Unable to git bisect

[mcollina]

I'm trying to do a git bisect, but I'm unable to compile a commit because of a problem with snapshots:

/home/matteo/repositories/node-fork/out/Release/obj.target/v8_snapshot/geni/embedded.cc:5:10: fatal error: src/snapshot/macros.h: No such file or directory

I and others have run into this in the past, I think a hard reset via git clean -fdx did the trick (but obviously costs some time).

[mcollina]

That fixes it. Should we document it somewhere?

[joyeecheung]

Looks like a duplicate of #28675

BTW I think I ran into this month(s?) ago on V8 master, I remember a fresh clone of V8 and clearing my ccache did the trick back then, so it probably comes from the upstream.

EDIT: um, no, I think I had another issue

[mcollina]

Yes it is. Closing and thanks for the help!

For those who face the same issue: running git clean -fdx is not always enoguh. The full sequence of commands that need to be run in order to remove all cached build files are:

rm .gitignore
git clean -fdx
git stash
git stash drop

Then build and continue bisecting.
