* Speed-up "x in y" where x has more than one character.
The existing code made excessive calls to the expensive memcmp() function.
The new code uses memchr() to rapidly find a start point for memcmp().
In addition to knowing that the first character is a match, the new code
also checks that the last character is a match. This significantly reduces
the incidence of false starts (saving memcmp() calls and making quadratic
behavior less likely).
Improves the timings on:
python -m timeit -r7 -s"x='a'*1000" "'ab' in x"
python -m timeit -r7 -s"x='a'*1000" "'bc' in x"
Once this code has proven itself, then string_find_internal() should refer
to it rather than running its own version. Also, something similar may
apply to unicode objects.
Thanks to Robert Dick <dickrp@ece.northwestern.edu> for reporting this bug
and submitting a patch.
Adjust doc(object) to display useful documentation for plain values (e.g.
help([]) now shows the methods on the list instead of just printing "[]").
(This change has been tested interactively, by generating docs for the
standard library, and by running the module documentation webserver.)

`glob.glob()` currently calls itself recursively to build a list of matches of
the dirname part of the pattern and then filters by the basename part. This is
effectively BFS. ``glob.glob('*/*/*/*/*/foo')`` will build a huge list of all
directories 5 levels deep even if only a handful of them contain a ``foo``
entry. A generator-based recusion would never have to store these list at once
by implementing DFS. This patch converts the `glob` function to an `iglob`
recursive generator . `glob()` now just returns ``list(iglob(pattern))``.
I also cleaned up the code a bit (reduced duplicate `has_magic()` checks and
created a second `glob0` helper func so that the main loop need not be
duplicated).
Thanks to Cherniavsky Beni for the patch!
test_threading.test_foreign_thread(): new test does a basic check that
"foreign" threads can using the threading module, and that they create
a _DummyThread instance in at least one use case. This isn't a very
good test, since a thread created by thread.start_new_thread() isn't
particularly "foreign".
_Thread.__init__) was never used. This is a waste since locks use OS
primitives that are in limited supply. So the lock is deleted in
_DummyThread.__init__ .
Closes bug #1089632.

Because there's new functionality the version has been upped to 0.5.

trying to return a complete line even if a size parameter was given (see
http://www.python.org/sf/1076985). This leads to buffer overflows with long
source lines under Windows if e.g. cp1252 is used as the source encoding.
This patch reverts the behaviour of readline() to something that behaves more
like Python 2.3: If a size parameter is given, read() is called only once.
As a side effect of this, readline() now supports all types of linebreaks
supported by unicode.splitlines().
Note that the tokenizer is still broken and it's possible to provoke segfaults
(see http://www.python.org/sf/1089395).

The patch makes changes to inspect.py in two places:
* the pattern to match against functions at line 436 is
modified: lambdas should be matched even if not
preceded by whitespace, as long as "lambda" isn't part
of another word.
* the BlockFinder class is heavily modified. Changes are:
- checking for "def", "class" or "lambda" names
before setting self.started to True. Then checking the
same line for word characters after the colon (if the
colon is on that line). If so, and the line does not
end with a line continuation marker, raise EndOfBlock
immediately.
- adding self.passline to show that the line is to be
included and no more checking is necessary on that
line. Since a NEWLINE token is not generated when a
line continuation marker exists, this allows getsource
to continue with these functions even if the following
line would not be indented.
Also add a bunch of
'quite-unlikely-to-occur-in-real-life-but-working-anyway' tests.

caused by a self._input.readline() call that wasn't checking for the
NeedsMoreData marker.
msg_43.txt contains a message that illustrates the problem, when
email.message_from_*() is called. That interface uses the Parser API, which
splits reads into 8192 byte chunks. It so happens that for the test message,
the 8192 chunk falls inside a message/delivery-status, which is where in the
FeedParser the readline() call was that didn't check for NeedsMoreData.
I also added an assert to unreadline() so it'll be more evident if an attempt
to push back NeedsMoreData ever happens again.
Bump the email package version number.

As we might have expected, writing down invariants systematically exposed a

Code simplification by eliminating the unnecessary and error-prone
convolutions for the previously weird sign convention in _WorkRep().
Makes the code more understandable, more reliable, and a bit faster.
The underlying bug still exists, but also existed in 2.3.4:
import.c's load_source_module() returns NULL if
PyOS_GetLastModificationTime() returns -1, but
PyOS_GetLastModificationTime() doesn't set any exception when it returns
-1, and neither does load_source_module() when it gets back -1. This
leads to "SystemError: NULL result without error in PyObject_Call"
on an import that fails in this way.
