Damien George	fa42487e45	extmod/moddeflate: Keep DeflateIO state consistent on window alloc fail. ... Allocation of a large compression window may fail, and in that case keep the `DeflateIO` state consistent so its other methods (such as `close()`) still work. Consistency is kept by only updating the `self->write` member if the window allocation succeeds. Thanks to @jimmo for finding the bug.

Damien George	f5b4545761	py/modsys: Add sys.implementation._build entry. ... For a given MicroPython firmware/executable it can be sometimes important to know how it was built, which variant/board configuration it came from. This commit adds a new field `sys.implementation._build` that can help identify the configuration that MicroPython was built with. For now it's either: * <VARIANT> for unix, webassembly and windows ports * <BOARD>-<VARIANT> for microcontroller ports (the variant is optional) In the future additional elements may be added to this string, separated by a hyphen.

Glenn Moloney	eb45d97898	py/objstr: Support tuples and start/end args in startswith and endswith. ... This change allows tuples to be passed as the prefix/suffix argument to the `str.startswith()` and `str.endswith()` methods. The methods will return `True` if the string starts/ends with any of the prefixes/suffixes in the tuple. Also adds full support for the `start` and `end` arguments to both methods for compatibility with CPython. Tests have been updated for the new behaviour.

Yoctopuce dev	5fdd249c55	py/parsenum: Reduce code footprint of mp_parse_num_float. ... The mantissa parsing code uses a floating point variable to accumulate digits. Using an `mp_float_uint_t` variable instead and casting to `mp_float_t` at the very end reduces code size. In some cases, it also improves the rounding behaviour as extra digits are taken into account by the int-to-float conversion code. An extra test case handles the special case where mantissa overflow occurs while processing deferred trailing zeros. Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>	2025-02-28 13:35:12 +11:00
Damien George	14ba32bb20	extmod/vfs_rom: Add bounds checking for all filesystem accesses. ... Testing with ROMFS shows that it is relatively easy to end up with a corrupt filesystem on the device -- eg due to the ROMFS deploy process stopping half way through -- which could lead to hard crashes. Notably, there can be boot loops trying to mount a corrupt filesystem, crashes when importing modules like `os` that first scan the filesystem for `os.py`, and crashing when deploying a new ROMFS in certain cases because the old one is removed while still mounted. The main problem is that `mp_decode_uint()` has an loop that keeps going as long as it reads 0xff byte values, which can happen in the case of erased and unwritten flash. This commit adds full bounds checking in the new `mp_decode_uint_checked()` function, and that makes all ROMFS filesystem accesses robust.

Damien George	8987b39e0b	tests/multi_net: Add test for DTLS server and client. ... This adds a multi-test for DTLS server and client behaviour. It works on all ports that enable this feature (eg unix, esp32, rp2, stm32), but bare-metal ports that use lwIP are not reliable as the DTLS server because the lwIP bindings only support queuing one UDP packet at a time (that needs to be fixed). Also, to properly implement a DTLS server sockets need to support `socket.recvfrom(n, MSG_PEEK)`. That can be implemented in the future.

Keenan Johnson	321b30ca56	extmod/modtls_mbedtls: Wire in support for DTLS. ... This commit enables support for DTLS, i.e. TLS over datagram transport protocols like UDP. While support for DTLS is absent in CPython, it is worth supporting it in MicroPython because it is the basis of the ubiquitous CoAP protocol, used in many IoT projects. To select DTLS, a new set of "protocols" are added to SSLContext: - ssl.PROTOCOL_DTLS_CLIENT - ssl.PROTOCOL_DTLS_SERVER If one of these is set, the library assumes that the underlying socket is a datagram-like socket (i.e. UDP or similar). Our own timer callbacks are implemented because the out of the box implementation relies on `gettimeofday()`. This new DTLS feature is enabled on all ports that use mbedTLS. This commit is an update to a previous PR #10062. Addresses issue #5270 which requested DTLS support. Signed-off-by: Keenan Johnson <keenan.johnson@gmail.com>	2025-02-14 12:55:25 +11:00

It implements `marshal.dumps()` and `marshal.loads()`, but only supports (un)marshalling code objects at this stage. The semantics match CPython, except that the actual marshalled bytes is not compatible with CPython's marshalled bytes.

