Damien George	09d070aa55	tests/extmod_hardware: Add tests for machine.UART.IRQ_RX/RXIDLE/BREAK. ... These all require hardware connections, so live in a different directory. Except for the IRQ_BREAK test of ESP32 devices a single UART with loopback is sufficient. General: SAMD21: Due to the limited flash size only SAMD21 devices with external flash support uart.irq(). IRQ_BREAK: ESP32 needs different UART devices for creating and sensing a break. Lacking a second UART the test is skipped for ESP32S2 and ESP32C3. RP2 does not pass the test reliable at 115200 baud, reason to be found. Thus the upper limit is set to 57600 Baud. Coverage: esp32 pass when different UART devices are used. rp2 pass up to 57600 baud IRQ_RX: SAMD21: Being a slow device it needs data to be sent byte-by-byte at 9600 baud, since the IRQ callback is scheduled delayed and then the flags do not match any more. The data matches since it is queued in the FIFO resp. ringbuffer. CC3200: The test cannot be performed since no calls are accepted in the IRQ handler like u.read(). Skipped. Coverage: cc3200 fail due to major differences in the implementation. esp32 pass nrf pass renesas-ra pass samd pass see the notes. stm32 pass IRQ_RXIDLE: STM32: With PyBoard the IRQ is called several times, but only once with the flag IRQ_RXIDLE set. Coverage: esp32 pass mimxrt pass renesas-ra pass rp2 pass samd pass for both SAMD21 and SAMD51 stm32 fail. see notes.

Damien George	d9a0fdda9a	qemu-arm: Rework to provide a REPL and run tests via a pty serial port. ... Currently, the qemu-arm (and qemu-riscv) port has two build modes: - a simple test that executes a Python string; and - a full test that uses tinytest to embed all tests within the firmware, then executes that and captures the output. This is very different to all the other ports. A difficulty with using tinytest is that with the large number of tests the firmware overflows its virtual flash size. It's also hard to run tests via .mpy files and with the native emitter. Being different to the other ports also means an extra burden on maintenance. This commit reworks the qemu-arm port so that it has a single build target that creates a standard firmware which has a REPL. When run under qemu-system-arm, the REPL acts like any other bare-metal port, complete with soft reset (use machine.reset() to turn it off and exit qemu-system-arm). This approach gives many benefits: - allows playing with a REPL without hardware; - allows running the test suite as it would on a bare-metal board, by making qemu-system-arm redirect the UART serial of the virtual device to a /dev/pts/xx file, and then running run-tests.py against that serial device; - skipping tests is now done via the logic in `run-tests.py` and no longer needs multiple places to define which tests to skip (`tools/tinytest-codegen.py`, `ports/qemu-arm/tests_profile.txt` and also `tests/run-tests.py`); - allows testing/using mpremote with the qemu-arm port. Eventually the qemu-riscv port would have a similar change. Prior to this commit the test results were: 743 tests ok. (121 skipped) With this commit the test results are: 753 tests performed (22673 individual testcases) 753 tests passed 138 tests skipped More tests are skipped because more are included in the run. But overall more tests pass. Signed-off-by: Damien George <damien@micropython.org>	2024-08-28 11:52:08 +10:00

Angus Gratton	337742f6c7	esp32/mpthreadport: Fix uneven GIL allocation between Python threads. ... Explicitly yield each time a thread mutex is unlocked. Key to understanding this bug is that Python threads run at equal RTOS priority, and although ESP-IDF FreeRTOS (and I think vanilla FreeRTOS) scheduler will round-robin equal priority tasks in the ready state it does not make a similar guarantee for tasks moving between ready and waiting. The pathological case of this bug is when one Python thread task is busy (i.e. never blocks) it will hog the CPU more than expected, sometimes for an unbounded amount of time. This happens even though it periodically unlocks the GIL to allow another task to run. Assume T1 is busy and T2 is blocked waiting for the GIL. T1 is executing and hits a condition to yield execution: 1. T1 calls MP_THREAD_GIL_EXIT 2. FreeRTOS sees T2 is waiting for the GIL and moves it to the Ready list (but does not preempt, as T2 is same priority, so T1 keeps running). 3. T1 immediately calls MP_THREAD_GIL_ENTER and re-takes the GIL. 4. Pre-emptive context switch happens, T2 wakes up, sees GIL is not available, and goes on the waiting list for the GIL again. To break this cycle step 4 must happen before step 3, but this may be a very narrow window of time so it may not happen regularly - and quantisation of the timing of the tick interrupt to trigger a context switch may mean it never happens. Yielding at the end of step 2 maximises the chance for another task to run. Adds a test that fails on esp32 before this fix and passes afterwards. Fixes issue #15423.

Damien George	77bd8fe5b8	webassembly: Reuse PyProxy objects when they are the same Python object. ... This commit makes it so that PyProxy objects are reused (on the JavaScript side) when they correspond to an existing Python object that is the same object. For example, proxying the same Python function to JavaScript, the same PyProxy instance is now used. This means that if `foo` is a Python function then accessing it on the JavaScript side such as `api.globals().get("foo")` has the property that: api.globals().get("foo") === api.globals().get("foo") Prior to this commit the above was not true because new PyProxy instances were created each time `foo` was accessed.

