Martin v. Löwis 0073f2e428 Fix --disable-unicode compilation problems. 2002-11-21 23:52:35 +00:00
Tim Peters 7d791240c0 float_int(): Some systems raise an exception if a double is cast to
long but the double is too big to fit in a long.  Prevent that.  This
closes some recent bug or patch on SF, but SF is down now so I can't
say which.

Bugfix candidate.

Walter Dörwald f171540ab8 Change int() so that passing a string, unicode, float or long argument
that is outside the integer range no longer raises OverflowError, but
returns a long object instead.

This fixes SF bug http://www.python.org/sf/635115

Neil Schemenauer ce30bc9f49 Add nb_remainder (i.e. __mod__) slot to unicode type. Fixes SF bug #615506. 2002-11-18 16:10:18 +00:00
Neil Schemenauer a6cd4e65d7 Add nb_remainder (i.e. __mod__) slot to str type. Fixes SF bug #615506. 2002-11-18 16:09:38 +00:00
Neil Schemenauer 2c77e90804 Improve exception message raised by PyFloat_AsDouble if the object does not
have a nb_float slot.  This matches what PyInt_AsLong does.

Neil Schemenauer 26db587485 str and unicode objects now have a __mod__ slot so don't special case them in
PyNumber_Remainder().  This fixes SF bug #615506 and allows string and unicode
subclasses to override __mod__.

Neil Schemenauer 89350a41b9 Remove _Py_ResetReferences. Fixes bug #529750 "Circular reference makes
Py_Init crash".  refchain cannot be cleared because objects can live across
Py_Finalize() and Py_Initialize() if they are kept alive by circular
references.

Tim Peters 9a6b8d8cf8 Repaired illegal syntax most compilers probably let slide (but MSVC
treats as a fatal error).

Guido van Rossum 1f1213120e Use the new C3 MRO algorithm, implemented by Samuele Pedroni (SF patch
619475; also closing SF bug 618704).  I tweaked his code a bit for
style.

This raises TypeError for MRO order disagreements, which is an
improvement (previously these went undetected) but also a degradation:
what if the order disagreement doesn't affect any method lookups?
I don't think I care.

Neal Norwitz 80a1bf4b5d Fix SF # 635969, No error "not all arguments converted"
When mwh added extended slicing, strings and unicode became mappings.
Thus, dict was set which prevented an error when doing:
	newstr = 'format without a percent' % string_value

This fix raises an exception again when there are no formats
and % with a string value.

Tim Peters b9099c3df4 SF patch 637176: list.sort crasher
Armin Rigo's Draconian but effective fix for

SF bug 453523: list.sort crasher

slightly fiddled to catch more cases of list mutation.  The dreaded
internal "immutable list type" is gone!  OTOH, if you look at a list
*while* it's being sorted now, it will appear to be empty.  Better
than a core dump.

Walter Dörwald 07e147667c Make int("...") return a long if an int would overflow.
Also remove the 512 character limitation for int(u"...") and long(u"...").

This closes SF bug #629989.

Michael W. Hudson 5da854fe51 This is Alex Martelli's patch
[ 633870 ] allow any seq assignment to a list slice

plus a very silly little test case of my own.

Michael W. Hudson 173f11da5d Some days, I think my comment of
/* this is harder to get right than you might think */

angered some God somewhere.  After noticing

    >>> range(5000000)[slice(96360, None, 439)]
    []

I found that my cute test for the slice being empty failed due to
overflow.  Fixed, and added simple test (not the above!).

Guido van Rossum f740bdf337 Since properties are supported here, is possible that
instance_getattr2() raises an exception.  Fix all code that made this
assumption.

Backport candidate.

Guido van Rossum 617080b6cf Fix (real! :-) memory leaks in half_cmp and half_binop.
Perhaps found by NealN and valgrind.  Will forward port.
2002-10-18 14:15:33 +00:00
Guido van Rossum 3930bc35d0 Sigh. That wasn't a memory leak, that was Guido committing before
running tests.  Withdraw 2.183 and its backport.
2002-10-18 13:51:49 +00:00
Guido van Rossum 72297bb71e Fix memory leak in add_subclass() found by NealN with valgrind.

