[issue10015] Creating a multiprocess.pool.ThreadPool from a child thread blows up.

[Alister Cordiner]

Alister Cordiner  added the comment:

I think that workaround should be:

if not hasattr(threading.current_thread(), "_children"):
threading.current_thread()._children = weakref.WeakKeyDictionary()

[issue13237] subprocess docs should emphasise convenience functions

[Ezio Melotti]

Ezio Melotti  added the comment:

I think Éric is referring to the foo(bar, *, baz=None) syntax.  In 2.7 you can 
drop the '*' and still leave only the keyword arguments that you think are more 
useful.
I also see that you converted a few examples to use shell=True, but afaiu that 
should be avoided (even if the input is trusted, it can be a bad example and 
lead to escaping issues).
For the 'exit 1' example you could add a note saying that the example is run 
with shell=True because 'exit' requires a shell, or just keep the more verbose 
Python version.
My concern is that many people just go trough the examples and copy/paste what 
they see without reading the text around unless it's necessary to make the 
command work, so, if many examples use shell=True, they might end up picking 
one of those.

[issue13207] os.path.expanduser breaks when using unicode character in the username

[STINNER Victor]

STINNER Victor  added the comment:

Python 2 uses byte strings. If characters are not encodable to the ANSI code 
page, Windows replaces them by question marks. See the issue #13247 for another 
example (in Python 3 when using explicitly the bytes API). To be able to 
support characters not encodable to the ANSI code page, you have to use Unicode 
*everywhere*.

Because Python 2 doesn't have access to the Unicode environment and uses bytes 
in most cases, I don't think that we can fix this issue in Python 2.

I close this issue because it would require too much work to fix this issue in 
Python 2, whereas it already works in Python 3.  Move to Python 3 is the best 
solution of this issue.

[issue13271] When -h is used with argparse, default values that fail should not matter

[Joshua Chia]

New submission from Joshua Chia :

What steps will reproduce the problem?
1. Make a script containing this code:

 parser = argparse.ArgumentParser()
 parser.add_argument('-i', '--input-base-directory',
 type=argparse.FileType('r'),
 default='/home')
 parser.parse_args()

2. Run the script with '-h'.
3. See it complain that '/home' is a directory

Detailed explanation:
With '-h', we just need to print the help message. We shouldn't fail on a 
default value that's wrong or else the help message will not get printed and 
the user will have no idea what the problem is. This is a valid use case as I 
want to provide a default location, but I can't guarantee that the location 
works on the user's machine. I end up doing my own checking.

Nick Coghlan  added the comment:

That's deliberate, as I'm only showing a selected subset of the full
signature at that point and using the subprocess API's with positional
arguments would lead to almost incomprehensible code. I'm not in any great
hurry to forward port though, so I'm happy to wait until you get a chance to
review the changes.

[issue5661] asyncore should catch EPIPE while sending() and receiving()

[Xavier de Gaye]

Xavier de Gaye  added the comment:

> I am not marking 'test needed' since the problem is 'hardly reproducible'.

The attached script named 'asyncore_epipe.py' may be used to reproduce
systematically the EPIPE error on linux with Python 3.2:

* the Reader closes the socket after receiving the first data
* the Writer gets an exception when attempting to write the next
  message on the closed socket

When you run 'python asyncore_epipe.py' or 'python asyncore_epipe.py
1025' you get an EPIPE error (1025 is the size of exchanged messages,
so the last Writer message has been fully read by the Reader before
closing).

When you run 'python asyncore_epipe.py 128' you get an ECONNRESET (the
Reader reads only 128 bytes before closing the socket)

Note that ECONNRESET has been removed in this script, from the
frozenset of handled errors, to make this last point visible.

So it seems that, on linux, when writing to a closed socket, you get
an ECONNRESET when there is still data in the socket, and an EPIPE
otherwise. In the first case the tcp connection ends with a single
RESET, and in the second case it ends with the sequence FIN-ACK-RESET.

[issue13247] os.path.abspath returns unicode paths as question marks

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Yuval, you are assuming that *no one* who uses the os byte APIs on Windows is 
either checking for '?' in returned paths or catching later exceptions. With 
Google code search, I did find one instance where someone tests paths for '?' 
after encoding with the file system encoding. It was not an instance of os.xxx 
output, but it is the same idea.

In any case,
1. Our experience is that any change will affect someone. I was the victim of a 
'harmless' micro change introduced in 3.1.2 (an intentional violation of the 
bugfix-only rule in bugfix releases -- and the last that I know of ;-).
2. The change will introduce an incompatibility between 3.2- and 3.3+.

