* String annotations [PEP 563] (#4390)Guido van Rossum2018-01-261-2/+24
| | | | | | | | * Document `from __future__ import annotations` * Provide plumbing and tests for `from __future__ import annotations` * Implement unparsing the AST back to string form This is required for PEP 563 and as such only implements a part of the unparsing process that covers expressions.
* bpo-31113: Get rid of recursion in the compiler for normal control flow. (#3015)Serhiy Storchaka2018-01-111-78/+104

* bpo-32365: Fix a reference leak when compile __debug__. (#4916)Serhiy Storchaka2017-12-181-4/+4

* bpo-27169: The __debug__ constant is now optimized out at compile time. (#4880)Serhiy Storchaka2017-12-151-30/+15

* bpo-29469: Move constant folding to AST optimizer (GH-2858)INADA Naoki2017-12-141-0/+4

* bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675)Nick Coghlan2017-12-031-5/+0
| | | | | | | | 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.

| * 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.

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