* Patch #2477: Added from __future__ import unicode_literalsChristian Heimes2008-03-261-0/+1
| | | | The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.
* Backport of the print function, using a __future__ import.Eric Smith2008-03-181-1/+2
| | | | | | | | This work is substantially Anthony Baxter's, from issue 1633807. I just freshened it, made a few minor tweaks, and added the test cases. I also created issue 2412, which is to check for 2to3's behavior with the print function. I also added myself to ACKS.
* #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and ↵Christian Heimes2007-12-191-2/+2
| | | | Py_REFCNT. Macros for b/w compatibility are available.
* PEP 3123: Provide forward compatibility with Python 3.0, while keepingMartin v. Löwis2007-07-211-2/+2
| | | | | backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and PyVarObject_HEAD_INIT.

| | | | | | Applied patch zombie-frames-2.diff from sf patch 876206 with updates for Python 2.5 and also modified to retain the free_list to avoid the 67% slow-down in pybench recursion test. 5% speed up in function call pybench.

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | - IMPORT_NAME takes an extra argument from the stack: the relativeness of the import. Only passed to __import__ when it's not -1. - __import__() takes an optional 5th argument for the same thing; it __defaults to -1 (old semantics: try relative, then absolute) - 'from . import name' imports name (be it module or regular attribute) from the current module's *package*. Likewise, 'from .module import name' will import name from a sibling to the current module. - Importing from outside a package is not allowed; 'from . import sys' in a toplevel module will not work, nor will 'from .. import sys' in a (single-level) package. - 'from __future__ import absolute_import' will turn on the new semantics for import and from-import: imports will be absolute, except for from-import with dots. Includes tests for regular imports and importhooks, parser changes and a NEWS item, but no compiler-package changes or documentation changes.
* Per discussion on python-dev, remove CO_GENERATOR_ALLOWED. Leave comment ↵Neal Norwitz2006-02-251-1/+4

This change implements a new bytecode compiler, based on a transformation of the parse tree to an abstract syntax defined in Parser/Python.asdl. The compiler implementation is not complete, but it is in stable enough shape to run the entire test suite excepting two disabled tests.
