[issue12999] _XOPEN_SOURCE usage on Solaris

[Charles-François Natali]

New submission from Charles-François Natali :

While testing issue #12981, I stumbled on a problem on OpenIndiana buildbot:
"""
test test_multiprocessing crashed -- Traceback (most recent call last):
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/test/regrtest.py",
 line 1133, in runtest_inner
the_package = __import__(abstest, globals(), locals(), [])
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/test/test_multiprocessing.py",
 line 38, in 
from multiprocessing import util, reduction
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/importlib/_bootstrap.py",
 line 437, in load_module
return self._load_module(fullname)
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/importlib/_bootstrap.py",
 line 141, in decorated
return fxn(self, module, *args, **kwargs)
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/importlib/_bootstrap.py",
 line 342, in _load_module
exec(code_object, module.__dict__)
  File 
"/export/home/buildbot/64bits/custom.cea-indiana-amd64/build/Lib/multiprocessing/reduction.py",
 line 57, in 
raise ImportError('pickling of connections not supported')
ImportError: pickling of connections not supported
"""

Which means that socket.CMSG_LEN isn't defined.
Now, you might wonder how this can work in the C version of 
multiprocessing.(sendfd|recvfd), which needs CMSG_LEN().
Here's how:
"""
#ifdef __sun
 /* The control message API is only available on Solaris  
if XPG 4.2 or later is requested. */  
 #define _XOPEN_SOURCE 500 
 #endif
"""

And indeed:
http://fxr.watson.org/fxr/source/common/sys/socket.h?v=OPENSOLARIS#L478
"""
#if defined(_XPG4_2)
/*
 * The cmsg headers (and macros dealing with them) were made available as
 * part of UNIX95 and hence need to be protected with a _XPG4_2 define.
 */
"""

The problem is that socketmodule uses pyconfig.h defines, and _XOPEN_SOURCE 
isn't defined on Solaris:
http://hg.python.org/cpython/rev/7c947768b435

(it was added explicitely to Modules/_multiprocessing/multiprocessing.h for 
sendmsg by http://hg.python.org/cpython/rev/419901e65dd2).
So, _XOPEN_SOURCE is needed on Solaris to build socket_sendmsg and friends.
I'm not sure about the best way to proceed, since Martin certainly had good 
reasons to remove _XOPEN_SOURCE definition entirely on Solaris.
Should we define it only at the top of socketmodule?

[issue12981] rewrite multiprocessing (senfd|recvfd) in Python

[Charles-François Natali]

Charles-François Natali  added the comment:

> Did you try it on Linux, FreeBSD and/or Windows?

It works fine on Linux, FreeBSD, OS X and Windows, but not on Solaris: see 
issue #12999.

[issue12976] add support for MirBSD platform

[Charles-François Natali]

Charles-François Natali  added the comment:

Hello Benny,

> As requested, here is the full patch for MirBSD support. The diff was taken 
> against version 2.7.2. It is really quite easy, you just need to handle 
> MirBSD like OpenBSD.
> With this patch, I can successfully compile and run Python on MirBSD. Even 
> though it is a rather exotic platform, I encourage you to take these changes, 
> as they are quite minimal.

Indeed, it's quite short and manageable, but see
http://bugs.python.org/issue11937, especially Martin's and Terry's
comments:
"""
Guido established a policy a few years ago that we should rather not
incorporate support for every minority platform for which people
contribute patches. While I'd personally agree that an Interix port
would certainly be "fun", pragmatically, I'm -1 on having the code in
the code basis, and propose to close this issue as "won't fix".

We would certainly be happy to link to gentoo prefix from the "other
ports" page on python.org.
"""

and

"""
Markus, I agree with Martin that this patch would go against current
policy and should be closed. Rather than close it myself, I will try
to persuade you to do so.
[...]
"""

This patch is much simpler and cleaner though (OTOH, it's so simple it
shouldn't be too much work for MirBSD folks to keep this patch in
sync).

[issue12998] Memory leak with CTypes Structure

[Sebastian Wiesner]

Sebastian Wiesner  added the comment:

Why should it?  After all, you're sort of abusing ctypes by repeatedly creating 
Struture types over and over again.  C structures that you might want to wrap 
with these types are fixed and known at the time of programming, so there is 
never a need to create the same Structure type twice.  Thus the set of 
Structure subclasses created during the live-time of a program is both, fixed 
and small, so there is no need to limit the cache size.

[issue12998] Memory leak with CTypes Structure

[Stefan Krah]

Stefan Krah  added the comment:

I can reproduce the leak with Python 2.5.4, but not with Python 2.6.5
or Python 3.2.

