Compatibility Concerns

  • #17244 [!] sched/event: removed event_tickwait_wait() and added TSTATE_WAIT_EVENT This PR contains breaking changes for event implementation to improve its performance, safety and make its api cleaner and easier to use Change summary: Refactors the event module by removing its dependency on semaphores and separate wait objects, and introduces a new task state TSTATE_WAIT_EVENT to simplify scheduling and improve maintainability. Details:
    1. Remove semaphore dependency Reason:
      • Semaphore objects consume more memory than necessary for event synchronization.
      • Semaphore interfaces are relatively complex, involving global locks and logic that exceeds the needs of the event mechanism. Benefit:
      • Simplifies the event module and reduces runtime and memory overhead.
    2. Remove wait object dependency Reason:
      • Wait objects introduce additional memory usage.
      • The current design either uses a local wait object in the waiting task (which is unsafe because the posting task also accesses it) or requires users to define global wait objects and call event_tickwait_wait(). This leads to complicated and error-prone usage.
      • By removing wait objects, the event module can be implemented more cleanly. Benefit:
      • Simplifies API usage.
      • Improves safety and code maintainability.
    3. Introduce TSTATE_WAIT_EVENT and move the scheduling list to the event object Reason:
      • Makes the event module implementation more concise.
      • Allows the scheduler to handle tasks blocked on events more flexibly in special cases (e.g., task deletion). Benefit:
      • Improves modularity and better integrates event handling with the scheduler. Impact

    This change streamlines the event mechanism by eliminating unnecessary abstractions, reducing memory footprint, and improving the clarity of both the implementation and external API, no impact to other nuttx functions
