This commit introduces an optional feature to provide to native emitters the fully qualified name of the entity they are compiling. This is achieved by altering the generic ASM API to provide a third argument to the entry function, containing the name of the entity being compiled. Currently only the debug emitter uses this feature, as it is not really useful for other emitters for the time being; in fact the macros in question just strip the name away.

Before this commit the UART would only work in very simple use cases. Receiving large amounts of data would result in lost bytes. Plus the print function would crash due to `uart_config_get()` returning incorrect values. Additionally, receiving data with `timeout==0` would fail even if data was already available in the internal UART Rx FIFO. This commit fixes those issues. The non-implemented functions have also been made usable.

There are two changes here: 1. Increase the UART input bufffer to 512 bytes. That's necessary to get basic REPL reliability tests working, and helps improve `mpremote` usage, eg copying large files. 2. Remove `uart_sem` semaphore. This is no longer needed because `zephyr_getchar()` should be fully non-blocking and have as low a latency as possible. `mp_hal_stdin_rx_chr()` (which calls `zephyr_getchar`) already uses `MICROPY_EVENT_POLL_HOOK` to get an efficient wait, and doing an extra wait and check for the semaphore in `zephyr_getchar()` just introduces unnecessary latency and can lead to slower input, and potentially overflowing the UART input buffer.

Support for importing .mpy files is quite fundamental to MicroPython these days, eg it allows installing more efficient .mpy code via "mip install" (and installing `unittest` only works with the .mpy version because the .py version uses f-strings, which are not enabled on the zephyr port). So enable it generally for use by all boards. As part of this, also enable: - min/max: needed by `micropython/import_mpy_invalid.py`, and widely used - sys.modules: needed by `run-tests.py` to run .mpy tests with --via-mpy - io module: needed to run .mpy tests, and useful for `io.IOBase` - array slice assign: needed to run .mpy tests, and generally useful as a way to do a memory copy.

This commit adds preliminary support for ST's new STM32N6xx MCUs. Supported features of this MCU so far are: - basic clock tree initialisation, running at 800MHz - fully working USB - XSPI in memory-mapped mode - machine.Pin - machine.UART - RTC and deepsleep support - SD card - filesystem - ROMFS - WiFi and BLE via cyw43-driver (SDIO backend) Note that the N6 does not have internal flash, and has some tricky boot sequence, so using a custom bootloader (mboot) is almost a necessity.

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.

This commit adds a fast-path optimisation for when a BUILD_SLICE is immediately followed by a LOAD/STORE_SUBSCR for a native type, to avoid needing to allocate the slice on the heap. In some cases (e.g. `a[1:3] = x`) this can result in no allocations at all. We can't do this for instance types because the get/set/delattr implementation may keep a reference to the slice. Adds more tests to the basic slice tests to ensure that a stack-allocated slice never makes it to Python, and also a heapalloc test that verifies (when using bytecode) that assigning to a slice is no-alloc. This work was funded through GitHub Sponsors.

When mDNS is active on a netif it registers a lot of timeouts, namely: mdns_probe_and_announce mdns_handle_tc_question mdns_multicast_probe_timeout_reset_ipv4 mdns_multicast_timeout_25ttl_reset_ipv4 mdns_multicast_timeout_reset_ipv4 mdns_send_multicast_msg_delayed_ipv4 mdns_send_unicast_msg_delayed_ipv4 mdns_multicast_probe_timeout_reset_ipv6 mdns_multicast_timeout_25ttl_reset_ipv6 mdns_multicast_timeout_reset_ipv6 mdns_send_multicast_msg_delayed_ipv6 mdns_send_unicast_msg_delayed_ipv6 These may still be active after a netif is removed, and if they are called they will find that the mDNS state pointer in the netif is NULL and they will crash. 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.

These will run on all ports which support them, but importantly they'll also run on ports that don't support arbitrary precision but do support 64-bit long ints. Includes some test workarounds to account for things which will overflow once "long long" big integers overflow (added in follow-up commit): - uctypes_array_load_store test was failing already, now won't parse. - all the ffi_int tests contain 64-bit unsigned values, that won't parse as long long.

If big integer support is 'long long' then mp_parse_num_integer() can parse to it directly instead of failing over from small int. This means strtoll() is no longer pulled in, and fixes some bugs parsing long long integers (i.e. can now parse negative values correctly, can now parse values which aren't NULL terminated). The (default) smallint parsing compiled code should stay the same here, macros and a typedef are used to abstract some parts of it out. When bigint is long long we parse to 'unsigned long long' first (to avoid the code size hit of pulling in signed 64-bit math routines) and the convert to signed at the end. One tricky case this routine correctly overflows on is int("9223372036854775808") which is one more than LLONG_MAX in decimal. No unit test case added for this as it's too hard to detect 64-bit long integer mode. This work was funded through GitHub Sponsors.

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.

This thread stress test is quite intensive and can run for a long time on certain targets. For example, builds with stackless enabled are slower than non-stackless, and this test in stackless mode takes around 2 minutes on the unix port of MicroPython with the existing parameters of `n_thread=20` and `n_loop=5`. It's not really necessary to test 20 threads at once, that's not really going to test anything more than 10 at once. So reduce the parameters to keep the running time reasonable.

