Changelog

[unreleased]

Added

  • CI jobs for checking compatibility with python 3.13
  • rally task start and rally task validate can now read the task from stdin -- pass - in place of the file name, for example cat task.yaml | rally task start -.

Changed

  • The command-line interface has been rebuilt on typer, replacing the custom argparse/oslo.config wrapper it grew up on. The change is backward compatible for documented usage: every command, option and primary identifier continues to work, and each primary identifier may now also be supplied positionally, for example rally task status <uuid> in addition to rally task status --uuid <uuid>. The only user-visible differences are cosmetic: help and error messages are now rendered by typer, and bash completion no longer lists the primary-id flags (--uuid, --id, --env, --deployment, --task), which still work when typed explicitly.
  • We no longer suppress PyMySQL's connect-time warnings. That workaround only existed to hide the old @@tx_isolation deprecation warning (SQLAlchemy #4120 / PyMySQL #614), which modern SQLAlchemy and PyMySQL have since fixed, so the mysql extra now pins PyMySQL>=0.9.0.
  • The pep8 gate now runs ruff alongside flake8: ruff owns the pycodestyle, pyflakes and import-convention checks, while flake8 keeps the remaining hacking and Rally-specific rules.
  • Scenario run() arguments can be validated and documented from their Python type annotations. See the scenario plugin docs for the supported annotations.
  • A dict scenario argument that is forwarded to another callable can derive its schema from that callable's signature with scenario.ArgsOf(func, ignore=(...)), instead of restating it as a TypedDict.
  • rally plugin show now lists the CONFIG_SCHEMA parameters of any plugin (contexts, runners, SLAs), not only scenarios.
  • The generated plugin reference now surfaces more of a scenario's derived argument schema: default values (rendered as Defaults to ...), which arguments are required, and a note describing the extra **kwargs a scenario accepts.
  • New [DEFAULT]strict_type_annotations option to fail, rather than warn, on a scenario argument type Rally cannot map to a JSON Schema.
  • Resource types (the plugins that convert a task argument into the value a scenario receives, such as a file path into its contents) have been reworked. An argument can be bound to one inline in its annotation with types.Convert("<name>"), and the specification a resource type accepts is now validated and documented from the resource_spec annotation of its pre_process. A resource type may implement a richer keyword-only pre_process(self, *, resource_spec, config, output_type) (with a scenario_cls constructor argument) to resolve a value per iteration by returning a types.DeferredResource or to shape the result to the argument's declared type. These signature changes are backward compatible: the legacy pre_process(resource_spec, config) and __init__(context, cache) forms are detected automatically and keep working, with a deprecation warning. See the resource type plugin docs.

Deprecated

  • The --deployment / --deployment-id options of rally task and rally verify are renamed to --env. The old names still work but now print a deprecation warning -- switch to --env.

Removed

  • The deprecated compatibility shims under rally.plugins.common (the exporters, hook, runners, scenarios, sla and verification subpackages, along with rally.plugins.common.types). Use the rally.plugins.task and rally.plugins.verification packages instead.
  • Support for Python 3.9
  • rally deployment create --fromenv no longer special-cases rally-openstack <= 1.4.0 (it used to drop OS_KEY/https_key for those). That release is ~7 years old and predates every currently supported Python -- old rally-openstack only went up to py37 -- so the shim is gone.

Fixed

  • Publishing to ReadTheDocs
  • Compatibility with paramiko 4+, which dropped the removed DSA key support.
  • The failure during Scenario plugin initialization will no longer be silently ignored. Such failures are now counted as interaction failures.

    Launchpad-bug #1807870

[1.3.0] - 2018-12-01

Added

  • Add the --deployment option to commands rally task report and rally task export that allows to report/export all tasks from defined deployment.

