The mode executor can run land mode which updates the home position to the landing location. This
can be not the desirable behavior and the home position should stay at the original location.
A flag is added to the configuration overrides to control if the home position is updated or not.
Some modes should only be run within the context of a mode executor and the user should not be able
to select them in the GCS. With this change, the external component registration request can be
used to set if a mode is selectable or not.
There were a number of cases where the state was not correct or not as
desired after disarming, when running an external mode 'MyMission' with
executor:
- run MyMission, which triggers Hold, then Land
- before: Mode: Hold, executor_in_charge: 1
- after: Mode: MyMission, executor_in_charge: 1
- run MyMission, then user switches to RTL
- before: Mode: MyMission, executor_in_charge: 0
- after: Mode: MyMission, executor_in_charge: 1
- run MyMission, then while in Hold mode, low battery failsafe (RTL)
- before: Mode: Hold, executor_in_charge: 1
- after: Mode: MyMission, executor_in_charge: 1
- run MyMission, then stop external mode (terminate the process)
- before: Mode: (mode not available), executor_in_charge: 0
- after: Mode: Hold, executor_in_charge: 0
This case is unchanged:
- run MyMission, then low battery failsafe (RTL)
- before: Mode: MyMission, executor_in_charge: 1
- after: Mode: MyMission, executor_in_charge: 1
There was a race condition: for example when an external mode disabled
failsafe deferring, that then triggered a failsafe, while the mode executor
immediately sends a command (to e.g. switch modes).
In that case the failsafe got triggered but the mode switch was still
allowed.
This was because of the processing ordering:
- mode updates (and propagating the failsafe_action_active state)
- failsafe updates
- command handling
This patch makes sure failsafe_action_active is set immediately after
updating the failsafes.
