From: "Alex Hoffman" <s...@gal.ro>
isn't that spelt `--ancestry-path` ?
(--ancestry-path has it's own issues such as needing
an --first-parent-show
option, but that's possibly a by the by)
Indeed it is spelled `--ancestry-path`. And interestingly enough you
may use it multiple times with the wanted effect in our case (e.g when
the user has multiple good commit and a single bad commit before
running the bisect itself).
Also it is `--first-parent` (not `--first-parent-show`),
My spelling was deliberate ;-)
If you use the currently coded --first-parent with a properly relevant
commit for --ancestry-path then you get nothing. The purpose of
ancestry-path is to find the ancestry chain that deviates from being a
first-parent traversal [1], but the first-parent want to hold the walk to
just the first parent chain - a contradiction.
Adding the -show at the end is my attempt to indicate that it is for the
second aspect, that of selecting which commits to show/use.
I had an initial discussion back at [2], but failed then too.
but I do not understand why do we need this
option? What kind of issues does `--ancestry-path` have?
Best regards,
VG
