Description Tom London 2004-08-03 01:33:33 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040625

Description of problem:
cups appears to open /usr/share/printconf/util/backend.pyo for writing.

This fails if /usr/share/.... is not writable, or if running with
strict SELinux policy.

Perhaps making /usr/share/printconf/util/backend.pyo a symlink
(say, to /etc/cups/backend.pyo)......

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot system with USB printer (say, HP 950PSC), and /usr/share
read-only, or with SELinux strict/enforcing

Fixing component.
Comment 2 Tim Waugh 2004-08-03 04:16:13 EDT
Apps that ship Python code should also ship the .pyo/.pyc bits IMHO --
but apparently this is not trivial to do correctly.  CC'ing Python
maintainer for further input.

As far as SELinux goes (and I think this is what prompted this bug
report) these should be dontaudit, and I thought they were at one point.
Comment 3 Tom London 2004-08-03 10:23:57 EDT
dontaudit would remove the avc's, but the write of the file would fail.

That would be OK if the the .pyo is never used, but then ....

Comment 4 Tim Waugh 2004-08-03 10:31:47 EDT
The .pyo file is just to speed up loading of the Python module -- it
is for optimization, which in this case is lost in the noise of having
to load the foomatic database later on.

Waiting for redhat-rpm-config to turn on the Python pre-compilation.

Comment 7 Elliot Lee 2005-03-21 23:43:21 EST
Tim - if you'll tell me what changes to make, I can do that, or feel free to
just check in the necessary changes yourself.
Comment 8 Tim Waugh 2005-03-22 06:36:48 EST
/usr/lib/rpm/brp-python-bytecompile needs to get run in
Comment 9 Elliot Lee 2005-04-06 23:18:09 EDT
Enabled in redhat-rpm-config CVS, it'll wind up in the dist sooner
Comment 10 Tim Waugh 2005-04-18 09:55:39 EDT
Please build this.  Thanks.
