# Bisect
|
|
|
|
Bisect can be used to identify commits that introduce a bug or regression in our
|
|
code.
|
|
|
|
It is most useful for when we know there is a problem in the code and we know
|
|
there was a point in the past where the bug did not exist. We can compare the
|
|
two points and try to identify where things went wrong.
|
|
|
|
We mark the last good revision and the first bad revision. Bisect will the reset
|
|
the code to the midpoint between the good and bad versions and let you test it.
|
|
You mark that as a good or bad version and then bisect repeats the process.
|
|
|
|
|
|
|
|
## Procedure
|
|
|
|
```
|
|
git bisect start
|
|
|
|
git bisect good <SHA, tag, branch>
|
|
|
|
git bisect bad <SHA, tag, branch>
|
|
```
