* Issue #26146: remove useless codeVictor Stinner2016-01-261-7/+0
| | | | | | | | obj2ast_constant() code is baesd on obj2ast_object() which has a special case for Py_None. But in practice, we don't need to have a special case for constants. Issue noticed by Joseph Jevnik on a review.
* Fix a refleak in validate_constant()Victor Stinner2016-01-261-0/+2
| | | | Issue #26146.
* Add ast.ConstantVictor Stinner2016-01-255-14/+181
| | | | | | | | | | | | | | | | | | | | | Issue #26146: Add a new kind of AST node: ast.Constant. It can be used by external AST optimizers, but the compiler does not emit directly such node. An optimizer can replace the following AST nodes with ast.Constant: * ast.NameConstant: None, False, True * ast.Num: int, float, complex * ast.Str: str * ast.Bytes: bytes * ast.Tuple if items are constants too: tuple * frozenset Update code to accept ast.Constant instead of ast.Num and/or ast.Str: * compiler * docstrings * ast.literal_eval() * Tools/parser/unparse.py
* Issue #26146: marshal.loads() now uses the empty frozenset singletonVictor Stinner2016-01-231-29/+40

* Issue #18018: Raise an ImportError if a relative import is attemptedBrett Cannon2016-01-231-3/+8
| | | | | | | | with no known parent package. Previously SystemError was raised if the parent package didn't exist (e.g., __package__ was set to ''). Thanks to Florent Xicluna and Yongzhi Pan for reporting the issue.
* Issue #25791: Warn when __package__ != __spec__.parent.Brett Cannon2016-01-222-93/+121
| | | | | | | | | In a previous change, __spec__.parent was prioritized over __package__. That is a backwards-compatibility break, but we do eventually want __spec__ to be the ground truth for module details. So this change reverts the change in semantics and instead raises an ImportWarning when __package__ != __spec__.parent to give people time to adjust to using spec objects.
* Use Py_uintptr_t for atomic pointersVictor Stinner2016-01-222-27/+28
| | | | | | | | Issue #26161: Use Py_uintptr_t instead of void* for atomic pointers in pyatomic.h. Use atomic_uintptr_t when <stdatomic.h> is used. Using void* causes compilation warnings depending on which implementation of atomic types is used.
* code_richcompare() now uses the constants typesVictor Stinner2016-01-221-48/+10
| | | | | | | | | Issue #25843: When compiling code, don't merge constants if they are equal but have a different types. For example, "f1, f2 = lambda: 1, lambda: 1.0" is now correctly compiled to two different functions: f1() returns 1 (int) and f2() returns 1.0 (int), even if 1 and 1.0 are equal. Add a new _PyCode_ConstantKey() private function.
* co_lnotab supports negative line number deltaVictor Stinner2016-01-203-135/+152
| | | | | | | | | | | | | | | | | | | | | Issue #26107: The format of the co_lnotab attribute of code objects changes to support negative line number delta. Changes: * assemble_lnotab(): if line number delta is less than -128 or greater than 127, emit multiple (offset_delta, lineno_delta) in co_lnotab * update functions decoding co_lnotab to use signed 8-bit integers - dis.findlinestarts() - PyCode_Addr2Line() - _PyCode_CheckLineNumber() - frame_setlineno() * update lnotab_notes.txt * increase importlib MAGIC_NUMBER to 3361 * document the change in What's New in Python 3.6 * cleanup also PyCode_Optimize() to use better variable names

| * Add _PyThreadState_UncheckedGet()Victor Stinner2016-01-203-21/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which gets the current thread state, but don't call Py_FatalError() if it is NULL. Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h

| | | | | | | | | | | | | | | | not defined for a relative import. This is the start of work to try and clean up import semantics to rely more on a module's spec than on the myriad attributes that get set on a module. Thanks to Rose Ames for the patch.
