Also clarified docs (official and docstring) that the value from gethostname()
is returned if gethostbyaddr() doesn't do the job.
* 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.

Adjust doc(object) to display useful documentation for plain values (e.g.

`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__ .

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

Code simplification by eliminating the unnecessary and error-prone

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.

Turns out the mysterious "expected output" file contained exactly N dots,
because test_poll() has a loop that *usually* went around N times,
printing one dot on each loop trip. But there's no guarantee of that,
because the exact value of N depended on the vagaries of scheduling
time.sleep()s across two different processes. So stopped printing dots,
and got rid of the expected output file. Add a loop counter instead,
and verify that the loop goes around at least a couple of times. Also

Bug fixes:
* Use fresh copy of globals/locals so the script being debugged can't access
the pdb namespace (e.g.: p line_prefix will no longer work).
* Remove pdb.py's path from sys.path. Having it in there is normally not a
problem, but it could prove irritating when messing with PYTHONPATH or
invoking pdb via /usr/bin/pdf.
* You can now set a breakpoint on the script being debugged, even if the script
doesn't end with a '.py' extension. Also, setting breakpoints with absolute
paths now works reliably.
Enhancements:
* Go directly to the first line of the script.
* Enter post-mortem debugging if the script being debugged doesn't catch an
exception.
* Restart the script being debugged and preserve debugger state when the script
being debugged exits.
Cleanup:
* Moved the __main__ method into a main() function.
* Kill the (undocumented, not in __all__) mainmodule/mainpyfile globals, add a
mainpyfile attribute to pdb.

The shutils.rmtree() implementation uses an excessive amount of memory when
deleting large directory hierarchies. Before actually deleting any files, it

Briefly (from the NEWS file):
- Updates for the email package:
+ All deprecated APIs that in email 2.x issued warnings have been removed:
_encoder argument to the MIMEText constructor, Message.add_payload(),
Utils.dump_address_pair(), Utils.decode(), Utils.encode()
+ New deprecations: Generator.__call__(), Message.get_type(),
Message.get_main_type(), Message.get_subtype(), the 'strict' argument to
the Parser constructor. These will be removed in email 3.1.
+ Support for Python earlier than 2.3 has been removed (see PEP 291).
+ All defect classes have been renamed to end in 'Defect'.
+ Some FeedParser fixes; also a MultipartInvariantViolationDefect will be
added to messages that claim to be multipart but really aren't.
+ Updates to documentation.
deque_item(): a performance bug: the linked list of blocks was followed
from the left in most cases, because the test (i < (deque->len >> 1)) was
after "i %= BLOCKLEN".
deque_clear(): replaced a call to deque_len() with deque->len; not sure what
this call was here for, nor if all compilers under the sun would inline it.
deque_traverse(): I belive that it could be called by the GC when the deque
has leftblock==rightblock==NULL, because it is tracked before the first block
is allocated (though closely before). Still, a C extension module subclassing
deque could provide its own tp_alloc that could trigger a GC collection after
the PyObject_GC_Track()...
deque_richcompare(): rewrote to cleanly check for end-of-iterations instead of
relying on deque.__iter__().next() to succeed exactly len(deque) times -- an
assumption which can break if deques are subclassed. Added a test.
I wonder if the length should be explicitely bounded to INT_MAX, with
OverflowErrors, as in listobject.c. On 64-bit machines, adding more than
INT_MAX in the deque will result in trouble. (Note to anyone/me fixing
this: carefully check for overflows if len is close to INT_MAX in the
following functions: deque_rotate(), deque_item(), deque_ass_item())
request. Tim says that "correct 'fuzzy' comparison of floats cannot
be automated." (The motivation behind adding the new option
was verifying interactive examples in Python's latex documentation;
several such examples use numbers that don't print consistently on
different platforms.)
Also, add a testcase.
Formerly, the list_extend() code used several local variables to remember
its state across iterations. Since an iteration could call arbitrary
Python code, it was possible for the list state to be changed. The new
code uses dynamic structure references instead of C locals. So, they
are always up-to-date.
After list_resize() is called, its size has been updated but the new
cells are filled with NULLs. These needed to be filled before arbitrary
iteration code was called; otherwise, that code could attempt to modify
a list that was in a semi-invalid state. The solution was to change
the ob->size field back to a value reflecting the actual number of valid
cells.

* Documented that the compiled re methods are supposed to be more full
featured than their simpilified function counterparts.
* Documented the existing start and stop position arguments for the
findall() and finditer() methods of compiled regular expression objects.
* Added an optional flags argument to the re.findall() and re.finditer()
functions. This aligns their API with that for re.search() and
re.match().
When an integer is compared to a float now, the int isn't coerced to float.
This avoids spurious overflow exceptions and insane results. This should
compute correct results, without raising spurious exceptions, in all cases
now -- although I expect that what happens when an int/long is compared to
a NaN is still a platform accident.
Note that we had potential problems here even with "short" ints, on boxes
where sizeof(long)==8. There's #ifdef'ed code here to handle that, but
I can't test it as intended. I tested it by changing the #ifdef to
trigger on my 32-bit box instead.
I suppose this is a bugfix candidate, but I won't backport it. It's
long-winded (for speed) and messy (because the problem is messy). Note
that this also depends on a previous 2.4 patch that introduced
_Py_SwappedOp[] as an extern.

of the Template.delimiter attribute, we make use of the delimiter in the
escaped group, and in the safe_substitute() method more robust.
Now, .delimiter should be the unescaped delimiter literal, e.g. '$' or '&', or
whatever. The _TemplateMetaclass will re.escape() this value when it builds
the pattern.
* The parameterization of "delimiter" was incomplete.
* safe_substitute's code for braced delimiters should only be executed
when braced is not None.
* Invalid pattern group names now raise a ValueError. Formerly, the
convert code would fall off the end and improperly return None.
Beefed-up tests.
