Is there a way to prevent our pex-controlled lockfiles from locking deps for platforms we don't support (ie. i686, aarch64). We exclusively use x86_64, but I'm not seeing options that would let us restrict to that arch

I don’t think there is at the moment. I believe this would require plumbing

--platforms

and/or

--complete-platforms

through to

pex lock create

here

Probably not worth it then. Just a minor performance and manual audit (of the lock file) nice-to-have

This would require Pex work. Pex already supports

--platforms

and

--complete-platforms

when creating locks as Benjy guessed, but, when

--style=universal

, which is true for all Pants use of Pex lock files, those platforms are just checked as a post-processing step after the lock is created. If they cannot resolve from the lock, the locking operation fails as a whole. With `--style={strict,sources}`then the platforms work as Benjy guessed and restrict to exactly those platforms passed in.
