RnetCookieAdapter stores cookies by domain, path and name and sends path, secure and a leading-dot domain to rnet. It also takes server-rotated values, and worker children and track sessions get the cookies with their paths.
The session message names the host, not the signed URL, and a segment that fails every attempt prints one line with no traceback. API job errors come from the exception.
--proxy now overrides HTTP(S)_PROXY and the Windows system proxy while keeping the env CA bundle. Core fallback sessions use the run's proxy, and a warn-only audit hook names service code that sends a request or opens a raw socket outside the proxy; a session with proxy_exempt = True opts out.
Test servers shut down without the 0.5s poll wait, unit tests refuse non-loopback lookups, and three load-sensitive tests are steadied. Pushes to dev test Python 3.11 only; the docs job builds with uv.
Assert that an empty body of unknown length, a 206 with no complete length, and a 206 starting past the resume offset each fail instead of finalizing, and that every restart path spends an attempt.
Assert that verify, params, cert and auth reach a spawned child, and that a mounted adapter the child cannot reproduce falls back to the single-process path. Documents --download-processes in the CLI reference.
Assert that a probe is judged on the trailing tick, that a backoff is temporary and climbs back to the cap, and that a worker always finds its next segment staged. Documents adaptive-workers behaviour in the downloading guide.
Check a sequential download against the complete length whenever one is known, and settle the unknown-total case on the 416. An empty body of unknown length, a 206 with no complete length, and a 206 starting past the resume offset all passed the size checks before and were renamed into place. Four restart paths spent no attempt, so a host that always answered the same way cycled forever.
Handlers share one service instance, so a per-session lock keeps two requests out of it at once. Track threads merge and write job state under one lock, and the progress sink coalesces ticks that say the same thing.
Request 4 MiB sub-ranges once a host cuts a body, skip the session's own urllib3 Retry inside download(), fail the ranged path at once on a 4xx, and cap resumes at 50 of 1 MiB each. Adds a deny fault profile.
RFC 9110 clamps a range end past the resource to its last byte; the guard
rejected that valid response. The descriptive-audio filter also had no
emptiness check, so a title with only described audio failed with a
misleading missing-language error.
Submitting every segment up front convoyed on ThreadPoolExecutor's process-global lock, starving the event drain so per-track progress bars only advanced once the download had finished.
Renames 314 defs and 41 module/class-level constants. Keeps 11 names underscored where the stripped form collides in scope, plus 5.5.0 shims for the three symbols external service repos call.
RFC 9110 permits a server to ignore Range and answer 200 with the whole
resource. When the item's slice starts at byte 0 and spans exactly the
response body, that 200 is byte-identical to the 206, so keep it instead of
burning all five attempts and failing the track. Every other 200 (nonzero
start, span mismatch, open-ended, encoded) still fails the attempt to
protect the merge.
The rnet branch zeroed content_length only for gzip/deflate/br, so an
unknown coding (zstd, future tokens) kept a bogus length and, worse, the
drop-the-partial-instead-of-Range-resuming guard could never fire on the
rnet path because content_encoded stayed False. Use the same fail-closed
_is_content_encoded check the requests branch uses.
Any batch failure sets the process-global DOWNLOAD_CANCELLED, which
TokenBucket.consume waits on, so a test elsewhere could void every timing
assertion here; add the autouse clear fixture the other downloader test
modules already use. Also capture the debt sleep via a stub instead of
timing a real Event.wait, whose occasional spurious early wake tripped the
1.0s lower bound.
Spawned children re-import the module and start with no TokenBucket, so
--download-processes silently dropped a configured --speed-limit /
global_speed_limit for any 24+ segment batch. Fall back to the in-process
path while a limit is set (same gate as the ranged-parallel paths), log the
fallback, and document the interaction.
Catch the branch up with dev (45 commits) so testers can run the perf work
against current dev.
Conflict resolutions:
- downloaders/requests.py: keep the branch's racing-gated read1, adaptive
controller speed reporting and byte-range slice guards; take dev's
content-encoding checks (raw reads are skipped on an encoded body) and its
rolling SpeedWindow for the no-controller speed fallback. The single-URL
ranged-parallel gate now requires no speed limit and no caller Range.
- service.py / session.py: keep the branch's TimeoutHTTPAdapter and retry
config, raise POOL_MAX_SIZE to 64 so dev's pool-starvation fix survives
(pool_block=True stalls threads on a pool smaller than the in-flight count).
- docs: dev split configuration.md into per-area pages, so the branch's rnet
network option rows moved to reference/configuration/network.md.
Reading .raw skips urllib3's decoding, so brotli-served subtitles landed compressed and converted to empty files. Also drops a partial rather than Range-resuming an encoded body, since a Range indexes the encoded bytes.
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.
