Problem wfShellExec - MediaWiki-l

7 Oct 2013

I'm not sure this is a problem in the server or in MediaWiki.

I have an extension which calls a bash script with wfShellExec. The
bash file consists essentially of

touch $1.A
latex $1
dvipng $1
touch $1.B

The touch'es are just to see if the bash file is run. And indeed it's.
However, neither .dvi nor .log files are created (which are the result
of running latex). However, when running the script from the
command line everything is ok.

This extension is based on WikiTeX.php, and the lines calling the
script are:

$cmd =  wfEscapeShellArg( $wfTexConvert, $tempName, $dpi, "$storedir/$hash"
);
wfProfileIn( "TeX-shellexec" );
$convtext = trim( wfShellExec( $cmd ) );
wfProfileOut( "TeX-shellexec" );

Any ideas about what's wrong? Perhaps some permission not set?

By the way, TeX is TeXLive2012, installed separately, and the site is
www.wikilengua.org .
