* PEP 553 built-in breakpoint() function (bpo-31353) (#3355)Barry Warsaw2017-10-051-0/+23
| | | Implement PEP 553, built-in breakpoint() with support from sys.breakpointhook(), along with documentation and tests. Closes bpo-31353
* bpo-31588: Validate return value of __prepare__() methods (GH-3764)Oren Milman2017-09-271-0/+7
| | | | | | | | | | Class execution requires that __prepare__() methods return a proper execution namespace. Check for that immediately after calling __prepare__(), rather than passing it through to the code execution machinery and potentially triggering SystemError (in debug builds) or a cryptic TypeError (in release builds). Patch by Oren Milman.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-141-1/+1
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-1/+1
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.

* bpo-30592: Fixed error messages for some builtins. (#1996)Serhiy Storchaka2017-06-081-3/+3
| | | | | Error messages when pass keyword arguments to some builtins that don't support keyword arguments contained double parenthesis: "()()". The regression was introduced by bpo-30534.

* | | Issue #29296: convert print() to METH_FASTCALLINADA Naoki2017-01-191-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Replace PyArg_ParseTupleAndKeywords() with _PyArg_ParseStackAndKeywords() which is more efficient to parse keywords, since it decodes only keywords (char*) from UTF-8 once, instead of decoding at each call. * METH_FASTCALL avoids the creation of a temporary tuple to pass positional arguments. Patch written by INADA Naoki, pushed by Victor Stinner.

| * | Issue #23722: improve __classcell__ compatibilityNick Coghlan2016-12-051-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling zero-argument super() in __init_subclass__ and __set_name__ involved moving __class__ initialisation to type.__new__. This requires cooperation from custom metaclasses to ensure that the new __classcell__ entry is passed along appropriately. The initial implementation of that change resulted in abruptly broken zero-argument super() support in metaclasses that didn't adhere to the new requirements (such as Django's metaclass for Model definitions). The updated approach adopted here instead emits a deprecation warning for those cases, and makes them work the same way they did in Python 3.5. This patch also improves the related class machinery documentation to cover these details and to include more reader-friendly cross-references and index entries.
* | | Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-4/+4
| | | | | | | | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* | | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

| | | | | | | | | | | | | | | | | | The __class__ cell used by zero-argument super() is now initialized from type.__new__ rather than __build_class__, so class methods relying on that will now work correctly when called from metaclass methods during class creation. Patch by Martin Teichmann.
