* [3.8] bpo-41302: Support system libmpdec 2.5 for Python 3.8 (GH-21488)Felix Yan2020-07-151-0/+7
| | | | | | | Define UNUSED only when mpdecimal.h doesn't define it. This would support building with system libmpdec 2.5 while retaining compatibility with system libmpdec 2.4 or the vendored copy. Tested to build fine with either system libmpdec or the vendored one.

* bpo-41247: asyncio.set_running_loop() cache running loop holder (#21406)Tony Solomonik2020-07-091-3/+6
| | | | | | | The running loop holder cache variable was always set to NULL when calling set_running_loop. Now set_running_loop saves the newly created running loop holder in the cache variable for faster access in get_running_loop.

| | | | | | | | | If ctypes fails to convert the result of a callback or if a ctypes callback function raises an exception, sys.unraisablehook is now called with an exception set. Previously, the error was logged into stderr by PyErr_Print(). (cherry picked from commit 10228bad0452d94e66c964b625a0b61befa08e59) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-13097: ctypes: limit callback to 1024 arguments (GH-19914)Miss Islington (bot)2020-05-271-0/+15
| | | | | | | | | | | | | ctypes now raises an ArgumentError when a callback is invoked with more than 1024 arguments. The ctypes module allocates arguments on the stack in ctypes_callproc() using alloca(), which is problematic when large numbers of arguments are passed. Instead of a stack overflow, this commit raises an ArgumentError if more than 1024 parameters are passed.
