Yardstick +is intended to run on a computer with access and credentials to a cloud. The +test case is described in a configuration file given as an argument. + +How it works: the benchmark task configuration file is parsed and converted into +an internal model. The context part of the model is converted into a Heat +template and deployed into a stack. Each scenario is run using a runner, either +serially or in parallel. Each runner runs in its own subprocess executing +commands in a VM using SSH. The output of each command is written as json +records to a file. + +Install +======= + +TBD + +Run +=== + +TBD + +Custom Image +============ + +pktgen test requires a ubuntu server cloud image +TBD + +Development Environment +======================= + +Example setup known to work for development and test: +- Development environment: Ubuntu14.04, eclipse, virtual environment +- Cloud: Mirantis OpenStack 6.0 deployed using Virtualbox + +Create a virtual environment: +$ sudo apt-get install python-virtualenv +$ virtualenv ~/yardstick_venv +$ source ~/yardstick_venv/bin/activate +$ python setup.py develop + diff --git a/ez_setup.py b/ez_setup.py new file mode 100644 index 000000000..a693849f9 --- /dev/null +++ b/ez_setup.py @@ -0,0 +1,332 @@ +#!/usr/bin/env python +"""Bootstrap setuptools installation + +To use setuptools in your package's setup.py, include this +file in the same directory and add this to the top of your setup.py:: + + from ez_setup import use_setuptools + use_setuptools() + +To require a specific version of setuptools, set a download +mirror, or use an alternate download directory, simply supply +the appropriate options to ``use_setuptools()``. + +This file can also be run as a script to install or upgrade setuptools. +""" +import os +import shutil +import sys +import tempfile +import zipfile +import optparse +import subprocess +import platform +import textwrap +import contextlib + +from distutils import log + +try: + from urllib.request import urlopen +except ImportError: + from urllib2 import urlopen + +try: + from site import USER_SITE +except ImportError: + USER_SITE = None + +DEFAULT_VERSION = "6.1" +DEFAULT_URL = "https://pypi.python.org/packages/source/s/setuptools/" + +def _python_cmd(*args): + """ + Return True if the command succeeded. + """ + args = (sys.executable,) + args + return subprocess.call(args) == 0 + + +def _install(archive_filename, install_args=()): + with archive_context(archive_filename): + # installing + log.warn('Installing Setuptools') + if not _python_cmd('setup.py', 'install', *install_args): + log.warn('Something went wrong during the installation.') + log.warn('See the error message above.') + # exitcode will be 2 + return 2 + + +def _build_egg(egg, archive_filename, to_dir): + with archive_context(archive_filename): + # building an egg + log.warn('Building a Setuptools egg in %s', to_dir) + _python_cmd('setup.py', '-q', 'bdist_egg', '--dist-dir', to_dir) + # returning the result + log.warn(egg) + if not os.path.exists(egg): + raise IOError('Could not build the egg.') + + +class ContextualZipFile(zipfile.ZipFile): + """ + Supplement ZipFile class to support context manager for Python 2.6 + """ + + def __enter__(self): + return self + + def __exit__(self, type, value, traceback): + self.close() + + def __new__(cls, *args, **kwargs): + """ + Construct a ZipFile or ContextualZipFile as appropriate + """ + if hasattr(zipfile.ZipFile, '__exit__'): + return zipfile.ZipFile(*args, **kwargs) + return super(ContextualZipFile, cls).__new__(cls) + + +@contextlib.contextmanager +def archive_context(filename): + # extracting the archive + tmpdir = tempfile.mkdtemp() + log.warn('Extracting in %s', tmpdir) + old_wd = os.getcwd() + try: + os.chdir(tmpdir) + with ContextualZipFile(filename) as archive: + archive.extractall() + + # going in the directory + subdir = os.path.join(tmpdir, os.listdir(tmpdir)[0]) + os.chdir(subdir) + log.warn('Now working in %s', subdir) + yield + + finally: + os.chdir(old_wd) + shutil.rmtree(tmpdir) + + +def _do_download(version, download_base, to_dir, download_delay): + egg = os.path.join(to_dir, 'setuptools-%s-py%d.%d.egg' + % (version, sys.version_info[0], sys.version_info[1])) + if not os.path.exists(egg): + archive = download_setuptools(version, download_base, + to_dir, download_delay) + _build_egg(egg, archive, to_dir) + sys.path.insert(0, egg) + + # Remove previously-imported pkg_resources if present (see + # https://bitbucket.org/pypa/setuptools/pull-request/7/ for details). + if 'pkg_resources' in sys.modules: + del sys.modules['pkg_resources'] + + import setuptools + setuptools.bootstrap_install_from = egg + + +def use_setuptools(version=DEFAULT_VERSION, download_base=DEFAULT_URL, + to_dir=os.curdir, download_delay=15): + to_dir = os.path.abspath(to_dir) + rep_modules = 'pkg_resources', 'setuptools' + imported = set(sys.modules).intersection(rep_modules) + try: + import pkg_resources + except ImportError: + return _do_download(version, download_base, to_dir, download_delay) + try: + pkg_resources.require("setuptools>=" + version) + return + except pkg_resources.DistributionNotFound: + return _do_download(version, download_base, to_dir, download_delay) + except pkg_resources.VersionConflict as VC_err: + if imported: + msg = textwrap.dedent(""" + The required version of setuptools (>={version}) is not available, + and can't be installed while this script is running.
