* 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 *.

* Fix a bunch of imports to use code.h instead of compile.h.Jeremy Hylton2005-10-211-1/+0
| | | | Remove duplicate declarations from compile.h
* 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.

* Subclasses of string can no longer be interned. The semantics ofJeremy Hylton2004-08-071-0/+5
| | | | | | | | | | | interning were not clear here -- a subclass could be mutable, for example -- and had bugs. Explicitly interning a subclass of string via intern() will raise a TypeError. Internal operations that attempt to intern a string subclass will have no effect. Added a few tests to test_builtin that includes the old buggy code and verifies that calls like PyObject_SetAttr() don't fail. Perhaps these tests should have gone in test_string.

| | | | | | | | | | | | | | | | | [ 960406 ] unblock signals in threads although the changes do not correspond exactly to any patch attached to that report. Non-main threads no longer have all signals masked. A different interface to readline is used. The handling of signals inside calls to PyOS_Readline is now rather different. These changes are all a bit scary! Review and cross-platform testing much appreciated.
