An unknown Content-Length (probe failure, non-2xx, or a CDN omitting it
on HEAD) now skips the parallel prefetch so the sequential downloads
keep their per-file bars, instead of a silent multi-MB batch; the HEAD
helper returns None for unknown, distinct from a genuine zero, and
catches only RequestException. The cache probe logs its failure at
debug. The espidf tool prefetch reads sizes with .get so a missing size
only drops the bar instead of aborting the resumable prefetch. The
idedata warning logs its traceback at debug for parser regressions, and
framework_helpers joins the ESP-IDF infra CI triggers it is imported
by.
A bundled manifest relying on an extraScript, or any manifest declaring
precompiled/ldflags, now raises naming the library instead of warning
into a link failure far from the cause. The backend-side usability
re-check logs all InvalidLibrary causes at debug with an accurate
comment: the walk runs dependency_is_usable on every versioned entry
before the provides() skip, so the fault always warns there first (a
real-converter test pins the once-only warning). build_tool handles a
missing subcommand with its named error instead of an IndexError.
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.
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.
