- Issue #1336: fix a race condition in subprocess.Popen if the garbage
collector kicked in at the wrong time that would cause the process
to hang when the child wrote to stderr.
Fix for #1303614 and #1174712:
- __dict__ descriptor abuse for subclasses of built-in types
- subclassing from both ModuleType and another built-in types
- Issue829951: In the smtplib module, SMTP.starttls() now complies with
RFC 3207 and forgets any knowledge obtained from the server not obtained
from the TLS negotiation itself. Patch contributed by Bill Fenner.

Raise an error instead of crashing with a segfault when a NULL
function pointer is called.
Will backport to release25-maint.

the art. It now complies latest specification and tests.
The only difference of this version with the one in the trunk
is that a small subset that hash tests were removed, because
they rely on modifications to core hash() function (see
issue 1182 for further details).
Add a hack (originally devised in a slightly different form by Thomas Wouters)
to prevent spurious tracebacks when a daemon thread's cleanup happens to wake
up when the world around it has already been destroyed.
This also backports other small changes to this file, essentially making
it identical to the trunk version.
Fix for #1444: utf_8_sig.StreamReader was (indirectly through decode())
calling codecs.utf_8_decode() with final==True, which falled with incomplete
byte sequences. Fix and test by James G. Sack.
When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set. This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.
It is necessary to save/restore the exception around the call to the trace
function.
This happens a lot with py3k: isinstance() of an ABCMeta instance runs
def __instancecheck__(cls, instance):
"""Override for isinstance(instance, cls)."""
return any(cls.__subclasscheck__(c)
for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.
And the problem can be reproduced in 2.5 with pure python code.
Undoes incorrect dbtables fix and errant strdup introduced as
described below:
r58757 | gregory.p.smith | 2007-11-01 14:08:14 -0700 (Thu, 01 Nov 2007) | 4 lines
Fix bug introduced in revision 58385. Database keys could no longer
have NULL bytes in them. Replace the errant strdup with a
malloc+memcpy. Adds a unit test for the correct behavior.
r58758 | gregory.p.smith | 2007-11-01 14:15:36 -0700 (Thu, 01 Nov 2007) | 3 lines
Undo revision 58533 58534 fixes. Those were a workaround for
a problem introduced by 58385.
r58759 | gregory.p.smith | 2007-11-01 14:17:47 -0700 (Thu, 01 Nov 2007) | 2 lines
false "fix" undone as correct problem was found and fixed.
- Fix bsddb.dbtables: Don't randomly corrupt newly inserted rows by
picking a rowid string with null bytes in it. Such rows could not
later be deleted, modified or individually selected. Existing
bsdTableDb databases created with such rows are out of luck.
- Use mkdtemp for the test_dbtables test database environment and
clean it up afterwards using shutil.rmtree.
