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.
This bug happened because: 1) the scanner_search and scanner_match methods
were not checking the buffer limits before increasing the current pointer;
and 2) SRE_SEARCH was using "if (ptr == end)" as a loop break, instead of
"if (ptr >= end)".
* Modules/_sre.c
(SRE_SEARCH): Check for "ptr >= end" to break loops, so that we don't
hang forever if a pointer passing the buffer limit is used.
(scanner_search,scanner_match): Don't increment the current pointer
if we're going to pass the buffer limit.

Mention the fix.
* Lib/distutils/command/bdist_rpm.py
(bdist_rpm.initialize_options): Included verify_script attribute.
(bdist_rpm.finalize_package_data): Ensure that verify_script is a filename.
(bdist_rpm._make_spec_file): Included verify_script in script_options
tuple.

* Modules/_sre.c
(lastmark_restore): New function, implementing algorithm to restore
a state to a given lastmark. In addition to the similar algorithm used
in a few places of SRE_MATCH, restore lastindex when restoring lastmark.
(SRE_MATCH): Replace lastmark inline restoring by lastmark_restore(),
function. Also include it where missing. In SRE_OP_MARK, set lastindex
only if i > lastmark.

The last round boosted "the limit" from 2GB to 4GB. This round gets
rid of the 4GB limit. For files > 4GB, gzip stores just the last 32
bits of the file size, and now we play along with that too. Tested
by hand (on a 6+GB file) on Win2K.
Boosting from 2GB to 4GB was arguably enough "a bugfix". Going beyond
that smells more like "new feature" to me.
Fixed the signed/unsigned confusions when dealing with files >= 2GB.
4GB is still a hard limitation of the gzip file format, though.
Testing this was a bitch on Win98SE due to frequent system freezes. It
didn't freeze while running gzip, it kept freezing while trying to *create*
a > 2GB test file! This wasn't Python's doing. I don't know of a
reasonable way to test this functionality in regrtest.py, so I'm not
checking in a test case (a test case would necessarily require creating
a 2GB+ file first, using gzip to zip it, using gzip to unzip it again,
and then compare before-and-after; so >4GB free space would be required,
and a loooong time; I did all this "by hand" once).
Bugfix candidate, I guess.
sys.getwindowsversion() on Windows (new enahanced Tim-proof <wink>
version), and fix test_pep277.py in a few minor ways.

fairly large, most are caused by reformatting section and subsection
headings. The changes fall into the following categories:
* reformatted section and subsection headers.
* escaped isolated asterisks which would be interpreted as starting bold
or italic text (e.g. "void (*)(PyObject \*)").
* quoted stuff that looks like internal references but isn't
(e.g. ``PyCmp_``).
* changed visually balanced quotes to just use apostrophes
(e.g. "'string'" instead of "`string'").
* introduced and indenting multiline chunks of code.
* created one table (search for "New codecs").

This adds two new functions to mimetypes:
guess_all_extensions() which returns a list of all known
extensions for a mime type, and add_type() which adds one
mapping between a mime type and an extension.
interning. I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged. Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.
