Ah, what a slap-in-the-forhead-moment :) Thank you. On a side note, and in regards to my original secon question about best practice: The '#cache' property in the render array used for the block content is not necessary then, if I understand the mechanics correctly? This would only add a superfluous extra layer of caching? -fredrik > Fra: Randy Fay <randy(a)randyfay.com> > Emne: Re: [development] Block caching in D7 > > Hi Fredrik - > > I think you may have been testing as user 1.

Block caching in D7
by Fredrik Sandve Kilander 11 Dec '10

11 Dec '10

Hello. I am the maintainer of the yr_verdata module, and as I am trying to finish up updating my module for D7, I am having trouble understanding how block caching works. On my development site, I have enabled caching, and in hook_block_info() i have specified caching as per the example at api.drupal.org: $blocks['yr_verdata_block'] = array( 'info' => t('Yr weather forecast for all locations'), 'cache' => DRUPAL_CACHE_PER_ROLE, // I have tried with per page and global as well. ); This does not cache the block. If I set caching in the render array that's passed to $block['content'] in hook_block_view(), the caching works, but there are two things i wonder: 1. Is that the correct way to cache blocks? 2. Using render arrays with the '#cache' element in hook_block_view() works independently of whether or not I 'enable' caching in hook_block_view(). Why is this? What's the best practice for going about this? Source code can be seen at drupalcode.org: http://bit.ly/g586j6 Lines: 185 (hook_block_info), 209 (hook_block_view). Theme function for the block is at 477, which gets its array of stuff from line 327 (the function called there, yr_verdata_generate_forecastbox(), starts at 349). (if you find any other stuff in my code to bash at, feel free :) ) Sincerely, Fredrik Kilander Maintainer of yr_verdata.module

Here is the response from the hoster regarding my claim that the number of tables is a mip (meaningless indicator of performance) MySQL performance on the server is not solely tied to transactions, and this is not a MIP. Our R&D department has shown time, and time again with extensive research on the issue that performance and server stability drastically improves when accounts are under 1000 tables. The affects of the limit are not just seen with the speed/performance of MySQL transactions, but it also has affects on server IO and CPU usage.

+1 to the suggestion for using special_menu_items module. I was going to suggest it last night but wasn't sure if that was your issue or not.

I get the string uncoverted as a result. Might be ckeditor, though it didn't offer filter choice and I disabled it. I'll try adding the field to its black list. The harder part seems to get $footer_msg to appear side by side with $footer Ayen Designs - quality software the first time, every time!

preventing browser cache
by Blake Senftner 10 Dec '10

10 Dec '10

I'm finding that I need to implement a browser cache prevention scheme for dynamic content I am generating. My use case: user supplied info gets converted into XML and loaded by a java applet on the same page. I'm seeing the java applet load cached versions of the data, and I want to prevent this. I don't have the ability to modify the java applet, and it always loads it's XML from the same filename. I'm thinking about using the same technique that I see Drupal use for javascript files, where the src attribute's file url has a fake query string at the end, something like "/misc/drupal.js?5" , where the "?5" is the fake query string. It's my understanding that this prevents browser caching, and ultimately does not trigger a query - so it's a great method for cache prevention of dynamic content. Is my understanding correct? I've not done this before. Is it simply a matter of placing a single random character after the question mark? To anyone that has implemented a scheme such as this: any pitfalls I should be aware?

D7 side effect
by jeff＠ayendesigns.com 09 Dec '10

09 Dec '10

Don't get me wrong, I'm chuffed to mint balls about the D7 effort and the result, for many reasons, not least of which is the amazing talent represented by it. That said, I received a letter today from the hoster stating that my account was a performance problem because it had over 1000 tables. Eight Drupal sites coud be over 1000 tables. I have a hosting account with 'unlimited domains' and up to 25 databases. I use the account both for hosting several live domains, most multi site, as well as a test area that clients can access for testing changes to existing domains. 8 Drupal sites could be over 1000 tables with the typical array of add-on modules, let alone that most of these sites are doing e-commerce. I've let them know that they might want to consider a more meaningful indicator of performance issues than a script that counts tables, since probably none of these sites does more than 100 transactions per day. If they hold firm, I'll blog (and post here) their name.
