   Other changes:
  3015     * Added irc:// to the builtin supported link schemas. You can remove it
  3016       from config.url_schemas in case you have patched it in there.
  3017     * Added cfg.user_autocreate (default: False). Use True to enable user
  3018       profile autocreation, e.g. when you use http authentication, so your
  3019       externally authenticated users don't need to create their moin profile
  3020       manually. The auth method (see cfg.auth list) must check this setting
  3021       if it supports auto creation.
  3022     * Added user_autocreate support for auth.http and auth.sslclientcert.
  3023     * Added "." and "@" to allowed characters in usernames. This is needed
  3024       e.g. when using mod_pubcookie for authentication. mod_pubcookie returns
  3025       userids like "geek@ANDREW.CMU.EDU" (e.g. the Kerberos domain is part of
  3026       the id). Thanks to Brian E. Gallew for his patch, which we used for
  3027       inspiration for user autocreation changes.
  3028     * Changed auth method to return a tuple (user_obj, continue_flag), see
  3029       comments in auth.py.
  3030     * auth methods now create user objects with kw args auth_method and
  3031       auth_attribs, so that moin knows later how the user was authenticated
  3032       and which user object attributes were determined by the auth method.
  3033     * Added MoinMoin/scripts/import/IrcLogImporter.py to import supybot's
  3034       IRC logs into a moin wiki. We use MonthCalendar compatible page names,
  3035       so you can use the calendar for showing / navigating the logs.
  3036     * Removed packager binary from FCKeditor (fixing a Debian policy problem).
  3037     * Worked around .png transparency bugs of IE with the new logo. We ship
  3038       two logos: moinmoin.png without an alpha channel (IE compatible) and
  3039       moinmoin_alpha.png which has an alpha channel and looks better on
  3040       browsers with full .png support.
  3041     * Allow a .zip file to have a directory in it if it is the only one.
  3042 
  3043 Version 1.5.0beta4:
  3044   Fixes:
  3045     * use <span class="anchor"> instead of <a> for line-xxx anchors, this
  3046       fixes some rendering problems on IE
  3047     * Fixed the ReStructured text parser when it was used with non-HTML
  3048       formatters. Increased compatiblity with new docutils code.
  3049       (Thanks to Matt Gilbert.)
  3050   Other changes:
  3051     * cfg.stylesheets = [] (default). You can use this on wiki or farm level
  3052       to emit stylesheets after the theme css and before the user prefs css.
  3053       The list entries must be ('screen', '/where/ever/is/my.css') style.
  3054     * Added sample code for auth using an external cookie made by some other
  3055       program. See contrib/auth_externalcookie/*. You need to edit it to
  3056       fit whatever cookie you want to use.
  3057 
  3058 Version 1.5.0beta3:
  3059   Fixes:
  3060     * fixed editor preview throwing away page content for new pages
  3061     * require POST for userform save and create* action
  3062     * use request.normalizePagename() while collecting pagelinks
  3063     * do not offer gui editor for safari
  3064   Other changes:
  3065     * tell user if account is disabled
  3066     * added support for linking to .ico and .bmp
  3067     * attachment methods for the text_xml and xml_docbook formatters
  3068     * new favicon
  3069     * updated i18n (fixed nl, did nobody notice this?) and underlay
  3070     * changed show_interwiki default to 0
  3071 
  3072 Version 1.5.0beta2:
  3073   Fixes:
  3074     * fix wrong _ in title links (MoinMoinBugs/AddSpaceWikiNameAtHead)
  3075     * fix gui editor (converter) crash on save
  3076     * MoinMoinBugs/PageHitsFails
  3077     * MoinMoinBugs/PackagePagesFailsBecauseAllowedActionsMissing
  3078     * Avoid destroying existing page content if editor is called with
  3079       template parameter for an existing page.
  3080     * fix countdown javascript for browser status line in editor
  3081     * added page title display for editor
  3082     * added header div for classic theme
  3083 
  3084   Authentication and related:
  3085     * Added a WhoAmI.py wiki xmlrpc plugin to check whether auth works
  3086       correctly for xmlrpc. There is a counterpart script WhoAmI.py that
  3087       uses http auth when calling the xmlrpc plugin, so you can use it to
  3088       check http auth.
  3089 
  3090 Version 1.5.0beta1:
  3091     * Requirements changed to require Python >= 2.3. We recommend that
  3092       you use the latest Python release you can get. The reason we
  3093       dropped 2.2.2 support is because no developer or tester uses this
  3094       old version any more, so incompatibilities crept in the code
  3095       without anybody noticing. Using some recent Python usually is no
  3096       real problem, see there for some hints in case you still run an
  3097       old python: http://moinmoin.wikiwikiweb.de/NewPythonOnOldLinux
  3098       The hint also does apply to other POSIX style operating systems,
  3099       not only Linux.
  3100     * We recommend you use MoinMoin/scripts/cachecleaner.py to clean the
  3101       wiki's cache (see comments at top of the script).
  3102       The cache will automatically be rebuilt (some operations may take
  3103       some time when first being used, e.g. linkto: search, so be patient!).
  3104 
  3105   Config Changes:
  3106      * there is a file CHANGES.config with just the recently changed stuff
  3107        from multiconfig.py
  3108      * new defaults:
  3109        * page_front_page old: u"FrontPage" new: u"HelpOnLanguages"
  3110          please just read the help page in case you see it :)
  3111        * bang_meta old: 0 new: 1
  3112        * show_section_numbers old: 1 new: 0
  3113        * some regexes that used to be [a-z]Uxxxx$ are now [a-z0-9]Uxxxx$
  3114        * navi_bar has no page_front_page as first element any more
  3115      * removed settings and code [new behaviour]:
  3116        * acl_enabled [1]
  3117        * allow_extended_names [1]
  3118        * allow_numeric_entities [1]
  3119        * backtick_meta [1]
  3120        * allow_subpages [1]
  3121      * new settings:
  3122       * cfg.mail_sendmail = "/usr/sbin/sendmail -t -i" can be used if sending
  3123         via SMTP doesn't work on your server. Default is None and that means
  3124         using SMTP.
  3125       * language_default replaces the old default_lang setting (just renamed).
  3126       * language_ignore_browser = True can be used to let moin ignore the
  3127         user's browser settings (e.g. if you run a local-language only wiki
  3128         and your users use misconfigured or buggy browsers often). Default is
  3129         False. Don't forget to set language_default when using this.
  3130  
  3131     * Wiki Editor changes / new WYSIWYG editor
  3132      * fully imported the javascript based LGPLed FCKeditor (many thanks
  3133       to Fred CK for his great work). See http://fckeditor.net/ for details.
  3134      * config for FCKeditor is at wiki/htdocs/applets/moinfckeditor.js
  3135      * added cfg.interwiki_preferred (default = []) to set a list of wikis to
  3136        show at the top of the wiki selection list when inserting an
  3137        interwiki link (just use the same wiki name as in interwiki
  3138        map). If the last list item is None, then the preferred wikis
  3139        will not be followed by the entries of the interwiki map.
  3140     * moved save/preview/... buttons to the top so that they can be
  3141       easily reached
  3142     * reduced edit_rows default to 20 lines
  3143     * Added support for edit by doubleclick in the diff view
  3144 
  3145     * Improved wiki farm support
  3146      * make user files sharable between several wikis in a farm
  3147       * allow/use interwiki subscriptions
  3148       * use interwiki links in page trail
  3149       * save bookmark per wiki name
  3150      * cfg.cookie_domain can be used to set a cookie valid for a complete
  3151        domain (default: None == only for this host). If you use '.domain.tld',
  3152        the cookie will be valid for all hosts *.domain.tld - good for host
  3153        based wiki farms.
  3154      * cfg.cookie_path can be used to set a cookie valid for a wiki farm under
  3155        some base path (default: None == only for this wiki's path). If you use
  3156        '/wikifarm',  the cookie will be valid for all wikis
  3157        server.tld/wikifarm/* - good for path based wiki farms.
  3158      * Interwiki user homepage (if you have MANY users)
  3159        Generated links for usernames are interwiki now, use cfg.user_homewiki
  3160        (default: 'Self') to specify in which wiki the user home pages are
  3161        located. Note: when pointing this to another wiki, the /MoinEditorBackup
  3162        functionality will be disabled.
  3163        @SIG@ also uses interwiki when needed.
  3164 
  3165     * Authentication, ACLs and related
  3166      * Modular authentication: cfg.auth is a list of functions that return a
  3167        valid user or None, use it like this:
  3168            from MoinMoin.auth import http, moin_cookie
  3169            auth = [http, moin_cookie]
  3170      * cfg.auth_http_enabled was removed, please use cfg.auth instead.
  3171      * http auth now supports "Negotiate" scheme, too
  3172      * Added sslclientcert auth method (Apache: untested, Twisted: not
  3173        implemented, IIS: no idea). See MoinMoin/auth.py for details.
  3174        Submit a patch if you have improvements.
  3175      * cfg.superuser is a list of unicode usernames. It is used by some
  3176        critical operations like despam action or PackageInstaller.
  3177      * removed allowed_actions, we now use actions_excluded only and it
  3178        defaults to [], that means, no action is excluded, everything is
  3179        allowed (limited by ACLs). In case of RenamePage and DeletePage,
  3180        this shouldn't be a problem as both can be reverted. In case you
  3181        did not allow attachments, you now have to use:
  3182        actions_excluded = ['AttachFile']
  3183      * special users (All, Known, Trusted) in Groups are now supported
  3184      * MoinMoin.security.autoadmin SecurityPolicy added
  3185        When using this security policy, a user will get admin rights on his
  3186        homepage (where pagename == username) and its sub pages. This is needed
  3187        for the MyPages action, but can also get used for manual ACL changes.
  3188        It can also be used for Project page auto admin functionality, see the
  3189        comments in the script for details.
  3190        Further it can automatically create the user's group pages when the
  3191        user saves his homepage.
  3192      * there is a UpdateGroup xmlrpc call, see MoinMoin/xmlrpc/UpdateGroup.py -
  3193        you can use this to update your *Group pages e.g. when generating them
  3194        from an external group database.
  3195 
  3196     * UserPreferences changes
  3197      * Alias name: is used for display purposes, when "name" is cryptic. It is
  3198        shown e.g. in the title attribute of userid links (displayed when
  3199        moving the mouse over it).
  3200      * "Publish my email (not my wiki homepage) in author info" - use this
  3201        if you don't have a wiki homepage, but if you want to be contactable
  3202        by email. When you edit a page, your email address will be published
  3203        as mailto: link on RecentChanges, at bottom of page (last editor) and
  3204        in page info. If the wiki runs publically on the internet, be careful
  3205        using this or your email address might be collected by spammers.
  3206      * Preferred Editor: whether you want to use the text editor (as in
  3207        previous moin versions), the gui editor (new!) or both (you will get
  3208        2 edit links in that case).
  3209      * a user can add/remove the current page to/from his quicklinks with an
  3210        appropriate action now
  3211      * if cfg.user_email_unique = False, we don't require user's email
  3212        addresses to be unique
  3213      * removed show_fancy_links user preferences setting to simplify code and
  3214        caching. Displaying those icons is now done by CSS styles (see
  3215        common.css). Maybe needs fixing for non-standard themes and RTL langs.
  3216 
  3217     * Markup
  3218      * added strikethrough markup: --(striked through text here)--
  3219      * @ME@ expands to just the plain username (no markup added) on save
  3220     
  3221     * User homepages
  3222      * when a user accesses his own non-existing homepage (pagename ==
  3223        username), the wiki will present the MissingHomePage system page
  3224        content, explaining what a user homepage is good for and offer
  3225        one-click editing it with content loaded from HomepageTemplate
  3226      * creation of homepage subpages is assisted by the MyPages action, which
  3227        offers rw, ro page creation (and a related group) or creation of private
  3228        pages. If you are not in the user_homewiki, you will get redirected
  3229        there first.
  3230 
  3231   Other changes/new features:
  3232     * Added PackageInstaller and unzipping support (see wiki page
  3233       HelpOnActions/AttachFile for further details).  PackageInstaller requires
  3234       the user to be in cfg.superuser list.
  3235      * Added an PackagePages action to simplify the package creation.
  3236     * Added location breadcrumbs - when you are on some subpage, the page
  3237       title parts link to the corresponding parent pages, the last part does
  3238       the usual reverse linking.
  3239     * added WSGI server support, thanks to Anakim Border, see:
  3240       wiki/server/moinwsgi.py (moin as WSGI app, uses the flup WSGI server,
  3241                                see http://www.saddi.com/software/flup/)
  3242       MoinMoin/server/wsgi.py (adaptor code)
  3243     * added a "Despam" action to make de-spamming a wiki easy (mass revert
  3244       bad changes done by a single author or bot). You need to be in
  3245       cfg.superuser to use it.
  3246     * Better diffs with links to anchors to the changed places
  3247     * Enhanced table support in the DocBook formatter.
  3248     * Added 'moin' daemon script, that let you run moin standalone
  3249       server as daemon and control the server with simple command line
  3250       intreface: moin start | stop | restart | kill
  3251     * Add 'restart' option to mointwisted script
  3252     * Add properties option to standalone server config. Allow
  3253       overriding any request property like in other server types.
