Oops.  I did locate the directory on a backup.  As you supposed, I had
created queue.py initially to do the test.  I re-ran it as 'q.py' to see if
that helped, but did not delete the original.  So you were right -- name
conflict.

I no longer have the directory in which I did this trial.  However, trying
again in an empty directory, the sample works fine with 3.5.

[Touch-packages] [Bug 1628763] Re: Example of Queue from documentation fails

2017-10-10 Thread Serhiy Storchaka 
This looks like there is a queue.py file in the current directory which
hides the queue module from the stdlib. In Python 2.7 this module is
named Queue and doesn't conflict with a local file queue.py.

Can you confirm Kevin?

2016-09-29 Thread Kevin O'Gorman 
Noting still further: When I tried the same program with the default
Python (2.7), it worked just as the documentation promised, so the
problem is in the Python 3.5 build.

[Touch-packages] [Bug 1628763] Re: Example of Queue from documentation fails

2016-09-29 Thread Kevin O'Gorman 
Noting further: There's a Note at the bottom of the entry for Queue in 17.2.2.2,
https://docs.python.org/3.5/library/multiprocessing.html#pipes-and-queues
which says that ImportErrors can be caused by failure of the system to support 
semaphores, as outlined in Issue3770 (Closed years ago):
https://bugs.python.org/issue3770

Does Xubuntu not have basic IPCs such as semaphores?  Is it a problem in
how Python is built?
