The command takes various subcommands, and different options depending
|
||||
on the subcommand:
|
||||
|
||||
git bisect start [<paths>...]
|
||||
git bisect start [<bad> [<good>...]] [--] [<paths>...]
|
||||
git bisect bad <rev>
|
||||
git bisect good <rev>
|
||||
git bisect reset [<branch>]

Then compile and test the one you chose to try. After that, tell

Cutting down bisection by giving more parameters to bisect start

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can further cut down the number of trials if you know what part of
|
||||
the tree is involved in the problem you are tracking down, by giving
|
||||
paths parameters when you say `bisect start`, like this:
|
||||
|
||||
------------
|
||||
$ git bisect start arch/i386 include/asm-i386
|
||||
$ git bisect start -- arch/i386 include/asm-i386
|
||||
------------
|
||||
|
||||
If you know beforehand more than one good commits, you can narrow the
|
||||
bisect space down without doing the whole tree checkout every time you
|
||||
give good commits. You give the bad revision immediately after `start`
|
||||
and then you give all the good revisions you have:
|
||||
|
||||
------------
|
||||
$ git bisect start v2.6.20-rc6 v2.6.20-rc4 v2.6.20-rc1 --
|
||||
# v2.6.20-rc6 is bad
|
||||
# v2.6.20-rc4 and v2.6.20-rc1 are good
|
||||
