Add 'git-rev-parse' helper script It's an incredibly cheesy helper that changes human-readable revision arguments into the git-rev-list argument format. You can use it to do something like this: git-rev-list --pretty $(git-rev-parse --default HEAD "$@") which is what git-log-script will become. Here git-rev-parse will then allow you to use arguments like "v2.6.12-rc5.." or similar human-readable ranges. It's really quite stupid: "a..b" will be converted into "a" and "^b" if "a" and "b" are valid object pointers. And the "--default" case will be used if nothing but flags have been seen, so that you can default to a certain argument if there are no other ranges.

#include "cache.h"
Make rev-parse understand "extended sha1" syntax You can say "HEAD.p" for the "parent of HEAD". It nests, so HEAD.p2.p means parent of second parent of HEAD (which obviously depends on HEAD being a merge).

#include "commit.h"
Add "--all" flag to rev-parse that shows all refs And make git-rev-list just silently ignore non-commit refs if we're not asking for all objects.

[PATCH] Teach "git-rev-parse" about date-based cut-offs This adds the options "--since=date" and "--before=date" to git-rev-parse, which knows how to translate them into seconds since the epoch for git-rev-list. With this, you can do git log --since="2 weeks ago" or git log --until=yesterday to show the commits that have happened in the last two weeks or are older than 24 hours, respectively. The flags "--after=" and "--before" are synonyms for --since and --until, and you can combine them, so git log --after="Aug 5" --before="Aug 10" is a valid (but strange) thing to do.

Rationalize output selection in rev-parse. Earlier rounds broke 'whatchanged -p'. In attempting to fix this, make two axis of output selection in rev-parse orthogonal: --revs-only tells it not to output things that are not revisions nor flags that rev-list would take. --no-revs tells it not to output things that are revisions or flags that rev-list would take. --flags tells it not to output parameters that do not start with a '-'. --no-flags tells it not to output parameters that starts with a '-'. So for example 'rev-parse --no-revs -p arch/i386' would yield '-p arch/i386', while 'rev-parse --no-revs --flags -p archi/i386' would give just '-p'. Also the meaning of --verify has been made stronger. It now rejects anything but a single valid rev argument. Earlier it passed some flags through without complaining.

upload-pack: Do not choke on too many heads request. Cloning from a repository with more than 256 refs (heads and tags included) will choke, because upload-pack has a built-in limit of feeding not more than MAX_NEEDS (currently 256) heads to underlying git-rev-list. This is a problem when cloning a repository with many tags, like http://www.linux-mips.org/pub/scm/linux.git, which has 290+ tags. This commit introduces a new flag, --all, to git-rev-list, to include all refs in the repository. Updated upload-pack detects requests that ask more than MAX_NEEDS refs, and sends everything back instead. We may probably want to tweak the definitions of MAX_NEEDS and MAX_HAS, but that is a separate topic. Signed-off-by: Junio C Hamano <junkio@cox.net>

Downstream pack-objects will be changed to take these as hints to use the trees and blobs contained with them as base objects of resulting pack, producing an incomplete (not self-contained) pack. Such a pack cannot be used in .git/objects/pack (it is prevented by git-index-pack erroring out if it is fed to git-fetch-pack -k or git-clone-pack), but would be useful when transferring only small changes to huge blobs.

Add callback data to for_each_ref() family. This is a long overdue fix to the API for for_each_ref() family of functions. It allows the callers to specify a callback data pointer, so that the caller does not have to use static variables to communicate with the callback funciton. The updated for_each_ref() family takes a function of type int (*fn)(const char *, const unsigned char *, void *) and a void pointer as parameters, and calls the function with the name of the ref and its SHA-1 with the caller-supplied void pointer as parameters.

git's rev-parse.c function show_datestring presumes gnu date Ok. This is the insane patch to do this. It really isn't very careful, and the reason I call it "approxidate()" will become obvious when you look at the code. It is very liberal in what it accepts, to the point where sometimes the results may not make a whole lot of sense. It accepts "last week" as a date string, by virtue of "last" parsing as the number 1, and it totally ignoring superfluous fluff like "ago", so "last week" ends up being exactly the same thing as "1 week ago". Fine so far. It has strange side effects: "last december" will actually parse as "Dec 1", which actually _does_ turn out right, because it will then notice that it's not December yet, so it will decide that you must be talking about a date last year. So it actually gets it right, but it's kind of for the "wrong" reasons. It also accepts the numbers 1..10 in string format ("one" .. "ten"), so you can do "ten weeks ago" or "ten hours ago" and it will do the right thing. But it will do some really strange thigns too: the string "this will last forever", will not recognize anyting but "last", which is recognized as "1", which since it doesn't understand anything else it will think is the day of the month. So if you do gitk --since="this will last forever" the date will actually parse as the first day of the current month. And it will parse the string "now" as "now", but only because it doesn't understand it at all, and it makes everything relative to "now". Similarly, it doesn't actually parse the "ago" or "from now", so "2 weeks ago" is exactly the same as "2 weeks from now". It's the current date minus 14 days. But hey, it's probably better (and certainly faster) than depending on GNU date. So now you can portably do things like gitk --since="two weeks and three days ago" git log --since="July 5" git-whatchanged --since="10 hours ago" git log --since="last october" and it will actually do exactly what you thought it would do (I think). It will count 17 days backwards, and it will do so even if you don't have GNU date installed. (I don't do "last monday" or similar yet, but I can extend it to that too if people want). It was kind of fun trying to write code that uses such totally relaxed "understanding" of dates yet tries to get it right for the trivial cases. The result should be mixed with a few strange preprocessor tricks, and be submitted for the IOCCC ;) Feel free to try it out, and see how many strange dates it gets right. Or wrong. And if you find some interesting (and valid - not "interesting" as in "strange", but "interesting" as in "I'd be interested in actually doing this) thing it gets wrong - usually by not understanding it and silently just doing some strange things - please holler. Now, as usual this certainly hasn't been getting a lot of testing. But my code always works, no? Linus Signed-off-by: Junio C Hamano <junkio@cox.net>

