[issue5036] xml.parsers.expat make a dictionary which keys are broken if buffer_text is False.

[HiroakiKawai]

HiroakiKawai  added the comment:

The sample code has bug. expat is OK.

Method char_data must append the incoming characters because the 
character sequence is an buffered input.
  def char_data(self, data):
self.data += data

You should reset it by self.data = '' at end_element().

[issue5040] Bug of CGIXMLRPCRequestHandler

[Wayne Huang]

New submission from Wayne Huang :

I met a bug of CGIXMLRPCRequestHandler in Python3.0. Because of the bug,
I couldn't use RPC in Apache CGI.

The version of my Python 3.0 is "Python 3.0 (r30:67507, Dec  3 2008,
20:14:27) [MSC v.1500 32 bit (Intel)] win32".

The code of my client is follow.

s = xmlrpc.client.ServerProxy('http://localhost/cgi-bin/rpc.py')
print(s.system.listMethods())

The code of my server in Apache's cgi-bin is follow

#!C:/Python30/python.exe

from xmlrpc.server import *

handler=CGIXMLRPCRequestHandler()
handler.register_introspection_functions()
handler.handle_request()

When I run the client code,some error of parser raise.

I found it is the matter of 'Content-Length' in the HTTP Response of
CGIXMLRPCRequestHandler,it is a wrong number.

I just saw this same test_kqueue failure pop up on the OS X 3.x buildbot,
so it's evidently not just a peculiarity of my machine.

Unless there are any objections, I'll go ahead and check this in:  I think 
it's a sufficiently trivial fix that it's not worth wasting Christian's 
time with. :)

Laca> If I read it correctly, on OS X, you will need to use -h instead

We can worm around that using configure.  Thanks for the reference.  That

[issue5037] unicode(x) for weakref.proxy objects invokes __str__ instead of __unicode__

[Nick Coghlan]

Nick Coghlan  added the comment:

weakref.proxy needs to be fixed to delegate the unicode slot correctly.

>>> from weakref import proxy
>>> "__unicode__" in dir(type(proxy(Exception)))
False

That predicate must return true in order for the delegation to do the
right thing (this is actually the case for all of the slots and
pseudo-slots that can bypass __getattribute__ on the instance object -
it's just that most of them are already handled correctly).

This need to explicitly delegate all supported slots is the reason why
weakref proxy instances add so many magic method stubs when compared to
the actual interface of the underlying class:

>>> len(set(dir(type(proxy(Exception - set(dir(Exception)))
53

[issue5042] Structure sub-subclass does not initialize with base class positional arguments

[Jason R. Coombs]

New submission from Jason R. Coombs :

When trying to create a sub-subclass of a ctypes.Structure, the behavior
is not as expected.

An executable example that describes the problem in detail and
demonstrates the issue is available at
http://paste.turbogears.org/paste/29555 and also attached.

The failing behavior is near the beginning, following the description.

Three unsuccessful workarounds follow.

The expected behavior is found at the end, where a final workaround has
been implemented.

Can this behavior be improved in subsequent releases of ctypes?  If not,
can ctypes at least support the workaround natively (perhaps by
providing a method in the Structure class that performs the workaround
and can be called by a sub-subclass during __init__)?

My comment on this part of code is( from issue3871): 
+# FIXME: next code is from issue870382

+# Linking to a different library without to specify correct runtime
+# version for the headers will link renamed functions to msvcrt.
+# See issue3308: this piece of code is python problem even
+# with correct w32api headers.
+# Issue: for MSVC compiler we can get the version and from version

+# Output of sys.version is information for python build on first

[issue4676] python3 closes + home keys

[Weeble]

Weeble  added the comment:

I have experienced similar problems in Python 2.6.1 on Windows, and
found them to be due to Tk 8.5. I posted my findings here:

http://mail.python.org/pipermail/idle-dev/2009-January/002738.html

In summary, Tk 8.5 changed the name of the "anchor" mark to be unique to
each Text widget. The code to make the home key toggle between column 0
and the start of the text tries to make use of the "anchor" mark and
gets confused.

In the email I proposed a simple fix which I'm testing out right now.
Should I attach it as a patch?

