### New ```atInit``` IOC Shell Command Added
|
|
|
|
The pull request ```PR #558``` introduces a new IOC shell command `atInit` to EPICS Base, which allows users to schedule arbitrary commands to be executed automatically after the IOC initialization phase (`iocInit`).
|
|
|
|
The module allows you to write better-structured ioc shell files to include in your startup scripts without tracking where iocInit is located (and how IOC is deployed) e.g.:
|
|
- to achieve the best maintainability,
|
|
- to improve writing boot sequences,
|
|
- to improve IOC startup flexibility and scripting capabilities.
|
|
|
|
#### Features
|
|
|
|
- Define commands that run after IOC initialization completes.
|
|
- Overwrites ```autosave``` to ensure proper configuration of the required PV.
|
|
- Supports any valid IOC shell command as an argument.
|
|
- Example usages:
|
|
- `atInit "dbpf <PV> <VAL>"`
|
|
- `atInit "date"`
|
|
|
|
#### Testing
|
|
|
|
- Unit tests have been added to verify:
|
|
- Registration and execution of commands scheduled with `atInit`.
|
|
- Proper handling of empty or invalid commands without crashing the IOC.
|
|
- Execution order and environment variable effects.
