What would the minumum parameter for drupal_bootstrap needed for an ajax call to a drupal url which points to a callback that only has a return statement in it

Posted by mitchelljj on February 7, 2011 at 9:25am

Any reason why having a javascript timer fire every 2.5 second for an ajax
request to my own callback(listed below) that all it does is return the

contents of 2 _session variables would take up so much resources?

 function refreshcarttimer() {
     print($_SESSION['num_items'] . ',' .  $_SESSION['uc_price']);
     return;
 }

 /**
  * Implementation of hook_menu().
  */

 function product_type_menu() {
   $items = array();

Discussion of Step-by-step: Setting up Project Mercury

Posted by mgifford on February 9, 2011 at 4:41pm

I'm just experimenting with Varnish & Drupal 7 now and am getting stuck here:

http://groups.drupal.org/pantheon/mercurywiki#config-apache-varnish

I want to set this up in a environment on debian that uses both D6 & D7 sites. I'm not looking to use pressflow, but understand that this shouldn't be required with the changes in D7.

3a) The whole /etc/apache2/ports.conf

Hi Guys,

Clear cached node pages at node creation

Posted by elkin_taharon on February 11, 2011 at 1:12pm

Hi,

Maybe this is a silly question, but i just realized that the varnish module is clearing all my varnish cached objects instead just the ones affected at node creation ( the front page if it promoted, the node's taxonomy, etc), is this a normal behavior ?

There is a way for remove just the affected pages ?

Batch API without a browser

Posted by mikeytown2 on February 11, 2011 at 9:07pm

I already use code that does batch processing in the background (no browser window used) in any hosting environment. The question is would something like this be useful to the Drupal community; if yes how can one override Drupal's batch operations to use my processor.

Kernel killing varnish process due to out-of-memory issue

Posted by ISPTraderChris on February 14, 2011 at 4:11pm

We're having an issue on our Mercury installation where Varnish will unexpectedly and require a manual restart -- this is obviously a pretty big deal given that our site effectively goes down until it is remedied. A look at the syslog reveals the following:

Feb 14 02:17:06 ip-xx-xx-xx-xx kernel: Out of Memory: Kill process 4493 (vshd) score 356911 and children.
Feb 14 02:17:06 ip-xx-xx-xx-xx kernel: Out of memory: Killed process 4493 nishd).

Imagecache image sprite

Posted by mikeytown2 on February 14, 2011 at 8:59pm

Nutty idea of mine. Have an imagecache image sprite module. But you say you can't use a sprite in an img tag. That is incorrect because we currently do that. Proof: http://bellevue.komonews.com/business-directory Do an inspect element on the deals image. Cool eh? (location hint pic)

APC Settings / Performance - Full Cache and Fragmentation

Posted by Lloyd on February 16, 2011 at 4:59pm

Just installed APC on a server that hosts just a few sites. I also enabled the Cache Router module on one site, and each site has Boost running. Originally I installed APC 3.1.6 but apparently there is an issue with that version and it doesn't load Drupal modules into Cache. So everything looked good, but I upgraded to 3.1.7 and now there are many more files being loaded into cache (good) but I'm filling up the cache and getting fragmentation as well.

I've attached a printout of apc.php but here are my current settings.

apc.cache_by_default 1
apc.canonicalize 1

Everything going the wrong way

Posted by cookie235 on February 17, 2011 at 8:43pm

Hi everybody,

I am working on a Drupal site that needs to be quite fast. I must mention it is using Domain Access, and TAC. I've been trying to setup Memcache and Varnish in an effort to improve the general performance of the site, but things have been going downhill rather than uphill. I am using Pressflow, though it was originally an Acquia install (I just overwrote the files). Here are a few numbers :

Anonymous     : regular cache  : 41  #/s (cache normal in preferences)