Python 2.5.4 is an ancient version. Please upgrade to Python 2.7
or Python 3.2. If the leak still exists, just respond to this issue
and it will be opened again automatically.

[issue12981] rewrite multiprocessing (senfd|recvfd) in Python

[Charles-François Natali]

Charles-François Natali  added the comment:

Here's a patch taking into account the fact that
multiprocessing.reduction might not be available and importing it can
raise an ImportError (which is already the case with the C
implementation, but multiprocessing.reduction tests have been added
recently to test_multiprocessing), e.g. if the OS doesn't support FD
passing.
With this patch, the pure Python version can be applied, and passes on
Linux, FreeBSD, OS X, Windows and OpenSolaris (except that it's not
available on OpenSolaris until issue #12999 gets fixed).
I also slightly modified the struct format used in the pure Python
version to make sure the length is sent as a a native int ("@i")
instead of a standardized int ("=i"), which might break if sizeof(int)
!= 4 (not sure there are many ILP64 architectures out there, but you
never know...).

That won't work in IDLE because IDLE replaces the standard sys.stdout file

If that is the only problem, perhaps this issue should be reassigned to IDLE to

This fails because MSG_TRUNC isn't always set in msg_flags when receiving a

It's a known kernel bug

FreeBSD 8 (and the test indeed passes on the FreeBSD 8 buildbot).

The patch attached skips the test on FreeBSD < 8 (and introduces

[Éric Araujo]

Éric Araujo  added the comment:

> I'm not suggesting that python does not test the applications. just reporting
> what I experience.
I was joking :)  What I meant was: I can’t agree with the statement “it could 
be raised on any other usage as sys.stdout does not have an 'error' attribute” 
because we have tests and users that use distutils without seeing this error.

> What I did, I opened the setup file (in IDLE) from the distribute 0.6.21 and 
> run this.
setup.py is meant to be run from the command line only.  If you try to run it 
from IDLE, the behavior is undefined, so I’m inclined to close this bug as 
invalid.

(A note about this bug tracker: please do not send HTML email, it gets 
transformed into an unhelpful attachment, and also don’t include whole messages 
after your reply when you send email.  Thanks in advance!)

[issue1222585] C++ compilation support for distutils

[Éric Araujo]

Éric Araujo  added the comment:

Well, there’s no rush, Python 3.3b1 is not next week.

I’m willing to apply the patch to packaging and distutils2 (in a week or two 
when I’ve finished a massive cleanup and caught up with packaging), but I’d 
like tests for detect_language, and if possible tests for compiling C++ 
extensions/libs too.

It’s okay.  A recipe on ActiveState and a “shlexu” module on PyPI would also be 
good things to have.

shlex supports Unicode in 3.x.  If there is a bug, can you please open another 
bug report?  This one is already too long, and I’d prefer to keep it focused on 
the need for a documentation patch.

[issue12955] urllib.request example should use "with ... as:"

[Éric Araujo]

Éric Araujo  added the comment:

[Terry]
> But when I add 'http:www.python.org' as an argument, I get
> urllib.error.URLError: 

Your URI lacks a host (netloc, in RFC parlance) component:
>>> urllib.parse.urlparse('http:python.org')
ParseResult(scheme='http', netloc='', path='python.org', params='', query='', 
fragment='')

[issue12956] builds fail when installing to --prefix with space in path name

[Éric Araujo]

Éric Araujo  added the comment:

My sentiment too.  Supporting non-ASCII characters seems clearly important to 
me, as it’s a reasonable and common thing to run or install Python from a patch 
that may contain non-ASCII characters (a first name, “downloads” in French, 
etc.); supporting spaces is less important.

[R. David Murray]

R. David Murray  added the comment:

Ezio, I don't see any indication in this ticket that this bug was actually 
*fixed* in 3.x.  Unicode doesn't cause immediate errors in 3.x, but it isn't 
recognized as wordchars, etc.  Am I missing something?

[issue11935] MMDF/MBOX mailbox need utime

[Steffen Daode Nurpmeso]

Steffen Daode Nurpmeso  added the comment:

Let me close this!
I've just recently removed the real patch from my postman's "next"
branch, because even that real implementation doesn't work reliable.
I.e., please forget msg135791.  It was true, but on the long run
mutt(1) sometimes sees all, sometimes only some (really nuts), but
most of the time it simply does not see just any box with new mail.
That is, that "plugged-in filesystem" is simply handled as a pendant.

