* bpo-31506: Improve the error message logic for class instantiation (GH-4740)Sanyam Khurana2017-12-101-0/+49
| | | | | | | | | | | | The error messages in `object.__new__` and `object.__init__` now aim to point the user more directly at the name of the class being instantiated in cases where they *haven't* been overridden (on the assumption that the actual problem is a missing `__new__` or `__init__` definition in the class body). When they *have* been overridden, the errors still report themselves as coming from object, on the assumption that the problem is with the call up to the base class in the method implementation, rather than with the way the constructor is being called.
* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-0913-99/+485
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

* bpo-32207: Improve tk event exception tracebacks in IDLE. (#4703)Terry Jan Reedy2017-12-041-5/+9
| | | | | | | | When tk event handling is driven by IDLE's run loop, a confusing and distracting queue.EMPTY traceback context is no longer added to tk event exception tracebacks. The traceback is now the same as when event handling is driven by user code. Patch based on a suggestion by Serhiy Storchaka.
* bpo-30928: Update idlelib/NEWS.txt to 2017 Dec 3. (#4701)Terry Jan Reedy2017-12-041-0/+16
| | | Patches are in 3.7.0a3 even if this update is not.
* bpo-25054, bpo-1647489: Added support of splitting on zerowidth patterns. ↵Serhiy Storchaka2017-12-042-14/+32
| | | | | | (#4471) Also fixed searching patterns that could match an empty string.
* Fix a regression in uuid added in bpo-32107. (#4677)Serhiy Storchaka2017-12-042-2/+5
| | | | | uuid.get_node() always must return a stable result. Also added a test for non-reproducibility of _random_getnode(). Original patch by Xavier de Gaye.
* bpo-27240 Rewrite the email header folding algorithm. (#3488)R. David Murray2017-12-035-563/+508
| | | | | | | | | | | | | | | | | | | | | The original algorithm tried to delegate the folding to the tokens so that those tokens whose folding rules differed could specify the differences. However, this resulted in a lot of duplicated code because most of the rules were the same. The new algorithm moves all folding logic into a set of functions external to the token classes, but puts the information about which tokens can be folded in which ways on the tokens...with the exception of mime-parameters, which are a special case (which was not even implemented in the old folder). This algorithm can still probably be improved and hopefully simplified somewhat. Note that some of the test expectations are changed. I believe the changes are toward more desirable and consistent behavior: in general when (re) folding a line the canonical version of the tokens is generated, rather than preserving errors or extra whitespace.
* bpo-32137: The repr of deeply nested dict now raises a RecursionError (#4570)Serhiy Storchaka2017-12-033-3/+19
| | | | | instead of crashing due to a stack overflow. This perhaps will fix similar problems in other extension types.
* bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675)Nick Coghlan2017-12-031-0/+45
| | | | | | | | Previously, CO_NOFREE was set in the compiler, which meant it could end up being set incorrectly when code objects were created directly. Setting it in the constructor based on freevars and cellvars ensures it is always accurate, regardless of how the code object is defined.
* Add a minimal unit test for Python/frozen.c. (#2995)Neil Schemenauer2017-12-021-0/+30
| | | | | | If the marshal or bytecode formats get changed, frozen.c needs to be updated as well. It can be easy to miss this step and not doing so can cause test_importlib to crash in mysterious ways. Add an explict unit test to make it easier to track down the problem.
* Fix asyncio.streams.FlowControlMixin docstring typo. (#4578)John Chen2017-12-011-1/+1

* bpo-28668: test.support.requires_multiprocessing_queue is removed (GH-4560)xdegaye2017-12-012-20/+7
| | | | Skip tests with test.support.import_module('multiprocessing.synchronize') instead when the semaphore implementation is broken or missing.
* bpo-10544: Deprecate "yield" in comprehensions and generator expressions. ↵Serhiy Storchaka2017-12-012-11/+36
| | | | | | | | | | | | | | (GH-4579) The current behaviour of yield expressions inside comprehensions and generator expressions is essentially an accident of implementation - it arises implicitly from the way the compiler handles yield expressions inside nested functions and generators. Since the current behaviour wasn't deliberately designed, and is inherently confusing, we're deprecating it, with no current plans to reintroduce it. Instead, our advice will be to use a named nested generator definition for cases where this behaviour is desired.
* bpo-32072: Fix issues with binary plists. (#4455)Serhiy Storchaka2017-11-302-36/+106
| | | | | | | * Fixed saving bytearrays. * Identical objects will be saved only once. * Equal references will be load as identical objects. * Added support for saving and loading recursive data structures.
* bpo-20891: Fix PyGILState_Ensure() (#4650)Victor Stinner2017-11-301-0/+10
| | | | | | | When PyGILState_Ensure() is called in a non-Python thread before PyEval_InitThreads(), only call PyEval_InitThreads() after calling PyThreadState_New() to fix a crash. Add an unit test in test_embed.

* bpo-32030: Rework memory allocators (#4625)Victor Stinner2017-11-295-23/+96
| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem
