Hi,
I had some issues while converting our current SVN repository to a GIT
repository. The old repository has a lot of strange history in it making
it far from easy to convert it but for some issues I had to modify the
convert scripts.
As I don't know the internals of GIT or git-svn enough I don't know if
these are actually bugs or not. I will also not produce and submit
patches to fix this as I don't know enough Perl to know if maybe it can
be solved in a better way or that it should be solved at all.
1. issue with git-svn dying because git could not find the refname. I
noticed that in the function resolve_local_globs it was actually passing
desanitized names to the cmt_metadata function, so I changed the code to
use sanitized names, trying to keep the rest of the script (which I
don't pretend to understand) intact:
sub resolve_local_globs {
my ($url, $fetch, $glob_spec) = @_;
return unless defined $glob_spec;
my $ref = $glob_spec->{ref};
my $path = $glob_spec->{path};
foreach (command(qw#for-each-ref --format=%(refname) refs/#)) {
next unless m#^$ref->{regex}$#;
my $p = $1;
my $pathname = $path->full_path($p);
my $svnpathname = desanitize_refname($pathname);
my $refname = $ref->full_path($p);
my $svnrefname = desanitize_refname($refname);
if (my $existing = $fetch->{$svnpathname}) {
if ($existing ne $svnrefname) {
die "Refspec conflict:\n",
"existing: $existing\n",
" globbed: $svnrefname\n";
}
my $u = (::cmt_metadata("$refname"))[0];
$u =~ s!^\Q$url\E(/|$)!! or die
"$svnrefname: '$url' not found in '$u'\n";
if ($pathname ne $u) {
warn "W: Refspec glob conflict ",
"(ref: $svnrefname):\n",
"expected path: $pathname\n",
" real path: $u\n",
"Continuing ahead with $u\n";
next;
}
} else {
$fetch->{$svnpathname} = $svnrefname;
}
}
}
2. issue with an @ being present in a branch name. A first branch was
created just fine, but a second branch was created from that branch
which failed.
The following message (simplified for confidentiality reasons) was
shown while trying to branch 'blabla bla@bla blabla' to 'blabla blabla'
Found possible branch point:
svn://localhost/path/to/branch/blabla%20bla@bla%20blabla =>
svn://localhost/path/to/branches/blabla%20blabla, 13486
refs/remotes/origin/branches/blabla bla@bla blabla: 'svn://localhost'
not found in 'svn://bla%20blabla'
I found out that the git-svn-id was actually being wrongly initiated to
'svn://bla%20blabla'. This is due to a mistake in the regex that is used
in remove_username.
It was:
$_[0] =~ s{^([^:]*://)[^@]+@}{$1};
I changed it to
$_[0] =~ s{^([^:]*://)[^@/]+@}{$1};
And it works.
I did all this using the standard Git package for Windows, release
1.8.5.2
PS: I tried to send this from my work email several times but I think
the mail server can't handle the greylisting so I apologize if the mails
still end up in the list.
