Purging all pages in mediawiki

Question

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

Answer 1

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.
