Damien George	b5fcb33eaa	py/mpconfig: Enable CRYPTOLIB, HASHLIB_MD5, HASHLIB_SHA1 if SSL enabled. ... This commit unifies the configuration of MICROPY_PY_CRYPTOLIB, MICROPY_PY_HASHLIB_MD5 and MICROPY_PY_HASHLIB_SHA1, so they are enabled by default if MICROPY_PY_SSL is enabled. This matches the existing configuration of most of the ports. With this change, all ports remain the same except: - reneses-ra now enables MICROPY_PY_CRYPTOLIB, MICROPY_PY_HASHLIB_MD5 and MICROPY_PY_HASHLIB_SHA1. - rp2 now enables MICROPY_PY_HASHLIB_MD5.

Yoctopuce dev	69ead7d98e	py/parse: Add support for math module constants and float folding. ... Add a new MICROPY_COMP_CONST_FLOAT feature, enabled by in mpy-cross and when compiling with MICROPY_CONFIG_ROM_LEVEL_CORE_FEATURES. The new feature leverages the code of MICROPY_COMP_CONST_FOLDING to support folding of floating point constants. If MICROPY_COMP_MODULE_CONST is defined as well, math module constants are made available at compile time. For example: _DEG_TO_GRADIANT = const(math.pi / 180) _INVALID_VALUE = const(math.nan) A few corner cases had to be handled: - The float const folding code should not fold expressions resulting into complex results, as the mpy parser for complex immediates has limitations. - The constant generation code must distinguish between -0.0 and 0.0, which are different even if C consider them as ==. This change removes previous limitations on the use of `const()` expressions that would result in floating point number, so the test cases of micropython/const_error have to be updated. Additional test cases have been added to cover the new repr() code (from a previous commit). A few other simple test cases have been added to handle the use of floats in `const()` expressions, but the float folding code itself is also tested when running general float test cases, as float expressions often get resolved at compile-time (with this change).

Yoctopuce dev	dbbaa959c8	py/formatfloat: Improve accuracy of float formatting code. ... Following discussions in PR #16666, this commit updates the float formatting code to improve the `repr` reversibility, i.e. the percentage of valid floating point numbers that do parse back to the same number when formatted by `repr` (in CPython it's 100%). This new code offers a choice of 3 float conversion methods, depending on the desired tradeoff between code size and conversion precision: - BASIC method is the smallest code footprint - APPROX method uses an iterative method to approximate the exact representation, which is a bit slower but but does not have a big impact on code size. It provides `repr` reversibility on >99.8% of the cases in double precision, and on >98.5% in single precision (except with REPR_C, where reversibility is 100% as the last two bits are not taken into account). - EXACT method uses higher-precision floats during conversion, which provides perfect results but has a higher impact on code size. It is faster than APPROX method, and faster than the CPython equivalent implementation. It is however not available on all compilers when using FLOAT_IMPL_DOUBLE. Here is the table comparing the impact of the three conversion methods on code footprint on PYBV10 (using single-precision floats) and reversibility rate for both single-precision and double-precision floats. The table includes current situation as a baseline for the comparison: PYBV10 REPR_C FLOAT DOUBLE current = 364688 12.9% 27.6% 37.9% basic = 364812 85.6% 60.5% 85.7% approx = 365080 100.0% 98.5% 99.8% exact = 366408 100.0% 100.0% 100.0% Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>	2025-08-01 00:47:33 +10:00

Yoctopuce dev	df05caea6c	shared/timeutils: Standardize supported date range on all platforms. ... This is code makes sure that time functions work properly on a reasonable date range, on all platforms, regardless of the epoch. The suggested minimum range is 1970 to 2099. In order to reduce code footprint, code to support far away dates is only enabled specified by the port. New types are defined to identify timestamps. The implementation with the smallest code footprint is when support timerange is limited to 1970-2099 and Epoch is 1970. This makes it possible to use 32 bit unsigned integers for all timestamps. On ARM4F, adding support for dates up to year 3000 adds 460 bytes of code. Supporting dates back to 1600 adds another 44 bytes of code.

Alessandro Gatti	2ab06b61b3	py/emitnative: Let emitters know the compiled entity's name. ... This commit introduces an optional feature to provide to native emitters the fully qualified name of the entity they are compiling. This is achieved by altering the generic ASM API to provide a third argument to the entry function, containing the name of the entity being compiled. Currently only the debug emitter uses this feature, as it is not really useful for other emitters for the time being; in fact the macros in question just strip the name away.

