* Minor improvement to the namedtuple implementation (GH-20741)Raymond Hettinger2020-06-081-1/+4
| | | | | * Cleaner way to build the arg list with a trailing comma when required * Fix appearance of __new__ in help()
* bpo-40910: Export Py_GetArgcArgv() function (GH-20721)Victor Stinner2020-06-081-3/+31
| | | | | | | | | | | | Export explicitly the Py_GetArgcArgv() function to the C API and document the function. Previously, it was exported implicitly which no longer works since Python is built with -fvisibility=hidden. * Add PyConfig._orig_argv member. * Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice. * PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now _PyConfig_Write() responsibility. * _PyConfig_Write() result type becomes PyStatus instead of void. * Write an unit test on Py_GetArgcArgv().

* bpo-39791 native hooks for importlib.resources.files (GH-20576)Jason R. Coombs2020-06-076-191/+112

* bpo-40767: Allow pure Wayland to get default XDG web browser (GH-20382)Jeremy Attali2020-06-031-1/+1
| | | | | | | Would be nice to backport to python 3.7+. I don't think it's worth the hassle to backport this all the way down to 3.10. But I'll let the maintainers decide. This is hard to test because the test setup already includes this [environment variable](https://github.com/python/cpython/blob/master/Lib/test/pythoninfo.py#L292) Let me know if something doesn't match the PR guidelines. This is my first PR in the python source code.
* bpo-40826: Add _PyOS_InterruptOccurred(tstate) function (GH-20599)Victor Stinner2020-06-031-6/+16
| | | | | | | | | | | | my_fgets() now calls _PyOS_InterruptOccurred(tstate) to check for pending signals, rather calling PyOS_InterruptOccurred(). my_fgets() is called with the GIL released, whereas PyOS_InterruptOccurred() must be called with the GIL held. test_repl: use text=True and avoid SuppressCrashReport in test_multiline_string_parsing(). Fix my_fgets() on Windows: fgets(fp) does crash if fileno(fp) is closed.

* bpo-17005: Move topological sort functionality to its own module (GH-20558)Pablo Galindo2020-06-014-515/+490
| | | | | | The topological sort functionality that was introduced initially in the functools module has been moved to a new graphlib module to better accommodate the new tools and keep the original scope of the functools module.

* Fix asyncio.to_thread() documented return type (GH-20547)Kyle Stanley2020-05-311-1/+1
| | | | | When I wrote the documentation for `asyncio.to_thread()`, I mistakenly assumed that `return await loop.run_in_executor(...)` within an async def function would return a Future. In reality, it returns a coroutine. This likely won't affect typical usage of `asyncio.to_thread()`, but it's important for the documentation to be correct here. In general, we also tend to avoid returning futures from high-level APIs in asyncio.
* bpo-39885: Make IDLE context menu cut and copy work again (GH-18951)Terry Jan Reedy2020-05-293-16/+50
| | | | Leave selection when right click within. This exception to clearing selections when right-clicking was omitted from the previous commit, 4ca060d. I did not realize that this completely disabled the context menu entries, and I should have merged a minimal fix immediately. An automated test should follow.
* bpo-29882: Add an efficient popcount method for integers (#771)Niklas Fiekas2020-05-292-1/+13
| | | | | | | | | | | | | | | | | | | | | | | * bpo-29882: Add an efficient popcount method for integers * Update 'sign bit' and versionadded in docs * Add entry to whatsnew document * Doc: use positive example, mention population count * Minor cleanups of the core code * Move popcount_digit closer to where it's used * Use z instead of self after conversion * Add 'absolute value' and 'population count' to docstring * Fix clinic error about missing summary line * Ensure popcount_digit is portable with 64-bit ints Co-authored-by: Mark Dickinson <dickinsm@gmail.com>

* bpo-39040: Fix parsing of email mime headers with whitespace between ↵Abhilash Raj2020-05-282-0/+28
| | | | | | | | | | | | | | | encoded-words. (gh-17620) * bpo-39040: Fix parsing of email headers with encoded-words inside a quoted string. It is fairly common to find malformed mime headers (especially content-disposition headers) where the parameter values, instead of being encoded to RFC standards, are "encoded" by doing RFC 2047 "encoded word" encoding, and then enclosing the whole thing in quotes. The processing of these malformed headers was incorrectly leaving the spaces between encoded words in the decoded text (whitespace between adjacent encoded words is supposed to be stripped on decoding). This changeset fixes the encoded word processing inside quoted strings (bare-quoted-string) to do correct RFC 2047 decoding by stripping that whitespace.

* bpo-30064: Fix unstable asyncio "racing" socket tests (GH-20485)Victor Stinner2020-05-281-0/+4
| | | | | Skip new "racing" socket tests which fail randomly until someone fix them, to ease analysis of buildbot failures (skip tests which are known to be broken/unstable).
* Revert "Upgrade bundled versions of pip & setuptools (#16782)" (GH-20484)Victor Stinner2020-05-284-6/+6
| | | This reverts commit feb0846c3a28b05b4cfbc6ab34c764957f3eff55.
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-284-15/+11
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-40275: test.support imports subprocess lazily (GH-20471)Victor Stinner2020-05-281-3/+11
| | | | | | | | | | | test.support module now imports the platform and subprocess modules lazily to reduce the number of modules imported by "import test.support". With this change, the threading module is no longer imported indirectly by "import test.support". Use sys.version rather than platform.machine() to detect the Windows ARM32 buildbot.
* bpo-40275: test.support.check_impl_detail() uses sys.implementation (GH-20468)Victor Stinner2020-05-281-1/+1
| | | | | check_impl_detail() of test.support now uses sys.implementation.name, instead of platform.python_implementation().lower(). This change prepares test.support to import the platform module lazily.
* bpo-40795: ctypes calls unraisablehook with an exception (GH-20452)Victor Stinner2020-05-283-27/+44
| | | | | | If ctypes fails to convert the result of a callback or if a ctypes callback function raises an exception, sys.unraisablehook is now called with an exception set. Previously, the error was logged into stderr by PyErr_Print().

* bpo-40791: Use CRYPTO_memcmp() for compare_digest (#20456)Christian Heimes2020-05-272-36/+55
| | | | | | | | hashlib.compare_digest uses OpenSSL's CRYPTO_memcmp() function when OpenSSL is available. Note: The _operator module is a builtin module. I don't want to add libcrypto dependency to libpython. Therefore I duplicated the wrapper function and added a copy to _hashopenssl.c.
