Patch to fix #1639

comment:1 Changed 7 years ago by adam

The above patch fixes this problem. The issue appears to be that Trac occasionally looks for a commit that doesn't exist in the git repository. An example here is the WikiFormatting page, which will cause this error on a default install of 0.10.

The patch returns bogus committer and author information, which causes Trac to not blow up.

This may or may not be the right thing to do; I'm not at all familiar with Trac's internals. It does work, though.

...actually, that patch is for the other git plugin.

comment:3 in reply to: ↑ 2 Changed 7 years ago by anonymous

  • Component changed from TracGitPlugin to GitPlugin
  • Owner changed from sjain to hvr

Replying to anonymous:

...actually, that patch is for the other git plugin.

Updated to reflect the GitPlugin, instead of TracGitPlugin. The patch still fixes the bug, though.

(In [3174]) GitPlugin:

  • speeded up get_history and rev_older_than
  • raise NoSuchChangeset exception if invalid changeset revision is requested (addresses #1639)
