2021-06-19	py/mpstate: Schedule KeyboardInterrupt on main thread.	David Lechner
	This introduces a new macro to get the main thread and uses it to ensure that asynchronous exceptions such as KeyboardInterrupt (CTRL+C) are only scheduled on the main thread. This is more deterministic than being scheduled on a random thread and is more in line with CPython that only allow signal handlers to run on the main thread. Fixes issue #7026.

2021-06-19	py/mpstate: Make exceptions thread-local.	David Lechner
	This moves mp_pending_exception from mp_state_vm_t to mp_state_thread_t. This allows exceptions to be scheduled on a specific thread. Signed-off-by: David Lechner <david@pybricks.com>
2021-05-01	py/scheduler: Add missing MICROPY_WRAP_MP_SCHED_EXCEPTION usage.	Damien George
	This was missed in commit 7cbf826a9575e18ce1b7fe11b0f0997509153260. Signed-off-by: Damien George <damien@micropython.org>
2021-04-30	py/scheduler: Add optional port hook for when something is scheduled.	Damien George
	So that a port can "wake up" when there is work to do. Signed-off-by: Damien George <damien@micropython.org>
2021-04-30	all: Rename mp_keyboard_interrupt to mp_sched_keyboard_interrupt.	Damien George
	To match mp_sched_exception() and mp_sched_schedule(). Signed-off-by: Damien George <damien@micropython.org>
2021-04-30	py/scheduler: Add mp_sched_exception() to schedule a pending exception.	Damien George
	This helper is added to properly set a pending exception, to mirror mp_sched_schedule(), which schedules a function. Signed-off-by: Damien George <damien@micropython.org>
2020-05-08	py/scheduler: Convert mp_sched_full and mp_sched_num_pending to macros.	Damien George
	So they are guaranteed to be inlined within functions like mp_sched_schedule which may be located in a special memory region.
2020-04-30	py/scheduler: Add option to wrap mp_sched_schedule in arbitrary attr.	Damien George
	So ports can put it in a special memory section if needed.
2020-04-13	py/scheduler: Add assert that scheduler is locked when unlocking.	Jim Mussared
	And add a test that shows how this can happen when multiple threads are accessing the scheduler, which fails if atomic sections are not used.
2020-04-13	py/scheduler: Fix race in checking scheduler pending state.	Jim Mussared
	Because the atomic section starts after checking whether the scheduler state is pending, it's possible it can become a different state by the time the atomic section starts. This is especially likely on ports where MICROPY_BEGIN_ATOMIC_SECTION is implemented with a mutex (i.e. it might block), but the race exists regardless, i.e. if a context switch occurs between those two lines.
2020-02-07	py/scheduler: Move clearing of kbd traceback to mp_keyboard_interrupt.	Damien George
	This is a more logical place to clear the KeyboardInterrupt traceback, right before it is set as a pending exception. The clearing is also optimised from a function call to a simple store of NULL.
2020-02-07	py/scheduler: Allow a port to specify attrs for mp_keyboard_interrupt.	Damien George
	Functions like mp_keyboard_interrupt() may need to be called from an IRQ handler and may need to be in a special memory section, so provide a generic wrapping macro for a port to do this. The macro name is chosen to be MICROPY_WRAP_<function name in uppercase> so that (in the future with more wrappers) each function could potentially be handled separately.
2020-02-07	py/scheduler: Move mp_keyboard_interrupt from lib/utils to py core.	Damien George
	This function is tightly coupled to the state and behaviour of the scheduler, and is a core part of the runtime: to schedule a pending exception. So move it there.
2020-02-07	py/scheduler: Add "raise_exc" argument to mp_handle_pending.	Damien George
	Previous behaviour is when this argument is set to "true", in which case the function will raise any pending exception. Setting it to "false" will cancel any pending exception.
2019-07-17	py/scheduler: Rename sched_stack to sched_queue.	Jim Mussared
	Behaviour was changed from stack to queue in 8977c7eb581f5d06500edb1ea29aea5cbda04f28, and this updates variable names to match. Also updates other references (docs, error messages).
2019-03-26	py/scheduler: Convert micropythyon.schedule() to a circular buffer.	Andrew Leech
	This means the schedule operates on a first-in, first-executed manner rather than the current last-in, first executed.
2017-03-20	py: Add micropython.schedule() function and associated runtime code.	Damien George
