Compatibility Concerns
* [#18083](https://github.com/apache/nuttx/pull/18083) !sched: Fix MISRA-C violations
This pull request consists of a series of commits primarily focused on improving code quality, enhancing type safety, addressing
compilation warnings, and ensuring compliance with MISRA-C coding standards across various subsystems of the NuttX operating system.
Impact
Users (Application Developers): The changes are largely internal and should not affect the functional behavior or the public
POSIX API for applications (e.g., timer_create, sem_wait, clock_gettime). The primary user-facing impact is increased code
reliability and stability due to stricter type checking and error handling.
Code Quality and Maintenance: By addressing MISRA-C violations and eliminating compiler warnings, the codebase becomes more portable,
predictable, and easier to maintain. The refactoring in the timer subsystem (removing early returns, simplifying logic) improves
readability and reduces the risk of latent bugs.
Compatibility: The modifications maintain backward source compatibility. However, developers who directly relied on the internal
nxclock_settime() symbol will need to adapt, as it has been removed.
Documentation: No direct impact on external documentation. The inline comments within the code are updated to reflect some of the logic changes.
Security: While not a direct security patch, the overall hardening (e.g., stricter input validation) contributes to the system's
robustness against potential misuse.
* [#18398](https://github.com/apache/nuttx/pull/18398) !boards: Align naming of Kconfig options for interpreters
Aligns the Kconfig option naming for interpreters. Part of twin PR apache/nuttx-apps#3403 which should be merged first.
BREAKING CHANGE:
All configurations using CONFIG_INTERPRETER_* options will no longer compile due to missing symbol errors.
The fix is very quick: any configurations using this options should add a trailing S following INTERPRETER in the affected Kconfig variables.
I believe ./tools/refresh.sh should also be capable of doing this automatically.
