Martin v. Löwis b0d71d0ec6 Implement PyObject_DelItemString. Fixes #498915. 2002-01-05 10:50:30 +00:00
Neal Norwitz 649b75954a SF Patch #494863, file.xreadlines() should raise ValueError if file is closed
This makes xreadlines behave like all other file methods
(other than close() which just returns).

Fred Drake 2a908f6b7b proxy_compare(): Make sure that we unwrap both objects being compared if
both are proxy objects.

Guido van Rossum f884b74910 - PyType_Ready(): Initialize the ob_type field to &PyType_Type if it's
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.

Guido van Rossum e54616cb6f (Merge into trunk.)
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.

Fred Drake 526c7a0101 Ensure that complex() only accepts a string argument as the first arg,
and only if there is no second arg.
This closes SF patch #479551.

Tim Peters 77d8a4fc91 float_floor_div: An expression like 3.//1j crashed the interpreter, or
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.
2001-12-11 20:31:34 +00:00
Tim Peters 63a3571e17 float_int_div(): For clarity, move this closer to the other float
division functions, and rename to float_floor_div.

Tim Peters f582b82fe9 SF bug #491415 PyDict_UpdateFromSeq2() unused
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.

Fred Drake ef8ebd1e74 Make sure that when we invoke callback functions associated with weak
references, we do not allow any outstanding exceptions "leak" into the
callback's execution state.
This closes SF bug #478534.

Guido van Rossum 7171f1c8d8 Well what do you know. The Python implementation contained the same
bug as the C code. :-(

Guido van Rossum ba2485f947 Fix the Python property class in a comment right. 2001-12-10 18:03:34 +00:00
Guido van Rossum b75ba918d6 property_descr_get(): Fix a curious bug in the property() type: when
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!

Guido van Rossum 169192e818 SF patch #491049 (David Jacobs): Small PyString_FromString optimization
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.
2001-12-10 15:45:54 +00:00
Guido van Rossum f70590f990 _PyTuple_Resize(): this dumped core on tuple(globals()) for me. Turns
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! :-)
2001-12-07 20:00:04 +00:00
Tim Peters 62de65b25e PyString_FromString: this requires its argument be non-NULL, but doesn't
check it.  Added an assert() to that effect.

Guido van Rossum 604ddf80d8 Fix for #489669 (Neil Norwitz): memory leak in test_descr (unicode).
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.

Jeremy Hylton 1a48ca8c53 Fix memory leak in dict_to_map(), SF bug [ #485152 ] memory leak in test_scope.
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.
2001-12-06 15:48:16 +00:00
Jeremy Hylton 7802a53e38 Little stuff.
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.

Guido van Rossum 14227b4dd4 The previous checkin to clear __slots__ variables did a little bit of
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.
2001-12-06 02:35:58 +00:00
Guido van Rossum 33bab01da6 Fix SF bug #489581: __slots__ leak.
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!

Guido van Rossum d331cb5502 At the PythonLabs meeting someone mentioned it would make Jim really
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.

Tim Peters a3c01ce696 SF bug #488480: integer multiply to return -max_int-1.
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>.
2001-12-04 23:05:10 +00:00
Guido van Rossum 64b206c19e Fix SF bug #486144: Uninitialized __slot__ vrbl is None.
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.
2001-12-04 17:13:22 +00:00
Guido van Rossum 03b3f04542 long_mul(): The PyNumber_Multiply() call can return a long if the
result would overflow an int.  Check for this.  (SF bug #488482, Armin
Rigo.)
2001-12-04 16:36:39 +00:00
Guido van Rossum ebca9fc1ba PyObject_Generic{Get,Set}Attr(): ensure that the attribute name is a
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.
2001-12-04 15:54:53 +00:00
Guido van Rossum be5234610a function_call(): Remove a bogus (and I mean *really* bogus) call to
Py_DECREF(arg) after the PyErr_NoMemory() call.  (Armin Rigo, SF bug
#488477.)
2001-12-03 19:22:38 +00:00
Guido van Rossum dbb53d9918 Fix of SF bug #475877 (Mutable subtype instances are hashable).
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.

Guido van Rossum 5b443c6282 Address SF patch #480716 as well as related issues.
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.

Guido van Rossum 1d5b3f29ff Fix for SF bug #485678.
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__.

Martin v. Löwis d132750206 Patch 487906: update inline docs. 2001-12-02 18:09:41 +00:00
Tim Peters 422210426e SF bug #487743: test_builtin fails on 64 bit platform.
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.

Jack Jansen b3be216b41 Merged changes made on r22b2-branch between r22b2 and r22b2-mac (the
changes from start of branch upto r22b2 were already merged, of course).
2001-11-30 14:16:36 +00:00
Tim Peters 97019e4110 PyFloat_AsStringEx(): This function takes an output char* but doesn't
pass the buffer length.  Stop using it.  It should be deprecated, but too
late in the release cycle to do that now.
New static format_float() does the same thing but requires passing the
buffer length too.  Use it instead.
2001-11-28 22:43:45 +00:00
Tim Peters c1bbcb87aa PyFile_WriteString(): change prototype so that the string arg is
const char* instead of char*.  The change is conceptually correct, and
indirectly fixes a compiler wng introduced when somebody else innocently
passed a const char* to this function.
