git-svn -- out of memory

Alfred M. Szmidt· Feb 14, 2009, 10:40 UTC · lore

Hi,

when doing a `git svn clone' on a subversion repository that contains a large file (>1GiB), `git svn' dies with the following:

ams@trillian:~$ git svn clone REPO -T trunk -b branches -t tags [...] fatal: Out of memory? mmap failed: Cannot allocate memory hash-object -w --stdin-paths: command returned error: 128

error closing pipe: Bad file descriptor at /usr/local/bin/libexec/git-core//git-svn line 0 error closing pipe: Bad file descriptor at /usr/local/bin/libexec/git-core//git-svn line 0

Doing a `git repack' doesn't help either. Anyone got a clue how to either solve, or work around this?

git version 1.6.1.3

Cheers.

Hi Alfred,

Core git requires objects to be able to fit into (virtual) memory. Adding more swap space should solve the problem for you, but this is not only a git-svn problem.

Fwiw, git-svn itself has always had a pretty strict "no slurping" policy.
