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.
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 schema permits the list form, so the routing now stores the last
value (like a later platformio.ini line) and the generator always sees a
scalar. The using_native_toolchain docstring points at write_cpp_file's
dispatch so NATIVE_TOOLCHAINS membership and the project-writing branch
flip together.
parse_enable_env's inline tuples become TRUTHY_ENV_STRINGS and
FALSY_ENV_STRINGS frozensets mirroring cv.boolean's spellings (enable
and disable included) plus the 1/0 env convention, matching
device-builder's TRUTHY_BOOL_STRINGS pattern.
The typed IncompatiblePlatform exception, dependency_is_usable,
warn_properties_depends, the lex_build_flags helper (espidf switches to
it), the normalize_dependencies validation, the manifest shape check,
the component-level drop-warning split, and the SCons case-sensitive
.C/.C++ suffixes all harden the shared converter independently of the
arduino backend, so they belong in this PR; the provides hook and the
version-less reconciliation stay with the backend that needs them.
toolchain_tool carries the bin/xtensa-lx106-elf-<name> pattern and the
Windows suffix that four call sites previously spelled out (only one of
which handled the suffix). ccache_env and get_build_env accept the
already-resolved ccache path so run_compile can resolve once instead of
paying the PATH scan and runnability probe three times per build.
Published configs override it to reserve a filesystem region
(SmartIntercom's eagle.flash.4m2m.ld) or to correct a board's assumed
flash size (2 MB ESP8285 plugs pinning eagle.flash.2m.ld); dropping it
changes the flash layout under them.
Dropping it was a real regression: many published ESP8266 configs pin
board_build.f_cpu: 160000000L for timing-sensitive integrations
(MHI-AC-Ctrl documents the 160 MHz requirement in its example), and the
warn-and-drop left those devices at 80 MHz. The option now routes into
CORE.platformio_options under toolchain: arduino for the generator to
consume; other native toolchains keep the warning.
functools.cache froze the ESPHOME_CCACHE_ENABLE/PATH decision for the
process lifetime, which a long-lived host like device-builder never
restarts, and forced a cache_clear fixture in the tests. The docstring
and test now pin the uncached delegation.
