Andrew Leech	2f04381aeb	extmod/modlwip: Fix crash when calling recv on listening socket. ... Add check to prevent calling recv on a socket in the listening state. This prevents a crash/hard fault when user code mistakenly tries to recv on the listening socket instead of on the accepted connection. Add corresponding test case to demonstrate the bug.

Yoctopuce dev	e57aa7e70a	py/obj: Fix nan handling in object REPR_C and REPR_D. ... CPython math.nan is positive with regards to copysign. The signaling bit (aka sign flag) was incorrectly set. In addition, REPR_C and REPR_D should only use the _true_ nan to prevent system crash in case of hand-crafted floats. For instance, with REPR_C, any nan-like float following the pattern `01111111 1xxxxxxx xxxxxxxx xxxxx1xx` would be switched to an immediate object or a qstr string. When the qstr index is too large, this would cause a crash. This commit fixes the issue, and adds the relevant test cases. Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>	2025-06-24 00:30:08 +10:00
Yoctopuce dev	66c0148022	py/runtime: Add support for using __all__ in star import. ... When the symbol `__all__` is defined in a module, `mp_import_all()` should import all listed symbols into the global environment, rather than relying on the underscore-is-private default. This is the standard in CPython. Each item is loaded in the same way as if it would be an explicit import statement, and will invoke the module's `__getattr__` function if needed. This provides a straightforward solution for fixing star import of modules using a dynamic loader, such as `extmod/asyncio` (see issue #7266). This improvement has been enabled at BASIC_FEATURES level, to avoid impacting devices with limited ressources, for which star import is of little use anyway. Additionally, detailled reporting of errors during `__all__` import has been implemented to match CPython, but this is only enabled when ERROR_REPORTING is set to MICROPY_ERROR_REPORTING_DETAILED.

Andrew Leech	09541b7896	py/repl: Skip private variables when printing tab completion options. ... Any '_' variables/functions in frozen modules are currently printed, when they shouldn't be. That's due to underscore names possibly existing between the start and end qstrs which are used to print the auto-complete matches. The underscore names should be skipped when iterating between the two boundary qstrs. The underscore attributes are removed from the extra coverage exp file because tab completing "import <tab>" no longer lists modules beginning with an underscore.

Phil Howard	b725c26b4e	rp2/rp2_flash: Add MICROPY_HW_FLASH_MAX_FREQ to replace fixed max freq. ... Assuming a 133MHz capable flash in 91cff8e4f1 caused `rp2_flash_set_timing_internal` to set out of range dividers for some boards (anything with value of 4 and flash that doesn't tolerate higher speeds). This affected (at least) the XIAO RP2350 board, making it non-bootable. Since Pico SDK's `PICO_FLASH_SPI_CLKDIV` is entirely unreliable on a system with a variable system clock (users can change it at runtime) then use it only to work out a default `MICROPY_HW_FLASH_MAX_FREQ`. This value can be overridden in board config. Note that RP2350's default clock is 150MHz, RP2040's is 125MHz and it has been certified at 200MHz so it's quite possible that `PICO_FLASH_SPI_CLKDIV` is unreliable even at standard RP2 clocks. (If flash timings are marginal then this can manifest as instability rather than outright failure.) Fixes issue #17375. Signed-off-by: Phil Howard <github@gadgetoid.com>	2025-06-17 11:40:42 +10:00

Damien George	d9467b07cb	tools/mpremote: Improve df command to use new no-arg vfs.mount() query. ... The existing `mpremote df` command is not very good, because it needs to assume that all directories in the root directory are mount points, and also doesn't correctly stat filesystems when the current directory is not the root. This leads to wrong results With the introduction of `vfs.mount()` to return a list of mounted filesystems and their path, a much better df can be implemented, as done in this commit. The new df will also fall back to using the old approach of listing the root directory if the no-arg `vfs.mount()` query is not supported.

Jeff Epler	0ef5ede382	py/mpz: Avoid undefined behavior decrementing NULL. ... In the case where an mpz number is zero, its `len` is 0 and its `dig` is NULL. In that case, decrementing NULL via `d--` is undefined behavior according to the C specification. Restructuring the loops in this way avoids undefined behavior. Also, ensure that these cases are tested in the coverage test. This doesn't make much difference now, but would otherwise cause errors later when the undefined behavior sanitizer is employed in CI.

Damien George	2a0e2b5782	esp32/main: Auto detect the size of flash and auto create vfs partition. ... Currently in the esp32 port the size of the SPI flash must be configured at build time, eg 4MiB, 8MiB, etc. Also, the esp32 partition table must be configured at build time, which depends on the size of the SPI flash. A bigger flash means more can be allocated to the user filesystem. This commit makes it so the SPI flash size is automatically determined at runtime, and the filesystem size is automatically set to take up as much room as possible (a "vfs" partition is created automatically if it doesn't exist). This works by: - Setting the SPI flash size to be 4MiB in the build (or some other value, as long as the firmware app fits). - Removing the vfs partition from the esp32 partition table (only nvs, phy_init and firmware, and maybe romfs, remain in the partition table). - At boot, query the physical size of the SPI flash and use that as the actual size in the code. - If it doesn't already exist, automatically create a "vfs" partition which takes up the flash from the end of all existing partitions to the end of flash. This allows simplifying a lot of board configurations, and removing some board variants that just change the flash size (to be done in a following commit). It's also fully backwards compatible, in the following sense: - Existing boards with MicroPython firmware will continue to work with the same filesystem, ie the filesystem won't be erased when the firmware is updated. - If a user has a custom esp32 partition table and installs MicroPython as a bare app into the app partition, the new MicroPython firmware will honour the esp32 partition table and use either "vfs" or "ffat" partitions as the filesystem.

Prior to this commit it would measure on average about 1us lower, but now the average is much closer to the true value.
