Brad Schoening updated CASSANDRA-17397:
---------------------------------------
Description:
The cqlshlib unit tests have some regular failures and warnings.
# test_copyutil.py fails with too many open files when ulimit is 256
# nose creates deprecated warnings
# cassconnect.py:39: DeprecationWarning: Legacy execution parameters
# sslhandling.py:42: DeprecationWarning: The SafeConfigParser class has been
renamed to ConfigParser
The cqlshlib test test_copyutil.py fails on MacOS with
*E OSError: [Errno 24] Too many open files*
This happens because the test does not close the file descriptors after use.
The default ulimit on MacOS is small, 256:
% ulimit -n
256
The simple fix is to close the pipe after use. Increasing ulimit nofiles works
also, but shouldn't be necessary.
