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.

Facundo Batista e139688d34 Issue 2112. mmap does not raises EnvironmentError no more, but
a subclass of it. Thanks John Lenton.

Christian Heimes 7adfad850a Bug #2111: mmap segfaults when trying to write a block opened with PROT_READ

Neal Norwitz e1027f9034 Use int for the sign rather than a char. char can be signed or unsigned.
It's system dependent.  This might fix the problem with test_rfind failing.

Neal Norwitz 448654f1f8 Mostly reformat. Also set an error and return NULL if neither MS_WINDOWS
nor UNIX is defined.  This may have caused problems on cygwin.
2008-01-27 07:36:03 +00:00
Neal Norwitz 739a3c40e6 Cleanup the code a bit. test_rfind is failing on PPC and PPC64 buildbots,
this might fix the problem.

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

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 96a8c3954c Make use of METH_O and METH_NOARGS where possible.

Guido van Rossum 38fff8c4e4 Checking in the code for PEP 357.
This was mostly written by Travis Oliphant.
I've inspected it all; Neal Norwitz and MvL have also looked at it
(in an earlier incarnation).

in function calls.

Tim Peters 23721ee96c Removed pointless parens around `return` expressions;
deleted some curlies around one-line blocks.

Tim Peters e564e7f939 new_mmap_object(), Windows flavor.
On a box where sizeof(size_t) == 4, C doesn't define
what happens when a size_t value is shifted right by
32 bits, and this caused test_mmap to fail on Windows
in a debug build.  So use different code to break
the size apart depending on how large size_t actually
is.

This looks like an illusion, since lots of code in this
module still appears to assume sizes can't be more
than 32 bits (e.g., the internal _GetMapSize() still
returns an int), but at least test_mmap passes again.

Neal Norwitz 0e6bc8c260 Patch #1407135, bug #1424041, make mmap.mmap(-1, length) work the same
on both Unix (SVR4 and BSD) and Windows.  Restores behaviour of passing -1
for anonymous memory on Unix.  Use MAP_ANONYMOUS instead of _ANON since
the latter is deprecated according to Linux (gentoo) man pages.

Should we continue to allow mmap.mmap(0, length) to work on Windows?
0 is a valid fd.

Will backport bugfix portions.

Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail.
Probably should be backported.

Neal Norwitz 3b4fff8079 Fix SF bug #1402308, segfault when using mmap(-1, ...)
This didn't crash on Linux, but valgrind complained.
I'm not sure if this test is valid on Windows.

Will backport.
