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
shadowing of __year, __month, __day and the use of proxies.
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.
"""
atomically, but deepcopy() didn't support this at all.
I don't see any reason for this, so I'm adding ClassType
to the set of types that are deep-copied atomically.
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()
* Check that starmap()'s argument returns a tuple
* Verify that imap()'s tuple re-use is safe
* Make a similar tuple re-use (with safety check) for izip()
Reverting one of those irritating "security fixes". fdopen() opens
files in binary mode. That makes pydoc skip the \r\n on Windows that's
need to make the output readable in the shell. Screw it.