The justification that mitigates the above is that there is little reason to 
request os bytes returns. By the same reasoning, the change is hardly worth 
bothering with as there should be little to no benefit in real code. So I am 
+-0 on the change.

[issue13188] generator.throw() ignores __traceback__ of exception

[Petri Lehtinen]

Petri Lehtinen  added the comment:

It seems this cannot be achieved the same way in 2.7 as the traceback is not 
directly associated with the exception. However, if we're currently in an 
exception handler and sys.exc_info() corresponds to the exception passed to 
generator.throw(), we could use the current traceback. Would this approach be 
too complicated and not worth it?

[issue13236] unittest needs more flush calls

[Peter Eisentraut]

Peter Eisentraut  added the comment:

Attached is a test file.  The key here is that I'm running the unittest suite 
inside of a long-running server process, so there is no predictable point of 
exit and cleanup.  Therefore, the steps I show at the end of the file should be 
run in an interactive interpreter.  Here is what I see:

>>> import unittest 
>>> 
>>> import testcase 
>>> 
>>> unittest.main(module=testcase)
.F.
==
FAIL: test_three (testcase.test)
--
Traceback (most recent call last):
  File "testcase.py", line 35, in test_three
self.fail("intentional failure")
AssertionError: intentional failure

--
Ran 3 tests in 0.002s

FAILED (failures=1)

That's good.

But:

>>> import unittest 
>>> 
>>> import testcase 
>>> 
>>> unittest.main(module=testcase, testRunner=testcase.FunnyTestRunner, 
>>> exit=False) 
.
F
.


You see, the test report at the end is missing.

I'm happy to consider other ways of addressing this, if anyone has an idea.

[issue6397] Implementing Solaris "poll" in the "select" module

[Jesús Cea Avión]

Jesús Cea Avión  added the comment:

First version of the patch. Review 0ee4386d8f51.diff 
http://bugs.python.org/file23526/0ee4386d8f51.diff

Details:

1. Current code aliases "devpoll" in platforms with "/dev/poll" (Solaris and 
derivatives). Considering all the other points, I think that providing a 
separate "select.devpoll" object would be a better idea. Opinions?.

2. I am not providing the exception contract documented in "select.poll". For 
instance, "poll.unregister" of a "fd" not previously registered doesn't raise 
an exception. Idem "poll.modify", etc. I could do it, but is pointless extra 
code.

3. I have added a boolean "select.isdevpoll" to indicate if "selec.poll" uses 
"poll()" or "/dev/poll". Ugly.

4. I release the GIL when waiting for the fds, but not when 
registering/unregistering fds, etc. I guess that the syscall would be very 
fast, but I haven't actually measure it.

5. The internal REMOVE is because if you "register" several times the same fd, 
the events are ORed. To avoid that I do an internal REMOVE first. I should scan 
the pollfds internally and update the events inplace. Or provide a separate 
"devpoll" and document this fact...

6. If the number of active fds is bigger that SIZE_DEVPOLL, only SIZE_DEVPOLL 
fds are returned. If you "poll" several times, you get the SAME fds, if they 
are still active. So, others active fds can suffer of starvation. Solutions: 
selftunning (if the module provide 20 slots and the OS provide 20 active fds, 
call again with 40 free slots, etc) or provide a separate "devpoll" and 
document this fact, posibly providing a "maxsize" parameter. "select.epoll" 
uses FD_SETSIZE, directly.

With this, I am starting to think that providing a separate "select.devpoll" is 
actually a better idea.

Opinions?.

[issue13241] llvm-gcc-4.2 miscompiles Python (XCode 4.1 on Mac OS 10.7)

[Ned Deily]

Ned Deily  added the comment:

Haypo, the OP has a workaround. IMO, we should not be making any 
recommendations about which Apple compiler to use on OS X 10.7 until we have 
completed test cycles of each.  There are too many variables at the moment.  I 
am doing that and should have results in a few days.

[issue13268] assert

[Alexander Myodov]

New submission from Alexander Myodov :

The extended version of assert statement has a strange violation of documented 
behaviour.

According to the 
http://docs.python.org/reference/simple_stmts.html#the-assert-statement, 
"assert expression1, expression2" should be equivalent to "if __debug__: if not 
expression1: raise AssertionError(expression2)". Nevertheless, it is not so for 
the following scenario:

class A(object):
def __str__(self):
return "str"
def __unicode__(self):
return "unicode"
def __repr__(self):
return "repr"

expression1 = False
expression2 = (A(),)

That is, when expression2 is a single-item tuple, assert statement prints the 
str-evaluation of the item itself, rather than of the tuple.

