Created attachment 15344 [details] LocalSettings file When I enable RevisionDelete, select a revision in the history, Select "Change Visibility", select a "restriction option", and finally click "Apply to selected revision", I get a blank page and a PHP Fatal error in the logs. I am enabling RevisionDelete with: $wgGroupPermissions['sysop']['deleterevision'] = true; $wgGroupPermissions['sysop']['deletelogentry'] = true; Syslog error: PHP Fatal error: Cannot inherit previously-inherited or override constant READ_LATEST from interface IDBAccessObject in /www/wiki/includes/Revision.php on line 26, referer: http://******/index.php?title=Test&action=revisiondelete&ids%5B17%5D=1 URL: http://*****/index.php?title=Special:RevisionDelete&action=submit
Thanks for reporting this! Which PHP version and which database backend and version are this?
I believe the relevant packages are: php-5.3.28-1.5.amzn1.x86_64 php-mysql-5.3.28-1.5.amzn1.x86_64 php-intl-5.3.28-1.5.amzn1.x86_64 php-xml-5.3.28-1.5.amzn1.x86_64 php-pecl-apc-3.1.15-0.3.svn329913.10.amzn1.x86_64 mysql55-server-5.5.37-1.46.amzn1.x86_64
This looks like an issue with APC. Try disabling it to see if it works.
Kenneth: Can you answer comment 3, please?
I tried changing my config to this: [--- ## Shared memory settings #$wgMainCacheType = CACHE_ACCEL; #$wgMemCachedServers = array(); # RevisionDelete - http://www.mediawiki.org/wiki/Manual:RevisionDelete $wgGroupPermissions['sysop']['deleterevision'] = true; $wgGroupPermissions['sysop']['deletelogentry'] = true; ---] But I still get this error: [--- [Wed Jun 18 19:20:18 2014] [error] [client XXX.XXX.XXX] PHP Fatal error: Cannot inherit previously-inherited or override constant READ_LATEST from interface IDBAccessObject in /www/wiki/includes/Revision.php on line 26, referer: http://XXX/index.php?title=Test&action=revisiondelete&ids%5B207%5D=1 ---]
APC is still enabled, even if MediaWiki isn't trying to use it. Set apc.enabled to 0 in your php.ini to actually disable it.
disabling apc in /etc/php.ini appeared to work. "Revision visibility successfully updated." So that would confirm an issue with APC and the RevisionDelete extension. What could be done to fix the issue?
It looks like you're hitting https://bugs.php.net/bug.php?id=59101 The solution is to upgrade APC. There's no bug in MediaWiki.
Ok, thank you.
