Room.configuration accepted arbitrary JSON without validation, allowing unsafe
or malformed payloads to be stored and creating a security risk. Define a
Pydantic schema to enforce structure and constraints, and add validation
at the serializer level to reject invalid inputs.
Introduce new method on lobby system to clear lobby cache for specific
room and participant combinations.
Enables targeted cleanup of lobby state when participants leave or are
removed, improving cache management and preventing stale lobby entries.
Refactor lobby system to use consistent UUID v4 across lobby
registration and LiveKit token participant identity instead of
generating separate UUIDs.
Maintains synchronized identifiers between lobby cache and LiveKit
participants, simplifying future participant removal operations by
using the same UUID reference across both systems.
Extend LiveKit token creation utility with additional room configuration
and user role parameters to properly adapt room_admin grants and
publish sources based on permission levels.
This creates technical debt in utility function design that should be
refactored into proper service architecture for token
generation operations in future iterations.
Move from lobby service to utils for reuse across services. Method is
generic enough for utility status. Future: create dedicated LiveKit
service to encapsulate all LiveKit-related utilities.
Create dedicated utility function for livekit API client initialization.
Centralizes configuration logic including custom session handling for SSL
verification. Improves code reuse across backend components that interact
with LiveKit.
Improves sendData reliability by preventing execution when the room
doesn’t exist.
This change addresses errors in staging and production where waiting
participants arrive before the room owner creates the room.
In remote environments, the LiveKit Python SDK doesn’t return a clean
Twirp error when the room is missing; instead of a proper "server unknown"
response, it raises a ContentTypeError, as if the LiveKit server weren’t
responding with a JSON payload, even though the code specifies otherwise.
While the issue cannot be reproduced locally,
this should help mitigate production errors.
Part of a broader effort to enhance data transmission reliability.
Importantly, a participant requesting entry to a room before the owner
arrives should not be considered an exception.
Invert operation sequence to first notify people in room before setting
participant in cache. Fixes infinite loop issue caused by 3s cache timeout
for waiting participants when requests take too long. Problem only occurred
when notifications were delayed, as faster notification delivery masked the
race condition.
