Hi
Thanks for reply, but sorry I don't know how to do that - I don't have the git source code or know how to debug it.
Is there another way I can capture logging/debugging information while running "git svn clone" and send it to you?
Thanks

That "Permission denied" looks scary. Don't know how git-svn gets into this, but try with this patch on top:
diff --git a/perl/Git.pm b/perl/Git.pm
index d856930b2e..f5d15895d3 100644
--- a/perl/Git.pm
+++ b/perl/Git.pm
@@ -926,7 +926,13 @@ sub hash_and_insert_object {
throw Error::Simple("out pipe went bad");
}
- chomp(my $hash = <$in>);
+ my $hash = <$in>;
+ unless (defined $hash) {
+ sub noes { die "blah" }
+ noes();
+ } else {
+ chomp($hash);
+ }
unless (defined($hash)) {
$self->_close_hash_and_insert_object();
throw Error::Simple("in pipe went bad");
Then run:
perl -d $(git --exec-path)/git-svn
Set a breakpoint at that "noes" with:
DB<1> b Git::noes
Continue:
DB<2> c
Then when it stops there get a backtrace with "T":
DB<2> T
@ = DB::DB called from file 'perl/Git.pm' line 931
. = Git::noes() called from file 'perl/Git.pm' line 932
. = Git::hash_and_insert_object(ref(Git), 'Makefile') called from -e line 1
And see if you can get any other relevant info out of the debugger. See "perldoc perldebug".
