StackStorm/st2 v2.10.0 on GitHub

Added

Added notify runner parameter to Orquesta that allows user to specify which task(s) to get
notified on completion.
Add support for task delay in Orquesta workflows. #4459 (new feature)
Add support for task with items in Orquesta workflows. #4400 (new feature)
Add support for workflow output on error in Orquesta workflows. #4436 (new feature)
Added -o and -m CLI options to st2-self-check script, to skip Orquesta and/or Mistral
tests. #4347
Allow user to specify new database.authentication_mechanism config option in
/etc/st2/st2.conf.
By default, SCRAM-SHA-1 is used with MongoDB 3.0 and later and MONGODB-CR (MongoDB Challenge
Response protocol) for older servers.

Add new metadata_file attribute to the following models: Action, Action Alias, Rule, Sensor,
TriggerType. Value of this attribute points to a metadata file for a specific resource (YAML file
which contains actual resource definition). Path is relative to the pack directory (e.g.
actions/my_action1.meta.yaml, aliases/my_alias.yaml, sensors/my_sensor.yaml,
rules/my_rule.yaml, triggers/my_trigger.yaml etc.).
Keep in mind that triggers can be registered in two ways - either via sensor definition file in
sensors/ directory or via trigger definition file in triggers/ directory. If
metadata_file attribute on TriggerTypeDB model points to sensors/ directory it means that
trigger is registered via sensor definition. (new feature) #4445
Add new st2client.executions.get_children method for returning children execution objects for
a specific (parent) execution. (new feature) #4444
Contributed by Tristan Struthers (@trstruth).
Allow user to run a subset of pack tests by utilizing the new -f command line option in the
st2-run-pack-tests script.
For example:
1. Run all tests in a test file (module):
  st2-run-pack-tests -j -x -p contrib/packs/ -f test_action_download
2. Run a single test class
  st2-run-pack-tests -j -x -p contrib/packs/ -f test_action_download:DownloadGitRepoActionTestCase
3. Run a single test class method
  st2-run-pack-tests -j -x -p contrib/packs/ -f test_action_download:DownloadGitRepoActionTestCase.test_run_pack_download
(new feature) #4464

Changed

Redesigned and rewritten the action execution scheduler. Requested executions are put in a
persistent queue for scheduler to process. Architecture is put into place for more complex
execution scheduling. Action execution can be delayed on request. (improvement)
core.http action now supports additional HTTP methods: OPTIONS, TRACE, PATCH, PURGE.

Runner loading code has been updated so it utilizes new "runner as Python package" functionality
which has been introduced in a previous release. This means that the runner loading is now fully
automatic and dynamic.
All the available / installed runners are automatically loaded and registering on each StackStorm
service startup.
This means that st2ctl reload --register-runners flag is now obsolete because runners are
automatically registered on service start up. In addition to that,
content.system_runners_base_path and content.runners_base_paths config options are now
also deprecated and unused.
For users who wish to develop and user custom action runners, they simply need to ensure they are
packaged as Python packages and available / installed in StackStorm virtual environment
(/opt/stackstorm/st2). (improvement) #4217
Old runner names which have been deprecated in StackStorm v0.9.0 have been removed (run-local,
run-local-script, run-remote, run-remote-script, run-python, http-runner). If you are still using
actions which reference runners using old names, you need to update them to keep it working.
#4217
Update various CLI commands to only retrieve attributes which are displayed in the CLI from the
API (st2 execution list, st2 execution get, st2 action list, st2 rule list,
st2 sensor list). This speeds up run-time and means now those commands now finish faster.
If user wants to retrieve and view all the attributes, they can use --attr all CLI command
argument (same as before). (improvement) #4396
Update various internal dependencies to latest stable versions (greenlet, pymongo, pytz,
stevedore, tooz). #4410
Improve st2.conf migration for the new services by using prod-friendly logging settings by default #4415
Refactor Orquesta workflow to output on error. Depends on PR
StackStorm/orquesta#101 and StackStorm/orquesta#102
(improvement)
Rename st2client.liveactions to st2client.executions. st2client.liveactions already
represented operations on execution objects, but it was incorrectly named.
For backward compatibility reasons, st2client.liveactions will stay as an alias for
st2client.executions and continue to work until it's fully removed in a future release.

Fixed

st2 login CLI commands now exits with non zero exit code when login fails due to invalid
credentials. (improvement) #4338
Fix st2 key load that errors when importing an empty file #43
Fixed warning in st2-run-pack-tests about invalid format for pip list. (bug fix)
Contributed by Nick Maludy (Encore Technologies). #4380
Fix a bug with st2 execution get / st2 run CLI command throwing an exception if the
result field contained a double backslash string which looked like an unicode escape sequence.
CLI incorrectly tried to parse that string as unicode escape sequence.
Reported by James E. King III @jeking3 (bug fix) #4407
Fix a bug so timersengine config section in st2.conf has precedence over timer
section if explicitly specified in the config file.
Also fix a bug with default config values for timer section being used if user only
specified timersengine section in the config. Previously user options were incorrectly
ignored in favor of the default values. (bug fix) #4424
st2 pack install -j now only spits JSON output. Similarly, st2 pack install -y only spits
YAML output. This change would enable the output to be parsed by tools.
The behavior of st2 pack install hasn't changed and is human friendly. If you want to get meta
information about the pack as JSON (count of actions, sensors etc), you should rely on already
existing st2 pack show -j.

Fix string operations on unicode data in Orquesta workflows, associated with PR
StackStorm/orquesta#98. (bug fix)
Fix access to st2 and action context in Orquesta workflows, associated with PR
StackStorm/orquesta#104. (bug fix)
st2ctl reload --register-aliases and st2ctl reload --register-all now spits a warning when
trying to register aliases with no corresponding action registered in the db.
Reported by nzlosh (improvement) #4372.
