Amaury Forgeot d'Arc a40d573664 #3720: Interpreter crashes when an evil iterator removes its own next function.
Now the slot is filled with a function that always raises.

Will not backport: extensions compiled with 2.6.x would not run on 2.6.0.

Antoine Pitrou 0668c62677 Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Travis E. Oliphant 3781aef8f8 Finish backporting new buffer API to Python 2.6. Left to do: memoryview object and structmodule. But, these need to be finished in Python 3.0 first. No objects support the new buffer API in Python 2.6 as of yet, and except for the memoryview object, I don't think they will. 2008-03-18 04:44:57 +00:00
Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Eric Smith 3f91437e5f In PyNumber_ToBase, changed from an assert to returning an error when PyObject_Index() returns something other than an int or long. It should never be possible to trigger this, as PyObject_Index checks to make sure it returns an int or long. 2008-02-15 12:14:32 +00:00
Christian Heimes e247f0037f Use a static and interned string for __subclasscheck__ and __instancecheck__ as suggested by Thomas Heller in #2115 2008-02-14 22:40:11 +00:00
Eric Smith 5e527ebee1 Added PyNumber_ToBase and supporting routines _PyInt_Format and
_PyLong_Format.  In longobject.c, changed long_format to
_PyLong_Format.  In intobject.c, changed uses of PyOS_snprintf to
_PyInt_Format instead.

_PyLong_Format is similar to py3k's routine of the same name, except
it has 2 additional parameters: addL and newstyle.  addL was existing
in long_format, and controls adding the trailing "L".  This is
unneeded in py3k.  newstyle is used to control whether octal prepends
"0" (the pre-2.6 style), or "0o" (the 3.0 sytle).

PyNumber_ToBase is needed for PEP 3127 (Integer Literal Support and
Syntax) and PEP 3101 (Advanced String Formatting).

This changeset does not need merging into py3k.

Guido van Rossum b55911378f Patch # 1026 by Benjamin Aranguren (with Alex Martelli):
Backport abc.py and isinstance/issubclass overloading to 2.6.

I had to backport test_typechecks.py myself, and make one small change
to abc.py to avoid duplicate work when x.__class__ and type(x) are the
same.

Brett Cannon 1e534b5425 Fix a crasher where Python code managed to infinitely recurse in C code without
ever going back out to Python code in PyObject_Call().  Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

Armin Rigo 7ccbca93a2 Forward-port of r52136,52138: a review of overflow-detecting code.
* unified the way intobject, longobject and mystrtoul handle
  values around -sys.maxint-1.

* in general, trying to entierely avoid overflows in any computation
  involving signed ints or longs is extremely involved.  Fixed a few
  simple cases where a compiler might be too clever (but that's all
  guesswork).

* more overflow checks against bad data in marshal.c.

* 2.5 specific: fixed a number of places that were still confusing int
  and Py_ssize_t.  Some of them could potentially have caused
  "real-world" breakage.

* list.pop(x): fixing overflow issues on x was messy.  I just reverted
  to PyArg_ParseTuple("n"), which does the right thing.  (An obscure
  test was trying to give a Decimal to list.pop()... doesn't make
  sense any more IMHO)

* trying to write a few tests...

Neal Norwitz 271a8689e9 Subclasses of int/long are allowed to define an __index__. 2006-08-15 06:29:03 +00:00
Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Georg Brandl b0061c8e93 Remove "non-mapping" and "non-sequence" from TypeErrors raised by
PyMapping_Size and PySequence_Size.

Because len() tries first sequence, then mapping size, it will always
raise a "non-mapping object has no len" error which is confusing.

Armin Rigo 53c1692f6a Fix for an obscure bug introduced by revs 46806 and 46808, with a test.
The problem of checking too eagerly for recursive calls is the
following: if a RuntimeError is caused by recursion, and if code needs
to normalize it immediately (as in the 2nd test), then
PyErr_NormalizeException() needs a call to the RuntimeError class to
instantiate it, and this hits the recursion limit again...  causing
PyErr_NormalizeException() to never finish.

Moved this particular recursion check to slot_tp_call(), which is not
involved in instantiating built-in exceptions.

Backport candidate.
