This gets the test working on Solaris. It seems a little hokey to me,
but the test passed on Linux and Solaris, hopefully other platforms too.

Complete revamp of PCBuild8 directory. Use subdirectories for each project under the main pcbuild solution. Now make extensive use of property sheets to simplify project configuration. x64 build fully supported, and the process for building PGO version (Profiler Guided Optimization) simplified. All projects are now present, except _ssl, which needs to be reimplemented. Also, some of the projects that require external libraries need extra work to fully compile on x64.

When accessing the .value attribute of a c_wchar_p instance, and the
instance does not point to a valid wchar_t zero-terminated string,
raise a ValueError. c_char_p does this already.

The ValueError message now contains the correct pointer address.

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?\194?\180t 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.

r55197 | collin.winter | 2007-05-08 21:14:36 -0700 (Tue, 08 May 2007) | 9 lines

Fix a bug in test.test_support.open_urlresource().

If the call to requires() doesn't precede the filesystem check, we get the following situation:
1. ./python Lib/test/regrtest.py test_foo # test needs urlfetch, not enabled, so skipped
2. ./python Lib/test/regrtest.py -u urlfetch test_foo # test runs
3. ./python Lib/test/regrtest.py test_foo # test runs (!)

By moving the call to requires() *before* the filesystem check, the fact that fetched files are cached on the local disk becomes an implementation detail, rather than a semantics-changing point of note.

Wed, 14 Jun 2006 04:09:25 +0000

SequenceMatcher.get_matching_blocks(): This now guarantees that
adjacent triples in the result list describe non-adjacent matching
blocks. That's _nice_ to have, and Guido said he wanted it.

Not a bugfix candidate: Guido or not ;-), this changes visible
endcase semantics (note that some tests had to change), and
nothing about this was documented before. Since it was working
as designed, and behavior was consistent with the docs, it wasn't
"a bug".

Mostly in SequenceMatcher.{__chain_b, find_longest_match}:
This now does a dynamic analysis of which elements are so frequently
repeated as to constitute noise. The primary benefit is an enormous
speedup in find_longest_match, as the innermost loop can have factors
of 100s less potential matches to worry about, in cases where the
sequences have many duplicate elements. In effect, this zooms in on
sequences of non-ubiquitous elements now.

While I like what I've seen of the effects so far, I still consider
this experimental. Please give it a try!
