Here's a patch for the ForkingMixIn which will prevent the server from
forking itself into the ground. Note: I've tested a very similar patch
(subclassed ForkingMixIn) but not actually tested this one. As you might
surmise, this was done out of necessity...
If the maximum number of children are already running, block while waiting
for a child to exit.

(I added that last sentence as a comment to the code --GvR.)
for gotonext() pushing self.pos past the end of the string. This can
happen if the message has a To field like "To: :" and you call
msg.getaddrlist('to').
In splithost, accept empty host part in URLs. This is required for
file URLs that can have an empty host part. For such URLs, we should
not return the initial 2 slashes as part of the file name.
1. Fix incorrect file open mode on Win32 platforms (use "rb" instead
of "r").
2. Add shallow parameter to cmp.cmp(). If false, deep file
comparisons are made.
The module should be 100 percent backwards compatible.
Urllib makes the URL of the opened file available through the geturl
method of the returned object. For local files, this consists of
file: plus the name of the file. This results in an invalid URL if
the file name was relative. This patch fixes this so that the
returned URL is just a relative URL in that case. When the file name
is absolute, the URL returned is of the form file:///absolute/path.
[I guess that a URL of the form "file:foo.html" is illegal... GvR]
Introduce a new builtin exception, UnboundLocalError, raised when ceval.c
tries to retrieve or delete a local name that isn't bound to a value.
Currently raises NameError, which makes this behavior a FAQ since the same
error is raised for "missing" global names too: when the user has a global
of the same name as the unbound local, NameError makes no sense to them.
Even in the absence of shadowing, knowing whether a bogus name is local or
global is a real aid to quick understanding.
Example:
D:\src\PCbuild>type local.py
x = 42
def f():
print x
x = 13
return x
f()
D:\src\PCbuild>python local.py
Traceback (innermost last):
File "local.py", line 8, in ?
f()
File "local.py", line 4, in f
print x
UnboundLocalError: x
D:\src\PCbuild>
Note that UnboundLocalError is a subclass of NameError, for compatibility
with existing class-exception code that may be trying to catch this as a
NameError. Unfortunately, I see no way to make this wholly compatible
with -X (see comments in bltinmodule.c): under -X, [UnboundLocalError
is an alias for NameError --GvR].
[The ceval.c patch differs slightly from the second version that Tim
submitted; I decided not to raise UnboundLocalError for DELETE_NAME,
only for DELETE_LOCAL. DELETE_NAME is only generated at the module
level, and since at that level a NameError is raised for referencing
an undefined name, it should also be raised for deleting one.]
