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
Damien George	ffa98cb014	webassembly/proxy_js: Reuse JsProxy ref if object matches. ... This reduces memory use by reusing objects, and improves identity/equality relationships of JavaScript objects on the Python side. In 77bd8fe5b8 PyProxy's were reused when the same Python object was proxied across to JavaScript. This commit does the same thing but for JsProxy's going from JS to Python. If an existing JsProxy reference exists for the JS object about to be proxied across, then it's reused. This helps reduce the number of alive objects (memory use), and, more importantly, improves equality relationships of JavaScript objects on the Python side. Eg we now get, on the Python side: import js print(js.Object == js.Object) that prints True. Previously it was False. Note that this change does not make identity work with `is`, for example `js.Object is js.Object` is actually False. With more work that could be made True but for now we leave that as-is. The behaviour with this commit matches Pyodide semantics. Signed-off-by: Damien George <damien@micropython.org>	2025-07-31 11:40:50 +10:00

Angus Gratton	77c9eb7795	esp32: Add "Free RAM" optimisation config flags. ... This is necessary for ESP32-C2 Wi-Fi & BT to work reliably (and for TLS to work at all). On IDF 5.4.2 the free static RAM goes from 60KB to 100KB, and there will also be a reduction in lwIP & Wi-Fi memory use at runtime. The performance trade-off seems low for most use cases, although it will probably be significant for certain combinations of load (i.e. heavy TCP/IP, heavy BT throughput, and some peripheral driver functions). Added as a set of config flags because this is potentially useful on other SoCs where the goal is to maximise RAM available for MicroPython. This work was funded through GitHub Sponsors.

Damien George	79b2d4ff22	esp32/machine_uart: Improve sendbreak so it doesn't reconfig the UART. ... Currently, `UART.sendbreak()` on esp32 will reconfigure the UART to a slower baudrate and send out a null byte, to synthesise a break condition. That's not great because it changes the baudrate of the RX path as well, which could miss incoming bytes while sending the break.

Alessandro Gatti	b63e528076	examples/natmod/btree: Fix build on RV32 with Picolibc. ... This commit fixes building the "btree" example natmod on RV32 when Picolibc is being used and uses thread-local storage for storing the errno variable. The fix is surprisingly simple: Picolibc allows overriding the function that will provide a pointer to the "errno" variable, and the btree natmod integration code already has all of this machinery set up as part of its library integration. Redirecting Picolibc to the already existing pointer provider function via a compile-time definition is enough to let the module compile and pass QEMU tests. This workaround will work on any Picolibc versions (Arm, RV32, Xtensa, etc.) even if TLS support was not enabled to begin with, and will effectively do nothing if the toolchain used will rely on Newlib to provide standard C library functions. Given that the btree module now builds and passes the relevant natmod tests, said module is now part of the QEMU port's natmod testing procedure, and CI now will build the btree module for RV32 as part to its checks.

Damien George	0b698b8241	rp2/mpnetworkport: Deregister all sys timeouts when netif is removed. ...

These functions could be explicitly removed using `sys_untimeout()`, but `mdns_handle_tc_question()` is static so it's not possible to access it. Instead use the new `sys_untimeout_all_with_arg()` helper to deregister all timeout callbacks when a netif is removed. Fixes issue #17621.

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.
