* Apply (my) patch:Michael W. Hudson2002-03-061-23/+76
| | | | | | | | | | | | | | | | | [ 526072 ] pickling os.stat results round II structseq's constructors can now take "invisible" fields in a dict. Gave the constructors better error messages. their __reduce__ method puts these fields in a dict. (this is all in aid of getting os.stat_result's to pickle portably) Also fixes [ 526039 ] devious code can crash structseqs Thought needed about how much of this counts as a bugfix. Certainly #526039 needs to be fixed.
* A fix & test forMichael W. Hudson2002-03-051-1/+30
| | | | | | | | [ 496873 ] structseqs unpicklable by adding a __reduce__ method to structseqs. Will also commit this to the 2.2.1 branch momentarily.
* Whether platform malloc(0) returns NULL has nothing to do with whetherTim Peters2002-03-021-5/+2
| | | | | | | | | | | platform realloc(p, 0) returns NULL, so MALLOC_ZERO_RETURNS_NULL can be correctly undefined yet realloc(p, 0) can return NULL anyway. Prevent realloc(p, 0) doing free(p) and returning NULL via a different hack. Would probably be better to get rid of MALLOC_ZERO_RETURNS_NULL entirely. Bugfix candidate.
* _PyLong_Copy(): was creating a copy of the absolute value, but shouldTim Peters2002-03-021-1/+1
| | | | | | copy the sign too. Added a test to test_descr to ensure that it does. Bugfix candidate.
* Revert the last odd change to PyNumber_Long: the problem it was tryingTim Peters2002-03-021-10/+2
| | | | to fix was almost certainly a bug in _PyLong_Copy (which I'll fix next).
* SF patch 514641 (Naofumi Honda) - Negative ob_size of LongObjectsGuido van Rossum2002-03-012-4/+18
| | | | | | | | | | Due to the bizarre definition of _PyLong_Copy(), creating an instance of a subclass of long with a negative value could cause core dumps later on. Unfortunately it looks like the behavior of _PyLong_Copy() is quite intentional, so the fix is more work than feels comfortable. This fix is almost, but not quite, the code that Naofumi Honda added; in addition, I added a test case.

| | | | | | | | | | | | Objects/ fileobject.c stringobject.c unicodeobject.c This commit doesn't include the cleanup patches for stringobject.c and unicodeobject.c which are shown separately in the patch manager. Those patches will be regenerated and applied in a subsequent commit, so as to preserve a fallback position (this commit to those files).

* Fix to the UTF-8 encoder: it failed on 0-length input strings.Marc-André Lemburg2002-02-071-6/+17
| | | | | | | | | | | | | | Fix for the UTF-8 decoder: it will now accept isolated surrogates (previously it raised an exception which causes round-trips to fail). Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for marshalling Unicode objects, so we better make sure it works for all Unicode code points, including isolated surrogates). Bumped the PYC magic in a non-standard way -- please review. This was needed because the old PYC format used illegal UTF-8 sequences for isolated high surrogates which now raise an exception.

* - PyType_Ready(): Initialize the ob_type field to &PyType_Type if it'sGuido van Rossum2001-12-171-0/+16
| | | | | | | | NULL, so that you can call PyType_Ready() to initialize a type that is to be separately compiled with C on Windows. inherit_special(): Add a long comment explaining that you have to set tp_new if your base class is PyBaseObject_Type.

* (Merge into trunk.)Guido van Rossum2001-12-141-1/+3
| | | | | | | | | | | | | | | | | Fix for SF bug #492345. (I could've sworn I checked this in, but apparently I didn't!) This code: class Classic: pass class New(Classic): __metaclass__ = type attempts to create a new-style class with only classic bases -- but it doesn't work right. Attempts to fix it so it works caused problems elsewhere, so I'm now raising a TypeError in this case.
* Ensure that complex() only accepts a string argument as the first arg,Fred Drake2001-12-131-1/+13
| | | | | and only if there is no second arg. This closes SF patch #479551.
* float_floor_div: An expression like 3.//1j crashed the interpreter, orTim Peters2001-12-111-9/+12
| | | | | | | delivered bizarre results. Check float_divmod for a Py_NotImplemented return and pass it along (instead of treating Py_NotImplemented as a 2-tuple). CONVERT_TO_DOUBLE: Added comments; this macro is obscure.
* float_int_div(): For clarity, move this closer to the other floatTim Peters2001-12-111-16/+16
| | | | division functions, and rename to float_floor_div.
* SF bug #491415 PyDict_UpdateFromSeq2() unusedTim Peters2001-12-111-8/+2
| | | | | | | PyDict_UpdateFromSeq2(): removed it. PyDict_MergeFromSeq2(): made it public and documented it. PyDict_Merge() docs: updated to reveal <wink> that the second argument can be any mapping object.
* Make sure that when we invoke callback functions associated with weakFred Drake2001-12-101-20/+24
| | | | | | references, we do not allow any outstanding exceptions "leak" into the callback's execution state. This closes SF bug #478534.
* Well what do you know. The Python implementation contained the sameGuido van Rossum2001-12-101-2/+2

