Hi,

Just wanted to pass on a few reports about git-svn dying with SIGPIPE when trying to fetch large repositories. It seems to fetch a few revisions, then die; the repositories can eventually be fetched successfully by restarting 'git svn fetch' again and again.

Some bug reporters have been very patient, but I don’t really know where to look or ask in solving this. Attempts at tracing so far have given either too little or too much information to make any sense.

The problem goes back at least to v1.5.6.5.

At the end of the git-svn process’s life, the last few function calls are these:

 - SVN::Ra::Reporter::finish_report and related functions
 - _p_apr_pool_t::DESTROY (libsvn-perl cleaning up, presumably)
 - SVN::Ra::Callbacks::open_tmp_file, called from
   SVN::_Ra::svn_ra_do_update, called from
   Git::SVN::Ra::do_update, called from
   Git::SVN::Ra::gs_do_update
 - Git::SVN::_set_repos_root
 - starting a 'git update-index -z --index-info' to feed commands to

Maybe /tmp is filling up? It is hard to know, since the SIGPIPE stops everything and we do not get any nice, simple error message describing what read or write would have received EPIPE.

See <http://bugs.debian.org/526989>, <http://bugs.debian.org/540150>, <http://thread.gmane.org/gmane.comp.version-control.git/85868/>.

Any insights?
