AssertionError when selecting browse source

Reported by: nico-trackhack-git@… Owned by: Herbert Valerio Riedel
Priority: normal Component: GitPlugin
Severity: blocker Keywords:
Cc: Trac Release: 0.11


I installed trac & trac-git from debian lenny: 0.11 of trac:

ii trac 0.11-3 Enhanced wiki and issue tracking system for ii trac-git 0.0.20080710-1 Git version control backend for Trac

I did GIT_DIR=trac/g1 git init and git push trac master:refs/heads/master to populate the git-repo. trac options:

[git] cached_repository = false git_bin = /usr/bin/git persistent_cache = false shortrev_len = 7

[trac] repository_dir = /home/nicosc/trac/g1/ repository_type = git

nicosc@ikdesk1:~/trac/g1$ git --version git version

I get this error:

return self.rev_cache[0]

File "/usr/lib/python2.5/site-packages/gitplugin/", line 316, in get_rev_cache

assert all(e is not None for e in self.rev_cache)


Any idea what I did wrong?

I get something comparable whenever it tries to resolve a rev:

  File "/usr/lib/python2.6/site-packages/trac/wiki/", line 802, in handle_match
    return external_handler(self, match, fullmatch)
  File "build/bdist.linux-i686/egg/tracext/git/", line 122, in <lambda>
    self._format_sha_link(fmt, 'changeset', sha, sha))
  File "build/bdist.linux-i686/egg/tracext/git/", line 79, in _format_sha_link
    changeset = self.env.get_repository().get_changeset(sha)
  File "build/bdist.linux-i686/egg/tracext/git/", line 223, in get_changeset
    return GitChangeset(self.git, rev)
  File "build/bdist.linux-i686/egg/tracext/git/", line 390, in __init__
    (msg, props) = git.read_commit(sha)

Using Trac

As a result, nothing from GIT is available anymore.

Note: This is after having patched GitPlugin to fix this issue: #4227

comment:3 Changed 10 years ago by lhunath

Uhm, I take that back. After cleaning up the patch I submitted for #4227 my issue went away.

In case the patch difference is somehow useful (if this issue is even related to what I was struggling with) I will commit the cleaned up patch (which does fix #4227) as a separate file.

Have you tried creating some entries in git repo ? If it is null sometimes it gives this assertion.

Resolution: duplicate

Looks like a duplicate of #4139
