[gentoo-user] Need some help with location of git clone when bisecting with 9999-ebuilds

I'm trying to track down a regression in app-emulation/wine-vanilla.
I've read https://wiki.gentoo.org/wiki/Bisecting_with_live_ebuilds and think I
understand how git bisect works and what it does, but three things are unclear
to me.
1) Where should I store the git clone of the repository and how do I tell
emerge to read the source files from there, when emerging the 9999 ebuild,
instead of downloading them from the Internet as usual?
2) Can I tell emerge not to clean the build directory between bisects so it
only recompiles the source files that actually changes between commits?
3) In the wiki's test-zfs.sh script, the EGIT_OVERRIDE_COMMIT variables are
poorly documented. What would the name of those be for app-emulation/wine-vanilla?

understanding git bisect should be enough to keep you going..

how about have a local clone of wine repository? and feed it to live ebuild
and you can do the bisect of this local repo..
$ git clone https://gitlab.winehq.org/wine/wine.git
$ pwd
/my/path/to/wine
# EGIT_OVERRIDE_REPO_WINE_WINE="file:///my/path/to/wine" \
emerge =app-emulation/wine-vanilla-9999
or I'd not personally bother to go this way

it would be great to have this feature, but I don't know..

EGIT_OVERRIDE_COMMIT_WINE_WINE? have you checked the emerge log? it's obvious

Thank you, Yixun.

Yes, I actually just ended up doing what git bisect does but manually for now.

My old machine takes 50 minutes to compile wine so it would've been great.
Guess it's time for me to upgrade. ;)

I noticed that by chance when I was looking in the log to check whether it
accepted the commit hash I fed it or not. But I ended up just using the
deprecated EGIT_COMMIT for this bisect and running it manually. Since most of
the time is spent compiling it wasn't that much work but I'll be sure to try a
more automated method next time now that I got the last pieces of the puzzle. :)
Just out of curiosity, what decides what the suffix to those EGIT_OVERRIDE_
variables will become? I was unable to find any info of those in the Gentoo
Development Guide, although I only looked at the description of the
git-r3.eclass and that might have been the wrong place.

doing ? Also, it works on some simpler builds to cd to the top of the
src tree and just issue a make.

In this particular case I'd like to also merge the compiled wine to my system

so I can do the test of the failing application in the same environment as I
normally run it in. But all is fine now and I got my questions answered so I
feel confident I'm better prepared now for any future bisects.
I'm doing my (hopefully) final bisect compile of wine as I write this and will
check the result tomorrow since it's way past bedtime for me now. :)

I have a dedicated ~/gitstuff for most of my stuff, but the obvious

other place is /usr/src (/wine).
