Is it possible to purge all pages in mediawiki? I've tried emptying the obejctcache table to no avail. I don't particularly want to hit each page with ?action=purge appended. Version 1.23.3

    @jww the simple fact the question is over a year old, not closed and has upvotes and answers with votes would suggest to you that a) it's a suitable question which is useful to the community or b) is in dire need of being closed. And besides, this question is about development of a mediawiki site which involved programming. – user3791372 Nov 21 '15 at 08:15

You can either

  1. Use the maintainance script PurgeList.php like this: php purgeList.php --purge --all, for MW > 1.21, and php purgeList.php --all-namespaces for MW > 1.34. Really old MW versions do not have the --all option, so you will need a list of pages.

  2. Use the API: API:Purge, and feed it with a list of all pages (that you can get from API:Allpages)

  3. Invalidate all caches by setting $wgCacheEpoch to the current time in LocalSettings.php, e.g. $wgCacheEpoch = 20140901104232;.

  4. Set $wgInvalidateCacheOnLocalSettingsChange (since MW 1.17) to achieve pretty much the same thing. Only do this if your wiki has low to moderate traffic.

  5. Not sure if this is a good idea, but if you have access to the wiki's database you should also be able to achieve the same effect by truncating the table objectcache.

Invalidate all caches for all sites with this simple command:

touch /etc/mediawiki/LocalSettings.php

because in the touch LocalSettings.php file there is this part:

# When you make changes to this configuration file, this will make
# sure that cached pages are cleared.
$wgCacheEpoch = max( $wgCacheEpoch, gmdate( 'YmdHis', @filemtime( __FILE__ ) ) );

__FILE__ is the LocalSettings.php file itself, so if the filetime is now, all cache older than the file will be purged.

    This is the better answer. – snowguy Mar 02 '15 at 04:05

    Note that this is not part of `LocalSettings.php` since MW 1.17. Instead, there is a setting called `$wgInvalidateCacheOnLocalSettingsChange` that will achieve pretty much the same. This method is great for smaller wikis, but [not recommended](https://www.mediawiki.org/wiki/Manual:$wgInvalidateCacheOnLocalSettingsChange) for high traffic wikis. – leo Oct 27 '15 at 08:55

Use purgePage.php as the equivalent to action=purge
