StackStorm/st2 v2.1.0

v2.1.0 - December 05, 2016

on GitHub

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

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)

Actually validate pack metadata file when registering packs. (bug fix, improvement)

Improve pack validation - now when the packs are registered we require that
"version" attribute in the pack metadata file matches valid semver format and we also require
that "email" attribute (if specified) contains a valid email address. (improvement)

For consistency with new pack name validation changes, sample hello-st2 pack has been renamed
to hello_st2.

Add new stackstorm_version and system fields to the pack.yaml metadata file. Value of the
first field can contain a specific for StackStorm version with which the pack is designed to work
with (e.g. >=1.6.0,<2.2.0 or >2.0.0). This field is checked when installing / registering
a pack and installation is aborted if pack doesn't support StackStorm version which is currently
running. Second field can contain an object with optional system / OS level dependencies.
(new feature)

Require pack metadata version attribute to contain a valid semver version identifier (e.g
0.1.0, 2.0.0, etc.). If version identifier is invalid, pack registration will fail.
(improvement)

When a policy cancels a request due to concurrency, it leaves end_timestamp set to None which
the notifier expects to be a date. This causes an exception in "isotime.format()". A patch was
released that catches this exception, and populates payload['end_timestamp'] with the equivalent
of "datetime.now()" when the exception occurs.

Adding check for datastore Client expired tokens used in sensor container

Add new contributors field to the pack metadata file. This field can contain a list of
people who have contributed to the pack. The format is Name <email>, e.g.
Tomaz Muraus <tomaz@stackstorm.com> (new feature)

Update packs.install action (pack install command) to only load resources from the packs
which are being installed. Also update it and remove "restart sensor container" step from the
install workflow. This step hasn't been needed for a while now because sensor container
dynamically reads a list of available sensors from the database and starts the sub processes.
(improvement)

Change st2api so that a full execution object is returned instead of an error message, when an
API client requests cancellation of an execution that is already canceled

Remove packs.info action because .gitinfo file has been deprecated with the new pack
management approach. Now pack directories are actual checkouts of the corresponding pack git
repositories so this file is not needed anymore.

Speed up short-lived Python runner actions by up to 70%. This way done by re-organizing and
re-factoring code to avoid expensive imports such as jsonschema, jinja2, kombu and mongoengine
in the places where those imports are not actually needed and by various other optimizations.
(improvement)

Add new st2-validate-pack-config tool for validating config file against a particular config
schema file. (new-feature)

Upgrade various internal Python library dependencies to the latest stable versions (gunicorn,
kombu, six, appscheduler, passlib, python-gnupg, semver, paramiko, python-keyczar, virtualenv).

Improve performance of GET /executions/views/filters by creating additional indexes on
executions collection

Add support for default values and dynamic config values for nested config objects. (new feature,
improvement)

Throw a more user-friendly exception if rendering a dynamic configuration value inside the config
fails. (improvement)

Add support for ssh config file for ParamikoSSHrunner. Now ssh_config_file_path can be set
in st2 config and can be used to access remote hosts when use_ssh_config is set to
True. However, to access remote hosts, action paramters like username and
password/private_key, if provided with action, will have precedence over the config file
entry for the host. #2941 #3032 #3058 Eric Edgar

Fix packs.uninstall action so it also deletes configs and policies which belong to
the pack which is being uninstalled. (bug fix)

Fix python action runner actions and make sure that modules from st2common/st2common/runners
directory don't pollute PYTHONPATH for python runner actions. (bug fix)
