Carl Worth	0f497e75f0	Eliminate confusing "won't bisect on seeked tree" failure This error message is very confusing---it doesn't tell the user anything about how to fix the situation. And the actual fix for the situation ("git bisect reset") does a checkout of a potentially random branch, (compared to what the user wants to be on for the bisect she is starting). The simplest way to eliminate the confusion is to just make "git bisect start" do the cleanup itself. There's no significant loss of safety here since we already have a general safety in the form of the reflog. Note: We preserve the warning for any cogito users. We do this by switching from .git/head-name to .git/BISECT_START for the extra state, (which is a more descriptive name anyway).

Johannes Schindelin	ce32660edc	bisect: allow starting with a detached HEAD Instead of insisting on a symbolic ref, bisect now accepts detached HEADs, too. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Christian Couder	fce0499fad	Bisect reset: do nothing when not bisecting. Before this patch, using "git bisect reset" when not bisecting did a "git checkout master" for no good reason. This also happened using "git bisect replay" when not bisecting because "bisect_replay" starts by calling "bisect_reset".

Christian Couder	947a604b01	Bisect reset: remove bisect refs that may have been packed. If refs were ever packed in the middle of bisection, the bisect refs were not removed from the "packed-refs" file. This patch fixes this problem by using "git update-ref -d $ref $hash" in "bisect_clean_state".

Christian Couder	71b0251cdd	Bisect run: "skip" current commit if script exit code is 125. This is incompatible with previous versions because an exit code of 125 used to mark current commit as "bad". But hopefully this exit code is not much used by test scripts or other programs. (126 and 127 are used by POSIX compliant shells to mean "found but not executable" and "command not found", respectively.)

Christian Couder	97e1c51e15	Bisect: implement "bisect skip" to mark untestable revisions. When there are some "skip"ped revisions, we add the '--bisect-all' option to "git rev-list --bisect-vars". Then we filter out the "skip"ped revisions from the result of the rev-list command, and we modify the "bisect_rev" var accordingly. We don't always use "--bisect-all" because it is slower than "--bisect-vars" or "--bisect". When we cannot find for sure the first bad commit because of "skip"ped commits, we print the hash of each possible first bad commit and then we exit with code 2.

Junio C Hamano	a6080a0a44	War on whitespace This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

Junio C Hamano	ab69e89c7e	t6030: grab commit object name as we go Instead of running rev-list and picking earlier lines using head/tail pipeline, grab commit object name as we build commits. This also removes a non POSIX use of tail with -linenum (more posixly-correct way to say it is "-n linenum") Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Christian Couder	f948792990	Bisect: rename "t/t6030-bisect-run.sh" to "t/t6030-bisect-porcelain.sh". [jc: also fix `0a5280a9` that incorrectly changed the title of one test.] Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	0a5280a9f4	git-bisect: allow bisecting with only one bad commit. 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.

Junio C Hamano	4f50671699	t6030: add a bit more tests to git-bisect Verify that git-bisect does not start before getting one bad and one good commit. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Christian Couder	38a47fd6e3	Bisect: teach "bisect start" to optionally use one bad and many good revs. 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.

Christian Couder	a17c410100	Bisect: implement "git bisect run <cmd>..." to automatically bisect. 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.
