Bug 98360 – www-apps/trac-0.8.4 - error with trac/subversion python hooks

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Fraser Ruffell 2005-07-08 08:53:49 UTC]

I installed www-apps/trac-0.8.4 on my AMD64 gentoo box, however when I try to
run 'trac-admin' I recieve:

Traceback (most recent call last):
  File "/usr/bin/trac-admin", line 34, in ?
    from trac import sync
  File "/usr/lib64/python2.3/site-packages/trac/sync.py", line 22, in ?
    from svn import core, fs, delta, repos
ImportError: No module named svn

The python hooks installed by the subversion package are located in
/usr/lib64/svn-python, which by default is not in python's sys.path.

On my x86 32-bit box the subversion hooks are located in
/usr/lib/python2.3/site-packages/svn which is contained within python's
sys.path, so everything works fine there.

To work around this, I created a file called "svn.pth" located in
/usr/lib64/python2.3/site-packages which contains a single line:

/usr/lib64/svn-python/

Alternativley, a symbolic link could be made, or the subversion modules could be
installed to the python site package directory as is done on x86.

Reproducible: Always
Steps to Reproduce:
1. emerge trac subversion python
2. issue the trac 'trac-admin' command
3.

Actual Results:  
Traceback (most recent call last):
  File "/usr/bin/trac-admin", line 34, in ?
    from trac import sync
  File "/usr/lib64/python2.3/site-packages/trac/sync.py", line 22, in ?
    from svn import core, fs, delta, repos
ImportError: No module named svn

Expected Results:  
Executed the program without error.

Python folks, please advise.

[Comment 2 Yogesh 2005-07-28 07:01:39 UTC]

Shortcut might be:
ln -s /usr/lib64/svn-python/svn /usr/lib64/python2.3/site-packages/svn
ln -s /usr/lib64/svn-python/libsvn /usr/lib64/python2.3/site-packages/libsvn

Fraser, which profile are you using? please post your emerge info

[Comment 4 John Bertagnolli 2005-09-28 06:31:23 UTC]

I masked trac and two of it's required packages (silvercity and clearsilver) to get it installed. I have trac 
installed cleanly and it is running without a problem. It looks like whatever requirement in python that was 
causing a problem is now fixed. I would recommend unmasking these packages for amd64 and closing 
this bug.

can't reproduce it with trac-0.9.2, assuming the new version fixed that issue.
please reopen if you still suffer from this bug
