What's the deal with https://www.pantsbuild.org/v2.16/docs/reference-subprocess-environment#env_vars? It seems like it's only used in Python, but the name sounds generic?

it comes from Pants 1.25 before we had any best practices etc https://github.com/pantsbuild/pants/issues/14809

Oh wow! Code Archeology

hah yeah I wish we fixed it as part of 2.0. At the very beginning, when it was added, it was basically adding whatever it took to get Twitter and Pants using remote execution for the

test

goal (my project). Before that, v2 was I think only used for

list

. So we used a lot of hacks

Yeah, probably it should be used everywhere? It's often used for generic things like LC_CTYPE and LANG

I'm trying to use

PATH

and

LD_LIBRARY_PATH

So it should probably be used as described on the tin! I'd consider it a bug that it is not

Yeah, probably it should be used everywhere? It’s often used for generic things like LC_CTYPE and LANG

while a subsystem for “evironment variables which are used absolutely everywhere” would probably be useful, i don’t think that

PATH

and

LD_LIBRARY_PATH

are likely candidates for that subsystem (whereas LC_CTYPE and LANG probably are). a proliferation of purpose-driven / “scoped” subsystems makes more sense to me, although “path-like” variables are strange, because they are almost always additive.
