  file HISTORY.txt.


  CacheFu 1.1.1

    - Release manager: Ricardo Newbery, ric@digitalmarbles.com
      Compatible with: Plone 3.0 and Plone 2.5.3

    - Added an VHM 'inside-out' example to the custom rewritePurgeUrls
      script.  [newbery]

    - Fixed the migration from pre-1.1 cache policies.  [newbery]

    - After reinstall we now move the new policies to the top of
      the list.  [newbery]

    - For most use cases, Accept-Language in Vary is unnecessarily 
      conservative. Even in many multi-lingual sites, Accept-Language 
      is not common. So it's no longer the default.  [newbery]

    - Cachefu is now disabled if filesystem version doesn't match installed 
      version. We also update the schemas upon reinstall. The combination of
      both of these should catch most problems with mutating schemas.  [newbery]

    - Implemented feature enhancement #9: stale-while-revalidate / 
      stale-if-error  [newbery]

    - We no longer magically override the headerset settings based on the 
      proxy cache configuration selection. We might have a reverse proxy 
      cache that is not purgeable so now we always respect the policy settings. 
      This is better done explicitly anyway.  [newbery]

    - The id widget for the cachetool is now always hidden. Changing 
      this id would break things badly.  [newbery]

    - Fixed several svn external properties broken because of svn 
      reorganization. [erral]

    - Reorganized several imports and schema definitions to improve 
      code readablity. [newbery]

    - Fixed the reinstall sequence to route around potential cachepolicy
      id collisions.  [newbery]

    - Removed two policy sets from the default install. Squid-without-vary
      because latest squid now properly supports purge with vary. 
      Default-cache-policy-v2 because tests don't show any improvement 
      over the old default policy and because of potential (but unconfirmed) 
      problems with the no-cache rule.  [newbery]

    - Added kss registry to resource cache rule  [newbery]

    - Added a cache rule for RSS feeds [newbery]

    - Added 'b_start' to etag for templates cache rule. 
      Fixes http://plone.org/products/cachefu/issues/97  [newbery]

    - Removed cachetool.unindexObject() from Install.py since we've already 
      disabled the indexing and it was contributing to 
      http://plone.org/products/cachefu/issues/92  [newbery]

    - Eliminated a possible source for zodb write conflicts in high write 
      scenarios. Hopefully fixes http://plone.org/products/cachefu/issues/105  
      [newbery]

    - Fixed traceback_supplement for Plone 3.0  [rossp]

    - After Plone 3.0.1, something changed in Archetypes trunk that 
      breaks a couple of our templates.  Added an explicit definition 
      for the "allow_tabbing" variable in these templates to fix it.  
      [newbery]

    - Fixed references to 'CacheFu' in install instructions where it 
      should be 'CacheSetup'  [erikrose]

    - Products.PageTemplates.TALES is obsolete. We now import 
      zope.tales.tales instead  [wichert]

    - With plone 3 trunk and zope 2.10.4 the (un)registerUtility keywords 
      are 'component' and 'provided', in IFiveSiteManager (Five 1.5.5) 
      they are the old way (utility, interface) but IFiveSiteManager does 
      not seem to be used here so this is changed [svincic]

    - Added keyword arguments when calling (un)registerUtility, because
      the order of the arguments is the other way round in the IFiveSiteManager
      interface (at least with Five 1.4.4)  [witsch]

    - Was previously doing a naive check for Plone 3 style site managers
      which would fail on Plone 2.5 if the portal had been converted to 
      a local site with Five 1.4.  Fixed to test for five.localsitemanager.
      [rocky]

    - Added method getEnabled to cache_tool to partly fix 
      http://plone.org/products/cachefu/issues/96  [maurits]

    - Cleaned up the icon. Properly transparent with no white border, 
      slightly bigger, a little color, and a bit of 3D embellishment 
      [newbery]

    - Added a documentFirstHeading class and removed the icon from the main tab
      to match the other control panels -- don't want to stand out do we?  
      [newbery]

    - Added BaseCacheRule to types_not_searched. 
      Fixes http://plone.org/products/cachefu/issues/113  [newbery]

    - Some tests were updated; some new tests added; some test refactoring.
      Added policy http cache manager cache rule implementation tests. 
      Testing schemas is deprecated. Added tests for class and skeleton
      tests for methods. Removed unused imports [hvelarde]

    - Moved BaseContent class inheritance to BaseCacheRule to simplify code
      in final classes. BaseCacheRule class is initialized now to avoid
      potential security issues. Updated test suite to reflect these changes.
      [hvelarde]

    - Added plone_tool marker to cache_tool [hvelarde]

    - Brought back cachingPoliciesDummy.html. This was accidently removed
      in the last release. It's a cosmetic thing; caching_policy_manager
      needs this for it's ZMI view. [newbery]

    - Proxy config changes:

      1) Cleaned up and updated the proxy configs.  Moved 'config' directory
         to the more descriptive 'cachefu-proxy-configs'.  Cleaned up the 
         readme instructions. Renamed the makeconfig configuration to makeconfig.cfg,
         to clarify it's purpose. Added new configs for Squid and Varnish proxy 
         cache setups. Added some example configs for an Apache-only proxy cache 
         setup. Eventually, we're probably going to deprecate this and recommend
         buildouts for the proxy configs. [newbery]

      2) Bug fixes:  Corrected the log file path for squid log files, but 
         kept them commented. Removed references to unexistent scripts in
         proxy config deploy script [erral]

      3) Bug fix:  Moved ';' to the tal:define in xxxxxxx.  Was just behind it [redcor]

      4) Bug fixes:  Fixed print statement in makeconfig. Removed unnecessary
         squid_direct condition. Removed "direct" directive and adjusted 
         makeconfig to match. [newbery]

      5) Bug fixes:  In apache configs, uncommented the "RewriteEngine On" line.
         Added an 'all' acl to the Squid configs, since Squid appears to 
         need this in some situations. Fixed the proxy deploy script to not
         try to chmod files that do not exist. Fixed some bugs in makeconfig.
         [wichert]

    - Bundled the current tagged CMFSquidTool which includes the latest changes:

      1) Many Squid configurations ignore query strings, but not all.
         Query strings are not retained in purge urls. [alecm]

      2) Fixed getUrlsToPurge when the object has no REQUEST. [maurits, reinout]

      3) Fixed a blocking Queue.put call that never raised Queue.Full
         and so was never caught [rossp]

      4) Squid (at least version 2.6.STABLE14) returns 404's for PURGE requests
         using HTTP 1.1 when an "Accept-Encoding: identity" header is included
         in the request. Squid now doesn't generate this header. [dunny]