Yoctopuce dev	66c0148022	py/runtime: Add support for using __all__ in star import. ... When the symbol `__all__` is defined in a module, `mp_import_all()` should import all listed symbols into the global environment, rather than relying on the underscore-is-private default. This is the standard in CPython. Each item is loaded in the same way as if it would be an explicit import statement, and will invoke the module's `__getattr__` function if needed. This provides a straightforward solution for fixing star import of modules using a dynamic loader, such as `extmod/asyncio` (see issue #7266). This improvement has been enabled at BASIC_FEATURES level, to avoid impacting devices with limited ressources, for which star import is of little use anyway. Additionally, detailled reporting of errors during `__all__` import has been implemented to match CPython, but this is only enabled when ERROR_REPORTING is set to MICROPY_ERROR_REPORTING_DETAILED.

Alessandro Gatti	1006ed69f0	py/emitinlinextensa: Add the rest of LX3 opcodes to the assembler. ... This commit expands the Xtensa inline assembler to support most if not all opcodes available on the ESP8266 and LX3 Xtensa cores. This is meant as a stepping stone to add inline assembler support for the ESP32 and its LX6 core, along to windowed-specific opcodes and additional opcodes that are present only on the LX7 core (ESP32-S3 and later). New opcodes being added are covered by tests, and the provided tests were expanded to also include opcodes available in the existing implementation. Given that the ESP8266 space requirements are tighter than ESP32's, certain opcodes that won't be commonly used have been put behind a define to save some space in the general use case.

To maintain compaitiblity with existing code NORETURN is aliased to MP_NORETURN, but it is also deprecated for MicroPython v2.

This level is used when MICROPY_PY_BUILTINS_COMPILE is enabled. - MICROPY_PY_BUILTINS_CODE_BASIC: simple code object that holds a reference to the proto-function and its constants. - MICROPY_PY_BUILTINS_CODE_FULL: almost complete implementation of the code object.

This allows naturally getting the memory-mapped address of the file using: - memoryview(file) - uctypes.addressof(file) Furthermore, if these files are .mpy files then their content can be referenced in-place when importing.

J. Neuschäfer	7b050b366b	py/nlrthumb: Make non-Thumb2 long-jump workaround opt-in. ... Although the original motivation given for the workaround[1] is correct, nlr.o and nlrthumb.o are linked with a small enough distance that the problem does not occur, and the workaround isn't necessary. The distance between the b instruction and its target (nlr_push_tail) is just 64 bytes[2], well within the ±2046 byte range addressable by an unconditional branch instruction in Thumb mode. The workaround induces a relocation in the text section (textrel), which isn't supported everywhere, notably not on musl-libc[3], where it causes a crash on start-up. With the workaround removed, micropython works on an ARMv5T Linux system built with musl-libc. This commit changes nlrthumb.c to use a direct jump by default, but leaves the long jump workaround as an option for those cases where it's actually needed.

When enabled, this means that scope such as module-level functions and REPL statements can yield. The outer C code must then handle this yielded generator.

Matthias Urlichs	e520fa2e0f	py/binary: Support half-float 'e' format in struct pack/unpack. ... This commit implements the 'e' half-float format: 10-bit mantissa, 5-bit exponent. It uses native _Float16 if supported by the compiler, otherwise uses custom bitshifting encoding/decoding routines.

Dash Peters	7dff38fdc1	py/objdeque: Expand implementation to be doubly-ended and support iter. ... Add `pop()`, `appendleft()`, and `extend()` methods, support iteration and indexing, and initializing from an existing sequence. Iteration and indexing (subscription) have independent configuration flags to enable them. They are enabled by default at the same level that collections.deque is enabled (the extra features level). Also add tests for checking new behavior. Signed-off-by: Damien George <damien@micropython.org>	2024-03-18 14:10:14 +11:00
Damien George	bfc3dde2c9	extmod/modmachine: Add MICROPY_PY_MACHINE_RESET configuration option. ... Disabled by default, but enabled on all boards that previously had `MICROPY_PY_MACHINE_BARE_METAL_FUNCS` enabled. Signed-off-by: Damien George <damien@micropython.org>	2024-03-15 12:04:37 +11:00