* Fix the Python property class in a comment right.Guido van Rossum2001-12-101-22/+23
|
* property_descr_get(): Fix a curious bug in the property() type: whenGuido van Rossum2001-12-101-5/+5
| | | | | | | | | | no get function was defined, the property's doc string was inaccessible. This was because the test for prop_get was made *before* the test for a NULL/None object argument. Also changed the property class defined in Python in a comment to test for NULL to decide between get and delete; this makes it less Python but then, assigning None to a property doesn't delete it!
* SF patch #491049 (David Jacobs): Small PyString_FromString optimizationGuido van Rossum2001-12-101-1/+1
| | | | | | PyString_FromString(): Since the length of the string is already being stored in size, changed the strcpy() to a memcpy() for a small speed improvement.
* _PyTuple_Resize(): this dumped core on tuple(globals()) for me. TurnsGuido van Rossum2001-12-071-6/+8
| | | | | | | | | | | out the for loop at the end intended to zero out new items wasn't doing anything, because sv->ob_size was already equal to newsize. The fix slightly refactors the function, introducing a variable oldsize and doing away with sizediff (which was used only once), and using oldsize and newsize consistently. I also added comments explaining what the two for loops do. (Looking at the CVS annotation of this function, it's no miracle a bug crept in -- this has been patched by many different folks! :-)
* PyString_FromString: this requires its argument be non-NULL, but doesn'tTim Peters2001-12-061-1/+4
| | | | check it. Added an assert() to that effect.
* Fix for #489669 (Neil Norwitz): memory leak in test_descr (unicode).Guido van Rossum2001-12-061-6/+3
| | | | | | | | | | | | | | This is best reproduced by while 1: class U(unicode): pass U(u"xxxxxx") The unicode_dealloc() code wasn't properly freeing the str and defenc fields of the Unicode object when freeing a subtype instance. Fixed this by a subtle refactoring that actually reduces the amount of code slightly.
* Fix memory leak in dict_to_map(), SF bug [ #485152 ] memory leak in test_scope.Jeremy Hylton2001-12-061-8/+11
| | | | | | | | | | | | PyCell_Set() incremenets the reference count, so the earlier XINCREF causes a leak. Also make a number of small performance improvements to the code on the assumption that most of the time variables are not rebound across a FastToLocals() / LocalsToFast() pair. Replace uses of PyCell_Set() and PyCell_Get() with PyCell_SET() and PyCell_GET(), since the frame is guaranteed to contain cells.
* Little stuff.Jeremy Hylton2001-12-061-8/+9
| | | | | | | | | | | Add a missing DECREF in an obscure corner. If the str() or repr() of an object passed to a string interpolation -- e.g. "%s" % obj -- returns a non-string, the returned object was leaked. Repair an indentation glitch. Replace a bunch of PyString_AsString() calls (and their ilk) with macros.
* The previous checkin to clear __slots__ variables did a little bit ofGuido van Rossum2001-12-061-20/+20
| | | | | the work each time it found another base class. All the work is contiguous, so we might as well do it all at once at the end.
* Fix SF bug #489581: __slots__ leak.Guido van Rossum2001-12-051-2/+22
| | | | | | It was easier than I thought, assuming that no other things contribute to the instance size besides slots -- a pretty good bet. With a test suite, no less!
* At the PythonLabs meeting someone mentioned it would make Jim reallyGuido van Rossum2001-12-051-2/+2
| | | | | | | | | happy if one could delete the __dict__ attribute of an instance. I love to make Jim happy, so here goes... - New-style objects now support deleting their __dict__. This is for all intents and purposes equivalent to assigning a brand new empty dictionary, but saves space if the object is not used further.
* SF bug #488480: integer multiply to return -max_int-1.Tim Peters2001-12-041-127/+63
| | | | | | | int_mul(): new and vastly simpler overflow checking. Whether it's faster or slower will likely vary across platforms, favoring boxes with fast floating point. OTOH, we no longer have to worry about people shipping broken LONG_BIT definitions <0.9 wink>.
* Fix SF bug #486144: Uninitialized __slot__ vrbl is None.Guido van Rossum2001-12-041-2/+4
| | | | | | | There's now a new structmember code, T_OBJECT_EX, which is used for all __slot__ variables (except __weakref__, which has special behavior anyway). This new code raises AttributeError when the variable is NULL rather than converting NULL to None.
* long_mul(): The PyNumber_Multiply() call can return a long if theGuido van Rossum2001-12-041-0/+6
| | | | | result would overflow an int. Check for this. (SF bug #488482, Armin Rigo.)
* PyObject_Generic{Get,Set}Attr(): ensure that the attribute name is aGuido van Rossum2001-12-041-20/+72
| | | | | | | string object (or a Unicode that's trivially converted to ASCII). PyObject_GetAttr(): add an 'else' to the Unicode test like PyObject_SetAttr() already has.
* function_call(): Remove a bogus (and I mean *really* bogus) call toGuido van Rossum2001-12-031-1/+0
| | | | | Py_DECREF(arg) after the PyErr_NoMemory() call. (Armin Rigo, SF bug #488477.)