This occurs in 2.x branch only, seems fixed in 3.x, and it would be great to 
have it backported for consistency.

[issue13241] llvm-gcc-4.2 miscompiles Python (XCode 4.1 on Mac OS 10.7)

[STINNER Victor]

STINNER Victor  added the comment:

I asked for more information about llvm-gcc on IRC (#llvm). Extracts:

 - "llvm-gcc is not maintained." ("Clang and DragonEgg are.) "Apple is the 
maintainer of Apple's version of llvm-gcc and clang."
 - "Apple ships a [llvm-gcc] branch at a random point in svn + some bug fixes, 
not a proper release."
 - "llvm-gcc is Apple's GCC (which was never sync'd with mainline past 4.2.1 
because the FSF changed the license) with LLVM on the back end."
 - llvm-gcc-4.5 in Ubuntu 10.10 is not llvm-gcc, it's dragonegg, a new project

If I understood correctly, llvm-gcc is only the default C compiler of Xcode 
4.1. I don't think that you should workaround llvm-gcc bugs. If you are using 
Xcode 4.1, you can compile Python with clang. clang is a different C compiler 
and it doesn't have the bug.

[Nick Coghlan]

Nick Coghlan  added the comment:

Absent any further feedback, I think I'm done with the changes to the 2.7 
subprocess docs. I'll let them sit for a few days, then do the forward port to 
3.2 and default.

There are a couple of additional changes I'll add to the 3.x versions:
- mention redirecting to DEVNULL as a way of suppressing output when using 
call() and check_call()
- mention the UTF-8 assumption involved in using the universal newlines mode 
for pipes in 3.x (i.e. the stuff I mistakenly checked in to 2.7 and then 
reverted)

[issue13247] os.path.abspath returns unicode paths as question marks

[STINNER Victor]

STINNER Victor  added the comment:

> Yuval Greenfield  added the comment:
> Another option btw is to use utf-16

UTF-8, UTF-16 or any encoding different than the ANSI code page are not an 
option. The Windows bytes API expect filenames encoded to the ANSI code page. 
os.listdir() would raise an error (unknown directory) or return an empty list 
instead of the content of the directory.

I scanned through the libs for Python 2.7, 3.2, and 3.3 and there is no

[issue13267] Add an option to disable importing orphaned bytecode files

[Nick Coghlan]

Nick Coghlan  added the comment:

This feature is unnecessary now that PEP 3147 has been adopted. The way it 
works in 3.2+ is that orphaned bytecode files inside __pycache__ are always 
ignored, while bytecode files that live directly in the source directories are 
always imported.

This handles both use cases nicely:
- the implicitly created cache files are ignored if their source file has been 
deleted
- bytecode only distribution is still supported by explicitly installing 
bytecode files instead of source files

I don't have use case. But does raising UnicodeEncodeError fix
problems?  It could break existing code, but I don't see much
difference over WindowsError caused by the broken file names.

Agreed. So I think adding Windows specific check to Byte API does not
improve situation, but increase complexity of std lib.

[issue13267] Add an option to disable importing orphaned bytecode files

[Petri Lehtinen]

New submission from Petri Lehtinen :

This has been discussed in python-ideas approx. two years ago:

http://mail.python.org/pipermail/python-ideas/2009-December/006635.html

It seems to me that having an opt-in command-line option, environment variable 
and sys variable to disable loading orphaned bytecode files upon import had 
most use cases and gained most support.

[issue13247] os.path.abspath returns unicode paths as question marks

Yuval Greenfield  added the comment:

Another option btw is to use utf-16, which will work but it's a bit ugly as 
well:

>>> os.listdir(os.path.abspath(u'.').encode('utf-16'))
[]
>>> os.path.abspath(u'.')
u'C:\\Users\\alon\\Desktop\\\u05e9\u05dc\u05d5\u05dd'
>>> os.path.abspath(u'.').encode('utf-16')
'\xff\xfeC\x00:\x00\\\x00U\x00s\x00e\x00r\x00s\x00\\\x00a\x00l\x00o\x00n\x00\\\x

>>> os.listdir(os.path.abspath(u'.').encode('utf-16'))
[]

Tested on python 2.7, but you know what I mean.