Guido van Rossum 6e5680fc83 For some reason (probably cut and paste), __ipow__ for new-style
classes was called with three arguments.  This makes no sense, there's
no way to pass in the "modulo" 3rd argument as for __pow__, and
classic classes don't do this.  [SF bug 620179]

I don't want to backport this to 2.2.2, because it could break
existing code that has developed a work-around.  Code in 2.2.2 that
wants to use __ipow__ and wants to be forward compatible with 2.3
should be written like this:

  def __ipow__(self, exponent, modulo=None):
      ...

Guido van Rossum a5c0e6d6c8 Add checks for size overflow on list*n, list+list, tuple+tuple.
Will backport.
2002-10-11 21:05:56 +00:00
Guido van Rossum 6e08c1460c PyObject_Init[Var] is almost always called from the PyObject_NEW[_VAR]
macros.  The 'op' argument is then the result from PyObject_MALLOC,
and that can of course be NULL.  In that case, PyObject_Init[Var]
would raise a SystemError with "NULL object passed to
PyObject_Init[Var]".  But there's nothing the caller of the macro can
do about this.  So PyObject_Init[Var] should call just PyErr_NoMemory.

Will backport.

Martin v. Löwis a5f0907d79 Back out #479898. 2002-10-11 05:37:59 +00:00
Guido van Rossum 049cd6b563 Fix a nasty endcase reported by Armin Rigo in SF bug 618623:
'%2147483647d' % -123 segfaults.  This was because an integer overflow
in a comparison caused the string resize to be skipped.  After fixing
the overflow, this could call _PyString_Resize() with a negative size,
so I (1) test for that and raise MemoryError instead; (2) also added a
test for negative newsize to _PyString_Resize(), raising SystemError
as for all bad arguments.

An identical bug existed in unicodeobject.c, of course.

Will backport to 2.2.2.

Guido van Rossum 8052f8921e Undo this part of the previous checkin:
Also fixed an error message -- %s argument has non-string str()
  doesn't make sense for %r, so the error message now differentiates
  between %s and %r.

because PyObject_Repr() and PyObject_Str() ensure that this can never
happen.  Added a helpful comment instead.
2002-10-09 19:14:30 +00:00
Guido van Rossum b00c07f038 The string formatting code has a test to switch to Unicode when %s
sees a Unicode argument.  Unfortunately this test was also executed
for %r, because %s and %r share almost all of their code.  This meant
that, if u is a unicode object while repr(u) is an 8-bit string
containing ASCII characters, '%r' % u is a *unicode* string containing
only ASCII characters!

Fixed by executing the test only for %s.

Also fixed an error message -- %s argument has non-string str()
doesn't make sense for %r, so the error message now differentiates
between %s and %r.

Michael W. Hudson 5c1ad84d7f Fix for platforms where int != long. 2002-09-12 09:31:30 +00:00
Guido van Rossum 02fe64708f Insert an overflow check when the sequence repetition count is outside
the range of ints.  The old code would pass random truncated bits to
sq_repeat() on a 64-bit machine.

Backport candidate.
2002-09-11 19:00:52 +00:00
Guido van Rossum d4774fb6ef Untested code for 64-bit platforms. range_length() is declared as int
but returns r->len which is a long.  This doesn't even cause a warning
on 32-bit platforms, but can return bogus values on 64-bit platforms
(and should cause a compiler warning).  Fix this by inserting a range
check when LONG_MAX != INT_MAX, and adding an explicit cast to (int)
when the test passes.  When r->len is out of range, PySequence_Size()
and hence len() will report an error (but an iterator will still
work).

Michael W. Hudson 02ff6a9952 A slight change to SET_LINENO-less tracing.
