[issue3080] Full unicode import system

2011-03-10 Thread Amaury Forgeot d'Arc 

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:

Nice work! Is there a specific place for comments? Here are some of them 
already:

- Modules/zipimport.c::make_filename: remove the limit buffer, the code could
  look like:

  pathsize = PyUnicode_GET_SIZE(prefix) + PyUnicode_GET_SIZE(name);
  result = PyUnicode_FromUnicode(NULL, pathsize);
  path = PyUnicode_AS_UNICODE(ret);
  ...
  return result;

- Python/importdl.c::_PyImport_LoadDynamicModule: shortnameobj is not necessary:

  lastdot = Py_UNICODE_strrchr(nameuni, '.');
  if (lastdot == NULL)
  shortname = namenuni;
  else:
  shortname = lastdot + 1;

- _PyImport_GetDynLoadFunc still takes char* arguments. Can this fail on win32
  for example, in case the pathname cannot be encoded to mbcs?

[issue11459] Python select.select does not correctly report read readyness

2011-03-10 Thread Charles-Francois Natali 

Charles-Francois Natali neolo...@free.fr added the comment:

Could you try with the attached patch ?
The problem is that subprocess silently replaces bufsize=0, so child.stdout is 
actually buffered, and when you read just one byte, everything that's available 
for reading is read into the python's object buffer. Then, select/poll doesn't 
see the pipe as ready for reading since everything as already been read.
Mixing buffered I/O and select leads to trouble, you're right to pass 
bufsize=0, but I don't know why subprocess goes out of its way and buffers it 
anyway:
if bufsize == 0:
bufsize = 1  # Nearly unbuffered (XXX for now)

[issue11369] Add caching for the isEnabledFor() computation

2011-03-10 Thread Vinay Sajip 

Vinay Sajip vinay_sa...@yahoo.co.uk added the comment:

Bill,

I was looking at this patch again, and I'm not sure about thread safety. The 
correctness of the caching depends on manager.status, which is state which is 
potentially shared across threads. There are no interlocks around it, so with 
the patch as it stands, ISTM it's possible in a multi-threaded application to 
get stale information. Has your patch been used in multi-threaded applications?

[issue11461] Reading UTF-16 with codecs.readline() breaks on surrogate pairs

2011-03-10 Thread Yuriy Pilgun 

New submission from Yuriy Pilgun p...@ukrpost.net:

Reading UTF-16 text file with module 'codecs' fails, if surrogate pair is 
located at 72-character boundary.

Attached python script fails with message:
UnicodeDecodeError: 'utf16' codec can't decode bytes in position 70-71: 
unexpected end of data

The reason is splitting of input data for readline() into chunks, namely
  readsize = size or 72

So, nobody.  I still can't find a way to reproduce the errors, so.
I also get occasional errors when building _multiprocessor, which
disappear when (removing _multiprocessor_failed.so and) simply
running make all once again.
I thought about providing the patch anyway, but it is maybe better
to simply close this issue (in the meanwhile).

[issue11072] Add MLSD command support to ftplib

2011-03-10 Thread Eric Smith 

Eric Smith e...@trueblade.com added the comment:

I'll give this a proper review in the next day or so (busy at PyCon).

Despite the fact that I typically hate changing values returned by the server, 
I agree on case-folding the fact names to lowercase upon reading them. The RFC 
clearly states they're case insensitive: Fact names are case-insensitive.  
Size, size, SIZE, and SiZe are the same fact. You should have the facts in 
MLSD_DATA be mixed case, to ensure they're being lowercased correctly.

I agree that there's nothing that can be done in the case where no facts are 
specified: the spec clearly says just use the values we've previously set. 
Caller beware.

[issue11454] urllib.request import time

2011-03-10 Thread Ross Lagerwall 

Ross Lagerwall rosslagerw...@gmail.com added the comment:

OK, running this:
import base64
import bisect
import hashlib
import io
import os
import posixpath
import random
import re
import socket
import sys
import time
import collections

import io
import os
import socket
import collections
import warnings

import warnings
from io import StringIO, TextIOWrapper

import re
import uu
import base64
import binascii
import warnings
from io import BytesIO, StringIO

which is most of the imports that are generated when importing urllib.request 
takes about 0.62s.

Running this:
import email.message
import email.parser
import email
from email.feedparser import FeedParser
from email.message import Message
from email import utils
from email import errors
from email import header
from email import charset as _charset

which is the rest of the imports generated takes 0.105s.

It seems like importing the email module adds considerable time, affecting a 
bunch of other modules like urllib.request and http.client.

When looking at the code, it seems like a fair number of regular expressions 
are compiled when the email module is imported, causing the long import time. I 
wonder if this could be improved somehow?

 doesn't need to be specified for every module that directly or
 indirectly uses SSL. Instead, there should be support for a
 thread-local setting of the allowable CAs, and then no API changes are

While thread-local variables are fine in applications, I think they
should be avoided in libraries (especially the stdlib). There are too
many pitfalls (for example: the user decides to offload a network task
to a separate thread and different SSL parameters get silently used).

