`git svn dcommit` segfault

[Tim Stoakes <tim@stoakes.net>]

Hi all,

I've been using git-svn on this repository for a while now, and all has
been well. However, this time it segfaulted in the middle of a dcommit
(4 commits into about 15). I've had to sanitise the file names, as this
is a commercial project.

$ git svn dcommit
...
        M       <snip_file>
Committed r164
        M       <snip_file>
r164 = 72ff1bf62f9b3828efb93d1b2681d154e960b8a2 (git-svn)
No changes between current HEAD and refs/remotes/git-svn

Segmentation fault

It was git-svn that segfaulted I assume, not any git commands it calls,
because I see this in my syslog:
git-svn[27348]: segfault at 18 rip 2b9bc87e17e3 rsp 7fffe6ed04f0 error 4


And now I have a dirty checkout:
$ git status
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#       modified:   <snip_file>
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#           <snip_file>
#           <snip_file>
#           <snip_file>
#           <snip_file>
#           <snip_file>
#           <snip_file>
#           <snip_file>
no changes added to commit (use "git add" and/or "git commit -a")

It *looks* as if this dirty state is the sum total of the outstanding
commits, so I don't think I've lost my work, only my history of that
work.


`git log` shows up to r164, the last one before the segfault.


I can't run dcommit again, because my checkout is now dirty:
$ git svn dcommit
Cannot dcommit with a dirty index.  Commit your changes first, or stash
them with `git stash'.


fsck shows some dangling entries:

I'd re-run it to get a core file, but I don't know how to get myself
back into the initial state.

I'm using 'git version 1.5.4.3', and 'svn, version 1.4.6 (r28521)' on
the client. The server is 'svn, version 1.3.1 (r19032)', I think.

I'm a bit stuck! Any help is much appreciated. Would any other
information be useful?

Thanks
Tim
