* bpo-46850: Remove _PyEval_CallTracing() function (GH-32019)Victor Stinner2022-03-211-0/+3
| | | | Remove the private undocumented function _PyEval_CallTracing() from the C API. Call the public sys.call_tracing() function instead.
* bpo-46850: Remove _PyEval_GetCoroutineOriginTrackingDepth() (GH-32018)Victor Stinner2022-03-211-0/+4
| | | | | | | | | | | | | | | Remove the private undocumented function _PyEval_GetCoroutineOriginTrackingDepth() from the C API.

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.

| | | | | | | | | | | Remove the following private undocumented functions from the C API: * _PyEval_GetAsyncGenFirstiter() * _PyEval_GetAsyncGenFinalizer() * _PyEval_SetAsyncGenFirstiter() * _PyEval_SetAsyncGenFinalizer() Call the public sys.get_asyncgen_hooks() and sys.set_asyncgen_hooks() functions instead.
* bpo-38256: Fix binascii.crc32() when inputs are 4+GiB (GH-32000)Gregory P. Smith2022-03-201-0/+14
| | | | | | | When compiled with `USE_ZLIB_CRC32` defined (`configure` sets this on POSIX systems), `binascii.crc32(...)` failed to compute the correct value when the input data was >= 4GiB. Because the zlib crc32 API is limited to a 32-bit length. This lines it up with the `zlib.crc32(...)` implementation that doesn't have that flaw. **Performance:** This also adopts the same GIL releasing for larger inputs logic that `zlib.crc32` has, and causes the Windows build to always use zlib's crc32 instead of our slow C code as zlib is a required build dependency on Windows.
* bpo-47015: Update test_os from asyncore to asyncio (GH-31876)Oleg Iarygin2022-03-201-0/+2
|
* bpo-42369: Fix thread safety of zipfile._SharedFile.tell (GH-26974)Kevin Mehall2022-03-201-0/+1
| | | | | | | | | | | The `_SharedFile` tracks its own virtual position into the file as `self._pos` and updates it after reading or seeking. `tell()` should return this position instead of calling into the underlying file object, since if multiple `_SharedFile` instances are being used concurrently on the same file, another one may have moved the real file position. Additionally, calling into the underlying `tell` may expose thread safety issues in the underlying file object because it was called without taking the lock.
* bpo-47040: improve document of checksum functions (gh-31955)Ma Lin2022-03-191-0/+2
| | | | | | | Clarifies a versionchanged note on crc32 & adler32 docs that the workaround is only needed for Python 2 and earlier. Also cleans up an unnecessary intermediate variable in the implementation. Authored-By: Ma Lin / animalize Co-authored-by: Gregory P. Smith <greg@krypto.org>
* bpo-46382 dataclass(slots=True) now takes inherited slots into account ↵Arie Bovenberg2022-03-191-0/+2
| | | | | (GH-31980) Do not include any members in __slots__ that are already in a base class's __slots__.
