The library prefetch pool now cancels queued futures on interrupt like
the espidf pool it mirrors, prefetch and HEAD failures log their cause
at debug (a suppressed bar is traceable), and non-2xx HEAD statuses read
as unknown size. normalize_dependencies rejects a non-string version in
both spellings (a container would raise from set.add(); an int fails
opaquely in the registry), and the walk's version-less skip logs the
dependency at debug until the arduino-backend reconciliation lands.
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.
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.
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.
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.
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 switch from cyw43_tcpip_link_status to cyw43_wifi_link_status
was intended for 2026.3.0 alongside the arduino-pico 5.5.0 framework
update but was accidentally included in 2026.2.3.
With the old framework (3.9.4), cyw43_wifi_link_status never returns
CYW43_LINK_UP, so the CONNECTED state is unreachable. The device
connects to WiFi but the status stays at CONNECTING until timeout,
causing a connect/disconnect loop.
