The comment says it is `buffer[start:end]` but it assumed elements
were a single byte long. Now it correctly does multibyte elements
from array.array.
Fixes#4988
We adopted the file "py/ioctl.h" and the ioctl names beginning
with MP_IOCTL_POLL while micropython went with "py/stream.h" and
MP_STREAM_POLL.
Align with upstream.
Closes#6711
Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
This object has a finalizer, so once it's no longer referenced, GC can
call that finalizer and then deallocate the storage.
In the case of a failure during construction (e.g., when checking
`validate_obj_is_free_pin_or_none`) this will happen on an incompletely
initialized structure. On samd, in particular, a newly allocated object
(with construct never called) appears to be valid, so GC collecting it
causes deinit() to do things, leading to a hard fault.
The double creation of the UART object was necessary specifically so that
the second allocation would fail. Probably there were other (single
call) ways to make it fail, but this was the easiest / the one discovered
in real life.
Closes: #5493
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
