Manual talk:Cache

Why is my edit
Why is my edit to this page still pending after 6 days? The information on the current revision about the required version of eAccelerator is wrong. Are there not enough people to review pending changes? That would be a pretty convincing argument to disable Flagged Revisions. Also, I've got a long history of editing on this wiki. Why aren't my edits automatically approved? --Cneubauer 12:42, 21 April 2011 (UTC)

Don't cache transclusions?
The default behavior seems to be building a cache copy of a requested page by statically including transcluded pages. The end result is that changing the transcluded page does not expire the cache copy of the pages that use it. Those pages therefore become stale. Is there a way to configure MW so that it caches each page without pre-parsing transclusions? This otherwise makes it very difficult to support real-time content (data feeds). Users have to manually purge pages to keep them up to date, or otherwise disable caching completely. 65.87.26.122 19:36, 2 March 2012 (UTC)

Actually I'm not sure if it is transclusion specifically or dynamic content in general (ParserFunctions). 65.87.26.122 19:40, 2 March 2012 (UTC)

Object cache on windows
Has anyone experienced problems with caching on windows? I've tried eaccelerator, apc and xcache on thread safe PHP 5.2.17 and 5.3.13. None of them worked, in all of them MW 1.18 refused to recognize the existence of the cache extension, even though I see it in php info Osishkin (talk) 04:33, 19 July 2012 (UTC)

File Caching
Might be an idea to mention file caching on this page in the introductory paragraph. I just spent a couple of hours trying to enable memory caching on my shared host (bluehost) for a small to medium sized wiki. Then discovered file caching and that solved all the issues right away. Maybe others will be in the same situation. So much simpler, if your host doesn't have memory caching already enabled. I know it is listed under performance if you follow the link, can find it there now but easy to miss when you don't know the option exists. Manual:File_cache

Any difference between purge vs "null edit"?
Hi. w:Help:Dummy edit says that a purge does not update category pages, but a null edit (= pressing an edit button without any change) does. Is it true? Manual:Purge nor w:Wikipedia:Purge don't say any. --Ahora (talk) 06:19, 26 November 2012 (UTC)
 * As far as I tested several times, this statement seems correct. --Ahora (talk) 12:49, 11 December 2012 (UTC)

Using caching breaks password resets?
Hi.

I have APC installed and $wgMainCacheType = CACHE_ACCEL set on a number of wikis (versions 1.17.3 - 1.19.4). I have noticed that password reset is not working in these instances. The user requests a new password and gets emailed a new password, but when they enter it they are informed it is the wrong password. If I restart apache then the new password then works.

If I turn off caching then password resets work as expected. If this is indeed the case, surely this is a major flaw?

 * I can't reproduce this. Check whether it still happens if you set $wgMainCacheType = CACHE_DB;. —Emufarmers(T 13:26, 6 February 2013 (UTC)
