I think that optparse is doing the right thing here. I think that your code
example should be changed to:
import optparse
parser = optparse.OptionParser()
parser.add_option(-o, --option, action = append)

The following snippet behaves differently in the C IO implementation than in
the Python IO implementation:

sys.stdout.write('unicode ')
sys.stdout.buffer.write(b'bytes ')
To test this, I have created two scripts
Andrew McNabb amcn...@mcnabbs.org added the comment:
This seems like a common need (particularly for stdout and stderr), and setting
`stdout._CHUNK_SIZE = 1` is relying on an implementation detail.
1) Can the documentation for TextIOWrapper be updated to clearly describe this
extra buffering
Andrew McNabb amcn...@mcnabbs.org added the comment:
I would imagine that this would come up in most programs that read data from a
pipe or from a socket (which are binary data) and then output to stdout or
stderr. I ran across the problem in my first non-trivial port to Python 3
Andrew McNabb amcn...@mcnabbs.org added the comment:
I'm seeing something very similar to this. In my case, I have a
single-threaded program, and select fails to be interrupted by SIGCHLD. I'm
still tracking down more details, so I'll report back if I find more
information.

The What's New documentation for Python 3.0 and 3.1 have sections called
Porting to Python 3.0. It would be great to add a link to the Python wiki
page about porting Python to Python 3:

Andrew McNabb amcn...@mcnabbs.org added the comment:
What advice in particular do you consider bad? I would be happy to submit some
changes to the wiki page for anything that's wrong.
I think it would be great to have a reviewed version in the documentation
directly, but I think the world
Andrew McNabb amcn...@mcnabbs.org added the comment:
By the way, I just noticed your notes on the wiki page and added a
response/question. It seems that the advice that you consider bad is the
official porting story (upgrade to 2.6 and use 2to3). I agree that it's easier
and better
Andrew McNabb amcn...@mcnabbs.org added the comment:
Thanks for your advice. I just signed up for the python-porting list, and I'll
start a discussion there.
I'm trying to improve the wiki page to address your concerns. There are
multiple valid approaches to take, and I'm trying to make

I ran into this problem, too. It took me a long time to track down the
segfaults. It's really bad to pass in None and have the system pick
some random address instead of 0.
I looked at the attached patch, and it seems to me the only

The stream encoder for the zlib_codec doesn't use the incremental encoder, so
it has limited usefulness in practice. This is easiest to show with an example.
Here is the behavior with the stream encoder:

Hmm. Maybe there's a difference between doing stat('/net/prodigy') vs.
stat('/net/prodigy/tmp'). Just a guess, but maybe the former can succeed before
the mount completes, but the latter has to wait for the mount to complete
Andrew McNabb amcn...@mcnabbs.org added the comment:
By the way, if my hunch about the difference in stat of '/net/prodigy' vs.
'/net/prodigy/tmp' is correct, then this would explain why makedirs on deeper
directories work. Specifically, one of the shallower stat calls would force the
mount

I see no evidence that this is a bug in Linux, and I think it's ridiculous to

Which one-line fix do you propose?
Doing a stat(/net/prodigy/tmp) before mkdir(/net/prodigy/tmp) is an
extremely simple workaround.
Of course, I would love to see clear documentation of how the kernel is defined
to behave
Andrew McNabb amcn...@mcnabbs.org added the comment:
Maybe I'm confused, but the presence of /net/prodigy is *not*
the issue here, and what gets mounted is *not* /net/prodigy,
but /net/prodigy/tmp (do mount to confirm or dispute).
No, /net/prodigy is the mountpoint in this case:

The --no-user-cfg option works for me in Python 2.7, but it does not seem to be

Am I doing something wrong, or was this feature only added to Python 2.7?
