2017-07-06move flatten dict key to common utilsrexlee87761-5/+8
So it can easily be used by other testcase to unify result JIRA: YARDSTICK-702 Change-Id: Id4fde38a9a0c2a87a6c870bdb7b0c8f3a3b371ac Signed-off-by: rexlee8776 <limingjiang@huawei.com>
2017-04-11standardize ssh authRoss Brattain1-8/+2
we need to be following defautl paramiko rules, first use pkey, then key_filenames (autodetecting ~/.ssh/ keys), then password We have too much boilerplate redudant code everywhere, we need to standardize on a factory function that takes a node dict. Using Python3 ChainMap we can layer overrides and defaults. VNF descriptors have to default key_filename, password to Python None. The only way to do this is to omit key values if the variable is not defined, this way the dict will not have the value and it will default to Python None Add python2 chainmap backport Updated unittest mocking to use ssh.SSH.from_node Change-Id: I80b0cb606e593b33e317c9e5e8ed0b74da591514 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
2017-01-12Add support for Python 3Ross Brattain1-5/+11
Porting to Python3 using Openstack guidelines: https://wiki.openstack.org/wiki/Python3 This passes unittests on Python 3.5 and passes opnfv_smoke suite Updates: use six for urlparse and urlopen fix exception.message attribute removal run unittests on python3 use unitest.mock on python 3 fix open mock for vsperf fix float division by using delta/eplison comparison use unicode in StringIO use plugin/sample_config.yaml relative path from test case fixed apexlake unittests upgraded to mock 2.0.0 to match python3 unittest.mock features fixed flake8 issues implement safe JSON decode with oslo_serialization.jsonutils.dump_as_bytes() implement safe unicode encode/decode with oslo_utils.encodeutils heat: convert pub key file from bytes to unicode pkg_resources returns raw bytes, in python3 we have to decode this to utf-8 unicode so JSON can encode it for heat template JIRA: YARDSTICK-452 Change-Id: Ib80dd1d0c0eb0592acd832b82f6a7f8f7c20bfda Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
2016-12-05use context manager for stdin files and use _put_file_shellRoss Brattain1-6/+6
requires https://gerrit.opnfv.org/gerrit/#/c/25183/ use new ssh method _put_file_shell to upload files. We have to use _put_file_shell because we rely on ~/ path expansions. Eventually we should move to remote absolute paths so we can use sftp upload. For ssh.execute() replace open() with context manager context managers were invented partly to control freeing resources. Opening files without closing them will leak file descriptors. The old standard method for closing files: f = open('data.txt') try: data = f.read() finally: f.close() was replaced with a context manager with open('data.txt') as f: data = f.read() Reference: Raymond Hettinger's Pycon 2013 presentation: https://speakerdeck.com/pyconslides/transforming-code-into-beautiful-idiomatic-python-by-raymond-hettinger-1 Video: https://youtu.be/OSGv2VnC0go?t=2522 Always use context managers for files Update: rebased now that _put_file_shell was merged Change-Id: Iabfc0e43aa3b7766d7c658115e13d21c31efb2a9 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
2016-11-10add option to connect to non-standard ssh portRoss Brattain1-1/+3
not all enviroments have port 22 enabled for SSH. In particular for network isolation NAT and port forwarding may be used. example pod.yaml: nodes: - ip: 10.2.45.145 name: node1 password: '' role: Controller ssh_port: 5000 user: root - ip: 10.2.45.145 name: node2 password: '' role: Controller ssh_port: 5001 user: root - ip: 10.2.45.145 name: node3 password: '' role: Controller ssh_port: 5002 user: root JIRA: YARDSTICK-407 Change-Id: I8f9d6e388f31d291dd15cb900d7f71f347e41ef6 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>

2015-12-21Fix lmbench memory read latency stop sizeKristian Hunt1-4/+4
Stop size parameter's type should be float to allow for performing measurements on only L1 and L2 cache if needed. JIRA: - Change-Id: Ibc4d052c343e9dcccf6101c6c949172bb5a0f9e1 Signed-off-by: Kristian Hunt <kristian.hunt@gmail.com>
2015-10-28Extend lmbench scenario to measure memory bandwidthKristian Hunt1-21/+77
Lmbench scenario has now two scripts and will choose between them, based on whether the intention is to run memory latency or bandwidth tests. Added also unit test file for this scenario.

2015-10-27Heat context code refactor part 2QiLiang1-21/+25
Heat context code refactor to cater for the evolution of the Yardstick framework. Refactor runner_cfg host/target info handle, as specified at https://etherpad.opnfv.org/p/yardstick_framework step 4. Get general Context info (use Context.get). Before this refactor host and target vm must have the same user name and ssh key, that is not general enough for later extension. test_case.yaml do NOT need to change.

2015-09-16Remove setting logger level to debug in scenariosKristian Hunt1-2/+1
Logging level should be specified using a command line flag -v or -d when running yardstick, rather than hardcoded into source code. If the message is to be displayed whenever yardstick is executed regardless of the verbosity level, then the message should be logged to warning or error levels, instead of debug.
