Changelog

Unreleased

Changed

Bumped Github actions to build and publish container images
Building container images for amd64 and arm64 architectures
Make the entrypoint of the default container image to NOT be an absolute path to be more adaptable from the Kubernetes operator

1.19.0 - 2024-02-20

Changed

[POTENTIALLY BREAKING] Removed the logzero dependency as the package is now not maintained any longer. As all the Chaos Toolkit extensions directly import their loggers as from logzero import loggger the chaos toolkit now manages that logger and inject a fake logzero module into sys.path to replace the logger with the chaostoolkit one. Its behavior is the same with the same color scheme and file support. But at least we won't have to import that package any longer.

Gradually, I will remove the dependency from all extensions. Meanwhile, you can now directly access the Chaos Toolkit logger as:
```
import logging
logger = logging.getLogger("chaostoolkit")
```
Refactored the cli module into sub-packages to help readability of each command. This will be the basis for future work on making some of the commands cleaner and more modern, it will also help when adding new commands
Bumped chaostoolkit-lib to 1.42.0
Moved the logging configuration function to chaostoolkit-lib (requires chaostoolkit-lib 1.42.0)
Upgraded various GH actions so that we upgrade to nodejs 20

Make sure to use latest importlib-metadata package even on Python 3.7

1.15.1 - 2023-04-03

Fixed

As we now depend on recent versions of importlib_metadata we need to abide by its breaking compability changes. Specially at the bottom of the section here. Fixes #279

1.15.0 - 2023-01-29

Added

Support to define the runtime strategies for hypothesis and rollbacks from within the experiment itself. Usng the following block:
```
{
  "runtime": {
      "hypoethesis": {
          "strategy": "after-method-only"
      },
      "rollbacks": {
          "strategy": "always"
      }
  }
}
```
Only one of the two may be set. In all cases, these can be overriden by the CLI corresponding flags.

Changed

Dockerfile now requires --build-arg ctkversion=<version> when building
.github/workflows/release.yaml now uses a retry step for Docker builds to ensure we don't lose a race condition between PyPi and our build step

1.9.1 - 2021-05-31

Changed

Fixed --var and --var-file arguments parsing by addition of missing return into validate_vars function

1.9.0 - 2021-02-18

LAST VERSION SUPPORTING PYTHON 3.5

Changed

Updated build scripts to support latest setuptools to build package properly

1.8.0 - 2021-02-17

Changed

Moved to setup.cfg to manage build

1.7.1 - 2020-11-03

Changed

Pass extra variables down to the runner for substitution chaostoolkit-lib#192

1.7.0 - 2020-09-07

Added

Add the --hypothesis-strategy flag to the run command. It defines how the steady-state hypothesis is applied. One of:
- default is the classic mode where the hypothesis is run before and after the method
- before-method-only runs the hypothesis once only before the method
- after-method-only runs the hypothesis once only after the method. This is useful when you know your environment is not in the appropriate state before the conditions are applied
- during-method-only runs the hypothesis repeatedly during the method but not before nor after
- continously runs the hypothesis repeatedly during the method as well as before and after as usual
Add the --hypothesis-frequency flag to the run command. This flag is only meaningful with --hypothesis-strategy=during-method-only|continously. It takes a floating number indicating how many seconds to wait between two executions of the hypothesis
Add the --fail-fast flag to the run command. This flag is only meaningful with --hypothesis-strategy=during-method-only|continously. If set, this indicates the experiment should be marked as deviating immediately. When not provided, the hypothesis runs until the end of the method without terminating the experiment

Changed

Bump dependency on chaostoolkit-lib to 1.13.0 to support the steady state strategy

1.6.0 - 2020-08-17

Added

The --var and --var-file flags to override values in the configuration, and secrets for var files, blocks of the experiments. They take precedence for inlined values and allow to have data files managed externally to the experiment itself when environment variables are not an option for example. #175

1.5.0 - 2020-07-06

Added

Commands to get/set/remove an entry from the settings as well as show the settings file entirely #65
Rollbacs runtime strategy flag #176

Backwars compatible default strategy to run the rollbacks. This will run unless of a failed probe in the hypothesis or when a control interrupted the experiment (not passing the flag is equivalent to this):
```
$ chaos run --rollback-strategy=default experiment.json
```
Always run the rollbacks:
```
$ chaos run --rollback-strategy=always experiment.json
```
Never run the rollbacks:
```
$ chaos run --rollback-strategy=never experiment.json
```
Run the rollbacks only when deviated:
```
$ chaos run --rollback-strategy=deviated experiment.json
```

1.4.2 - 2020-04-29

Added

New flag --no-verify-tls to chaos run and chaos validatecommands; it disables TLS certificate verification when source is downloaded over a self-signed certificate endpoint.

Changed

Migrates CI/CD from TravisCI to Github Actions
[Potentially breaking] Build the Docker image with a non-root user by default (rootless container). This is a potentially breaking change if you created your own docker image using the chaostoolkit/chaostoolkit as a base image.
Allow validating experiments downloaded from URL: chaos validate http://...

1.4.1 - 2020-02-20

Added

Added build for Python 3.8

Changed

```

Changed

Fixed Dockerfile so the right dependencies are installed at build time
Replaced pkg_resource usage with python 3.8 backport importlib_metadata
Bump chaostoolkit-lib dependency to 1.8.0

1.3.0 - 2019-09-03

Added

Load global controls before we even read the experiments so we can apply them before and after loading the experiment.

1.2.0 - 2018-04-17

Added

Support for structured logging #122

Changed

Moved loading global controls back into run_experiment itself chaostoolkit-lib#116

1.1.0 - 2018-04-17

Added

Bump to Chaos Toolkit library 1.2.0
Allow to declare and load controls from settings so they are globally applied to all your runs chaostoolkit-lib#99

In your settings file, at ~/.chaostoolkit-lib/settings.yaml add, for instance:
```
controls:
my-own-control:
  provider:
    module: mypackage.mycontrole_module
    type: python
```
This will load mypackage/mycontrole_module.py from your PYTHONPATH and use it as a control.
Remove MacOSX build. Way too long for any benefits.
Build against stable Python 3.7
Ensure exit code is set in all cases

1.0.0 - 2018-02-21

0.16.0 - 2018-09-19

Added

0.15.0 - 2018-08-09

Added

a new global flag chaos --settings <path> to explicitely specify the location of the Chaos Toolkit settings file
experiments can now also be loaded from a HTTP(s) resource (with or without auth) as per #53

Changed

by default, the run command will now set the exit code to 1 when the experiment is not successful (interrupted, aborted or failed). This can be bypassed by plugins so they have the opportunity to process the journal as well. In that case, they must set the exit code themselves to play nicely.

0.14.0 - 2018-04-27