Jeff Epler	13b13d1fdd	py/parsenum: Throw an exception for invalid int literals like "01". ... This includes making int("01") parse in base 10 like standard Python. When a base of 0 is specified it means auto-detect based on the prefix, and literals begining with 0 (except when the literal is all 0's) like "01" are then invalid and now throw an exception. The new error message is different from CPython. It says e.g., `SyntaxError: invalid syntax for integer with base 0: '09'` Additional test cases were added to cover the changed & added code.

This commit fixes a test failure for `extmod/re_sub.py` where the code, whilst being correct, would not make the test pass due to a newer Python version than expected. On Python 3.13, running `tests/extmod/re_sub.py` would yield a deprecation warning about `re.sub` not providing the match count as a keyword parameter. This warning would be embedded in the expected test result and thus the test would always fail.

Damien George	a3128f89cc	tests: Fix all file ioctl's to support only MP_STREAM_CLOSE. ... A return value of 0 from Python-level `ioctl()` means success, but if that's returned unconditionally it means that the method supports all ioctl calls, which is not true. Returning 0 without doing anything can potentially lead to a crash, eg for MP_STREAM_SEEK which requires returning a value in the passed-in struct pointer. This commit makes it so that all `ioctl()` methods respond only to MP_STREAM_CLOSE, ie they return -1 (indicating error) for all other ioctl calls.

Damien George	bdda91fe74	tests/extmod_hardware: Add a test for machine.PWM freq and duty. ... This adds a hardware test for `machine.PWM`. It requires a jumper wire between two pins, uses `machine.PWM` to output on one of them, and `machine.time_pulse_us()` to time the PWM on the other pin (some boards test more than one pair of pins). It times both the high and low duty cycle (and hence the frequency) for a range of PWM frequencies and duty cycles (including full on and full off). Currently supported on: - esp32 (needs a minor hack for initialisation, and some tests still fail) - esp8266 (passes for frequencies 1kHz and less) - mimxrt / Teensy 4.0 (passes) - rp2 (passes) - samd21 (passes for frequencies 2kHz and less) Signed-off-by: Damien George <damien@micropython.org>	2024-12-11 12:22:15 +11:00

Damien George	a2554f0957	tests/run-tests.py: Add support for tests to use unittest. ... All the existing tests require a .exp file (either manually specified or generated running the test first under CPython) that is used to check the output of running the test under MicroPython. The test passes if the output matches the expected output exactly. This has worked very well for a long time now. But some of the newer hardware tests (eg UART, SPI, PWM) don't really fit this model, for the following main reasons: - Some but not all parts of the test should be skipped on certain hardware targets. With the expected-output approach, skipping tests is either all or nothing. - It's often useful to output diagnostics as part of the test, which should not affect the result of the test (eg the diagnostics change from run to run, like timing values, or from target to target). - Sometimes a test will do a complex check and then print False/True if it passed or not, which obscures the actual test result. To improve upon this, this commit adds support to `run-tests.py` for a test to use `unittest`. It detects this by looking at the end of the output after running the test, looking for the test summary printed by `unittest` (or an error message saying `unittest` was not found). If the test uses `unittest` then it should not have a .exp file, and it's not run under CPython. A `unittest` based test passes or fails based on the summary printed by `unittest`. Note that (as long as `unittest` is installed on the target) the tests are still fully independent and you can still run them without `run-tests.py`: you just run it as usual, eg `mpremote run <test.py>`. This is very useful when creating and debugging tests. Note also that the standard test suite testing Python semantics (eg everything in `tests/basics/`) will probably never use unittest. Only more advanced tests will, and ones that are not runnable under CPython. Signed-off-by: Damien George <damien@micropython.org>	2024-12-06 13:41:52 +11:00
Angus Gratton	eb80b04944	tests/extmod: Workaround CPython warning in asyncio_new_event_loop test. ... This started failing in CI on the mingw build, after CPython updated to 3.12.7. The test prints two warnings during interpreter shutdown of "Task was destroyed but it is pending!". This didn't happen on other CPython builds, and I think that's because of finalizer order in CPython interpreter shutdown but not certain (the loop finalizer calls loop.close() if not already closed). Adding explicit calls to loop.close() causes the warning to be printed on every run with CPython 3.12.7 on Linux.
