chore(quest): plan the m1 quests that had no real plan - #3343
Conversation
Replan the m1 quests that were still issue-body placeholders or carried an open fork, and abandon two whose premise no longer holds. - #816: idle timeout, keep-alive, and the congestion-control family already exist on quic::Client/quic::Server. The quest narrows to flow-control windows, three byte fields wired to every backend, applied or refused. - #1059: abandoned. MSF draft-01 defines only inline init data and CMSF-00 requires the CMAF header base64 in the catalog entry, so init tracks would diverge from the spec we are aligning with. - #2708: abandoned. Prefix routes (#3225) on dev removed the need for a lazy announce interest, and the two implementations were closed unmerged. - #2709: reframed as mirroring dev's send-side bandwidth allocator into js/net, receive side out of scope. - #2979: decided to make backend-less and tcp-only builds compile, drop the moq-rtmp quinn dev-dep pin once tls builds without a backend, and add cargo-hack per-crate checks to nightly. - #3190: settled the announce design and split it. A new announce-handle quest folds dynamic() into announce(prefix, route) and keeps create_broadcast plus set_announce for local content; #3190 becomes the bindings alignment on top of it; a new js-announce quest mirrors it in js/net.

Deferring Dart until the dev-to-main merge leaves required work with no durable owner once this quest is completed and deleted. The current dart/moq/lib/moq.dart still documents createBroadcast as create-and-announce, and dart/moq/test/moq_test.dart expects that immediate announcement, so merging the new FFI semantics without a separate merge-gating quest will leave the Dart wrapper and docs behaviorally stale. Create a follow-up quest for the Dart wrapper, generated bindings, tests, and doc/lib/dart rather than leaving the work only in this sentence. (Written by GPT-5.6 Sol)

This plan transfers the C request-serving API into #3190, but quest/m1/2152-libmoq-c-abi-catch-up-with-the-moq-ffi-surface.md still lists dynamic broadcast serving and requested_broadcast as remaining work. Because #2152 has no blocker, after this quest deletes MoqOriginDynamic it remains ready and directs another implementer toward the obsolete shape or duplicate accessors. Re-scope #2152 in this change so the two independently executable quests have non-overlapping outcomes. (Written by GPT-5.6 Sol)

Address the Codex review on #3343: the Dart wrapper's move to the new announce surface gets its own quest gated on the dev merge instead of a sentence in #3190, and #2152 stops listing broadcast request serving now that the bindings quest delivers it to C.

- Around line 5-9: Narrow the Goal statement to specify that each video
publisher’s encoder targets its own share of the send-rate estimate, keeping
audio grant-following out of scope as stated in the plan.
- Around line 36-39: Extend the plan to specify how each 100 ms
estimatedSendRate sample updates the existing shared Allocator and recomputes
grants for all active reservations without recreating or discarding its
registry. Add a test that changes the estimate while reservations remain active
and verifies their grants are recalculated.
- Around line 32-35: Update the JavaScript bandwidth plan around Reservation and
allocator lifecycle to define an explicit release or dispose operation, and
invoke it from track/encoder cleanup and connection-close paths so closed tracks
are removed before reloads. Add a test covering close followed by reload and
verifying the released reservation no longer reduces later grants.
In `@quest/m1/2979-moq-tokio-does-not-compile-with-no-default-features-and.md`:
- Around line 41-42: Update the moq-tokio validation command in the `just rs
features` documentation to either add a bounded `--feature-powerset` check that
covers required feature combinations such as `tcp+quinn`, or explicitly narrow
the stated validation goal to individual feature builds so it matches
`--each-feature` behavior.
In `@quest/m1/3190-align-origin-broadcast-creation-naming-across-language.md`:
- Around line 37-38: Update the create_broadcast wrapper docstring in origin.py
so it describes creation as unadvertised, removing the claim that it starts live
or announces the path; keep the inline documentation consistent with the new
contract and the related library docs.
- Around line 11-15: Define a consistent producer-teardown contract across all
bindings for finish, close, and wrapper destruction, specifying whether each
action immediately retracts the advertisement or intentionally leaves it active.
Align the announce-handle documentation and binding behavior with this contract,
then add lifecycle tests covering each teardown path in every binding.
In `@quest/m1/816-expose-transportconfig.md`:
- Around line 43-44: Make the send_window validation backend-specific: preserve
it for Quinn, noq, and iroh, but reject it with a configuration error during
quiche client or server construction rather than in the shared Resolved
resolution path. Ensure quiche cannot silently ignore the setting and both
quiche construction paths apply the same refusal behavior.
- Around line 45-47: Ensure the iroh configuration path does not silently ignore
server-side QUIC window settings: either pass quic::Server into the shared iroh
endpoint and apply server.quic.receive_window,
server.quic.stream_receive_window, and server.quic.send_window with defined
precedence, or reject those fields when iroh is selected, consistent with the
existing gso refusal behavior.
- Line 34: Update the transport configuration validation documented around
validate_idle_timeout to validate send_window independently from QUIC VarInt
fields: do not apply the VarInt maximum to send_window because its API accepts
u64, unless the narrower limit is explicitly documented as intentional.
In `@quest/m1/announce-handle.md`:
- Around line 32-34: Bound the announce request queue described by
poll_requested and requested, using a bounded queue or per-peer quota so stopped
polling cannot grow memory without limit. When capacity is exhausted, reject the
incoming Request and preserve existing handle-drop cleanup behavior. Add an
acceptance test covering requests arriving while requested() is idle.

