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.

Yeah, I found after Junio's hint :) What threw me off, as I wrote earlier, get_terms(). I wonder now, why is get_terms() implemented as it is, and should it not use the same functions? Or is it because terms is a multi-line file, whereas the others are all single line (I didn't look, though I see addline functions for the strbuf functions. Should this be refactored?

get_terms() wants to read the first line into `term_bad` and the second line into `term_good` so it makes sense that it uses two calls to `strbuf_getline()` to do that. It does not want to read the whole file into a single buffer as we do here.

So with the name, I started to think some more about it, and after playing with some names, I settled on 'bisect-post-checkout'. Things then sort of fell more into place. It is still a hook/commandline option, but it's a much smaller change (since we don't have any special code to check the exit code anymore) as we can (obviously) run `git bisect skip` instead of `exit 125` as well of course.

Does that mean you will be starting "git bisect skip" from the script run by the current "git bisect" process. I don't think calling git recursively like that is a good idea as you'll potentially end up with a bunch of "git bisect" processes all waiting for their post checkout script to finish running.

Best Wishes

Phillip
