Martin v. Löwis	725507b52e	Change int to Py_ssize_t in several places. Add (int) casts to silence compiler warnings. Raise Python exceptions for overflows.	20 years ago
Thomas Wouters	f7f438ba3b	SF patch #1438387 , PEP 328: relative and absolute imports. - 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.	20 years ago

Jeremy Hylton	af68c874a6	Add const to several API functions that take char . 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 *.	21 years ago

Jeremy Hylton	ec97a28b60	Fix a bunch of imports to use code.h instead of compile.h. Remove duplicate declarations from compile.h	21 years ago
Jeremy Hylton	3e0055f8c6	Merge ast-branch to head 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.	21 years ago

Jeremy Hylton	4c989ddc9c	Subclasses of string can no longer be interned. The semantics of 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.	22 years ago

Raymond Hettinger	66bd233225	Completed the patch for Bug #215126 . * Fixes an incorrect variable in a PyDict_CheckExact. * Allow general mapping locals arguments for the execfile() function and exec statement. * Add tests.	22 years ago
Neil Schemenauer	3a313e3655	Check the type of values returned by __int__, __float__, __long__, __oct__, and __hex__. Raise TypeError if an invalid type is returned. Note that PyNumber_Int and PyNumber_Long can still return ints or longs. Fixes SF bug #966618.	22 years ago
Michael W. Hudson	30ea2f223f	This closes patch: [ 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.	22 years ago

Raymond Hettinger	214b1c3aae	SF Bug #215126 : Over restricted type checking on eval() function The builtin eval() function now accepts any mapping for the locals argument. Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing down the normal case. My timings so no measurable impact.	22 years ago
