Hi all.
I am struggling with a git repository which I sync with an SVN repos
using git-svn. git-svn dcommit fails with (dump from git-svn 1.5.4.1):
Committing to svn://epia/tmp/Trunc ...
A modules/akismet
fatal: git-cat-file 5f726f311613171310226d9bf040765

Just to explain my setup. I've got an application that has shared
code. This shared code was previously accessed in SVN via an
svn:externals which pointed to a separate "shared code" svn
repository. This setup allowed me to share this code in several apps
whilst also giving me the ability to modify this shared code in any
single application and commit it to the "shared code" repos for use in
my other applications.
I've written an article on it here:
http://panthersoftware.com/articles/view/3/svn-s-svn-externals-to-git-s-submodule-for-rails-plugins
I've tried hacking git-svn but my Perl fu is weak. So I would
appreciate any pointers to help me solve this.
I've done the following hack:
sub valid_object {
#check if git-cat can process this sha1..if not then return false
my ($self, $sha1) = @_;
my $fh = IO::File->new_tmpfile or croak $!;
defined(my $pid = fork) or croak $!;
if (!$pid) {
open STDOUT, '>&', $fh or croak $!;
exec qw/git-cat-file blob/, $sha1 or croak $!;
}
waitpid $pid, 0;
if ($?) {
return 0;
} else {
return 1;
}
}
sub A {
my ($self, $m) = @_;
if ($self->valid_object($m->{sha1_b}) == 1) {
my ($dir, $file) = split_path($m->{file_b});
my $pbat = $self->ensure_path($dir);
my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat,
undef, -1);
print "\tA\t$m->{file_b}\n" unless $::_q;
$self->chg_file($fbat, $m);
$self->close_file($fbat,undef,$self->{pool});
}
}
I added sub valid_object to package SVN::Git::Editor. It is a brute
method to see if git-cat-file will choke on a particular sha1. I am
certain there is a more elegant method to check if a sha1 is actually
a submodule... I just haven't found it yet.
The above almost works but not quite:
$ git-svn2 dcommit
Committing to svn://epia/tmp/Trunc ...
fatal: git-cat-file 5f726f311613171310226d9bf0407656ad4a82f4: bad file

If you are attempting to commit merges, try running:
git rebase --interactive --preserve-merges refs/remotes/git-svn
Before dcommitting
"fatal: git-cat-file 5f726f311613171310226d9bf0407656ad4a82f4: bad
file" comes from sub valid_object and is for info only. I can see that
git-svn has bypassed the submodule as I was hoping.
Checking SVN's log I can see an empty commit (ie no files have been
uploaded). In Git, my Master branch is still ahead of of the
remotes/git-svn branch (ie not in synch with remotes/git-svn)
>From the above, I can see that I am so almost there... but just need
one final push to get me to the finishing line.
Is there anyway I can tell git-svn to ignore submodules?
Any hints, tips or help would be greatly appreciated.
Thank you in advance for any help.
