Angus Gratton	3dd8073c29	tools/mpremote: Workaround ESP DTR/RTS reset quirk at disconnect time. ... The problem with ESP board spurious reset happens at disconnect time on Windows (clearing DTR before RTS triggers a reset). Previous workarounds tried to detect possible ESP boards and apply the correct DTR and RTS settings when opening the port. Instead, we can manually clear RTS before closing the port and thereby avoid the reset issue. Opening the port can keep the default behaviour (RTS & DTR both set). close() is called from a finally block in the mpremote main module (via do_disconnect()) - so this should always happen provided the Python process isn't terminated by the OS. One additional workaround is needed to prevent a spurious reset first time a Silicon Labs CP210x-based ESP board is opened by mpremote after enumeration.

Damien George	a563592b11	webassembly/asyncio: Fix ThenableEvent to handle rejected thenables. ... Prior to this fix, if a JavaScript thenable/Promise that was part of an asyncio chain was rejected it would be ignored because the Python-side `ThenableEvent` did not register a handler for the rejection. That's fixed by this commit, and a corresponding test added. Signed-off-by: Damien George <damien@micropython.org>	2025-09-30 17:39:15 +10:00
Damien George	094000d418	webassembly/objjsproxy: Fix logic that determines if asyncio is active. ... `cur_task` can never be `None` in the webassembly port, so test it for the top-level task to see if an asyncio Task is active or not. This fixes a bug where await'ing on a JavaScript awaitable that ends up raising an error would not be caught on the Python side. The fix here makes sure it is caught by Python, as tested by the new test. Signed-off-by: Damien George <damien@micropython.org>	2025-09-30 17:39:15 +10:00
Damien George	68ca22bbc8	tests/ports/webassembly: Expand test for registerJsModule. ... This tests `from mod import foo` where `mod` is a module registered using the webassembly API `registerJsModule(mod)`, and where `foo` is a JavaScript function. Prior to the parent commit, this would fail. Signed-off-by: Damien George <damien@micropython.org>	2025-09-30 11:04:05 +10:00
Damien George	beb4c3188f	py/runtime: Support importing a method from an instance. ... This change follows CPython behaviour, allowing use of: from instance import method to import a bound method from a class instance, eg registered via setting `sys.modules["instance"] = instance`. Admittedly this is probably a very rarely used pattern in Python, but it resolves a long standing comment about whether or not this is actually possible (it turns out it is possible!). A test is added to show how it works. The main reason for this change is to fix a problem with imports in the webassembly port: prior to this fix, it was not possible to do `from js_module import function`, where `js_module` is a JavaScript object registered to be visible to Python through the webassembly API function `registerJsModule(js_module)`. But now with this fix that is possible. Signed-off-by: Damien George <damien@micropython.org>	2025-09-30 11:04:05 +10:00

Jeff Epler	7e5c55dc2f	py/mkrules.mk: Add %.sz rule to print size of an object file. ... It's frequently the case that a developer will want to compare the object code size of various alternatives.

Because it is a normal Makefile target that depends on an object file, it rebuilds the object file if needed. Signed-off-by: Jeff Epler <jepler@unpythonic.net>	2025-09-26 14:38:05 +10:00

Damien George	a319ddefa6	webassembly: Improve identity and fix bug with lost JsProxy refs. ... Commit ffa98cb014 improved equality for `JsProxy` objects so that, eg, `js.Object == js.Object` is true. As mentioned in #17758, a further optimisation is to make identity work in that case, eg `js.Object is js.Object` should be true (on the Python side). This commit implements that, by keeping track of all `JsProxy` Python objects and reusing them where possible: where the underlying JS ref is equal, ie they point to the same JS object. That reduces memory churn and gives better identity behaviour of JS objects proxied over to Python. As part of this, a bug is fixed where JS objects can be freed while there's still a `JsProxy` referring to that JS object. A test is added for that exact scenario, and the test now passes.

