Description
I upgraded from 1.3 to 1.4 today. Then, every time I flush caches on Drupal, the old content remains in Memcached. For example, if I flush cache on the site, all those .js and .css files path are still the old ones in memcached, so anonymous users will see the broken site.
#1
I'm unable to duplicate. How do you have memcache configured?
#2
I configured using the codes below.
<?php$conf = array(
// The path to wherever memcache.inc is. The easiest is to simply point it
// to the copy in your module's directory.
'cache_inc' => './sites/all/modules/memcache/memcache.inc',
// or
// 'cache_inc' => './sites/all/modules/memcache/memcache.db.inc',
);
?>
for installation, I followed http://www.lullabot.com/articles/how_install_memcache_debian_etch

I've the same problem
my conf:
$conf['cache_inc'] = './sites/all/modules/authcache/memcache.inc';
$conf['memcache_servers'] = array( 'localhost:11210' => 'default',
'localhost:11211' => 'block',
'localhost:11212' => 'content',
'localhost:11213' => 'filter',
'localhost:11214' => 'menu',
'localhost:11215' => 'page',
'localhost:11216' => 'views',
'localhost:11217' => 'views_data');
$conf['memcache_bins'] = array('cache' => 'default',
'cache_block' => 'block',
'cache_content' => 'content',
'cache_filter' => 'filter',
'cache_menu' => 'menu',
'cache_page' => 'page',
'cache_views' => 'views',
'cache_views_data' => 'views_data');
$conf['memcache_key_prefix'] = 'test2';

What versions of memcache and the pecl extension are you using.
There's an issue with using the latest (1.4.3) version of memcache. See http://pecl.php.net/bugs/bug.php?id=16927
#5
I have the same problem.
Using:
Memcache API module 6.x-1.4
Memcache PECL extension 2.2.5
Memcached 1.2.6, 1.2.8, 1.4.2, or 1.4.4
I have the same issue with all of the above versions of memcached. This is happening on a server with the most basic memcache config, as well as a config with multiple bins and session caching configured.
Please let me know if there's anything else I can do to help you get to the bottom of this.
edit: OK, this appears to be fixed in the latest dev snapshot. Maybe time for a new release?
edit: I was mistaken. Neither the 6.x-1.4 release nor the latest dev snapshot appear to be doing deletes properly.
#6
I also have the problem with Memcached 1.3.3.
#7
I uninstalled the latest Memcache API module and installed Memcache API 6.x-1.3. Now my cache is being flushed properly. Seems to work fine with memcached 1.2.6, 1.3.3, and 1.4.4. Seems like there's some kind of a bug in Memcache API 6.x-1.4 and above.
edit: With Memcache API 6.x-1.3 the cache seems to get invalidated every about every second request, so I really have no idea whether or not deletes are actually working.
#8
OK, I got a little further on this. I had "Minimum cache lifetime" set in the page caching settings. If this is set, dmemcache_flush() will never be called. I don't know if this is the desired behavior, but this isn't the way Drupal normally works. When using standard Drupal caching even if I have a "Minimum cache lifetime" set, if I hit the "Clear cached data" button, the cache gets cleared. When I hit the "Clear cached data" button I am doing so because I want the cache cleared right now. I don't see why you wouldn't want it to work that way.
Anyway, to others who experience this issue, make sure your "Minimum cache lifetime" is set to "None".
