* The filter() function does support a None argument in Py3.0.Raymond Hettinger2008-03-191-7/+0

* Backport of the print function, using a __future__ import.Eric Smith2008-03-181-0/+73
| | | | | | | | 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.

* Finish backporting new buffer API to Python 2.6. Left to do: memoryview ↵Travis E. Oliphant2008-03-181-0/+1
| | | | object and structmodule. But, these need to be finished in Python 3.0 first. No objects support the new buffer API in Python 2.6 as of yet, and except for the memoryview object, I don't think they will.
* Add a little info to the 3k deprecation warnings about what to use instead.Neal Norwitz2008-02-241-4/+4

* Backport of PEP 3101, Advanced String Formatting, from py3k.Eric Smith2008-02-171-0/+19
| | | | | | | | | | | | | | | Highlights: - Adding PyObject_Format. - Adding string.Format class. - Adding __format__ for str, unicode, int, long, float, datetime. - Adding builtin format. - Adding ''.format and u''.format. - str/unicode fixups for formatters. The files in Objects/stringlib that implement PEP 3101 (stringdefs.h, unicodedefs.h, formatter.h, string_format.h) are identical in trunk and py3k. Any changes from here on should be made to trunk, and changes will propogate to py3k).

* Continue rolling back pep-3141 changes that changed behavior from 2.5. ThisJeffrey Yasskin2008-01-051-17/+25
| | | | | | | | | | | | round included: * Revert round to its 2.6 behavior (half away from 0). * Because round, floor, and ceil always return float again, it's no longer necessary to have them delegate to __xxx___, so I've ripped that out of their implementations and the Real ABC. This also helps in implementing types that work in both 2.6 and 3.0: you return int from the __xxx__ methods, and let it get enabled by the version upgrade. * Make pow(-1, .5) raise a ValueError again.
* Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (justJeffrey Yasskin2008-01-031-23/+30

The only significant difference is that round(x) returns a float to preserve backward-compatibility. See http://bugs.python.org/issue1689.

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | | - 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.

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

* Merge ast-branch to headJeremy Hylton2005-10-201-1/+1
| | | | | | | | | | 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.
