* gh-109723: Disable Py_BUILD_CORE in _testcapi (#109727)Victor Stinner2023-09-228-101/+114
| | | | | | | | | | | | | | | | | | Make sure that the internal C API is not tested by mistake by _testcapi. Undefine Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE macros in Modules/_testcapi/parts.h: move code from _testcapimodule.c. heaptype_relative.c and vectorcall_limited.c are using the limited C API which is incompatible with the internal C API. Move test_long_numbits() from _testcapi to _testinternalcapi since it uses the internal C API "pycore_long.h". Fix Modules/_testcapi/pyatomic.c: don't include Python.h directly, just include _testcapi/parts.h. Ajust "make check-c-globals" for these changes.

* gh-109582: test_fork_signal_handling should wait for event (#109605)Davide Rizzo2023-09-211-2/+11
| | | | | | Sometimes the child_handled event was missing because either the child quits before it gets a chance to handle the signal, or the parent asserts before the event notification is delivered via IPC. Synchronize explicitly to avoid this.

* gh-109613: _pystat_fromstructstat() checks for exceptions (#109618)Victor Stinner2023-09-212-49/+76
| | | | | | | | | | | | | Fix os.stat() and os.DirEntry.stat(): check for exceptions. Previously, on Python built in debug mode, these functions could trigger a fatal Python error (and abort the process) when a function succeeded with an exception set. _pystat_fromstructstat() now exits immediately if an exception is raised, rather only checking for exceptions at the end. It fix following fatal error in fill_time(): Fatal Python error: _Py_CheckSlotResult: Slot * of type int succeeded with an exception set

| | | | | | | | | | | | | SubprocessProtocol process_exited() method can be called before pipe_data_received() and pipe_connection_lost() methods. Document it and adapt the test for that. Revert commit 282edd7b2a74c4dfe1bfe3c5b1d30f9c21d554d6. _child_watcher_callback() calls immediately _process_exited(): don't add an additional delay with call_soon(). The reverted change didn't make _process_exited() more determistic: it can still be called before pipe_connection_lost() for example. Co-authored-by: Davide Rizzo <sorcio@gmail.com>

* gh-109543: Remove unnecessary hasattr check (#109544)Jelle Zijlstra2023-09-203-2/+14

* gh-103053: Skip test_freeze_simple_script() on PGO build (#109591)Victor Stinner2023-09-205-10/+36
| | | | | | | | | | Skip test_freeze_simple_script() of test_tools.test_freeze if Python is built with "./configure --enable-optimizations", which means with Profile Guided Optimization (PGO): it just makes the test too slow. The freeze tool is tested by many other CIs with other (faster) compiler flags. test.pythoninfo now gets also get_build_info() of test.libregrtests.utils.
* gh-90108: Disable LTO on _freeze_module and _testembed (#109581)Victor Stinner2023-09-201-2/+2
| | | | | | LTO optimization is nice to make Python faster, but _freeze_module and _testembed performance is not important. Using LTO to build these two programs make a whole Python build way slower, especially combined with a sanitizer (like ASAN).
* gh-109109: Expose retrieving certificate chains in SSL module (#109113)Mateusz Nowak2023-09-203-4/+63
| | | | | Adds APIs to get the TLS certificate chains, verified or full unverified, from SSLSocket and SSLObject. Co-authored-by: Gregory P. Smith [Google LLC] <greg@krypto.org>
* gh-109033: Return filename with os.utime errors (#109034)Ronan Pigott2023-09-193-7/+11
| | | | | | | The filename was previously intentionally omitted from exception because "it might confuse the user". Uncaught exceptions are not generally a replacement for user-facing error messages, so obscuring this information only has the effect of making the programmer's life more difficult.
* gh-76785: Use Pending Calls When Releasing Cross-Interpreter Data (gh-109556)Eric Snow2023-09-197-67/+98
| | | This fixes some crashes in the _xxinterpchannels module, due to a race between interpreters.
* gh-109580: Skip test_perf_profiler on ASAN build (#109584)Victor Stinner2023-09-192-1/+8
| | | | Skip test_perf_profiler if Python is built with ASAN, MSAN or UBSAN sanitizer. Python does crash randomly in this test on such build.
* gh-108724: Fix _PySemaphore compile error on WASM (gh-109583)Sam Gross2023-09-191-1/+2
| | | Some WASM platforms have POSIX semaphores, but not sem_timedwait.
* gh-108724: Add PyMutex and _PyParkingLot APIs (gh-109344)Sam Gross2023-09-1929-21/+1665
| | | | | | | | | | | | | | | | | | | | | | | | | | PyMutex is a one byte lock with fast, inlineable lock and unlock functions for the common uncontended case. The design is based on WebKit's WTF::Lock. PyMutex is built using the _PyParkingLot APIs, which provides a cross-platform futex-like API (based on WebKit's WTF::ParkingLot). This internal API will be used for building other synchronization primitives used to implement PEP 703, such as one-time initialization and events. This also includes tests and a mini benchmark in Tools/lockbench/lockbench.py to compare with the existing PyThread_type_lock. Uncontended acquisition + release: * Linux (x86-64): PyMutex: 11 ns, PyThread_type_lock: 44 ns * macOS (arm64): PyMutex: 13 ns, PyThread_type_lock: 18 ns * Windows (x86-64): PyMutex: 13 ns, PyThread_type_lock: 38 ns PR Overview: The primary purpose of this PR is to implement PyMutex, but there are a number of support pieces (described below). * PyMutex: A 1-byte lock that doesn't require memory allocation to initialize and is generally faster than the existing PyThread_type_lock. The API is internal only for now. * _PyParking_Lot: A futex-like API based on the API of the same name in WebKit. Used to implement PyMutex. * _PyRawMutex: A word sized lock used to implement _PyParking_Lot. * PyEvent: A one time event. This was used a bunch in the "nogil" fork and is useful for testing the PyMutex implementation, so I've included it as part of the PR. * pycore_llist.h: Defines common operations on doubly-linked list. Not strictly necessary (could do the list operations manually), but they come up frequently in the "nogil" fork.

* gh-109496: Skip test_capi.test_decref_freed_object() on ASAN (#109573)Victor Stinner2023-09-191-0/+2
| | | | Skip test_decref_freed_object() of test_capi.test_misc if Python is built with ASAN, MSAN or UBSAN sanitizers.
