git svn clone died of signal 11 on OSX

Question

I'm trying to migrate a project from svn to git. I was using the osx svn package, but I also tried installing with homebrew. I keep getting this same error.

git svn clone http://myserver/myrepo
error: git-svn died of signal 11

Version information:

git --version
git version 2.2.1

svn --version
svn, version 1.7.17 (r1591372)
   compiled Sep 18 2014, 13:06:44

I'm running Yosemite.

First thing to do, is to debug git command to see on which component it fails by adding GIT_TRACE=1, e.g.

$ GIT_TRACE=1 git svn clone https://example.com/svn/foo/ foo
21:12:40.239238 git.c:557               trace: exec: 'git-svn' 'clone' 'https://example.com/svn/foo/ foo/' 'foo'
21:12:40.240158 run-command.c:347       trace: run_command: 'git-svn' 'clone' 'https://example.com/svn/foo/ foo/' 'foo'
error: git-svn died of signal 11

and re-run the last command in the corrupted repository which shows that the crash happened in git-svn binary.

In order to do that, you need to identify where you've git-svn binary, e.g.

$ which -a git-svn
$ locate git-svn | grep git-svn$
/Applications/GitHub.app/Contents/Resources/git/libexec/git-core/git-svn
/Applications/SourceTree.app/Contents/Resources/git_local/libexec/git-core/git-svn
/Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-svn
/Library/Developer/CommandLineTools/usr/libexec/git-core/git-svn
/usr/local/libexec/git-core/git-svn
/usr/local/Cellar/git/1.8.4.1/libexec/git-core/git-svn
/usr/local/Cellar/git/2.4.0/libexec/git-core/git-svn

If you've multiple git-svn binaries, to find out which one is used, run:

sudo fs_usage -f exec | grep git

in another terminal before running the failing git command again.

Once you've identified which git-svn you run, run it directly like:

/usr/local/libexec/git-core/git-svn ...
/usr/local/Cellar/git/2.4.0/libexec/git-core/git-svn 

and it's most likely that it'll crash no matter which parameter you will specify, otherwise specify as shown from trace output.

Sometimes it maybe a symbolic link, so check where it points to, e.g.:

$ stat /usr/local/libexec/git-core/git-svn
  File: ‘/usr/local/libexec/git-core/git-svn’ -> ‘/Applications/GitHub.app/Contents/Resources/git/libexec/git-core/git-svn’

If that's the case, change the symbolic link to the one which is not crashing, e.g.

$ ln -vfs /Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-svn /usr/local/libexec/git-core/git-svn 
‘/usr/local/libexec/git-core/git-svn’ -> ‘/Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-svn’

Alternatively identify to which package your git-svn belongs to and upgrade accordingly, e.g.

• /Applications/Xcode.app -> upgrade Xcode,
• /Applications/GitHub.app -> upgrade GitHub app

• /usr/local/Cellar/git -> upgrade git via Homebrew, e.g.

  brew upgrade git
  

  If Homebrew will complain about the file conflicts, then run:

  brew link --overwrite git
  

If you still crashing after upgrade, use different version (as mentioned above) which doesn't crash, e.g.

/Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-svn clone https://example.com/svn/foo/ foo

If that works for you, add to your PATH and later on use git-svn command instead, or add an alias, e.g.:

alias git-svn='/Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-svn'

If you got any missing dependencies for the new git-svn, install Git::SVN by running:

sudo cpan install Git::SVN

Debugging

If above won't help, you may debug it further more. Here are some suggestions to run in separate terminal, then in run the failing command:

sudo dtruss -fn git

or:

sudo dtruss -fn git-svn

To identify which git-svn is called, you may try:

• sudo /usr/bin/newproc.d
• sudo fs_usage -f exec | grep git
