the same object to be collected by the cyclic GC support if they are
only referenced by a cycle. If the weakref being collected was one of
the weakrefs without callbacks, some local variables for the
constructor became invalid and have to be re-computed.
The test caused a segfault under a debug build without the fix applied.

initialization was interfering and causing the sending socket to be not
ready. Add an IO ready test to fix this. Moved the polling IO ready test
into pollpacket().

patch removes dependencies on the old unsupported KoreanCodecs package
and the alternative JapaneseCodecs package. Since both of those
provide aliases for their codecs, this removal just makes the generic
codec names work.
We needed to make slight changes to __init__() as well.
This will be backported to Python 2.3 when its branch freeze is over.
The chief benefit of this change is that requests will now use
HTTP/1.1 instead of HTTP/1.0. Bump the module version number as part
of the change.
There are two possible incompatibilities that we'll need to watch out
for when we get to an alpha release. We may get a different class of
exceptions out of httplib, and the do_open() method changed its
signature. The latter is only important if anyone actually subclasses
AbstractHTTPHandler.
John J. Lee writes: "the patch makes it possible to implement
functionality like HTTP cookie handling, Refresh handling,
etc. etc. using handler objects. At the moment urllib2's handler
objects aren't quite up to the job, which results in a lot of
cut-n-paste and subclassing. I believe the changes are
backwards-compatible, with the exception of people who've
reimplemented build_opener()'s functionality -- those people would
need to call opener.add_handler(HTTPErrorProcessor).
The main change is allowing handlers to implement
methods like:
http_request(request)
http_response(request, response)
In addition to the usual
http_open(request)
http_error{_*}(...)
"
Note that the change isn't well documented at least in part because
handlers aren't well documented at all. Need to fix this.
Add a bunch of new tests. It appears that none of these tests
actually use the network, so they don't need to be guarded by a
resource flag.

Use case: Sometimes 'compiling' source files (with SWIG, for example)
creates additionl files which included by later sources. The win32all
setup script requires this.
There is no SF item for this, but it was discussed on distutils-sig:
http://mail.python.org/pipermail/distutils-sig/2003-November/003514.html
by request of Donovan Preston. In return, he promised to use this
to create a Python OSA component, which would turn Python
into a first-class OSA scripting language (like AppleScript itself).

that the docs only promise lengths up to 2048. Unfortunately this no
longer tests for the segfault I was seeing earlier, but I'm confident
I've nailed that one. :-) Fixes SF 852281. Will backport to 2.3.

This addresses most of the remaining semantic changes promised by
PEP 237, except for repr() of a long, which still shows the trailing
'L'. The PEP appears to promise warnings for operations that
changed semantics compared to Python 2.3, but this is not
implemented; we've suffered through enough warnings related to
hex/oct literals and I think it's best to be silent now.

have been there since weakrefs were introduced.

the email.Header.Header class, which has a more sophisticated

subtype_dealloc(): This left the dying object exposed to gc, so that
if cyclic gc triggered during the weakref callback, gc tried to delete
the dying object a second time. That's a disaster. subtype_dealloc()
had a (I hope!) unique problem here, as every normal dealloc routine
untracks the object (from gc) before fiddling with weakrefs etc. But
subtype_dealloc has obscure technical reasons for re-registering the
dying object with gc (already explained in a large comment block at
the bottom of the function).
The fix amounts to simply refraining from reregistering the dying object
with gc until after the weakref callback (if any) has been called.
This is a critical bug (hard to predict, and causes seemingly random
memory corruption when it occurs). I'll backport it to 2.3 later.
Formerly, underlying queue was implemented in terms of two lists. The
new queue is a series of singly-linked fixed length lists.
The new implementation runs much faster, supports multi-way tees, and
allows tees of tees without additional memory costs.
The root ideas for this structure were contributed by Andrew Koenig
and Guido van Rossum.
memory leak that would've occurred for all iterators that were
destroyed before having iterated until they raised StopIteration.
* Simplify some code.
* Add new test cases to check for the memleak and ensure that mixing
iteration with modification of the values for existing keys works.
* tee object is no longer subclassable
* independent iterators renamed to "itertools.tee_iterator"
* fixed doc string typo and added entry in the module doc string
* Fixed typo in docstring for 'failUnlessAlmostEqual()'
* Removed unnecessary use of 'float()' for time values.
* Removed apparently unnecessary import of unittest. At some point in
the distant past I believe it was necessary otherwise the 'TestCase'
that a module saw was not the same as the 'TestCase' seen within
'unittest', and the user's TestCase subclasses were not recognised as
subclasses of the TestCase seen within unittest. Seems not to be
necessary now.
