Release Notes

State Final release
License GPL
Release Manager Ricardo Newbery

CacheFu is a collection of products which aggregate and simplify various caching settings, speeding up Plone sites using a combination of memory, proxy, and browser caching.  CacheFu can be used by itself or with Squid, Varnish, and/or Apache.  Configuration files can be generated for Squid, Varnish, Squid-behind-Apache, Varnish-behind-Apache, and Apache cache proxy (if you are using a non-caching Apache by itself or just Zope-only, no extra configuration files are needed).

CacheFu is currently shipped as a separate add-on to Plone as we expect more releases in the near future to add additional features and flexibility.  CacheFu 1.1.2 has been tested on Plone 3.0 and Plone 2.5+.  For earlier Plone versions, try CacheFu 1.0.3 instead.

 

New Features in CacheFu 1.1.2

  • Improved proxy cache configs for Squid and Varnish.
  • Some bug fixes.

 

New Features in CacheFu 1.1.1

  • New improved proxy cache configs for Squid, Varnish, and Apache (yes, Apache can be used as a proxy cache server -- although it doesn't support PURGE requests).  Look in the 'cachefu-proxy-configs' folder for more information.
  • Added an VirtualHostMonster 'inside-out' example to the custom rewritePurgeUrls script.  The rewritePurgeUrls script is found in the 'cache_setup' skins folder.
  • Added support for 'stale-while-revalidate' and 'stale-if-error'.  See http://www.mnot.net/blog/2007/12/12/stale
  • Added kss registry to resource cache rule.
  • Added a cache rule for RSS feeds.
  • Lots of bug fixes.

 

New Features in CacheFu 1.1

  • An "off" switch.  Previously, you had to uninstall in order to turn off caching. Now you can turn it off without losing your configuration.
  • Multiple cache policies. A cache policy is a container for cache rules and header-sets so you can now have multiple sets of rules and headers for different occasions or site development purposes.
  • Caching of Zope 3 views.
  • Customizable purge urls.
  • Improved Last-Modified dates.
  • Simplified Squid configs.
  • Varnish configs.

 

New CacheFu Manual and Web Caching Reference

A new CacheFu Manual and a Web Caching Reference is nearing completion. Stay tuned for an announcement.

 

Installing CacheFu

Installing CacheFu for the first time:

  1. Copy CacheSetup, PageCacheManager, CMFSquidTool, and PolicyHTTPCacheManager into your Products directory.
  2. Restart Zope.
  3. Install the CacheFu product via the Plone "Add/Remove Products" page.
  4. Optional: Configure via the "Cache Configuration Tool"  (see Configuring CacheFu in the Manual).
  5. Optional: Install Squid or Varnish  (see Reverse-Proxy Cache Servers in the Manual).

Upgrading from CacheFu, versions 1.0 - 1.1.1:

  1. Copy CacheSetup, PageCacheManager, CMFSquidTool, and PolicyHTTPCacheManager into your Products directory.
  2. Restart Zope.
  3. Click on the reinstall link next to the CacheSetup product in the Plone "Add/Remove Products" page.
  4. Note: A reinstall keeps your old pre-1.1 configuration in a Cache Policy named "Old Cache Policy".  Any other cache policies with ids that conflict with the new ones will be backed up and relabeled appropriately.
  5. Optional: Configure via the "Cache Configuration Tool"  (see Configuring CacheFu in the CacheFu Manual).
  6. Optional: Install Squid or Varnish  (see Reverse-Proxy Cache Servers in the CacheFu Manual).

  1. Uninstall your existing CacheSetup and CMFSquidTool via the Plone "Add/Remove Products" page.
  2. Continue with the instructions for a "first time" install above.

  • Removed some deprecated tests.  [newbery]

  • Added a default_ttl of zero seconds to the varnish runner.  [newbery]
  • Unauthorized requests now do not trigger a full CacheFu disable. CacheFu is still disabled but no objects are actually removed. A temporary fix for http://plone.org/products/cachefu/issues/134  [newbery]

  • Fixed UnicodeDecodeError in PT_pt_render().  http://plone.org/products/cachefu/issues/126  [newbery]
  • Fixed rewritePurgeUrls.py.  Was referencing the method before its definition.  [newbery]
  • Cleaned up the descriptions of some cache rules. [newbery]
  • Removed RSS from the container rule since we do this in a separate rule now.  [newbery]
  • Fixed typo in getHeaderSetIdForCSSAndJs.py which would throw an error if still using the old cache policy (pre-1.1.1).  [newbery]
