* bpo-45296: Fix exit/quit message on Windows (GH-28577)Terry Jan Reedy2021-09-281-0/+2
| | | | IDLE recognizes Ctrl-D, as on other systems, instead of Ctrl-Z.
* bpo-1596321: Fix threading._shutdown() for the main thread (GH-28549)Victor Stinner2021-09-271-0/+3
| | | | | Fix the threading._shutdown() function when the threading module was imported first from a thread different than the main thread: no longer log an error at Python exit.
* bpo-45274: Fix Thread._wait_for_tstate_lock() race condition (GH-28532)Victor Stinner2021-09-271-0/+5
| | | | | | Fix a race condition in the Thread.join() method of the threading module. If the function is interrupted by a signal and the signal handler raises an exception, make sure that the thread remains in a consistent state to prevent a deadlock.
* bpo-45280: Add test for empty `NamedTuple` in `test_typing` (GH-28559)Nikita Sobolev2021-09-261-0/+1
| | | Co-authored-by: Dong-hee Na <donghee.na92@gmail.com>
* bpo-21302: Add nanosleep() implementation for time.sleep() in Unix (GH-28545)Victor Stinner2021-09-251-0/+1
| | | Co-authored-by: Livius <egyszeregy@freemail.hu>
* bpo-45166: fixes `get_type_hints` failure on `Final` (GH-28279)Nikita Sobolev2021-09-251-0/+2

* bpo-44019: Implement operator.call(). (GH-27888)Antony Lee2021-09-241-0/+2
| | | | | | Having `operator.call(obj, arg)` mean `type(obj).__call__(obj, arg)` is consistent with the other dunder operators. The semantics with `*args, **kwargs` then follow naturally from the single-arg semantics.
* bpo-20524: adds better error message for `.format()` (GH-28310)Nikita Sobolev2021-09-241-0/+3
| | | It now lists the bad format_spec and the type of the object.
* bpo-39359: [zipfile] add missing "pwd: expected bytes, got str" exception ↵Daniel Hillier2021-09-231-0/+1
| | | | (GH-18031)
* bpo-38415: Allow using @asynccontextmanager-made ctx managers as decorators ↵Jason Fried2021-09-231-0/+3
| | | | (GH-16667)
* bpo-39549: reprlib.Repr uses a “fillvalue” attribute (GH-18343)Alexander Böhn2021-09-221-0/+4
|
* bpo-45238: Fix unittest.IsolatedAsyncioTestCase.debug() (GH-28449)Serhiy Storchaka2021-09-221-0/+2
| | | | | | It runs now asynchronous methods and callbacks. If it fails, doCleanups() can be called for cleaning up.
* bpo-21302: time.sleep() uses waitable timer on Windows (GH-28483)Victor Stinner2021-09-221-0/+3
| | | | | | | | | | | | On Windows, time.sleep() now uses a waitable timer which has a resolution of 100 ns (10^-7 sec). Previously, it had a solution of 1 ms (10^-3 sec). * On Windows, time.sleep() now calls PyErr_CheckSignals() before resetting the SIGINT event. * Add _PyTime_As100Nanoseconds() function. * Complete and update time.sleep() documentation.

* bpo-45234: Fix FileNotFound exception raised instead of IsADirectoryError in ↵andrei kulakov2021-09-211-0/+3
| | | | | shutil.copyfile() (GH-28421) This was a regression from fixing BPO-43219.
* bpo-45061: Detect refcount bug on empty string singleton (GH-28504)Victor Stinner2021-09-211-2/+3
| | | | | | | Detect refcount bugs in C extensions when the empty Unicode string singleton is destroyed by mistake. * Move forward declarations to the top of unicodeobject.c. * Simplifiy unicode_is_singleton().

