raaaandom thought. but: a way to get partial-but-bulletproof caching for pex requirements in v2 would be to execute a resolve per library, rather than only for binaries.
and to feed the caches from output snapshots into the next resolve.
having said that
...we should probably just re-enable the pex cache, and trust it to be concurrency safe.

pex resolve is about to get a lot faster vis improvements in upstream pip. this is how i have been approaching the resolve time problem for ipex
w
that is definitely excellent.
this comment was more to do with the fact that we currently disable pex's cache in v2

if everything is an ipex and uses the faster resolve method, we don’t have to worry about that at all
w
about not having a cache of the fetched requirements?
that would still mean you fetched everything every time for tests
a
the ipex resolve would use the normal pex cache
w
which is disabled, heh.
a
it decouples this concern from pants
...not in the ipex. when an ipex runs, it uses normal pex settings. that was my point
w
i think we might be talking about different usecases... i'm talking about for tests, mostly.
a
i think we should be using this approach everywhere. i haven’t written this up specifically anywhere else yet, though
(that’s part of my plan this week though. can resume this in a doc)