git-rev-list: make --dense the default (and introduce "--sparse") This actually does three things: - make "--dense" the default for git-rev-list. Since dense is a no-op if no filenames are given, this doesn't actually change any historical behaviour, but it's logically the right default (if we want to prune on filenames, do it fully. The sparse "merge-only" thing may be useful, but it's not what you'd normally expect) - make "git-rev-parse" show the default revision control before it shows any pathnames. This was a real bug, but nobody would ever have noticed, because the default thing tends to only make sense for git-rev-list, and git-rev-list didn't use to take pathnames. - it changes "git-rev-list" to match the other commands that take a mix of revisions and filenames - it no longer requires the "--" before filenames (although you still need to do it if a filename could be confused with a revision name, eg "gitk" in the git archive) This all just makes for much more pleasant and obvous usage. Just doing a gitk t/ does the obvious thing: it will show the history as it concerns the "t/" subdirectory.

Fix error handling for nonexistent names When passing in a pathname pattern without the "--" separator on the command line, we verify that the pathnames in question exist. However, there were two bugs in that verification: - git-rev-parse would only check the first pathname, and silently allow any invalid subsequent pathname, whether it existed or not (which defeats the purpose of the check, and is also inconsistent with what git-rev-list actually does) - git-rev-list (and "git log" etc) would check each filename, but if the check failed, it would print the error using the first one, i.e.: [torvalds@g5 git]$ git log Makefile bad-file fatal: 'Makefile': No such file or directory instead of saying that it's 'bad-file' that doesn't exist.

[PATCH] Help scripts that use git-rev-parse to grok args with SP/TAB/LF The git-rev-parse command uses LF to separate each argument it parses, so its users at least need to set IFS to LF to be able to handle filenames with embedded SPs and TABs. Some commands, however, can take and do expect arguments with embedded LF, notably, "-S" (pickaxe) of diff family, so even this workaround does not work for them. When --sq flag to git-rev-parse is given, instead of showing one argument per line, it outputs arguments quoted for consumption with "eval" by the caller, to remedy this situation. As an example, this patch converts git-whatchanged to use this new feature. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Rationalize output selection in rev-parse. Earlier rounds broke 'whatchanged -p'. In attempting to fix this, make two axis of output selection in rev-parse orthogonal: --revs-only tells it not to output things that are not revisions nor flags that rev-list would take. --no-revs tells it not to output things that are revisions or flags that rev-list would take. --flags tells it not to output parameters that do not start with a '-'. --no-flags tells it not to output parameters that starts with a '-'. So for example 'rev-parse --no-revs -p arch/i386' would yield '-p arch/i386', while 'rev-parse --no-revs --flags -p archi/i386' would give just '-p'. Also the meaning of --verify has been made stronger. It now rejects anything but a single valid rev argument. Earlier it passed some flags through without complaining.

Add 'git-rev-parse' helper script It's an incredibly cheesy helper that changes human-readable revision arguments into the git-rev-list argument format. You can use it to do something like this: git-rev-list --pretty $(git-rev-parse --default HEAD "$@") which is what git-log-script will become. Here git-rev-parse will then allow you to use arguments like "v2.6.12-rc5.." or similar human-readable ranges. It's really quite stupid: "a..b" will be converted into "a" and "^b" if "a" and "b" are valid object pointers. And the "--default" case will be used if nothing but flags have been seen, so that you can default to a certain argument if there are no other ranges.

Update get_sha1() to grok extended format. Everybody envies rev-parse, who is the only one that can grok the extended sha1 format. Move the get_extended_sha1() out of rev-parse, rename it to get_sha1() and make it available to everybody else. The one I posted earlier to the list had one bug where it did not handle a name that ends with a digit correctly (it incorrectly tried the "Nth parent" path). This commit fixes it.

Fix filename verification when in a subdirectory When we are in a subdirectory of a git archive, we need to take the prefix of that subdirectory into accoung when we verify filename arguments. Noted by Matthias Lederhofer This also uses the improved error reporting for all the other git commands that use the revision parsing interfaces, not just git-rev-parse. Also, it makes the error reporting for mixed filenames and argument flags clearer (you cannot put flags after the start of the pathname list).
