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

[Takeshi Matsuyama]

New submission from Takeshi Matsuyama :

When I make a dictionary by parsing "legacy-icon-mapping.xml"(which is a
part of
icon-naming-utils[http://tango.freedesktop.org/Tango_Icon_Library]) with
the following script, the three keys of the dictionary are collapsed if
the "buffer_text" attribute is False.

=
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from __future__ import with_statement
import sys
from xml.parsers.expat import ParserCreate
import codecs

class Database:
  """Make a dictionary which is accessible by Databese.dict"""
  def __init__(self, buffer_text):
self.cnt = None
self.name = None
self.data = None
self.dict = {}
p = ParserCreate()
p.buffer_text = buffer_text

p.StartElementHandler = self.start_element
p.EndElementHandler = self.end_element
p.CharacterDataHandler = self.char_data

with open("/usr/share/icon-naming-utils/legacy-icon-mapping.xml",
'r') as f:
  p.ParseFile(f)

  def start_element(self, name, attrs):
if name == 'context':
  self.cnt = attrs["dir"]
if name == 'icon':
  self.name = attrs["name"]
  
  def end_element(self, name):
if name == 'link':
  self.dict[self.data] = (self.cnt, self.name)

  def char_data(self, data):
self.data = data.strip()

def print_set(aset):
  for e in aset:
print '\t' + e

if __name__ == '__main__':
  sys.stdout = codecs.getwriter('utf_8')(sys.stdout)
  map_false_dict = Database(False).dict
  map_true_dict = Database(True).dict
  print "The keys which exist if buffer_text=False but don't exist if
buffer_text=True are"
  print_set(set(map_false_dict.keys()) - set(map_true_dict.keys()))
  print "The keys which exist if buffer_text=True but don't exist if
buffer_text=False are"
  print_set(set(map_true_dict.keys()) - set(map_false_dict.keys()))
=

The result of running this script is
==
The keys which exist if buffer_text=False but don't exist if
buffer_text=True are
rt-descending
ock_text_right
lc
The keys which exist if buffer_text=True but don't exist if
buffer_text=False are
stock_text_right
gnome-mime-application-vnd.stardivision.calc
gtk-sort-descending
==
I confirmed it in Python-2.5.2 on Fedora 10.

[issue4999] multiprocessing.Queue does not order objects

[Jesse Noller]

Jesse Noller  added the comment:

On a put to the queue, the object is appended onto a deque (self._buffer) 
- this buffer is managed by a thread (_start_thread) which is handed the 
_feed method as the target. I suspect the bug is actually in the _feed 
method.

[issue4111] Add DTrace probes

[Skip Montanaro]

Skip Montanaro  added the comment:

me> I get an error later running dtrace which I have yet to investigate.

Apple's dtrace program doesn't support the -G flag.  When I remove it from
Makefile.pre.in and rebuild I get an error about privileges:

dtrace -o Python/dtrace.o  -C -s ./Python/python.d Python/ceval.o
dtrace: failed to initialize dtrace: DTrace requires additional privileges

I tried adding "sudo" to the dtrace command.  Then it prompts for my
password and emits this error:

sudo dtrace -o Python/dtrace.o  -C -s ./Python/python.d Python/ceval.o
Password:
dtrace: failed to compile script ./Python/python.d: line 11: extraneous 
argument 'Python/ceval.o' ($1 is not referenced)

I'm not sure what to do at this point.  I'm not really a dtrace person.
Perhaps the Apple and Sun dtrace experts can offer a way out of this little
corner.

[issue4972] let's equip ftplib.FTP with __enter__ and __exit__

[Giampaolo Rodola']

Giampaolo Rodola'  added the comment:

As for ftplib patch you should make sure that close() gets called in any
case but never more than once.
You can use "finally" to satisfy the first requirement and "self.sock is
not None" to check the second condition:



+def __exit__(self, *args):
+"""Context management protocol.
+
+Will try to quit() if active, then close().
+If not active, a simple close() call is made.
+"""
+if self.sock is not None and self.getwelcome() is not None:
+try:
+self.quit()
+except socket.error, e:
+# [Errno 61] is Connection refused
+# if the error is different, we want to raise it.
+if e.errno != 61:
+raise
+finally:
+if self.sock is not None:
+self.close()
+else:
+self.close()

[issue4999] multiprocessing.Queue does not order objects

[Antoine Pitrou]

Antoine Pitrou  added the comment:

That's why I was suggesting to leave Queue as it is and provide a
separate PriorityQueue. With a PriorityQueue the user is free to put
(timestamp, object) tuples in it if he wants a strict chronologic
ordering. He can also use sequence numbers instead of timestamps, etc.

[issue4111] Add DTrace probes

[Skip Montanaro]

Skip Montanaro  added the comment:

After applying the patch and reconfiguring I get compilation errors in
Python/ceval.c.  I suspect it's because there is a new header file,
Python/python.h.  That's probably found by the #include directive in
favor of Include/Python.h because of the Mac's case-insensitive file
system.  Changing the Makefile targets and actions so it's named
python-dtrace.h seems to work a bit better.  I get an error later
running dtrace which I have yet to investigate.

