Ævar Arnfjörð Bjarmason 9e20442298 xdiff-interface: allow early return from xdiff_emit_line_fn 
Finish the change started in the preceding commit and allow an early
return from "xdiff_emit_line_fn" callbacks, this will allows
diffcore-pickaxe.c to save itself redundant work.

Our xdiff interface also had the limitation of not being able to abort
early since the beginning, see d9ea73e056 (combine-diff: refactor
built-in xdiff interface., 2006-04-05). Although at that time
"xdiff_emit_line_fn" was called "xdiff_emit_consume_fn", and
"xdiff_emit_hunk_fn" didn't exist yet.

There was some work in this area of xdiff-interface.[ch] recently with
3b40a090fd (diff: avoid generating unused hunk header lines,
2018-11-02) and 7c61e25fbf (diff: use hunk callback for word-diff,
2018-11-02).

In combination those two changes allow us to not do any work on the
hunks and diff at all, but didn't change the status quo with regards
to consumers that e.g. want the diff lines, but might want to abort
early.

Whereas now we can abort e.g. on the first "-line" of a 1000 line diff
if that's all we needed.

This interface is rather scary as noted in the comment to
xdiff-interface.h being added here, as noted there a future change
could add more exit codes, and hack xdl_emit_diff() and friends to
ignore or skip things more selectively as a result.

I did not see an inherent reason for why xdl_emit_{diffrec,record}()
could not be changed to ferry the "xdiff_emit_line_fn" error code
upwards instead of returning -1 on all "ret < 0".

But doing so would require corresponding changes in xdl_emit_diff(),
xdl_diff(). I didn't see any issue with narrowly doing that to
accomplish what I needed here, but it would leave xdiff's own return
values in an inconsistent state.

Instead I've left it at returning a more conventional (for git's own
codebase) 1 for an early return, and translating it (or rather, all
non-zero) to -1 for xdiff's consumption.

The reason for most of the "stop" complexity in xdiff_outf() is
because we want to be able to abort early, but do so in a way that
doesn't skip the appropriate strbuf_reset() invocations.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

  • random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
  • stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
  • "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
  • "goddamn idiotic truckload of sh*t": when it breaks
