mediawiki-extensions - package... strongly suspect bug, wonder about adv. of deb packages...
Hi John,
Thanks. ( http://lists.debian.org/debian-user/2009/02/msg01426.html )
I did get one module working (Cite.php).
Above said, I have the impression that there is an incompatibility, between the
'mediawiki-extensions' package and 'mediawiki' in the stable branch. I cannot
confirm this... as I cannot find the upstream version information for the
'mediawiki-extensions (1.4)' package ( http://packages.debian.org/source/lenny/mediawiki-extensions ).
However, I note that 'sid' and 'squeeze (testing)' use the '1:1.13.3' branch of mediawiki. I'm quite certain the error I'm getting (see below) arises from a packaging problem in Debian, i.e. Debian package 'mediawiki' (1:1.12.0-2lenny2) is not compatible with 'mediawiki-extensions' (1.4), as mediawiki-extensions (1.4) appears to be derived from extension in the 1.13 branch of mediawiki.
I know that Mediawiki ( http://www.mediawiki.org/wiki/MediaWiki ) specifies that the version of
the extensions has to match the program, e.g. Mediawiki version 1.12 has to use the extensions
for version 1.12. I note that there has been a previous bug, which appears to be related to
this very issue -- based on the changelog http://packages.debian.org/changelogs/pool/main/m/mediawiki-extensions/mediawiki-extensions_1.4/changelog
-- see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=473785 .
I'm having problems with the ParserFunction extension (see error message below).
My set-up --
Versions:
mediawiki: 1:1.12.0-2lenny2
mediawiki-extensions: 1.4
-----
As for a fix...
I think that the 'mediawiki-extensions' package should be clearly 'mediawiki' version dependent, i.e.
there ought to be a package 'mediawiki-extensions 1.12-1' (for mediawiki version 1.12) and a package 'mediawiki 1.13-1' (for mediawiki version 1.13).
-----
In any case, what are the advantages of using Debian's packages for mediawiki?
-I've had the impression it would ease upgrading... but I'm uncertain about that.
-I've had the impression that I'd get security updates quickly...
Currently, I'm seeing some disadvantages...
-more limited documentation (see http://lists.debian.org/debian-user/2009/02/msg01271.html http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516693 )
-possible additional bugs (see above)
Thanks,
Michael
