Neal Norwitz 8355dd5806 Backport 55874:
Fix a bug when there was a newline in the string expandtabs was called on.
This also catches another condition that can overflow.

Neal Norwitz 66e64e2b6a Prevent expandtabs() on string and unicode objects from causing a segfault when
a large width is passed on 32-bit platforms.  Found by Google.

It would be good for people to review this especially carefully and verify
I don't have an off by one error and there is no other way to cause overflow.

Kristján Valur Jónsson a1392d5ace Merge change 54982 from the trunk. This fixes the test_subprocess test in the testsuite for VisualStudio2005 builds, by "sanitizing" the "mode" that is used in the posixmodule's fdopen(). In particular the non-standard "U" mode character is removed. 2007-05-07 19:25:38 +00:00
Kristján Valur Jónsson dffe9a214b the nb_long slot on classobject instances now defaults to call the nb_int slot member if there is no __long__ attribute found. This is in accordance with a suggestion from Armin Rigo, and allows the test_getargs2.py test in the testsuite for x64 2007-05-07 18:36:39 +00:00
Kristján Valur Jónsson f4601d874f Fix two problems that emerged when the testsuite was run with an x64 build: PyLong_FromSSize_t incorrectly assumed an unsigned object, and itertools.count() had the wrong upper limit for the iterator. 2007-05-07 18:30:48 +00:00

Brett Cannon 75ba075110 If you created a weakref in an object's __del__ method to itself it would
segfault the interpreter during weakref clean up.  Now any new weakrefs created
after __del__ is run are removed silently.

Fixes bug #1377858 and the weakref_in_del crasher for new-style classes.
Classic classes are still affected.

Thomas Wouters e471317a08 Backport trunk revision 53527:
SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize

When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.

This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)

Fix warnings with HP's C compiler.  It doesn't recognize that infinite

Armin Rigo 4b63c21d6f Forward-port of r52136: 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...
