* bpo-40854: Allow overriding sys.platlibdir via PYTHONPLATLIBDIR env-var ↵Victor Stinner2020-06-082-0/+17
| | | | | | | (GH-20605) (GH-20725) (cherry picked from commit 8f023a2f664f902a3d0b7a6f64d63afc0d1c15ae) Co-authored-by: Sandro Mani <manisandro@gmail.com>
* bpo-40910: Export Py_GetArgcArgv() function (GH-20721) (GH-20723)Victor Stinner2020-06-081-0/+9
| | | | | | | | | | | | | | Export explicitly the Py_GetArgcArgv() function to the C API and document the function. Previously, it was exported implicitly which no longer works since Python is built with -fvisibility=hidden. * Add PyConfig._orig_argv member. * Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice. * PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now _PyConfig_Write() responsibility. * _PyConfig_Write() result type becomes PyStatus instead of void. * Write an unit test on Py_GetArgcArgv().

* [3.9] bpo-40630: Add tracemalloc.reset_peak (GH-20102) (GH-20545)Huon Wilson2020-06-012-0/+65
| | | | | | | | | | | * bpo-40630: Add tracemalloc.reset_peak (GH-20102, cherrypick 8b62644) The reset_peak function sets the peak memory size to the current size, representing a resetting of that metric. This allows for recording the peak of specific sections of code, ignoring other code that may have had a higher peak (since the most recent `tracemalloc.start()` or tracemalloc.clear_traces()` call). * Adjust docs to point to 3.9

* Fix asyncio.to_thread() documented return type (GH-20547)Miss Islington (bot)2020-05-311-2/+1
| | | | | | | | When I wrote the documentation for `asyncio.to_thread()`, I mistakenly assumed that `return await loop.run_in_executor(...)` within an async def function would return a Future. In reality, it returns a coroutine. This likely won't affect typical usage of `asyncio.to_thread()`, but it's important for the documentation to be correct here. In general, we also tend to avoid returning futures from high-level APIs in asyncio.

| | | | | | | | | | | Try to make the meaning of platlibdir clear. The previous wording could be misinterpreted to suggest that it will be used to find all shared libraries on the system, and not just Python extensions. Furthermore, it was unclear whether it affects third-party (site-packages) extensions or not. The new wording tries to make its dual purpose clear, and provide the additional example of extensions in site-packages.
