The wave logged 'Downloading N libraries' before checking the
extraction markers, so a warm build announced downloads it never made.
URLSource gains an is_cached probe (best-effort in the prefetch) and a
fully warm wave stays silent.
A URL-pinned dependency now skips the bundled probe (the walk resolves
the fork; adding the bundled copy would double the archive). A versioned
bundled candidate's non-platform manifest fault warns here since it
skips the walk's usability filter via provides(); version-less causes
stay at debug (the walk already warned). The pending drain logs a
manifest-name suppression at debug and drops its unreachable
bundled_names re-check. A converted tree with no sources and no headers
now fails by name at emit like the bundled case (test scaffolds gained
real source files). build_tool validates each mode's operand count and
a failed copy unlinks the partial output.
Brings in #18513 (BatchDownloadProgress and the download_with_resume
progress callback) and extends the plumbing one level:
download_from_mirrors passes a progress callback to both target kinds,
Source/ConvertedLibrary.download thread it through, and the library
wave prefetch draws one combined bar sized by parallel HEAD requests
(no sizes, no bar). The thread-local bar suppression this replaces is
removed; a batch caller passing a tracker also owns the messaging, so
the per-file Downloading line only prints for solo downloads.
A dependency whose version is a repository URL names one specific
source, so it is now detected before the backend-provided skip and
resolves as git instead of being replaced by the bundled copy. The
library header-suffix set becomes LIBRARY_HEADER_SUFFIXES so it cannot
shadow esphome.const's narrower HEADER_FILE_EXTENSIONS. Suppressing a
genuinely bundled name on an external short-name match warns (an
accidental collision would surface as link errors), a converted library
with no sources and no headers warns by name, and the walk's
unreachable nameless-dependency check is gone.
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.
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.
