Spec Delta: Channel Management
Change ID: add-channel-management
Capability: Channel Management
Type: NEW
ADDED Requirements
Channel Creation
Requirement: Users with permission shall create voice channels
Description: Authenticated users with channels:create permission can create new voice channels with unique names, descriptions, and access control settings.
Priority: Critical Status: Proposed
Scenarios:
Scenario: User creates public channel
Given: User is authenticated with create permission
When: User requests CreateChannel with name "general" and is_public=true
Then: New channel created with unique ID
And: User set as channel owner
And: Channel marked as public
And: All other users can join
And: CreateChannel response includes channel details
Scenario: Duplicate channel name rejected
Given: Channel "general" already exists
When: User requests CreateChannel with name "general"
Then: Request rejected with AlreadyExists error
And: User must choose different name
Scenario: Invalid channel name rejected
Given: User requests channel with empty name
When: User sends CreateChannel request
Then: Request rejected with InvalidArgument error
And: Validation fails with clear error message
Joining Channels
Requirement: Users shall join channels with permission verification
Description: Users can join public channels if authenticated. Private channels require owner approval or whitelist.
Priority: Critical Status: Proposed
Scenarios:
Scenario: User joins public channel
Given: User is authenticated
And: "general" channel is public
When: User requests JoinChannel
Then: User added to channel members
And: UserJoined event broadcast to channel
And: Response includes channel members
And: User can now send/receive voice
Scenario: User joins private channel with permission
Given: User is whitelisted for private channel
When: User requests JoinChannel
Then: User added to channel
And: Access granted
Scenario: Unauthorized user denied private channel
Given: User not whitelisted for private channel
When: User requests JoinChannel
Then: Request rejected with PermissionDenied
And: User cannot join channel
Scenario: Channel at capacity
Given: Channel has max_users=5
And: 5 users already in channel
When: 6th user joins
Then: Request rejected with ResourceExhausted error
And: Error message: "Channel is full"
Leaving Channels
Requirement: Users shall leave channels cleanly
Description: Users can leave channels at any time. Leaving stops voice streams and removes user from member list.
Priority: Critical Status: Proposed
Scenarios:
Scenario: User leaves channel
Given: User is in "general" channel
When: User requests LeaveChannel
Then: User removed from channel members
And: UserLeft event broadcast to channel
And: Voice streams stopped
And: Cleanup completed
Scenario: User disconnects (implicit leave)
Given: User connected to channel
When: User connection is lost
Then: Server detects disconnection
And: User removed from channel after timeout
And: UserLeft event broadcast
Channel Member Management
Requirement: Server shall track and provide channel member list
Description: At any time, can query active members of a channel including their presence status and mute state.
Priority: High Status: Proposed
Scenarios:
Scenario: Get channel member list
Given: Channel has 3 members
When: User requests ListMembers
Then: Response includes all 3 members
And: Each member includes: user_id, status, mute_state
And: List includes joining order (optional)
Scenario: Member presence updated
Given: User is in channel
When: User mutes microphone
Then: Server updates member mute state
And: UserMuteStateChanged event broadcast
And: Other members see user as muted
Channel Access Control
Requirement: Channels shall enforce public/private access control
Description: Public channels allow any authenticated user to join. Private channels restrict membership.
Priority: Critical Status: Proposed
Details:
- Public: Any authenticated user can join
- Private: Owner only, future whitelist support
Scenarios:
Scenario: Public channel visible and joinable
Given: Channel is marked is_public=true
When: Any authenticated user lists channels
Then: Channel appears in list
And: User can join without approval
Scenario: Private channel visibility
Given: Channel is marked is_public=false
When: Non-owner lists channels
Then: Private channel may not appear
Or: Channel appears but join is denied
Channel Capacity
Requirement: Channels shall enforce user capacity limits
Description: Channels can have maximum concurrent users limit. Default is unlimited.
Priority: High Status: Proposed
Scenarios:
Scenario: Unlimited capacity (default)
Given: Channel created with max_users=0
When: 100 users try to join
Then: All 100 accepted and added to channel
And: No capacity limit enforced
Scenario: Limited capacity enforced
Given: Channel has max_users=10
And: 9 users already in channel
When: 10th user joins - succeeds
And: 11th user attempts join
Then: Request rejected with ResourceExhausted
Channel Events
Requirement: Channel changes broadcast to members
Description: Events like user joining/leaving, channel updated, etc. broadcast to all channel members in real-time.
Priority: High Status: Proposed
Scenarios:
Scenario: User join event broadcast
Given: User A is in channel
When: User B joins channel
Then: User A receives UserJoinedEvent
And: Event includes new user info
And: Event includes timestamp
And: All channel members receive event
Scenario: Channel update event
Given: Channel members listening for events
When: Channel owner updates channel name
Then: All members receive ChannelUpdatedEvent
And: Event includes new channel state