[issue2527] Pass a namespace to timeit

[David W. Lambert]

David W. Lambert  added the comment:

This note is simply a reminder that Antoine's 'from __main__ import *' 
solution fails in python3.  Also, resolution of this issue probably 
could incorporate Issue1397474.


>>> import timeit
>>> timeit.timeit('None','from __main__ import *')
Traceback (most recent call last):
  File "", line 1, in

[issue4676] python3 closes + home keys

[Weeble]

Weeble  added the comment:

Another complication. On Windows, this line doesn't do what it claims:

if (event.state & 12) != 0 and event.keysym == "Home":
# state&1==shift, state&4==control, state&8==alt
return # ; fall back to class binding

The comment says state&8==alt, but this is wrong. state&8==mod1, and on
Windows Tk defines mod1 to be num-lock. So if you have num-lock on,
home_callback will always fall back to the standard binding.

See the Tk source:
xlib/X11/X.h   defines Mod1Mask
win/tkWinX.c   maps VK_NUMLOCK to Mod1Mask

[issue3657] pickle can pickle the wrong function

[Mark Dickinson]

Mark Dickinson  added the comment:

I just committed Tim's suggested change in r68906.  This seemed a no-
brainer, regardless of what should be done about pickle.whichmodule.  One 
fewer sporadic buildbot failure sounds like a good thing to me.

(I hadn't noticed the pickletools failures until just after I committed a 
pickle module change, so I was rather thrown until Antoine directed me 
here...)

[issue5045] imaplib should remove length of literal strings

[Branden Moore]

New submission from Branden Moore :

IMAP Literals are a tricky subject.  Currently, if IMAP returns:

* text text text {5}\r\n
12345more text

imaplib will return 2 data items:
[("text text text {5}", '12345'), "more text"]

This forces users of imaplib to then parse out and remove the '{5}' from
the first part of the tuple before appending the literal string.  It
would be nice to have imaplib strip the '{size}' portion of the string
in the first part of the tuple, so that the return value would be:
[("text text text ", '12345'), "more text"]

Though, because this entire response from the IMAP server should be
interpreted as a single line, it would be even better to return a
response such that 'data' is:
[(("text text text ", '12345'), "more text")]

a.k.a., a single 'data' item (only one IMAP response per data item) that
contains either a string or a tuple.  The tuple will contain either more
tuples and/or more strings.  Each sub-tuple here would contain two
strings, text, and the IMAP Literal String.

This would make parsing the responses from imaplib much more simple.  It
demarks obviously where IMAP Literal Strings are, and doesn't require
additional string parsing on the side of the imaplib user.

Thanks!

[issue5046] native win32 and wine mingw+msys build of python2.7

[Luke Kenneth Casson Leighton]

New submission from Luke Kenneth Casson Leighton :

this is an update of the mingw+msys port for native win32,
with the aim of being both compiled and used under both
wine-win32 and native-win32.

it is not a cross-compile patch.  it does not require -lwine.
it does not require a unix system.  it does not require cygwin.
(repeat the previous four sentences for both build _and_ use
of the resultant python.exe).  this information is specifically
given and stated [so blandly] because several people have been
extremely confused by what this patch achieves, due to the
tools being utilised to achieve it [wine].

the patch is against svn trunk r68884.

as of 2 hours ago, the following tests failed:
22 tests failed:
test_cmath test_cmd_line_script test_compiler test_ctypes
test_decimal test_distutils test_file test_logging test_mailbox
test_math test_ntpath test_os test_parser test_posixpath test_pwd
test_smtplib test_startfile test_tempfile test_transformer
test_winsound test_zipfile test_zipimport_support

since then, several have been corrected.  test_pwd should not be
being tested.  several of the tests (test_tempfile) are fails due
to use of native wine msvcrt (it gets better when win32 msvcrt
is used).

this is work-in-progress for those people interested.

builds with --enable-msvcr9build are possible.

incorporation of roumen's cross-compile work is ongoing.

[issue5047] Remove Monterey support from configure.in

[Skip Montanaro]

New submission from Skip Montanaro :

The attached patch removes vestiges of Monterey compiler support from
configure.in.  Apparently Monterey was some ill-conceived 64-bit SCO/IBM
operating system which died in 2000.  Can't see why we need to support it.

