* bpo-41845: Move PyObject_GenericGetDict() back into the limited API (GH22646)Zackery Spytz2020-10-191-0/+2
| | | | It was moved out of the limited API in 7d95e4072169911b228c9e42367afb5f17fd3db0. This change re-enables it from 3.10, to avoid generating invalid extension modules for earlier versions.

* closes bpo-42030: Remove legacy AIX dynload support (GH-22717)Kevin Adler2020-10-161-0/+3
| | | | | | | | Since c19c5a6, AIX builds have defaulted to using dynload_shlib over dynload_aix when dlopen is available. This function has been available since AIX 4.3, which went out of support in 2003, the same year the previously referenced commit was made. It has been nearly 20 years since a version of AIX has been supported which has not used dynload_shlib so there's no reason to keep this legacy code around.

* bpo-41894: Fix UnicodeDecodeError while loading native module (GH-22466)Kevin Adler2020-10-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running in a non-UTF-8 locale, if an error occurs while importing a native Python module (say because a dependent share library is missing), the error message string returned may contain non-ASCII code points causing a UnicodeDecodeError. PyUnicode_DecodeFSDefault is used for buffers which may contain filesystem paths. For consistency with os.strerror(), PyUnicode_DecodeLocale is used for buffers which contain system error messages. While the shortname parameter is always encoded in ASCII according to PEP 489, it is left decoded using PyUnicode_FromString to minimize the changes and since it should not affect the decoding (albeit _potentially_ slower). In dynload_hpux, since the error buffer contains a message generated from a static ASCII string and the module filesystem path, PyUnicode_DecodeFSDefault is used instead of PyUnicode_DecodeLocale as is used elsewhere. * bpo-41894: Fix bugs in dynload error msg handling For both dynload_aix and dynload_hpux, properly handle the possibility that decoding strings may return NULL and when such an error happens, properly decrement any previously decoded strings and return early. In addition, in dynload_aix, ensure that we pass the decoded string *object* pathname_ob to PyErr_SetImportError instead of the original pathname buffer.

* bpo-40423: Optimization: use close_range(2) if available (GH-22651)Kyle Evans2020-10-111-0/+3
| | | | | | | close_range(2) should be preferred at all times if it's available, otherwise we'll use closefrom(2) if available with a fallback to fdwalk(3) or plain old loop over fd range in order of most efficient to least. [note that this version does check for ENOSYS, but currently ignores all other errors] Automerge-Triggered-By: @pablogsal
* bpo-40422: create a common _Py_closerange API (GH-19754)Kyle Evans2020-10-111-0/+1
| | | | | | | Such an API can be used both for os.closerange and subprocess. For the latter, this yields potential improvement for platforms that have fdwalk but wouldn't have used it there. This will prove even more beneficial later for platforms that have close_range(2), as the new API will prefer that over all else if it's available. The new API is structured to look more like close_range(2), closing from [start, end] rather than the [low, high) of os.closerange(). Automerge-Triggered-By: @gpshead
* bpo-41993: Fix possible issues in remove_module() (GH-22631)Serhiy Storchaka2020-10-111-0/+2

* bpo-41306: Allow scale value to not be rounded (GH-21715)E-Paine2020-10-081-0/+1
| | | | | | | This fixes the test failure with Tk 6.8.10 which is caused by changes to how Tk rounds the `from`, `to` and `tickinterval` arguments. This PR uses `noconv` if the patchlevel is greater than or equal to 8.6.10 (credit to Serhiy for this idea as it is much simpler than what I previously proposed). Going into more detail for those who want it, the Tk change was made in [commit 591f68c](https://github.com/tcltk/tk/commit/591f68cb382525b72664c6fecaab87742b6cc87a) and means that the arguments listed above are rounded relative to the value of `from`. However, when rounding the `from` argument ([line 623](https://github.com/tcltk/tk/blob/591f68cb382525b72664c6fecaab87742b6cc87a/generic/tkScale.c#L623)), it is rounded relative to itself (i.e. rounding `0`) and therefore the assigned value for `from` is always what is given (no matter what values of `from` and `resolution`).

* bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)Batuhan Taskaya2020-10-061-0/+3
| | | | | The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions. For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).

| | | | | | | | | | | Enable recursion checks which were disabled when get __bases__ of non-type objects in issubclass() and isinstance() and when intern strings. It fixes a stack overflow when getting __bases__ leads to infinite recursion. Originally recursion checks was disabled for PyDict_GetItem() which silences all errors including the one raised in case of detected recursion and can return incorrect result. But now the code uses PyDict_GetItemWithError() and PyDict_SetDefault() instead.
