Brett Cannon 77ae87c11e Remove file-level typedefs that were inconsistently used throughout the file.
Just move over to the public API names.

Closes issue1238.

Neal Norwitz 6ba1a5f51b Coverity #151: Remove deadcode.
All this code already exists above starting at line 653.

Raymond Hettinger 8f6693701c enumerate() is no longer bounded to using sequences shorter than LONG_MAX. The possibility of overflow was sending some newsgroup posters into a tizzy. 2007-10-03 21:18:11 +00:00
Brett Cannon 31ba8480d8 Fix error introduced by r58288; if a tuple is length 0 return its repr and
don't worry about any self-referring tuples.

Brett Cannon 0b14f243c4 tuple.__repr__ did not consider a reference loop as it is not possible from
Python code; but it is possible from C.  object.__str__ had the issue of not
expecting a type to doing something within it's tp_str implementation that
could trigger an infinite recursion, but it could in C code..  Both found
thanks to BaseException and how it handles its repr.

Closes issue #1686386.  Thanks to Thomas Herve for taking an initial stab at
coming up with a solution.

Guido van Rossum ad8fb0d47c Patch # 188 by Philip Jenvey.
Make tell() mark CRLF as a newline.
With unit test.

Facundo Batista d544df7ddd Issue #1772851. Alters long.__hash__ from being *almost* completely
predictable to being completely predictable.  The value of hash(n)
is unchanged for any n that's small enough to be representable as an
int, and also unchanged for the vast majority of long integers n of
reasonable size.

Thomas Wouters bbaff4c7e8 Properly indent two lines. (Spotted because it caused merge conflicts in the
py3k branch ;)
2007-09-18 23:27:30 +00:00
Brett Cannon 0153159e67 Add a bunch of GIL release/acquire points in tp_print implementations and for
PyObject_Print().

Closes issue #1164.
2007-09-17 03:28:34 +00:00
Brett Cannon 4c20bc40d7 Generators had their throw() method allowing string exceptions. That's a
no-no.

Fixes issue #1147.  Need to fix 2.5 to raise a proper warning if a string
exception is passed in.

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 a0c05512ec Fix a possible segfault from recursing too deep to get the repr of a list.
Closes issue #1096.
2007-09-10 21:38:27 +00:00
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.

Thomas Wouters 3ccec68a05 Improve extended slicing support in builtin types and classes. Specifically:
- Specialcase extended slices that amount to a shallow copy the same way as
   is done for simple slices, in the tuple, string and unicode case.

 - Specialcase step-1 extended slices to optimize the common case for all
   involved types.

 - For lists, allow extended slice assignment of differing lengths as long
   as the step is 1. (Previously, 'l[:2:1] = []' failed even though
   'l[:2] = []' and 'l[:2:None] = []' do not.)

 - Implement extended slicing for buffer, array, structseq, mmap and
   UserString.UserString.

 - Implement slice-object support (but not non-step-1 slice assignment) for
   UserString.MutableString.

 - Add tests for all new functionality.

Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.
2007-07-21 06:55:02 +00:00
Georg Brandl 7c3b50db66 Patch #1673759: add a missing overflow check when formatting floats
with %G.
2007-07-12 08:38:00 +00:00
Walter Dörwald 84a3efec37 Add T_PYSSIZET in structmember.h: This can be used for
Py_ssize_t members.

Simplify the implementation of UnicodeError objects:
start and end attributes are now stored directly as
Py_ssize_t members, which simplifies various get and
set functions.

Neal Norwitz 5c9a81a3d8 Fix a bug when there was a newline in the string expandtabs was called on.
This also catches another condition that can overflow.

Will backport.
2007-06-11 02:16:10 +00:00
Neal Norwitz 7dbd2a3720 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.

Martin v. Löwis da587ab43e Bug #1733488: Fix compilation of bufferobject.c on AIX.
Will backport to 2.5.

Neal Norwitz 8b2bfbc198 Add -3 option to the interpreter to warn about features that are
deprecated and will be changed/removed in Python 3.0.

This patch is mostly from Anthony.  I tweaked some format and added
a little doc.

Brett Cannon 5cd0fca9d8 Complete deprecation of BaseException.message. Some subclasses were directly
accessing the message attribute instead of using the descriptor.
2007-05-17 02:02:56 +00:00
Neal Norwitz d501d1fbc4 Port rev 55353 from Guido:
Add what looks like a necessary call to PyErr_NoMemory() when PyMem_MALLOC()
fails.

Will backport.

Guido van Rossum 360496d9c0 Fix a bug in test_c_api() that caused a negative refcount. 2007-05-10 17:20:15 +00:00
Kristján Valur Jónsson abe1d48d20 As per Armin Rigo's suggestion, remove special handing from intobject.c to deal with the peculiarities of classobject's implementation of the number protocol. The nb_long method of classobject now falls back to nb_int if there is no __long__ attribute present. 2007-05-07 16:46:54 +00:00
Brett Cannon 229cee2d3d Deprecate BaseException.message as per PEP 352. 2007-05-05 01:34:02 +00:00
Kristján Valur Jónsson f030394de3 Fix problems in x64 build that were discovered by the testsuite:
- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows.  There is only Itanium and x64.  Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h.  The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier.  Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.

With these changes, the x64 passes the testsuite, for those modules present.
2007-05-03 20:27:03 +00:00
Neal Norwitz 8b267b55ef Remove dead code. This code couldn't be reached because earlier in
the function there is another check for z != Py_None.

Armin Rigo 9790a27065 Fix for #1303614 and #1174712:
- __dict__ descriptor abuse for subclasses of built-in types
- subclassing from both ModuleType and another built-in types

Thanks zseil for the patch.

Kristján Valur Jónsson 0a440d4184 Export function sanitize_the_mode from fileobject.c as _PyFile_SanitizeMode(). Use this function in posixmodule.c when implementing fdopen(). This fixes test_subprocess.py for a VisualStudio 2005 compile. 2007-04-26 09:15:08 +00:00

Armin Rigo c0ba52d3fd Revert r53997 as per
http://mail.python.org/pipermail/python-dev/2007-March/071796.html .

I've kept a couple of still-valid extra tests in test_descr, but didn't
bother to sort through the new comments and refactorings added in r53997
to see if some of them could be kept.  If so, they could go in a
follow-up check-in.

Neal Norwitz cbd9ee69ee When __slots__ are set to a unicode string, make it work the same as
setting a plain string, ie don't expand to single letter identifiers.

Georg Brandl c02e13122b Add some missing NULL checks which trigger crashes on low-memory conditions.
Found by Victor Stinner. Will backport when 2.5 branch is unfrozen.
2007-04-11 17:16:24 +00:00
Guido van Rossum f102e24bd3 Add a type.__init__() method that enforces the same signature as
type.__new__(), and then calls object.__init__(cls), just to be anal.

This allows us to restore the code in string.py's _TemplateMetaclass
that called super(...).__init__(name, bases, dct), which I commented
out yesterday since it broke due to the stricter argument checking
added to object.__init__().
