Changelog

In development

  • Add new POST /v1/actionalias/match API endpoint which allows users to perform ChatOps action alias matching server-side. This makes it easier to build and maintain StackStorm ChatOps clients / adapters for various protocols and mediums. Clients can now be very thin wrappers around this new API endpoint.

    Also add two new corresponding CLI commands - st2 alias-execution match and st2 alias-execution execute. (new feature) #2895

    Contributed by Anthony Shaw

  • Only allow valid word characters (a-z, 0-9 and _) to be used for action parameter names. Previously, due to bug in the code, any character was allowed.

    If you have an existing action definition which uses parameter with an invalid character, the parameter name needs to be adjusted otherwise action registration will fail. (bug fix, improvement)

  • Adding ability to pass complex array types via CLI by first trying to seralize the array as JSON and then falling back to comma separated array.

  • Add new core.pause action. This action behaves like sleep and can be used inside the action chain or Mistral workflows where waiting / sleeping is desired before proceeding with a next task. (new feature) #2933

    Contribution by Paul Mulvihill.

  • Improve API exception handling and make sure 400 status code is returned instead of 500 on mongoengine field validation error. (improvement)

  • Allow user to supply multiple resource ids using ?id query parameter when filtering "get all" API endpoint result set (e.g. ?id=1,2,3,4). This allows for a better client and servers performance when user is polling and interested in multiple resources such as polling on multiple action executions.(improvement)

2.0.1 - September 30, 2016

  • Fix st2 execution get command so now --attr argument correctly works with child properties of the result and trigger_instance dictionary (e.g. --attr result.stdout result.stderr). (bug fix)
  • Update traces list API endpoint and st2 trace list so the traces are sorted by start_timestamp in descending order by default. This way it's consistent with executions list and -n CLI parameter works as expected. (improvement)
  • Allow users to specify sort order when listing traces using the API endpoint by specifying ?sort_desc=True|False query parameters and by passing --sort=asc|desc parameter to the st2 trace list CLI command. (improvement)
  • Fix a bug with action default parameter values not supporting Jinja template notation for parameters of type object. (bug fix, improvement)
  • Fix --user / -u argument in the st2 key delete CLI command.
  • Retry connecting to RabbitMQ on services start-up if connecting fails because of an intermediate network error or similar. (improvements)
  • Allow jinja expressions {{st2kv.system.foo}} and {{st2kv.user.foo}} to access datastore items from workflows, actions and rules. This is in addition to supporting expressions {{system.foo}} and {{user.foo}}. In subsequent releases, the expressions {{system.}} and {{user.}} will be deprecated. It is recommended to switch to using {{st2kv.system.}} and {{st2kv.user.}} for your content. (improvement)

2.0.0 - August 31, 2016

  • Implement custom Jinja filter functions to_json_string, to_yaml_string, to_human_time_from_seconds that can be used in actions and workflows. (improvement)

  • Refactor Jinja filter functions into appropriate modules. (improvement)

  • Default chatops message to include time taken to complete an execution. This uses to_human_time_from_seconds function. (improvement)

  • Fix a bug when jinja templates with filters (for example, st2 run core.local cmd='echo {{"1.6.0" | version_bump_minor}}') in parameters wasn't rendered correctly when executing actions. (bug-fix)

  • Allow user to cancel multiple executions using a single invocation of st2 execution cancel command by passing multiple ids to the command - st2 execution cancel <id 1> <id 2> <id n> (improvement)

  • We now execute --register-rules as part of st2ctl reload. PR raised by Vaishali: StackStorm#2861 (comment)

  • Bump default timeout for packs.load command from 60 to 100 seconds. (improvement)

  • Change Python runner action and sensor Python module loading so the module is still loaded even if the module name clashes with another module which is already in PYTHONPATH (improvement)

  • Fix validation of the action parameter type attribute provided in the YAML metadata. Previously we allowed any string value, now only valid types (object, string, number, integer, array, null) are allowed. (bug fix)

  • Upgrade pip and virtualenv libraries used by StackStorm pack virtual environments to the latest versions (8.1.2 and 15.0.3).

  • Allow user to list and view rules using the API even if a rule in the database references a non-existent trigger. This shouldn't happen during normal usage of StackStorm, but it makes it easier for the user to clean up in case database ends up in a inconsistent state. (improvement)

  • Update packs.uninstall command to print a warning message if any rules in the system reference a trigger from a pack which is being uninstalled. (improvement)

  • Fix disabling and enabling of a sensor through an API and CLI. (bug-fix)

  • Fix HTTP runner so it works correctly when body is provided with newer versions of requests library (>= 2.11.0). (bug-fix) #2880

    Contribution by Shu Sugimoto.