Remarks: because that stdlib MBOX whispered
  "Where Are Tho{u}, Brother"
to me all the {time}, i've done my own, also just recently:

== postman:
  - test: 321 messages (5083760 bytes) [action=hunky-dory]
  = Dispatched 321 tickets to 1 box.
  [69853 refs] real 0m35.538s user 0m6.760s sys 0m0.904s
..
  = Dispatched 1963 tickets to 1 box.
  [93552 refs] real 0m38.860s user 0m8.697s sys 0m0.985s
== stdlib:
  [83010 refs] real 1m3.862s user 0m10.151s sys 0m7.500s
  [93217 refs] real 7m24.958s user 2m0.174s sys 1m35.163s

Was worth it.
Have a good time!

[issue12737] str.title() is overzealous by upcasing combining marks inappropriately

[Ezio Melotti]

Ezio Melotti  added the comment:

I think string methods (and other parts of the stdlib) assume NFC and leave 
normalization to NFC up to the user.  Before fixing str.title() we should take 
a more general decision about handling strings that use other normalization 
forms.

[issue12977] socket.socket.setblocking does not raise exception if no data available

[Georg Brandl]

Georg Brandl  added the comment:

I think you're mistaking a closed connection with "no data available".

Small demo that this works as intended:

>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.connect(('localhost', 1234))
>>> s.recv(10)
^CTraceback (most recent call last):
  File "", line 1, in 
KeyboardInterrupt
>>> s.setblocking(False)
>>> s.recv(10)
Traceback (most recent call last):
  File "", line 1, in 
socket.error: [Errno 11] Resource temporarily unavailable

The corresponding server:

>>> x = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> x.bind(('', 1234))
>>> x.listen(1)
>>> x.accept()
(, ('127.0.0.1', 39146))

[issue12450] Use the Grisu algorithms to convert floats to strings

[Florian Loitsch]

Florian Loitsch  added the comment:

FYI: the double-conversion library at 
http://code.google.com/p/double-conversion already contains code for the 
fallback case. It would not be necessary to keep Python's existing code just 
for the 0.5%.
The library is now used by Firefox, Chrome, and Webkit, and should be well 
tested.
It's biggest deficiency (compared to Gay's dtoa.c) is its specialization to 
IEEE doubles. Floats or long doubles are not supported. If Python needs to 
support these types I recommend not to switch.

[issue12993] prepared statements in sqlite3 module

[poq]

poq  added the comment:

The sqlite3 module already uses prepared statements. Quoting from the 
documentation:

"The sqlite3 module internally uses a statement cache to avoid SQL parsing 
overhead. If you want to explicitly set the number of statements that are 
cached for the connection, you can set the cached_statements parameter. The 
currently implemented default is to cache 100 statements."

[issue12961] itertools: unlabelled balls in boxes

[Phillip Feldman]

Phillip Feldman  added the comment:

"The itertools module should only have a few of the most generally useful, 
especially in combination with other tools."

Balls-in-boxes _is_ one of the most basic of the canonical combinatorial 
problems.  You can verify this by opening any text on combinatorics or 
combinatorial probability.

"An extensive combinatorics package would be a different project. (And I have 
done a bit of work in this direction.)"

It sounds as though your project is in its infancy, but I'd like to see what 
you've got if you are willing to share.

Retested with Python 3.1.1 and this issue doesn't manifest. This can be 
resolved - sorry about the noise. :)

[issue13003] Bug in equivalent code for itertools.izip_longest

[Eli Bendersky]

New submission from Eli Bendersky :

Regarding the sample code in: 
http://docs.python.org/library/itertools#itertools.izip_longest

If an IndexError is raised inside an iterator in the "equivalent" code
from the docs, the generator stops and the error is swallowed.

If an IndexError is raised inside an iterator in the
"izip_longest_next" code in CPython's "Modules/itertoolsmodule.c", the
generator stops and the error propagates.

[issue13003] Bug in equivalent code for itertools.izip_longest

[Georg Brandl]

Georg Brandl  added the comment:

I had forwarded this to Raymond, and he replied:

The itertools module code is correct.
The "equivalent" is only approximately correct 
I don't consider it to be a bug -- it is an implementation detail in an 
illustration.

[issue13003] Bug in equivalent code for itertools.izip_longest

[Eli Bendersky]

Eli Bendersky  added the comment:

What about at least documenting it? Since a real user ran into this and 
reported it as a problem, I think it would make sense to make the discrepancy 
explicit.

Alternatively a generalized note can be added to the documentation of itertools 
stating that the "equivalent" code samples are only approximate and differ in 
small details from the real implementations.
