2017-04-22py/objtype: mp_obj_new_super doesn't need to be public, so inline it.Damien George
Saves code size (20 bytes on bare-arm) and makes it a tiny bit more efficient.
2017-04-12py/objfloat: Add implementation of high-quality float hashing.Damien George
Disabled by default.
2017-04-12py: Optimise types for common case where type has a single parent type.Damien George
The common cases for inheritance are 0 or 1 parent types, for both built-in types (eg built-in exceptions) as well as user defined types. So it makes sense to optimise the case of 1 parent type by storing just the type and not a tuple of 1 value (that value being the single parent type). This patch makes such an optimisation. Even though there is a bit more code to handle the two cases (either a single type or a tuple with 2 or more values) it helps reduce overall code size because it eliminates the need to create a static tuple to hold single parents (eg for the built-in exceptions). It also helps reduce RAM usage for user defined types that only derive from a single parent. Changes in code size (in bytes) due to this patch: bare-arm: -16 minimal (x86): -176 unix (x86-64): -320 unix nanbox: -384 stmhal: -64 cc3200: -32 esp8266: -108
2017-04-12py/obj: Clean up and add comments describing mp_obj_type_t struct.Damien George
2017-04-04py: Add very simple but correct hashing for float and complex numbers.Damien George
Hashing of float and complex numbers that are exact (real) integers should return the same integer hash value as hashing the corresponding integer value. Eg hash(1), hash(1.0) and hash(1+0j) should all be the same (this is how Python is specified: if x==y then hash(x)==hash(y)). This patch implements the simplest way of doing float/complex hashing by just converting the value to int and returning that value.
2017-04-02py/obj.h: Make sequence grow more efficient and support overlapping.Damien George
The first memmove now copies less bytes in some cases (because len_adj <= slice_len), and the memcpy is replaced with memmove to support the possibility that dest and slice regions are overlapping.
2017-03-29py: Change mp_uint_t to size_t for mp_obj_str_get_data len arg.Damien George
2017-03-29py: Convert mp_uint_t to size_t for tuple/list accessors.Damien George
This patch changes mp_uint_t to size_t for the len argument of the following public facing C functions: mp_obj_tuple_get mp_obj_list_get mp_obj_get_array These functions take a pointer to the len argument (to be filled in by the function) and callers of these functions should update their code so the type of len is changed to size_t. For ports that don't use nan-boxing there should be no change in generate code because the size of the type remains the same (word sized), and in a lot of cases there won't even be a compiler warning if the type remains as mp_uint_t. The reason for this change is to standardise on the use of size_t for variables that count memory (or memory related) sizes/lengths. It helps builds that use nan-boxing.
2017-03-26py/obj: Change mp_uint_t to size_t for mp_obj_get_array_fixed_n len arg.Damien George
2017-03-23py: Define and use MP_OBJ_ITER_BUF_NSLOTS to get size of stack iter buf.Damien George
It improves readability of code and reduces the chance to make a mistake. This patch also fixes a bug with nan-boxing builds by rounding up the calculation of the new NSLOTS variable, giving the correct number of slots (being 4) even if mp_obj_t is larger than the native machine size.
2017-03-23py/sequence: Convert mp_uint_t to size_t where appropriate.Damien George
2017-03-23py: Use size_t as len argument and return type of mp_get_index.Damien George
These values are used to compute memory addresses and so size_t is the more appropriate type to use.
2017-02-24py: Fix varg helpers by adding vlist variant of mp_obj_new_exception_msgScott Shawcroft
2017-02-16py: Add iter_buf to getiter type method.Damien George
Allows to iterate over the following without allocating on the heap: - tuple - list - string, bytes - bytearray, array - dict (not dict.keys, dict.values, dict.items) - set, frozenset Allows to call the following without heap memory: - all, any, min, max, sum TODO: still need to allocate stack memory in bytecode for iter_buf.

2017-02-16py/objtuple: Convert mp_uint_t to size_t where appropriate.Damien George
2017-02-08py/map: Change mp_uint_t to size_t where appropriate.Damien George
The internal map/set functions now use size_t exclusively for computing addresses. size_t is enough to reach all of available memory when computing addresses so is the right type to use. In particular, for nanbox builds it saves quite a bit of code size and RAM compared to the original use of mp_uint_t (which is 64-bits on nanbox builds).
2017-01-10Merge tag 'v1.8.7'Scott Shawcroft
Support for Xtensa emitter and assembler, and upgraded F4 and F7 STM HAL This release adds support for the Xtensa architecture as a target for the native emitter, as well as Xtensa inline assembler. The int.from_bytes and int.to_bytes methods now require a second argument (the byte order) per CPython (only "little" is supported at this time). The "readall" method has been removed from all stream classes that used it; "read" with no arguments should be used instead. There is now support for importing packages from compiled .mpy files. Test coverage is increased to 96%. The generic I2C driver has improvements: configurable clock stretching timeout, "stop" argument added to readfrom/writeto methods, "nack" argument added to readinto, and write[to] now returns num of ACKs received. The framebuf module now handles 16-bit depth (generic colour format) and has hline, vline, rect, line methods. A new utimeq module is added for efficient queue ordering defined by modulo time (to be compatible with time.ticks_xxx functions). The pyboard.py script has been modified so that the target board is not reset between scripts or commands that are given on a single command line. For the stmhal port the STM Cube HAL has been upgraded: Cube F4 HAL to v1.13.1 (CMSIS 2.5.1, HAL v1.5.2) and Cube F7 HAL to v1.1.2. There is a more robust pyb.I2C implementation (DMA is now disabled by default, can be enabled via an option), and there is an implementation of machine.I2C with robust error handling and hardware acceleration on F4 MCUs. It is now recommended to use machine.I2C instead of pyb.I2C. The UART class is now more robust with better handling of errors/timeouts. There is also more accurate VBAT and VREFINT measurements for the ADC. New boards that are supported include: NUCLEO_F767ZI, STM32F769DISC and NUCLEO_L476RG. For the esp8266 port select/poll is now supported for sockets using the uselect module. There is support for native and viper emitters, as well as an inline assembler (with limited iRAM for storage of native functions, or the option to store code to flash). There is improved software I2C with a slight API change: scl/sda pins can be specified as positional only when "-1" is passed as the first argument to indicate the use of software I2C. It is recommended to use keyword arguments for scl/sda. There is very early support for over-the-air (OTA) updates using the yaota8266 project.