Damien George	9eddbb32f3	webassembly: Do GC in return path rather than entry path. ... Doing GC calls in the entry path (when JavaScript calls into MicroPython at the top/outer level) can lead to freeing of objects which are still in use. This is because the (JavaScript) objects are referenced in the input arguments to the C functions and they are not yet converted to full proxy objects and not yet tracked properly by the live-object tracker.

Damien George	03b4c60fc1	nrf/modules/machine/spi: Print SPI baudrate, polarity and phase. ... On most ports, printing an instance of machine.SPI gives something like: >>> machine.SPI(1) SPI(1, baudrate=328125, polarity=0, phase=0, bits=8) This commit makes the nrf port do the same. The reason for this change is: - make nrf consistent with other ports - allow the `tests/extmod/machine_spi_rate.py` to run on the nrf port (this tests parses the output of str(spi) to get the actual baudrate) Signed-off-by: Damien George <damien@micropython.org>	2025-09-26 13:44:43 +10:00

This commit refactors some common code in the core stream implementation, to reduce code size while retaining the same functionality.

Chris Webb	81985d20c9	shared/runtime/mpirq: Check separate hard IRQ stack correctly. ... On the zephyr port, hard IRQ handlers run with a separate stack on a different thread, so each call to mp_irq_dispatch() and mp_irq_handler() has to be wrapped with adjustments to the stack-limit checker. Move these adjustments into the shared mp_irq_dispatch(), introducing MICROPY_STACK_SIZE_HARD_IRQ which a port can define to non-zero if it uses a separate stack for hard IRQ handlers. We only need wrap the hard dispatch case. This should reduce binary size on zephyr without affecting other ports. Signed-off-by: Chris Webb <chris@arachsys.com>	2025-09-25 23:59:24 +10:00

Chris Webb	ec6cdf3718	tests: Test hardware timers as well as software timers. ... On platforms where hardware timers are available, test these in each combination of hard/soft and one-shot/periodic in the same way as for software timers.

For now, esp8266 is the only platform that supports hardware timers and both hard and soft callbacks. Signed-off-by: Chris Webb <chris@arachsys.com>	2025-09-25 23:59:24 +10:00
Chris Webb	ccc954256f	tests: Generalise rp2 timer test into a cross-port test. ... Now all ports with machine.Timer except nrf support both hard and soft callbacks, generalise tests/ports/rp2_machine_timer.py into tests/extmod/machine_timer.py. There is an existing machine_soft_timer.py which varies period= and covers the nrf port but skips esp32/esp8266 because they don't support software timers. In our new test, we try varying freq= instead of period=, and cover esp32/esp8266 (with a fixed choice of hardware timer) but skip nrf because it doesn't support hard= or freq=. Add a check that the heap is locked (so allocation fails) in hard callbacks and it is unlocked (so allocation succeeds) in soft callbacks, to ensure we're getting the right kind of callback, not falling back to the default.

Chris Webb	64fd2f5f36	esp32/machine_timer: Warn that hard timers are not implemented. ... machine.Timer() has inconsistent behaviour between ports: some run callbacks in hard IRQ context whereas others schedule them like soft IRQs. Most ports now support a hard= argument to the machine.Timer constructor or initialiser to explicitly choose between these behaviours. However, esp32 does not support hardware interrupts because they are not delivered to the main thread, so the interrupt handler would need to acquire the GIL.

Angus Gratton	046013a1ff	github/workflows: Run esp32&zephyr daily to keep mstr branch caches hot. ... Currently it seems if master branch doesn't build for 1-2 days then the cached ESP-IDF install (1.6GB) and Zephyr workspace (3.1GB) caches expire. Then each PR branch has to create its own redundant cache instead of falling back to the default branch cache, which is expensive and quickly blows our 10GB cache limit. Currently this is mitigated (and possibly happens more frequently) due to GitHub's relatively soft enforcement of the limit (at time of writing we're using 33GB of 10GB), but apparently they're going to start enforcing it more aggressively in October.
