stmhal Frozen bytecode: no longer works with lib subdirectory

closedby peterhinchopened 2017-02-21updated 2017-02-27

I have stmhal/modules/lib containing the uasyncio library. I have been building successfully with

make -j 8 BOARD=PYBV11 FROZEN_MPY_DIR=modules

Today, though it compiled the files

...
MPY modules/lib/uasyncio/test2.py
MPY modules/lib/uasyncio/core.py
MPY modules/lib/uasyncio/__init__.py
MPY modules/lib/uasyncio/test.py
MPY modules/lib/uasyncio/queues.py
MPY modules/lib/collections/deque.py
...

I can no longer import uasyncio at the REPL. Modules in stmhal/modules (i.e. not in the subdirectory) are OK.

Assessment

S Sonnet · high

Both involve uasyncio import failures, but the root causes are entirely different. The query (#9048) is about a .mpy file format version mismatch when installing via Thonny Package Manager — the installed .mpy was compiled for a different MicroPython ABI than the running firmware. The candidate (#2892) is about frozen bytecode in subdirectories not being importable at runtime on stmhal due to directory hierarchy handling in the build system. Shared component (uasyncio) and symptom (import fails), but different mechanisms and different contexts (package manager vs frozen build system).

Suggested action

No action needed between these two items. They can be tracked independently. The query (#9048) should be investigated for .mpy ABI versioning and package manager compatibility, not as a duplicate of this build system issue.
