In#130148, there was discussion of what would be required to make
redirect_stdoutthread-aware.#130148 (comment) proposed adding aper_thread: bool = Falseargument. This PR implements that argument.To support interleaving
per_thread=Falseandper_thread=True, this PR uses a slightly more complicated design involving walking up the stack of context managers to find the first one applicable to its thread.As an example motivating usage, making
doctestthread-safe becomes a ~one line change with this PR:https://github.com/python/cpython/compare/main...Liam-DeVoe:cpython:redirect-stdout-doctest?expand=1.I think there's been previous discussion of whether this should live in CPython or be proven out in another project first. I don't know exactly where people have fallen on this. I opened a previous version of this code againstQuansight-Labs/pytest-run-parallel#167, but after discussion with@ngoldbaum it was unclear to us that pytest-run-parallel is the right place for this to live, rather than the standard library.
