Hi,
I hit an issue with the following python code:
try:
get_orient = subprocess.Pope n (['jpegexiforient ', '-n', pathfull],
stdin = subprocess.PIPE ,
stdout = subprocess.PIPE )
orient = get_orient.comm unicate ()[0]
except:
orient = None
The intent of this was to read the exif orientation of a picture, or just
use None if jpegexiforient can not run.
The application worked fine on my devel machine but I noticed that on a
different host, it crashed due to running out of file descriptors.
After investigation I found out that the above code was responsible,
leaking two file descriptors per invocation if jpegexiforient is not
installed on the host.
I don't see any way to fix it in my code either, since get_orient is not
defined in the exception path, there is no way I can close its file
descriptors myself. I believe this is a bug in the subprocess module,
it should make sure to clean up after itself when getting out on the
exception path.
This looks like a duplicate of http://bugs.python.org/issue3210.
Can you confirm if this seems likely (and, if so, perhaps add
a note to the bug indicating that the problem is on Linux as well)?

Hello
My problem is that I want a Python 2.4 module on
a server that is running Python 2.3. I definitely
want to use the 2.4 module, and I don't want to
require the server to move to Python 2.4.
More exactly, I am using subprocess, which is
new in Python 2.4. What I am writing is something

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
