* compiler: don't emit SyntaxWarning on const stmtVictor Stinner2016-02-081-22/+2
| | | | | Issue #26204: the compiler doesn't emit SyntaxWarning warnings anymore when constant statements are ignored.
* compiler now ignores constant statementsVictor Stinner2016-02-081-11/+30
| | | | | | | | | | | | | | | | | | | The compile ignores constant statements and emit a SyntaxWarning warning. Don't emit the warning for string statement because triple quoted string is a common syntax for multiline comments. Don't emit the warning on ellipis neither: 'def f(): ...' is a legit syntax for abstract functions. Changes: * test_ast: ignore SyntaxWarning when compiling test statements. Modify test_load_const() to use assignment expressions rather than constant expression. * test_code: add more kinds of constant statements, ignore SyntaxWarning when testing that the compiler removes constant statements. * test_grammar: ignore SyntaxWarning on the statement "1"

| | | | | | | | | | | | | | | | | | 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.

* | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 #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.

| | | | | | | | | | | | | | | | 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.

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
