New submission from Julian <python_org(a)somethinkodd.com>:
Since Python 2.6, httplib has offered a timeout parameter for fetches. As the documentation explains, if this parameter is not provided, it uses the global default.
What the document doesn't explain is httplib builds on top of the socket library. The socket library has a default timeout of None (i.e. forever). This may be an appropriate default for general sockets, but it is a poor default for httplib; typical http clients would use a timeout in the 2-10 second range.
This problem is propagated up to urllib2, which sits on httplib, and further obscures that the default might be unsuitable.
>From an inspection of the manuals, Python 3.0.1 suffers from the same problem except, the names have changed. urllib.response sits on http.client.
I, for one, made a brutal mistake of assuming that the "global default" would be some reasonable default for fetching web pages; I didn't have any specific timeout in mind, and was happy for the library to take care of it. Several million successful http downloads later, my server application thread froze waiting forever when talking to a recalcitrant web-server. I imagine others have fallen for the same trap.
While an ideal solution would be for httplib and http.client to use a more generally acceptable default, I can see it might be far too late to make such a change without breaking existing applications. Failing that, I would recommend that the documentation for httplib, urllib, urllib2, http.client and urllib.request (+ any other similar libraries sitting on socket? FTP, SMTP?) be changed to highlight that the default global timeout, sans deliberate override, is to wait a surprisingly long time.

'naive' and 'aware' are key datetime types - they need a proper definition and anchor for crossrefences. If you take a look at http://docs.python.org/library/datetime.html - the definition of distinction between them is too vague and this seeds of uncertainty grow through the rest of the doc. It is not said how to make non-naive object, how to detect if object of naive or aware. All this stuff is very important for troubleshooting datetims issues in Python projects. It needs a proper documentation.

http://docs.python.org/library/cmd.html#
Documentation for cmd module is poor to explain the value of this module to users. Intro is too abstract - phrase "simple framework for writing line-oriented command interpreters" doesn't mean much. Perhaps word "interactive" is missing?
So, there is no part explaining the what cmd does exactly (intro fails) and no part explaining the main principle - How exactly does this framework allows to do this in a simple way? (I guess reference part under 'Cmd objects -> Cmd.cmdloop([intro]) -> p[4]` does that, but it is not the place you'd usually expect this info.
At the very least what could be done is a link to Doug's tutorial http://www.doughellmann.com/PyMOTW/cmd/

New submission from Terry J. Reedy <tjreedy(a)udel.edu>:
In 3.3. Special method names, 'object' is used as a pseudo class name to prefix all the special method entries. This conflicts with the usual two Python meanings.
1. 'object' is the name of a specific class. So the entry for object.__getattribute__(self, name) says to avoid circularity by calling
object.__getattribute__(self, name), which looks circular and requires a bit a mental work by the reader to properly understand. Ditto for
object.__setattr__(self, name, value) calling
object.__setattr__(self, name, value)
2. Non-specifically, 'object' is usually understood to mean any Python object, not just a class. But the signatures as written require that 'object' specifically be a class and 'object' does not convey that.
So for both reasons, I propose that the pseudoname 'object' be replaces with 'class' or 'someclass'

New submission from Michael Foord <michael(a)voidspace.org.uk>:
Where os.listdir encounters undecodable bytes from the filesystem it uses the surrogateescape handler. As the resulting strings are invalid they can't be encoded without an errorhandler, and so can't be printed (for example).
This should be documented.

New submission from beeNuts <jeff.adams(a)linux.com>:
Issue #14144, with the title "urllib2 HTTPRedirectHandler not forwarding POST data in redirect" was recently closed with these comments:
"This could be cookbook recipe style example, if it's utility
value is high. I am closing this issue as I feel that the requirement may not be addressed by a change. If there is patch for HowTo, we can tackle that in another issue. Thank you for contribution."
The decision that documents on this issue were preferable to a patch seems like a fair compromise, especially considering that the RFC is decidedly ambiguous.I was wondering if the HowTo would be forthcoming?
It seems to me that the value/utility would certainly be high. I'd submit it myself but I'm so new to Python that I don't trust my ability to do it correctly. It's something I would find highly useful, though.