1.6.0 - August 8, 2016

  • Upgrade to pymongo 3.2.2 and mongoengine 0.10.6 so StackStorm now also supports and works with MongoDB 3.x. (improvement)
  • Make sure policies which are disabled are not applied. (bug fix) Reported by Brian Martin.
  • Allow user to specify an action which is performed on an execution (delay, cancel) when a concurrency policy is used and a defined threshold is reached. For backward compatibility, delay is a default behavior, but now user can also specify cancel and an execution will be canceled instead of delayed when a threshold is reached.
  • Update action runner to use two internal green thread pools - one for regular (non-workflow) and one for workflow actions. Both pool sizes are user-configurable. This should help increase the throughput of a single action runner when the system is not over-utilized. It can also help prevent deadlocks which may occur when using delay policies with action-chain workflows. (improvement)
  • Update CLI commands to make sure that all of them support --api-key option. (bug-fix)
  • Add support for sorting execution list results, allowing access to oldest items. (improvement)
  • Allow administrator to configure maximum limit which can be specified using ?limit query parameters when making API calls to get all / list endpoints. For backward compatibility and safety reasons, the default value still is 100. (improvement)
  • Update st2-register-content script to exit with non-zero on failure (e.g. invalid resource metadata, etc.) by default. For backward compatibility reasons, --register-fail-on-failure flag was left there, but it now doesn't do anything since this is the default behavior. For ease of migrations, users can revert to the old behavior by using new --register-no-fail-on-failure flag. (improvement)
  • Allow Python runner actions to return execution status (success, failure) by returning a tuple from the run() method. First item in the tuple is a flag indicating success (True / False) and the second one is the result. Previously, user could only cause action to fail by throwing an exception or exiting which didn't allow for a result to be returned. With this new approach, user can now also return an optional result with a failure. (new feature)
  • Include a chatops alias sample in examples pack that shows how to use format option to display chatops messages in custom formatted way. (improvement)
  • Fix Internal Server Error when an undefined jinja variable is used in action alias ack field. We now send a http status code 201 but also explicitly say we couldn't render the ack field. The ack is anyways a nice-to-have message which is not critical. Previously, we still kicked off the execution but sent out Internal Server Error which might confuse the user whether execution was kicked off or not. (bug-fix)
  • Include testing for chatops format_execution_result python action. The tests cover various action types. (improvement)
  • Include a field elapsed_seconds in execution API response for GET calls. The clients using the API can now use elapsed_seconds without having to repeat computation. (improvement)
  • Update st2-register-content script so it validates new style configs in /opt/stackstorm/configs/ directory when using --register-configs flag if a pack contains a config schema (config.schema.yaml). (improvement)
  • Implement custom YAQL function st2kv in Mistral to get key-value pair from StackStorm's datastore. (new-feature)

1.5.1 - July 13, 2016

  • Fix trigger registration when using st2-register-content script with --register-triggers flag. (bug-fix)
  • Fix an issue with CronTimer sometimes not firing due to TriggerInstance creation failure. (bug-fix) Reported by Cody A. Ray
  • Add support for default values when a new pack configuration is used. Now if a default value is specified for a required config item in the config schema and a value for that item is not provided in the config, default value from config schema is used. (improvement)
  • Allow user to prevent execution parameter merging when re-running an execution by passing ?no_merge=true query parameter to the execution re-run API endpoint. (improvement)
  • Add support for posixGroup to the enterprise LDAP auth backend. (improvement, bug-fix)

