Petr Baudis	d43ba46807	Git.pm: Implement options for the command interface This gives the user a way to easily pass options to the command routines. Currently only the STDERR option is implemented and can be used to adjust what shall be done with error output of the called command (most usefully, it can be used to silence it).

Petr Baudis	d79850e1fd	Git.pm: Enhance the command_pipe() mechanism Rename command_pipe() to command_output_pipe(), outsource the functionality to _command_common_pipe(). Add command_input_pipe(). Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Petr Baudis	8b9150e3e3	Git.pm: Handle failed commands' output Currently if an external command returns error exit code, a generic exception is thrown and there is no chance for the caller to retrieve the command's output. This patch introduces a Git::Error::Command exception class which is thrown in this case and contains both the error code and the captured command output. You can use the new git_cmd_try statement to fatally catch the exception while producing a user-friendly message. It also adds command_close_pipe() for easier checking of exit status of a command we have just a pipe handle of. It has partial forward dependency on the next patch, but basically only in the area of documentation.

Petr Baudis	97b16c0674	Git.pm: Better error handling So far, errors just killed the whole program and in case of an error inside of libgit it would be totally uncatchable. This patch makes Git.pm throw standard Perl exceptions instead. In the future we might subclass Error to Git::Error or something but for now Error::Simple is more than enough.

Petr Baudis	5c4082fd68	Add Error.pm to the distribution I have been thinking about how to do the error reporting the best way and after scraping various overcomplicated concepts, I have decided that by far the most elegant way is to throw Error exceptions; the closest sane alternative is to catch the dies in Git.pm by enclosing the calls in eval{}s and that's really _quite_ ugly. 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. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Petr Baudis	63df97ae7b	Git.pm: Implement Git::version() Git::version() returns the Git version string. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Petr Baudis	8062f81c2d	Git.pm: Call external commands using execv_git_cmd() 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...

Petr Baudis	b1edc53d06	Introduce Git.pm (v4) 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 http://pasky.or.cz/~xpasky/git-perl/Git.pm and an irregularily updated API documentation is at http://pasky.or.cz/~xpasky/git-perl/Git.html Many thanks to Jakub Narebski, Junio and others for their feedback.
