* py: Don't include mp_optimise_value or opt_level() if compiler disabled.Damien George2018-04-04
| | | | | | Without the compiler enabled the mp_optimise_value is unused, and the micropython.opt_level() function is not useful, so exclude these from the build to save RAM and code size.
* py/modmicropython: Allow to have stack_use() func without mem_info().Damien George2018-02-20
| | | | | | | | | | | The micropython.stack_use() function is useful to query the current C stack usage, and it's inclusion in the micropython module doesn't need to be tied to the inclusion of mem_info()/qstr_info() because it doesn't rely on any of the code from these functions. So this patch introduces the config option MICROPY_PY_MICROPYTHON_STACK_USE which can be used to independently control the inclusion of stack_use(). By default it is enabled if MICROPY_PY_MICROPYTHON_MEM_INFO is enabled (thus not changing any of the existing ports).
* py: Introduce a Python stack for scoped allocation.Damien George2017-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the MICROPY_ENABLE_PYSTACK option (disabled by default) which enables a "Python stack" that allows to allocate and free memory in a scoped, or Last-In-First-Out (LIFO) way, similar to alloca(). A new memory allocation API is introduced along with this Py-stack. It includes both "local" and "nonlocal" LIFO allocation. Local allocation is intended to be equivalent to using alloca(), whereby the same function must free the memory. Nonlocal allocation is where another function may free the memory, so long as it's still LIFO. Follow-up patches will convert all uses of alloca() and VLA to the new scoped allocation API. The old behaviour (using alloca()) will still be available, but when MICROPY_ENABLE_PYSTACK is enabled then alloca() is no longer required or used. The benefits of enabling this option are (or will be once subsequent patches are made to convert alloca()/VLA): - Toolchains without alloca() can use this feature to obtain correct and efficient scoped memory allocation (compared to using the heap instead of alloca(), which is slower). - Even if alloca() is available, enabling the Py-stack gives slightly more efficient use of stack space when calling nested Python functions, due to the way that compilers implement alloca(). - Enabling the Py-stack with the stackless mode allows for even more efficient stack usage, as well as retaining high performance (because the heap is no longer used to build and destroy stackless code states). - With Py-stack and stackless enabled, Python-calling-Python is no longer recursive in the C mp_execute_bytecode function. The micropython.pystack_use() function is included to measure usage of the Python stack.
* all: Remove inclusion of internal py header files.Damien George2017-10-04
| | | | | | | | | | | | | | | | 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.
* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* py/modmicropython: Cast stack_limit value so it prints correctly.Damien George2017-07-18
| | | | Without this cast the print will give a wrong result on nan-boxing builds.
* py/modmicropython: Add micropython.kbd_intr() function.Damien George2017-04-18
| | | | | | | It controls the character that's used to (asynchronously) raise a KeyboardInterrupt exception. Passing "-1" allows to disable the interception of the interrupt character (as long as a port allows such a behaviour).
* py: Add micropython.schedule() function and associated runtime code.Damien George2017-03-20
|
* py/modmicropython: Add micropython.opt_level([value]) function.Damien George2016-10-11
| | | | This allows to get/set at runtime the optimisation level of the compiler.
* py/modmicropython: Add micropython.const, alias for identity function.Damien George2016-09-27
| | | | | | | | | Having a micropython.const identity function, and writing "from micropython import const" at the start of scripts that use the const feature, allows to write scripts which are compatible with CPython, and with uPy builds that don't include const optimisation. This patch adds such a function and updates the tests to do the import.
* all: Remove 'name' member from mp_obj_module_t struct.Damien George2016-09-22
| | | | One can instead lookup __name__ in the modules dict to get the value.
* py: Add MP_STATE_THREAD to hold state specific to a given thread.Damien George2016-06-28
|
* py/modmicropython: Add stack_use, heap_lock and heap_unlock functions.Damien George2016-01-24
| | | | | | | | | micropython.stack_use() returns an integer being the number of bytes used on the stack. micropython.heap_lock() and heap_unlock() can be used to prevent the memory manager from allocating anything on the heap. Calls to these are allowed to be nested.
* py: Change type signature of builtin funs that take variable or kw args.Damien George2016-01-11
| | | | | With this patch the n_args parameter is changed type from mp_uint_t to size_t.
* py/qstr: Use size_t instead of mp_uint_t when counting allocated bytes.Damien George2015-12-17
|
* py: Add MP_ROM_* macros and mp_rom_* types and use them.Damien George2015-11-29
|
* py: Convert occurrences of non-debug printf to mp_printf.Damien George2015-04-16
|
* py: Use TextIOWrapper only if PY_IO_FILEIO def'd; cast size_t for print.Damien George2015-02-15
|
* py: Add option to micropython.qstr_info() to dump actual qstrs.Damien George2015-02-10
|
* py, unix: Allow to compile with -Wunused-parameter.Damien George2015-01-20
| | | | See issue #699.
* py, unix, lib: Allow to compile with -Wold-style-definition.Damien George2015-01-12
|
* py: Make mem_info print correct remaining stack bytes.Damien George2015-01-09
|
* py: Add MICROPY_PY_MICROPYTHON_MEM_INFO to enable mem-info funcs.Damien George2015-01-09
| | | | | | This allows to enable mem-info functions in micropython module, even if MICROPY_MEM_STATS is not enabled. In this case, you get mem_info and qstr_info but not mem_{total,current,peak}.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* modmicropython: Move mem_info() and qstr_info() functions from unix port.Paul Sokolovsky2014-12-01
| | | | TODO: Merge useful functionality from modpyb too.
* Use MP_DEFINE_CONST_DICT macro to define module dicts.Damien George2014-11-29
| | | | | This is just a clean-up of the code. Generated code is exactly the same.
* py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.Damien George2014-07-31
| | | | Addresses issue #724.
* Add support for storing args during an exception raised by an irq.Dave Hylands2014-07-25
| | | | | | | | | | | | | | | | | The user code should call micropython.alloc_emergency_exception_buf(size) where size is the size of the buffer used to print the argument passed to the exception. With the test code from #732, and a call to micropython.alloc_emergenncy_exception_buf(100) the following error is now printed: ```python >>> import heartbeat_irq Uncaught exception in Timer(4) interrupt handler Traceback (most recent call last): File "0://heartbeat_irq.py", line 14, in heartbeat_cb NameError: name 'led' is not defined ```
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* py: Include mpconfig.h before all other includes.Paul Sokolovsky2014-06-21
| | | | | | It defines types used by all other headers. Fixes #691.
* Prefix ARRAY_SIZE with micropython prefix MP_Emmanuel Blot2014-06-19
|
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
* Add ARRAY_SIZE macro, and use it where possible.Damien George2014-04-26
|
* py: Change module globals from mp_map_t* to mp_obj_dict_t*.Damien George2014-04-05
| | | | | | Towards addressing issue #424. Had a small increase to ROM usage (order 60 bytes).
* Merge map.h into obj.h.Damien George2014-03-30
| | | | | | Pretty much everyone needs to include map.h, since it's such an integral part of the Micro Python object implementation. Thus, the definitions are now in obj.h instead. map.h is removed.
* Proper support for registering builtin modules in ROM.Damien George2014-03-25
Comes with some refactoring of code and renaming of files. All modules are now named mod*.[ch].