The API changes are quite simple, both in concept and in implementation.
I think explicit is really better than implicit when it comes to
security-critical parameters.

[issue11441] compile() raises SystemError if called from except clause

2011-03-10 Thread Daniel Urban 

Daniel Urban urban.dani...@gmail.com added the comment:

So, I see four possible solutions:

1. If we get a tuple, create the new tuple, normalize the exception, and store 
it.  If we get a SyntaxError instance, use its args, create the new tuple, 
normalize, and store.  (In this case a SyntaxError instance will be created 
twice.)

2. If we get a tuple, create the new tuple and store it without normalization.  
If we get a SyntaxError instance use its args to create the new tuple and store 
it without normalization.  (I think, that later it's still possible that a new 
SynaxError will be created, but we don't create it here.)

3. If we get a tuple, create the new tuple, and store it without normalization. 
 If we get a SyntaxError, take its args, create the new tuple, and call 
SyntaxError.__init__ with it. I think this will set all fields properly.

4. Like 3., but if we got a tuple, store the new tuple with normalization.

My patch currently does 1. 
My patch, without the PyErr_NormalizeException() call would be 2.
I think maybe 3. would be the best solution, or 4., if normalization is desired 
in all cases.

I can write a new patch, if the experts tell me what is the best solution from 
the four (or some other I didn't think of).

[issue10795] standard library do not use ssl as recommended

2011-03-10 Thread Mads Kiilerich 

Mads Kiilerich m...@kiilerich.com added the comment:

The response I got to this issue hinted that it was a lame issue I filed. I 
haven't had time/focus to investigate further and give constructive feedback.

I think it is kind of OK to require explicit specification of the ca_certs as 
long as it is made clear in all the relevant places that it _has_ to be done. I 
think it would be a good idea to deprecate the default value for ca_certs and 
issue a warning if ca_certs hasn't been specified (as None or a path).

I have heard that some Python variants come with the system ca_certs built in 
and hard-coded somehow. That is in a way very nice and convenient and a good 
solution (as long the user wants to use the same ca_certs for all purposes), 
but it would have to be available and reliable on all platforms to be really 
useful.

I'd choose solution 3, but instead of calling SyntaxError.__init__, call 
PyErr_NormalizeException().

[issue11441] compile() raises SystemError if called from except clause

2011-03-10 Thread Daniel Urban 

Daniel Urban urban.dani...@gmail.com added the comment:

Err... sorry, I don't understand again:

If we get a tuple, create a new, store it without normalization. That's okay, I 
understand.

If we get a SyntaxError instance, then take its args field, create the new 
tuple. Then call PyErr_NormalizeException(), with:
a) the new tuple? But this will create a new SyntaxError instance...
b) the old SyntaxError instance? But this won't correct the wrong fields of the 
instance. (I think SyntaxError.__init__ would correct them without creating a 
new instance.)
c) or replace the args of the SyntaxError instance with the new tuple, then 
call PyErr_NormalizeException() on the instance? But I think that still won't 
correct the other fields of the instance...

Sorry for all these questions... I'd just like to help.

[issue10795] standard library do not use ssl as recommended

2011-03-10 Thread Antoine Pitrou 

Antoine Pitrou pit...@free.fr added the comment:

 I think it is kind of OK to require explicit specification of the
 ca_certs as long as it is made clear in all the relevant places that
 it _has_ to be done. I think it would be a good idea to deprecate the
 default value for ca_certs and issue a warning if ca_certs hasn't been
 specified (as None or a path).

The recommended way from Python 3.2 upwards is to define a SSLContext
and use it when doing SSL operations. Many APIs have been updated to
accept a context, a few are remaining as I've said in my first comment.

 I have heard that some Python variants come with the system ca_certs
 built in and hard-coded somehow.

This is really some OpenSSL variants rather than some Python
variants. We can't control how the system (or user-supplied) OpenSSL is
built.
This feature is exposed in SSLContext.set_default_verify_paths() (see
http://docs.python.org/dev/library/ssl.html#ssl.SSLContext.set_default_verify_paths),
with the caveat that you don't know whether it succeeded at all.

 That is in a way very nice and convenient and a good solution (as long
 the user wants to use the same ca_certs for all purposes), but it
 would have to be available and reliable on all platforms to be really
 useful.

Well, for one, it probably won't be effective on Windows builds, since
it's really not Python's job to define a set of reliable CA certificates
(unless Martin wants to take that responsibility, that is), and Windows
doesn't have a set of system certificates in the PEM format AFAIK.

[issue4966] Improving Lib Doc Sequence Types Section

2011-03-10 Thread Ezio Melotti 

Ezio Melotti ezio.melo...@gmail.com added the comment:

This is maybe out of the scope of this issue, but I would like to see all the 
basic data types on single page on their own.  The current page[0] has some 
section about data types mixed with sections about operations, comparisons, and 
other things, followed by less-used types.  The page also contains lot of 
informations and it's not easy to browse (42 screens on a 24 monitor).

