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.
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.
An owner-qualified dependency name (Owner/Pkg, both halves safe) is the
converter's to resolve and no longer draws the malformed-entry warning,
which stays for genuinely unsafe shapes. A declared srcFilter matching
only inert files now warns like one matching nothing, while matched
headers still read as a header-only library. The short-name suppression
logs the assumed external at debug so an accidental collision is
attributable. A failing ar batch unlinks the truncated archive before
returning its exit code.
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.
The unmapped-suffix warning fired for every header-only library (the
default +<*> filter matches headers), so ArduinoJson would have warned
on every ESP8266 build. It now names exactly the source-like files
(.CPP, .ino and case-variants of the map) the case-sensitive suffix map
rejects, partial drops included, and stays quiet for headers and
metadata.
The ar shim batches the expanded object list by argv length (rc then q
appends), keeping the command line under the Windows 32767-char limit
the rspfile existed to avoid. A non-iterable dependencies value in a
manifest now warns by library name instead of raising a bare
TypeError.
