* bpo-42197: Don't create `f_locals` dictionary unless we actually need it. ↵Mark Shannon2022-03-257-10/+46
| | | | | | | | | | | (GH-32055) * `PyFrame_FastToLocalsWithError` and `PyFrame_LocalsToFast` are no longer called during profile and tracing. (Contributed by Fabio Zadrozny) * Make accesses to a frame's `f_locals` safe from C code, not relying on calls to `PyFrame_FastToLocals` or `PyFrame_LocalsToFast`. * Document new `PyFrame_GetLocals` C-API function.
* Add an issue template config for the migration (GH-32101)Ezio Melotti2022-03-241-0/+5

* bpo-46480: rephrase typing.assert_type docs (GH-32069)Shantanu2022-03-242-2/+2
| | | | | | | | | The goal here is to reduce potential confusion between `assert_type(val, type)` and `assert isinstance(val, typ)`. The former is meant to ask a type checker to confirm a fact, the latter is meant to tell a type checker a fact. The behaviour of the latter more closely resembles what I'd expect from the prior phrasing of "assert [something] to the type checker".

* bpo-46712: Do not Regen Deep-Frozen Modules before Generating Global Objects ↵Eric Snow2022-03-232-12/+36
| | | | | | | | | (gh-32061) We have to run "make regen-deepfreeze" before running Tools/scripts/generate-global-objects.py; otherwise we will miss any changes to global objects in deep-frozen modules (which aren't committed in the repo). However, building $(PYTHON_FOR_FREEZE) fails if one of its source files had a global object (e.g. via _Py_ID(...)) added or removed, without generate-global-objects.py running first. So "make regen-global-objects" would sometimes fail. We solve this by running generate-global-objects.py before *and* after "make regen-deepfreeze". To speed things up and cut down on noise, we also avoid updating the global objects files if there are no changes to them. https://bugs.python.org/issue46712
* bpo-46541: Add a Comment About When to Use _Py_DECLARE_STR(). (gh-32063)Eric Snow2022-03-231-0/+10
| | | | | In a gh-32003 comment, I realized it wasn't very clear how _Py_DECLARE_STR() should be used. This changes adds a comment to clarify. https://bugs.python.org/issue46541
* bpo-46829: Deprecate passing a message into Future.cancel() and ↵Andrew Svetlov2022-03-239-17/+106
| | | | | Task.cancel() (GH-31840) After a long deliberation we ended up feeling that the message argument for Future.cancel(), added in 3.9, was a bad idea, so we're deprecating it in 3.11 and plan to remove it in 3.13.

* [doc] configparser: avoid inline comments. (GH-31247)Julien Palard2022-03-231-2/+4

* bpo-40280: Skip socket, fork, subprocess tests on Emscripten (GH-31986)Christian Heimes2022-03-2252-23/+238
| | | | | | | | | | | - Add requires_fork and requires_subprocess to more tests - Skip extension import tests if dlopen is not available - Don't assume that _testcapi is a shared extension - Skip a lot of socket tests that don't work on Emscripten - Skip mmap tests, mmap emulation is incomplete - venv does not work yet - Cannot get libc from executable The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).

* bpo-44336: Prevent tests hanging on child process handles on Windows (GH-26578)Jeremy Kloth2022-03-222-185/+117
| | | | | Replace the child process `typeperf.exe` with a daemon thread that reads the performance counters directly. This prevents the issues that arise from inherited handles in grandchild processes (see issue37531 for discussion). We only use the load tracker when running tests in multiprocess mode. This prevents inadvertent interactions with tests expecting a single threaded environment. Displaying load is really only helpful for buildbots running in multiprocess mode anyway.
* bpo-47061: document module deprecations due to PEP 594 (GH-31984)Brett Cannon2022-03-2127-22/+97

| | | | | | | | | | | | | | | | | | | * Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place. * Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches * _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms. * _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches * _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup * _Py_Quicken is renamed to _PyCode_Quicken * _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview). * Do not emit unused nonzero opargs anymore in the compiler.

| | | | | | | | | | | | | | | Remove the private undocumented function _PyEval_GetCoroutineOriginTrackingDepth() from the C API. Call the public sys.get_coroutine_origin_tracking_depth() function instead. Change the internal function _PyEval_SetCoroutineOriginTrackingDepth(): * Remove the 'tstate' parameter; * Add return value and raises an exception if depth is negative; * No longer export the function: call the public sys.set_coroutine_origin_tracking_depth() function instead.
