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).

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'.

git-rev-parse: add "--not" flag to mark subsequent heads negative If you have two lists of heads, and you want to see ones reachable from list $a but not from list $b, just do git-rev-list $(git-rev-parse $a --not $b) which is useful for both bisecting (where "b" would be the list of known good revisions, and "a" would be the latest found bad head) and for just seeing what the difference between two sets of heads are if you want to generate a pack-file for the difference.

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>

/* Output argument as a string, either SQ or normal */
[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.

[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>

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.

[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.

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.

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.

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.

[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>

Clean up work-tree handling The old version of work-tree support was an unholy mess, barely readable, and not to the point. For example, why do you have to provide a worktree, when it is not used? As in "git status". Now it works. Another riddle was: if you can have work trees inside the git dir, why are some programs complaining that they need a work tree? IOW it is allowed to call $ git --git-dir=../ --work-tree=. bla when you really want to. In this case, you are both in the git directory and in the working tree. So, programs have to actually test for the right thing, namely if they are inside a working tree, and not if they are inside a git directory. Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was specified, unless there is a repository in the current working directory. It does now. The logic to determine if a repository is bare, or has a work tree (tertium non datur), is this: --work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true, which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR ends in /.git, which overrides the directory in which .git/ was found. In related news, a long standing bug was fixed: when in .git/bla/x.git/, which is a bare repository, git formerly assumed ../.. to be the appropriate git dir. This problem was reported by Shawn Pearce to have caused much pain, where a colleague mistakenly ran "git init" in "/" a long time ago, and bare repositories just would not work.

introduce GIT_WORK_TREE to specify the work tree setup_gdg is used as abbreviation for setup_git_directory_gently. The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.

Mechanical conversion to use prefixcmp() This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>

[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.

Fix git-rev-parse over-eager errors Using "--verify" together with "--no-flags" makes perfect sense, but git-rev-parse would complain about it when it saw a flag, even though it would never actually use/output that flag.

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.

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.

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).
