When a frozen module was added or updated, a build error would occur
during CI: `KeyError: 'FROZEN_MPY_DIRS'`.
In e40abda1bc I decided that it should be an error if all the expected
keys were not defined in the board settings dict. I made this change
and all seemed to be well; however, my testing did not exercise the
case that a frozen module was changed.
It turns out that FROZEN_MPY_DIRS was not being set in the board settings
dict because the output of print-FROZEN_MPY_DIRS was "FROZEN_MPY_DIRS ="
(which does not match the regular expression) instead of
"FROZEN_MPY_DIRS = " (with a trailing space).
This change fixes the problem by ensuring that an undefined or empty
variable still prints with a space character after the equal character.
Tested by running locally:
```
python3 -c 'import shared_bindings_matrix; print(shared_bindings_matrix.get_settings_from_makefile("ports/atmel-samd", "trinket_m0")["FROZEN_MPY_DIRS"])'
```
(prints a blank line, expected)
as well as simulating a change to the asyncio frozen submodule:
```
python3 -c 'import shared_bindings_matrix; print(shared_bindings_matrix.get_settings_from_makefile("ports/atmel-samd", "trinket_m0")["FROZEN_MPY_DIRS"])'
```
(which will build the elecfreaks_picoed board)
This returns the localization of the running CircuitPython, such as
en_US, fr, etc.
Additional changes are needed in build infrastructure since the
string "en_US" should not appear to be translated in weblate, ever;
instead the value comes from the translation metadata.
Closes: #8602
* teach ci_fetch_deps about --filter=blob:none
* change logic ensuring tags in frozen/ are fetched
* since check=True was all the time, remove unused kwarg
* add fetch-board-submodules
Closes: #8588
This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.
On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.
This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.
Fixes#8512. Fixes#7334.
micropython puts the pointer-ness into the typedef; we can put the
const-ness there too.
this reduces the delta to micropython; for instance, emitinlinextensa
and emitinlinethumb now match upstream.
These are moved:
* Display -> busdisplay.BusDisplay
* FourWire -> fourwire.FourWire
* EPaperDisplay -> epaperdisplay.EPaperDisplay
* I2CDisplay -> i2cdisplaybus.I2CDisplayBus
`paralleldisplay` is now `paralleldisplaybus` (and registered as
`paralleldisplay` too).
Bus related helpers are split out of display_core into bus_core.
It is in still displayio since it is a dependency of both
busdisplay and epaperdisplay.
Fixes#7667
to trade compile speed & flash size
Initially enable the faster mode on rp2040 and espressif, where there's
usually plenty of flash available (these advanced techniques save hundreds
to thousands of bytes, which is important on a lot of old samd21 boards
but is a drop in the lake of a 4MB flash chip)
