Change Log

RELEASE-0.0.4

  • Initial Magento Connect release

RELEASE-0.0.5

  • Add new VCL backend for Magento admin with longer timeout values

RELEASE-0.0.6

  • Make backend timeouts and grace period configurable
  • Initial Magento Enterprise Edition compatible release on Magento Connect
  • Improve cache hit-rate in some cases

RELEASE-0.1.0

  • Hole-punching support via ESI
  • Crawler support for cache warming
  • Most issues with Varnish socket communication will display flash errors instead of throwing exceptions
  • Many/most configuration options were changed or renamed

RELEASE-0.1.1

  • Fixed EE ESI template and layout install location
  • Fix missing files in previous Magento Connect package

RELEASE-0.1.2

  • Disable ESI injection if request does not come through Varnish to prevent broken output for SSL-enabled sites

RELEASE-0.1.3

  • Fix ESI block rendering to be more accurate. This fixes the issue where some blocks didn't render exactly right (missing links in the header block)

RELEASE-0.1.4

  • Added ESI block flushing on customer login/logout
  • Fixed syntax error under PHP 5.2
  • Added syntax check to build script
  • Made footer block global ESI cached by default
  • Removed Varnish Management admin page
    • VCL is now saved and applied on Varnish Options and Caching Options config saving
    • Cache clearing is now integrated into Cache Management page like other Magento cache types
    • Cache clearing by URL and content-type have been removed since they were not very useful in light of automatic cache clearing

RELEASE-0.1.5

  • Fix VCL application and saving when the Magento compiler is enabled
  • Remove defunct debug option config dependancies
  • Added right.poll block to default ESI cache policy
  • Fix occasional "ESI processing not enabled" message (double ESI-include)
  • Fix Varnish Pages refresh not flushing Varnish cache

RELEASE-0.1.6

  • Add support for identifing crawlers by User-Agent in addition to IP address, see the new Crawler User Agents setting (matches Googlebot, siege, ab, and MageSpeedTest.com by default)
  • Fix stale Login/Logout links
  • Add documentation for SSL Support

RELEASE-0.2.0

  • Added AJAX injection for very short lived and/or frequently changed blocks (like the flash messages). This should resolve the issue with flash messages not displaying or displaying sporadically. To enable for other blocks, change the setEsiOptions method in the turpentine_esi.xml layout file to setAjaxOptions. Note that AJAX injected blocks are not cached at all
  • Added TTL extension for cache hits. Cached object's TTL will be extended by a small amount on cache hits to keep frequently used cache objects from expiring (unless the cache is flushed), allowing for lower TTL values to keep the cache from filling.
  • Prevented ESI injected blocks from being cached via Magento's block html caching while still allowing full block output to be cached. This is an improvement on the fix in RELEASE-0.1.5 for double ESI-includes
  • Fixed Magento using the ESI getBlock URL as the previously visited URL for visitor sessions
  • Fixed ESI injected blocks using the ESI getBlock URL as the current URL when rendering
  • Reduced size of generated VCL to reduce chance of hitting CLI buffer limit

RELEASE-0.2.1

  • Changed the syntax for dummy blocks and registry keys in the setAjaxOptions and setEsiOptions layout methods, see the wiki for the new syntax
  • Improved serialization of registry items in ESI/AJAX blocks
  • Fixed AJAX requests always being over HTTPS even if the main page was requested over HTTP
  • Changed the dummy URL to "/checkout/cart" instead of "/"
  • Fixed AJAX injection for messages block, which didn't use the standard layout method for block definitions. This also includes a new option to "Fix Flash Messages" which allows for disabling the new behavior for compatiblity with other AJAX extensions
  • Fixed POST request caching, which sometimes caused POST requests to fail the first time, and then succeed (bug introduced in RELEASE-0.2.0)
  • Fixed CE 1.6 + EE 1.11 incompatibility introduced in RELEASE-0.2.0

RELEASE-0.3.0

The new site crawler functionality in this release adds a new User-Agent to the default Crawler User Agents setting: "Nexcessnet_Turpentine/.*" It is strongly recommended to manually add this new user agent string to the Crawler User Agents setting after upgrading as Magento won't automatically update the config setting with the new default value if the config has been saved before. This does not apply to new installs.

  • Added built-in crawler for automatically warming the cache. Also automatically warms pages that are flushed on save (product/category/CMS pages)
  • Removed hard-coded "messages" block AJAX options, the ESI/AJAX options for the "messages" block can now be configured in the ESI layout file like any other block
  • Made ESI client-cache ban (clear) events configurable. See the new "ESI Client Cache Purge Events" option
  • Enabling the Normalize User-Agent setting now also differentiates between desktop and mobile browsers, for caching different output for desktop and mobile browsers
  • Fixed messages block not correctly updating the layout if the layout cache was enabled
  • AJAX loaded blocks now (quickly) fade in instead of popping in
  • Enabled continuous-integration builds for PHP 5.2, 5.3, and 5.4 through Travis-CI. This is only relevant to developers and has no effect on users of the extension

RELEASE-0.3.1

  • Fixed generated VCL to work with multi-store/multi-site setups with different URL paths

RELEASE-0.3.2

  • Fixed Turpentine not correctly detecting and disabling ESI/AJAX on requests with HTTP Authorization
  • Fixed some requests being passed through Varnish instead of piped resulting in incorrect handling of response output
  • Removed cached object TTL extension (added in RELEASE-0.2.0) due to issues with cached object contention at high load
  • Improved warm-cache.sh script to handle different platforms better and take advantage of multiple processors/cores
  • Added advanced session validation. Varnish will now respect the Magento settings for validating the User-Agent, X-Forwarded-For, and Via headers, and the remote IP address with respect to sessions (under System > Configuration > General > Web > Session Validation Settings).

