Description

Fixes #1479 with deprecation warnings.

Is this user-facing behavior change?

Yes,

  • old graph methods via node handler will still work, but it prints the deprecation warnings. this does not break the user application with backward compatibility. probably after Lyrical Luth turtle, we can remove the old methods.
  • new graph methods via Node class are recommended just like service graph APIs.

Did you use Generative AI?

Yes, Claude Sonnet 4.5.

* Fixes Action.*_async futures never complete (#1308)

Per rclpy:1123 If two seperate client server actions are running in seperate executors the future given to the ActionClient will never complete due to a race condition
This fixes  the calls to rcl handles potentially leading to deadlock scenarios by adding locks to there references

* Remove duplicate future handling from send_goal_async (#1532)

A recent change intended to move this logic into a lock context, but
actually ended up duplicating it instead. This fixes that by removing
the duplicated logic outside of the lock. It also preserves the explicit
typing annotation on the future.

* Use unconditional wait when possible. (#1563)

Previously the max() value of the steady time was used as the default deadline. In some environments this results in overflows in the underlying pthread_cond_timedwait call, which waits for the conditional variable in the events queue implementation. Consequently, this lead to freezes in the executor. Reducing the deadline significantly helped, but using `cv.wait` instead of `cv_.wait_until` seems to be the cleaner solution.
