Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.

(Championed by Bob Ippolito.)

The update() method for mappings now accepts all the same argument forms
as the dict() constructor.  This includes item lists and/or keyword
arguments.

is too expensive on FreeBSD's KSE threading infrastructure and
even test_threadedimport fails on default setting.

* reverse order of files on the command line in pickle2db.py to make it
  symmetrical with db2pickle.py in the two-arg case (src, then dest)

are within proper boundaries as specified in the docs.

This can break possible code (datetime module needed changing, for instance)
that uses 0 for values that need to be greater 1 or greater (month, day, and
day of year).

Fixes bug #897625.

__getitem__() and __setitem__().

Simplifies the API, reduces the code size, adds flexibility, and makes
deques work with bisect.bisect(), random.shuffle(), and random.sample().

and add flag comments to ceval.c and main.c alerting people to the coupling
between pystack and the layout of those files.

* Add doctests for the examples in the library reference.
* Add two methods, left() and right(), modeled after deques in C++ STL.
* Apply the new method to asynchat.py.
* Add comparison operators to make deques more substitutable for lists.
* Replace the LookupErrors with IndexErrors to more closely match lists.

- Allow easy access to the PackMan homepage, for even more databases.

This is for compatibility with pickle.py .

float_richcompare.  Reported on c.l.py by Helmut Jarausch.

 * Fixed a bug in the compatibility interface set_location() method
   where it would not properly search to the next nearest key when
   used on BTree databases.  [SF bug id 788421]
 * Fixed a bug in the compatibility interface set_location() method
   where it could crash when looking up keys in a hash or recno
   format database due to an incorrect free().

an optimized installation problem on FreeBSD libpthread.

for MacPython 2.3 (and, hopefully, python 2.3 for windows too).

Invoke the standard error handlers for non-200 responses.

Always supply a "Connection: close" header to prevent the server from
leaving the connection open.  Downstream users of the socket may
attempt recv()/read() with no arguments, which would block if the
connection were kept open.

must at least provide the terminating NUL character.