2016-12-21py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.Damien George
And also simplify it to remove the check for small int. This can be done because this function is only ever called if the argument is not a small int.
2016-11-21This introduces an alternative hardware API called nativeio structured ↵Scott Shawcroft
around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware. Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/ It differs from upstream's machine in the following ways: * Python API is identical across ports due to code structure. (Lives in shared-bindings) * Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC). * Documentation lives with code making it easy to ensure they match. * Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut). * All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware. * All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.
2016-10-21py: Specialise builtin funcs to use separate type for fixed arg count.Damien George
Builtin functions with a fixed number of arguments (0, 1, 2 or 3) are quite common. Before this patch the wrapper for such a function cost 3 machine words. After this patch it only takes 2, which can reduce the code size by quite a bit (and pays off even more, the more functions are added). It also makes function dispatch slightly more efficient in CPU usage, and furthermore reduces stack usage for these cases. On x86 and Thumb archs the dispatch functions are now tail-call optimised by the compiler. The bare-arm port has its code size increase by 76 bytes, but stmhal drops by 904 bytes. Stack usage by these builtin functions is decreased by 48 bytes on Thumb2 archs.
2016-10-21py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.Damien George
In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros.
2016-09-22all: Remove 'name' member from mp_obj_module_t struct.Damien George
One can instead lookup __name__ in the modules dict to get the value.
2016-08-15py/obj.h: For obj reprs A,B,C use void* explicitly for mp_obj_t typedef.Damien George
The machine_ptr_t type is long obsolete as the type of mp_obj_t is now defined by the object representation, ie by MICROPY_OBJ_REPR. So just use void* explicitly for the typedef of mp_obj_t. If a port wants to use something different then they should define a new object representation.
2016-06-18all: Rename mp_obj_type_t::stream_p to protocol.Paul Sokolovsky
It's now used for more than just stream protocol (e.g. pin protocol), so don't use false names.
2016-05-04py/obj: Add warning note about get_array return value and GC blocks.Damien George
2016-04-26py/obj.h: When constructing a small-int cast to mp_uint_t for bit-shift.Damien George
The C standard says that left-shifting a signed value (on the LHS of the operator) is undefined. So we cast to an unsigned integer before the shift. gcc does not issue a warning about this, but clang does.
2016-04-13py: add async/await/async for/async with syntaxpohmelie
They are sugar for marking function as generator, "yield from" and pep492 python "semantically equivalents" respectively. @dpgeorge was the original author of this patch, but @pohmelie made changes to implement `async for` and `async with`.
2016-04-05py: Move stream-related declarations from obj.h to stream.h.Paul Sokolovsky
2016-04-04py/obj.h: Add comment why mp_fun_kw_t takes non-const mp_map_t*.Paul Sokolovsky
mp_fun_kw_t takes mp_map_t* (and not const mp_map_t*) to ease passing this arg to mp_map_lookup(), which may modify its arg, depending on flags.
2016-03-15py: For mp_buffer_info_t, change len type from mp_uint_t to size_t.Damien George
2016-02-14py/obj.h: If not float support is enabled, define mp_obj_is_float(o) to false.Paul Sokolovsky
We have so many configuration options, that finally having shortcuts like this is helpful and cuts on number of ifdef's.
2016-01-27py/inlineasm: Add ability to specify return type of asm_thumb funcs.Damien George
Supported return types are: object, bool, int, uint. For example: @micropython.asm_thumb def foo(r0, r1) -> uint: add(r0, r0, r1)
2016-01-11py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George
The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.
2016-01-11py: Change type signature of builtin funs that take variable or kw args.Damien George
With this patch the n_args parameter is changed type from mp_uint_t to size_t.
2016-01-11py: Change type of .make_new and .call args: mp_uint_t becomes size_t.Damien George
This patch changes the type signature of .make_new and .call object method slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more efficient when mp_uint_t is larger than a machine word. Doesn't affect ports when size_t and mp_uint_t have the same size.
2016-01-10py: Remove long-obsolete mp_method_t typedef.Damien George
2016-01-08py/obj: For OBJ_REPR_D, use uint32_t cast when extracting qstr value.Damien George
2016-01-03py: Change struct and macro for builtin fun so they can be type checked.Damien George
2016-01-02py: Change exception traceback data to use size_t instead of mp_uint_t.Damien George
The traceback array stores qstrs and line numbers. qstrs are typed as size_t, and line numbers should safely fit in size_t as well.
2015-12-20py/objstr: Make sure that b"%s" % b"foo" uses undecorated bytes value.Paul Sokolovsky
I.e. the expected result for above is b"foo", whereas previously we got b"b'foo'".
