Changelog

in development

  • Refactor retries in the Mistral action runner to use exponential backoff. Configuration options for Mistral have changed. (improvement)
  • Add SSH bastion host support to the paramiko SSH runner. Utilizes same connection parameters as the targeted box. (new feature, improvement) #2144, #2150 [Logan Attwood]
  • Update action chain runner so it performs on-success and on-error task name validation during pre_run time. This way common errors such as typos in the task names can be spotted early on since there is no need to wait for the run time.
  • Change headers and params core.http action paramer type from string to object.
  • Don't allow action parameter type attribute to be an array since rest of the code doesn't support parameters with multiple types. (improvement)
  • Fix trigger parameters validation for system triggers during rule creation - make sure we validate the parameters before creating a TriggerDB object. (bug fix)
  • Update local runner so all the commands which are executed as a different user and result in using sudo set $HOME variable to the home directory of the target user. (improvement)
  • Fix a bug with a user inside the context of the live action which was created using alias execution endpoint incorrectly being set to the system user (stanley) instead of the authenticated user which triggered the execution. (bug fix)
  • Include state_info for Mistral workflow and tasks in the action execution result. (improvement)
  • Introduce a new timeout action execution status which represents an action execution timeout. Previously, executions which timed out had status set to failure. Keep in mind that timeout is just a special type of a failure. (new feature)
  • --debug flag no longer implies profiling mode. If you want to enable profiling mode, you need to explicitly pass --profile flag to the binary. To reproduce the old behavior, simply pass both flags to the binary - --debug --profile.
  • Fix policy loading and registering - make sure we validate policy parameters against the parameters schema when loading / registering policies. (bug fix, improvement)
  • Fix policy trigger for action execution cancellation. (bug fix)
  • Improve error reporting for static error in ActionChain definition e.g. incorrect reference in default etc. (improvement)
  • Fix action chain so it doesn't end up in an infinite loop if an action which is part of the chain is canceled. (bug fix)
  • Allow jinja templating to be used in message and data field for notifications.(new feature)
  • Add tools for purging executions (also, liveactions with it) and trigger instances older than certain UTC timestamp from the db in bulk.
  • Fix json representation of trace in cli. (bug fix)

1.1.1 - November 13, 2015

  • Improve speed of st2 execution list command by not requesting result and trigger_instance attributes. The effect of this change will be especially pronounced for installations with a lot of large executions (large execution for this purpose is an execution with a large result).
  • Improve speed of st2 execution get command by not requesting result and trigger_instance attributes.
  • Now when running st2api service in debug mode (--debug) flag, all the JSON responses are pretty indented.
  • When using st2 execution list and st2 execution get CLI commands, display execution elapsed time in seconds for all the executions which are currently in "running" state.
  • Fix a race condition in sensor container where a sensor which takes <= 5 seconds to shut down could be respawned before it exited. (bug fix) #2187 [Kale Blankenship]
  • Add missing entry for st2notifier service to the logrotate config. (bug fix)
  • Allow action parameter values who's type is object to contain special characters such as . and $ in the parameter value. (bug fix, improvement)
  • Allow user to specify URL which Mistral uses to talk to StackStorm API using mistral.api_url configuration option. If this option is not provided it defaults to the old behavior of using the public API url (auth.api_url setting). (improvement)

