Adding simulated logging and refactoring subscriptions to not need to track transports
* Updated architecture.md
* In server/index.ts
- remove import of Transport
- import beginSimulatedLogging and stopSimulatedLogging
- in clientConnected()
- change argument to sessionId? instead of transport
- add call to beginSimulatedLogging
- send server and sessionId to beginSimulatedResourceUpdates and beginSimulatedLogging
- in cleanup()
- add call to stopSimulatedLogging passing sessionId
* Added server/logging.ts
- Initialize logsUpdateIntervals to Map session ID to the interval for sending logging messages to the client
- in beginSimulatedLogging()
- create an array of logging meesages, customized with the sessionId if present
- if the interval for the sessionId hasn't been set, create one, calling server.sendLoggingMessage with a random message to the client each time the interval elapses
- in stopSimulatedLogging()
- if a logging interval exists for the sessionId, clear it and remove it
* In subscriptions.ts
- remove import of Transport
- remove transports map
- in beginSimulatedResourceUpdates()
- change arguments to server and sessionId
- check for the subsUpdateInterval for the session
- remove all transport storage and interaction
- instead use the server to send the notification
- in stopSimulatedResourceUpdates()
- remove management of transports map
* In sse.ts and streamableHttp.ts
- when calling clientConnected, pass sessionId instead of transport
* In stdio.ts,
- when calling clientConnected, pass nothing instead of transport
* In subscriptions.ts
- updated inline doc
Adding resource subscriptions:
* Updated architecture.md
* In server/index.ts
- imported Transport, setSubscriptionHandlers,beginSimulatedResourceUpdates, and stopSimulatedResourceUpdates
- call setSubscriptionHandlers passing server
- in returned object,
- refactor/renamed startNotificationIntervals placehodler to clientConnected, which takes a transport argument and calls beginSimulatedResourceUpdates, passing the transport
- replaced cleanup placeholder with a function that takes an optional sessionId and calls stopSimulatedResourceUpdates, passing the sessionId
* In sse.ts, stdio.ts, and streamableHttp.ts
- when transport is connected, called clientConnect, passing transport
- when disconnecting, called cleanup, passing sessionId
* Added subscriptions.ts
- tracks subscriber session id lists by URI
- tracks transport by session id
- tracks subscription update intervals by sessionId
- in setSubscriptionHandlers
- set request handlers for SubscribeRequestSchema and UnsubscribeRequestSchema
- in beginSimulatedResourceUpdates
- starts an interval to send updates to the transport for all subscribed resources
- in stopSimulatedResourceUpdates
- removes intervals and transport for gien session id