Ideally the structure should be something like:

1. True, False, None
2. int, float(, long, complex)
3. str, unicode, list, tuple(, bytearray, buffer, xrange)
4. dict
5. set(, frozenset)

(where the types in () are considered less important -- so maybe described in 
detail later or in another page).  The page can list common operations for each 
group and their methods, but leaving things like the string formatting 
operations to another page/section.

[issue4966] Improving Lib Doc Sequence Types Section

2011-03-10 Thread Ezio Melotti 

Ezio Melotti ezio.melo...@gmail.com added the comment:

The advantage of having one big page is that you can ctrl+f easily without 
having to go back and forth from different pages
On the other hand, the page is not easy to browse (especially on small screens, 
mobile devices, old/slow pcs).

In this case I don't think that splitting the page is a problem, because the 
page contains information about different and fairly unrelated thing.

With pages like unittest or logging is not so easy to split because while 
working with them you might need to use several different 
functions/methods/classes and having their docs on two or more page will be 
annoying.  (FWIW I've been working a lot on the unittest doc to make it more 
compact and easier to browse, but there's still work to do.  We have also 
been considering to make a page for unittest users that explains how to write 
tests and use the assert methods and another for unittest developers that 
explains how to write test runners, suites and more advanced stuff.)

BTW .rst is really easy, and if you are not sure about something just try to 
build the doc with make html and see if it complains and if the resulting 
page looks OK.  Also see http://docs.python.org/documenting/index.html.

[issue11462] Peephole creates duplicate and unused constants

2011-03-10 Thread Eugene Toder 

New submission from Eugene Toder elto...@gmail.com:

Peephole optimizer performs constant folding, however
1) When it replaces operation with LOAD_CONST it always adds a new constant to 
co_consts, even if constant with the same value is already there. It also can 
add the same constant multiple times.
2) It does not remove constants that are no longer used after the operation was 
folded.
The result is that code object after folding has more constants that it needs 
and so uses more memory.

Attached are patches to address this. Patch for 1) comes in 2 versions. PlanA 
is simple (it only needs changes in peephole.c), but does linear searches 
through co_consts and duplicates some logic from compiler.c. PlanB needs 
changes in both peephole.c and compiler.c, but is free from such problems. I 
favour PlanB.

Patch for 2) can be applied on top of either A or B.

[issue11462] Peephole creates duplicate and unused constants

2011-03-10 Thread Raymond Hettinger 

Raymond Hettinger rhettin...@users.sourceforge.net added the comment:

Sorry Eugene, but I'm not willing to add that much complexity to save a few 
bytes.  This was a known issue and long ago we choose to leave it as-is.  In 
the future when constant folding is done at the AST level, we'll get more 
extensive optimizations and they won't produce duplicate or unused constants as 
a by-product.

[issue11462] Peephole creates duplicate and unused constants

2011-03-10 Thread Eugene Toder 

Eugene Toder elto...@gmail.com added the comment:

I think the changes are fairly trivial. dedup_const_planb.patch is about 10 
lines of new code with all the rest being trivial plubming. unused_consts.patch 
may look big, but only because I factored out fix ups into a separate function; 
there are only about 25 lines of new code.

[issue11406] There is no os.listdir() equivalent returning generator instead of list

Why kernel.org is slow

To proove that readdir is bad thing on large number of items in a directory.

Well, EXT4 has fixed some issues 
(http://ext2.sourceforge.net/2005-ols/paper-html/node3.html) But what about 
locking in linux kernel (vfs and ext4) code?

Also, some conservative linuxes still use ext3.

New submission from yufun heyt1...@gmail.com:

appsLib =cdll.LoadLibrary(util.find_library('ApplicationServices'))

[issue11426] CSV examples can't close their files

2011-03-10 Thread Eli Bendersky 

Eli Bendersky eli...@gmail.com added the comment:

The attached patch tries to be true to the convention in other documentation 
pages, by using with in complete code samples (examples), but not using it in 
prompt () samples, where usage of with unnecessarily complicates 
interaction.

[issue5228] multiprocessing not compatible with functools.partial

2011-03-10 Thread uptimebox 

uptimebox m...@uptimebox.ru added the comment:

Unfortunately, upgrading to 2.7 is not an option for me, since my application 
works on Debian stable which only includes 2.6. For now I'm settled with the 
following workaround: http://paste.pocoo.org/show/351774/

[issue8995] Performance issue with multiprocessing queue (3.1 VS 2.6)

2011-03-10 Thread Charles-Francois Natali 

Charles-Francois Natali neolo...@free.fr added the comment:

Could you try with Python 3.2 ?
In 3.1, the only available pickle implementation was in pure python: with 
cPickle (2.7) or _pickle (3.2), it should be much faster.