  3254     * Add support for running behind proxy out of the box with out
  3255       manual url mapping.
  3256       See HelpOnConfiguration/IntegratingWithApache
  3257     * added a WikiBackup action, configure it similar to this:
  3258       data_dir = "/path/to/data"
  3259       backup_include = [data_dir, ] # you can add other dirs here
  3260       backup_users = ["BackupUserName", ] # only TRUSTED users!
  3261       You usually don't need to change the default backup_exclude setting.
  3262       The default backup_include list is EMPTY and so will be your
  3263       backup in case you don't configure it correctly.
  3264       If you put your data_dir there, the backup will contain private
  3265       user data like email addresses and encrypted passwords.
  3266     * Added a SubscribeUser action which allows the administrator to subscribe users to the
  3267       current page.
  3268     * Added thread count to SystemInfo macro.
  3269     * Added Petr's newest patch against the DocBook code. It allows you to use macros (esp. the include macro) in DocBook pages in order to build larger documents.
  3270     * Added a RenderAsDocbook action which redirects to the DocBook formatter.
  3271     * Added searching for wiki-local words lists under <data_dir>/dict/.
  3272       They are used additionally to the global lists in MoinMoin/dict/.
  3273     * moin_dump now also dumps attachments referenced from the page.
  3274       It doesn't dump stuff that is just attached, but not referenced!
  3275     * On RecentChanges we now force the comment to be breakable, this improves
  3276       rendering of over-long words or on narrow browser windows - especially
  3277       for themes with limited content width like rightsidebar.
  3278     * We now have the "new" icon on RecentChanges clickable, just links to the
  3279       page.
  3280     * Print view now shows "interwikiname: pagename" (for show_interwiki = 1).
  3281 
  3282   International support:    
  3283     * mail_from can be now a unicode name-address 
  3284       e.g u'Jürgen wiki <noreply@jhwiki.org>'
  3285 
  3286   Theme changes:
  3287     * logo_string is now should be really only the logo (img).
  3288       If you included your wiki's name in logo_string you maybe want to remove
  3289       it now as it is shown as part of the location display now anyway (if
  3290       you set show_interwiki = 1).
  3291     * You maybe want to remove page_front_page from your navi_bar - we link to
  3292       that page now from the logo and (new, if you set show_interwiki = 1) from
  3293       the interwiki name displayed in location display, so you maybe don't need
  3294       it in navi_bar, too.
  3295     * If you have a custom theme, you should / may:
  3296      * sync modern/css/screen.css #pagelocation #pagetrail stuff to your
  3297        screen.css or pagelocation display (title()) will look strange (like a
  3298        list).
  3299      * remove "#title h1 ..." CSS (or any other CSS assuming h1 is a page
  3300        title and not just a first level heading), it is not used any more.
  3301      * we now render = heading = as <h1> (was <h2> before 1.5),
  3302        == heading == as <h2> (was <h3>), etc.
  3303      * maybe move both title() and trail() to header area, like the builtin
  3304        themes do it.
  3305      * there is a new interwiki() base theme method that optionally (if
  3306        show_interwiki = 1) shows the interwiki name of this wiki and links to
  3307        page_front_page. The css for it is #interwiki.
  3308 
  3309   Developer notes:    
  3310     * Plugin API was improved. When plugin module is missing,
  3311       wikiutil.PluginMissingError is raised. When trying to import a
  3312       missing name from a plugin module, wikiutil.PluginMissingError is
  3313       raised. You must update any code that use wikiutil.importPlugin.
  3314       Errors in your plugin should raise now correct tracebacks. See
  3315       http://moinmoin.wikiwikiweb.de/ErrorHandlingInPlugins
  3316     * pysupport.importName was changed, it does not check for any
  3317       errors when trying to import a name from a module. The calling
  3318       code should check for ImportError or AttributeError. Previous
  3319       code used to hide all errors behind None.
  3320     * Its easier now to customize the editbar by overriding
  3321       editbarItems() in your theme, and returning a list of items to
  3322       display in the editbar. To change a single editbar link, override
  3323       one of the xxxLink methods in your theme.
  3324 
  3325   Internal Changes:
  3326     * request.formatter (html) is available for actions now
  3327     * theme API's d['page_home_page'] is gone (sorry) and replaced by
  3328       d['home_page'] which is either None or tuple (wikiname,pagename).
  3329       It is better to use the base classes function for username/prefs anyway.
  3330     * introduced cfg.hacks for internal use by development, see comment in
  3331       multiconfig.py and file HACKS.
  3332     * added IE7 (v0.9) from Dean Edwards (see http://dean.edwards.name/IE7/) -
  3333       that should fix quite some IE bugs and annoyances (on Win32).
  3334       * for enabling IE7, use cfg.hacks = { 'ie7': True }
  3335     * reducewiki now also copies all attachments (we use that to make underlay
  3336       directory from moinmaster wiki's data_dir)
  3337 
  3338   Fixes:  
  3339     * Fixed a typo in xslt.py which led to a traceback instead of an
  3340       error message in case of disabled XSLT support.
  3341     * Fixed crash in twisted server if twisted.internet.ssl is not
  3342       available.
  3343     * Fixed wrong decoding of query string, enable wiki/?page_name urls
  3344       with non ascii page names.
  3345     * Fixed wrong display of non ascii attachments names in
  3346       RecentChanges and page revision history.
  3347     * Fixed a crash when trying to run standalone server on non posix os.
  3348     * Fixed highlight of misspelled words in Check Spelling action.
  3349     * Fixed case insensitivity problems on darwin (Mac OS X). See
  3350       MoinMoinBugs/MacHfsPlusCaseInsensitive
  3351     * Added RecentChanges (only the english one) to the pages getting
  3352       html_head_index headers
  3353     * text_html cache files written with this code will invalidate themselves
  3354       if they detect to be older than the wikiconfig. Note: you should remove
  3355       all old text_html cache files once after upgrading, they will then be
  3356       rebuilt automatically with the new code.
  3357     * Fixed MoinMoinBugs/12_to_13_mig10_Walk
  3358     * Fixed the word_rule: a word like AAAbbAbb isn't teared into two parts
  3359       any more (was: AA<link>AbbAbb</link>)
  3360     * Fixed false positive InterWiki markup for languages like Finnish.
  3361       InterWiki links are only rendered if the left side has an appropriate
  3362       entry in the interwiki map, otherwise it is rendered as simple text.
  3363     * Fixed unicode error when uploding non-ascii file name using mod
  3364       python.
  3365     * Fixed error handling of wikirpc requests, should give more
  3366       correct errors and prevent no error output and blocking the
  3367       client in some cases.
  3368     * Fixed the "lost password" mail processing. If a user entered some email
  3369       address unknown to the system, he was not notified of this, but just got
  3370       a useless mail with no account data in it. Now the system directly tells
  3371       the user that he entered an unknown email address.
  3372     * Fixed SystemInfo, it now also lists parsers in data/plugin/parser dir.
  3373     * Fix error handling on failure, improved error display
  3374     * Fix error handling when importing plugins or importing modules
  3375       dynamically. The fix is not backward compatible with older plugins.
  3376     * Fix chart action, returns a page with error message when chart
  3377       can not be created.
  3378     * Fixed formatter usage in the ShowSmileys macro.
  3379     * Fixed updating pagelinks cache for [:page:text] or [wiki:Self:page text],
  3380       fixes display of LocalSiteMap and rendering of such links.
  3381     * Hopefully fixed urllib problems (esp. with py 2.4.2, but also before) by
  3382       using our own urllib wrapper that handles encoding/decoding to/from
  3383       unicode, see wikiutil.py. Also made a similar fix for making and parsing
  3384       query strings.
  3385     * Fixed MonthCalendar tooltips when containing special chars like quotes.
  3386     * Added html escaping for diff text for RSS feed with diff=1.
  3387     * The distance between page content beginning and the first = heading =
  3388       was much too much. Fixed.
  3389     
  3390 Version 1.4:
  3391 
  3392     We used that version number for an internal and early development version
  3393     for what will be called moin 2.0 at some time in the future.
  3394     There will never be a 1.4.x release.
  3395 
  3396 
  3397 Version 1.3.5 (2005-08-04, Revision moin--main--1.3--patch-883)
  3398 
  3399 Fixes:
  3400     * small CSS fix for rightsidebar theme
  3401     * applied some Debian patches (thanks to Jonas!):
  3402       * de i18n spelling fixes
  3403       * AttachFile fix, we strip CR in .draw files now
  3404       * when loading spellcheck dictionaries, we want utf-8, but we make
  3405         a 2nd try with iso-8859-1 encoding.
  3406 
  3407 New Features:
  3408 
  3409     * enabled using https with the Twisted server:
  3410       You need to use port 443, have PyOpenSSL (+ ssl libs it depends on)
  3411       installed and have some site key and certificate PEM files configured in
  3412       your twistedmoin.py file:
  3413       sslcert = ('/whereever/cert/sitekey.pem', '/whereever/cert/sitecert.pem')
  3414 
  3415 
  3416 Version 1.3.5rc1 (2005-07-31, Revision moin--main--1.3--patch-865)
  3417 
  3418 Fixes:
  3419 
  3420     * Fixed security bug when acl of deleted page was ignored. See:
  3421       http://moinmoin.wikiwikiweb.de/MoinMoinBugs/ACLIgnoredAfterDelete
  3422     * AttachFile did not display the original filename plus there
  3423       was a confusion in input field labelling ('Rename to').
  3424     * Fixed shortcut link non-existent page detection.
  3425     * Fixed non-working bookmark function on python 2.2.x.
  3426     * Fixed wikirpc getPageInfo call on python 2.2.x.
  3427     * Fixed the failing import of plugins from the data/plugin/
  3428       directories if run in zipimport environments.
  3429     * Fixed traceback which occurred on negated searches.
  3430     * Fixed crash when trying to render error message on twisted, fast
  3431       cgi and modpy.
  3432     * Fixed error message with modpy, used to show wrong errors below
  3433       the real message.
  3434     * Fixed search and goto text fields for better compatibility with
  3435       dark themes and better control through css.
  3436     * Show an edit link if MissingPage is missing and a warning in the
  3437       server log.
  3438     * Fixed missing footer in the editor.
  3439     * Fixed indented (invalid) headings with broken links in table of
  3440       contents.
  3441     * Fixed crash when file name is too long, show standard error message.
  3442     * Save trail file in a safe way, should be enough for normal use.
  3443     * Fixed remember_last_visit user preferences option when show_trail
  3444       is not selected.
  3445     * Fixed the tests for Standalone, Twisted, FastCGI and Mod_Python.
  3446       Run with ?action=test from any page.
  3447     * Fixed rare bug when wrong search type was performed when pasting
  3448       search term in Safari.
  3449     * Fixed crash for custom formatters and dom_xml (which occurred if
  3450       smileys were in the page).
  3451     * Editor opens on double click in pages with single quote in the
  3452       name, like "Ben's Wiki".
  3453     * '/.' in page names are not replaced any more by '/(2e)'
  3454     * Fixed the long delays while saving pages using RequestCLI.
  3455     * Fixed variable expanding for users with non WikiName.
  3456     * Fixed MonthCalendar's calculation of "today" to use the user's
  3457       time zone setting.
  3458     * Fixed moin_dump script, use same configuration options as other
  3459       scripts.
  3460     * Fixed url_mappings to work in proxied setups and sent mails
  3461       again. Also fixed for image links. Thanks to JohannesBerg.
  3462     * Fixed page shown after saving a drawing (esp. when saved from a
  3463       sub page). Fixed help link for drawings.
  3464     * Fixed mig10 script to run on Python < 2.3.
  3465     * The twisted server defaulted to a socket timeout of 12 hours!
  3466       We reduced that to a more sane 10 minutes, that should still be more
  3467       than enough. This fixed the "too many open files" problem we
  3468       encountered quite often recently. Thanks to Helmut Grohne!
  3469 
  3470 Other Changes:
  3471 
  3472     * Added {hu} flag.
  3473     * Added cz, pt and pt-br i18n.
  3474     * We send a 404 http status code for nonexisting wiki pages now,
  3475       maybe this will repell some search engines from requesting gone
  3476       pages again and again. The wiki user still sees the MissingPage
  3477       wiki stuff, so a user usually won't notice this change.
  3478     * Return 500 error code on failure and exceptions.
  3479     * Added some more bot / leech tool user agent strings.
  3480     * Prevent page floating elements from floating out of the page over
  3481       the footer, in modern, rightsidebar and classic themes.
  3482     * Encode URLs in a safer way
  3483     * We allow usernames with ' character in them now (like Tim O'Brian).
  3484     * Added support for the new security flags in docutils 0.3.9.
  3485     * @MAILTO@ expands now to safer [[MailTo()]] macro.
  3486     * Clarified and i18ned lost password mails.
  3487     * Added 'TitleIndex' and 'SiteNavigation' (+ translation) to the
  3488       list of pages that use html_head_index (so that robots
  3489       "index,follow").  Please make sure to have either FindPage,
  3490       TitleIndex or SiteNavigation in your navi_bar or in your
  3491       page_front_page content if you want search engines to find all
  3492       your pages.