1.5.0 - June 24, 2016

  • SSL support for mongodb connections. (improvement)
  • TriggerInstances now have statuses to help track if a TriggerInstance has been processed, is being processed or failed to process. This bring out some visibility into parts of the TriggerInstance processing pipeline and can help identify missed events. (new-feature)
  • Allow user to enable service debug mode by setting system.debug config file option to True. Note: This is an alternative to the existing --debug CLI flag which comes handy when running API services under gunicorn. (improvement)
  • Fix for data is dropped if message is not present in notification. (bug-fix)
  • Remove now deprecated Fabric based remote runner and corresponding ssh_runner.use_paramiko_ssh_runner config option. (cleanup)
  • Fix support for password protected private key files in the remote runner. (bug-fix)
  • Allow user to provide a path to the private SSH key file for the remote runner private_key parameter. Previously only raw key material was supported. (improvement)
  • Add new API endpoint and corresponding CLI commands (st2 runner disable <name>, st2 runner enable <name>) which allows administrator to disable (and re-enable) a runner. (new feature)
  • Add RBAC support for runner types API endpoints. (improvement)
  • Allow register-setup-virtualenvs flag to be used in combination with register-all in the st2-register-content script.
  • Add get_fixture_content method to all the base pack resource test classes. This method enforces fixture files location and allows user to load raw fixture content from a file on disk. (new feature) future, pack configs will be validated against the schema (if available). (new feature)
  • Add data model and API changes for supporting user scoped variables. (new-feature, experimental)
  • Add missing pytz dependency to st2client requirements file. (bug-fix)
  • Fix datastore access on Python runner actions (set ST2_AUTH_TOKEN and ST2_API_URL env variables in Python runner actions to match sensors). (bug-fix)
  • Remove support for JSON format for resource metadata files. YAML was introduced and support for JSON has been deprecated in StackStorm v0.6. Now the only supported metadata file format is YAML.
  • Add -y / --yaml flag to the CLI list and get commands. If this flag is provided, command response will be formatted as YAML. (new feature)
  • Alias names are now correctly scoped to a pack. This means the same name for alias can be used across different packs. (bug-fix)
  • Ability to migrate api keys to new installs. (new feature)
  • Introduce a new concept of pack config schemas. Each pack can now contain a config.schema.yaml file. This file can contain an optional schema for the pack config. In the
  • Introduce support for pack configs which are located outside of the pack directory in /opt/stackstorm/configs/<pack name>.yaml files. Those files are similar to the existing pack configs, but in addition to the static values they can also contain dynamic values. Dynamic value is a value which contains a Jinja expression which is resolved to the datastore item during run-time. (new feature)
  • Fix a regression in filtering rules by pack with CLI. (bug-fix)
  • Make sure st2-submit-debug-info cleans up after itself and deletes a temporary directory it creates. (improvement) #2714 [Kale Blankenship]
  • Fix string parameter casting - leave actual None value as-is and don't try to cast it to a string which would fail. (bug-fix, improvement)
  • Allow administrator user who's context will be used when running an action or re-running an action execution. (new feature)
  • Add a work-around for trigger creation which would case rule creation for CronTrigger to fail under some circumstances. (workaround, bug-fix)
  • Store action execution state transitions (event log) in the log attribute on the ActionExecution object. (new feature)
  • Make sure -a all / --attr=all flag works for st2 execution list command (bug-fix)
  • Lazily establish SFTP connection inside the remote runner when and if SFTP connection is needed. This way, remote runner should now also work under cygwin on Windows if SFTP related functionality (file upload, directory upload, etc.) is not used. (improvement) Reported by Cody A. Ray
  • API and CLI allow rules to be filtered by their enable state. (improvement)
  • Fix SSH bastion host support by ensuring the bastion parameter is passed to the paramiko ssh client. (bug-fix) #2543 [Adam Mielke]
  • Send out a clear error message when SSH private key is passphrase protected but user fails to supply passphrase with private_key when running a remote SSH action. (improvement)
  • Admins will now be able pass --show-secrets when listing api keys to get the key_hash un-masked on the CLI. (new-feature)
  • Add --register-triggers flag to the st2-register-content script and st2ctl. When this flag is provided, all triggers contained within a pack triggers directory are registered, consistent with the behavior of sensors, actions, etc. This feature allows users to register trigger types outside the scope of the sensors. (new-feature) [Cody A. Ray]

1.4.0 - April 18, 2016

  • 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)

1.3.2 - February 12, 2016

  • Remove get_open_ports action from Linux pack.

1.3.1 - January 25, 2016

  • Make sure setup.py of st2client package doesn't rely on functionality which is only available in newer versions of pip.
  • Fix an issue where trigger watcher cannot get messages from queue if multiple API processes are spun up. Now each trigger watcher gets its own queue and therefore there are no locking issues. (bug-fix)
  • 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)

1.3.0 - January 22, 2016

  • Allow user to pass env parameter to packs.setup_virtualenv and packs.install action.