If threading is available, add the thread tests to the set of tests to run (unless the set of tests is explicitly given). With this change, the unix port no longer needs to explicitly run the set of thread tests, so that line has been removed from the Makefile.

For some tests (eg `thread_coop.py`) the whole point of the test is to test that the GIL is correctly bounced. So for those cases force the use of the bytecode emitter for the busy functions.

The `run-perfbench.py` test is run as part of CI, but the actual performance results are not used. Rather, the test is just testing that all the performance tests run correctly. So there's no need to run with the default averaging of 8 (which runs each test 8 times and takes the average time for the performance result) which can take a lot of time for slower builds, eg unix sanitize, settrace and stackless builds. This commit changes the averaging to just 1.

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. This commit changes the sendbreak implementation to just reconfigure the TX pin as GPIO in output mode, and hold the pin low for the required duration.

With the recent update to ESP-IDF 5.4.2, there is a change in BLE event behaviour which makes `tests/multi_bluetooth/ble_mtu.py` and `tests/multi_bluetooth/ble_mtu_peripheral.py` now fail on ESP32 with IDF 5.4.2. The change in behaviour is that MTU_EXCHANGE events can now occur before CENTRAL_CONNECT/PERIPHERAL_CONNECT events. That seems a bit strange, because the MTU exchange occurs after the connection. And looking at the timing of the events there is exactly 100ms between them, ie MTU_EXCHANGE fires and then exactly 100ms later CENTRAL_CONNECT/PERIPHERAL_CONNECT fires. It's unknown if this is a bug in (Espressif's) NimBLE, a subtle change in scheduling with still valid behaviour, an intended change, a change allowed under the BLE spec, or something else. But in order to move forward with updating to IDF 5.4.2, the relevant tests have been adjusted so they can pass. The test just needs to wait a bit between doing the connect and doing the MTU exchange, so the other side sees the original/correct ordering of events.

This is already enabled in the ESP-IDF mbedTLS config, so provide an implementation of the cookie store functions. This allows DTLS connections between two esp32 boards. The session cookie store is a very simple dictionary associated with the SSLContext. To work, the server needs to reuse the same SSLContext (but cookies are never cleaned up, so a server with a high number of clients should recycle the context periodically.) Server code still needs to handle the MBEDTLS_ERR_SSL_HELLO_VERIFY_REQUIRED error by waiting for the next UDP packet from the client.

This is an annoying regression caused by including mpconfig.h in 36922df - the mimxrt platform headers define ARRAY_SIZE and mbedtls also defines in some source files, using a different parameter name which is a warning in gcc. Technically mimxrt SDK is to blame here, but as this isn't a named warning in gcc the only way to work around it in the mimxrt port would be to disable all warnings when building this particular mbedTLS source file.

Back in LFS2 version 2.6 they updated the on-disk version from 2.0 to 2.1 which broke back compatibility (aka older versions could no long read new version disk format), see https://github.com/littlefs-project/littlefs/releases/tag/v2.6.0 Then in LFS2 v2.7 an optional `config->disk_version` was added to force the library to use an older disk format instead, see: https://github.com/littlefs-project/littlefs/releases/tag/v2.7.0 This commit simply exposes `config->disk_version` as a compile time option if LFS2_MULTIVERSION is set, otherwise there is no change in behavior. This is Useful for compatibility with older LFS versions. Note: LFS2_MULTIVERSION needs to be defined at the make / CFLAGS level, setting it in mpconfigboard.h doesn't work as it's not included in the `lfs2.c` file in any way.

Current implementation of REPR_C works by clearing the two lower bits of the mantissa to zero. As this happens after each floating point operation, this tends to bias floating point numbers towards zero, causing decimals like .9997 instead of rounded numbers. This is visible in test cases involving repeated computations, such as `tests/misc/rge_sm.py` for instance. The suggested fix fills in the missing bits by copying the previous two bits. Although this cannot recreate missing information, it fixes the bias by inserting plausible values for the lost bits, at a relatively low cost. Some float tests involving irrational numbers have to be softened in case of REPR_C, as the 30 bits are not always enough to fulfill the expectations of the original test, and the change may randomly affect the last digits. Such cases have been made explicit by testing for REPR_C or by adding a clear comment. The perf_test fft code was also missing a call to round() before casting a log_2 operation to int, which was causing a failure due to a last-decimal change.

The recently merged 5e9189d6d1c00c92694888bf9c74276779c40716 now allows temporary slices to be allocated on the C stack, which is much better than allocating them on the GC heap. Unfortunately there are cases where the C-allocated slice can escape and be retained as an object, which leads to crashes (because that object points to the C stack which now has other values on it). The fix here is to add a new `MP_TYPE_FLAG_SUBSCR_ALLOWS_STACK_SLICE`. Native types should set this flag if their subscr method is guaranteed not to hold on to a reference of the slice object. Fixes issue #17733 (see also #17723).

The type of the argument must match the format string. Add casts to ensure that they do. It's possible that casting from `size_t` to `unsigned` loses the correct values by masking off upper bits, but it seems likely that the quantities involved in practice are small enough that the `%u` formatter (32 bits on most platforms, 16 on pic16bit) will in fact hold the correct value. The alternative, casting to a wider type, adds code size. These locations were found using an experimental gcc plugin for `mp_printf` error checking, cross-building for x64 windows on Linux. In one case there was already a cast, but it was written incorrectly and did not have the intended effect.