  3493     * Make it possible to send account data when being logged in (for
  3494       future reference or whatever purpose).
  3495     * Speed up when running with persistent servers, the wiki config
  3496       does only get loaded once and misc. stuff is being cached between
  3497       requests now.
  3498     * The unit tests are disabled when using multi threading, because
  3499       the wiki configuration is shared between diffrent threads.
  3500     * The main code path (using standalone server) of MoinMoin runs on
  3501       PyPy now.
  3502     * Formatters do automatically transform HTML to plain text if they are
  3503       called with raw HTML code.
  3504     * Using larger socket backlog on Standalone and FastCGI servers
  3505       should be more reliable on high load.
  3506     * We now strip leading path from attachments uploaded by IE (this is
  3507       a bug in IE, not in MoinMoin). Better use a sane browser, like Firefox.
  3508     * added "teleport" to the user agent blacklist
  3509 
  3510 New Features:
  3511 
  3512     * Integrated Lupy indexer for better search performance. It is disabled
  3513       by default as of 1.3.5 as it still has known issues.
  3514       See multiconfig.py if you want to test it.
  3515     * Integrated MonthCalendar 2.1, with some new features:
  3516       * a mouseover bubble that shows first level headlines of the linked
  3517         day page
  3518       * all calendars with same pagename move when using cal navigation,
  3519         thanks to Oliver Graf
  3520       * included AnnualMonthlyCalendar patch of Jonathan Dietrich
  3521         (use [[MonthCalendar(Yearly,,,+1,,6,1)]] syntax for birthdays and
  3522         other annually repeating stuff)
  3523       Make sure you remove old MonthCalendar.* from data/plugin/macro so that
  3524       moin will use the new code in MoinMoin/macro/MonthCalendar.py.
  3525       Maybe also clear the text_html cache.
  3526     * Added the new XSLT parser and the DocBook parser. This should increase
  3527       the 4suite compatiblity. See HelpOnXmlPages for details.
  3528       It now should run on 4suite 1.0a4 and 1.0b1. Thanks to Henry Ho!
  3529     * Added the DocBook formatter. This will let you generate DocBook markup
  3530       by writing simple wiki pages. It needs PyXML.
  3531     * It is now possible to customize parts of the UserPreferences page in
  3532       your wikiconfig (changing defaults, disabling fields, removing fields):
  3533       * Use user_checkbox_* for the checkboxes.
  3534       * Use user_form_* for other fields.
  3535       * See MoinMoin/multiconfig.py for the built-in defaults.
  3536     * New standalone server classes: ThreadPoolServer using pool of
  3537       threads, ThreadingServer with thread limit and ForkingServer.
  3538     * New standalone server configuration options: serverClass,
  3539       threadLimit, requestQueueSize.
  3540     * Use "PythonOption Location" in mod_python setup to solve script_name
  3541       problems.
  3542 
  3543 Developer notes:
  3544     
  3545     * Theme can now override maxPagenameLength() method to control page
  3546       name shortening.
  3547     * A search Match now provides access to the full re match via
  3548       the re_match attribute (use to access groups of the match)
  3549     * Underlay is not managed by arch any more. The tree contains an
  3550       underlay tarball, and you should untar after you update from main.
  3551     * "make update-underlay" will untar underlay
  3552     * "make merge" will star-merge main into your tree
  3553     * "make test" will now create and run in a fresh testwiki instace
  3554     * "make clean" options added
  3555     * _tests module does not have a global request any more. To refer to
  3556       the current request in a test, use self.request.
  3557     * _tests.TestConfig class require a request in the constructor.
  3558     * "python tests/runtests.py test_module" will run only test_module
  3559     * request.cfg stays between requests (for persistent servers).
  3560 
  3561 
  3562 Version 1.3.4 (2005-03-13, Revision moin--main--1.3--patch-666)
  3563 
  3564 Fixes:
  3565 
  3566     * Fixed ACL check in LikePages macro that caused links to unreadable 
  3567       pages to show.
  3568     * Fixed ACL check in newpage action.
  3569     * Fixed a security problem when admin policy defined in a custom
  3570       SecurityPolicy class was ignored.
  3571     * Fixed ACL check in action=show so that a user who may not read a page
  3572       also can't find out WHEN the protected page was updated.
  3573     * Workaround on Windows 95, 98, ME in order to clear the dircache.
  3574       This fixes some bugs related to an outdated page list and newly created
  3575       pages that did not appear immediately.
  3576     * Fixed decoding issues of page names on Windows, finally.
  3577       http://moinmoin.wikiwikiweb.de/MoinMoinBugs/BrokenUmlautsInLinksIn131
  3578     * Fixed traceback on IIS.
  3579       http://moinmoin.wikiwikiweb.de/MoinMoinBugs/request%2epy_broken_on_IIS
  3580     * Fixed wikirpc for standalone server.
  3581     * Other fixes (encoding and str/unicode data type related) to wikirpc
  3582       server, fixing some non-ascii issues hopefully.
  3583     * Fixed broken query strings for Standalone installations.
  3584     * Fixed backlinks - the result did not always show all links, often it 
  3585       showed too many irrelevant matches (MoinMoinBugs/BacklinksAreBroken).
  3586     * Fixed the acceptance of the show_hosts setting. Now you should be able
  3587       to hide any IP or host name from being published by MoinMoin by enabling
  3588       this option.
  3589     * Fixed wrong line endings on email messages.
  3590     * Fixed MoinMoinBugs/StandaloneUnquotesTooMuch.
  3591     * Fixed crash when trail file is missing.
  3592     * Fixed a traceback when searching for single ( or ).
  3593     * Added mig10 script to fix crashes with uncoverted edit-locks and file
  3594       attachments. Just use it as you did with mig1..mig9 before.
  3595     * Added mig11 script to add __init__.py files to data/plugin (and below).
  3596     * added some fixes for the xslt parser (thanks to fanbanlo), it might be
  3597       still broken, but someone with deeper knowledge about xslt should fix it.
  3598     * Replaced image link with W3C's "html 4.01 compliance" icon by a simple
  3599       text link to avoid https: or config trouble.
  3600     * Catch OverflowError backtrace when illegal date strings (e.g. <1970 or
  3601       >2038) are fed to moinmoin's time routines. It will just output current
  3602       date / time in those cases.
  3603     * UserPreferences now also set a date_fmt preference and Date macro
  3604       honours it. You may have to reset your UserPreferences value for that.
  3605     * Fixed free parent and subpage links in interwiki notation.
  3606       http://moinmoin.wikiwikiweb.de/MoinMoinBugs/FreeParentLinksAreBroken
  3607     * Fixed a traceback for invalid ReST markup.
  3608     * Fixed UnicodeError in SystemAdmin's Attachment Browser.
  3609 
  3610 Other Changes:
  3611 
  3612     * Optimized the IRC parser.
  3613     * Support for zipimport of the MoinMoin package. This allows you to use
  3614       py2exe and similar programs.
  3615     * Show the editor's name in the mail subject.
  3616     * Added the pragmas description and keywords. They will add <meta> headers
  3617       if used.
  3618     * Added MoinMoin/scripts/xmlrpc-tools/putPageTest.py example script, useful
  3619       as a starting point for importing data using wiki xmlrpc.
  3620     * Optimised display on Opera browser.
  3621 
  3622 New features:
  3623 
  3624     * The search modifier "linkto:" was introduced. You can use it to search
  3625       for links.
  3626     * The NewPage macro now can take a PageTemplate parameter, see HelpOnMacros.
  3627     * New config settings (so you don't need to edit wikirpc.py any more):
  3628       xmlrpc_putpage_enabled = 0 (if 1, enables writing to arbitrary page names)
  3629       xmlrpc_putpage_trusted_only = 1 (if 0, doesn't require users to be
  3630        authenticated by http auth - DANGEROUS, DO NOT SET TO 0!!!)
  3631     * Added support for Digest and NTLM authentication with CGI (e.g. if you
  3632       use those Apache modules)
  3633     * The datetime string accepted by Date and DateTime macros was extended to
  3634       accept a timezone specification, so now +/-HHMM is also valid, e.g.:
  3635       2005-03-06T15:15:57Z (UTC, same as +0000)
  3636       2005-03-06T15:15:57+0000 (UTC)
  3637       2005-03-06T16:15:57+0100 (same time given as local time for time zone
  3638                                 with offset +0100, that is CET, e.g. Germany)
  3639       2005-03-06T10:15:57-0500 (same time given as local time for time zone
  3640                                 with offset -0500, EST, US Eastern Std. Time)
  3641       The values given as macro argument will be transformed to UTC internally
  3642       and then adapted again according to viewing user's UserPreferences, so
  3643       the user will see the same moment in time but shown in his local time
  3644       zone's time (at least if he set his UserPreferences correctly and didn't
  3645       forget changing them twice a year for DST and non-DST).
  3646     * Readded (now optional) editlink footer to Include macro. Add
  3647       ',editlink' to call to enable this.
  3648     * star "smileys" e.g. {*}{*}{*}{o}{o}

  3651 Version 1.3.3 (2005-01-24, Revision moin--main--1.3--patch-595)
  3652 
  3653 Fixes:
  3654 
  3655     * fixed ACL security problem in search
  3656     * fix for IIS with CGI allowing page names that contain chars
  3657       that are not in the system code page
  3658     * fixed MoinEditorBackup revisions to start with 1 now
  3659     * improved page locking ('current' file)
  3660     * Unittests (normally shown at end of action=test output) are currently
  3661       disabled for everything except CGI, because they only work reliably with
  3662       CGI, giving wrong results for other request methods.
  3663 
  3664 
  3665 Version 1.3.2 (2005-01-23, Revision moin--main--1.3--patch-587)
  3666 
  3667 Fixes:
  3668 
  3669     * ACL bugfix for deleted pages with ACL protection.
  3670     * ACL bugfix for "Default" acl.

  3673       * Fixed traceback in RecentChanges.
  3674       * Fixed traceback with links browser.
  3675     * Fixed 0 revision display in 'Show changes'.
  3676     * Fixed traceback in Antispam which occurred when it could not connect
  3677       to MoinMaster. Log the errors to stderr or error.log.
  3678     * Fixed bug in Page init (no date, use rev). Fixes problem with
  3679       #deprecated PI.
  3680     * Fixed empty lists in empty search results.
  3681     * Cosmetic fix for modern theme (when viewed with Internet Explorer).
  3682     * Fixed migration 9 script, do not drop newline, do not drop error.log, 
  3683       note about missing error.log.
  3684     * Fixed repair_language.py script, keep ending newline on revisions.
  3685     * Show headings and macro content in correct direction when mixing content 
  3686       in several directions in the same page and using caching.
  3687     * Fixed bug in standalone re farmconfig.
  3688     * Fixed DOS condition in antispam code.
  3689     * Use smaller margin in print mode to get better results with 
  3690       Mozilla/Firefox.

  3694     * Fixed some broken tests.
  3695     * Fixed recursive include in pstats.
  3696     * Fixed bug in standalone - HTTP result code was 200 even when the access
  3697       was forbidden.
  3698     * Fixed traceback when trying to login with non-ascii password.
  3699     * Fixed traceback when xml is not available, reported on Python 2.2.?
  3700     * Fixed slideshow to show slides in sorted order again.
  3701     * Fixed serving multiple wikis on same IP/different ports with twisted and
  3702       farmconfig.
  3703     * It is possible to run with data_underlay_dir = None for special
  3704       application, but be aware that the wiki won't be usable unless you have
  3705       at least some of the system pages from underlay/ available.
  3706     * Files with Unicode characters in their filename are possible now.
  3707     * Bugfix for broken [:page#anchor:text] links.
  3708     * Workaround an instability of the gdchart module leading to
  3709       stalled servers etc.
  3710     * Fixed some event-log decoding issues that affect charts rendering.
  3711 
  3712 Other changes:
  3713 
  3714     * Major speed improvement over 1.3.1. Many times faster title search,
  3715       creating new page, opening page editor and any operation that list pages.
  3716       See http://moinmoin.wikiwikiweb.de/MoinBenchmarks
  3717     * Improved README.migration.
  3718     * Cleaner design for login/register interface, login is always the default
  3719       button when the user click Enter.
  3720     * If there are problems found in the configuration, log the error
  3721       and display helpful error messages in the browser.
  3722     * More forgiving unicode configuration policy, you must use the u'string' 
  3723       format only for unicode values.
  3724     * Added profiling to CGI.
  3725     * The content of farmconfig.py is similar to wikiconfig.py now.
  3726     * Unexpected errors while loading cache files are logged.
  3727     * i18n for icon ALT tags.
  3728     * Include request initialization code in the profile in standalone server.
  3729     * When creating new theme, style sheets are inherited correctly, no need
  3730       to override style sheets just to get them working.
  3731     * Many times faster plugin system. Typical pages are about 35% faster, 
  3732       pages with many plugins can be many times faster. 
  3733     * Spiders are allowed to fetch attachments.
  3734     * Old user files containing password hash encoded in pre 1.3 charset
  3735       are auto repaired on first login.
