This introduces:
- A new operator // that means floor division (the kind of division
where 1/2 is 0).
- The "future division" statement ("from __future__ import division)
which changes the meaning of the / operator to implement "true
division" (where 1/2 is 0.5).
- New overloadable operators __truediv__ and __floordiv__.
- New slots in the PyNumberMethods struct for true and floor division,
new abstract APIs for them, new opcodes, and so on.
I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.
Not yet implemented are warnings (default off) when / is used with int
or long arguments.
This has been on display since 7/31 as SF patch #443474.
Flames to /dev/null.
Also fix another bug caught by pychecker-- HTTPError() raised when
redirect limit exceed did not pass an fp object. Had to change method
to keep fp object around until it's certain that the error won't be
raised.
Remove useless line in do_proxy().
attribute values. Just using escape() can (and always has) led to broken
XML being generated. This makes sure it always produces the right thing.
This actually closes SF bug #440351.
break old code (in extreme cases). See SF bug #448153.
Add a new subclass IterableUserDict that has the __iter__ method.
Note that for new projects, unless backwards compatibility with
pre-2.2 Python is required, subclassing 'dictionary' is recommended;
UserDict might become deprecated.
__all__, to indicate these are implied as part of the public API.
IDLE's "Check Module" command uses this, and it broke once already
because the reset_globals() and tokeneater() functions were deleted
when Neil converted this to using the generator API of tokenizer.
(See SF bug #448835.)
starting the test suite proper. If _socket fails to build, that will
make this test fail with an ImportError -- handled by the test harness
as "no such module _socket" -- instead of an AttributeError deep in
CGIHTTPServer.
names of the test methods were not changed from the Zope-standard "check"
names to the Python-standard "test_" names, so the tests were not actually
being run.
Added test of hexadecimal character references as a regression check for
SF bug #445196.
Fix handling of hexadecimal character references (legal in XHTML) so that
they are properly interpreted as character references.
This fixes SF bug #445196.
If pyexpat is not available and more than one attempt is made to load
an expat-based xml parser, an empty xml.parser.expat module will be
created. This empty module will confuse xml.sax.expatreader into
thinking that pyexpat is available.
The ugly fix is to verify that the expat module actually defines the
names that are imported from pyexpat.
