Andrew Leech 89ff506513 py: Update and rework build system for including external C modules.
How to use this feature is documented in docs/develop/cmodules.rst.
2019-03-08 22:58:42 +11:00
Ayke van Laethem 2e516074da py: Implement a module system for external, user C modules.
This system makes it a lot easier to include external libraries as static,
native modules in MicroPython.  Simply pass USER_C_MODULES (like
FROZEN_MPY_DIR) as a make parameter.

Andrew Leech cf22f4793c py: Allow registration of modules at their definition.
During make, makemoduledefs.py parses the current builds c files for
MP_REGISTER_MODULE(module_name, obj_module, enabled_define)

These are used to generate a header with the required entries for
"mp_rom_map_elem_t mp_builtin_module_table[]" in py/objmodule.c

Yonatan Goldschmidt bc4f8b438b extmod/moduwebsocket: Refactor `websocket` to `uwebsocket`.
As mentioned in #4450, `websocket` was experimental with a single intended
user, `webrepl`. Therefore, we'll make this change without a weak
link `websocket` -> `uwebsocket`.

Paul m. p. P 454cca6016 py/objmodule: Implement PEP 562's __getattr__ for modules.
Configurable via MICROPY_MODULE_GETATTR, disabled by default.  Among other
things __getattr__ for modules can help to build lazy loading / code
unloading at runtime.

Damien George 04f7da78db py/objmodule: Remove TODO about checking store attr to a module.
The code implements correct behaviour, as tested by basics/module1.py.

Damien George 4cd853fbd2 py/objmodule: Make mp_obj_module_get_globals an inline function.
Because this function is simple it saves code size to have it inlined.
Being an auxiliary helper function (and only used in the py/ core) the
argument should always be an mp_obj_module_t*, so there's no need for the
assert (and having it would require including assert.h in obj.h).

Paul Sokolovsky 567bc2d6ce extmod/moducryptolib: Add ucryptolib module with crypto functions.
The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.

The naming of the module follows (u)hashlib pattern.

At the bare minimum, this module is expected to provide:

* AES128, ECB (i.e. "null") mode, encrypt only

Implementation in this commit is based on axTLS routines, and implements
following:

* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt

Damien George 6e7819ee2e py/objmodule: Factor common code for calling __init__ on builtin module. 2018-02-20 17:56:58 +11:00
Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
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.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George e9cb1f8077 py/objmodule: Move module init/deinit code into runtime functions.
They are one-line functions and having them inline in mp_init/mp_deinit
eliminates the overhead of a function call, and matches how other state
is initialised in mp_init.

Damien George 9de91914fb py: Move weak-link map to objmodule.c, and expose module maps as public. 2017-01-22 11:59:29 +11:00
Paul Sokolovsky d02f6a9956 extmod/modutimeq: Refactor into optimized class.
import utimeq, utime
    # Max queue size, the queue allocated statically on creation
    q = utimeq.utimeq(10)
    q.push(utime.ticks_ms(), data1, data2)
    res = [0, 0, 0]
    # Items in res are filled up with results
    q.pop(res)

Paul Sokolovsky 8f5bc3ffc0 stmhal/moduselect: Move to extmod/ for reuse by other ports. 2016-11-21 00:05:56 +03:00
Damien George 93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.

Paul Sokolovsky ddb9dba2f7 py/modio: Rename module name to "uio" for consistency with other modules. 2016-05-02 13:56:33 +03:00
Paul Sokolovsky 25d0f7d59d extmod/modwebrepl: Module to handle WebREPL protocol.
While just a websocket is enough for handling terminal part of WebREPL,
handling file transfer operations requires demultiplexing and acting
upon, which is encapsulated in _webrepl class provided by this module,
which wraps a websocket object.

Dave Hylands f925165942 unix: Move modmachine into unix directory
This leaves behind the common functionality in extmod/machine_mem.c
which can be used by all ports.

Paul Sokolovsky 1a1d11fa32 py/modsys: Implement sys.modules.
This for example will allow people to reload modules which didn't load
successfully (e.g. due to syntax error).

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

Paul Sokolovsky 0116218fa8 modmachine: Add new module to access hardware, starting with physical memory.
Refactored from "stm" module, provides mem8, mem16, mem32 objects with
array subscript syntax.

Damien George 044c473de2 py: Add %q format support to mp_[v]printf, and use it. 2015-04-16 14:30:16 +00:00
Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Damien George b1bbe966c4 py: Combine load_attr and store_attr type methods into one (attr).
This simplifies the API for objects and reduces code size (by around 400
bytes on Thumb2, and around 2k on x86).  Performance impact was measured
with Pystone score, but change was barely noticeable.

Paul Sokolovsky 0ef01d0a75 py: Implement core of OrderedDict type.
Given that there's already support for "fixed table" maps, which are
essentially ordered maps, the implementation of OrderedDict just extends
"fixed table" maps by adding an "is ordered" flag and add/remove
operations, and reuses 95% of objdict code, just making methods tolerant
to both dict and OrderedDict.

Some things are missing so far, like CPython-compatible repr and comparison.

OrderedDict is Disabled by default; enabled on unix and stmhal ports.

Damien George b4b10fd350 py: Put all global state together in state structures.
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.
2015-01-07 20:33:00 +00:00
Damien George 51dfcb4bb7 py: Move to guarded includes, everywhere in py/ core.
Addresses issue #1022.
2015-01-01 20:32:09 +00:00
Damien George 78d702c300 py: Allow builtins to be overridden.
This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
which, when enabled, allows to override all names within the builtins
module.  A builtins override dict is created the first time the user
assigns to a name in the builtins model, and then that dict is searched
first on subsequent lookups.  Note that this implementation doesn't
allow deleting of names.

This patch also does some refactoring of builtins code, creating the
modbuiltins.c file.

Addresses issue #959.
2014-12-09 16:19:48 +00:00
Paul Sokolovsky 346aacf27f unix: fast: Set initial module dict size big to have high pystone score.
For this, introduce MICROPY_MODULE_DICT_SIZE config setting.

Damien George 377b80b624 py: Print imported module's location (__file__) if available. 2014-09-08 10:45:23 +01:00
Damien George 04b9147e15 Add license header to (almost) all files.
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/.
2014-05-03 23:27:38 +01:00
Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.
2014-05-02 17:48:40 +03:00
Damien George 1d24ea5207 py: Finish implementation of all del opcodes.
At this point, all opcodes are now implemented!

Some del opcodes have been combined with store opcodes, with the value
to store being MP_OBJ_NULL.
2014-04-08 21:11:49 +01:00
Damien George 7efc5b3f34 py: Make globals and locals proper dictionary objects.
Finishes addressing issue #424.

In the end this was a very neat refactor that now makes things a lot
more consistent across the py code base.  It allowed some
simplifications in certain places, now that everything is a dict object.

Also converted builtins tables to dictionaries.  This will be useful
when we need to turn builtins into a proper module.