  3736     * data_dir defaults to './data', underlay_data_dir to './underlay' now.
  3737       It is a good idea to replace those by absolute pathes in wikiconfig.py.
  3738     * Renamed "Refresh" to "Delete Cache" - it was misused by users. The action 
  3739       was also moved into the action menu in the modern and rightsidebar themes.
  3740     * Added a workaround for TableOfContents missing some links by making it
  3741       uncacheable via a "time" dependency.
  3742     * Removed interwiki icon and title attribute for wiki:Self:... links.
  3743     * Unittests (normally shown at end of action=test output) are currently
  3744       disabled because they worked unreliably, giving wrong results sometimes.
  3745 
  3746 New features:
  3747 
  3748     * Create new pages easily using configurable interface and page templates 
  3749       with the new NewPage macro.
  3750     * ReStructuredText (rst) support is built-in now. See HelpOnParsers.
  3751     * New experimental feature in mointwisted.py - each interface may 
  3752       specify a port: '12.34.56.78:80'. Without a port, the port option
  3753       is used.
  3754 
  3755 API changes:
  3756 
  3757     * For a complete list of changes, see MoinMoin:ApiChanges.
  3758     * wikiutil.importPlugin's first argument is now a wiki config instance 
  3759       (request.cfg) and there is no path keyword.
  3760     * Wiki plugins always override MoinMoin plugins. wikiutil.importPlugin
  3761       implements this override.
  3762     * util.pysupport.importName does not accept path - you should call 
  3763       it with correct module name, e.g 'wikiconfig.plugin.parser.wiki' for 
  3764       wiki plugins, or 'MoinMoin.parser.wiki'. 
  3765     * wikiutil.extensionPlugin was renamed to wikiPlugins and it gets config 
  3766       instance instead of path.
  3767     * New function wikiutil.importWikiPlugin used to import wiki plugins 
  3768       using a cache in a thread safe way.
  3769     * New config option config.use_threads is used to activate thread 
  3770       safe code.
  3771     * New keyword arguments for getPageList, enable 10X faster operation
  3772       for common cases by controlling page filtering.
  3773     * New up to 100X times faster getPageCount
  3774 
  3775 
  3776 Version 1.3.1 (2004-12-13, Revision moin--main--1.3--patch-434)
  3777 
  3778 Fixes:
  3779 
  3780     * Fixed "Error Cyclic usage" crash when user had Italian (it), Korean
  3781       (ko), Serbian (sr) or Vietnamese (vi) as user interface language.
  3782     * Fall back to en (instead of crashing) when user uses a language moin
  3783       does not support / does not support any more (like pt,sv,fi,sr).
  3784     * In 1.3.0, people accidentally put iso-8859-1 chars into wiki configs,
  3785       but those where expected to be pure utf-8 and thus it crashed.
  3786       Fixed by using unicode strings (varname = u'whatever'), a matching
  3787       encoding setting (see top of script comment) and, when decoding strings,
  3788       using decode to ASCII with replace mode (this replaces non-ASCII chars,
  3789       but at least it won't crash - and you get a warning to better use
  3790       Unicode strings).
  3791     * Fixed long time broken table formatting. ||<style="see css spec" a||b||
  3792       Now even generates valid HTML! The old markup for align, valign, width,
  3793       bgcolor still works, but synthesizes style attribute data.
  3794     * SystemAdmin macro shows attachments of ALL pages now.
  3795     * Users without write acl rights will be able to see attachments again and
  3796       also have AttachFile action in menu.
  3797     * Fixed wrong match count in search results, find all matches in page 
  3798       titles, show all matches in contents in some rare cases.
  3799     * Run about 200% faster with long running processes (standalone, Twisted), 
  3800       about 20% faster with cgi, by better internal data handling in wikidicts.
  3801     * On SF, the dict files use utf-8 encoding now. We included them also in
  3802       distribution, see contrib/dict/.
  3803     * Fixed permissions to shared template stuff.
  3804     * Speeded up search, fixed wrong match counts.
  3805     * Speeded up internal data handling (wikidicts).
  3806     * Fixed rare unicode error after deleting a page (reported only on SuSE
  3807       Linux 9.0 / Python 2.3.0).
  3808     * Fixed file permissions of files in the data dir.  
  3809     * Fixed some cosmetic problems in migration scripts and use sys.path.insert
  3810       to get latest moin code when executing them.
  3811 
  3812 Other Changes:
  3813 
  3814     * Improved docs, system and help pages.
  3815     * Updated translation files.
  3816 
  3817 Known Bugs:
  3818 
  3819     * Internet Explorer renders our HTML/CSS in a suboptimal way.
  3820       (MoinMoin: href="http://moinmo.in/MoinMoinBugs/InternetExplorer)">MoinMoinBugs/InternetExplorer)
  3821       Workaround: use a non-broken browser like FireFox / Mozilla.
  3822       Fixed in MoinMoin 1.3.2.
  3823     * Passwords using non-ascii do not work.
  3824       (MoinMoin: href="http://moinmo.in/MoinMoinBugs/NonAsciiPasswordsBroken)">MoinMoinBugs/NonAsciiPasswordsBroken)
  3825     * The TOC macro is broken partly.

  3830 
  3831 Version 1.3.0 (2004-12-06, Revision moin--main--1.3--patch-400)
  3832 
  3833     As you see from the length of the 1.3 changes below, 1.3 is a major(!)
  3834     upgrade. We could have also named it "2.0", but we decided against.
  3835     So take the time for reading the informations thoroughly and do the
  3836     migration exactly as we tell you - this is no 5 minutes upgrade!
  3837 
  3838     !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  3839     !!! We heavily changed configuration, data encoding, dir layout:    !!!
  3840     !!!  * the default encoding changed to utf-8.                       !!!
  3841     !!!  * also, we changed the escaping for special chars to %XX%YY in !!!
  3842     !!!    URL and (xxyy) in file system.                               !!!
  3843     !!!  * layout of data dir changed completely                        !!!
  3844     !!! If you upgrade an existing wiki, you must run the migration     !!!
  3845     !!! scripts or you will get data corruption or other problems.      !!!
  3846     !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  3847 
  3848     HINT: Upgrading your wiki - critical information
  3849 
  3850       If you are NOT starting from scratch, you MUST convert your existing
  3851       data - see README.migration for details.
  3852 
  3853       If you use ##language: xx comments on your OWN pages, you should also run
  3854       repair_language script. Not needed for help/system pages as we already
  3855       have done that for you.
  3856 
  3857       MoinMoin uses Unicode internally now (UCS-2 with 16 bits or UCS-4 with
  3858       32 bits, depending on your Python installation). The encoding used
  3859       for page files and html output is set by config.charset.
  3860 
  3861       Moin 1.3 uses utf-8 encoding only, there is NO SUPPORT for using a
  3862       charset different from utf-8 with 1.3. If you try, you are on your own.
  3863 
  3864     Directory layout
  3865 
  3866       Directory layout was heavily changed. Each page now is a directory,
  3867       containing page revisions, attachments, cache files and edit-log.
  3868       
  3869       You can delete a page or move a page from one wiki to another
  3870       easily. Look at the wiki/data directory to see.
  3871       
  3872       Example:
  3873         old: data/text/FrontPage
  3874         new: data/pages/FrontPage/revisions/00000042
  3875              data/pages/FrontPage/current (contains: 00000042)
  3876         old: data/backup/FrontPage.xxxxxxxx
  3877         new: data/pages/FrontPage/revisions/00000023
  3878 
  3879       For cleaning up cache files, use MoinMoin/scripts/cachecleaner.py 
  3880       (see comments in script).
  3881 
  3882    Python / Libs
  3883       
  3884       * For using RSS, you need to have PyXML installed:
  3885         Python 2.4*   -> PyXML 0.8.4 (cvs version)
  3886         Python 2.3.x  -> PyXML 0.8.3
  3887         Python 2.2.2+ -> ???
  3888         This will also make "Live Bookmarks" of Mozilla Firefox working.
  3889         New: if you don't have PyXML installed, the RSS icon on RecentChanges
  3890         will not be displayed any more. Python with no PyXML installed
  3891         generates invalid RSS XML.
  3892 
  3893    Page names handling
  3894 
  3895       * Handling of special characters in file names changed from _xx format
  3896         to (xx...) format.
  3897       * In URLs, moin now uses %xx%yy quoting, (because this is supported by 
  3898         browsers), and sub pages use "/" instead of the ugly "_2f".
  3899       * Underscore character "_" is used now as a space character " " both 
  3900         in file names and URLs. " " and "_" will be handled equivalent at most
  3901         places in the future (represented as "_", rendered as " ").
  3902       * To prevent wiki abuse and user typing errors, page names are normalized 
  3903         in URLs, query strings, the "go" box and when renaming pages. This 
  3904         include leading, trailing and multiple slashes and white space. Certain 
  3905         invisible unicode characters are removed from page names.
  3906       * Group page names are restricted even more, any non unicode alpha-numeric
  3907         character is removed. This is done to enable changing acl syntax in 
  3908         the future. The restriction might be loosen on future versions.
  3909       * You can edit config.page_invalid_chars_regex to control which characters
  3910         are allowed in page names (Changing it is not supported).
  3911       * When you enter page name, it is normalized and you are redirected to
  3912         the normalized page, or if nothing left (e.g '/////'), to FrontPage.
  3913       * When renaming a page to a name that can be normalized to an empty string,
  3914         the new page name will be "EmptyName" and the user will not get an
  3915         error message.
  3916        
  3917    Underlay directory
  3918 
  3919      * Pages (especially system and help pages) are now located in an underlay
  3920        directory (data_underlay_dir). You will see the pages there if they are
  3921        NOT covered (overlayed) by a page in the normal pages directory
  3922        (as set using data_dir).
  3923        MAKE SURE THAT data_underlay_dir IS CORRECT OR YOU WILL SEE MANY EMPTY
  3924        PAGES ONLY IN A NEW WIKI.
  3925      * If you edit a page that is shown from underlay directory, it will be
  3926        copied to the normal page directory on save (copy-on-write).
  3927      * You can use one copy of the underlay directory shared by many
  3928        wiki instances. Each wiki will then have only your local, self-made
  3929        wiki pages in its data directory, and only system and help pages in the
  3930        single, shared underlay directory - this simplifies upgrades a lot.
  3931      * It is recommended to keep your underlay system and help pages immutable
  3932        using acl, so you can upgrade your wiki easily. The default help and
  3933        system pages already have those ACLs (using MoinPagesEditorGroup).
  3934      * Do not forget to remove your old help and system pages after migrating
  3935        your wiki. We don't provide a script for that as that would be
  3936        dangerous for edited pages. Just use some file manager (e.g. mc) to
  3937        clean the data/pages/ directory. As soon as you have removed the
  3938        system pages there, you will see the new pages in the underlay dir.
  3939        See the EditedSystemPages page for a list of pages that exist in both
  3940        data and underlay directory (use this page as admin!).
  3941 
  3942        When updating from 1.2 or lower to 1.3 or higher, you will want to
  3943        clean out the copies of the system pages in your {{{wiki/data}}}
  3944        directory. All of these pages will now reside in the underlay
  3945        directory. If you have system pages from 1.2 or lower in your
  3946        wiki/data/ directory, they will overshadow the more up-to-date
  3947        documentation. This can be done using the following manual procedure:
  3948        1. You have just converted from 1.2 or lower to post-1.3.
  3949        2. Go to your wiki's EditedSystemPages.
  3950        3. Find all the pages that are MoinMoin system or help pages. You will
  3951           know if it is one of those pages because it is not your page.
  3952        4. Check if it is okay to delete by either:
  3953           1. Using the this page "info" link and check the Revision History to
  3954              see if it is greater than 1. If so, there are modifications, so do
  3955              not delete the page and evaluate the modifications to see if they
  3956              are necessary.
  3957           2. Using your file browser (Windows Explorer, etc) to go to your
  3958              wiki/data/<<systemPage>>/revisions/ directory and to see if there
  3959              are no modifications. If there are, do not delete the page and
  3960              evaluate the modifications to see if they are necessary.
  3961        5. Delete that wiki/data/<<systemPage>> using your file browser.
  3962 
  3963     Multiple languages
  3964 
  3965       * New file name quoting method allow 50% longer page names in languages
  3966         that use more than one byte per character, like Hebrew, Korean etc.
  3967       * Configuration file uses 'utf-8' encoding now. Certain values that are
  3968         marked with [Unicode] can use any character in your language. Examples 
  3969         are page names in navi_bar, page types regular expressions and site name.
  3970       * For configuration examples adopted to your language, check ConfigMarket 
  3971         in the MoinMoin wiki.
  3972       * The system and help pages that come with moin are now in utf-8.
  3973       * MissingPage system page localized, should display in your language.
  3974       * We did many i18n (translation) updates.
  3975       * CSS file use utf-8 encoding. User css is also expected to be utf-8.
  3976         This is relevant only if you use non-ASCII values in the CSS file.
  3977       * config.upperletters and config.lowerletters were removed.
  3978         We now use a pre-made ucs-2 spanning set and you usually don't have to
  3979         change it. See MoinMoin/util/chartypes.py if you're interested.
