<p>Hi Ned,</p>
<p>I hope so!</p>
<p>The core of my mp code is:</p>
<p>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
</p>
<pre style="background-color:#ffffff;color:#000000;font-family:'DejaVu Sans Mono';font-size:9.0pt;">pool = Pool(<span style="color:#660099;">processes</span>=processes, <span style="color:#660099;">initializer</span>=init)
result = pool.imap_unordered(func, iterable)
started = datetime.now()
<span style="color:#000080;font-weight:bold;">try</span>:
<span style="color:#000080;font-weight:bold;">if </span>progress:
i = show_progress(started, result)
<span style="color:#000080;font-weight:bold;">else</span>:
<span style="color:#000080;font-weight:bold;">for </span>i, _ <span style="color:#000080;font-weight:bold;">in </span><span style="color:#000080;">enumerate</span>(result): <span style="color:#000080;font-weight:bold;">pass
</span><span style="color:#000080;font-weight:bold;">finally</span>:
pool.terminate()
pool.join()
</pre>
Does that look write/wrong?<br>

Do your workers exit cleanly?

<pre wrap="">Hi All,
I run my tests like this:
coverage run --concurrency=multiprocessing --source myproject,tests -m
nose && coverage report --skip-covered --show-missing
Some of the code is only reached by being called by some
multiprocessing.Pool workers, the pool being instantiated and fed by
one of the functions under test.
After running the above, I see:
$ ls -lah .coverage*
-rw-r--r--+ 1 chris staff 25K 6 Sep 19:31 .coverage
-rw-r--r--+ 1 chris staff 0B 6 Sep 19:30
.coverage.tweedledee.26019.082222
-rw-r--r--+ 1 chris staff 0B 6 Sep 19:30
.coverage.tweedledee.26020.787224
-rw-r--r--+ 1 chris staff 0B 6 Sep 19:30
.coverage.tweedledee.26021.467684
-rw-r--r--+ 1 chris staff 0B 6 Sep 19:30
.coverage.tweedledee.26022.663538
So, it looks like coverage is trying to record information in the
worker processes by failing. What might be the issue and how can I fix
it?
cheers,
Chris