    This comes handy if user wants pip to use an HTTP(s) proxy (HTTP_PROXY and HTTPS_PROXY environment variable) when installing pack dependencies. (new feature)

  • Ability to view causation chains in Trace. This helps reduce the noise when using Trace to identify specific issues. (new-feature)

  • Filter Trace components by model types to only view ActionExecutions, Rules or TriggerInstances. (new-feature)

  • Include ref of the most meaningful object in each trace component. (new-feature)

  • Ability to hide trigger-instance that do not yield a rule enforcement. (new-feature)

  • Change the rule list columns in the CLI from ref, pack, description and enabled to ref, trigger.ref, action.ref and enabled. This aligns closer the UI and also brings important information front and center. (improvement)

  • Action and Trigger filters for rule list (new-feature)

  • Add missing logrotate config entry for st2auth service. #2294 [Vignesh Terafast]

  • Support for object already present in the DB for st2-rule-tester (improvement)

  • Add --register-fail-on-failure flag to st2-register-content script. If this flag is provided, the script will fail and exit with non-zero status code if registering some resource fails. (new feature)

  • Add a missing get_logger method to the MockSensorService`. This method now returns an instance of Mock class which allows user to assert that a particular message has been logged. [Tim Ireland, Tomaz Muraus]

  • Introduce a new abandoned state that is applied to executions that we cannot guarantee as completed. Typically happen when an actionrunner currently running some executions quits or is killed via TERM.

  • Add new st2garbagecollector service which periodically deletes old data from the database as configured in the config. By default, no old data is deleted unless explicitly configured in the config.

  • All published variables can be available in the result of ActionChain execution under the published property if display_published property is specified.

  • Allow user to specify TTL when creating datastore item using CLI with the --ttl option. (improvement)

  • Fix validation error when None is passed explicitly to an optional argument on action execution. (bug fix)

  • Deprecated params action attribute in the action chain definition in favor of the new parameters attribute. (improvement)

  • Fix action parameters validation so that only a selected set of attributes can be overriden for any runner parameters. (bug fix)

  • Fix type in the headers parameter for the http-request runner. (bug fix)

  • Fix runaway action triggers caused by state miscalculation for mistral workflow. (bug fix)

  • Throw a more friendly error message if casting parameter value fails because the value contains an invalid type or similar. (improvement)

  • Use --always-copy option when creating virtualenv for packs from packs.setup_virtualenv action. This is required when st2actionrunner is kicked off from python within a virtualenv.

  • Fix a bug in the remote script runner which would throw an exception if a remote script action caused a top level failure (e.g. copying artifacts to a remote host failed). (bug-fix)

  • Display execution parameters when using st2 execution get <execution id> CLI command for workflow executions. (improvement)

  • Fix execution cancellation for task of mistral workflow. (bug fix)

  • Fix runaway action triggers caused by state miscalculation for mistral workflow. (bug fix)

  • The --tasks option in the CLI for st2 execution get and st2 run will be renamed to --show-tasks to avoid conflict with the tasks option in st2 execution re-run.

  • Add option to rerun one or more tasks in mistral workflow that has errored. (new-feature)

  • Fix a bug when removing notify section from an action meta and registering it never removed the notify section from the db. (bug fix)

  • Make sure action specific short lived authentication token is deleted immediately when execution is canceled. (improvement)

  • Ignore lock release errors which could occur while reopening log files. This error could simply indicate that the lock was never acquired.

  • Replace chatops.format_result with chatops.format_execution_result and remove dependency on st2 pack from st2contrib.

  • Trace also maintains causation chain through workflows.

1.2.0 - December 07, 2015

  • 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)
  • Introducing noop runner and core.noop action. Returns consistent success in a WF regardless of user input. (new feature)
  • Add missing indexes on trigger_instance_d_b collection. (bug fix)
  • Add mock classes (st2tests.mocks.*) for easier unit testing of the packs. (new feature)
  • Add a script (./st2common/bin/st2-run-pack-tests) for running pack tests. (new feature)
  • Modify ActionAliasFormatParser to work with regular expressions and support more flexible parameter matching. (improvement)
  • Move ChatOps pack to st2 core.
  • Support for formatting of alias acknowledgement and result messages in AliasExecution. (new feature)
  • Support for "representation+value" format strings in aliases. (new feature)
  • Support for disabled result and acknowledgement messages in aliases. (new feature)
  • Add ability to write rule enforcement (models that represent a rule evaluation that resulted in an action execution) to db to help debugging rules easier. Also, CLI bindings to list and view these models are added. (new-feature)
  • Purge tool now uses delete_by_query and offloads delete to mongo and doesn't perform app side explicit model deletion to improve speed. (improvement)

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)

  • 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)

  • 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)
