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.]
always lowercasing the option name, call a method optionxform() which
can be overridden. Also make the regexps SECTRE and OPTRE non-private
variables so they can also be overridden.
mode attribute of the file object (if it has one), otherwise
use 'rb'.
The documentation should still show this as required until
there's a new release.
Added support for unseekable files.
(I use unqualified excepts since we don't know why the seek/tell might
fail. In my case it was because of an AttributeError.)
Problem: rfc822.py in 1.5.2 final loses the quotes around
quoted local-part names.
The fix is to preserve the quotes around a local-part
name in an address.
Test:
import rfc822
a = rfc822.AddrlistClass('(Comment stuff) "Quoted
name"@somewhere.com')
a.getaddrlist()
The correct result is:
[('Comment stuff', '"Quoted name"@somewhere.com')]
Hammond: record top-level functions (as Function instances, a simple
subclass of Class). You must use the new interface readmodule_ex() to
get these, though.
__init__.py it isn't read. (Sjoerd just came up with this, so it's
not heavily tested.)
Other (yet unsolved) package problems noted by Sjoerd:
- If you have a package and a module inside that or another package
with the same name, module caching doesn't work properly since the
key is the base name of the module/package.
- The only entry that is returned when you readmodule a package is a
__path__ whose value is a list which confuses certain class browsers
that I wrote. (Hm, this could be construed as a feature.)
I've found two places where smtplib.py sends an extra trailing space
on command lines to the SMTP server. I don't know if this ever causes
any problems, but I'd prefer to be on the safe side. The enclosed
patch removes the extra space.
all processing instruction target names containing 'xml' were
rejected, instead (as the standard rejects) only the name 'xml' itself
(or case variants thereof).
I guess in 1.5.2 a new module, whichdb, was added that attempts to
divine the nature of a database file. This module doesn't know anything
about Berkeley DB v2 files. In v2, Sleepycat added a 12-byte null pad
in front of the old magic numbers (at least for hash and btree files).
I've been using v2 for awhile and upgrading to 1.5.2 broke all my
anydbm.open calls. I believe the following patch corrects the problem.
appreciably. Triple-quoted strings no longer confuse it, nor nested
classes or defs, nor comments starting in column 1. Chews thru
Tkinter.py in < 3 seconds for me; doctest.py no longer confuses it; no
longer missing methods in PyShell.py; etc. Also captures defs
starting in column 1 now, but ignores them; an interface should be
added so that IDLE's class browser can show the top-level functions
too.
'install_site_lib' and install_site_platlib' on non-POSIX platforms.
Should at least work for NT, as this is adopted from Amos Latteier's NT
patches. Also added extensive comments bitching about the inadequacy of
the current model, both under POSIX and NT (and probably other) systems.
'run_command()' to refer to it before attempting to run a command --
that way, command classes can freely invoke other commands without fear
of duplicate execution.
Beefed up some comments and docstrings.
It wasn't hard to speed pyclbr by a factor of 3, and I'll attach an
experimental patch for that (experimental because barely tested). Uncomment
the new "String" stuff and it will deal with strings correctly (pyclbr
currently ignores the possibility), but that slows it down a lot. Still
faster in the end than current pyclbr, but-- frankly --I'd rather have the
dramatic speedup!
content-type to application/x-www-form-urlencoded only when the method
is POST. Ditto for when the content-type is unrecognized -- only
fall back to urlencoded with POST.
I noticed while watching (with lsof) my forking SocketServer app running
that I would get multiple processes listening to the socket. For the most
part, this doesn't hurt things, but if you terminate the server, this can
prevent it from restarting because it cannot bind to the port due to any
running children which also have the socket open. The following one-liner
fixes this.
meaningful return values: respectively, whether the copy was done, and
the list of files that were copied. This meant some trivial changes in
core.py as well: the Command methods that mirror 'copy_file()' and
'copy_tree()' have to pass on their return values.
of the 'install_py' command rather than 'build_py'. Obviously, this
meant that the 'build_py' and 'install_py' modules had to change; less
obviously, so did 'install' and 'build', since these higher-level
commands must make options available to control the lower-level
commands, and some compilation-related options had to migrate with the
code.
(1) Fix reference to pwd.error to be KeyError -- there is no pwd.error
and pwd.getpwnam() raises KeyError on failure.
(2) Add cookie support, by placing the 'Cookie:' header, if present,
in the HTTP_COOKIE environment variable.
Two problems: The SMTPRecipientsRefused class should not inherit
SMTPResponseException, since it doesn't provide the smtp_code and
smtp_error attributes. My patch for not adding an extra CRLF was
apparently forgotten. The enclosed patch fixes these two problems.
terminated; this makes the final assert in the self-test code fail if
the parent runs faster than the children. Fix this by calling wait()
on the remaining children instead.
