Change Description

MultiBuildTargetEnumerator and RecursiveMultiBuildTargetEnumerator now drop duplicate lines from build-targets.fprime-util / tests.fprime-util / sub-directories.fprime-util, keeping first-seen order (dict.fromkeys). Tests added with a duplicate-entry fixture.

Rationale

Older fprime versions re-append the root directory's metadata on every CMake re-configure, so fprime-util build runs ninja all (and the <Deployment>_dictionary install) once per duplicate. The root cause is fixed in fprime (JPL-Devin/fprime#277); this makes fprime-util tolerant of build caches generated by frameworks without that fix.

Testing/Review Recommendations

pytest test/fprime/fbuild/test_enumerators.py.

Future Work

None.

I'll fix CI failures and address comments from users with write access that start with 'Devin'.

• Disable automatic comment, CI, and merge conflict monitoring

Original prompt from thomas.boyer.chammard

Sometimes when running a build, it'll kind of loop over the dicitonary install. See

I think it happens more often when using VxWorks (fprime-vxworks library and platform), but I'm not sure. Can you try to reproduce and diagnose and fix?

Closing: the duplicate metadata entries are fixed at the source in JPL-Devin/fprime#277, so this consumer-side dedupe is not needed.
