copy_src_tree is always mocked in the writer tests, so the new
missing/stale/unreadable debug branches were unreachable; the decision
moves into _build_info_stale with a test covering every branch.
voluptuous fills schema defaults in set-iteration order, so the
validated dict's key order changes with the process hash seed; the
unsorted dump churned the comment block in main.cpp and relinked the
firmware on every esphome run for any config using a defaults-heavy
action (logger.log in a button's on_press was enough). Affects the
PlatformIO path identically.
Every sources_changed site now logs which file (or which build-info
staleness) triggered it, so a config that relinks on every run can be
diagnosed from one -v compile instead of diffing the build tree.
A framework tree without libraries/ now raises naming the path instead
of silently rerouting every bundled name to the registry, matching the
empty-bundled-dir error. check_library_data accepts framework=None to
skip the framework check (mirroring platform=None), so the backend-side
platform re-check no longer re-fires the frameworks-mismatch warning
the walk already emitted. The platform-rejection-is-debug test patched
the wrong module and asserted nothing; it now patches the backend's
import and asserts the dependency is absent from the resolved set.
A -n dry-run probe answers 'no work to do' without the real ninja spawn,
and running with cwd instead of -C drops the 'Entering directory' banner
on real builds too.
The walk now drains its frontier, prefetches the wave's registry
archives with a small thread pool (deduped by URL, progress bars
suppressed per thread since parallel bars would interleave), and then
processes the wave sequentially; the sequential download() call stays
authoritative so failures surface with resume exactly as before. Same
approach as the espidf tool prefetch in #18513.
voluptuous accepts [] for [cv.string], so vals[-1] could raise an
IndexError at codegen time; an empty list now falls through to the
ignored-option warning.
The backend-side bundled filter now checks compatibility silently (the
shared walk owns the warning), so one manifest fault warns once instead
of twice. Bundled-name membership uses the exact on-disk directory
names instead of a per-name is_dir() probe, so a case-insensitive
filesystem cannot match a case-mismatched dependency and build the same
bundled library twice.
