With this PR, I can remove the original task.c in picoruby/picoruby and future development will be much easier. ## Add ### General - C API functions exported with MRB_API for external integration: - mrb_execute_proc_synchronously() for synchronous proc execution - Task control APIs (mrb_create_task, mrb_suspend_task, mrb_resume_task, mrb_terminate_task, mrb_stop_task, mrb_task_value, mrb_task_status) - Task context management APIs for picoruby-sandbox (mrb_task_init_context, mrb_task_reset_context, mrb_task_proc_set) - Task.tick class method to get current tick count - Comprehensive C API documentation with WASM integration examples ### For PicoRuby.wasm - WASM/Emscripten support: Disable SIGALRM timer when __EMSCRIPTEN__ is defined, as JavaScript handles tick calls via setInterval - Scheduler lock mechanism to prevent asynchronous task operations during synchronous execution (scheduler_lock counter in mrb_task_state) - mrb_task_run_once() for single-step execution (event loop integration) ## Fix ### task.c - Replace MRB_FIBER_TERMINATED with MRB_TASK_STOPPED just for clarity - Allow suspending DORMANT and WAITING tasks in mrb_task_suspend (See comment in the source) - Task context initialization by removing dummy callinfo push/pop *NOTE* With the dummy callinfo code that I deleted, IRB in PicoRuby ended SEGV. If that code is mandatory, we need to discuss how to solve my problem. ### vm.c - Handle MRB_TASK_CREATED status in VM's NORMAL_RETURN phase to properly stop tasks ---- These changes are necessary to make PicoRuby work. Nevertheless, even with this patch, MicroRuby for Raspberry Pi Pico 2 is still unstable. I would like to merge this PR anyway to make development easier by involving the PicoRuby community.
And refactoring to consolidate duplicate code ref PR #6699
Wrap sync task by mrb_gc_arena_save/restore to release objects from arena that a sync task allocated so that they can be freed in GC cycle
- Fix inconsistency of MRB_API functions and Ruby methods - Get rid of duplication - Adjust error handling
- Add mrb_gc_protect() after arena_restore to prevent result from being collected before returning to caller - Add comment to suspend_task_internal explaining why WAITING and DORMANT tasks can also be suspended - Move argc/argv cast at the beginning of function with comment
