the optional proto 2 slot state.
pickle.py, load_build(): CAUTION: Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved. There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.
pickletester.py, test_pickle.py: Got rid of the hack for
exempting cPickle from running some of the proto 2 tests.

test_linuxaudiodev.py) are no longer run by default. This is
because they don't always work, depending on your hardware and
software. To run these tests, you must use an invocation like
./python Lib/test/regrtest.py -u audio test_ossaudiodev
with an indented code block but no newline would raise SyntaxError.
This would have been a four-line change in parsetok.c... Except
codeop.py depends on this behavior, so a compilation flag had to be
invented that causes the tokenizer to revert to the old behavior;
this required extra changes to 2 .h files, 2 .c files, and 2 .py
files. (Fixes SF bug #501622.)
and loading them via the other, except for the special cases of this
Guido added to test_datetime.py for datetime module objects. The new
test_xpickle.py tries all of pickletester's AbstractPickleTests in
both x-module ways.
This changes the default __new__ to refuse arguments iff tp_init is the
default __init__ implementation -- thus making it a TypeError when you
try to pass arguments to a constructor if the class doesn't override at
least __init__ or __new__.
"Unsigned" (i.e., positive-looking, but really negative) hex/oct
constants with a leading minus sign are once again properly negated.
The micro-optimization for negated numeric constants did the wrong
thing for such hex/oct constants. The patch avoids the optimization
for all hex/oct constants.
This needs to be backported to Python 2.2!

the IDE) after installing.
descr_check(); it wasn't useful. Change the type argument of the
various _get() methods to PyObject * because the call signature of
tp_descr_get doesn't guarantee its type.
object is not a real str or unicode but an instance
of a subclass, construct the output via looping
over __getitem__. This guarantees that the result
is the same for function==None and function==lambda x:x
This doesn't happen for tuples, because filtertuple()
uses PyTuple_GetItem().
(This was discussed on SF bug #665835).
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.
Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().
Sets.py:
* Replace old ifilter() usage with new.
tickle the 2.2.2 __cmp__ bug test_datetime used to tickle, so the
workarounds for that bug no longer make sense in the test suite (which I'm
still trying to keep as closely in synch as possible with Zope3's
version).
__ne__ no longer complain if they don't know how to compare to the other
thing. If no meaningful way to compare is known, saying "not equal" is
sensible. This allows things like
if adatetime in some_sequence:
and
somedict[adatetime] = whatever
to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.
It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().
the tests will remain in sync:
"""
Tres discovered a weird bug when a datetime is pickled, caused by the

Here's a quick fix and a quick unit test. I don't quite understand
why this wasn't caught by the pickling unit tests.

I don't see any reason for this, so I'm adding ClassType

eventProc (which simply drops all events on the floor). Also added a
method SetDefaultEventProc through which frameworks can set a global
event handler (which can still be overridden on a per-call basis
with the eventProc argument).
* Fixed typo in exception message for times()
* Filled in missing times_traverse()
* Document reasons that imap() did not adopt a None fill-in feature
* Document that count(sys.maxint) will wrap-around on overflow
* Add overflow test to islice()

* Make a similar tuple re-use (with safety check) for izip()

simplifying the setup/teardown methods; is that worth doing?
Apparently MAC OS 9 doesn't have POSIX-conforming timestamps. A test
fails as a result, but at least for this specific test it's easy enough
to get the POSIX epoch out of it.
This patch adds stdin, stdout as optional arguments to the cmd.Cmd
constructor (defaulting to sys.stdin, sys.stdout), and changes the Cmd
methods throughout to use self.stdout.write() and self.stdin.foo for
output and input. This allows much greater flexibility for using cmd -
for instance, hooking it into a telnet server.
Patch for library module and for documentation.
gzip shouldn't raise ValueError on corrupt files
Currently the gzip module will raise a ValueError if the file was
corrupt (bad crc or bad size). I can't see how that applies to
reading a corrupt file. IOError seems better, and it's what code
will likely be looking for.
guarantee to keep valid pointers in its slots.
tests: Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places. Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.
Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.
blindly assumed that tp_as_sequence->sq_item always returns
a str or unicode object. This might fail with str or unicode
subclasses.
This patch checks whether the object returned from __getitem__
is a str/unicode object and raises a TypeError if not (and
the filter function returned true).
Furthermore the result for __getitem__ can be more than one
character long, so checks for enough memory have to be done.
this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).
I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code. This risk doesn't exist for the
extension registry.

huge. On older Linux systems, the C library's strtod() apparently
gives up before seeing the end of the string when it sees so many
digits that it thinks the result must be Infinity. (It is wrong, BTW
-- there could be an "e-10000" hiding behind 10,000 digits.) The
shorter shuge still tests what it's testing, without relying on
strtod() doing a super job.
exception, ResourceDenied. This is used to distinguish between tests that
are skipped for other reasons (platform support, missing data, etc.) from
those that are skipped because a "resource" has not been enabled. This
prevents those tests from being reported as unexpected skips for the
platform; those should only be considered unexpected skips if the resource
were enabled.

loops. Renamed DATA and BINDATA to DATA0 and DATA1. Included
disassemblies, but noted why we can't test them. Added XXX comment to
cPickle about a mysterious comment, where pickle and cPickle diverge
in how they number PUT indices.
Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's
no need to do things like multiply by sizeof(char) in hairy malloc
arguments. Fixed an undetected-overflow bug in readline_file().
longobject.c: Fixed a really stupid bug in the new _PyLong_NumBits.
pickle.py: Fixed stupid bug in save_long(): When proto is 2, it
wrote LONG1 or LONG4, but forgot to return then -- it went on to
append the proto 1 LONG opcode too.
Fixed equally stupid cancelling bugs in load_long1() and
load_long4(): they *returned* the unpickled long instead of pushing
it on the stack. The return values were ignored. Tests passed
before only because save_long() pickled the long twice.
Fixed bugs in encode_long().
Noted that decode_long() is quadratic-time despite our hopes,
because long(string, 16) is still quadratic-time in len(string).
It's hex() that's linear-time. I don't know a way to make decode_long()
linear-time in Python, short of maybe transforming the 256's-complement
bytes into marshal's funky internal format, and letting marshal decode
that. It would be more valuable to make long(string, 16) linear time.
pickletester.py: Added a global "protocols" vector so tests can try
all the protocols in a sane way. Changed test_ints() and test_unicode()
to do so. Added a new test_long(), but the tail end of it is disabled
because it "takes forever" under pickle.py (but runs very quickly under
cPickle: cPickle proto 2 for longs is linear-time).
