Stop remounting adapters on shared sessions (restores dropped 429/5xx retries, ends 16-conn pool starvation, pool sized to 64); defer DRM vault write-backs off the global lock; add mux output_path groundwork for future parallelism.
Detect an encv/enca sample entry surviving decryption (moov-scoped 4CC scan) and force a repack so mkvmerge isn't first-FourCC-locked to a generic encrypted codec; warn if one persists after repacking.
Closes#142
Add is_revocation()/REVOCATION_CODES and centrally raise DeviceRevoked when a license fault carries a device/cert revocation HRESULT, so any service surfaces it without its own decoding.
Speedtest failures print an exit-code note instead of an empty section,
the report file writes progressively again (utf8 rewrite at the end),
and pytest-asyncio's py3.14 deprecation warning is filtered.
Adds machine info to the report header, multiprocess and strided-split
runs, hedge/slow-tail cases, the rnet path, and the leak regression
tests; ps1 reports save as utf8 and expected failures no longer render
as NativeCommandError blocks.
A leaked racer could retry and reopen its .!dev once dl.py cleared the
global cancel flag for the next track (WinError 32 at cleanup). A
batch-local abort event set at teardown makes its exit unconditional.
Also join terminated mp children and detect one that dies silently.
Also throttle hedge-median recompute to 0.5s, cache replace_fields format
patterns and short-circuit when no $ token, and stream HLS merge with
copyfileobj. Adds test_dash_collapse and live A/B tooling.
bench_downloader.py sweeps the unified downloader over synthetic
loopback segments (latency/rate shaping, fault injection, hedge and
sweep-safety checks) or real URLs, with --procs and --no-read1 A/B
flags. live_manifest_test.py drives the full DASH/HLS/ISM pipeline
against 11 public streams on 8 CDNs; bench-urls/ holds reproducible
real-CDN URL lists.
Unconditional read1 for every segmented download paid a per-TLS-record
Python iteration on all segments and capped single-process throughput
at ~160 MB/s (253 MB/s with blocking full-chunk reads, measured on a
fast CDN). A segment can only be claimed once a hedge racer exists for
it, so fine-grained claimed() checks are needed only during an actual
race: download() now takes a racing predicate and workers pass the
hedged-set membership check.
One CPython interpreter caps sustained segment throughput at ~160 MB/s;
spawned children each run the existing thread-pool path on a contiguous
chunk of the batch, reaching NIC line rate on fast CDNs. Opt-in via
--download-processes (default 1), engaged only for 24+ segment batches.
Sessions are rebuilt per child from a picklable spec; RnetSession falls
back to a single process when it has no impersonate preset.
Segments carrying their own Range (DASH SegmentBase, HLS EXT-X-BYTERANGE) now
fail the attempt when a server ignores the Range and returns 200, instead of
writing the whole parent resource as the segment and corrupting the merge. The
resume path no longer clobbers such a slice's Range, and retries rewrite the
slice whole. All segment GETs request Accept-Encoding: identity and the rnet
path mirrors the gzip guard, so transparent CDN (de)compression can't break the
Content-Length truncation check. Adds tests pinning these plus the adaptive
start-at-cap wiring and the small-segment tail-probe gate.
by_language now applies RFC 4647 Lookup in exact mode, preferring the string-equal tag so --exact-lang separates base/regional pairs (ar/ar-EG, en/en-US) instead of collapsing them, and dedupes by id to prevent the duplicate-track-id crash. Adds a language-selection regression test.
Merge cues at the string level instead of round-tripping through
pycaption, which dropped inline tags and cue settings. STYLE and
REGION blocks are kept, duplicate boundary cues splice correctly,
and a bad timing line now skips the cue instead of crashing.
Also rank pysubs2 above SubtitleEdit for ASS to TTML/VTT since
SubtitleEdit flattens inline styling there. Documented the measured
backend fidelity table and added regression tests for the merge.