  3980       * ACL works with any user name or group name in any language, even names 
  3981         with spaces.
  3982       * Now you can use any charset in config.charset. Note: only utf-8 is 
  3983         a supported configuration!
  3984       * Improved url handling, now creating pages directly from the browser 
  3985         url box with non-ascii names works in most cases, even when 
  3986         config.charset is not utf-8.
  3987       * When using non-utf-8 config.charset, characters in URLs that does
  3988         fit in the charsets are replaced with "?" (instead of crashing).
  3989       * All themes and most macros and actions are Right to Left friendly.
  3990         Full RTL support planned for 1.3 release.
  3991       * If page language is specified with #language processing instruction
  3992         the page is displayed in the correct direction. Pages without
  3993         language are displayed using the wiki default_lang.
  3994 
  3995     Multiple configurations
  3996 
  3997       * You can run multiple wikis from the same wiki directory or server. 
  3998         For example, you can run one Twisted server that serve multiple wikis, 
  3999         instead of running multiple servers. Samples of the new configuration
  4000         are supplied in wiki/config/*.
  4001       * You can't just use your old moin_config.py file. It is now called
  4002         wikiconfig.py and the config variables now have to be in a class
  4003         "Config" and that class must inherit from
  4004         MoinMoin.multiconfig.DefaultConfig - see the provided wikiconfig.py
  4005         sample for details.
  4006         This is very useful, e.g. you could derive a GermanConfig from
  4007         DefaultConfig. After that, you can derive configs for wikiA and wikiB
  4008         from that GermanConfig.
  4009       * farmconfig.py contains a mapping attribute called "wikis" with pairs of
  4010         wikiconfig module name and regular expression. The regular expression
  4011         is matched against the URL of the request and the first matching entry
  4012         determines the config module to be imported by MoinMoin.
  4013       * If you use farmconfig.py's "wikis" mapping, then any wiki has a private
  4014         config module, named after the wiki - e.g. wiki named moinmoin would
  4015         use moinmoin.py.
  4016       * If you only have a single wiki, you do not need farmconfig.py. just make 
  4017         a wikiconfig.py and it will be used no matter what URL is requested. 
  4018       * There is one common global "config" that holds sitewide settings (like
  4019         umask or charset) - you do not need to change settings there.
  4020         This file is located in the MoinMoin code: MoinMoin/config.py.
  4021       
  4022     General configuration
  4023 
  4024       * SecurityPolicy now uses "write" instead of "edit" (so it is may.write
  4025         now). This is to get it in sync with ACLs.
  4026       * SecurityPolicy now automatically can use everything in acl_rights_valid.
  4027       * There is a new config option "config_check_enabled". It will warn about
  4028         any unknown variable name (probably typo) to stderr or error.log. 
  4029         If something doesn't work at all and changing the config does no 
  4030         difference, switch it on and look at the error message. 
  4031       * The sample config file comes with config_check_enabled = 1. If you 
  4032         introduce additional variables yourself, you definitely want to switch 
  4033         that check off or it will fill your log.
  4034       * If you define "page_front_page" variable, this name will show in the 
  4035         navigation bar now, instead of the default "FrontPage".
  4036 
  4037     New search engine
  4038 
  4039      * Full text and title search do support multiple search terms now - 
  4040        see HelpOnSearching for details.
  4041      * Regular expressions are still supported but have to be turned on per
  4042        search term. Search terms in macros using regular expressions will have
  4043        to be fixed.
  4044      * The URL interface of the search engine has also changed. Links that 
  4045        point directly to search actions may be broken.
  4046 
  4047     User names
  4048 
  4049       * User names can not use group names, even if ACLs are not enabled.
  4050         This will prevent error later, if you start to use acl in the future
  4051         (acl is going to be mandatory in 1.5).
  4052       * User names are not restricted any more to only CamelCase. 
  4053       * To prevent imposing as other users, leading, trailing and multiple 
  4054         whitespace in user names is not allowed. Only Unicode alpha numeric 
  4055         characters are allowed, with optional one space character between 
  4056         words.
  4057       * When a user name with a group name or "bad" name is trying to 
  4058         access the wiki, he is redirected to the UserPreferences page and 
  4059         asked to create a new account.
  4060       * When trying to login or create a new account with a bad name, 
  4061         correct error message is displayed in all cases.   
  4062 
  4063     CGI
  4064 
  4065       * You can not use your old moin.cgi file, as we removed cgimain.py 
  4066         (was deprecated since 1.2). Copy the new file from the server dir.     
  4067 
  4068     Moin servers - Twisted and standalone
  4069 
  4070       * Configuration self checking on startup. Will raise an error in case
  4071         of bad configuration or non-accessible directories.
  4072       * Both use shorter and identical configuration options.
  4073       * Server scripts contain detailed comments and examples.
  4074       * Configuration defaults changed to fit most users.
  4075       * There is memory profiler option for debugging, switched off by default.
  4076       * If you perform a standard install, server scripts should run out
  4077         of the box or with minimal change.
  4078 
  4079     Twisted server
  4080 
  4081       * All code moved into the new server package, the server script
  4082         contains only configuration options.
  4083       * Listen to more than one interface with "interfaces" list.
  4084       * Code updated to new Twisted API.
  4085       * Use mointwisted script to start and stop the server, using 
  4086         "mointwisted start" and "mointwisted stop".
  4087       * The Twisted server runs as daemon by default.
  4088       * All moin Twisted files are called now mointwisted instead of 
  4089         moin_twisted.
  4090       * Fixed getting username from Twisted request (http auth)
  4091 
  4092     Standalone server
  4093 
  4094       * Configuration moved from moin_config.py to moin.py.
  4095       * If run as root, you can set both user and group for the server.
  4096       * Can use logfile instead of logging to stderr.
  4097       * Fixed missing unquoting of query string (caused problems in rare cases).
  4098 
  4099     mod_python server
  4100 
  4101      * moin_modpy server files renamed to moinmodpy.
  4102 
  4103     Wiki Markup
  4104 
  4105      * '''strong''', ''em'' and __underline__ have now paragraph scope. You can
  4106        set these attributes on words level. For multiple paragraphs, wrap each 
  4107        with needed markup.
  4108      * If you leave unclosed ''', '' and __  markup, its is closed when the 
  4109        paragraph ends.
  4110 
  4111     User interface
  4112 
  4113      * Due to many changes in CSS files, the wiki may look "broken" until
  4114        your reload once or twice, or empty your browser cache.
  4115      * The "Send mail notification" checkbox is replaced by "Trivial change"
  4116        checkbox. The default behavior did not change - regular edit is not
  4117        a trivial change, and mail will be sent to subscribes. If you check
  4118        trivial change, mail will be sent only to users who selected to 
  4119        get trivial changes in their user preferences.
  4120      * New theme "modern" has been added, and used as default theme. 
  4121      * classic and rightsidebar improved.
  4122      * viewonly theme removed, as any theme can be use now as viewonly
  4123        by using #acl All:read in the wikiconfig.
  4124      * All themes use new navibar, displaying both wiki links, user links
  4125        and the current page.
  4126      * navibar and pagetrail use now shortened page names, so very long
  4127        names does not break the interface visually.
  4128      * All themes have improved search interface at the top of the window.
  4129      * Only avaiable actions are displayed, so most situations when a user
  4130        try to do something he can't do are prevented.
  4131      * When creating a new page, no action is available until the page 
  4132        is created. You can't attach files to non-existing page any more.
  4133      * Non registered users get a "login" link. Registered uses get
  4134        "username" link to their home page, and "user preferences" link.
  4135      * Messages more clear using bold type, designed by css.
  4136      * Few useless messages removed (but there are many more)
  4137      * Default wiki logo uses the wiki name instead of the MoinMoin troll 
  4138        logo.
  4139 
  4140     Other fixes and changes
  4141     
  4142      * Most generated html code is valid "html 4 strict". There are still
  4143        some problems that still have to be fixed, mainly macros, table
  4144        attributes, and inline markup crossing (<a><b></a></b>).
  4145      * WantedPages can include and exclude system pages, which makes it 
  4146        much more useful.
  4147      * Fixed a bug in TitleIndex where not all system pages are excluded.    
  4148      * RenamePage action now renames everything, including backups, page
  4149        history, attachments. It does not change toplevel editlog, though.
  4150        After you rename a page, you are redirected to the new page.
  4151      * Syntax colorization supports more languages (Java, C++, Pascal)
  4152      * Inline: display of attachments was extended. A Parser now knows which
  4153        extensions it can handle.
  4154      * TableOfContents and Include macros now cooperate a bit better. There
  4155        are still problems with multiple Includes of the same page.
  4156      * Excluded actions at bottom of page are not displayed any more.   
  4157      * Editor: removed the columns size setting, just using 100% of browser
  4158        window width (it didn't work because of that anyway). Also removed that
  4159        "reduce editor size" link at top of editor as you would lose your
  4160        changes when using it.
  4161      * Removed the option to choose text smileys instead of images, this made
  4162        more trouble than it was worth. The text version is still given in ALT
  4163        attribute.
  4164      * Moved stuff from contribution/ to MacroMarket page on MoinMoin wiki
  4165      * Some nasty people try to use a running moin as a proxy (at least they
  4166        did on moinmaster.wikiwikiweb.de:8000, maybe due to the magic port
  4167        number). We changed the code to check for that and just return 403
  4168        in that case. Moin can not be used as a proxy anyway.
  4169      * moin.cgi?test was removed in favor of a new buildin test
  4170        action. It works for all deployments, just use ?action=test.
  4171      * Sending mail does use tls if server supports it.
  4172 
  4173     3rd party developer notes
  4174 
  4175      * Themes should be now sub class of MoinMoin.theme.ThemeBase. Sub
  4176        classes will get automatically all new improved user interface
  4177        elements for free.
  4178      * Theme authors should update their theme for 1.3. Some keys removed
  4179        from them dict. See ThemeBase class in MoinMoin/theme/__init__.py. 
  4180      * Actions writers should call request.setContentLangauge with the 
  4181        correct language used by the action. This enable themes and other
  4182        code to use correct direction.
  4183      * The Formatter interface was changed. Formatters and parsers using 
  4184        the formatter interface have to be adjusted.
  4185      * started deprecation of Processors: they are still recognized, but
  4186        implementors should start to rewrite their Processors as Parsers.
  4187        A processor with the same name as a parser in a pre #! section is
  4188        currently preferred. This will change in the next release.
  4189 
  4190     Deprecation notes
  4191 
  4192      * Processors are deprecated, see section above.
  4193 
  4194      * Using the cookie (or the login url with ID) only and not setting (or
  4195        setting and not remembering) your email/password in UserPreferences
  4196        is DEPRECATED. Those quite unsecure methods will likely be dropped
  4197        in next moin version.
  4198 
  4199      * Operating with acl_enabled = 0 is also DEPRECATED. Due to some other
  4200        improvements planned, we will have to operate with ACLs enabled ONLY
  4201        in a future moin version, so this setting will likely be dropped.
  4202        So clean up your user accounts (see moin_usercheck.py) and switch ACLs
  4203        on NOW.
  4204        There are no drawbacks, so you will like it. Having ACLs enabled
  4205        doesn't mean you really have to USE them on wiki pages...
  4206 
  4207      * allow_extended_names = 0 is deprecated (default was/is 1).
  4208        Future versions will be able to use extended names (aka free links) in
  4209        any case and the config setting will be removed.
  4210 
  4211      * allow_subpages = 0 is deprecated (default was/is 1).
  4212        Future versions will be able to use subpages in any case and the config
  4213        setting will be removed.
  4214 
  4215      * attachments = {...} - we would like to remove that setting because of
  4216        several reasons:
  4217        * when not being extremely careful, this can easily lead to security
  4218          problems (like when uploading a .php exploit and then executing it
  4219          by accessing it directly via web server)
  4220        * makes code more complicated - code that we want to change completely
  4221          in next version
  4222        If you need that feature, speak up now and tell us your reasons WHY you
  4223        need it.
  4224 
  4225 
  4226 Version 1.2.4 (2004-10-23, Revision 1.187)
  4227 
  4228 This will probably be the last 1.2.x release as we are soon doing release
  4229 candidates for 1.3 release (with big internal changes) and are expecting
  4230 release 1.3 in december 2004.
  4231 
  4232 Fixes:
  4233     * fixed "None" pagename bug in fullsearch/titlesearch
  4234     * fixed projection CSS usage
  4235     * the compiled page is removed when a page is deleted, so no ghost page
  4236       appears after deletion
  4237     * fixed AbandonedPages day-break problem
  4238     * fixed [[GetVal(WikiDict,key)]]
  4239     * the msg box is now outside content div on PageEditor, too
  4240     * privacy fix for email notifications: you don't see other email addresses
  4241       in To: any more. mail_from is now also used for To: header field, but
  4242       we don't really send email to that address.
  4243     * privacy fix for /MoinEditorBackup pages that were made on previews of
  4244       pages that were not saved in the end
  4245     * fix double content div on PageEditor preview
  4246 
  4247 Other changes:
  4248     * workaround for broken Microsoft Internet Explorer, the page editor now
  4249       stops expanding to the right (e.g. with rightsidebar theme).
