The S-Files: Acquia Drupal Stack installer Got packet bigger than max_allowed_packet bytes

Tech Support Case Studies

The S-Files are a taste of the support that you get with a subscription to Acquia Support. Our support team helps you solve technical problems relating to your Drupal sites.

The Acquia Drupal Stack installer is a major productivity booster for getting up and running in the development of your Drupal site. Sometimes, though, Drupal modules like to cache huge data packets in the database. This results in an error in your browser that says this:

Got packet bigger than ‘max_allowed_packet’ bytes

This is an indication that the data being sent between Drupal and the database is large, and exceeds the default setting.

Fortunately the fix for this is easy. In the application installation directory of the stack installer you'll find the following directory and file:

Applications/acquia-drupal on my Mac

Edit the my.ini file with whatever text editor you like, and add these lines to the end:

#Max packets
max_allowed_packet = 128M

Now stop and start the Acquia Drupal Stack using the Acquia Drupal Control Panel, and the new setting will come into effect. This should solve your max_allowed_packet problem!

10 usability guidelines

Smashing magazine recently published an article titled "10 useful usability findings & guidelines." There's a lot of good information here for both core committers and themers.

Of the findings, I found myself disagreeing with only one - "Most users do not scroll." In my testing, I've found the opposite - so long as false bottoms are not present. To avoid false bottoms, make sure content or design elements run past the bottom of your browser. See illustration below.

Gardens Usability Testing - Rd 1 filled

I wanted to thank everyone who signed up for Drupal Gardens usability testing. I received a lot of requests - unfortunatly I won't be able to accept all of them.

Usability testing focuses on a subset of tasks and requires only 6-10 users to identify problems. Any number greater than 10 merely reveals the same problems over and over again. Thankfully, D7 and Drupal Gardens are both feature rich, so there will be many more tests in the very near future.

Thanks so much,
Jeff Noyes

Apache Solr Excitement at Drupalcon

As of the final Drupalcon Paris code sprint, http://groups.drupal.org was upgraded to Drupal 6, and its site search has also started running on Apache Solr. Since last summer we have used a scrubbed groups.drupal.org database dump which we updated to Drupal 6.x as a test set for Apache Solr Search Integration functionality and screen shots. Having it live on the groups site is great because we've been able to see for months the kind of improved search results that are possible, but frustratingly unable until now to access them in real life.

The groups.drupal.org upgrade was only one of the exciting developments, lively BoFs, or informative presentations around the integration of Apache Solr with Drupal last week. I enjoyed hearing Mike O'Conner's talk about his efforts to integrate Solr search with Ubercart, and several teams discussed their plans to use Apache Solr for existing sites or upcoming projects.

I received a lot of requests (thank you), but only a few provided email addresses. Trying to aggregate a list and communicate with everyone proved to be a chore. If you're interested in becoming a usability tester, please sign up here:

Drupal.org steps up helping localized Drupal installs grow

I just came back from Drupalcon Paris this week. It was an action packed conference with lots discussed and many things done to further Drupal's reach. In my case, I've submitted sessions to teach people to write modules the right way, theme Drupal in minutes and translate Drupal interfaces to multiple languages. Thankfully only this last submission was accepted, but that was about a new service on drupal.org which first needed to launch. Way to get people to advance services on Drupal.org!

Drupal Gardens open for usability testing

As I'm writing this entry, my colleague Barry Jaspan is over my shoulder getting frustrated while attempting to adjust his desk at our new office space. He's using a cleverly designed screwdriver designed to bend at 90 degrees and manipulate screws in hard to reach areas. While the idea of an adjustable, bendable screwdriver sounds like a good idea, based on observing Barry and a few others, I'm certain the inventor failed to observe people trying to use it.

Drupal Gardens preview screencast

Last week at DrupalCon Paris, we demonstrated a pre-alpha version of Drupal Gardens, which will allow non-technical users to go from design to online with a powerful Drupal 7 social publishing website in a matter of hours instead of days. The Acquia engineering team has been hard at work implementing Gardens on top of Drupal 7 and we wanted to show a small taste of things to come.

Stacking up Drupal

Why the Acquia Drupal Stack is now the Drupal development stack of choice. Drupal On-ramp - Personal experiences at Drupal events in recent months and reports from friends and colleagues indicate that the Acquia Drupal Stack Installer is really changing the installation experience for new users. This incredibly fast, painless on-ramp experience - it lets you get right into "Drupalling" without fighting with ports, permissions, or database connections - is winning over new users at Drupal Camps around the world.
