--bisect::
Limit output to the one commit object which is roughly halfway
between the included and excluded commits. Thus, if 'git-rev-list
- --bisect foo ^bar ^baz' outputs 'midpoint', the output
- of 'git-rev-list foo ^midpoint' and 'git-rev-list midpoint
- ^bar ^baz' would be of roughly the same length. Finding the change
+ --bisect foo {caret}bar {caret}baz' outputs 'midpoint', the output
+ of 'git-rev-list foo {caret}midpoint' and 'git-rev-list midpoint
+ {caret}bar {caret}baz' would be of roughly the same length.
+ Finding the change
which introduces a regression is thus reduced to a binary search:
repeatedly generate and test new 'midpoint's until the commit chain
is of length one.
