Prior to this change those workflows would + remain paused until an operator manually resumed each one. + + This adds an automatic bootstrap loop that runs periodically after + engine startup, plus a manual ``st2-bootstrap-workflow`` CLI as an + operator escape hatch. + + **Behavior.** + + * At engine startup, after the initial health check passes, spawn a + bootstrap greenthread that iterates every ``bootstrap_interval`` + seconds (default 900) for up to ``bootstrap_duration`` seconds + (default 3600). Each pass queries LiveActions with + ``status=paused`` and + ``context.paused_by=workflow_engine_start_stop_seq``, filtered by + ``bootstrap_lookback_days`` (default 1 day). For each match, syncs + conductor state and calls ``request_resume``. + * A leader-election lock + (``coordinator.get_lock(WORKFLOW_ENGINE_START_STOP_SEQ)``) ensures + only one engine per bootstrap pass runs the resume — no duplicated + work when multiple engines start together. + * The manual ``st2-bootstrap-workflow `` CLI bypasses + the leader election and the lookback filter. Operators use it when + the automatic loop skipped a workflow (``coordination.service_registry`` + disabled, this engine not the sorted-first member, marker cleared + by a prior crashed attempt, or the bootstrap window elapsed before + the workflow was reached). + + **New service-layer helpers** in ``st2common.services.workflows``: + + * ``sync_completed_tasks_to_conductor(wf_ex_id)`` — walks every + ``TaskExecution`` for the workflow and syncs completed-task status + into conductor state (so the conductor stops thinking a done task + is still running), and re-stages ``RUNNING`` tasks that aren't + currently staged (so ``get_next_tasks()`` finds them). Needed + because tasks that completed or transitioned between "shutdown + started" and "pause fully processed" would otherwise be invisible + to the conductor when resume runs. + * ``bootstrap_resume_execution(lv_ac_db)`` — single-LiveAction + resume helper. Clears the ``paused_by`` marker, calls + ``sync_completed_tasks_to_conductor``, then invokes + ``request_resume``. Called by both the automatic loop and the CLI. + * ``reconcile_running_execution(lv_ac_db)`` — operator-initiated + safety valve for a workflow stuck in ``RUNNING`` (not paused) + because its driving message was lost with a hard-killed engine + (e.g. OOM after ack-on-dispatch but before processing). Reconciles + conductor state from persisted task executions via + ``sync_completed_tasks_to_conductor`` and then re-drives the + workflow with ``request_next_tasks`` (it does not go through + ``request_resume``, which no-ops on already-running workflows). + Exposed only via ``st2-bootstrap-workflow --reconcile-running + ``; it is intentionally not run automatically because + re-driving a workflow a live engine is still processing could + double-request tasks. + + **New config options** under ``[workflow_engine]``: + + * ``bootstrap_enabled`` (default ``False``) — off by default; enable + in clustered/k8s environments where rolling restarts can leave + shutdown-paused workflows behind. + * ``bootstrap_interval`` (default 900) — seconds between passes + inside the bootstrap window. + * ``bootstrap_duration`` (default 3600) — total wall-clock seconds + the loop runs after startup. After this elapses the loop exits and + no further automatic bootstraps run until the next engine start. + * ``bootstrap_lookback_days`` (default 1) — only automatically + bootstrap workflows whose ``LiveAction.start_timestamp`` is within + this window. Prevents accidentally resuming very old paused + workflows. The manual CLI ignores this filter. + + **New shared constant** ``WORKFLOW_ENGINE_START_STOP_SEQ`` moved to + ``st2common.services.workflows`` so the engine, the bootstrap loop, + the shutdown-pause code, and the CLI all reference the same marker + string. + * implemented zstandard compression for parameters and results. #5995 contributed by @guzzijones12 + * removed embedded liveaction in action execution database table #5995 contributed by @guzzijones12 diff --git a/conf/st2.conf.sample b/conf/st2.conf.sample index 27a2eb0a86..61c9b1d03d 100644 --- a/conf/st2.conf.sample +++ b/conf/st2.conf.sample @@ -84,7 +84,7 @@ token_ttl = 86400 # Standalone mode options - options below only apply when auth service is running in the standalone # mode. -# Authentication backend to use in a standalone mode.