Jim Mussared	557d31ed2c	py/objint: Try to convert big-int back to small-int after binary op. ... Before this change, long/mpz ints propagated into all future calculations, even if their value could fit in a small-int object. With this change, the result of a big-int binary op will now be converted to a small-int object if the value fits in a small-int. For example, a relatively common operation like `x = a * b // c` where a,b,c all small ints would always result in a long/mpz int, even if it didn't need to, and then this would impact all future calculations with x. This adds +24 bytes on PYBV11 but avoids heap allocations and potential surprises (e.g. `big-big` is now a small `0`, and can safely be accessed with MP_OBJ_SMALL_INT_VALUE). Performance tests are unchanged on PYBV10, except for `bm_pidigits.py` which makes heavy use of big-ints and gains about 8% in speed. Unix coverage tests have been updated to cover mpz code that is now unreachable by normal Python code (removing the unreachable code would lead to some surprising gaps in the internal C functions and the functionality may be needed in the future, so it is kept because it has minimal overhead).

Damien George	95c19e05ff	webassembly/objjsproxy: Lookup attributes without testing they exist. ... In JavaScript when accessing an attribute such as `obj.attr` a value of `undefined` is returned if the attribute does not exist. This is unlike Python semantics where an `AttributeError` is raised. Furthermore, in some cases in JavaScript (eg a Proxy instance) `attr in obj` can return false yet `obj.attr` is still valid and returns something other than `undefined`. So the source of truth for whether a JavaScript attribute exists is to just right away attempt `obj.attr`. To more closely match these JavaScript semantics when proxying a JavaScript object through to Python, change the attribute lookup logic on a `JsProxy` so that it immediately attempts `obj.attr` instead of first testing if the attribute exists via `attr in obj`. This allows JavaScript objects which dynamically create attributes to work correctly on the Python side, with both `obj.attr` and `obj["attr"]`. Note that `obj["attr"]` already works in all cases because it immediately does the subscript access without first testing if the attribute exists. As a benefit, this new behaviour matches the Pyodide behaviour. Signed-off-by: Damien George <damien@micropython.org>	2024-06-28 11:40:24 +10:00
Angus Gratton	068d9bf2cf	rp2: Fix USB PLL glitch during wake from light sleep. ... Follow-up to a84c7a0ed9, this commit works most of the time but has an intermittent bug where USB doesn't resume as expected after waking from light sleep. Turns out waking calls clocks_init() which will re-initialise the USB PLL. Most of the time this is OK but occasionally it seems like the clock glitches the USB peripheral and it stops working until the next hard reset. Adds a machine.lightsleep() test that consistently hangs in the first two dozen iterations on rp2 without this fix. Passed over 100 times in a row with this fix. The test is currently rp2-only as it seems similar lightsleep USB issues exist on other ports (both pyboard and ESP32-S3 native USB don't send any data to the host after waking, until they receive something from the host first.)

Angus Gratton	cfa55b4ca1	rp2: Fix recursive atomic sections when core1 is active. ... mp_thread_begin_atomic_section() is expected to be recursive (i.e. for nested machine.disable_irq() calls, or if Python code calls disable_irq() and then the Python runtime calls mp_handle_pending() which also enters an atomic section to check the scheduler state). On rp2 when not using core1 the atomic sections are recursive. However when core1 was active (i.e. _thread) then there was a bug that caused the core to live-lock if an atomic section recursed. Adds a test case specifically for mutual exclusion and recursive atomic sections when using two threads. Without this fix the test immediately hangs on rp2.

Angus Gratton	908ab1ceca	py/objint: Fix int.to_bytes() buffer size checks. ... Fixes and improvements to `int.to_bytes()` are: - No longer overflows if byte size is 0 (closes #13041). - Raises OverflowError in any case where number won't fit into byte length (now matches CPython, previously MicroPython would return a truncated bytes object). - Document that `micropython int.to_bytes()` doesn't implement the optional signed kwarg, but will behave as if `signed=True` when the integer is negative (this is the current behaviour). Add tests for this also. Requires changes for small ints, MPZ large ints, and "long long" large ints. Adds a new set of unit tests for ints between 32 and 64 bits to increase coverage of "long long" large ints, which are otherwise untested.

The latter is fixed in this commit. A test is added for these timeout cases. Signed-off-by: Damien George <damien@micropython.org>	2024-06-08 09:02:01 +10:00
Damien George	3c8089d1b1	py/lexer: Support raw f-strings. ... Support for raw str/bytes already exists, and extending that to raw f-strings is easy. It also reduces code size because it eliminates an error message. Signed-off-by: Damien George <damien@micropython.org>	2024-06-06 17:34:28 +10:00
Damien George	a066f2308f	py/lexer: Support concatenation of adjacent f-strings. ... This is quite a simple and small change to support concatenation of adjacent f-strings, and improve compatibility with CPython. Signed-off-by: Damien George <damien@micropython.org>	2024-06-06 14:58:46 +10:00
