Sam Gross	289af86122	gh-111569: Fix critical sections test on WebAssembly (GH-111897) This adds a macro `Py_CAN_START_THREADS` that corresponds to the Python function `test.support.threading_helper.can_start_thread()`. WASI and some Emscripten builds do not have a working pthread implementation. This macro is used to guard the critical sections C API tests that require a working threads implementation.	2023-11-09 15:37:11 -08:00
Sam Gross	31c90d5838	gh-111569: Implement Python critical section API (gh-111571) Critical sections are helpers to replace the global interpreter lock with finer grained locking. They provide similar guarantees to the GIL and avoid the deadlock risk that plain locking involves. Critical sections are implicitly ended whenever the GIL would be released. They are resumed when the GIL would be acquired. Nested critical sections behave as if the sections were interleaved.	2023-11-08 15:39:29 -07:00

gh-111569: Fix critical sections test on WebAssembly (GH-111897)

This adds a macro `Py_CAN_START_THREADS` that corresponds to the Python
function `test.support.threading_helper.can_start_thread()`. WASI and
some Emscripten builds do not have a working pthread implementation.

This macro is used to guard the critical sections C API tests that
require a working threads implementation.

gh-111569: Implement Python critical section API (gh-111571)

Critical sections are helpers to replace the global interpreter lock
with finer grained locking.  They provide similar guarantees to the GIL
and avoid the deadlock risk that plain locking involves.  Critical
sections are implicitly ended whenever the GIL would be released.  They
are resumed when the GIL would be acquired.  Nested critical sections
behave as if the sections were interleaved.
