Drupal Modules

Overview

Drupal 6 has a long-standing bug in the block module (as of 5/10/2011). This bug affects block caching mechanisms. The bug manifests itself if you have block caching enabled.

Once a module's blocks have been registered with the system (in the {blocks} table), the block's caching mode settings are never updated in the {blocks} table, regardless of subsequent cache flushes or other system updates. This is only a problem for modules that change the 'cache' info returned from hook_block op='list' calls.

Uninstalling and re-installing the module won't fix the problem due to another Drupal 6 bug.

This problem impacts any module that changes the caching mode returned in hook_block('info') operation. In particular, the views module allows you to edit a block view's caching mode after creation, but, due to this bug, the changes will never take effect, leading to much head-scratching.

The fix

There are a few core patches available (see Issue 235673, above), but they may not apply cleanly to your Drupal 6 installation; I don't patch core unless there's a critical need. In this case, the patches failed to apply on the sites that needed the fix. So I created a simple custom module that implements the guts of the most recent patch.

Note: You can download the module in the Attachments section, below. Leave a comment if you find this module useful, or, if you have questions about it.

Drupal 7 has been released. As expected, it appears to be a significant improvement over Drupal 6 and earlier versions. Congratulations to the core team for this major milestone!

But what about essential contributed modules? The #D7CX (Drupal 7 Contrib Experience) effort was intended to ensure that Drupal 7 did not suffer the same fate as the Drupal 6 release -- many modules were not available for Drupal 6 well after its release (the problem continues to this day).

In order to make the biggest possible impact, we need as many modules as possible to have full Drupal 7 releases on the day when core Drupal 7 is released. Our failure to accomplish this for Drupal 6 was devastating. So, let's turn our attention toward D7CX - Drupal 7 Contrib Experience.

We are collecting pledges from maintainers to support the D7CX effort. A pledge consists of writing a statement like below at the top of your project page on drupal.org. [...]

My experience shows that availability of stable contributed modules is crucial to adoption: I delayed migration from Drupal 5 to Drupal 6 on my existing web sites for well over a year, and when rolling out a new web site that would have been perfectly suited to Drupal, I chose to roll out with Drupal 5 due to the availability of fully released and tested contributed modules.

As a former Drupal contrib module developer, I understand the difficulties related to upgrading modules for each major version's new release. I'm just now getting back into Drupal module development, and with the Drupal 7 release now a reality, I wanted to know how successful the #D7CX pledge effor twas. So I started digging around, looking for contributed modules with a full

As of today, 1/9/2011, here are some of my favorite Drupal contributed modules that do not have a full Drupal 7 release available on the project homepage. (Most have alpha, beta, or -dev versions available, and they may be perfectly usable on a production site, though I'd suggest a thorough test first.)

• Administration Menu
• Adsense
• Adsense Injector
• Amazon
• Bad Behavior
• Devel
• Google Analytics
• Image API
• LoginToboggan
• Mollom
• Panels
• PathAuto
• Token
• Views
• XML Sitemaps

So, unless I misunderstand what "a full Drupal 7 release" means, it looks like we have a ways to go. I will see if there is any way I can assist in the effort...

How about you? What modules do you rely on, and are they available for Drupal 7 as a full release? If not, what can you do to help make the Drupal 7 version available soon?

Drupal 5 and later versions provide an animation when you expand or collapse a collapsible form fieldset.

While this is a nifty effect, it can be annoying to some users, and it can slow you down when viewing a web page over a Remote Desktop session in Windows (I use Remote Desktop a lot at home, and the expand/collapse animation can take seconds to complete depending on network speed–it all adds up).