  4250       Nevertheless it is a very good idea to use a non-broken and more secure
  4251       browser like Mozilla, Firefox or Opera!
  4252 
  4253     * from MoinMoin.security.antispam import SecurityPolicy in your
  4254       moin_config.py will protect your wiki from at least the known spammers.
  4255       See MoinMoin:AntiSpamGlobalSolution for details.
  4256 
  4257     * xmlrpc plugin for usage logging, currently used for antispam accesses
  4258 
  4259     * (re-)added configurable meta tags:
  4260         * html_head_queries = '''<meta name="robots" content="noindex,nofollow">\n'''
  4261         * html_head_posts   = '''<meta name="robots" content="noindex,nofollow">\n'''
  4262         * html_head_index   = '''<meta name="robots" content="index,follow">\n'''
  4263         * html_head_normal  = '''<meta name="robots" content="index,nofollow">\n'''
  4264 
  4265     * i18n updates/fixes
  4266 
  4267     * New UserPreferences switch:
  4268       you may subscribe to trivial changes (when you want to be notified about ALL
  4269       changes to pages, even if the author deselected to send notifications).
  4270 
  4271     * New AttachList and AttachInfo macros - thanks to Nigel Metheringham and
  4272       Jacob Cohen.
  4273 
  4274 Version 1.2.3 (2004-07-21, Revision 1.186)
  4275 
  4276 Fixes:
  4277     * fixed NameError "UnpicklingError" in user.py
  4278     * fixed version number in moin.spec
  4279     * reverts done by bots or leechers
  4280       There was a bad, old bug that triggered if you did not use ACLs. In that
  4281       case, moin used some simple (but wrong and incomplete) function to
  4282       determine what a user (or bot) may do or may not do. The function is now
  4283       fixed to allow only read and write to anon users, and only delete and
  4284       revert to known users additionally - and disallow everything else.
  4285     * avoid creation of unneccessary pages/* directories
  4286     * removed double content divs in general info and history info pages
  4287     * fixed wiki xmlrpc getPageHTML
  4288     * fixed rightsidebar logout URL, also fixed top banner to link to FrontPage
  4289     * use config.page_front_page and .page_title_index for robots meta tag
  4290       (whether it uses index,follow or index,nofollow), not hardcoded english
  4291       page names
  4292     * ACL security fix for PageEditor, thanks to Dr. Pleger for reporting
  4293     * default options for new users are same as for anon users
  4294 
  4295 Version 1.2.2 (2004-06-06, Revision 1.185)
  4296 
  4297 Fixes:
  4298     * python related:
  4299      * own copy of difflib removed
  4300        Until moin 1.2.1 we had our own copy of python 2.2.3's difflib coming
  4301        with moin. This was to work around some problems with broken older 2.2
  4302        python installations. We removed this now because if you have py 2.3,
  4303        there is even a better difflib coming with python (and that fixes an
  4304        extremely slow diff calculation happening in some rare cases).
  4305        So the good news is that when you run python 2.3, you don't need to do
  4306        anything and it will run great. If you run python 2.2.3, it will mostly
  4307        work good and you also don't need to do anything. The bad news is that
  4308        if you run an old and broken 2.2 installation (2.2.1, maybe 2.2.2) you
  4309        will have to fix it on your own (just copy difflib.py from python 2.2.3
  4310        over to your python 2.2.x installation).
  4311        But better upgrade to python 2.3 (for debian woody, there's a backport),
  4312        as 2.3 generally runs better and faster than 2.2.
  4313      * scripts changed to use #!/usr/bin/env python (not /usr/bin/python2.2)
  4314 
  4315     * user accounts and ACLs:
  4316      * we now require the user to specify a password for a new account (you
  4317        were not able to login without a password anyway)
  4318      * it is not allowed any more to create user accounts with user names
  4319        matching config.page_group_regex - please check manually that you do
  4320        not already have such users existing (like a user named "AdminGroup"):
  4321        cd data/user ; grep name=.*Group *  # there should be no output!
  4322      * subscription email sending now honours ACLs correctly
  4323 
  4324     * markup / rendering / user interface fixes:
  4325      * fixed merging multiple lines indented by the same amount of blanks
  4326      * ## comments don't break tables in two parts
  4327      * added a "remove bookmark" link to RecentChanges
  4328      * fixed action=titleindex (added \n after each entry)
  4329 
  4330     * RSS fixes:
  4331      * non-ASCII characters should work now
  4332      * RSS feed (Recentchanges?action=rss_rc) gives UTC timestamps now
  4333      * removed attribute breaking RSS feed on RecentChanges
  4334 
  4335     * better email generation:
  4336      * if you use python >=2.2.2, we add a Message-ID header to emails
  4337      * if you use python 2.2.1, there is no email.Header. Instead of crashing
  4338        (like previous moin 1.2.x releases), we just use the subject "as is" in
  4339        that case. If it is not ASCII, this is not standards compliant.
  4340      * If you have >=2.2.2 it will use email.Header to make standards compliant
  4341        subject lines.
  4342      * use config.mail_from as sender address when sending "lost my password"
  4343        emails
  4344 
  4345     * file attachments:
  4346      * fixed for standalone server
  4347      * attachment URLs (when handled by moin) don't include server name
  4348      * fixed some wrong &amp;amp; in html src
  4349     
  4350     * better themeability:
  4351      * some entries in dict "d" where only present in header theme calls, some
  4352        only in footer theme calls. Now almost all is present in both calls.
  4353      * added some missing "content" divs so sidebar themes look better
  4354 
  4355     * fixed some crashes producing backtraces:
  4356      * no IOError when diffing against deleted page
  4357      * no backtrace in xml footnote generation
  4358      * no SystemInfo crash when no editlog exists in new wikis
  4359      * xmlrpc.getRecentChanges fixed
  4360 
  4361     * MoinMoin.util.filesys.rename is now a wrapper around os.rename that
  4362       fixes os.rename on broken win32 api semantics
  4363 
  4364 Other Changes:
  4365     * saving traffic and load by improved robot meta tag generation:
  4366      * "noindex,nofollow" on queries and POSTs
  4367      * "index,follow" on FrontPage and TitleIndex (give robots a chance ;))
  4368      * "index,nofollow" on all other pages (hopefully saving lots of senseless
  4369        requests for page?action=...) 
  4370      * removed config.html_head_queries (was used for same stuff)
  4371     * added russian i18n (utf-8)
  4372     * misc. other translation updates / fixes
  4373     * added rightsidebar theme
  4374     * TitleIndex now folds case, so "APage" and "anotherPage" are both under
  4375       letter "A".
  4376     * added macro/PageHits.py - it calculates the hits each page gets since
  4377       beginning of logging
  4378 
  4379 
  4380     * Full text and title search do now support multiple search terms - 
  4381       see HelpOnSearching for details
  4382  
  4383     * The Formatter interface was changed. Formatter and parser using 
  4384       the formatter interface have to be adjusted.
  4385 
  4386 Version 1.2.1 (2004-03-08, Revision 1.184)
  4387 
  4388 Fixes:
  4389     * minimum requirement to run moin 1.2/1.2.1 is python 2.2.2
  4390      * not: 2.2(.0), as this does not have True/False
  4391      * not: 2.2.1, as this does not have email.Header. You maybe can work
  4392        around that one by:
  4393       * getting the python 2.2.x (x>=2) /usr/lib/python2.2/email directory
  4394       * putting it into directory 'x' (whereever you like)
  4395       * doing a sys.path[0:0] = ['x'] in moin.cgi [or other appropriate place]
  4396       No guarantee, this is untested.
  4397     * Twisted: the http headers missed the charset data, fixed
  4398     * mod_python: fixes for mod_python 2.7
  4399     * wiki/data/plugin/__init__.py added - fixes not working plugin modules
  4400     * plugin processors work now, too
  4401     * fixed displaying non-existent translations of SiteNavigation in footer
  4402     * fixed zh-tw iso name (wrong zh_tw -> correct zh-tw)
  4403     * fixed reversed diffs in RecentChanges RSS
  4404     * fixed "last change" info in footer (wasn't updated)
  4405     * fixed event.log missing pagename (and other) information
  4406     * fixed horizontal line thickness >1
  4407     * fixed setup.py running from CVS workdir
  4408     * fixed crash when doing action=info on first revision of a page
  4409     * fixed hostname truncation in footer
  4410     * minor css fixes
  4411     * fixed clear msg links (they missed quoting, leading to strange page
  4412       names when you click on some of them)
  4413     * fixed python colorizer processor
  4414     * fixed quoting of stats cache filenames
  4415     * catched "bad marshal data" error when switching python versions
  4416 
  4417 Other changes:
  4418     * updated danish (da) i18n
  4419     * updated japanese (ja) i18n
  4420     * added serbian (sr) i18n
  4421     * added chinese (zh) i18n
  4422     * added a simple "viewonly" theme based on classic theme - you can use
  4423       this as default theme, so anonymous users won't get the usual wiki stuff,
  4424       but a far simpler (and less powerful) user interface.
  4425       It also displays the navibar at the left side.
  4426     * added moin.spec for building RPMs
  4427     * included MoinMoin/i18n/* into distribution archive (nice for translators)
  4428     * included some stuff under MoinMoin/scripts - xmlrpc-tools and account
  4429       checking stuff. removed some version control clutter from the dist
  4430       archive, too.
  4431 
  4432     * code colorization was refactored and some new languages (Java, C++,
  4433       Pascal) where added.
  4434     * inline: display of attachments was extended. A Parser now knows which
  4435       extensions it can handle.
  4436 
  4437 Version 1.2 (2004-02-20, Revision 1.183)
  4438 
  4439 New features:
  4440     * MoinMoin now requires Python >=2.2.2., we recommend to use Python >=2.3.2
  4441       (with 2.3.x, MoinMoin runs about 20-30% faster).
  4442     * by refactoring request processing, we made it possible to run moin under
  4443       persistent environments:
  4444         * twisted-web (http://twistedmatrix.com)
  4445         * httpdmain.py (use moin.py for starting this mini server)
  4446         * mod_python
  4447         * FastCGI
  4448       Of course, CGI is still possible.
  4449     * wiki pages will be compiled to bytecode now (by default), so no need for
  4450       slow parsing/formatting on every view ("WASP", see caching_formats)
  4451     * when using a persistent environment (like twisted) and WASP, you get up
  4452       to 20x speed - compared to CGI and moin 1.1
  4453     * added support for diffs between arbitrary revisions.
  4454     * removed requirement of the external diff utility
  4455     * config.auth_http_enabled (defaults to 0) - use this to enable moin
  4456       getting your authenticated user name from apache (http basic auth,
  4457       htpasswd) - if you enable this, your basic auth username has to be the
  4458       same as your wiki username.
  4459       Should work with CGI, FCGI and maybe even with mod_python.
  4460       Does not change behaviour of moin under twisted or standalone server.
  4461     * config.tz_offset = 0.0 sets a default timezone offset (in hours
  4462       from UTC)
  4463     * config.cookie_lifetime (int, in hours, default 12) sets the lifetime of
  4464       the MOIN_ID cookie:
  4465         == 0  --> cookie will live forever (no matter what user has configured!)
  4466         > 0   --> cookie will live for n hours (or forever when "remember_me")
  4467         < 0   --> cookie will live for -n hours (forced, ignore "remember_me"!)
  4468     * added themeing and some themes (if you improve the existing themes or
  4469       make nice new ones, please contribute your stuff!). The default theme is
  4470       set by config.theme_default (and defaults to 'classic').
  4471     * now supporting plugin directory for parsers, processors, themes, xmlrpc.
  4472     * action=info now defaults to showing page revision history again
  4473     * all actions accessing the logfile (as RecentChanges or history) are now
  4474       much faster
  4475     * #refresh processing instruction, config.refresh
  4476         * config.refresh = (minimum_delay, target_allowed)
  4477             * minimum delay is the minimum waiting time (in seconds) allowed
  4478             * target_allowed is either 'internal' or 'external', depending on
  4479               whether you want to allow only internal redirects or also
  4480               external ones. For internal redirects, just use the Wiki pagename,
  4481               for external, use http://... url.
  4482         * #refresh 3                    == refresh this page every 3 seconds
  4483         * #refresh 5 FrontPage          == internal redirect to FrontPage in 5s
  4484         * #refresh 5 http://google.com/ == redirect to google in 5s
  4485       Use very carefully! Allowing a low minimum_delay and putting a #refresh
  4486       on RecentChanges might slow down your wiki significantly, when some
  4487       people just let their browser refresh and refresh again. Also, it does
  4488       cause quite some traffic long-term. So better do not use this without
  4489       good reason! Default is None (switched off).
  4490     * hide most UserPreferences options before user has logged in, less
  4491       confusing for new users
  4492     * "config.page_dict_regex" defines what pages are dictionary definitions
  4493       Currently dictionaries are used for UserHomePage/MyDict where you can
  4494       define key:: value pairs that get processed like @DATE@ expansion when
  4495       saving a page. The 2 "@" will be added to your keys automatically.
  4496       Please do not use @xxx@ strings on the right side (value), results may
  4497       vary if you do.
