1dd6d95 closes bpo-42030: Remove legacy AIX dynload support (GH-22717) 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. 16 October 2020, 18:03:28 UTC

This change also prepares the conversion of the UCD_Type static type to a heap type. 15 October 2020, 14:22:19 UTC

b67cbbd Minor clarification (GH-22708) 15 October 2020, 06:41:55 UTC
2d2af32 bpo-41894: Fix UnicodeDecodeError while loading native module (GH-22466) 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.

7992579 bpo-40422: Move _Py_closerange to fileutils.c (GH-22680) This API is relatively lightweight and organizationally, given that it's used by multiple modules, it makes sense to move it to fileutils.

64eb259 bpo-40422: Move _Py_*_SUPPRESS_IPH bits into _Py_closerange (GH-22672) This suppression is no longer needed in os_closerange_impl, as it just invokes the internal _Py_closerange implementation. On the other hand, consumers of _Py_closerange may not have any other reason to suppress invalid parameter issues, so narrow the scope to here. 12 October 2020, 23:53:16 UTC

1800c60 bpo-40423: Optimization: use close_range(2) if available (GH-22651) 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 11 October 2020, 20:18:53 UTC
c230fde bpo-40422: create a common _Py_closerange API (GH-19754) 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 11 October 2020, 18:54:11 UTC

aecf036 bpo-41306: Allow scale value to not be rounded (GH-21715) 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`).

35f041d bpo-41376: Fix the documentation of `site.getusersitepackages()` (GH-21602) `site.getusersitepackages()` returns the location of the user-specific site-packages directory even when the user-specific site-packages is disabled. ``` $ python -s -m site sys.path = [ '/home/user/conda/lib/python37.zip', '/home/user/conda/lib/python3.7', '/home/user/conda/lib/python3.7/lib-dynload', '/home/user/conda/lib/python3.7/site-packages', ] USER_BASE: '/home/user/.local' (exists) USER_SITE: '/home/user/.local/lib/python3.7/site-packages' (doesn't exist) ENABLE_USER_SITE: False ``` It was not practical to prevent the function from returning None if user-specific site-packages are disabled, since there are other uses of the function which are relying on this behaviour (e.g. `python -m site`). 08 October 2020, 06:37:46 UTC

044a104 bpo-38605: Make 'from __future__ import annotations' the default (GH-20434) 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). 06 October 2020, 20:03:02 UTC

This likely isn't exploitable because unicodedata.lookup(seqname) is called before self.checkletter(seqname, None) - thus any string which isn't a valid unicode character name wouldn't ever reach the checkletter method.
