We can know what each Debian version contains, and I think we should at least determine this for all the major distributions of MediaWiki so that they are properly supported.

wheezy : http://anonscm.debian.org/viewvc/pkg-mediawiki/mediawiki/branches/wheezy/deb... trunk/jessie: http://anonscm.debian.org/viewvc/pkg-mediawiki/mediawiki/trunk/debian/patche...

I dont see any patch which would cause the API to work differently from the released version for pywikibot. A few might make the server work correctly, where the released version doesnt work, however they are not cases where pywikibot does not currently try to workaround a bug in the server.

trunk has two extra patches allow_pdf.patch fix_variable_use.patch

Debian at least identifies itself. Fedora also packages MediaWiki, and it doesnt appear that it identifies itself, so we cant know whether its API has backports which cause it to operate differently.

However we should fallback on a sensible value, with a UserWarning to indicate that it isnt a fully supported or understood version. i.e. anything starting with 1.19.20 should be treated as 1.19.20 .
