There is a race between when we run background tasks and when we
sleep. If an interrupt happens between the two, then we may delay
executing the background task. On some ports we checked this for
TinyUSB already. On iMX RT, we didn't which caused USB issues.
This PR makes it more generic for all background tasks including
USB.
Fixes#5086 and maybe others.
* The new nonstandard '%S' format takes a pointer to compressed_string_t
and prints it
* The new mp_cprintf and mp_vcprintf take a format string that is a
compressed_string_t
By storing "count of words by length", the long `wends` table can be
replaced with a short `wlencount` table. This saves flash storage space.
Extend the range of string lengths that can be in the dictionary.
Originally it was to 2 to 9; at one point it was changed to 3 to 9.
Putting the lower bound back at 2 has a positive impact on the French
translation (a bunch of them, such as "ch", "\r\n", "%q", are used).
Increasing the maximum length gets 'mpossible', ' doit être ',
and 'CircuitPyth' at the long end. This adds a bit of processing time
to makeqstrdata. The specific 2/11 values are again empirical based on
the French translation on the adafruit_proxlight_trinkey_m0.
Call `supervisor.disable_ble_workflow()` and the BLE workflow will
be disabled until the chip is reset.
This also includes a couple fixes:
1. Terminals can now be deinit by setting the tilegrid to NULL. This
prevents using the tilegrid before display is init.
2. Fix BLE serial send amount when sending more than a single packet.
Fixes#5049
nRF CircuitPython boards will now provide the file transfer
service defined here: https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer
USB capable boards will only advertise if previously bonded to a
device or if the reset button is pressed during the fast blue
flashes on start up. When pressed, the board will restart again but
the blue period will not flash.
Boards without USB will always advertise.
When previously bonded, the advertisement is private so that no
other peers can connect. If advertising publicly, the tx power is
lowered to reduce the likelihood of bonding from a distance.
This PR also fixes issues with loading identities of bonded peers
so that our address can now be resolved and we can resolve others'
addresses when scanning.
It was possible for _only_ a low allocation to be performed.
In this case, `high_head` is NULL, and the comparison
`MP_STATE_VM(first_embedded_allocation) < high_head` would fail.
Closes: #4871
This also removes the need to pin share because we don't use the
status LED while user code is running.
The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.
One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.
Fixes#4133
* modframebuf: _mp_framebuf_p_t is not "really" a protocol, but the
QSTR assignment caused problems when building as a dynamic module
* modure: str_index_to_ptr is not in the natmod API, disable URE match
spans when dynamic. mp_obj_len() is a bugfix, we should throw here
if the object is not string-like
* moduzlib: Correct paths to uzlib headers & sources. this relative
path (from moduzlib.c to the referenced file) works in all cases,
the other only worked from ports/PORTNAME.
* dynruntime: Handle 2-arg m_malloc, assert_native_inited, add a
micropythonish mp_arg_check_num_mp, fix mp_raise_msg to use dumb
strings, add mp_raise_arg1
* nativeglue: ad assert_native_inited
* translate: MP_ERROR_TEXT evaluates to its argument for DYNRUNTIME
* mpy-tool: A straggling magic number change
* mpy_ld: Have to renumber manually after dynruntime change
* import_mpy_native_gc.py: Update copy of features0 baked into this test
When `reload_requested` is detected, the run reason will no longer be
automatically overwritten as an AUTO_RELOAD, making SUPERVISOR_RELOAD a
detectable reload reason. Autoreload now sets the reload reason itself.
After discussing with danh, I noticed that `a/**/b` would not match `a/b`.
After correcting this and re-running "pre-commit run --all", additional
files were reindented, including the codeformat script itself.
In #4683, tannewt noticed that uncrustify was not running on some
file in common-hal.
I investigated and found that it was not being run on a bunch of paths.
Rather than make incremental changes, I rewrote list_files to work
bsaed on regular expressions; these regular expressions are created from
the same git-style glob patterns.
I spot-checked some specific filenames after this change, and all looks good:
```
$ python3 tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c
tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c
uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup extmod/virtpin.c ports/raspberrypi/background.h ports/raspberrypi/common-hal/pulseio/PulseIn.c
black --fast --line-length=99 -v tests/thread/thread_exit1.py
```
recursiveloop and int_small are excluded, while PulseIn, virtpin,
and background are included.
Testing running from a subdirectory (not _specifically_ supported though):
```
(cd ports && python3 ../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c)
../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c
uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup ../extmod/virtpin.c raspberrypi/common-hal/pulseio/PulseIn.
```
As a side-effect, a bunch more files are re-formatted now. :-P
Unify USB-related makefile var and C def as CIRCUITPY_USB.
Always define it as 0 or 1, same as all other settings.
USB_AVAILABLE was conditionally defined in supervisor.mk,
but never actually used to #ifdef USB-related code.
Loosely related to #4546
The interrupt may have a higher priority than the serial output's
(USB) interrupt and may never make room. This makes prints from
interrupts (like the BLE event calls) best effort for what can be
queued up. The rest of the output will be dropped.
This allows the compiler to merge strings: e.g. "update",
"difference_update" and "symmetric_difference_update"
will all point to the same memory.
Shaves ~1KB off the image size, and potentially allows
bigger savings if qstr attrs are initialized in qstr_init(),
and not stored in the image.
This manifested as incorrect error messages from mpy-cross, like
```
$ mpy-cross doesnotexist.py
OSError: [Errno 2] cno such file/director
```
The remaining bits in `b` must be shifted to the correct position before
entering the loop.
For most (all?) actual builds, compress_max_length_bits was 8 and the
problem went unnoticed.
