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.

NAME
|
|
----
|
|
git-bisect - Find the change that introduced a bug
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git bisect' start
|
|
'git bisect' bad <rev>
|
|
'git bisect' good <rev>
|
|
'git bisect' reset [<branch>]
|
|
'git bisect' visualize
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
This command uses 'git-rev-list --bisect' option to help drive
|
|
the binary search process to find which change introduced a bug,
|
|
given an old "good" commit object name and a later "bad" commit
|
|
object name.
|
|
|
|
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).
|
|
|
|
During the bisection process, you can say
|
|
|
|
git bisect visualize
|
|
|
|
to see the currently remaining suspects in `gitk`.