* bpo-45061: Detect refcount bug on empty tuple singleton (GH-28503)Victor Stinner2021-09-211-0/+4
| | | | | | Detect refcount bugs in C extensions when the empty tuple singleton is destroyed by mistake. Add the _Py_FatalRefcountErrorFunc() function.
* bpo-45209: fix `UserWarning: resource_tracker` in test_multiprocessing ↵Nikita Sobolev2021-09-211-0/+2
| | | | (GH-28377)

* bpo-45128: fixes `test_multiprocessing_fork` mysterious crash (GH-28387)Nikita Sobolev2021-09-191-0/+2
|
* bpo-30856: Update TestResult early, without buffering in _Outcome (GH-28180)Serhiy Storchaka2021-09-191-0/+6
| | | | | | | TestResult methods addFailure(), addError(), addSkip() and addSubTest() are now called immediately after raising an exception in test or finishing a subtest. Previously they were called only after finishing the test clean up.
* bpo-36674: Honour the skipping decorators in TestCase.debug() (GH-28446)Serhiy Storchaka2021-09-181-0/+2
| | | | | | | | unittest.TestCase.debug() raises now a SkipTest if the class or the test method are decorated with the skipping decorator. Previously it only raised a SkipTest if the test method was decorated with other decorator in addition to the skipping decorator, or if SkipTest was explicitly raised in the test or setup methods.
* bpo-45235: Fix argparse overrides namespace with subparser defaults (GH-28420)Adam Schwalm2021-09-181-0/+2
|
* bpo-45183: don't raise an exception when calling ↵Brett Cannon2021-09-171-0/+3
| | | | | zipimport.zipimporter.find_spec() when the zip file is missing and the internal cache has been reset (GH-28435) This can occur when the zip file gets deleted, you call zipimport.zipimporter.invalidate_cache(), and then try to use zipimport.zipimporter.find_spec() (i.e. you left the zip file path on sys.path).
* bpo-45116: Add the Py_ALWAYS_INLINE macro (GH-28390)Victor Stinner2021-09-171-0/+3
| | | | | Add the Py_ALWAYS_INLINE macro to ask the compiler to always inline a static inline function. The compiler can ignore it and decides to not inline the function.
* bpo-45162: Remove many old deprecated unittest features (GH-28268)Serhiy Storchaka2021-09-171-0/+6
| | | | | | | * "fail*" and "assert*" aliases of TestCase methods. * Broken from start TestCase method assertDictContainsSubset(). * Ignored TestLoader.loadTestsFromModule() parameter use_load_tests. * Old alias _TextTestResult of TextTestResult.
* bpo-45228: Fix stack buffer overflow in parsing J1939 address (GH-28404)Serhiy Storchaka2021-09-171-0/+1

* bpo-45188: Windows now regenerates frozen modules at the start of build ↵Steve Dower2021-09-151-0/+3
| | | | | | | instead of late (GH-28322) This will enable us to drop the frozen module header files from the repository. It does currently cause many source files to be built twice, which just takes more time. For whoever comes to fix this in the future, the files shared between freeze_module and pythoncore should be put into a static library that is consumed by both.
* bpo-45185: enables `TestEnumerations` in `test_ssl` (GH-28330)Nikita Sobolev2021-09-151-0/+1

* bpo-45020: Freeze some of the modules imported during startup. (gh-28335)Eric Snow2021-09-151-0/+4
| | | | | | | Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.) Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain. https://bugs.python.org/issue45020
* bpo-44786: Fix a warning in RE in c-analyzer (GH-28351)Serhiy Storchaka2021-09-151-0/+1
|
* bpo-45020: Add -X frozen_modules=[on|off] to explicitly control use of ↵Eric Snow2021-09-141-0/+3
| | | | | | | frozen modules. (gh-28320) Currently we freeze several modules into the runtime. For each of these modules it is essential to bootstrapping the runtime that they be frozen. Any other stdlib module that we later freeze into the runtime is not essential. We can just as well import from the .py file. This PR lets users explicitly choose which should be used, with the new "-X frozen_modules=[on|off]" CLI flag. The default is "off" for now. https://bugs.python.org/issue45020

* bpo-45195: Fix test_readline.test_nonascii() (GH-28329)Victor Stinner2021-09-141-0/+3
| | | | Fix test_readline.test_nonascii(): sometimes, the newline character is not written at the end, so don't expect it in the output.
* bpo-45156: Fixes inifite loop on unittest.mock.seal() (GH-28300)Nikita Sobolev2021-09-141-0/+2