  • Briefly: the new base image is published at Docker Hub Detailed story: Long time ago Rally team introduced first docker images which

    were hosted by rallyforge account at Docker Hub. Due to various circumstances we lost access to that account and Docker support restored access to it in a strange way (we lost all repositories and could not recreate them). That is why Rally team started publishing docker images from scratch. The new organization was created -xRally . Since we already had plans to move OpenStack plugins to the separate repository, we started publishing images with in-tree OpenStack plugins to xrally/xrally-openstack repository. As soon as, a separate package for OpenStack plugins was introduced, we switched the source of xrally/xrally-openstack Docker Hub repository to rally-openstack git repository. As for Rally 1.0.0 we finally have pure framework without heavy dependencies and can start publishing separate images for Rally framework itself which can be used as a base image for all plugins. New images will be located at xrally/xrally Docker Hub repository.

Changed

  • rally --version prints version of Rally framework with versions of installed plugins instead of printing just version of Rally framework.
  • Dockerfile moved from the root directory to ./etc/docker/

Fixed

A floating bug with constant_for_duration runner.

Launchpad-bug #1800447

[1.2.1] - 2018-09-27

Minor inner fixes

[1.2.0] - 2018-09-19

Added

  • New validator map_keys for checking keys of specific argument.
  • Support of ElasticSearch 6.x cluster elastic exporter.

Changed

  • Improved validation errors for task component.
  • [ElasticSearch exporter] Do not send 'no-name-action' index when the item fails after some atomic actions completed and there is a root atomic. For example, there is 'wait-for-some-resource-ready' action. It consists of a bunch of get requests to update the current status. After specified timeout this action can fail if the resource is not in the right state. In such case, there is no reason to use 'no-name-action' for saving the error, the parent index (i.e 'wait-for-some-resource-ready') will already store it.

[1.1.0] - 2018-08-07

Added

  • Introducing rally env cleanup command for performing disaster cleanup.
  • New CI jobs for checking compatibility with Python 3.4, 3.6, 3.7 .

Changed

  • The output of json task result exporter (rally task report --json) is extended with information about environment where task was executed (new env_name and env_uuid properties)
  • Add the --filter-by option to the command rally task detailed, which allows us to show only those workloads which we are interested in (see the examples below). Examples:
    1. show only failed workloads rally task detailed --filter-by sla-failures
    2. show only those workloads which include the next scenario plugin(s) rally task detailed --filter-by scenarios=scenario1[,scenarios2...]
  • requirements and constraints (suggested versions) files are updated.

Removed

  • Disturbing warning message about removing in-tree OpenStack plugins. This message became redundant after Rally 1.0.0 when such plugins were removed.
  • OpenStack related configuration options for sample file.
  • Deprecated in Rally 0.10 rally.task.exporter.Exporter class in favor of rally.task.exporter.TaskExporter.

Fixed

Deprecated

  • 'async' argument of API method task.abort in favor of 'wait' argument which doesn't conflict with a reserved keyword in python 3.7

[1.0.0] - 2018-06-20

It finally happened. We are happy to inform you that OpenStack plugins has a single home - https://github.com/openstack/rally-openstack . All in-tree plugins are removed now and framework part become more lightweight.

What does it mean for you?!

If you are interested only in OpenStack plugins, just change the package you are installing from rally to rally-openstack. If you have custom OpenStack plugins which inherits from upstream, change python imports from rally.plugins.openstack to rally_openstack. That is all.

If you are interested not only in OpenStack, you can start using your favourite tool for various platforms and systems. Here you can find our first attempts to seize the world - https://github.com/xrally/xrally-docker and https://github.com/xrally/xrally-kubernetes.

Changed

Since OpenStack plugins were moved to the separate repository, the new release notes should become light as well, so there is no need in separate pages for each release. All release notes will be aggregated in a single file CHANGELOG.rst.

Also, it is sad to mention, but due to OpenStack policies we need to stop duplicating release notes at git tag message. At least for now.

Removed

  • All OpenStack related plugins.

Fixed

  • Validation of existing platforms in Python 3 environment.
  • Support of testr for verifiers.

[0.0.0] - [0.12.1]
