Enscript not working after change to mod_python

Reported by: jc@… Owned by: Christopher Lenz
Priority: normal Milestone:
Component: web frontend/mod_python Version: 0.10.3
Severity: normal Keywords:
Cc: Branch:
Release Notes:
API Changes:


I changed from fgci to mod_python (because then I can bind the Trac to www.myhost.com/, with fcgi I need an script alias e.g.www.myhost.com/trac) But then I noticed that trac cannot span any external programs e.g. htmldoc for the pdf plugin, or enscript for beautify.

Here a log snippet from an enscript call:

2006-12-19 06:34:43,560 Trac[__init__] WARNING: HTML preview using <trac.mimevie
w.enscript.EnscriptRenderer object at 0xa93aa88c> failed ([Errno 2] No such file
 or directory: '/tmp/tmpuzLyax')
Traceback (most recent call last):

    outfd = file(outfile, 'r')
IOError: [Errno 2] No such file or directory: '/tmp/tmpuzLyax'

The Apache 2.2 is running on a debian (and with fcgi everything works fine!) with trac 0.10 (Debian Etch)

PS: Am unsure about the component… so first assigned to mod_python?! because it works if not using mod_python.

Probably a SELinux issue, see #2231, Noah's comment. Please follow-up there.

Based on the follow-up on #2231 SELinux is not installed, so this isn't a duplicate.

Note that mod_python is not required to host Trac at myhost.com/, you can do this with fcgi like:

ScriptAlias / /usr/lib/cgi-bin/trac.fcgi

Oh that was new to me, in the past a "ScriptAlias / …" to a cgi was not allowed/working. But anyway, that would lead me to another problem, that I then cannot reach some folders e.g. media/photos/svn which I setup as follows

<LocationMatch /(photoCache|icons)>
   SetHandler None
   Options +Indexes

As far as I know you cannot say "noscript" ;) for some locations. (but I'm maybe wrong)

So currently I have the Trac installed under /cms and do a rewrite from / to /cms if the url is not inside (photos|cms|svn|…).

Ok ugly workaround but works perfect for me. And it doesn't solve the system call problem inside the mod_python.

Replying to mgood:

Based on the follow-up on #2231 SELinux is not installed, so this isn't a duplicate.

Well, #2231 is not necessarily about SELinux (that was just an hypothesis there), but rather about "Trac do not locate Enscript temp file", which is exactly the subject here. Moreover, comment:ticket:2231:5 already contains a stack trace exactly similar to the one reported here.

Duplicate of #2231 (for the reasons mentioned above).
