| * Issue #23722: improve __classcell__ compatibilityNick Coghlan2016-12-051-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Issue #23722: Initialize __class__ from type.__new__()Nick Coghlan2016-09-111-5/+10
| | | | | | | | | | | | | | | | | | 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.
* | Rework CALL_FUNCTION* opcodesVictor Stinner2016-09-091-89/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more efficient bytecode: * CALL_FUNCTION now only accepts position arguments * CALL_FUNCTION_KW accepts position arguments and keyword arguments, but keys of keyword arguments are packed into a constant tuple. * CALL_FUNCTION_EX is the most generic, it expects a tuple and a dict for positional and keyword arguments. CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed. 2 tests of test_traceback are currently broken: skip test, the issue #28050 was created to track the issue. Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka and Victor Stinner.

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

* | compiler: don't emit SyntaxWarning on const stmtVictor Stinner2016-02-081-22/+2

* | 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"

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
