StackStorm/st2 v1.4.0

v1.4.0 - April 18, 2016

on GitHub

Passphrase support for the SSH runner. (improvement)

Improvements to ChatOps deployments of packs via pack deploy [Jon Middleton]

Add extra field to the ActionAlias schema for adapter-specific parameters. (improvement)

Dev environment by default now uses gunicorn to spin API and AUTH processes. (improvement)

Allow user to pass a boolean value for the cacert st2client constructor argument. This way
it now mimics the behavior of the verify argument of the requests.request method.
(improvement)

Add datastore access to Python runner actions via the action_service which is available
to all the Python runner actions after instantiation. (new-feature) #2396 #2511
[Kale Blankenship]

Update st2actions.runners.pythonrunner.Action class so the constructor also takes
action_service as the second argument.

Allow /v1/webhooks API endpoint request body to either be JSON or url encoded form data.
Request body type is determined and parsed accordingly based on the value of
Content-Type header.
Note: For backward compatibility reasons we default to JSON if Content-Type header is
not provided. #2473 [David Pitman]

Bug fixes to allow Sensors to have their own log files. #2487 [Andrew Regan]

Display number of seconds which have elapsed for all the executions which have completed
when using st2 execution get CLI command. (improvement)

Display number of seconds elapsed for all the child tasks of a workflow action when using
st2 execution get CLI command. (improvement)

Various improvements in the linux.wait_for_ssh action:

• Support for password based authentication.
• Support for non-RSA SSH keys.
• Support for providing a non-default (22) SSH server port.
• Support for using default system user (stanley) ssh key if neither password nor
  keyfile parameter is provided.

Support for leading and trailing slashes in the webhook urls. (improvement)

Make sure that the filename, module, funcName and lineno attributes which are
available in the log formatter string contain the correct values. (bug-fix)

Reported by Andrew Regan.

Update matchregex rule criteria operator so it uses "dot all" mode where dot (.)
character will match any character including new lines. Previously * didn't match
new lines. (improvement)

Introduce new matchwildcard rule criteria operator. This operator provides supports for Unix
shell-style wildcards (*, ?). (new feature)

Allow user to pass verbose parameter to linux.rm action. For backward compatibility
reasons it defaults to true. (improvement)

Make sure that sensor container child processes take into account --use-debugger flag passed
to the sensor container. This fixes support for remote debugging for sensor processes. (bug-fix)

Drop deprecated and unused system.admin_users config option which has been replaced with
RBAC.

Add --output and --existing-file options to st2-submit-debug-info. [Kale Blankenship]

Move stream functionality from st2api into a new standalone st2stream service. Similar to
st2api and st2auth, stream is now a standalone service and WSGI app. (improvement)

Allow user to specify a timezone in the CLI client config (~/.st2/config). If the timezone is
specified, all the timestamps displayed by the CLI will be shown in the configured timezone
instead of a default UTC display. (new feature)

Add attachments parameter to the core.sendmail action. (improvement) [Cody A. Ray]

Add --register-setup-virtualenvs flag to the register-content script and st2ctl.
When this flag is provided, Python virtual environments are created for all the registered packs.
This option is to be used with distributed setup where action runner services run on multiple
hosts to ensure virtual environments exist on all those hosts. (new-feature)

Update core.st2.CronTimer so it supports more of the cron-like expressions (a-b, */a,
x,y,z, etc.). (improvement)

Add new regex and iregex rule criteria operator and deprecate matchregex in favor of
those two new operators. (new-feature) [Jamie Evans]

Record failures to enforce rules due to missing actions or parameter validation errors. A
RuleEnforcement object will be created for failed enforcements that do not lead to an
ActionExecution creation. (improvement)

Add support for better serialization of the following parameter types for positional parameters
used in the local and remote script runner actions: integer, float, boolean,
list, object. Previously those values were serialized as Python literals which made
parsing them in the shell scripts very cumbersome. Now they are serialized based on the simple
rules described in the documentation which makes it easy to use just by using simple shell
primitives such as if statements and IFS for lists. (improvement, new feature)

Fix linux.traceroute action. (bug fix)

Fix a bug with positional argument handling in the local script runner. Now the arguments with a
no value or value of None are correctly passed to the script. (bug fix)

Fix rule criteria comparison and make sure that falsy criteria pattern values such as integer
0 are handled correctly. (bug-fix)

Reported by Igor Cherkaev.

Add -v flag (verbose mode) to the st2-run-pack-tests script. (improvement)

The list of required and optional configuration arguments for the LDAP auth backend has changed.
The LDAP auth backend supports other login name such as sAMAccountName. This requires a separate
service account for the LDAP backend to query for the DN related to the login name for bind to
validate the user password. Also, users must be in one or more groups specified in group_dns to
be granted access.

Mistral has deprecated the use of task name (i.e. $.task1) to reference task result. It is
replaced with a task function that returns attributes of the task such as id, state, result,
and additional information (i.e. task(task1).result).

Add support for additional SSH key exchange algorithms to the remote runner via upgrade to
paramiko 1.16.0. (new feature)

Add initial code framework for writing unit tests for action aliases. For the usage, please refer
to the "Pack Testing" documentation section. (new feature)

For consistency rename deploy_pack alias to pack_deploy.

Fix alias executions API endpoint and make sure an exception is thrown if the user provided
command string doesn't match the provided format string. Previously, a non-match was silently
ignored. (bug fix)

Add custom use_none Jinja template filter which can be used inside rules when invoking an
action. This filter ensures that None values are correctly serialized and is to be used when
TriggerInstance payload value can be None and None is also a valid value for a particular
action parameter. (improvement, workaround)
