I did a comparison between my wiki install (version 1.23.1 upgraded in two steps to 1.23.3) and the latest version of MediaWiki (version 1.23.3).

The 'images' directory in the copy of my wiki (cpwiki) is missing as I ran 'diff' on another machine (i.e. not the server hosting the website) and didn't want to copy those files (13 GB).

What caught my eye is "Files cpwiki/includes/GlobalFunctions.php and mediawiki-1.23.3/includes/GlobalFunctions.php differ"

# diff ./cpwiki/includes/GlobalFunctions.php ./mediawiki-1.23.3/includes/GlobalFunctions.php ----------------------------- 2923c2923 < $status = proc_get_status( $proc ); ---

	$status = proc_get_status( $proc );

	if ( !$status['running'] ) {

-----------------------------

"GlobalFunctions.php" ( http://www.mediawiki.org/wiki/Manual:GlobalFunctions.php ) seems to be important... and the change makes me wonder whether a bug is lurking somewhere in this.

I don't know why I have the difference... but I tend to think it shouldn't be there-- if the patches were applied properly.

I looked at the last two patch files ( mediawiki-1.23.3.patch.gz , mediawiki-1.23.2.patch.gz ). The latest patch ( mediawiki-1.23.3.patch.gz ) has changes to 'GlobalFunctions.php'.

I did the 1.23.3 patch on August 29th. Temporally, this doesn't align with when the problems started; my problems started a couple of days before then. In any case, I don't understand how this could explain the problems I have... but it is something that looks funny.

Thanks, Michael
