... 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_futures was 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 of concurrent.futures. A couple of more focused skips were added to exclude the process-related tests.
I also had to remove an unused import of _multiprocessing from multiprocessing.queues. This allows multiprocessing.queues to 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 imports multiprocessing.queue only to do an isinstance check. No code changes were required here.
