Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.sh
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

Before commit d3c9634e, performing a "git svn rebase" that fetched a
change containing CRLFs corrupted the git-svn meta-data. This was
worked around in d3c9634e by setting core.autocrlf to "false" in the
per-repo config when initing the clone. However, if the config
variable was later changed, the corruption would still occur.
This patch tries to fix it while allowing core.autocrlf to be

The trouble is that we might reuse packs information for another

nevertheless going to be the same object. It merely makes object
existence detection through this method unreliable; it is duly noted

the closest sane alternative is to catch the dies in Git.pm by

The only "small" trouble is that Error.pm turns out sadly not to be
part of the standard distribution, and installation from CPAN is
a bother, especially if you can't install it system-wide. But since
it is very small, I've decided to just bundle it.

Instead of explicitly using the git wrapper to call external commands,
use the execv_git_cmd() function which will directly call whatever
needs to be called. GitBin option becomes useless so drop it.
This actually means the exec_path() thing I planned to use worthless
internally, but Jakub wants it in anyway and I don't mind, so...

This patch implements Git::exec_path() (as a direct XS call).

This patch introduces a very basic and barebone Git.pm module
with a sketch of how the generic interface would look like;
most functions are missing, but this should give some good base.
I will continue expanding it.
Most desirable now is more careful error reporting, generic_in() for feeding
input to Git commands and the repository() constructor doing some poking
with git-rev-parse to get the git directory and subdirectory prefix.
Those three are basically the prerequisities for converting git-mv.
I will send them as follow-ups to this patch.
Currently Git.pm just wraps up exec()s of Git commands, but even that
is not trivial to get right and various Git perl scripts do it in
various inconsistent ways. In addition to Git.pm, there is now also
Git.xs which provides barebone Git.xs for directly interfacing with
libgit.a, and as an example providing the hash_object() function using
libgit.
This adds the Git module, integrates it to the build system and as
an example converts the git-fmt-merge-msg.perl script to it (the result
is not very impressive since its advantage is not quite apparent in this
one, but I just picked up the simplest Git user around).
Compared to v3, only very minor things were fixed in this patch (some
whitespaces, a missing export, tiny bug in git-fmt-merge-msg.perl);
at first I wanted to post them as a separate patch but since this
is still only in pu, I decided that it will be cleaner to just resend
the patch.
My current working state is available all the time at

and an irregularily updated API documentation is at
