Hi,
To be able to call commit-tree from a Perl program, I had to use
command_bidi_pipe() to pass the message on standard input, and get the
new commit id on standard output. The only problem I have is that the
method doesn't work (or at least, doesn't work like the other
command_... methods).
sub command_bidi_pipe {
my ($pid, $in, $out);
$pid = open2($in, $out, 'git', @_);
return ($pid, $in, $out, join(' ', @_));
}
First, it calls git in the current working dir, when all the other
command_... methods do the appropriate chdir depending on the Git object.
Second, it can't be used as a method, since $self is not removed from @_
before calling open2, leading to errors such as this one:
git: 'Git=HASH(0x82f898c)' is not a git-command. See 'git --help'.
Third, no access is given to STDERR (open3 may help).
I'm very sorry to complain without proposing a patch.
I think solving the current directory problem is probably going to be
difficult with open2/open3, since open2 does the fork+exec, whereas Git.pm
handles the fork+chdir+exec itself for the other command_... methods.
And so there is no room to chdir when calling open2.