[issue5034] itertools.fixlen

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Am still leaning towards rejecting this one based on:
* paucity of use cases
* non-atomicity (it can be built-out of existing tools)
* minimizing the number of tools in the toolkit
* not convinced that padded tuple unpacking is desirable

[issue4753] Faster opcode dispatch on gcc

[Jeffrey Yasskin]

Jeffrey Yasskin  added the comment:

In the comment, you might mention both -fno-crossjumping and -fno-gcse.
-fno-crossjumping's description looks like it ought to prevent combining
computed gotos, but
http://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/Optimize-Options.html says
-fno-gcse actually does it, and in my brief tests, the manual is
actually correct (compiling with just -fno-crossjumping combined gotos
anyway).

Otherwise, threadedceval6.patch looks good to submit to me.

[issue5048] Extending itertools.combinations

[Konrad]

New submission from Konrad :

The function itertools.combinations might benefit from making
the 'r' (length of the combinations) argument optionally a sequence.

With that change one could call combinations(sequence, [2, 3]) in
order to get all combinations of length 2 and 3.
In particular, one could call combinations(sequence,
range(len(sequence)) in order to get *all* combinations of given
sequence.

The change would be backwards compatible as it would check for
sequential arguments.

[issue5049] ctypes unwilling to allow pickling wide character array

[Jason R. Coombs]

New submission from Jason R. Coombs :

Using Python 2.6.1, I'm unable to pickle a simple object with an array
of wide characters.

import ctypes, pickle

class MyStruct(ctypes.Structure):
  _fields_ = [('name', ctypes.c_wchar*2)]

s = MyStruct('DC')

pickle.dumps(s) # raises ValueError.

Replace ctypes.c_wchar with ctypes.c_char and the pickling works fine.

[issue5048] Extending itertools.combinations

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Do you have compelling use cases?

Is it worth what it takes to preserve the relation with permuations()
and product() and the lexicographic orderings?

Do we care the length of the output is no longer predictable by a simple
n! / r! / (n-r)!  ?

Do we care that the variable length output prevents uses in for-loops
with tuple unpacking:

   for a, b, c in combinations('ABCDEF', [2,3]):
. . .

[issue5050] unicode(C) invokes C.__unicode__ when __unicode__ is defined

[Yu-Jie Lin]

New submission from Yu-Jie Lin :

Run the following code

class A:
  def __str__(self):
return "__str__"
  def __unicode__(self):
return "__unicode__"

a = A()

print str(a), unicode(a)
print str(A), unicode(A)



Results on Python 2.5.4 (r254:67916):
__str__ __unicode__
__main__.A
Traceback (most recent call last):
  File "/home/livibetter/tmp/unicode_classobj.py", line 14, in 
print str(A), unicode(A)
TypeError: unbound method __unicode__() must be called with A instance
as first argument (got nothing instead)

Results on Python 2.6.1 (r261:67515):
__str__ __unicode__
__main__.A __main__.A



I was expecting the same result as on 2.6.1. By my observation,
unicode(C) tries to invoke C.__unicode__ if __unicode__ is defined in C,
where C is a class object.

I believe this behavior is incorrect.

[issue5048] Extending itertools.combinations

[Ezio Melotti]

Ezio Melotti  added the comment:

It would also be nice to have a __len__ method on both permutations and
combinations.

len(permutations(sequence)) could return the number of permutations
using the formulas (e.g. n! for permutations) without generating all the
possible permutations (as opposed to something like
len(list(permutations(sequence.

Also, is there a way to calculate combinations with repetitions[1]?
Maybe we could add an optional argument repetitions=True/False.

[issue5048] Extending itertools.combinations

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Guido disallowed returning a len method on iterators.  He expected
bool(it) to be False.

The recipes section of the itertools docs has code for
combinations_with_replacement().  It was not included originally because
it was unclear whether there was actually a need to generate them. 
Possibly, people are mainly interested in knowing how many there are but
having no need to actually enumerate them.  That being said, if I get
more requests or if some real world use cases arise, I would be happy to
C the recipe and add it in Py2.7.
