revision 1.6 of structseq.c

Guido pointed out that I was missing a couple decrefs.

the branch.  I don't think it can break code, so the only risk
is introducing new bugs.  In that vein, can I ask -checkins readers
who have time to carefully look this over, check my refcounts &c?
TIA.

backport my checkin of
    revision 1.5 of structseq.c

Apply (my) patch:

[ 526072 ] pickling os.stat results round II

structseq's constructors can now take "invisible" fields in a dict.
Gave the constructors better error messages.
their __reduce__ method puts these fields in a dict.

(this is all in aid of getting os.stat_result's to pickle portably)

Also fixes

[ 526039 ] devious code can crash structseqs

Thought needed about how much of this counts as a bugfix.  Certainly
#526039 needs to be fixed.

    revision 1.14 of pickletester.py

Special support for pickling os.stat and os.stat_vfs results portably
(the types come from different modules on different platforms).

Added tests for pickling these types.

May be a bugfix candidate.

I haven't actually fixed this on the branch yet.  Will soon.

    revision 1.84 of setup.py
    revision 1.293 of configure.in

Apply Jack's patch attached to

[ 508779 ] Disable flat namespace on MacOS X

I presume you wanted this on the trunk too, Jack?

2.2.1 candidate.

Added support for SyncCGContextOriginWithPort
Added ClipCGContextToRegion

CGStubLib wasn't weak-linked, fixed.

    revision 1.24 of codecs.py

Set default value for readlines.sizehint to None. Change needed for 2.2.1
as well.

    revision 1.114 of longobject.c

_PyLong_Copy():  was creating a copy of the absolute value, but should
copy the sign too.  Added a test to test_descr to ensure that it does.

Bugfix candidate.

SF patch 514641 (Naofumi Honda) - Negative ob_size of LongObjects

that Tim didn't later back out.

    revision 1.116 of test_descr.py

_PyLong_Copy():  was creating a copy of the absolute value, but should
copy the sign too.  Added a test to test_descr to ensure that it does.

    revision 1.115 of test_descr.py

SF patch 514641 (Naofumi Honda) - Negative ob_size of LongObjects

Due to the bizarre definition of _PyLong_Copy(), creating an instance
of a subclass of long with a negative value could cause core dumps
later on.  Unfortunately it looks like the behavior of _PyLong_Copy()
is quite intentional, so the fix is more work than feels comfortable.

This fix is almost, but not quite, the code that Naofumi Honda added;
in addition, I added a test case.



I haven't quite worked out how to port the fix yet, but the test cases
can go straight over.

    revision 2.5 of pymem.h
    revision 2.44 of pyport.h

Whether platform malloc(0) returns NULL has nothing to do with whether
platform realloc(p, 0) returns NULL, so MALLOC_ZERO_RETURNS_NULL can
be correctly undefined yet realloc(p, 0) can return NULL anyway.

Prevent realloc(p, 0) doing free(p) and returning NULL via a different
hack.  Would probably be better to get rid of MALLOC_ZERO_RETURNS_NULL
entirely.

Bugfix candidate.

A fix & test for

SF patch  522961: Leak in Python/thread_nt.h, from Gerald S. Williams.
A file-static "threads" dict mapped thread IDs to Windows handles, but

There were never tests for the fact that list() always returns a *new*

return a reference to the argument when it is a tuple.  Now there are.
