New submission from jan matejek [EMAIL PROTECTED]: python 2.6's compatibility socket.ssl() method does not handle 'sock' parameter in the same way. in 2.5, ssl() looked like this: def ssl(sock, keyfile=None, certfile=None): if hasattr(sock, _sock): sock = sock._sock return _realssl(sock, keyfile, certfile) in 2.6 the call is handed to ssl.sslwrap_simple, which then blindly does _ssl.sslwrap(sock._sock, 0, keyfile, certfile, CERT_NONE, PROTOCOL_SSLv23, None) instead of checking whether the sock is the socket itself or the socket object.

[issue3891] collections.deque should have empty() method
Terry J. Reedy [EMAIL PROTECTED] added the comment: I changed this to a doc issue for 2.6/3.0 whenever. I have two objections to adding An empty deque evaluates as false. First, it implies (falsely) that it could be otherwise; since deque has no __bool__ method, its __len__ method is used, so that bool(d) == (len(d)!=0). Second, it misses better doc enhancements that might make the statement I just made clearer and easier to find. 1. Ref manual Expressions Boolean Operations says In the context of Boolean operations, and also when expressions are used by control flow statements, the following values are interpreted as false: False, None, numeric zero of all types, and empty strings and containers (including strings, tuples, lists, dictionaries, sets and frozensets). For 3.0, I suggest replacing and empty strings... with empty strings and sequences (including strings, bytes, bytearrays, tuples, lists, and Userlists and deques from the collections module), and other empty containers (sets, frozensets, dictionaries, and Userdicts and defaultdicts from the collections module). Anything else I forgot? Adjust for 2.5/6. The sentence after next User-defined objects can customize their truth value by providing a __bool__() method. should say '... __bool__ or __len__ method.', with __len__ linked to object.__len__ just as __bool__ is linked to object.__bool__. 2. The LibRef entry for built-in function bool says simply Convert a value to a Boolean, using the standard truth testing procedure. Extended that with described in the Language reference in the __bool__ and __len__ entries of the Special methods subsection and in the Boolean operations subsection. -- assignee: rhettinger - georg.brandl components: +Documentation -Extension Modules, Library (Lib) nosy: +georg.brandl, tjreedy versions: +Python 2.6, Python 3.0 -Python 2.7, Python 3.1 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3891 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue3913] compound_stmt syntax includes 'decorated'
Bruce Frederiksen [EMAIL PROTECTED] added the comment: The grammar definitions in the Language Reference are _not_ just a straight copy of the Grammar. They have been reworked. (I don't know why, perhaps to make it easier to understand)? So the Grammar defines funcdef and classdef _without_ decorators and then has a separate definition for decorated funcdefs and classdefs called 'decorated' that is another compound_stmt (along with funcdef and classdef). (For Grammar, I'm looking at: http://docs.python.org/dev/3.0/reference/grammar.html). The Language Reference defines both funcdef and classdef _with_ optional decorators, so the 'decorated' alternative for compound_stmt is no longer required and should be deleted. The following links should take you straight to the funcdef and classdef definitions in the Language Reference: http://docs.python.org/dev/3.0/reference/compound_stmts.html#grammar-token-funcdef http://docs.python.org/dev/3.0/reference/compound_stmts.html#grammar-token-classdef Now, I just also noticed that the Language Reference actually has two definitions of funcdef. The second definition is 3 lines below the first one and fails to include either the optional decorators or the new [- expression] option after the argument list. Should I report this as another bug, or does this comment count. This second definition should be deleted. Also, the first definition of funcdef in the Language Reference has an extraneous '?' character after the [- expression] which should also be deleted. Should I report this as a separate bug too, or leave it, as well, to this comment? (Sorry for asking whether to report these too, I don't know how strict you guys are about keeping a record of everything). There are many other places where the grammar defined in the Language Reference is not a mirror copy of the Grammar (but is still an equivalent grammar). In fact, this seems to be the rule, rather than the exception. If you are unaware of this, you should examine the grammar definitions in the Language Reference and compare them to the Grammar yourself; or ask whoever is in charge of the Language Reference document. I don't know why this was done, I'm just trying to point out that the Language Reference document has some (minor) bugs in it that are very easily fixed.

[issue3891] collections.deque should have empty() method
Roy Smith [EMAIL PROTECTED] added the comment: I think you're missing the point. Imagine you are somebody who doesn't know Python internals. You're looking at the doc page for deque and ask yourself the question, How do I tell if one of these is empty?. There's no information ON THAT PAGE that answers that question. Your explanation is all about How do I compute the boolean value of a container? The logical gap is that you need to understand that to tell if it's empty, you should compute the boolean value. You give the page on boolean operations as part of the answer, but you need to know to go look at that page in the first place. I should be able to look at the page that describes a deque and find out everything I need to know about that class on that page. Essentially, what you're saying is that deque inherits some behaviors from container, one of which being that if you convert a container to a bool, it is True iff the container is not empty. So, there should be something on the deque page which points to that information.