Align the Goal with the stated audio scope.
The Goal says each publisher's encoder targets its own share. The later plan says only video consumes its grant, while audio following its grant remains out of scope. Narrow the Goal to video encoders, or include audio grant-following in this quest.

Define explicit reservation release in the JavaScript plan.
The plan lists Reservation accessors but no release path. If the allocator is shared across reloads, a closed track can remain registered and reduce grants for later tracks. Tie release() or dispose() to existing track and encoder cleanup, connection close, and add a close-then-reload test.

moq-dev/moq pull request 2854 bandwidth.rs Allocator reserve update allocate
💡 Result:
There is no public record of a pull request #2854 in the moq-dev/moq repository. The project repository (moq-dev/moq) currently has a significantly lower number of pull requests and issues [1]. Furthermore, the bandwidth.rs file within the moq-net crate focuses on bandwidth estimation, featuring a BandwidthProducer and BandwidthConsumer for handling bitrate estimates, rather than an Allocator with reserve or allocate methods [2][3]. The architecture utilizes kio for channel-based asynchronous state management [2][3]. Any reference to a PR #2854 likely pertains to a different repository or is a misidentification of the project's current development status [1][4][5].

Define how each stats sample updates the shared allocator.
The plan does not specify how the 100 ms estimatedSendRate sample recomputes grants for active reservations. Without this path, grants can remain stale, while recreating the Allocator may discard the shared reservation registry. Add a test that changes the estimate while reservations remain active.

cargo-hack --each-feature --feature-powerset official documentation semantics
💡 Result:
In cargo-hack, the --each-feature and --feature-powerset flags define different strategies for iterating over a crate's feature sets to verify compilation and testing [1][2]. --each-feature This flag performs the specified cargo command for each individual feature of the package in isolation [1][2]. It includes: - A run with no features enabled (--no-default-features) [1][3]. - A run for each individual feature, including default features [1][2]. - A run with all features enabled (--all-features), provided that no features are excluded via --exclude-features or --skip [1][3]. --feature-powerset This flag performs the command for the entire "power set" (all possible combinations) of the package's features [1][2]. This is significantly more thorough than --each-feature but grows exponentially (2^n combinations for n features) [2]. It includes: - A run with no features enabled (--no-default-features) [1][3]. - A run for all possible combinations of features [2]. - A run with all features enabled (--all-features), subject to the same conditions regarding exclusions as --each-feature [1][3]. When multiple features are present, --feature-powerset is often used with the --depth flag to limit the maximum number of features enabled in a single combination, which helps manage the exponential growth of test cases [1][2]. Both flags implicitly handle the --no-default-features and --all-features states to ensure comprehensive coverage, but they can be further controlled using --exclude-features (or --skip) to omit specific features or meta-combinations from the execution [1][3].

