2006-05-01built-in "git grep"Junio C Hamano
This attempts to set up built-in "git grep" to further reduce our dependence on the shell, while at the same time optionally allowing to run grep against object database. You could do funky things like these: git grep --cached -e pattern ;# grep from index git grep -e pattern master ;# or in a rev git grep -e pattern master next ;# or in multiple revs git grep -e pattern pu^@ ;# even like this with an ;# extension from another topic ;-) git grep -e pattern master..next ;# or even from rev ranges git grep -e pattern master~20:Documentation ;# or an arbitrary tree git grep -e pattern next:git-commit.sh ;# or an arbitrary blob Right now, it does not understand and/or obey many options grep should accept, and the pattern must be given with -e option due to the way the parameter parser is structured, both of which obviously need to be fixed for usability. But this is going in the right direction. The shell script version is one of the worst Portability offender in the git barebone Porcelainish; it uses xargs -0 to pass paths around and shell arrays to sift flags and parameters.

2006-04-26Makefile: remove and create libgit.a from scratch.Junio C Hamano
Foolishly I renamed diff.o around which caused an old diff.o taken out of libgit.a and got linked into resulting binary and exhibited mysterious breakage for many people. This borrows from the kernel Makefile (scripts/Makefile.build) to first remove the target and then recreate. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-22Libify diff-files.Junio C Hamano
This is the first installment to libify diff brothers. The updated diff-files uses revision.c::setup_revisions() infrastructure to parse its command line arguments, which means the pathname arguments are checked more strictly than before. The tests are adjusted to separate possibly missing paths from the rest of arguments with double-dashes, to show the kosher way. As Linus pointed out, renaming diff.c to diff-lib.c was simply stupid, so I am renaming it back. The new diff-lib.c is to contain pieces extracted from diff brothers.

Right now it split it into "builtin-log.c" for log-related commands ("log", "show" and "whatchanged"), and "builtin-help.c" for the informational commands (usage printing and "help" and "version").

2006-04-09log-tree: separate major part of diff-tree.Junio C Hamano
This separates out the part that deals with one-commit diff-tree (and --stdin form) into a separate log-tree module. There are two goals with this. The more important one is to be able to make this part available to "git log --diff", so that we can have a native "git whatchanged" command. Another is to simplify the commit log generation part simpler. Signed-off-by: Junio C Hamano <junkio@cox.net>

Introduce tree-walk.[ch] and move "struct tree_desc" and associated functions from various places. Rename DIFF_FILE_CANON_MODE(mode) macro to canon_mode(mode) and move it to cache.h. This macro returns the canonicalized st_mode value in the host byte order for files, symlinks and directories -- to be compared with a tree_desc entry. create_ce_mode(mode) in cache.h is similar but is intended to be used for index entries (so it does not work for directories) and returns the value in the network byte order.

* lt/diffgen: built-in diff: minimum tweaks builtin-diff: \No newline at end of file. Use a *real* built-in diff generator
2006-03-26Use a *real* built-in diff generatorLinus Torvalds
This uses a simplified libxdiff setup to generate unified diffs _without_ doing fork/execve of GNU "diff". This has several huge advantages, for example: Before: [torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null real 0m24.818s user 0m13.332s sys 0m8.664s After: [torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null real 0m4.563s user 0m2.944s sys 0m1.580s and the fact that this should be a lot more portable (ie we can ignore all the issues with doing fork/execve under Windows). Perhaps even more importantly, this allows us to do diffs without actually ever writing out the git file contents to a temporary file (and without any of the shell quoting issues on filenames etc etc). NOTE! THIS PATCH DOES NOT DO THAT OPTIMIZATION YET! I was lazy, and the current "diff-core" code actually will always write the temp-files, because it used to be something that you simply had to do. So this current one actually writes a temp-file like before, and then reads it into memory again just to do the diff. Stupid. But if this basic infrastructure is accepted, we can start switching over diff-core to not write temp-files, which should speed things up even further, especially when doing big tree-to-tree diffs. Now, in the interest of full disclosure, I should also point out a few downsides: - the libxdiff algorithm is different, and I bet GNU diff has gotten a lot more testing. And the thing is, generating a diff is not an exact science - you can get two different diffs (and you will), and they can both be perfectly valid. So it's not possible to "validate" the libxdiff output by just comparing it against GNU diff. - GNU diff does some nice eye-candy, like trying to figure out what the last function was, and adding that information to the "@@ .." line. libxdiff doesn't do that. - The libxdiff thing has some known deficiencies. In particular, it gets the "\No newline at end of file" case wrong. So this is currently for the experimental branch only. I hope Davide will help fix it. That said, I think the huge performance advantage, and the fact that it integrates better is definitely worth it. But it should go into a development branch at least due to the missing newline issue. Technical note: this is based on libxdiff-0.17, but I did some surgery to get rid of the extraneous fat - stuff that git doesn't need, and seriously cutting down on mmfile_t, which had much more capabilities than the diff algorithm either needed or used. In this version, "mmfile_t" is just a trivial <pointer,length> tuple. That said, I tried to keep the differences to simple removals, so that you can do a diff between this and the libxdiff origin, and you'll basically see just things getting deleted. Even the mmfile_t simplifications are left in a state where the diffs should be readable. Apologies to Davide, whom I'd love to get feedback on this all from (I wrote my own "fill_mmfile()" for the new simpler mmfile_t format: the old complex format had a helper function for that, but I did my surgery with the goal in mind that eventually we _should_ just do mmfile_t mf; buf = read_sha1_file(sha1, type, &size); mf->ptr = buf; mf->size = size; .. use "mf" directly .. which was really a nightmare with the old "helpful" mmfile_t, and really is that easy with the new cut-down interfaces). [ Btw, as any hawk-eye can see from the diff, this was actually generated with itself, so it is "self-hosting". That's about all the testing it has gotten, along with the above kernel diff, which eye-balls correctly, but shows the newline issue when you double-check it with "git-apply" ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-03-08Update http-push functionalityNick Hengeveld
This brings http-push functionality more in line with the ssh/git version, by borrowing bits from send-pack and rev-list to process refspecs and revision history in more standard ways. Also, the status of remote objects is determined using PROPFIND requests for the object directory rather than HEAD requests for each object - while it may be less efficient for small numbers of objects, this approach is able to get the status of all remote loose objects in a maximum of 256 requests.
