Called to undefined function dmemcache_object in memcache_admin.module [#1156354]

Hello,

We upgraded to version 1.9 this morning in our Continuous Integration System at work and there is small problem when running the updb in drush.

Here is the log:

The following updates are pending:

A simple solution could be to include that line:

module_load_include('inc', 'memcache', 'dmemcache');

On the top the of memcache_admin.module but I don't know if it's better to put it there OR to put it in the needed function (memcache_admin_stats_type()) on line 411.

Anyway, I provide the 2 patches, can you tell me what's the best thing to do in that case ?

My latest patches failed to apply in Jenkins, probably because of the a and b added in front of the files.

I reroll the files without those front directory (see issue http://drupal.org/node/1110430).

First patch fixes that error when you're installing, but doesn't fix it when you go to /admin/reports/memcache

Second patch fixes both. Not sure if it needs to be loaded all the time like that, though... ? Didn't look into it too deeply... thanks for the patch though.

Hello m.stenta,

I'll work again on it on Monday, by the time, keep sending me feedback, I'll provide a new patch if needed!
I wonder if it's not a dependency problem from memcache_admin.

I'll check it out on Monday, first hours, because I don't have the time this week end to touch a computer :(

See you!

OK, well I figured out what was causing the problem on my machine: http://drupal.org/node/1147672

Pol: if you have the APC PECL module installed, try uninstalling it:

sudo pecl uninstall apc

(and also delete the "extension=apc.so" from php.ini (or from /etc/php5/conf.d/apc.ini if that's where it is).

That solved the problem for me. If it solves it for you too, then this issue can be closed as a duplicate of http://drupal.org/node/1147672.

I get this error without APC. So I don't think it's a duplicate.

Hello guys,

I made further tests and I cannot reproduce the error once the first patch in #2 is applied.

Can you provide more feedback about it ?

Thanks !

Comment #10

scroogie commented 16 May 2011 at 11:22

I can confirm that the patch in #2 worked for me as well on memcache 1.9.

I can also confirm that the first patch in #2 worked for me. I was getting this error when trying to run "clear all caches"

Catch, does this really need additional review? It's just a module_load_include() for using the dmemcache_object(), which is called in the update.

@scroogie I marked it as needs review because I keep forgetting there's a patch here.

Additionally you should never use module_load_include() unless you can be certain you're in full bootstrap, although the 2.1 version of the patch looks OK from that, so will probably commit that next time I'm looking at this.

Patch in #2 allowed me to install and use the module, marking as such.

Hello @Jim,

Which version of the patch ? the 2.1 or the 2.2 ?

Comment #17

@Pol: erm, both... !

I figured belt and braces is best... Obviously for an actual patch one or other is better.

Thanks!

Marking 'to be ported' since similar may be needed in the 7.x branch.

I'm getting a similar error using 6.x-1.x:

Fatal error: Call to undefined function dmemcache_stats() in /home/api/domains/api.freestylesystems.co.uk/public_html/sites/all/modules/memcache/memcache_admin/memcache_admin.module on line 230

Seems like this needs another module_load_include.

psynaptic's patch in #19 works for me on 6.x-1.x-dev (1 July 2011). It seems like a goofy thing to have been omitted.

That function is in dmemcache.inc, including that file fixes the problem

function memcache_admin_stats_types($bin) {

I found this happened if the settings.php didn't include the appropriate memcache configuration. This is just for reference for anyone else experiencing this bug.

zuernbernhard commented 8 January 2014 at 08:12

Exactly ! These lines in the config (sites/default/settings.php) made my day:

$conf['cache_backends'][] = 'sites/all/modules/contrib/memcache/memcache.inc';
$conf['cache_default_class'] = 'MemCacheDrupal';
$conf['cache_class_cache_form'] = 'DrupalDatabaseCache';

Thank you !

Comment #32

deanflory commented 25 May 2015 at 12:29

Here's what I put into settings.php based on the latest README instructions:

/**
 * Memcached (server), memcache (server), memcache module (Drupal)
 */
$conf['cache_backends'][] = 'sites/all/modules/memcache/memcache.inc';
$conf['cache_default_class'] = 'MemCacheDrupal';
$conf['cache_class_cache_form'] = 'DrupalDatabaseCache';
$conf['page_cache_without_database'] = TRUE;
$conf['page_cache_invoke_hooks'] = FALSE

Pretty clear documentation here:
https://www.drupal.org/node/1131468

I ended up getting a WSOD from that, so I removed the last two lines which brought my site back:

$conf['page_cache_without_database'] = TRUE;
$conf['page_cache_invoke_hooks'] = FALSE

Called to undefined function dmemcache_object in memcache_admin.module
