| | | | | | | | | | | | | | | | | | | | | | | | objimpl.h, pymem.h: Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE} to PyObject_{Free, FREE} in a release build. They're aliases for the system free() now. _subprocess.c/sp_handle_dealloc(): Since the memory was originally obtained via PyObject_NEW, it must be released via PyObject_FREE (or _DEL). pythonrun.c, tokenizer.c, parsermodule.c: I lost count of the number of PyObject vs PyMem mismatches in these -- it's like the specific function called at each site was picked at random, sometimes even with memory obtained via PyMem getting released via PyObject. Changed most to use PyObject uniformly, since the blobs allocated are predictably small in most cases, and obmalloc is generally faster than system mallocs then. If extension modules in real life prove as sloppy as Python's front end, we'll have to revert the objimpl.h + pymem.h part of this patch. Note that no problems will show up in a debug build (all calls still go thru obmalloc then). Problems will show up only in a release build, most likely segfaults.

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-13/+28
| | | | | | | | | | | | | | | | | | | | | | | - 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.

* Check return result from Py_InitModule*(). This API can fail.Neal Norwitz2006-01-191-0/+2

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-9/+9
| | | | | | | | | | | | | | | | | | | 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 *.

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-191-6/+115
| | | | | | | | | | | | | | (Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.

* SF patch [ 597919 ] compiler package and SET_LINENOJeremy Hylton2002-12-311-6/+7
| | | | | | | | | | | | | | | | | A variety of changes from Michael Hudson to get the compiler working with 2.3. The primary change is the handling of SET_LINENO: # The set_lineno() function and the explicit emit() calls for # SET_LINENO below are only used to generate the line number table. # As of Python 2.3, the interpreter does not have a SET_LINENO # instruction. pyassem treats SET_LINENO opcodes as a special case. A few other small changes: - Remove unused code from pycodegen and pyassem. - Fix error handling in parsermodule. When PyParser_SimplerParseString() fails, it sets an exception with detailed info. The parsermodule was clobbering that exception and replacing it was a generic "could not parse string" exception. Keep the original exception.

* staticforward bites the dust.Jeremy Hylton2002-07-171-12/+7
| | | | | | | | | | | | | | | The staticforward define was needed to support certain broken C compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the static keyword when it was used with a forward declaration of a static initialized structure. Standard C allows the forward declaration with static, and we've decided to stop catering to broken C compilers. (In fact, we expect that the compilers are all fixed eight years later.) I'm leaving staticforward and statichere defined in object.h as static. This is only for backwards compatibility with C extensions that might still use it. XXX I haven't updated the documentation.

* Disambiguate the grammar for backtick.Guido van Rossum2002-05-241-1/+13
| | | | | | The old syntax suggested that a trailing comma was OK inside backticks, but in fact (due to ideosyncrasies of pgen) it was not. Fix the grammar to avoid the ambiguity. Fred: you may want to update the refman.
* Patch supplied by Burton Radons for his own SF bug #487390: ModifyingGuido van Rossum2001-12-081-1/+1
| | | | | | | | | | | | | type.__module__ behavior. This adds the module name and a dot in front of the type name in every type object initializer, except for built-in types (and those that already had this). Note that it touches lots of Mac modules -- I have no way to test these but the changes look right. Apologies if they're not. This also touches the weakref docs, which contains a sample type object initializer. It also touches the mmap test output, because the mmap type's repr is included in that output. It touches object.h to put the correct description in a comment.

Note that if the testlist contains more than one test, a trailing comma is still allowed, for maximum backward compatibility; but this example is not: [(x, y) for x in range(10), for y in range(10)] ^ The fix involved creating a new nonterminal 'testlist_safe' whose definition doesn't allow the trailing comma if there's only one test: testlist_safe: test [(',' test)+ [',']]
