* agent: release JobTerminate handler when job ends before registration
JobRequest registered the job's JobTerminate handler after AssignJob
returned, so an ended UpdateJobStatus or worker disconnect handled in
between deregistered nothing and the handler leaked. AssignJob also sent
the assignment before recording the job as running, so an immediate
ended update was dropped.
Record the job before sending the assignment, and after registering the
handler recheck under h.mu that the job is still running and its worker
still registered, deregistering otherwise.
Fixes#4901
* replace utils.CloneProto with proto.CloneOf
* agent: wait on worker readiness and poll for released handlers in test
* service: enforce metadata size limit in CreateRoom, bump default to 512 KiB
CreateRoom previously accepted any metadata size; only UpdateRoomMetadata
rejected oversized payloads. Mirror the same CheckMetadataSize check at
the CreateRoom API boundary so both entrypoints are bounded.
Default MaxMetadataSize moves from 64000 to 512 * 1024 to match the
practical needs of customers using room metadata for richer state. The
limit remains configurable via the existing limits.max_metadata_size knob.
* service: split room vs. participant metadata limit, enforce on join + agent dispatch
LimitConfig.MaxMetadataSize was shared between room metadata and
participant metadata. Last commit's bump to 512 KiB lifted both ceilings;
this restores the participant ceiling to 64 KB and introduces a separate
MaxRoomMetadataSize (default 512 KiB) for room metadata.
Additional enforcement:
- RoomManager.StartSession rejects joins whose JWT-grants metadata or
attributes exceed the participant/attributes limits. The check was
missing entirely from this path.
- AgentDispatchService.CreateDispatch and the embedded
CreateRoomRequest.Agents path now validate metadata and attributes
against the common 64 KB ceilings (previously unbounded).
NewAgentDispatchService gains a LimitConfig parameter; the two wire_gen
callsites are updated.
* service: collapse metadata size limit to single 512 KiB knob
Reverts the LimitConfig split introduced in the previous commit:
MaxRoomMetadataSize, CheckRoomMetadataSize, and the max_room_metadata_size
yaml key are removed. MaxMetadataSize moves back to 512 * 1024 and gates
all metadata uniformly — room (CreateRoom, UpdateRoomMetadata), participant
(UpdateParticipant, signal UpdateMetadata, JWT grants on join), and agent
dispatch (CreateDispatch + embedded RoomAgentDispatch).
MaxAttributesSize stays at 64 KB and continues to gate participant and
agent-dispatch attributes separately.
Test cases consolidated under the single knob.
* kb -> kib
* agent: thread simulation flag from dispatch to job
Reads simulation from AgentDispatch / RoomAgentDispatch and copies it
onto Job in agent.LaunchJob and the inline room-agent path so workers
see the flag.
Stacked on top of livekit/protocol#1629.
* agent: replace simulation bool with attributes map
Threads the renamed attributes map (was bool simulation) from dispatch
to job and bumps the protocol pseudo-version.
* deps
This allows listing, adding and deleting agent dispatches on an existing room. Requests go to a new AgentDispatchService, which sends them over RPC to the rtc.Room via the RoomManager. The rtc.Room then does agent job management using RPCs to the agent service.