Cover feature combinations in the validation command.
cargo-hack --each-feature checks individual feature configurations, not combinations such as tcp+quinn. If “any subset” is required, add a bounded --feature-powerset check. Otherwise, narrow the goal to single-feature builds.

quinn 0.11.11 TransportConfig send_window receive_window stream_receive_window API documentation
💡 Result:
In the quinn 0.11.11 crate, the TransportConfig struct provides methods to configure flow control limits for the QUIC protocol [1][2]. These settings are used to manage how much data a peer may send before requiring acknowledgement, serving as an important tool for memory management and performance tuning [3][4]. The following methods are available within TransportConfig to control these windows: stream_receive_window(value: VarInt) This method sets the maximum number of bytes the peer may transmit without acknowledgement on any individual stream [3][4]. It is recommended to set this to at least the expected connection latency multiplied by the maximum desired throughput [4]. Setting this value smaller than the overall receive_window can help prevent a single stream from monopolizing receive buffers [3][4]. receive_window(value: VarInt) This method sets the maximum number of bytes the peer may transmit across all streams of a connection before becoming blocked [3][4]. Like the stream_receive_window, it should be scaled based on connection latency and desired throughput [4]. Larger values allow higher throughput for one stream while another might be blocked [4]. send_window(value: u64) This method configures the maximum number of bytes to transmit to a peer without receiving an acknowledgement [3][4]. It functions as an upper bound on memory usage when communicating with peers that issue large amounts of flow control credit [3][4]. For robust applications handling many connections, this should be set low enough to ensure memory exhaustion does not occur if every connection consumes its entire window [4]. These configurations are part of the quinn-proto layer [5][6], which governs the core QUIC state machine. You can modify these settings by calling the corresponding methods on a TransportConfig instance before using it to configure your server or client [7][4].

site:docs.rs/crate/quinn/0.11.11/source/quinn-proto/config/transport.rs send_window u64
💡 Result:
send_window in Quinn 0.11.11 is:
pub fn send_window(&mut self, value: u64) -> &mut SelfIt sets the maximum number of bytes Quinn may transmit to a peer without acknowledgment, also bounding potential send-buffer memory usage. [1]
Example:
let mut config = quinn::TransportConfig::default();
config.send_window(10 * 1024 * 1024); // 10 MiBThe corresponding connection-level method is:
pub fn set_send_window(&mut self, send_window: u64)[2]
Validate send_window separately from QUIC varints. The lockfile resolves quinn to 0.11.11. Its send_window API accepts u64, unlike the VarInt receive-window APIs. Apply the QUIC-varint limit only to the VarInt fields, or document the deliberate narrower limit for send_window.

Make quiche refusal backend-specific.
Resolved is shared across Client and Server, but the plan requires send_window to be refused only by quiche. A shared resolve() path cannot make that decision without backend context.
If the check is global, valid Quinn, noq, or iroh configurations can fail. If the check is omitted from quiche construction, the value can be silently ignored. Define the backend selection boundary and return a configuration error from the quiche client/server construction path.

Do not silently ignore server-side windows for iroh.
The existing iroh path at rs/moq-native/src/iroh.rs:163-237 builds one shared endpoint from &quic::Client. It does not receive quic::Server.
Therefore, server.quic.receive_window, server.quic.stream_receive_window, and server.quic.send_window can be parsed but not applied. This violates the apply-or-refuse requirement in Line 7.
Either pass the server configuration into the shared iroh endpoint and define precedence, or reject these server-side fields when iroh is selected.

Bound the announce request queue.
The plan makes the queue unbounded and keeps requests until the handle drops. If the application stops polling requested(), peers can continue to enqueue requests and grow process memory without a limit.
Add a bounded queue or per-peer quota. Define overflow as a rejected request. Add an acceptance test while requested() is idle.

This new quest independently owns JS producer-side announce(prefix), but quest/m1/2318-js-net-remaining-capability-gaps-vs-rs-moq-net-setup-role.md still identifies that operation as one of its two surviving gaps and has no Required section. That leaves two executable quests directing implementers to build the same API, or leaves #2318 stale after this quest finishes. Re-scope #2318 to the remaining track-end work here.
