[Mediawiki-l] Fixing database after lost images

[John Pye]

Hi all,

I am having some trouble with our wiki at
http://ascendwiki.cheme.cmu.edu after a recent problem where a hard
drive problem caused us to lose the images in our wiki. We managed to
retrieve the database and I have reinstalled Mediawiki now (version
1.9.3) and some images I have put back into place in the wiki images
folder (/var/www/wiki/images/X/XX/whatever.png), but it is becoming
clear that all is not as it should be.

The first problem is that some of the images that I have replaced (from
files from other sources pre-wiki) in the above folders do appear in the
wiki, but do not appear to be thumbnailing correctly -- the image show
with rough-looking resizing, not the usual nice smooth job that I take
it is done by imagemagick.

The second problem is that I can't make uploading work any more. I have
set everything up in LocalSettings.php and the folder permissions look
right. I have set the $wgHashedUploadDirectory also. The funny thing is
that when I use the upload page, the image appears to upload (the HTTP
request takes a few moments) but then it fails silently: I am returned
to the upload page again, with no error message, and no message shows up
in the Apache error log either.

I tried to run management/rebuildImages using php5 CLI but it fails with
a message about failing to connect to the database with user = root and
no password. I couldn't see where to set the password (I tried modifying
php.ini but that wasn't it). So I can't see how to run this script, either.

Any suggestions for all this would be much appreciated. I'm sure it must
be something fairly simple I've failed to do.

Cheers
JP

PS I notice that some upload issues have been addressed in the new 1.10
release. Could that be related?
