2017-02-08vnf_generic: convert sshmanager to classRoss Brattain1-2/+2
@contextmanager have an issue with respect to exceptions that makes them not suitable for real usage. @contextmanager uses yield to create a generator and then uses generator.throw() to raise any exceptions. Exceptions thrown from generators loose their call stack due to the way generators work, so any exception inside a context manager is harder to debug. For this reason we don't use @contextmanager and instead always define a new class with __enter__ and __exit__. There is sample code that demonstrates the issue with @contextmanager and generator.throw() here https://gist.github.com/rbbratta/e28b6e64a4551522c3ac9815ca7f25f0 Change-Id: I5383c01f40a63e33680112f39b5bd9c858e328f1 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>

TrafficProfile is a generic class to get traffic profile for a given testcase and select the traffic generator for testcase. 3. QueueFileWrapper is a class to send/recive cmds to vnf 4. GenericVNF is a generic class to instantiate VNF 5. GenericTrafficGen is a generic class to run/listen/verify traffic.

The .format() won't work, since it can't slice the uuid We have to convert the uuid to string before we slice it. I thought .format() would implicitly call __str__() before applying width, but that is not the case. 'files/yardstick_key-{:.{width}}'.format(self.key_uuid, width=8)) We also need to define a constant short uuid lenght, we can't hardcode the length to 8 everywhere.

2017-01-10associate an uuid to yardstick_key and yardstick_key.pubJingLu51-1/+15
JIRA: YARDSTICK-527 This work is to support yardstick parallel tasks in the future. Currently, the RSA key we generated and used to access the VM is named 'yardstick_key'. If more than two tasks are running paralleled, the later 'yardstick_key' will cover the former. We want associate an uuid to identify differnets for each tasks. So the key files won't conflict. The first 8 digits will be used, as there is no need to used a full-length uuid. Change-Id: If8eaf47ae527cf9b3bd50f37ab3051fbdccf5f03 Signed-off-by: JingLu5 <lvjing5@huawei.com>
