Andrew Leech	295df7c0b4	github/workflows: Drop VS2017, use preinstalled v142 toolset for VS2019. ... The VS 2017 and VS 2019 MSVC CI jobs have been failing intermittently for months due to Chocolatey/Microsoft installer infrastructure issues when downloading old Visual Studio build tools onto windows-latest runners. These are not code failures - the build tools installation itself is unreliable (CDN timeouts, corrupt downloads, installer self-update loops). This removes VS 2017 from the matrix entirely and switches VS 2019 to use the v142 toolset that's already pre-installed on windows-2022 runners as a component of VS 2022. The PlatformToolset is now passed explicitly to MSBuild for both VS 2019 (v142) and VS 2022 (v143), and the Chocolatey installation step is removed. VS 2017 reached end-of-life in 2022, and the v141 toolset is no longer reliably installable on GitHub-hosted runners (actions/runner-images#9701, actions/runner-images#12764). The windows-2019 runner image was removed in June 2025. Docker containers are not supported on Windows runners, and the repo's 10GB Actions cache is already full, so caching the installation isn't feasible either. MSVC v143 is binary-compatible back to v141, so the testing value of v141 was marginal. The net effect is 16 MSVC jobs (down from 24) with zero installation steps and hopefully no more flaky failures.

Alessandro Gatti	2f16bf430a	esp32/network_wlan: Look up IP addresses for the stations list. ... This commit extends the output of `WLAN.status('stations')` to also include the IP address of WiFi stations connected to the device if in AP mode. IP address lookup is currently not available on targets that use hosted WiFi (eg. ESP32P4), as the hosted API does not yet support performing the MAC->IP lookup on the WiFi MCU end. The ESP32 port is brought up to parity with most ports in this regard (primarily with the ESP8266). This functionality depends on the DHCP server provided by ESP-IDF, which is automatically run on the WiFi interface if the device is put in AP mode. Currently the ESP32 port cannot run with said DHCP server disabled, so if a device does not request a static IP it may either have the wrong IP address returned (since the DHCP server assigned an address which is then discarded by the client), or it won't have any (ie. "0.0.0.0"). In the latter case `None` will be returned as the station's address instead. This implements #9203. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2026-04-08 22:04:55 +10:00

Alessandro Gatti	024178455d	unix/modsocket: Add "sendall" method to socket class. ... This commit adds an implementation for "socket.sendall" to the Unix port. Right now the implementation is a wrapper over a single "socket.send" call, since it wasn't possible to let "socket.send" perform a partial transfer. With no partial transfers it is not possible to have a testable implementation following the expected behaviour, so a single send operation is done and OSErr(EINTR) is raised if a partial transfer occurs. The discussion for the issue linked to this PR contains more information about the efforts made to let partial transfers happen. This fixes #16803.

This commit extends the parser's behaviour to also recognise constant integer assignments even when the assignment itself has a type annotation.

Damien George	d41b8dc52e	py/emitglue: Fix macro logic that selects cache flushing code. ... This fixes a regression made by 9e9da6cb0d. There are two issues here: 1. `MPY_FEATURE_ARCH` and `MP_NATIVE_ARCH_xxx` are not visible in this file because `py/persistentcode.h` is not included. 2. Even if they were visible the macro logic will not work because `MP_NATIVE_ARCH_xxx` are enum values and cannot be used in #if logic. What this means is that the first #if is always true, so there is no cache flushing on ARM (non-Thumb) or RISC-V targets. This breaks native code on, eg, ESP32-P4. The fix here aims to simplify the logic by using built-in compiler defines to select the target: - On an ARM Thumb target with `__ICACHE_PRESENT` enabled, it will flush the cache. - On an ARM (non-Thumb) target, it will prefer `__builtin___clear_cache()` if possible, otherwise it will use inline assembler. - On a RISC-V target, it will use `MP_HAL_CLEAN_DCACHE()` if that macro is defined (that's only on ESP32-P4 at the moment). The logic should be the same as before, except for the cases where an emitter is enabled on a mismatching architecture. For example, if `MICROPY_EMIT_THUMB` and/or `MICROPY_EMIT_INLINE_THUMB` were enabled on a non-Thumb target, previously that will try to generate code to flush caches (which doesn't really make sense), but now it will not. This actually happened for `mpy-cross` which does enable all the emitters, and prior to this fix would follow the Thumb path, but not generate any code because `__ICACHE_PRESENT` is disabled (at least when building `mpy-cross` on x86).

Damien George	74e945752b	py/modweakref: Implement weakref module with ref and finalize classes. ... This adds support for the standard `weakref` module, to make weak references to Python objects and have callbacks for when an object is reclaimed by the GC. This feature was requested by PyScript, to allow control over the lifetime of external proxy objects (distinct from JS<->Python proxies). Addresses issue #646 (that's nearly a 12 year old issue!). Functionality added here: - `weakref.ref(object [, callback])` create a simple weak reference with optional callback to be called when the object is reclaimed by the GC - `weakref.finalize(object, callback, /, *args, **kwargs)` create a finalize object that holds a weak reference to an object and allows more convenient callback usage and state change The new module is enabled at the "everything" level. The implementation aims to be as efficient as possible, by adding another bit-per-block to the garbage collector, the WTB (weak table). Similar to the finalizer bit (FTB), if a GC block has its corresponding WTB bit set then a weak reference to that block is held. The details of that weak reference are stored in a global map, `mp_weakref_map`, which maps weak reference to ref/finalize objects, allowing the callbacks to be efficiently found when the object is reclaimed. With this feature enabled the overhead is: - 1/128th of the available memory is used for the new WTB table (eg a 128k heap now needs an extra 1k for the WTB). - Code size is increased. - At garbage collection time, there is a small overhead to check if the collected objects had weak references. This check is the same as the existing FTB finaliser scan, so shouldn't add much overhead. If there are weak reference objects alive (ref/finalize objects) then additional time is taken to call the callbacks and do some accounting to clean up the used weak reference.