RELEASE-0.4.0

There are changes to the ESI layout syntax in this release, any customizations that have been done to the ESI layout will need to be updated

  • Improved serialization of ESI/AJAX data in URLs. ESI/AJAX URLs should now be 50-75% as long as they previously were
  • Fixed rare cases of invalid characters in ESI/AJAX URLs, which would cause the block to not load or display an error message
  • Unified AJAX and ESI code paths. ESI and AJAX includes no longer use duplicated code which will make it easier to add other other inclusion methods in the future and reduces the potential for bugs
  • Selecting between AJAX and ESI inclusion is now done with the method parameter to setEsiOptions, setAjaxOptions is no longer supported
  • Added ability to cache AJAX requests
  • The old cacheType parameter for setEsiOptions in the layout has been split into two new options: scope and access
    • scope = global: the cached object valid for the entire site
    • scope = page: the cached object is specific to a single page
    • access = public: the cached object is valid for any visitor
    • access = private: the cached object is valid for a single visitor's session
  • ESI block default TTL options have been removed. The new default for public ESI blocks is the same as the Varnish page TTL and private blocks use the session cookie lifetime as the TTL
  • Turpentine will now detect if there is a difference between how a block should be loaded vs how it is requested (ex. manually changing the method parameter for a AJAX block to ESI). If ESI debugging is turned off an error (403) will be returned
  • Client-side caching will now be used for static assets, in addition to Varnish's regular caching (via the Cache-Control header)
  • Improved page rendering performance. Pages that include ESI blocks will now render significantly faster (up to 50% in testing), dependant on how many ESI block includes were on the page
  • Fixed Turpentine ESI request entries in the Magento visitor log. This should result in a small speed-up for AJAX requests particularly as most of the time token for the request was spent doing the logging
  • Added custom VCL inclusion. Custom logic can be added to the VCL Turpentine generates by putting it in app/code/community/Nexcessnet/Turpentine/misc/custom_include.vcl. If this file is found, Turpentine will automatically include it. Note that it is not Varnish version-specific like the other templates, users will need to make sure the VCL code used is compatible with the version of Varnish that they use

RELEASE-0.5.0

There are changes to the ESI layout syntax (again) in this release, any customizations that have been done to the ESI layout or added for custom blocks will need to be updated and moved to the local.xml file. Additionally, the Varnish cache will need to be fully flushed or cached pages that reference previously cached ESI blocks will not load those blocks

  • Added support for event-based partial ESI cache flushing. ESI blocks will now only be flushed on the events specified for them in the layout rather than all of a client's ESI blocks being flushed on any event that triggered a flush
  • Removed the purge_events option as it was no longer needed with the new partial ESI flushing support
  • Removed the need for initial request pass through, Varnish will now generate a session token for new visitors and serve them pages from the cache on their first visit
  • Fixed CMS pages not being automatically flushed on update
  • Fixed piped requests in Varnish not having headers handled appropriately
  • Added ability to whitelist IP addresses for debug info from Varnish, even if Varnish debugging is disabled via Magento's developer IP setting
  • Added flushing on a product page, product review list, and individual review view on review saving (such as changing from 'Pending' to 'Approved')
  • Combined the Varnish and ESI debug options
  • Made the logging done by the extension consistent, all messages logged by Turpentine will be prefixed with TURPENTINE:
  • Added HMAC signing to the encrypted ESI data to prevent possible tampering with the ESI data in the request
  • The turpentine_esi_custom.xml file that was previously suggested to be used for custom ESI policies has been removed in favor of Magento's built-in facility for this (local.xml). Any ESI policies defined in turpentine_esi_custom.xml should be moved the local.xml file in the theme's layout directory to prevent issues with the order of defining blocks and setting ESI policies on them.

