... whoops, looks like CI wasn't enough here. buildbots show issues that look related. :) WASM doesn't have threading, the previously logic presumably properly skipped the test there. |
Sorry, something went wrong.

test_concurrent_futureswas previously skipped on platforms that don't support multiprocessing. Android and iOS don't support multiprocessing, but they do support threading, so this PR gives them test coverage of the threading-related parts ofconcurrent.futures. A couple of more focused skips were added to exclude the process-related tests.I also had to remove an unused import of
_multiprocessingfrommultiprocessing.queues. This allowsmultiprocessing.queuesto be imported on platforms that don't support multiprocessing, as long as the code doesn't actually create a queue.Other places which are helped by this change include:
test___all__, which no longer needs a multiprocessing-specific workaround.logging.config, which importsmultiprocessing.queueonly to do anisinstancecheck. No code changes were required here.
