* bpo-33824, bpo-32030: Fix pymain_read_conf() (GH-7712)Victor Stinner2018-06-161-0/+1
| | | | | | Fix "LC_ALL=C python3.7 -V": reset properly the command line parser when the encoding changes after reading the Python configuration. Fix pymain_read_conf(): use memset(0) to reset properly cmdline.
* bpo-29456: Fix bugs in unicodedata.normalize: u1176, u11a7 and u11c3 (GH-1958)Wonsup Yoon2018-06-151-3/+7
| | | | | Hangul composition check boundaries are wrong for the second character ([0x1161, 0x1176) instead of [0x1161, 0x1176]) and third character ((0x11A7, 0x11C3) instead of [0x11A7, 0x11C3]).
* bpo-33615: Re-enable subinterpreter tests. (#7552)Eric Snow2018-06-131-37/+45
| | | All the subinterpreter tests were disabled in gh-7513. This commit re-enables them, but leaves one bad test disabled. The test is partly causing problems because it makes assumptions about the availability of a high-level interpreters module (see PEP 554). So I'm disabling the test until such a high-level module is available.

* bpo-31432: Revert unrelated code changes to _ssl.c and test_ssl (GH-7650)Ned Deily2018-06-111-2/+2

* bpo-31432: Clarify ssl CERT_NONE/OPTIONAL/REQUIRED docs. (GH-3530)Christian Heimes2018-06-111-2/+2
| | | | | | | | | The documentation for CERT_NONE, CERT_OPTIONAL, and CERT_REQUIRED were misleading and partly wrong. It fails to explain that OpenSSL behaves differently in client and server mode. Also OpenSSL does validate the cert chain everytime. With SSL_VERIFY_NONE a validation error is not fatal in client mode and does not request a client cert in server mode. Also discourage people from using CERT_OPTIONAL in client mode.
* bpo-33812: Corrected astimezone for naive datetimes. (GH-7578)Alexander Belopolsky2018-06-101-0/+11
| | | | | | | | | | | | | | | | | | | | A datetime object d is aware if d.tzinfo is not None and d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None, or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None, d is naive. This commit ensures that instances with non-None d.tzinfo, but d.tzinfo.utcoffset(d) returning None are treated as naive. In addition, C acceleration code will raise TypeError if d.tzinfo.utcoffset(d) returns an object with the type other than timedelta. * Updated the documentation. Assume that the term "naive" is defined elsewhere and remove the not entirely correct clarification. Thanks, Tim.
* Remove unneeded PyErr_Occurred() check in os_lseek_impl() (GH-7557)Zackery Spytz2018-06-101-3/+0
| | | | | This call became unneeded after the posix module was converted to the Argument Clinic in 2f93635d342a500053e97c9c7c30f1eaf11fc3ac and should have been removed as part of that change.

* bpo-33781: audioop: enhance rounding double as int (GH-7447)Victor Stinner2018-06-061-11/+17
| | | | | | Move the floor() call into fbound() to call floor() on a double rather than an int. The change should enhance the rounding. Document also (int)double rounding mode.
* bpo-33767: Fix improper use of SystemError by mmap.mmap objects (GH-7381)Zackery Spytz2018-06-051-20/+2
| | | | Raise TypeError instead of SystemError for unsupported operations.
* bpo-33615: Re-enable a subinterpreter test. (gh-7251)Eric Snow2018-06-011-0/+1
| | | For bpo-32604 I added extra subinterpreter-related tests (see #6914), which caused a few buildbots to crash. This patch fixes the crash by ensuring that refcounts in channels are handled properly.
* bpo-33724: Use the right format code for int64_t in subinterpreters code. ↵Eric Snow2018-06-011-32/+33

* bpo-33706: Fix pymain_parse_cmdline_impl() (GH-7283)Victor Stinner2018-05-311-1/+1
| | | | | | | | | | Fix a crash in Python initialization when parsing the command line options. Fix memcpy() size parameter: previously, we read one wchar_t after the end of _PyOS_optarg. Moreover, don't copy the trailingg NUL character: we write it manually anyway. Thanks Christoph Gohlke for the bug report and the fix!
* bpo-33677: Fix signatures of tp_clear handlers for AST and deque. (GH-7196)Serhiy Storchaka2018-05-311-3/+4

