Observed on translatewiki.net. Steps to reproduce unknown. [01-Jan-2013 09:16:51 UTC] PHP Notice: LocalFile::lock: Transaction already in progress (from WikiPage::doDeleteArticleReal), performing implicit commit! [Called from DatabaseBase::begin in /www/translatewiki.net/w/includes/db/Database.php at line 3002] in /www/translatewiki.net/w/includes/debug/Debug.php on line 283 [01-Jan-2013 09:16:51 UTC] PHP Notice: FileDeleteForm::doDelete: Explicit commit of implicit transaction. Something may be out of sync! [Called from DatabaseBase::commit in /www/translatewiki.net/w/includes/db/Database.php at line 3051] in /www/translatewiki.net/w/includes/debug/Debug.php on line 283
Bug reports with very similar messages: Bug 43575, bug 41462, bug 40877 (which is fixed by https://gerrit.wikimedia.org/r/#/c/27274/ ).
There are many different variations of this database problem, unlikely to be related to uploads only.
It would be trivial to find the issue if translatewiki could install xdebug, so we would have stack traces...
Do we really need xdebug to get stack traces? Can't we use wfGetBacktrace() or something like that if we needed one? Also these notices are fairly easy to reproduce. I get one every time I do action=purge without exception
I stil get this (with or without Wikibase) when running deleteBatch.php (even if my batch is just a single page): PHP Notice: WikiPage::doDeleteArticleReal: Transaction already in progress (from DeleteBatch::execute), performing implicit commit!
