2024-08-14	py: Add new cstack API for stack checking, with limit margin macro.	Angus Gratton
	Currently the stack limit margin is hard-coded in each port's call to `mp_stack_set_limit()`, but on threaded ports it's fiddlier and can lead to bugs (such as incorrect thread stack margin on esp32). This commit provides a new API to initialise the C Stack in one function call, with a config macro to set the margin. Where possible the new call is inlined to reduce code size in thread-free ports. Intended replacement for `MP_TASK_STACK_LIMIT_MARGIN` on esp32. The previous `stackctrl.h` API is still present and unmodified apart from a deprecation comment. However it's not available when the `MICROPY_PREVIEW_VERSION_2` macro is set. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
2023-05-04	py/stackctrl: Add gcc pragmas to ignore dangling-pointer warning.	Damien George
	This warning became apparent in gcc 13. Signed-off-by: Damien George <damien@micropython.org>
2020-02-28	all: Reformat C and Python source code with tools/codeformat.py.	Damien George
	This is run with uncrustify 0.70.1, and black 19.10b0.
2017-12-11	py/runtime: Move mp_exc_recursion_depth to runtime and rename to raise.	Damien George
	For consistency this helper function is renamed to match the other exception helpers, and moved to their location in runtime.c.
2017-11-29	py: Annotate func defs with NORETURN when their corresp decls have it.	Damien George

2017-10-04	all: Remove inclusion of internal py header files.	Damien George
	Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed.
2017-07-31	all: Use the name MicroPython consistently in comments	Alexander Steffen
	There were several different spellings of MicroPython present in comments, when there should be only one.
2016-06-28	py: Add MP_STATE_THREAD to hold state specific to a given thread.	Damien George

2016-03-07	py/stackctrl: Add mp_stack_set_top() to explicitly set stack top value.	Paul Sokolovsky
	Useful for embedded targets with fixed stack layout.
2015-04-03	vm: Support strict stackless mode, with proper exception reporting.	Paul Sokolovsky
	I.e. in this mode, C stack will never be used to call a Python function, but if there's no free heap for a call, it will be reported as RuntimeError (as expected), not MemoryError.
2015-02-15	stackctrl: Encode "recursion depth exceeded" message as qstr.	Paul Sokolovsky
	So corresponding exception can be thrown even under tight memory conditions.
2015-01-07	py: Put all global state together in state structures.	Damien George
	This patch consolidates all global variables in py/ core into one place, in a global structure. Root pointers are all located together to make GC tracing easier and more efficient.
2015-01-01	py: Move to guarded includes, everywhere in py/ core.	Damien George
	Addresses issue #1022.
2014-12-10	py: Fix function type: () -> (void).	Damien George

2014-08-30	py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h.	Damien George
	Part of code cleanup, working towards resolving issue #50.
2014-07-01	stackctrl: Add "mp_" prefix.	Paul Sokolovsky

2014-06-27	py: Add portable framework to query/check C stack usage.	Paul Sokolovsky
	Such mechanism is important to get stable Python functioning, because Python function calling is handled with C stack. The idea is to sprinkle STACK_CHECK() calls in places where there can be C recursion. TODO: Add more STACK_CHECK()'s.
