where in the code base are 
InteractiveProcess
processes actually spawned?
h
<http://interface.rs|interface.rs>
session_run_interactive_process
f
and would there be an issue if I added append_only_caches support to InteractiveProcess for when run_in_workspace=False ?
(which is where some coursier files are, context is for scala repl)
w
…alllthooough. the JVM to spawn would still be in a named cache.
so yea.
h
also I think I'm really really close to finishing PyO3. Stu helped me this morning to figure out my main blocker, how to port the 
with_scheduler
context managers 
<http://interface.rs|interface.rs>
is almost green, and then just have to finish 
<http://intrinsics.rs|intrinsics.rs>
and 
<http://nodes.rs|nodes.rs>
So might be worth waiting before dabbling with that code
f
I’m already dabbling in the InteractiveProcess code.
just a WIP PR. it’ll need to be split any way.
current issue is that the working directory is set to a temp dir under the system tmp dir, but the files are materialized to a tmpdir under .pants.d
w
f
so two tmp dirs, which is weird
(I had to thread run_in_workspace through from ReplRequest)
w
is the initial inference PR landable? that would let others experiment.
but i guess we’re not doing thirdparty inference yet huh
f
wrong thread?
and already landed …
w
oh, whoops. thanks.
yea, there wasn’t a thread for it.
are you starting thirdparty, or should i after lunch?
f
you should given what I replied with on toolchain slack

https://github.com/pantsbuild/pants/pull/12986 may be of interest for third-party artifact Scala support. That is WIP 
scala_artifact
support.
w
thanks, will do!