1.1.0 - October 27, 2015

  • Add YAQL v1.0 support to Mistral. Earlier versions are deprecated. (improvement)
  • Update CLI so st2 run / st2 execution run and st2 execution re-run commands exit with non-zero code if the action fails. (improvement)
  • Move st2auth service authentication backends to a "repo per backend" model. Backends are now also dynamically discovered and registered which makes it possible to easily create and use custom backends. For backward compatibility reasons, flat_file backend is installed And available by default. (new feature, improvement)
  • New st2auth authentication backend for authenticating against LDAP servers - https://github.com/StackStorm/st2-auth-backend-ldap. (new feature)
  • Default to rule being disabled if the user doesn't explicitly specify enabled attribute when creating a rule via the API or inside the rule metadata file when registering local content (previously it defaulted to enabled).
  • Fix timestamp_lt and timestamp_gt filtering in the /executions API endpoint. Now we return a correct result which is expected from a user-perspective. (bug-fix)
  • Enable Mistral workflow cancellation via st2 execution cancel. (improvement)
  • Make sure that alias execution endpoint returns a correct status code and error message if the referenced action doesn't exist.
  • Allow action-alias to be created and deleted from CLI.
  • Allow user to select keystone backend in the st2auth service. (bug-fix)
  • Fix packs.info action so it correctly exists with a non-zero status code if the pack doesn't exist or if it doesn't contain a valid .gitinfo file. (bug-fix)
  • Fix packs.info action so it correctly searches all the packs base dirs. (bug-fix)
  • Add support for --profile flag to all the services. When this flag is provided service runs in the profiling module which means all the MongoDB queries and query related profile data is logged. (new-feature)
  • Introduce API Keys that do not expire like Authentication tokens. This makes it easier to work with webhook based integrations. (new-feature)
  • Allow user to define trigger tags in sensor definition YAML files. (new feature) #2000 [Tom Deckers]
  • Fix a bug in stdout and stderr consumption in paramiko SSH runner where reading a fixed chunk byte array and decoding it could result in multi-byte UTF-8 character being read half way resulting in UTF-8 decode error. This happens only when output is greater than default chunk size (1024 bytes) and script produces utf-8 output. We now collect all the bytes from channel and only then decode the byte stream as utf-8.
  • Update CLI so it supports caching tokens for different users (it creates a different file for each user). This means you can now use ST2_CONFIG_FILE option without disabling token cache. (improvement)
  • Cleanup timers and webhook trigger definitions once all rules referencing them are removed. (bug-fix)
  • Enable pseudo tty when running remote SSH commands with the paramiko SSH runner. This is done to match existing Fabric behavior. (bug-fix)
  • Fix CLI so it skips automatic authentication if credentials are provided in the config on "auth" command. (bug fix)
  • Strip the last 'r' or 'rn' from both stdout and stderr streams from paramiko and local runner output. This is done to be compatible with fabric output of those streams. (bug-fix)
  • Include parameters when viwewing output an execution on the CLI. (improvement)
  • CLI renders parameters and output as yaml for better readability. (improvement)
  • Set env variables (user provided and system assigned) before running remote command or script action with paramiko. (bug-fix)
  • Fix a bug in Paramiko SSH runner where cwd could just be accessed in sudo mode but cd was outside scope of sudo in the command generated. Now, cd is inside the scope of sudo. (bug-fix)
  • Fix a bug in Paramiko SSH runner where kwargs keys in script arguments were not shell injection safe. For example, kwarg key could contain spaces. (bug-fix)
  • Fix a bug in Paramiko SSH runner where JSON output in stdout or stderr wasn't transformed to object automatically. (bug-fix)
  • Paramiko SSH runner no longer runs a remote command with sudo if local user and remote user differ. (bug-fix)
  • Fix a bug with the CLI token precedence - now the auth token specified as an environment variable or as a command line argument has precedence over credentials in the CLI config. (bug fix)
  • Support versioned APIs for auth controller. For backward compatibility, unversioned API calls get redirected to versioned controllers by the server. (improvement)
  • Add option to verify SSL cert for HTTPS request to the core.http action. (new feature)
  • Update remote runner to include stdout and stderr which was consumed so far when a timeout occurs. (improvement)
  • Fix st2-self-check script to check whether to use http/https when connecting to st2, to disable Windows test by default, and to check test status correctly. (bug-fix)
  • Reduce the wait time between message consumption by TriggerWatcher to avoid latency (improvement)
  • Use exclusive messaging Qs for TriggerWatcher to avoid having to deal with old messages and related migration scripts. (bug-fix)
  • Allow user to specify value for the From field in the sendmail action by passing from parameter to the action. (improvement) [pixelrebel]
  • Allow user to update / reinstall Python dependencies listed in requirements.txt inside the pack virtual environment by passing update=True parameter to packs.setup_virtualenv action or by using new packs.update_virtualenv action. (new feature) [jsjeannotte]
  • Pack on install are now assigned an owner group. The pack_group property allows to pick this value and default is st2packs. (new feature)
  • Make sure sensor container child processes (sensor instance processes) are killed and cleaned up if the sensor container is forcefully terminated (SIGKILL). (bug fix, improvement)

0.13.2 - September 09, 2015

  • Private_key supplied for remote_actions is now used to auth correctly. private_key argument should be the contents of private key file (of user specified in username argument). (bug-fix)
  • Last newline character ('n') is now stripped from stdout and stderr fields in local and remote command/shell runners. (improvement)
  • Fix sensor container service so the config argument is correctly passed to the sensor instances in the system packs. Previously, this argument didn't get passed correctly to the FileWatchSensor from the system linux pack. (bug-fix)
  • Make sure sensor processes correctly pick up parent --debug flag. This makes debugging a lot easier since user simply needs to start sensor container with --debug flag and all the sensor logs with level debug or higher will be routed to the container log. (improvement)

  • Add support for restarting sensors which exit with a non-zero status code to the sensor container. Sensor container will now automatically try to restart (up to 2 times) sensor processes which die with a non-zero status code. (improvement)
  • Support for RabbitMQ cluster. StackStorm works with a RabbitMQ cluster and switches nodes on failover. (feature)
  • Add index to the ActionExecution model to speed up query. (improvement)

v0.6.0 - December 8, 2014

Docs: http://docs.stackstorm.com/0.6.0/

  • Separate virtualenv per pack. (Pythonic sensors and actions use them by default.)
  • Install pip requirements from requiremets.txt in packs by default.
  • Sensors are now run in their own process for isolation.
  • Python Actions are now run in their own process for isolation.
  • Add Sensor and PollingSensor base classes. (Sensors API change is non-backward compatible.)
  • Separate out rules_engine into own process.
  • YAML support for action, rules and chain meta.
  • Add sensor meta support (JSON/YAML) to specify trigger types.
  • Packs default path moves from /opt/stackstorm to /opt/stackstorm/packs/.
  • Webhooks are not part of a sensor. They are now part of core API. (Authentication may be required.)
  • API URLs are now versioned. All the existing paths have been prefixed with /v1 (e.g. /v1/actions).