* bpo-33622: Add checks for exceptions leaks in the garbage collector. (GH-7126)Serhiy Storchaka2018-05-291-4/+23
| | | | | * Failure in adding to gc.garbage is no longer fatal. * An exception in tp_clear() no longer lead to crash (though tp_clear() should not leave exceptions).
* bpo-32610: Fix asyncio.all_tasks() to return only pending tasks. (GH-7174)Yury Selivanov2018-05-281-2/+2

* bpo-32493: Fix uuid.uuid1() on FreeBSD. (GH-7099)Serhiy Storchaka2018-05-251-1/+8
| | | Use uuid_enc_be() if available to encode UUID to bytes as big endian.
* bpo-33622: Fix issues with handling errors in the GC. (GH-7078)Serhiy Storchaka2018-05-241-8/+11
| | | | | | | * Fixed a leak when the GC fails to add an object with __del__ into the gc.garbage list. * PyGC_Collect() can now be called when an exception is set and preserves it. * Fixed an undefined behavior with comparing a dead pointer with NULL.
* bpo-33583: Add note in PyObject_GC_Resize() doc (GH-7021)INADA Naoki2018-05-211-0/+1

* bpo-33584: Fix several minor bugs in asyncio. (GH-7003)Serhiy Storchaka2018-05-201-15/+21
| | | | | | | | | | | | Fix the following bugs in the C implementation: * get_future_loop() silenced all exceptions raised when look up the get_loop attribute, not just an AttributeError. * enter_task() silenced all exceptions raised when look up the current task, not just a KeyError. * repr() was called for a borrowed link in enter_task() and task_step_impl(). * str() was used instead of repr() in formatting one error message (in Python implementation too). * There where few reference leaks in error cases.
* Fix typo in error message when decoding PYTHONPATH. (GH-6981)Carl Meyer2018-05-191-1/+1

* bpo-32604: Implement force-closing channels. (gh-6937)Eric Snow2018-05-171-21/+136
| | | This will make it easier to clean up channels (e.g. when used in tests).
* bpo-13631: Fix the order of initialization for readline libedit on macOS. ↵Zvezdan Petkovic2018-05-171-1/+3
| | | | | | (GH-6915) The editline emulation needs to be initialized *after* the name is defined. This fixes the long open issue.
* Replace _PyGC_REFS macros with higher level macros (GH-6852)INADA Naoki2018-05-171-2/+1
| | | | Only gcmodule.c uses _PyGC_REFS* macros now. This makes easy to read GC code.
* bpo-32604: Improve subinterpreter tests. (#6914)Eric Snow2018-05-161-73/+177
| | | Add more tests for subinterpreters. This patch also fixes a few small defects in the channel implementation.

* bpo-27645, sqlite: Fix integer overflow on sleep (#6594)Victor Stinner2018-04-301-4/+20
| | | | | | | | | Use the _PyTime_t type and round away from zero (ROUND_UP, _PyTime_ROUND_TIMEOUT) the sleep duration, when converting a Python object to seconds and then to milliseconds. Raise an OverflowError in case of overflow. Previously the (int)double conversion rounded towards zero (ROUND_DOWN).
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-2925-220/+216
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-33383: Fix crash in get() of the dbm.ndbm database object. (#6630)Serhiy Storchaka2018-04-292-5/+5

* bpo-33329: Fix multiprocessing regression on newer glibcs (GH-6575)Antoine Pitrou2018-04-231-6/+8
| | | | | | | Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some reserved signal numbers between 1 and NSIG. The `range(1, NSIG)` idiom is commonly used to select all signals for blocking with `pthread_sigmask`. So we ignore the sigaddset() return value until we expose sigfillset() to provide a better idiom.
* bpo-32232: by default, Setup modules are no longer built with ↵xdegaye2018-04-212-20/+20
| | | | | | | | | -DPy_BUILD_CORE (GH-6489) Setup modules are no longer built with -DPy_BUILD_CORE by default, as using that flag may now require including additional internal-only header files. Instead, only the modules that specifically need it use that setting.
* bpo-33308: Fix a crash in the parser module when convert an ST object. (#6519)Serhiy Storchaka2018-04-191-3/+3
| | | | Converting with line_info=False and col_info=True crashed before.

* bpo-23403: Bump pickle.DEFAULT_PROTOCOL to 4 (#6355)Łukasz Langa2018-04-032-11/+17
| | | This makes performance better and produces shorter pickles. This change is backwards compatible up to the oldest currently supported version of Python (3.4).