  4498       You can also access wiki dictionaries by using the internal macro
  4499       [[GetVal(page,key)]]" - that will go to page "page" and return the
  4500       value (right side) corresponding to "key".
  4501       Implementation note: groups are a subset of the dictionary functionality.
  4502     * standalone server should work now (see server/moin.py), so you don't
  4503       need to setup apache or twisted for a local personal wiki, you only need
  4504       python and moin for that now, no additional stuff any more!
  4505     * if you run your wiki with charset = "utf-8" (the default is still
  4506       iso8859-1), you might want to have a look at contributions/utf8-pages/
  4507       to see if there are already translated system pages for your language.
  4508 
  4509 Fixes:
  4510     * new importPlugin routine (the old one didn't work correctly)
  4511     * removed 0xA0 characters breaking utf-8
  4512     * system page recognition now uses wiki groups (see AllSystemPagesGroup),
  4513       fixing the long-time broken system page exclusion on TitleIndex.
  4514     * mostly HTML 4.01 Strict compliant HTML
  4515     * design is done by CSS now, HTML is semantic markup only 
  4516     * removed target attribute from links, also [^NewWindow] markup - this
  4517       is a HTML 3.2 feature and not valid in HTML 4.01
  4518     * updated TWikiDrawPlugin to 20021003 version, with further modifications
  4519       including source. It can draw imagemaps now and saves PNG. On display a
  4520       GIF will be searched if no PNG is found. We recommend changing all GIFs
  4521       to indexed PNGs cause this fallback might disappear in later versions.
  4522 
  4523       Sample code using bash and ImageMagick (be sure you know what you do):
  4524       for draw in `find /path/to/wiki/data -name \*.draw`; do
  4525         file=`dirname $draw`/`basename $draw .draw`
  4526         if [ -e "${file}.gif" ]; then
  4527           echo "Converting ${file}.gif to ${file}.png"
  4528           convert "${file}.gif" "${file}.png"
  4529         fi
  4530       done
  4531 
  4532     * fixed email headers and encoding
  4533     * Changed moin-usercheck to adhere to scripting standards; no
  4534       proprietary config changes needed any more (added --config);
  4535       --wikinames is now part of the usage message.
  4536     * config.umask now defaults to 0770 - if you give world r/w access, ACLs
  4537       could be rather pointless...
  4538 
  4539 Removed config variables:
  4540     * external_diff (not needed any more, we have internal diff now)
  4541     * shared_metadb (wasn't implemented for long - we will re-add it, when it is)
  4542     * title1/2 (please use page_header1/2)
  4543     * page_icons_up
  4544 
  4545 Changed config variables:
  4546     * changed_time_fmt (removed some html and brackets around time from default)
  4547     * html_head (default is empty string now)
  4548     * page_footer1/2 (default is empty string now)
  4549     * page_icons (is now a list of icon names, not html any more)
  4550     * umask (default is 0770 now, not world r/w any more == more secure)
  4551 
  4552 New config variables (see MoinMaster:HelpOnConfiguration):
  4553     * cookie_lifetime
  4554     * mail_login
  4555     * page_credits
  4556     * page_dict_regex
  4557     * page_group_regex
  4558     * page_header1/2
  4559     * page_iconbar 
  4560     * page_icons_table
  4561     * page_license_enabled
  4562     * page_license_page
  4563     * theme_default
  4564     * theme_force
  4565     * tz_offset 
  4566 
  4567 Other:
  4568     * lots of internal code refactoring and optimization
  4569     * began moving src code documentation to epydoc, see "make epydoc"
  4570     * the URL for the RecentChanges RSS feed changed. It now only works with
  4571       ...?action=rss_rc.
  4572 
  4573 Known problems:
  4574     * theme support is neither complete (although covering most important
  4575       stuff) nor perfect - work on that will continue...
  4576     * we removed some html from system messages (the boxes at top of page you
  4577       get after some actions), so it currently looks less nice than before.
  4578     * html is not completely validating and it is not xhtml - this will be
  4579       fixed as soon as we have the infrastructure for that (other parser, DOM)
  4580     * problems with rtl (right-to-left) languages, will be fixed in 1.3
  4581     * if you change moin_config or switch themes, moin will still use already
  4582       cached page content. For the config this can be fixed by touching
  4583       MoinMoin/version.py (or simply deleting everything in
  4584       data/cache/Page.py). If you get more annoyed by this than pleased by
  4585       caching speedup, you can also switch off caching (see docs on
  4586       caching_formats).
  4587 
  4588 Themeing and HTML/CSS cleanup:
  4589     * Browsers with completely broken CSS support (like e.g. Netscape 4.x) are
  4590       no longer supported. If you still need to support them, do not upgrade to
  4591       moin 1.2. If you still use these browsers, we recommend that you upgrade
  4592       your browser first (Mozilla 1.5 has nice and standards compliant HTML and
  4593       CSS support and is available as Free Software for Windows, Linux and Mac).
  4594     * If you changed any html in code or by config you will have to check if it
  4595       still works. For the usual stuff, look into `MoinMoin/theme/classic.py`
  4596       and `classic/css/screen.css`. For config defaults of the html fragments,
  4597       read `MoinMoin/config.py`. If you want to modify a theme, don't simply
  4598       change classic, but copy or subclass it under a new theme name.
  4599     * because of the new theme support the layout of the `htdocs` directory
  4600       changed:
  4601       * Instead of using icons under `img/` and css under `css/`, there will
  4602         be an additional `themename/` directory in between, e.g. `classic/img/`
  4603         and `classic/css/`. If you added own icons, you may have to copy them
  4604         to the themes directory.
  4605       * The filename of the CSS file has changed to the media type, so the
  4606         normal one used for screen output has changed name from `moinmoin.css`
  4607         to `screen.css`. There also were quite some changes and enhancements to
  4608         the CSS files, so better use the new ones.
  4609     * config.css_url was removed
  4610 
  4611 Plugins:
  4612   * we use a new plugin loader that requires a correct `__init__.py` file in
  4613     the plugin directories. See the directory `wiki/data/plugin/` in the
  4614     distribution archive and just copy it over to your wiki's plugin directory.
  4615 
  4616 
  4617 Version 1.1 (2003-11-29, Revision 1.178)
  4618 
  4619 Version 1.1 requires Python 2.0 or higher, we recommend to use Python 2.2
  4620 (version 2.2.2 if that is available on your host) or even better >= 2.3.2
  4621 (with 2.3.x, MoinMoin runs about 20-30% faster).
  4622 
  4623 New features:
  4624   Configuration:
  4625     * config.default_lang lets you set a default language for users not
  4626       having specified language in their browser or UserPreferences
  4627     * "config.page_category_regex" defines what pages are categories
  4628     * replaced `config.page_template_ending` by a more flexible setting
  4629       named `config.page_template_regex`
  4630     * the same with config.page_form_regex (was: page_form_ending)
  4631     * "config.page_group_regex" defines what pages are group definitions
  4632       Currently groups are used for "user groups" (see ACLs) and "page
  4633       groups" (see AllSystemPagesGroup).
  4634     * robot exclusion from all pages except the standard view action,
  4635       via the config.ua_spiders regex (reduces server load)
  4636     * "maxdepth" argument for the TableOfContents macro
  4637     * config.title1, config.title2, config.page_footer1,
  4638       config.page_footer2 can now be callables and will be called with
  4639       the "request" object as a single argument (note that you should
  4640       accept any keyword arguments in order to be compatible to future
  4641       changes)
  4642     * "config.html_pagetitle" allows you to set a specific HTML page
  4643       title (if not set, it defaults to "config.sitename")
  4644     * navi_bar / quicklinks can now contain free-form links, i.e.
  4645       entries of the form "[url linktext]" just like in wiki pages
  4646     * if a quick link starts with '^', it opens in a new window; help
  4647       now opens in a new window also
  4648     * `config.smileys` for user-defined smileys (default: `{}`) - a dict
  4649       with the markup as the key and a tuple of width, height, border, image
  4650       name as the value).
  4651     * `config.hosts_deny` to forbid access based on IP address
  4652     * `config.mail_login` can be set to username and password separated by
  4653       a space, e.g. "username userpass", if you need to use SMTP AUTH
  4654     * `config.edit_locking` can be set to None (old behaviour, no
  4655       locking), 'warn <timeout mins>' (warn about concurrent edits, but
  4656       do not enforce anything), or 'lock <timeout mins>' (strict locking)
  4657     * optionally showing a license text on editor page, use:
  4658       config.page_license_enabled = 1
  4659       Optionally use these to customize what is shown there:
  4660       config.page_license_text = "... your text ..."
  4661       config.page_license_page = "MyLicensePage"
  4662       See the default values in MoinMoin/config.py for details and
  4663       override them in moin_config.py, if needed.
  4664     * `config.shared_intermap` can be a list of filenames (instead of a
  4665       single string)
  4666     * If you have added your own `SecurityPolicy`, the class interface for
  4667       that has changed (see `security.py`).
  4668 
  4669   Authenticaton / Authorization:
  4670     * added ACL support, written by Gustavo Niemeyer of Conectiva and
  4671       Thomas Waldmann. See HelpOnAccessControlLists for more infos.
  4672       You should use MoinMoin/scripts/moin_usercheck.py before activating
  4673       ACLs or some users with bad or duplicate accounts might get into
  4674       trouble.
  4675     * A user account can be disabled using moin_usercheck.py or
  4676       UserPreferences page. Disabling, but keeping it is good for edit
  4677       history.
  4678     * changed security default: deletion only available to known users
  4679     * support for Basic authentication (Apache style: AUTH_TYPE="Basic",
  4680       REMOTE_USER="WikiUserName"). If authentication is there, user
  4681       will be in ACL class "Trusted".
  4682     * support for username / password login
  4683       The username / password login will ONLY work, if you define a
  4684       password. With an empty password, username / password login is not
  4685       allowed due to security reasons. Passwords are stored encrypted
  4686       (format similar to Apache SHA) and can also be entered in the
  4687       UserPreferences form in this format. When requesting login
  4688       information by email, the password is also sent in this encrypted
  4689       format (use copy&paste to fill it in the form).
  4690       ...?action=userform?uid=<userid> is still possible, so if you have
  4691       bookmarks, they will still work). The input field for the ID was
  4692       dropped.
  4693       NOTE: using the userid for login purposes is DEPRECATED and might
  4694             be removed for better security soon.
  4695     * after logging in, you will get a cookie valid until midnight.
  4696       The next day, the cookie will expire and you will have to login
  4697       again. If you don't want this, you can check the "remember me
  4698       forever" option in UserPreferences.
  4699     * if the page file is read-only, you get a message (i.e. you can now
  4700       protect pages against changes if you're the wiki admin).
  4701       Note: you can do that easier using ACLs.
  4702 
  4703   Markup / Macros / Actions:
  4704     * RandomQuote macro (and even parses Wiki markup now)
  4705     * `[[Navigation]]` macro for slides and subpage navigation
  4706     * [[ShowSmileys]] displays ALL smileys, including user-defined ones
  4707     * the Include macro has new parameters (from, to, sort, items) and
  4708       is able to include more than one page (via a regex pattern)
  4709     * `MailTo` macro for adding spam-safe email links to a page
  4710     * if a fancy link starts with '^' (i.e. if it has the form
  4711       "[^http:... ...]"), it's opened in a new window
  4712      * because of that, the NewWindow macro was removed from contrib
  4713     * "#pragma section-numbers 2" only displays section numbers for
  4714       headings of level 2 and up (similarly for 3 to 6)
  4715     * ../SubPageOfParent links
  4716 
  4717   User interface:
  4718     * new fancy diffs
  4719     * Page creation shows LikePages that already exist
  4720     * editor shows the current size of the page
  4721     * editor returns to including page when editing an included page
  4722     * Visual indication we're on the editor page (new CSS style)
  4723     * selection to add categories to a page in the editor (use preview
  4724       button to add more than one category)
  4725     * if user has a homepage, a backup of save/preview text is saved as
  4726       a subpage UsersHomePage/MoinEditorBackup
  4727     * added "revert" link to PageInfo view (which makes DeletePage more
  4728       safe in public wikis, since you can easily revive deleted pages
  4729       via revert)
  4730     * Selection for logged in users (i.e. no bots) to extend the listing
  4731       of recent changes beyond the default limits
  4732     * Activated display of context for backlinks search
  4733     * Subscriber list shown on page info
  4734     * LikePages shows similar pages (using difflib.get_close_matches)
  4735     * last edit action is stored into "last-edited" file, and
  4736       displayed in the page footer
  4737     * reciprocal footnote linking (definition refers back to reference)
  4738     * "Ex-/Include system pages" link for title index
  4739       Note: system/help pages algorithm is still mostly broken.
  4740     * list items set apart by empty lines are now also set apart
  4741       visually (by adding the CSS class "gap" to <li>)
  4742     * "save" check for security.Permissions
  4743     * Added Spanish, Croatian and Danish system texts
  4744     * Added flag icons for the languages supported in "i18n"
  4745     * updated help and system pages, more translations, see also
  4746       AllSystemPagesGroup
  4747     * there was quite some work done on wiki xmlrpc v1 and v2 - it
  4748       basically works now.
