* bpo-42208: Pass tstate to _PyGC_CollectNoFail() (GH-23038)Victor Stinner2020-10-305-34/+25
| | | | | | | | | | | | Move private _PyGC_CollectNoFail() to the internal C API. Remove the private _PyGC_CollectIfEnabled() which was just an alias to the public PyGC_Collect() function since Python 3.8. Rename functions: * collect() => gc_collect_main() * collect_with_callback() => gc_collect_with_callback() * collect_generations() => gc_collect_generations()

* bpo-42160: tempfile: Reduce overhead of pid check. (GH-22997)Eric W2020-10-303-14/+13
| | | | The _RandomSequence class in tempfile used to check the current pid every time its rng property was used. This commit replaces this code with `os.register_at_fork` to reduce the overhead.

* bpo-42161: Remove private _PyLong_Zero and _PyLong_One (GH-23003)Victor Stinner2020-10-273-23/+0
| | | | | Use PyLong_FromLong(0) and PyLong_FromLong(1) of the public C API instead. For Python internals, _PyLong_GetZero() and _PyLong_GetOne() of pycore_long.h can be used.
* bpo-42099: Fix reference to ob_type in unionobject.c and ceval (GH-22829)Neil Schemenauer2020-10-272-2/+2

* bpo-42157: Rename unicodedata.ucnhash_CAPI (GH-22994)Victor Stinner2020-10-275-5/+13
| | | | | | | Removed the unicodedata.ucnhash_CAPI attribute which was an internal PyCapsule object. The related private _PyUnicode_Name_CAPI structure was moved to the internal C API. Rename unicodedata.ucnhash_CAPI as unicodedata._ucnhash_CAPI.

* bpo-30681: Support invalid date format or value in email Date header (GH-22090)Georges Toth2020-10-2710-5/+59
| | | | | | | | | | | | | | | | | | | | I am re-submitting an older PR which was abandoned but is still relevant, #10783 by @timb07. The issue being solved () is still relevant. The original PR #10783 was closed as the final request changes were not applied and since abandoned. In this new PR I have re-used the original patch plus applied both comments from the review, by @maxking and @pganssle. For reference, here is the original PR description: In email.utils.parsedate_to_datetime(), a failure to parse the date, or invalid date components (such as hour outside 0..23) raises an exception. Document this behaviour, and add tests to test_email/test_utils.py to confirm this behaviour. In email.headerregistry.DateHeader.parse(), check when parsedate_to_datetime() raises an exception and add a new defect InvalidDateDefect; preserve the invalid value as the string value of the header, but set the datetime attribute to None. Add tests to test_email/test_headerregistry.py to confirm this behaviour; also added test to test_email/test_inversion.py to confirm emails with such defective date headers round trip successfully. This pull request incorporates feedback gratefully received from @bitdancer, @brettcannon, @Mariatta and @warsaw, and replaces the earlier PR #2254. Automerge-Triggered-By: GH:warsaw
* bpo-42161: Add _PyLong_GetZero() and _PyLong_GetOne() (GH-22993)Victor Stinner2020-10-266-25/+67
| | | | | | Add _PyLong_GetZero() and _PyLong_GetOne() functions and a new internal pycore_long.h header file. Python cannot be built without small integer singletons anymore.
* bpo-42123: Run the parser two times and only enable invalid rules on the ↵Lysandros Nikolaou2020-10-266-50/+70
| | | | | | | | | | second run (GH-22111) * Implement running the parser a second time for the errors messages The first parser run is only responsible for detecting whether there is a `SyntaxError` or not. If there isn't the AST gets returned. Otherwise, the parser is run a second time with all the `invalid_*` rules enabled so that all the customized error messages get produced.
* bpo-42157: Convert unicodedata.UCD to heap type (GH-22991)Victor Stinner2020-10-263-84/+56
| | | | | | | Convert the unicodedata extension module to the multiphase initialization API (PEP 489) and convert the unicodedata.UCD static type to a heap type. Co-Authored-By: Mohamed Koubaa <koubaa.m@gmail.com>
* bpo-42157: unicodedata avoids references to UCD_Type (GH-22990)Victor Stinner2020-10-267-136/+126
| | | | | | | | | | * UCD_Check() uses PyModule_Check() * Simplify the internal _PyUnicode_Name_CAPI structure: * Remove size and state members * Remove state and self parameters of getcode() and getname() functions * Remove global_module_state

* bpo-1635741: _PyUnicode_Name_CAPI moves to internal C API (GH-22713)Victor Stinner2020-10-2611-49/+74
| | | | | | | | | | The private _PyUnicode_Name_CAPI structure of the PyCapsule API unicodedata.ucnhash_CAPI moves to the internal C API. Moreover, the structure gets a new state member which must be passed to the getcode() and getname() functions. * Move Include/ucnhash.h to Include/internal/pycore_ucnhash.h * unicodedata module is now built with Py_BUILD_CORE_MODULE. * unicodedata: move hashAPI variable into unicodedata_module_state.
* bpo-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)Serhiy Storchaka2020-10-2611-163/+135
| | | | | | | If PyDict_GetItemWithError is only used to check whether the key is in dict, it is better to use PyDict_Contains instead. And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can replace the combination.
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-2617-137/+254
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.

* bpo-42146: Fix memory leak in subprocess.Popen() in case of uid/gid overflow ↵Alexey Izbyshev2020-10-263-2/+17
| | | | | | | | | | | (GH-22966) Fix memory leak in subprocess.Popen() in case of uid/gid overflow Also add a test that would catch this leak with `--huntrleaks`. Alas, the test for `extra_groups` also exposes an inconsistency in our error reporting: we use a custom ValueError for `extra_groups`, but propagate OverflowError for `user` and `group`.

* bpo-35823: Allow setsid() after vfork() on Linux. (GH-22945)Gregory P. Smith2020-10-241-2/+3
| | | | | | | | | | | It should just be a syscall updating a couple of fields in the kernel side process info. Confirming, in glibc is appears to be a shim for the setsid syscall (based on not finding any code implementing anything special for it) and in uclibc (*much* easier to read) it is clearly just a setsid syscall shim. A breadcrumb _suggesting_ that it is not allowed on Darwin/macOS comes from a commit in emacs: https://lists.gnu.org/archive/html/bug-gnu-emacs/2017-04/msg00297.html but I don't have a way to verify if that is true or not. As we are not supporting vfork on macOS today I just left a note in a comment.
