From: Jonathan Rajotte Date: Tue, 13 Apr 2021 18:49:52 +0000 (-0400) Subject: action executor: use an execution context to validate enqueued action before execution X-Git-Tag: v2.13.0-rc1~81 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=72365501d3148ca977a09bad8de0ec51b427bdd8;p=lttng-tools.git action executor: use an execution context to validate enqueued action before execution Problem ====== Let's walk over the following scenario: Trigger my_trigger: condition: ust event a action: start session S At time T, session S exists. At T + 1, the event A is hit. At T + 2, the tracer event notification is received and the work item is queued. Here session S have an id of 1. At T + 3, the session S is destroyed and a new session S is created, with a resulting id of 200. At T +4, the work item is popped from the queue and begin execution and will start session S with an id of 200 instead of the session S id 1 that was present at the queuing phase. We effectively want to assign an execution context to an action at the queuing phase and validate that the execution context is still valid upon actual execution. Solution ===== Instead of iterating over the trigger's actions, we prepare an array of work sub-item (action_work_subitem) that effectively is a flattened and augmented array of the trigger's action. For now only the session id is an action level execution context. Each action handler is responsible of validating the execution context before performing the action.
