* bpo-43693 Get rid of CO_NOFREE -- it's unused (GH-26839)Guido van Rossum2021-06-2310-260/+239
| | | | | | All uses of this flag are either setting it or in doc or tests for it. So we should be able to get rid of it completely.
* bpo-42862: Strip stale sqlite3 cache ignores from c-analyzer (GH-26876)Erlend Egeberg Aasland2021-06-231-5/+0

* bpo-39947: Remove old private trashcan C API functions (GH-26869)Victor Stinner2021-06-235-78/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove 4 C API private trashcan functions which were only kept for the backward compatibility of the stable ABI with Python 3.8 and older, since the trashcan API was not usable with the limited C API on Python 3.8 and older. The trashcan API was excluded from the limited C API in Python 3.9. Removed functions: * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * _PyTrash_thread_deposit_object() * _PyTrash_thread_destroy_chain() The trashcan C API was never usable with the limited C API, since old trashcan macros accessed directly PyThreadState members like "_tstate->trash_delete_nesting", whereas the PyThreadState structure is opaque in the limited C API. Exclude also the PyTrash_UNWIND_LEVEL constant from the C API. The trashcan C API was modified in Python 3.9 by commit 38965ec5411da60d312b59be281f3510d58e0cf1 and in Python 3.10 by commit ed1a5a5baca8f61e9a99c5be3adc16b1801514fe to hide implementation details.
* bpo-43770: Cleanup PyModuleDef_Init() (GH-26879)Victor Stinner2021-06-231-2/+1
| | | | | PyModuleDef_Init() no longer tries to make PyModule_Type type: it's already done by _PyTypes_Init() at Python startup. Replace PyType_Ready() call with an assertion.
* bpo-42064: Move `sqlite3` exceptions to global state, part 1 of 2 (GH-26745)Erlend Egeberg Aasland2021-06-238-49/+67
| | | Also adds a test to verify the (borrowed) exceptions in `sqlite3.Connection`.
* bpo-44441: _PyImport_Fini2() resets PyImport_Inittab (GH-26874)Victor Stinner2021-06-236-8/+85
| | | | | Py_RunMain() now resets PyImport_Inittab to its initial value at exit. It must be possible to call PyImport_AppendInittab() or PyImport_ExtendInittab() at each Python initialization.

* bpo-40528: Implement a metadata system for ASDL Generator (GH-20193)Batuhan Taskaya2021-06-221-24/+75
| | | | | | | | ASDL Generator was lack of proper annotation related to generated module. This patch implements a MetadataVisitor that produces a metadata object to pass to other visitors that are visiting that same module. For the inital patch, it dynamically retrieves int sequences (like cmpop), that was previously hardcoded. It offers an interface that is easy to extend.
* bpo-41621: Document defaultdict's default_factory parameter (GH-21945)Dennis Sweeney2021-06-223-3/+4

| | | | | | | correctly (GH-26764) No longer use len() to get the length of the input data. For some buffer protocol objects, the length obtained by using len() is wrong.
* bpo-44458: Ensure BUFFER_BLOCK_SIZE symbol is statically allocated. (GH-26808)Russell Keith-Magee2021-06-222-1/+2

* bpo-44287: asyncio test_popen() uses longer timeout (GH-26832)Victor Stinner2021-06-212-1/+6
| | | | | | | | Fix asyncio test_popen() of test_windows_utils by using a longer timeout. Use military grade battle-tested test.support.SHORT_TIMEOUT timeout rather than a hardcoded timeout of 10 seconds: it's 30 seconds by default, but it is made longer on slow buildbots. WaitForMultipleObjects() timeout argument is in milliseconds.
* bpo-13814: Explain why generators are not context managers (GH-26835)Terry Jan Reedy2021-06-212-0/+10

* bpo-43693: Turn localspluskinds into an object (GH-26749)Guido van Rossum2021-06-2114-5394/+5454
| | | Managing it as a bare pointer to malloc'ed bytes is just too awkward in a few places.

* bpo-44434: Don't call PyThread_exit_thread() explicitly (GH-26758)Victor Stinner2021-06-212-1/+7
| | | | | | | | | | | | | | | | | | | | | | _thread.start_new_thread() no longer calls PyThread_exit_thread() explicitly at the thread exit, the call was redundant. On Linux with the glibc, pthread_cancel() loads dynamically the libgcc_s.so.1 library. dlopen() can fail if there is no more available file descriptor to open the file. In this case, the process aborts with the error message: "libgcc_s.so.1 must be installed for pthread_cancel to work" pthread_cancel() unwinds back to the thread's wrapping function that calls the thread entry point. The unwind function is dynamically loaded from the libgcc_s library since it is tightly coupled to the C compiler (GCC). The unwinder depends on DWARF, the compiler generates DWARF, so the unwinder belongs to the compiler. Thanks Florian Weimer and Carlos O'Donell for their help on investigating this issue.
* bpo-44466: Faulthandler now detects the GC (GH-26823)Victor Stinner2021-06-215-14/+70
| | | | The faulthandler module now detects if a fatal error occurs during a garbage collector collection (only if all_threads is true).
* bpo-44337: Improve LOAD_ATTR specialization (GH-26759)Mark Shannon2021-06-213-72/+179

* bpo-43945: [Enum] reduce scope of new format() behavior (GH-26752)Ethan Furman2021-06-185-29/+225
| | | | | | | | | | | | | | | | | | | | | * [Enum] reduce scope of new format behavior Instead of treating all Enums the same for format(), only user mixed-in enums will be affected. In other words, IntEnum and IntFlag will not be changing the format() behavior, due to the requirement that they be drop-in replacements of existing integer constants. If a user creates their own integer-based enum, then the new behavior will apply: class Grades(int, Enum): A = 5 B = 4 C = 3 D = 2 F = 0 Now: format(Grades.B) -> DeprecationWarning and '4' 3.12: -> no warning, and 'B'
