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

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.
Fixes http://bugs.python.org/issue1233 - bsddb.dbshelve.DBShelf.append
was useless due to inverted logic. Also adds a test case for RECNO dbs
to test_dbshelve.
Avoid exception if there's a stray directory inside a Maildir folder.
The Maildir specification doesn't seem to say anything about this
situation, and it can happen if you're keeping a Maildir mailbox in
Subversion (.svn directories) or some similar system. The patch just
ignores directories in the cur/, new/, tmp/ folders.
a large width is passed on 32-bit platforms. Found by Google.
It would be good for people to review this especially carefully and verify
I don't have an off by one error and there is no other way to cause overflow.

Correct the name of a field in the WIN32_FIND_DATAA and WIN32_FIND_DATAW structures.
Closes bug #1726026.

Add code to read from master_fd in the parent, breaking when we get an OSError
(EIO can occur on Linux) or there's no more data to read. Without this,
test_pty.py can hang on the waitpid() because the child is blocking on the
stdout write. This will definitely happen on Mac OS X and could potentially
happen on other platforms. See the comment for details.
Fix utf-8-sig incremental decoder, which didn't recognise a BOM when the
first chunk fed to the decoder started with a BOM, but was longer than 3 bytes.
SF #1685563, MSVCCompiler creates redundant and long PATH strings
If MSVCCompiler.initialize() was called multiple times, the path
would get duplicated. On Windows, this is a problem because the
path is limited to 4k. There's no benefit in adding a path multiple
times, so prevent that from occuring. We also normalize the path
before checking for duplicates so things like /a and /a/ won't both
be stored.

because that prevented the shared library from being used.
(backport from rev. 54634)
Python 2.5 added support for explicit relative import statements and
yield expressions, which were missing in the manual.
Also fix grammar productions that used the names from the Grammar file,
markup that broke the generated grammar.txt, and wrap some lines that
broke the pdf output.

and creates a BackgroundBrowser then.
