2005-09-08Big tool rename.Junio C Hamano
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.

2005-08-30'git bisect visualize'Junio C Hamano
Linus says: I'm testing bisection to find a bug that causes my G5 to no longer boot, and during the process have found this command line very nice: gitk bisect/bad --not $(cd .git/refs ; ls bisect/good-*) it basically shows the state of bisection with the known bad commit as the top, and cutting off all the good commits - so what you see are the potential buggy commits.

2005-08-30[PATCH] Fix bisection terminating conditionLinus Torvalds
When testing bisection and using gitk to visualize the result, it was obvious that the termination condition was broken. We know what the bad entry is only when the bisection ends up telling us to test the known-bad entry again. Also, add a safety net: if somebody marks as good something that includes the known-bad point, we now notice and complain, instead of writing an empty revision to the new bisection branch.

Some callers to rev-parse were using the output selection flags inconsistently. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-08-04git-bisect termination condition fix.Junio C Hamano
When I munged the original from Linus, which did not terminate when the last bisect to check happened to be a bad one, to terminate, I seem to have botched the end result to pick. Thanks for Sanjoy Mahajan for a good reproduction recipe to diagnose this. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-07-30[PATCH] Making it easier to find which change introduced a bugLinus Torvalds
This adds a new "git bisect" command. - "git bisect start" start bisection search. - "git bisect bad <rev>" mark some version known-bad (if no arguments, then current HEAD) - "git bisect good <revs>..." mark some versions known-good (if no arguments, then current HEAD) - "git bisect reset <branch>" done with bisection search and go back to your work (if no arguments, then "master"). The way you use it is: git bisect start git bisect bad # Current version is bad git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version # tested that was good When you give at least one bad and one good versions, it will bisect the revision tree and say something like: Bisecting: 675 revisions left to test after this and check out the state in the middle. Now, compile that kernel, and boot it. Now, let's say that this booted kernel works fine, then just do git bisect good # this one is good which will now say Bisecting: 337 revisions left to test after this and you continue along, compiling that one, testing it, and depending on whether it is good or bad, you say "git bisect good" or "git bisect bad", and ask for the next bisection. Until you have no more left, and you'll have been left with the first bad kernel rev in "refs/bisect/bad". Oh, and then after you want to reset to the original head, do a git bisect reset to get back to the master branch, instead of being in one of the bisection branches ("git bisect start" will do that for you too, actually: it will reset the bisection state, and before it does that it checks that you're not using some old bisection branch). Not really any harder than doing series of "quilt push" and "quilt pop", now is it? [jc: This patch is a rework based on what Linus posted to the list. The changes are: - The original introduced four separate commands, which was three too many, so I merged them into one with subcommands. - Since the next thing you would want to do after telling it "bad" and "good" is always to bisect, this version does it automatically for you. - I think the termination condition was wrong. The original version checked if the set of revisions reachable from next bisection but not rechable from any of the known good ones is empty, but if the current bisection was a bad one, this would not terminate, so I changed it to terminate it when the set becomes a singleton or empty. - Removed the use of shell array variable. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
