* bpo-36347: stop using RESTRICTED constants (GH-12684)Jeroen Demeyer2020-02-183-10/+8
| | | | | | | | The constants `RESTRICTED` and `PY_WRITE_RESTRICTED` no longer have a meaning in Python 3. Therefore, CPython should not use them. CC @matrixise https://bugs.python.org/issue36347

* bpo-39546: argparse: Honor allow_abbrev=False for specified prefix_chars ↵Kyle Meyer2020-02-184-28/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | (GH-18337) When `allow_abbrev` was first added, disabling the abbreviation of long options broke the grouping of short flags ([bpo-26967](https://bugs.python.org/issue26967)). As a fix, b1e4d1b603 (contained in v3.8) ignores `allow_abbrev=False` for a given argument string if the string does _not_ start with "--" (i.e. it doesn't look like a long option). This fix, however, doesn't take into account that long options can start with alternative characters specified via `prefix_chars`, introducing a regression: `allow_abbrev=False` has no effect on long options that start with an alternative prefix character. The most minimal fix would be to replace the "starts with --" check with a "starts with two prefix_chars characters". But `_get_option_tuples` already distinguishes between long and short options, so let's instead piggyback off of that check by moving the `allow_abbrev` condition into `_get_option_tuples`. https://bugs.python.org/issue39546

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | failure (GH-17670) As reported initially by @rad-pat in #6084, the following script causes a deadlock. ``` from concurrent.futures import ProcessPoolExecutor class ObjectWithPickleError(): """Triggers a RuntimeError when sending job to the workers""" def __reduce__(self): raise RuntimeError() if __name__ == "__main__": e = ProcessPoolExecutor() f = e.submit(id, ObjectWithPickleError()) e.shutdown(wait=False) f.result() # Deadlock on get ``` This is caused by the fact that the main process is closing communication channels that might be necessary to the `queue_management_thread` later. To avoid this, this PR let the `queue_management_thread` manage all the closing. https://bugs.python.org/issue39104 Automerge-Triggered-By: @pitrou

* bpo-39606: allow closing async generators that are already closed (GH-18475)Nathaniel J. Smith2020-02-133-6/+41
| | | | | | | | | | | | | | The fix for [bpo-39386](https://bugs.python.org/issue39386) attempted to make it so you couldn't reuse a agen.aclose() coroutine object. It accidentally also prevented you from calling aclose() at all on an async generator that was already closed or exhausted. This commit fixes it so we're only blocking the actually illegal cases, while allowing the legal cases. The new tests failed before this patch. Also confirmed that this fixes the test failures we were seeing in Trio with Python dev builds: https://github.com/python-trio/trio/pull/1396 https://bugs.python.org/issue39606

* closes bpo-39605: Fix some casts to not cast away const. (GH-18453)Andy Lester2020-02-1211-39/+39
| | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts

* bpo-38374: Remove weakref.ReferenceError from docs (GH-18452)Roger Hurwitz2020-02-112-9/+0
| | | | | | | | | | Reflecting changes to the code, removed weakref.ReferenceError from weakref.rst and exceptions.rst. Issue submitter provided evidence that the `weakref.ReferenceError` alias for `ReferenceError` was removed from the code in 2007. Working with @gvanrossum at PyCascades CPython sprint we looked at the code and confirmed that `weakref.ReferenceError` was no longer in `weakref.py`. Based on that analysis I removed references `weakref.ReferenceError` from the two documents where it was still being referenced: `weakref.rst` and `exceptions.rst`. https://bugs.python.org/issue38374