RELEASE-0.5.1

This is the first release of Turpentine marked "stable" in Magento Connect

  • Fix PHP error when Block Logging is turned on
  • Saving a child product of a configurable or grouped product will now also cause the parent product(s) to be flushed. This makes saving consistent with the out-of-stock flushing behaviour
  • Varnish will now properly distinguish between HTTP and HTTPS responses. This should fix warnings in some browsers about mixing secure and insecure content when using Varnish+Turpentine behind an SSL proxy

RELEASE-0.5.2

  • Added profiling calls for more debugging and performance-profiling options
  • Fixed layout XML caching logic to prevent writing to the cache on every page load, this should result in a small performance improvement on Varnish cache misses
  • Fixed multiple frontend cookies being generated when Magento was installed in the root of a domain (/)
  • Added support for translating the SID URL param into the frontend cookie for sharing sessions across different domains
  • Added utility script to dump Varnish's active VCL (util/dump-active-vcl.sh) for debugging
  • Improve ESI URL redirect interception, Turpentine should now prefer to redirect to the referring URL instead of defaulting to /checkout/cart/ all the time
  • Re-enabled visitor logging for ESI/AJAX requests, this fixes product comparison for non-logged-in visitors

RELEASE-0.5.3

  • Added runtime model/helper/block rewriting. This negates the need to comment out the core/messages block rewrite to really disable the flash messages fix when using Turpentine in combination with certain other extensions
  • Add run-time detection of Varnish cli_buffer param to allow for longer VCLs after increasing the limit at Varnish start up
  • Added the new Fix Product List Toolbar option (under Varnish Options > General) to prevent caching of the products-per-page and product sorting options in the product list toolbar. Note that this option defaults to Disabled
  • Added the store and currency cookies to the request hash. This allows Varnish to differentiate between multiple stores with the same base URL and fixes currency handling.
  • Added a new option to disable the automatic application of the new VCL when making changes to the Varnish Options or Caching Options config sections
  • The Flush Catalog Images Cache and Flush JavaScript/CSS Cache no longer also flush the corresponding URLs in Varnish. This helps prevent broken images and script links after using those buttons.
  • Fixed Varnish ESI parsing failures that some users were experienced. This should prevent the "ESI processing not enabled" seen on some blocks
  • Removed the default ESI policy on the checkout.cart block as it was causing the shipping and tax quoting to not update correctly. It will be re-added in a future release once the quote issue is resolved
  • Added a X-Turpentine-Block header to ESI/AJAX responses containing the name of the block rendered
  • Disabled caching of the product comparison popup in the default ESI policy. This does not affect the product comparison block, only the popup window showing the actual comparison

RELEASE-0.5.4

  • Fixed the Varnish-generated frontend cookie occasionally being set with the wrong path when Magento was located in a subdirectory instead of the root of the site
  • The built-in crawler should no longer try to crawl products that are not visible in the frontend
  • Missing blocks caused by layout changes between different handles should be handled more gracefully by Turpentine now
  • Parent products will also be banned when a child product goes out of stock or is saved
  • Fixed CMS URL generation for the built-in crawler
  • Fixed product stock change check to actually work
  • Improved the dummy request mock up. It should have all expected fields populated now and changes to it will not affect the global state or original request
  • Added a Magento shell script (util/varnishadm.php) that can be used like the real varnishadm command for users who aren't able to use real varnishadm command
  • Fixed duplicate flash messages experienced in some cases (thanks to @craigcarnell)
  • Made the custom_include.vcl file's location configurable, see the new Custom VCL File Location option
  • Added template parsing to the custom include VCL file, {{variable}} replacement will now also work in this file
  • Added a toggle-able Varnish Bypass to Cache Management page for bypassing the cache (including ESI) for a single admin session (thanks to @alexandre-jardin)
  • Varnish will now strip the Google-related parameters from the request to increase cache hit-rate

RELEASE-0.5.5

  • Made VCL templates slightly shorter to help with running into the inline VCL character limit
  • The warm-cache.sh script now respects the PROC environment variable for the number of processes to use while warming the cache
  • [#253] Fixed VCL to correctly identify Chrome on OS X
  • [#281] Fixed unintentional flushing of full cache in some cases (thanks @jeroenvermeulen)
  • [#301] Fixed IE caching AJAX ESI includes (thanks @nickbock)
  • [#320] AJAX ESI should be compatible with themes that use jQuery instead of Prototype (thanks @steverice)
  • [#334] Bad URIs that cause the dummy request creation to throw an exception will now log the bad URI and hide the exception when debugging is disabled (thanks @ajardin)
  • [#337] Improve layout handle searching for ESI blocks in some cases (thanks @sanbornm)
  • [#356] Fix ESI blocks not rendering child blocks (thanks @magedev)
  • Changed Varnish-generated session ID format for compatibility with the SFC_Kount extension
  • Failures during advanced registry loading in ESI requests should be handled more gracefully

RELEASE-0.6.0

This release requires a small addition to Varnish's configuration when used with Magento CE 1.8+ or EE 1.13+, see these instructions

  • [#362] Fixed ESI detection for message block (thanks @eth8505)
  • [#380] Fixed ESI cache flushes not firing in some cases (thanks @gabrielsomoza)
  • [#391] Added Magento Composer Installer support (thanks @ajardin)
  • [#405] Fixed disabling Varnish bypass (thanks @ajardin)
  • [#438] Implemented ban lurker-friendly bans (thanks @jeroenvermeulen)
  • [#443] Fixed caching of static assets when the Add Store Code to Urls option is enabled (thanks @jeroenvermeulen)
  • [#345] Fixed compatibility with Magento CE 1.8 and EE 1.13
