STATUS_ACCESS_VIOLATION with git svn

Question

I'm trying to migrate our code from an SVN repo (TortoiseSVN 1.9.3 64 bits) with about 1 GB data on it, to a TFS 2015 with a Git repo. I have Git on my computer (2.9.0.1) and when I try this command line:

git svn clone https://server/directory/trunk

It creates the .git folder, but then I have a perl.exe.stackdump file with the following problem

Exception: STATUS_ACCESS_VIOLATION at rip=00000000000

I have read that Git uses the .subversion/servers files to authenticate, so I guess this isn't the problem? I work exclusively on Windows.

Answer 1

The cause is most likely due to the size of a large commit. I’ve seen similar issues before when fetching, cloning or rebasing while using Cygwin git when the change set is so large that Git and/or Perl run out of memory (it’s not fun when a colleague commits large video files). Closing all other memory-intensive processes helps a lot. FWIW, I also found that I had less problems after upgrading Cygwin from 32-bit to 64-bit.

This seems to be a well-known bug in Msys Git and according to comments on the bug report, you should

try calling successive git svn fetch calls to continue

Use of the 64-bit version of Git for Windows is also recommended. Good luck with it.
