Idea: Differentiate between Task-local and "spawn-propagated" Task-local

7

Task-local data is not propagated across calls to `spawn`, which aligns with the behavior of Thread-local data. But since Tasks are "lighter" than threads, a common pattern is to effectively...

Directory canonicalization does not require non-empty names

2

Hey folks! The definition of "canonical" for a `Directory` does not currently (https://github.com/bazelbuild/remote-apis/blob/f54876595da9f2c2d66c98c318d00b60fd64900b/build/bazel/remote/execution/v2/remote_execution.proto#L634-L653) require that the names of children are non-empty, but in practice this seems like a useful constraint....

Vendored `pip` in `pex` not located inside created virtualenv on macOS

Hitting PEX cache(s) is not as fast as expected

4

This is potentially related to #1093, but I'm filing it as a separate issue to avoid muddying the water if it isn't. On `example-python` at 72890abf9426c9744d9e2537f898fb6c2bb17216 (using Pants `2.0.0` and...

PEX_VERBOSE env var is not propagated to pip subprocesses, but -vvv is

1

Passing `-vvv` to `pex` results in `-v` being passed to `pip` due to this section: https://github.com/pantsbuild/pex/blob/a7d98116daedcacda4716ebc9ca831303f24b71f/pex/pip.py#L73-L79 But for some reason, passing `PEX_VERBOSE=9` does not propagate to `pip`. Tested with `2.1.6`...
