Did Git::Repository install without problems? What output gives running "perl -Ilib t/30stitch-repo.t" from the directory where the tarball was extracted? Show quoted text

Dist::Zilla shouldn't be required to install Git::FastExport. -- Philippe Bruhat (BooK) Your reputation is what you make of it... and what you choose to take with you. (Moral from Groo The Wanderer #48 (Epic))

As you could guess, I was getting desperate when I installed Dist::Zilla! Anyway, yes git::Repository installed fine without errors, I installed it earlier In running that command, I really get nothing other than 1..60 C:\strawberry\cpan\build\Git-FastExport-0.103-UNw9sE>perl -Ilib t/30stitch-repo. t 1..60 It too seems to hang, it's been running for maybe 10 minutes.

I do see things in git-test subdirectory C:\strawberry\cpan\build\Git-FastExport-0.103-ZCLgy2\git-test\0\A\.git If I cd into it and run git status, I see it's a repo same for C:\strawberry\cpan\build\Git-FastExport-0.103-ZCLgy2\git-test\_\A\.git So it is creating git repositories. Not sure where it's hanging though. On Thu, Apr 10, 2014 at 2:45 PM, marc towersap <marc.towersap@gmail.com>wrote: Show quoted text

I don't have a Windows box, which makes it hard for me to test. However I got some help on irc (irc.perl.org, I'm BooK there), and it seems it's the first `git fast-import` command that is blocking. I'm not exactly sure what the issue is. I wonder if it's related to CRLF line endings. Could you pick a random git repository and run: git fast-export --no-data master^.. and check what the line endings look like? Typically using an hex editor or something that can tell you if it's \012, \015 or a combination of the two. Another test we could try is to edit lib/Git/FastExport/Block.pm and replace the following line: my $LF = "\012"; By my $LF = "\n"; or my $LF = "\015\012"; And see if the test script still hangs. -- Philippe Bruhat (BooK) Even the most powerful being is at the mercy of the weakest.

OK, so after checking on a Windows box, it's not a line-ending issue. It seems to be a deadlock caused by the fact that we're reading from several subprocesses at the same time. I'll try to reproduce it with a simple case, using System::Command / IPC::Run (used by System::Command on Win32) and see if there's a way out of this. -- BooK
