3.6.0 - October 29, 2021

Added

• Added possibility to add new values to the KV store via CLI without leaking them to the shell history. [#5164]

• st2.conf is now the only place to configure ports for st2api, st2auth, and st2stream.

We replaced the static .socket sytemd units in deb and rpm packages with a python-based generator for the st2api, st2auth, and st2stream services. The generators will get <ip>:<port> from st2.conf to create the .socket files dynamically. [#5286] and st2-packages#706

Changed

• Modified action delete API to delete action files from disk along with backward compatibility.

From CLI st2 action delete <pack>.<action> will delete only action database entry. From CLI st2 action delete --remove-files <pack>.<action> or st2 action delete -r <pack>.<action> will delete action database entry along with files from disk.

API action DELETE method with {"remove_files": true} argument in json body will remove database entry of action along with files from disk. API action DELETE method with {"remove_files": false} or no additional argument in json body will remove only action database entry. [#5304], [#5351], [#5360]

• Pinned python module networkx to versions between 2.5.1(included) and 2.6(excluded) because Python v3.6 support was dropped in v2.6. Also pinned decorator==4.4.2 (dependency of networkx<2.6) to work around missing python 3.8 classifiers on decorator's wheel. [#5376]

Contributed by @nzlosh

• Add new --enable-profiler flag to all the servies. This flag enables cProfiler based profiler for the service in question and dumps the profiling data to a file on process exit.

This functionality should never be used in production, but only in development environments or similar when profiling code. [#5199]

Contributed by @Kami.

• Add new --enable-eventlet-blocking-detection flag to all the servies. This flag enables eventlet long operation / blocked main loop logic which throws an exception if a particular code blocks longer than a specific duration in seconds.

This functionality should never be used in production, but only in development environments or similar when debugging code. [#5199]

• Silence pylint about dev/debugging utility (tools/direct_queue_publisher.py) that uses pika because kombu doesn't support what it does. If anyone uses that utility, they have to install pika manually. [#5380]

• Fixed version of cffi as changes in 1.15.0 meant that it attempted to load libffi.so.8. [#5390]

• Updated Bash installer to install latest RabbitMQ version rather than out-dated version available in OS distributions.

Fixed

• Correct error reported when encrypted key value is reported, and another key value parameter that requires conversion is present. [#5328] Contributed by @amanda11, Ammeon Solutions

• Make update_executions() atomic by protecting the update with a coordination lock. Actions, like workflows, may have multiple concurrent updates to their execution state. This makes those updates safer, which should make the execution status more reliable. [#5358]

Contributed by @khushboobhatia01

• Fix "not iterable" error for output_schema handling. If a schema is not well-formed, we ignore it. Also, if action output is anything other than a JSON object, we do not try to process it any more. output_schema will change in a future release to support non-object output. [#5309]

Contributed by @guzzijones

• core.inject_trigger: resolve trigger payload shadowing by deprecating trigger param in favor of trigger_name. trigger param is still available for backwards compatibility, but will be removed in a future release. [#5335] and [#5383]
