created by Andrew's setup.py script, *if* we're actually running from
the build directory. (The test for that: whether the sys.path[-1]
ends in "/Modules".)
This has one disadvantage: it imports a fair amount of code from the
distutils package, just in order to be able to calculate the correct
pathname. See if I care. :-)
del'ing func.func_dict. I took the opportunity to also clean up some
other nits with the code, namely core dumps when del'ing func_defaults
and KeyError instead of AttributeError when del'ing a non-existant
function attribute.
Specifically,
func_memberlist: Move func_dict and __dict__ into here instead of
special casing them in the setattro and getattro methods. I don't
remember why I took them out of here before I first uploaded the PEP
232 patch. :/
func_getattro(): No need to special case __dict__/func_dict since
their now in the func_memberlist and PyMember_Get() should Do The
Right Thing (i.e. transforms NULL values into Py_None).
func_setattro(): Document the intended behavior of del'ing or setting
to None one of the special func_* attributes. I.e.:
func_code - can only be set to a code object. It can't be del'd
or set to None.
func_defaults - can be del'd. Can only be set to None or a tuple.
func_dict - can be del'd. Can only be set to None or a
dictionary.
Fix core dumps and incorrect exceptions as described above. Also, if
we're del'ing an arbitrary function attribute but func_dict is NULL,
don't create func_dict before discovering that we'll get an
AttributeError anyway.
(I realize that I didn't really test this, because all the tests
succeed, so verify() never raised an AssertionError -- but the test
suite still succeeds, so I'm not too worried.)
This patch adds support for Cygwin to util.get_platform(). A Cygwin
specific case is needed due to the format of Cygwin's uname command,
which contains '/' characters.

I agree, so am fixing this.
symbol table for each top-level compilation unit. The information in
the symbol table allows the elimination of the later optimize() pass;
the bytecode generation emits the correct opcodes.
The current version passes the complete regression test, but may still
contain some bugs. It's a fairly substantial revision. The current
code adds an assert() and a test that may lead to a Py_FatalError().
I expect to remove these before 2.1 beta 1.
The symbol table (struct symtable) is described in comments in the
code.
The changes affects the several com_XXX() functions that were used to
emit LOAD_NAME and its ilk. The primary interface for this bytecode
is now com_addop_varname() which takes a kind and a name, where kind
is one of VAR_LOAD, VAR_STORE, or VAR_DELETE.
There are many other smaller changes:
- The name mangling code is no longer contained in ifdefs. There are
two functions that expose the mangling logical: com_mangle() and
symtable_mangle().
- The com_error() function can accept NULL for its first argument;
this is useful with is_constant_false() is called during symbol
table generation.
- The loop index names used by list comprehensions have been changed
from __1__ to [1], so that they can not be accessed by Python code.
- in com_funcdef(), com_argdefs() is now called before the body of the
function is compiled. This provides consistency with com_lambdef()
and symtable_funcdef().
- Helpers do_pad(), dump(), and DUMP() are added to aid in debugging
the compiler.
Also fixes two long-standing bugs (present in 2.0):
1. .join() didn't check that the result size fit in an int.
2. string.join(s) when len(s)==1 returned s[0] regardless of s[0]'s
type; e.g., "".join([3]) returned 3 (overly optimistic optimization).
I resisted a keen temptation to make .join() apply str() automagically.

The socketserver code, with a little bit of tweaking, can be made
sufficiently general to service "requests" of any kind, not just by sockets.
The BaseServer class was created, for example, to poll a table in a MYSQL
database every 2 seconds. each entry in the table can be allocated a
Handler which deals with the entry.
With this patch, using BaseServer and ThreadedServer classes, the creation
of the server that reads and handles MySQL table entries instead of a
socket was utterly trivial: about 50 lines of python code.
You may consider this code to be utterly useless [why would anyone else
want to do anything like this???] - you are entitled to your opinion. if you
think so, then think of this: have you considered how to cleanly add SSL to
the TCPSocketServer? What about using shared memory as the
communications mechanism for a server, instead of sockets? What about
communication using files?
The SocketServer code is extremely good every useful. it's just that as it
stands, it is tied to sockets, which is not as useful.
I heartily approve of this idea.
