[issue2645] httplib throws ValueError

[Niall O'Higgins]

Niall O'Higgins <[EMAIL PROTECTED]> added the comment:

Unfortunately I do not get this consistently from any URL.  My code is
periodically polling a single HTTP server over the Internet.  Quite
possibly it is triggered by some random network/remote server condition. 

I have not had the chance to look deeply into the RFC yet.

[issue2657] curses

[Fernando Pérez]

New submission from Fernando Pérez <[EMAIL PROTECTED]>:

Curses sometimes fails to correctly initialize the terminal. 
Unfortunately I don't know how to reproduce the problem, it was reported
multiple times by ipython users, but I have no idea what causes it.  I
finally found a workaround by making a termios call that at least
restores terminal state (see attachment), but it's just a workaround,
not a real fix.

The issue manifests itself as follows: at some point (I don't know why),
a call to curses.initscr() doesn't actually set the terminal in the
usual mode where input isn't accepted, but instead the terminal
continues accepting normal input, issuing newlines, etc.  The only sign
that curses is active is that in a modern terminal, the scrollbar
changes to fill the screen.  After this, calling curses.endwin(),
instead of restoring terminal state, leaves the terminal in the mode
that typically initscr() would put it in: no input is displayed,
printouts swallow end-of-line characters, etc.

When this happened in ipython sessions, we'd just suggest users call
!reset (the system command), which would restore terminal state.  But
the problem is obviously in curses itself, because once this problem
appeared, running the attached script would always print 'False' for the
state condition checked there.

For now in IPython we have a workaround, but perhaps with this little
description/example, someone who knows the curses code might be able to
actually fix the real problem.  If I find a reliable way to trigger the
bug, I'll add comments here indicating so.

[issue2656] Autodoc should skip inherited methods

[John Millikin]

New submission from John Millikin <[EMAIL PROTECTED]>:

Using the following class layout:

class A (object):
def a (self):
"A.a"
pass
class B (A):
def b (self):
"B.b"
pass

If sphinx.ext.autodoc is used to extract documentation, the entry for
class B will have subentries for both the a() and b() methods. This is
unnecessary clutter. It would be nice if the inherited method was
skipped when documenting B, or even better if it was inserted as a
"stub" linking to the documentation for A.a().

[issue2655] Create ctypes instances from buffer interface

[Thomas Heller]

New submission from Thomas Heller <[EMAIL PROTECTED]>:

This patch implements a .from_buffer(source, offset=0) class method from
ctypes types.  'source' must expose a writeable buffer interface; the
created ctypes instance will share the internal buffer of the source
object; also it holds a reference to the source object to keep it alive.

The usual problems with the buffer interface are not hidden.

Open question:
Should there be an additional 'copy_from_buffer' class method that
accepts read-only buffer interface (as an alternative, an optional
'copy=False' parameter could be introduced)?

Yeah, it's actually still blowing up for me to. I have no idea what I

[issue2636] Regexp 2.6 (modifications to current re 2.2.2)

[Jeffrey C. Jacobs]

Jeffrey C. Jacobs <[EMAIL PROTECTED]> added the comment:

Here are the modification so far for item 9) in _sre.c plus some small
modifications to sre_constants.h which are only to get _sre.c to
compile; normally sre_constants.h is generated by sre_constants.py, so
this is not the final version of that file.  I also would have intended
to make SRE_CHARSET and SRE_COUNT use lookup tables, as well as maybe
others, but not likely any other lookup tables.  I also want to remove
alloc_pos out of the self object and make it a parameter to the ALLOC
parameter and probably get rid of the op_code attribute since it is only
used in 1 place to save one subtract in a very rare case.  But I want to
resolve the 10% problem first, so would appreciate it if people could
look at the REMOVE_SRE_MATCH_MACROS section of code and compare it to
the non-REMOVE_SRE_MATCH_MACROS version of SRE_MATCH and see if you can
suggest anything to make the former (new code) faster to get me that
elusive 10%.

[issue2651] Strings passed to KeyError do not round trip

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:

Here is another form of the same inconsistency:

>>> [].pop(0)
IndexError: pop from empty list
>>> {}.pop(0)
KeyError: 'pop(): dictionary is empty'

And my preferred one:
>>> unicodedata.lookup('"')
KeyError: 'undefined character name \'"\''

KeyError is special in that dict lookup raises the equivalent of
KeyError(key). Since the key may be any kind of (hashable) object, it's
preferable to repr() it.

I can see 3 solutions to the problem:

1- imitate IndexError for lists: the exception do not contain the key.

2- dict lookup builds the complete string message, and raise it
   raise KeyError("key not found: %r" % key)
then KeyError.__str__ can be removed.

3- like IOError, KeyError has "msg" and "key" attributes. then dict
lookup raises
   raise KeyError("key not found", key)
and KeyError.__str__ is something like:
   if self.key is not None:
   return "%s: %r" % (self.msg, self.key)
   else
   return str(self.msg)

Choice 1 is not an improvement.
Choice 2 has the correct behavior but leads to performance problems;
KeyErrors are very very common in the interpreter (namespace lookups...)
and formatting the message is costly.
Choice 3 may cause regression for code that use exception.args[0], but
otherwise seems the best to me. I'll try to come with a patch.

Sure, why not ?

I think you have to ask another question: Is repr() allowed to
return a string (instead of Unicode) in Py3k ?

If not, then unicode_repr() will have to check the return value of
the codec and convert it back to Unicode as necessary.

> I started to think codec is not nessesary, but python function is enough.

That's what we currently have with unicode_repr(), but it doesn't
solve the problem.

To perform exact base-10 calculation, you may use the Decimal module.
Or use round() instead of the int() truncation.
