StackStorm/st2 v2.6.0

on GitHub

https://stackstorm.com/2018/01/25/new-year-new-stackstorm-v2-6-released/

Added

• Add new get_user_info method to action and sensor service. With this method, user can
  retrieve information about the user account which is used to perform datastore operations inside
  the action and sensor service. (new feature) #3831

• Add new /api/v1/user API endpoint. This API endpoint is only available to the authenticated
  users and returns various metadata on the authenticated user (which method did the user use to
  authenticate, under which username the user is authenticated, which RBAC roles are assignment to
  this user in case RBAC is enabled, etc.) (new feature) #3831

• The /api/v1/match_and_execute API endpoint matches a single alias and executes multiple times
  if the alias format has a match_multiple key set to true. Please refer to the
  documentation for usage. #3884

• Add ability to share common code between python sensors and python actions. You can now place
  common code inside a lib directory inside a pack (with an __init__.py inside lib
  directory to declare it a python package). You can then import the common code in sensors and
  actions. Please refer to documentation for samples and guidelines. #3490

• Add support for password protected sudo to the local and remote runner. Password can be provided
  via the new sudo_password runner parameter. (new feature) #3867

• Add new --tail flag to the st2 run / st2 action execute and st2 execution re-run
  CLI command. When this flag is provided, new execution will automatically be followed and tailed
  after it has been scheduled. (new feature) #3867

• Added flag --auto-dict to st2 run and st2 execution re-run commands. This flag must now
  be specified in order to automatically convert list items to dicts based on presence of colon
  (:) in all of the list items (new feature) #3909

• Allow user to set default log level used by all the Python runner actions by setting
  actionrunner.pythonrunner```` option in st2.conf`` (new feature) #3929

• Update st2client package which is also utilized by the CLI so it also works under Python 3.

  Note: Python 2.7 is only officially supported and tested Python version. Using Python 3 is at
  your own risk - they are likely still many bugs related to Python 3 compatibility. You have been warned.
  (new feature) #3929 #3932

• Add ?limit=-1 support for the API to fetch full result set (CLI equivalent flag
  --last/-n). Post error message for limit=0 and fix corner case where negative values for
  limit query param were not handled correctly. #3761 #3708 #3735

• Only allow RBAC admins to retrieve all the results at once using ?limit=-1 query param, upate
  the code so api.max_page_size config option only applies to non-admin users, meaning users
  with admin permission can specify arbitrary value for ?limit query param which can also be
  larger than api.max_page_size. (improvement) #3939

• Add new ?include_attributes query param filter to /v1/executions/ API endpoint
  With this filter user can select which fields to include in the response (whitelist approach,
  opposite of the existing ?exclude_attributes filter).

  For example, if you only want to retrieve id and status field, the URL would look like
  this - /v1/executions?include_attributes=id,status. (new feature) #3953 #3858 #3856

Changed

• st2actions.runners.pythonrunner.Action class path for base Python runner actions has been
  deprecated since StackStorm v1.6.0 and will be fully removed in StackStorm v2.7.0. If you have
  any actions still using this path you are encouraged to update them to use
  st2common.runners.base_action.Action path. #3803
• Refactor st2common Python package so it's fully self sustaining and can be used in a
  standalone manner. (improvement) #3803
• Refactor Python action runner so it only depends on st2common Python package (previously it
  also depended on st2actions) and can be used in a standalone mode. Previously pack config and
  and some other parameters were retrieved inside the Python process wrapper, but now they are
  retrieved inside the runner container and passed to the runner. This also makes it easier to add
  support for pack configs to other runners in the future. (improvement) #3803
• Update various Python dependencies to the latest stable versions (kombu, amqp, apscheduler,
  gitpython, pymongo, stevedore, paramiko, prompt-toolkit, flex). #3830
• Mask values in an Inquiry response displayed to the user that were marked as "secret" in the
  inquiry's response schema. #3825
• Real-time action output streaming is now enabled by default. For more information on this
  feature, please refer to the documentation - https://docs.stackstorm.com/latest/reference/action_output_streaming.html.
  You can disable this functionality by setting actionrunner.stream_output config option in
  st2.conf to False and restart the services (sudo st2ctl restart).

Fixed

• Fully fix performance regressions for short Python runner actions introduced in the past and
  partially fixed in #3809. (bug fix) #3803

• Fix 'NameError: name 'cmd' is not defined' error when using linux.service with CentOS systems.
  #3843. Contributed by @shkadov

• Fix bugs with newlines in execution formatter (client) (bug fix) #3872

• Fixed st2ctl status to use better match when checking running process status. #3920

• Removed invalid st2ctl option to re-open Mistral log files. #3920

• Update garbage collection service and st2-purge-executions CLI tool and make deletion more
  efficient. Previously we incorrectly loaded all the execution fields in memory, but there was no
  need for that and now we only retrieve and load id which is the only field we need. #3936