[issue5032] itertools.count step

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Am not too excited about this one.  As a heavy itertools user myself,
I've never had occasion to need a step argument.  As an implementer, I'm
aware that it would make the code for count() much more complex (because
of the internal optimizations and because step can be positive,
negative, or zero).

Have you had any real world use cases where count(start, step) would
have been the best solution?

[issue5034] itertools.fixlen

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Am taking this under advisement but am initially disinclined.  It is not
a basic itertool since it can be composed from the others.  Also, it's
use cases seem to be few.  One challenge for the module is that adding
more tools makes the overall toolkit harder to use because the number of
choices is increased.

[issue5034] itertools.fixlen

[Antoine Pitrou]

Antoine Pitrou  added the comment:

"Return an iterator fixing *iterable*\ 's length to *length* by either
cutting elements off or adding *value* to the iterable."

Rather than mixing both, it would be more flexible to have a separate
function for each IMO.
Cutting off is already be handled by islice() (isn't it?), and padding
should be done with a function called e.g. pad() or rpad().

[issue4944] os.fsync() doesn't work as expect in Windows

[Javen Wang]

Javen Wang  added the comment:

I don't have Python2.6 installed. I just have ever read a bench article
comparing the performance between different version of Python, including
2.5, 2.6 and 3.0. That article shows, for the same script, Python2.6 has
longer running time than Python2.5. My application is a build system and
the users are very care about the time spent in build. That's why I have
the performance concern.

What concerns me more is the stdout/stderr redirection. Python2.6 manual
says they cannot be redirected if close_fds is set to True. My
application relies on the I/O redirection to control the screen output
from subprocess.

Actually I have had a work-around for this issue. It works very well so
far. I reported a bug here just because I want the Python to be better.
I learned it one year ago but I love this language. I just hope nobody
else encounter such problem again. If you guys think it won't be fixed
in Python 2.5 or has been fixed in Python 2.6, it's OK to close this
tracker. Thanks for your time.

[issue5033] setup.py crashes if sqlite version contains 'beta'

[blahblahwhat]

New submission from blahblahwhat :

When I try to 'make' Python 2.6.1:

Traceback (most recent call last):
  File "./setup.py", line 1880, in 
main()
  File "./setup.py", line 1875, in main

for x in sqlite_version.split(".")])
ValueError: invalid literal for int() with base 10: '1beta'

This was solved by replacing

  m = re.search(r'\s*.*#\s*.*define\s.*SQLITE_VERSION\W*"(.*)"', incf)

with

  m = re.search(r'\s*.*#\s*.*define\s.*SQLITE_VERSION\W*"([\d\.]*)"', 
incf)

on line 911

Here is a patch that should fix the problem. It uses Vista's
GetFinalPathNameByHandleW to expand symbolic links before passing the
path to Tcl.

[issue5032] itertools.count step

[steve21]

New submission from steve21 :

I'd like to request a 'step' argument be added for itertools.count. It
would be useful in the same way that step is useful for the 'range'
function.

('range' and 'count' are very similar - 'count' could even be merged into
'range', for example by making 'range(None)' equivalent to 'count()')

[issue4874] decoding functions in _codecs module accept str arguments

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

The patch looks good. 
I think the missing b in test_errorcallback_longindex is an overlook
when the tests were updated for py3k. You are right to change the test.

[issue4874] decoding functions in _codecs module accept str arguments

[Antoine Pitrou]

Antoine Pitrou  added the comment:

"Fixing" multibytecodec.c produces a TypeError in the following test:

def test_errorcallback_longindex(self):
dec = codecs.getdecoder('euc-kr')
myreplace  = lambda exc: ('', sys.maxsize+1)
codecs.register_error('test.cjktest', myreplace)
self.assertRaises(IndexError, dec,
  'apple\x92ham\x93spam', 'test.cjktest')

TypeError: decode() argument 1 must be bytes or buffer, not str

Since the test is meant to test recovery from a misbehaving callback, I
guess the type of the input string is not really important and can be
changed to a bytes string instead. What do you think?

(in any case, here is a patch)

IMO, Modules/cjkcodecs/multibytecodec.c should be changed as well.

[issue5031] Thread.daemon docs

[steve21]

New submission from steve21 :

In the threading module the Thread.daemon documentation says:

"The thread’s daemon flag. This must be set before start() is called,
otherwise RuntimeError is raised.

The initial value is inherited from the creating thread.

The entire Python program exits when no alive non-daemon threads are
left."

I think the docs should state Thread.daemon's type (boolean, or integer,
or something else?) and its default value (when you have not set .daemon
in the creating thread.)

[issue5029] Odd slicing behaviour

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Why should it return an empty list?

>>> foo = [1,2,3]
>>> foo[1::-1]
[2, 1]
>>> foo[0::-1]
[1]

looks quite consistent to me.
