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.

mistake in his code, I'm adding a note explaining that you should call
settimeout() before connect().

* Use Py_RETURN_NONE everywhere.
* Fix-up the firstpass check for the tp_print slot.

Simplifies and speeds-up the code.

* Used the flag to optimize set.__contains__(), dict.__contains__(),
  dict.__getitem__(), and list.__getitem__().

* show that it is typically used with sorted data,
* highlight commonalities with SQL's groupby and Unix's uniq,
* demonstrate valid uses for the default identity function,
* add some excitement by suggesting the range of possibilities.

a real subtype of Cm.ComponentInstance right now, it turns out that is
too difficult.
- OSA.OSAComponentInstance initializer does accept a Cm.ComponentInstance
instance, though, so at least things are becoming useable.

MSVC isn't able to read them.  Thanks to David Rushby.

two framework builds (in /Library and /System/Library) to coexist
with distutils linking against the right one.

Should be backported to 2.3, but getting Apple-supplied Python to pick
up these fixes is going to be non-trivial.

$(prefix) wasn't communicated to Mac/OSX/Makefile for all targets. Fixed.

The example code did not work and could not easily be made to work.
Since the docs were already complex and the feature was not used
(it took two years for the errors to surface), we decided to dedocument
it entirely, leaving unittest cleaner than before.
