2006-05-19Add builtin "git rm" commandLibravatar Linus Torvalds1-0/+1
This changes semantics very subtly, because it adds a new atomicity guarantee. In particular, if you "git rm" several files, it will now do all or nothing. The old shell-script really looped over the removed files one by one, and would basically randomly fail in the middle if "-f" was used and one of the files didn't exist in the working directory. This C builtin one will not re-write the index after each remove, but instead remove all files at once. However, that means that if "-f" is used (to also force removal of the file from the working directory), and some files have already been removed from the workspace, it won't stop in the middle in some half-way state like the old one did. So what happens is that if the _first_ file fails to be removed with "-f", we abort the whole "git rm". But once we've started removing, we don't leave anything half done. If some of the other files don't exist, we'll just ignore errors of removal from the working tree. This is only an issue with "-f", of course. I think the new behaviour is strictly an improvement, but perhaps more importantly, it is _different_. As a special case, the semantics are identical for the single-file case (which is the only one our test-suite seems to test). The other question is what to do with leading directories. The old "git rm" script didn't do anything, which is somewhat inconsistent. This one will actually clean up directories that have become empty as a result of removing the last file, but maybe we want to have a flag to decide the behaviour?

2006-05-01built-in "git grep"Libravatar Junio C Hamano1-0/+1
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.

2006-04-30git builtin "push"Libravatar Linus Torvalds1-0/+1
This adds a builtin "push" command, which is largely just a C'ification of the "git-push.sh" script. Now, the reason I did it as a built-in is partly because it's yet another step on relying less on shell, but it's actually mostly because I've wanted to be able to push to _multiple_ repositories, and the most obvious and simplest interface for that would seem be to just have a "remotes" file that has multiple URL entries. (For "pull", having multiple entries should either just select the first one, or you could fall back on the others on failure - your choice). And quite frankly, it just became too damn messy to do that in shell. Besides, we actually have a fair amount of infrastructure in C, so it just wasn't that hard to do. Of course, this is almost totally untested. It probably doesn't work for anything but the one trial I threw at it. "Simple" doesn't necessarily mean "obviously correct".

When I split out the builtin commands into their own files, I left the include of <sys/ioctl.h> in git.c rather than moving it to the file that needed it (builtin-help.c). Nobody seems to have noticed, because everything still worked, but because the TIOCGWINSZ macro was now no longer defined when compiling the "term_columns()" function, it would no longer automatically notice the terminal size unless your system used the ancient "COLUMNS" environment variable approach.

2006-04-19git log: don't do merge diffs by defaultLibravatar Linus Torvalds1-2/+0
I personally prefer "ignore_merges" to be on by default, because quite often the merge diff is distracting and not interesting. That's true both with "-p" and with "--stat" output. If you want output from merges, you can trivially use the "-m", "-c" or "--cc" flags to tell that you're interested in merges, which also tells the diff generator what kind of diff to do (for --stat, any of the three will do, of course, but they differ for plain patches or for --patch-with-stat). This trivial patch just removes the two lines that tells "git log" not to ignore merges. It will still show the commit log message, of course, due to the "always_show_header" part.

Ok, this was nastier than expected, just because the dependencies between the different log-printing stuff were absolutely _everywhere_, but here's a patch that does exactly that. The patch is not very easy to read, and the "--patch-with-stat" thing is still broken (it does not call the "show_log()" thing properly for merges). That's not a new bug. In the new world order it _should_ do something like if (rev->logopt) show_log(rev, rev->logopt, "---\n"); but it doesn't. I haven't looked at the --with-stat logic, so I left it alone. That said, this patch removes more lines than it adds, and in particular, the "cmd_log_wc()" loop is now a very clean: while ((commit = get_revision(rev)) != NULL) { log_tree_commit(rev, commit); free(commit->buffer); commit->buffer = NULL; } so it doesn't get much prettier than this. All the complexity is entirely hidden in log-tree.c, and any code that needs to flush the log literally just needs to do the "if (rev->logopt) show_log(...)" incantation. I had to make the combined_diff() logic take a "struct rev_info" instead of just a "struct diff_options", but that part is pretty clean. This does change "git whatchanged" from using "diff-tree" as the commit descriptor to "commit", and I changed one of the tests to reflect that new reality. Otherwise everything still passes, and my other tests look fine too. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

This uses the "--no-walk" flag that I never actually implemented (but I'm sure I mentioned it) to make "git show" be essentially the same thing as "git whatchanged --no-walk". It just refuses to add more interesting parents to the revision walking history, so you don't actually get any history, you just get the commit you asked for. I was going to add "--no-walk" as a real argument flag to git-rev-list too, but I'm not sure anybody actually needs it. Although it might be useful for porcelain, so I left the door open.

