Hey all,

I've also got my work on a branch in my repo, if that helps to look at
things, https://gitlab.com/olliver/git/-/tree/skip_bisect

Also included is a script to be used as an example. I opted to use
`git show`, which is nice because it works both on commits, but also
on notes.

Anyway, any thoughts on the bellow before I send the full series?

I would not write get_skip_when() before studying the same file to
see if there already is a helper to read the whole file used in the
vicinity (like strbuf_read_file(), perhaps).

Fair enough. I'm a little worried about optimization vs readability. I think it makes it mre clear what the code does in its current form; but I'll investigate. Bisecting shouldn't be a computational often happening thing, so I'm not to worried about performance. But I'm not too familiar with the git code base, so I don't know either :p

If you search builtin/bisect.c you'll see some existing callers of strbuf_read_file() that read other files like BISECT_START. Those callers should give you an idea of how to use it.


I do not have enough concentration to follow changes to
bisect_auto_next() is reasonable.  Especially I do not know why
"bisect-skip_when" wants to exist and what it is trying to do,
besides the fact that its name looks horrible ;-).

naming things, sure. I can look into this absolutly :)

For me it's not just the name but the whole hook thing - do we really need that rather than just the command line option?

The other thing I wondered about is the exit code handling for the "--skip-when" script. In Junio's example in an earlier message he used a successful exit to mean "skip this commit" and an unsuccessful exit to mean "test this commit". To me that matches the name of the option - we skip when the script given to "--skip-when" is successful. Copying the mechanism used by "git bisect run" seems a bit cumbersome as we only need to know whether to skip or not, we don't need a special way of distinguishing "skip this commit" from "this commit is good" and "this commit is bad"

But in short, bisect_auto_next was returning just after checkout It seemed. So after checkout, running the script seemed sensible. But I look at it as a normal git user. So you checkout, test your commit, skip to the next one if applicable.


I'll think of your two comments, and see if I can address them as you regain your concentration :p

But seeing that these are your main concerns, I'm more confident I'm not completly on the wrong path here.
