* git-bisect: allow bisecting with only one bad commit.Junio C Hamano2007-04-061-34/+53
| | | | | | | | | | | | | | | | This allows you to say: git bisect start git bisect bad $bad git bisect next to start bisection without knowing a good commit. This would have you try a commit that is half-way since the beginning of the history, which is rather wasteful if you already know a good commit, but if you don't (or your history is short enough that you do not care), there is no reason not to allow this.

* git-bisect: modernizationJunio C Hamano2007-04-051-5/+4
| | | | | | | This slightly modernizes the bisect script to use show-ref/for-each-ref instead of looking into $GIT_DIR/refs files directly. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Bisect: teach "bisect start" to optionally use one bad and many good revs.Christian Couder2007-04-051-23/+82
| | | | | | | | | | | | | | | | | | | | | | | | | One bad commit is fundamentally needed for bisect to run, and if we beforehand know more good commits, we can narrow the bisect space down without doing the whole tree checkout every time we give good commits. This patch implements: git bisect start [<bad> [<good>...]] [--] [<pathspec>...] as a short-hand for this command sequence: git bisect start git bisect bad $bad git bisect good $good1 $good2... On the other hand, there may be some confusion between revs (<bad> and <good>...) and <pathspec>... if -- is not used and if an invalid rev or a pathspec that looks like a rev is given.

* Bisect: Improve error message in "bisect_next_check".Christian Couder2007-03-291-7/+9

* Bisect: add checks at the beginning of "git bisect run".Christian Couder2007-03-271-0/+8
| | | | | | | | | | | | We may be able to "run" with only one good revision given and then verify that the result of the first run is bad. And perhaps also the other way around. But for now let's check that we have at least one bad and one good revision before we start to run.

* git-bisect.sh: properly dq $GIT_DIRJunio C Hamano2007-03-231-1/+1

* git-bisect: typofixJunio C Hamano2007-03-231-1/+1
| | | | | | | | The branch you are on while bisecting is always "bisect", and checking for "refs/heads/bisect*" is wrong. Only check if it is exactly "refs/heads/bisect". Signed-off-by: Junio C Hamano <junkio@cox.net>
* Bisect: implement "git bisect run <cmd>..." to automatically bisect.Christian Couder2007-03-231-3/+51
| | | | | | | | | | | | This idea was suggested by Bill Lear (Message-ID: <17920.38942.364466.642979@lisa.zopyra.com>) and I think it is a very good one. This patch adds a new test file for "git bisect run", but there is currently only one basic test.

* Bisect: convert revs given to good and bad to commitsUwe Kleine-König2007-03-231-2/+2
| | | | | | | | | Without this the rev could be (e.g.) a tag and then the condition to end the bisect might fail and you have to check the already known to be bad revision once more. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Junio C Hamano <junkio@cox.net>

* | Properly git-bisect reset after bisecting from non-master headPetr Baudis2006-02-121-3/+14
|/ | | | | | | | | | | | | | | | | | git-bisect reset without an argument would return to master even if the bisecting started at a non-master branch. This patch makes it save the original branch name to .git/head-name and restore it afterwards. This is also compatible with Cogito and cg-seek, so cg-status will show that we are seeked on the bisect branch and cg-reset will properly restore the original branch. git-bisect start will refuse to work if it is not on a bisect but .git/head-name exists; this is to protect against conflicts with other seeking tools.

* Usage message clean-up, take #2Fredrik Kuivinen2005-12-141-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | There were some problems with the usage message clean-up patch series. I hadn't realised that subdirectory aware scripts can't source git-sh-setup. I propose that we change this and let the scripts which are subdirectory aware set a variable, SUBDIRECTORY_OK, before they source git-sh-setup. The scripts will also set USAGE and possibly LONG_USAGE before they source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE. If we go this way it's easy to catch --help in git-sh-setup, print the (long) usage message to stdout and exit cleanly. git-sh-setup can define a 'usage' shell function which can be called by the scripts to print the short usage string to stderr and exit non-cleanly. It will also be easy to change $0 to basename $0 or something else, if would like to do that sometime in the future. What follows is a patch to convert a couple of the commands to this style. If it's ok with everyone to do it this way I will convert the rest of the scripts too. [jc: thrown in to proposed updates queue for comments.] Signed-off-by: Junio C Hamano <junkio@cox.net>
* Use printf rather than echo -n.Jason Riedy2005-12-061-1/+1
| | | | | | | | | | | | | | | | | | On AIX, there is no -n option to the system's echo. Instead, it needs the '\c' control character. We could replace echo -n "foo" with echo -e "foo\c" but printf is recommended by most man pages. Tested on AIX 5.3, Solaris 8, and Debian. [jc: futureproofed two instances that uses variable with '%s' so later feeding different messages would not break things too easily; others are emitting literal so whoever changes the literal ought to notice more easily so they are safe.] Signed-off-by: E.

* bisect: limit the searchspace by pathspecsLinus Torvalds2005-11-281-5/+5
| | | | | | | | | | | | | | | | | | | | | | | It was surprisingly easy to do. git bisect start <pathspec> followed by all the normal "git bisect good/bad" stuff. Almost totally untested, and I guarantee that if your pathnames have spaces in them (or your GIT_DIR has spaces in it) this won't work. I don't know how to fix that, my shell programming isn't good enough. This involves small changes to make "git-rev-list --bisect" work in the presense of a pathspec limiter, and then truly trivial (and that's the broken part) changes to make "git bisect" save away and use the pathspec. I tried one bisection, and a "git bisect visualize", and it all looked correct. But hey, don't be surprised if it has problems. Linus Signed-off-by: Junio C Hamano <junkio@cox.net>
* git-sh-setup: die if outside git repository.Junio C Hamano2005-11-251-1/+1
| | | | | | | | Now all the users of this script detect its exit status and die, complaining that it is outside git repository. So move the code that dies from all callers to git-sh-setup script. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Add git-symbolic-refJunio C Hamano2005-10-011-3/+4
| | | | | | | | | | | | | This adds the counterpart of git-update-ref that lets you read and create "symbolic refs". By default it uses a symbolic link to represent ".git/HEAD -> refs/heads/master", but it can be compiled to use the textfile symbolic ref. The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah .git/HEAD' have been converted to use new git-symbolic-ref command, so that they can deal with either implementation.

* Do not fail after calling bisect_auto_next()Junio C Hamano2005-09-171-1/+1
| | | | | | | | | As a convenience measure, 'bisect bad' or 'bisect good' automatically does 'bisect next' when it knows it can, but the result of that test to see if it can was leaking through as the exit code from the whole thing, which was bad. Noticed by Anton Blanchard. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Keep bisection log so that it can be replayed later.Junio C Hamano2005-09-101-3/+47
| | | | | | | | | The 'git bisect' command was very unforgiving in that once you made a mistake telling it good/bad it was very hard to take it back. Keep a log of what you told it in an earlier session, so that it can be replayed after removing everything after what you botched last time. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Big tool rename.Junio C Hamano2005-09-071-0/+178
As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.
