Joshua McKenzie commented on CASSANDRA-9897:
--------------------------------------------
After dealing with escaping and the fact that c:\temp explodes on the archiver
(since \t is an escape character), I'm now wrestling with the fact that
subprocess.communicate() is blocking indefinitely during node.nodetool in ccm
*if called from dtests* on Windows. Running "ccm node1 nodetool flush" from a
command-prompt works fine, but blocks on .communicate during the chain of calls
to try and force a flush during snapshot tests:
{code}
if capture_output:
p = subprocess.Popen(args, env=env, shell=True, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
stdout, stderr = p.communicate()
{code}
[~philipthompson] / [~tjake]: Either of you have any ideas on this one? I'm
stumped. Logs from the node shows that it's flushing and returning as one would
expect but the dtest just hangs there and never gets past p.communicate()
> Windows dtest: snapshot_test.py failures