2006-04-15Support "git cmd --help" syntaxLibravatar Linus Torvalds1-0/+6
The "--help" argument is special, in that it is (along with "--version") in that is taken by the "git" program itself rather than the sub-command, and thus we've had the syntax "git --help cmd". However, as anybody who has ever used CVS or some similar devil-spawn program, it's confusing as h*ll when options before the sub-command act differently from options after the sub-command, so this quick hack just makes it acceptable to do "git cmd --help" instead, and get the exact same result. It may be hacky, but it's simple and does the trick. Of course, this does not help if you use one of the non-builtin commands without using the "git" helper. Ie you won't be getting a man-page just because you do "git-rev-list --help". Don't expect us to be quite _that_ helpful.

2006-04-14Common option parsing for "git log --diff" and friendsLibravatar Linus Torvalds1-70/+13
This basically does a few things that are sadly somewhat interdependent, and nontrivial to split out - get rid of "struct log_tree_opt" The fields in "log_tree_opt" are moved into "struct rev_info", and all users of log_tree_opt are changed to use the rev_info struct instead. - add the parsing for the log_tree_opt arguments to "setup_revision()" - make setup_revision set a flag (revs->diff) if the diff-related arguments were used. This allows "git log" to decide whether it wants to show diffs or not. - make setup_revision() also initialize the diffopt part of rev_info (which we had from before, but we just didn't initialize it) - make setup_revision() do all the "finishing touches" on it all (it will do the proper flag combination logic, and call "diff_setup_done()") Now, that was the easy and straightforward part. The slightly more involved part is that some of the programs that want to use the new-and-improved rev_info parsing don't actually want _commits_, they may want tree'ish arguments instead. That meant that I had to change setup_revision() to parse the arguments not into the "revs->commits" list, but into the "revs->pending_objects" list. Then, when we do "prepare_revision_walk()", we walk that list, and create the sorted commit list from there. This actually cleaned some stuff up, but it's the less obvious part of the patch, and re-organized the "revision.c" logic somewhat. It actually paves the way for splitting argument parsing _entirely_ out of "revision.c", since now the argument parsing really is totally independent of the commit walking: that didn't use to be true, since there was lots of overlap with get_commit_reference() handling etc, now the _only_ overlap is the shared (and trivial) "add_pending_object()" thing. However, I didn't do that file split, just because I wanted the diff itself to be smaller, and show the actual changes more clearly. If this gets accepted, I'll do further cleanups then - that includes the file split, but also using the new infrastructure to do a nicer "git diff" etc. Even in this form, it actually ends up removing more lines than it adds. It's nice to note how simple and straightforward this makes the built-in "git log" command, even though it continues to support all the diff flags too. It doesn't get much simpler that this. I think this is worth merging soonish, because it does allow for future cleanup and even more sharing of code. However, it obviously touches "revision.c", which is subtle. I've tested that it passes all the tests we have, and it passes my "looks sane" detector, but somebody else should also give it a good look-over.

2006-04-13Use less memory in "git log"Libravatar Linus Torvalds1-0/+2
This trivially avoids keeping the commit message data around after we don't need it any more, avoiding a continually growing "git log" memory footprint. It's not a huge deal, but it's somewhat noticeable. For the current kernel tree, doing a full "git log" I got - before: /usr/bin/time git log > /dev/null 0.81user 0.02system 0:00.84elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+8851minor)pagefaults 0swaps - after: /usr/bin/time git log > /dev/null 0.79user 0.03system 0:00.83elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+5039minor)pagefaults 0swaps ie the touched pages dropped from 8851 to 5039. For the historic kernel archive, the numbers are 18357->11037 minor page faults. We could/should in theory free the commits themselves, but that's really a lot harder, since during revision traversal we may hit the same commit twice through different children having it as a parent, even after we've shown it once (when that happens, we'll silently ignore it next time, but we still need the "struct commit" to know). And as the commit message data is clearly the biggest part of the commit, this is the really easy 60% solution.
