* 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.)
* Fix of SF bug #475877 (Mutable subtype instances are hashable).Guido van Rossum2001-12-032-3/+17
| | | | | | | | | | | | | | | | | Rather than tweaking the inheritance of type object slots (which turns out to be too messy to try), this fix adds a __hash__ to the list and dict types (the only mutable types I'm aware of) that explicitly raises an error. This has the advantage that list.__hash__([]) also raises an error (previously, this would invoke object.__hash__([]), returning the argument's address); ditto for dict.__hash__. The disadvantage for this fix is that 3rd party mutable types aren't automatically fixed. This should be added to the rules for creating subclassable extension types: if you don't want your object to be hashable, add a tp_hash function that raises an exception. Also, it's possible that I've forgotten about other mutable types for which this should be done.
* Address SF patch #480716 as well as related issues.Guido van Rossum2001-12-031-17/+36
| | | | | | | | | | | | | | | | | | | SF patch #480716 by Greg Chapman fixes the problem that super's __get__ method always returns an instance of super, even when the instance whose __get__ method is called is an instance of a subclass of super. Other issues fixed: - super(C, C()).__class__ would return the __class__ attribute of C() rather than the __class__ attribute of the super object. This is confusing. To fix this, I decided to change the semantics of super so that it only applies to code attributes, not to data attributes. After all, overriding data attributes is not supported anyway. - While super(C, x) carefully checked that x is an instance of C, super(C).__get__(x) made no such check, allowing for a loophole. This is now fixed.

* PyString_FromFormatV, string_repr: document why these use sprintfTim Peters2001-12-031-5/+16

* Fix for SF bug #485678.Guido van Rossum2001-12-031-1/+1
| | | | | | | | slot_tp_descr_set(): When deleting an attribute described by a descriptor implemented in Python, the descriptor's __del__ method is called by the slot_tp_descr_set dispatch function. This is bogus -- __del__ already has a different meaning. Renaming this use of __del__ is renamed to __delete__.

* SF bug #487743: test_builtin fails on 64 bit platform.Tim Peters2001-12-011-1/+1
| | | | | | | | Bugfix candidate. int_repr(): we've never had a buffer big enough to hold the largest possible result on a 64-bit box. Now that we're using snprintf instead of sprintf, this can lead to nonsense results instead of random stack corruption.

* PyFile_WriteString(): change prototype so that the string arg isTim Peters2001-11-281-1/+1

| | | | | | | confusing error messages. If a new-style class has no sequence or mapping behavior, attempting to use the indexing notation with a non-integer key would complain that the sequence index must be an integer, rather than complaining that the operation is not supported.

* Add PyObject_CheckReadBuffer(), which returns true if its argumentJeremy Hylton2001-11-091-29/+35

* open_the_file(): this routine has a borrowed reference to the fileTim Peters2001-11-091-1/+0
| | | | | | object, so the "Metroworks only" section should not decref it in case of error (the caller is responsible for decref'ing in case of error -- and does).
* Fix SF buf #476953: Bad more for opening file gives bad msg.Jeremy Hylton2001-11-091-2/+6
| | | | | | If fopen() fails with EINVAL it means that the mode argument is invalid. Return the mode in the error message instead of the filename.

* Rehabilitated the fast-path richcmp code, and sped it up. It wasn'tTim Peters2001-11-041-31/+35
| | | | | | | | | | | | | | | helping for types that defined tp_richcmp but not tp_compare, although that's when it's most valuable, and strings moved into that category since the fast path was first introduced. Now it helps for same-type non-Instance objects that define rich or 3-way compares. For all the edits here, the rest just amounts to moving the fast path from do_richcmp into PyObject_RichCompare, saving a layer of function call (measurable on my box!). This loses when NESTING_LIMIT is exceeded, but I don't care about that (fast-paths are for normal cases, not pathologies). Also added a tasteful <wink> label to get out of PyObject_RichCompare, as the if/else nesting in this routine was getting incomprehensible.

* float_divmod(): the code wasn't sick enough to stop the MS optimizerTim Peters2001-11-011-1/+1

* SF bug #477221: abs and divmod act oddly with -0.0Tim Peters2001-11-011-9/+26
| | | | | | | Try to ensure that divmod(-0.0, 1.0) -> (-0.0, +0.0) across platforms. It always did on Windows, and still does. It didn't on Linux. Alas, there's no platform-independent way to write a test case for this. Bugfix candidate.

* PyFunction_Call() did not check the result of PyObject_Repr() for NULL, andFred Drake2001-11-011-2/+2
| | | | | | | should just avoid calling it in the first place to avoid waiting for a repr of a large object like a dict or list. The result of PyObject_Repr() was being leaked as well. Bugfix candidate!

* Add __del__ callbacks. They are too useful to leave out.Guido van Rossum2001-10-291-0/+74
| | | | | | | | | | | | | | | | XXX Remaining problems: - The GC module doesn't know about these; I think it has its reasons to disallow calling __del__, but for now, __del__ on new-style objects is called when the GC module discards an object, for better or for worse. - The code to call a __del__ handler is really ridiculously complicated, due to all the different debug #ifdefs. I've copied this from the similar code in classobject.c, so I'm pretty sure I did it right, but it's not pretty. :-( - No tests yet.
