I am getting a merge error I think in the test unix build. Digging through all the make files it seems the end of the test calls a custom make command including -DMP_CONFIGFILE="<mpconfigport_coverage.h>

This coverage file defines: #define MICROPY_PY_COLLECTIONS_NAMEDTUPLE__ASDICT (1) and the only place in all the source code it appears is here.

The one (and only) function this define includes references the ORDEREDDICT define that was moved to a central area. py/circuitpy_mpconfig.mk is never included in the unix build (it is in all the others). So the new define is never included.

I am sure if I include a define in mpconfigport_coverage.h the issue will go away but gets away from centralization.

I am not familiar enough with the whole build setup to want to make that choice on my own though. So any thoughts? If this isn't clear just ping me on discord.

Ya, that's a weird thing to define. Maybe just remove it and replace the uses with checking if ordereddict is enabled?

New problem, on a small number of boards, for certain translations the build is failing. These are all M0 builds that were not set to CIRCUITPY_FULL_BUILD = 0 so they are building with more features then the other M0 boards. But for some build translations are running out of flash.

By moving ORDEREDDICT to a central location it was using the FULL_BUILD define. I could introduce a new define but then we are almost back to where we started from, except instead of per port build specifications it would not be per board.

Also for some reason this compiles on my PC in all these configurations but not in github actions.

So basically it's failing on SAMD21 express builds with a few translations. We can try to squeeze those particular translations by setting CFLAGS_INLINE_LIMIT lower. If you look at the way CFLAGS_INLINE_LIMIT is used in the various mpconfigboard.mk files, you can see some existing examples. Or we can simply disable it for all SAMD21 builds.

So I'd say let's just not implement ordered dicts for SAMD21's. @tannewt How do you feel about that?

Overall, I'm ok with that. We only need it for the BLE library as far as I know: adafruit/Adafruit_CircuitPython_BLE#97

I'll undo those changes. Is there a pattern to use to exclude a feature only from SAMD21 I can copy?

In circuitpy_mpconfig.h, you can just guard the definition so that if it's already defined in mpconfigport.h, then you don't redefine it:

#ifndef MICROPY_PY_COLLECTIONS_ORDEREDDIRECT
#define MICROPY_PY_COLLECTIONS_ORDEREDDICT    (CIRCUITPY_FULL_BUILD)
#endif

MICROPY_PY_URE is guarded in a similar way.

Thanks for your patience in working throgh this!