  4749 
  4750   Tools and other changes:
  4751     * moin-dump: New option "--page"
  4752     * there are some scripts MoinMoin/scripts/* using wiki xmlrpc for

  4786 
  4787 -----------------------------------------------------------------------------
  4788 Version 1.0 (2002-05-10, Revision 1.159)
  4789 
  4790 THIS IS THE LAST RELEASE WITH PYTHON 1.5.2 SUPPORT! If severe bugs
  4791 should occur, a maintenance release will fix them.
  4792 
  4793 Some optional features (like statistics) already require Python 2.0.
  4794 
  4795 New features:
  4796     * security fix: "allow_xslt" has to be set to 1 in order to enable
  4797       XSLT processing; note that this defaults to 0 because XSLT is able
  4798       to insert arbitrary HTML into a wiki
  4799     * "action=content" for transclusion into static web pages; emits the
  4800       pure page content, without any <html>, <head>, or <body> tags
  4801     * "?action=links&mimetype=text/plain" works like MeatBall:LinkDatabase
  4802     * "Preferred language" and "Quick links" user settings
  4803     * Added "processor" concept, processors work on the data in "code
  4804       displays" and are called by a bangpath in the first line of data
  4805     * Processors: Colorize, CSV (see HelpOnProcessors)
  4806     * New icons: "{OK}", "(./)", "{X}", "{i}", "{1}", "{2}" and "{}"
  4807       (see HelpOnSmileys)
  4808     * FullSearch now displays context information for search hits
  4809     * DeletePage offers a textentry field for an optional comment
  4810     * Email notifications are sent in the user's language, if known from
  4811       the preferences
  4812     * @PAGE@ is substituted by the name of the current page (useful
  4813       for template pages)
  4814 
  4815 Unfinished features:
  4816     * user defined forms
  4817     * XML export of all data in the wiki
  4818     * RST parser (you need to install docutils to use this)
  4819     * XMLRPC interface
  4820 
  4821 Bugfixes:
  4822     * Syntax warning with Python 2.2 fixed
  4823     * Macro-generated pagelinks are no longer added to the list of links
  4824     * error codes returned by "diff" are reported
  4825     * fix for attachments on pages with non-USASCII names
  4826     * correct handling of spaces in attachment filenames and URLs
  4827 
  4828 -----------------------------------------------------------------------------
  4829 Version 0.11 (2002-03-11, Revision 1.151)
  4830 
  4831 Most important new features: file attachments, definition list markup
  4832 (glossaries), change notification via email, variable substitution when
  4833 saving pages, edit preview, and improved documentation.
  4834 
  4835 Note that the RSS features require a recent PyXML (CVS or 0.7) due to
  4836 bugs in the namespace handling of xml.sax.saxutils in earlier versions.
  4837 This is (hopefully) automatically detected on every installation.
  4838 
  4839 Statistical features are NOT designed to work with Python 1.5.2 and
  4840 require Python 2.0 or higher. Overall, MoinMoin 0.11 is not explicitely
  4841 tested for 1.5.2 compatibility.
  4842 
  4843 New features:
  4844     * XML formatting now (most often) produces well-formed, and, depending
  4845       on proper layout of the wiki page, valid StyleBook XML
  4846     * Headers are now automatically numbered, unless you set the config
  4847       item 'show_section_numbers' to 0
  4848     * "#pragma section-numbers off" (or "0") switches that off explicitely,
  4849       and "on" or "1" enables numbering 
  4850     * Added a "contributions" directory for 3rd party extensions
  4851     * AttachFile action, contributed by Ken Sugino; note that you have
  4852       to enable this action because of the possibility of DoS attacks
  4853       (malicious uploads), by adding this to your moin_config:
  4854             allowed_actions = ['AttachFile']
  4855     * "attachment:" URL scheme allows access to attachments, to get files
  4856        from other pages use "attachment:WikiName/filename.ext".
  4857     * New macros: Date(unixtimestamp) and DateTime(unixtimestamp) to
  4858       display a timestamp according to system/user settings
  4859     * Variable substitution when a page is saved, note that saving
  4860       template pages does NOT expand variables. Supported are:
  4861         @DATE@      Current date in the system's format
  4862         @TIME@      Current date and time in the user's format
  4863         @USERNAME@  Just the user's name (or his domain/IP)
  4864         @USER@      Signature "-- loginname"
  4865         @SIG@       Dated Signature "-- loginname date time"
  4866         @MAILTO@    A fancy mailto: link with the user's data  
  4867     * Copied some new emoticons from PikiePikie
  4868         || {{{ :-? }}} || :-? || tongue.gif ||
  4869         || {{{ :\  }}} || :\  || ohwell.gif ||
  4870         || {{{ >:> }}} || >:> || devil.gif  ||

  4873         || {{{ |)  }}} || |)  || tired.gif  ||
  4874         || {{{ ;)) }}} || ;)) || lol.gif    ||
  4875     * AbandonedPages macro
  4876     * Added definition list markup: {{{<whitespace>term:: definition}}}
  4877     * Added email notification features contributed by Daniel Sa�    * SystemInfo: show "Entries in edit log"
  4878     * Added "RSS" icon to RecentChanges macro and code to generate a
  4879       RecentChanges RSS channel, see
  4880           http://www.usemod.com/cgi-bin/mb.pl?UnifiedRecentChanges
  4881       for details
  4882     * Added config.sitename and config.interwikiname parameter
  4883     * Better WikiFarm support:
  4884       * <datadir>/plugin/macro and <datadir>/plugin/action can be used
  4885         to store macros and actions local to a specific wiki instance
  4886       * config.shared_intermap can contain a pathname to a shared
  4887         "intermap.txt" file (i.e. one stored outside the datadir)
  4888     * added `backtick` shortcut for {{{inline literal}}} (has to be
  4889       enabled by "backtick_meta=1" in the config file); note that ``
  4890       is then a shorter replacement for '''''' escaping
  4891     * added inline search fields (at the bottom of each page)
  4892     * Added preview to the editor, including spell checking
  4893     * New languages: Chinese (Changzhe Han) and Portuguese (Jorge
  4894       Godoy), updated French (Lucas Bruand), added Korean (Hye-Shik
  4895       Chang) and Italian (Lele Gaifax)
  4896     * New SystemAdmin macro
  4897     * `[[Anchor(anchorname)]]` macro to insert anchors into a page,
  4898       and [#anchorname Anchor Links].
  4899     * User option to open editor view via a double-click
  4900     * Added commentary field to editor, recent changes and page info
  4901     * Page trails (user option)
  4902     * UserPreferences: checkboxes for double-click edit, page trail,
  4903       fancy links, emoticons, jump to last page visited, and some
  4904       other yes/no options
  4905     * "config.nonexist_qm" is now the default for a user setting
  4906     * `[[GetText(text)]]` macro loads I18N texts (mainly intended
  4907       for use on Help pages)
  4908     * table attributes via "||<attrlist> ... ||", more details on
  4909       http://purl.net/wiki/moin/HelpOnTables
  4910     * PythonFaq interwiki tag and support for $PAGE placeholder
  4911     * event logging, as the basis for future statistics
  4912     * "moin-dump" command line tool to create a static copy of
  4913       the wiki content
  4914     * "config.external_diff" allows to set an exact path to the
  4915       command, or change the name to for example "gdiff" if GNU
  4916       diff is not a native command in your UNIX flavour
  4917     * `[[PageSize]]` macro
  4918     * the interwiki name "Self" now always points to the own wiki
  4919     * config.title1 and config.title2 are inserted into the output
  4920       right before and after the system title html code (title1
  4921       is right after the <body> tag and normally undefined, title2
  4922       defaults to the "<hr>" above the page contents)
  4923     * Additional link on diff pages to ignore whitespace changes
  4924     * Subpages (config.allow_subpages, config.page_icons_up)
  4925     * super^script^, sub,,script,, and __underline__ markup
  4926     * `[[FootNote]]` macro
  4927     * many other new config options, see HelpOnConfiguration for
  4928       a complete list
  4929     * [[StatsChart(type)]] shows statistical charts (currently
  4930       defined types: hitcounts, pagesize, useragents)
  4931     * 'inline:' scheme works like 'attachment:', but tries to
  4932       inline the content of the attachment into the page;
  4933       currently knows about "*.py" sources and colorizes them
  4934     * support for Java applet "TWikiDrawPlugin" via
  4935       drawing:<drawingname> URL scheme (you need to activate
  4936       the AttachFile action if you want drawings)
  4937     * numeric entities (&#nnnnn;) are now optionally NOT escaped,
  4938       which allows you to insert more characters into a Latin-1
  4939       page, especially the Euro symbol
  4940     * navi_bar is now a list of page names which should be linked
  4941       on every page
  4942     * test.cgi is now rolled into moin.cgi, and can be called
  4943       by adding "?test" to the wiki base URL. Also, as a security
  4944       feature, the server's environment is only shown for requests
  4945       local to the web server.
  4946 
  4947 Unfinished features:
  4948     * user defined forms
  4949     * XML export of all data in the wiki
  4950 
  4951 Documentation:
  4952     * extended the online help ("Help*" pages)
  4953     * German help pages (thanks to Thomas Waldmann)
  4954 
  4955 Bugfixes:
  4956     * #425857: python Parser bug on the second call
  4957     * #424917: Caching control
  4958     * #465499: Two HTTPS problems
  4959     * #491155: FrontPage hardcoded
  4960     * Handling of inbound UTF-8 encoded URIs (only with Python >= 2.0)
  4961     * Fix for subtle changes in "re" of Python 2.2
  4962     * User-provided URLs are now never URL-escaped, which allows appending
  4963       #anchors and using %20 for spaces in InterWiki links
  4964 
  4965 -----------------------------------------------------------------------------
  4966 Version 0.10 (2001-10-28, Revision 1.134)
  4967 
  4968 This version is still Python 1.5.2 compatible, but it's not extensively
  4969 tested for that version and some parts of the system might not work
  4970 there, especially seldom used macros and actions. Bug reports welcome!
  4971 
  4972 New features:
  4973     * "#deprecated" processing instruction
  4974     * config entry "SecurityPolicy" to allow for customized permissions
  4975       (see "security.py" for more)
  4976     * added distutils support
  4977     * though not extensively tested, the standalone server now does POST
  4978       requests, i.e. you can save pages; there are still problems with
  4979       persistent global variables! It only works for Python >= 2.0.
  4980     * "bang_meta" config variable and "!NotWikiWord" markup
  4981     * "url_mappings" config variable to dynamically change URL prefixes
  4982       (especially useful in intranets, when whole trees of externally
  4983       hosted documents move around)
  4984     * setting "mail_smarthost" and "mail_from" activates mailing
  4985       features (sending login data on the UserPreferences page)
  4986     * very useful for intranet developer wikis, a means to view pydoc
  4987       documentation, formatted via a XSLT stylesheet, for details see
  4988       http://purl.net/wiki/python/TeudViewer?module=MoinMoin.macro.TeudView
  4989       or MoinMoin/macro/TeudView.py
  4990     * "LocalSiteMap" action by Steve Howell <showell@zipcon.com>
  4991     * Added FOLDOC to intermap.txt
  4992 
  4993 Bugfixes:
  4994     * Full config defaults, import MoinMoin now works w/o moin_config.py
  4995     * Better control over permissions with config.umask
  4996     * Bugfix for a UNIX time billenium bug (affecting RecentChanges
  4997       sorting and page diffs)
  4998     * data paths with directory names containing dots caused problems
  4999

  5001 Version 0.9 (2001-05-07)
  5002 
  5003 New features:
  5004     * XML page input (pages that start with "<?xml") and XSLT formatting
  5005     * Page caching, for now limited to XSLT processing (where it's
  5006       absolutely needed); new code & API to add the "RefreshCache" link
  5007     * Selection of common date/time formats in UserPreferences
  5008     * New action "titleindex" to support wiki introspection (MetaWiki);
  5009       see the new links below the index bar in "TitleIndex"
  5010     * UserPreferences: editable CSS URL for personal styles
  5011     * PageInfo: the editor's name or IP is shown for each change
  5012     * WantedPages: a new macro that lists links to non-existent pages
  5013     * OrphanedPages: a new macro that lists pages no other page links to
  5014     * Extensions to the FullSearch macro (see HelpOnMacros)
  5015     * Python syntax highlighting
  5016     * "DeletePage" action (has to be activated, see MoinMoinFaq)
  5017     * "Remove trailing whitespace from each line" option in the editor
  5018     * I18N (currently German and Swedish)
  5019     * Config option "url_schemas" to extend the supported URL types

  5022 Bugfixes:

  5025     * New config parameter "html_head_queries": send additional header
  5026       for all pages EXCEPT the "normal" view; main usage is to have
  5027       only the normal pages indexed by a spider, not the edit, print,
  5028       etc. views (which cause multiple hits on the same information)
  5029     * Store the modification time of the page file in the editlog, not
  5030       the current time when the log entry is created

  5140 
  5141 New features:
  5142     * When saving, a datestamp saved in the form and that of the file are
