- client_session_interaction_sequence using inotify - activity_watchdog_session_lifecycle handling stale sessions - sequence_early_disconnect_race handling any race during session startup GIT_ORIGIN_SPP_REV_ID: a98614e80bc35fa95c4c63c7936e159f61057b9b

Increase message-passing notify limits to allow server->client non-blocking notifications as described in the Notify-based acquire design. GIT_ORIGIN_SPP_REV_ID: 71ef3ab5e83849c989f3b95747a75c2029213f66

Replace per-client AcquireRequest delivery via client sender Send() with server-side IServerConnection::Notify(). This avoids reply-blocked MsgSend/writev on a shared client engine thread and prevents cross-client head-of-line blocking. GIT_ORIGIN_SPP_REV_ID: 36526ff0ea5d08488960a7a22418fb1bb810bd99

Register an IClientConnection NotifyCallback and process kAcquireRequest notifications by switching buffers and replying with kAcquireResponse. This is the client-side Notify-based acquire design. GIT_ORIGIN_SPP_REV_ID: 735123e22884507b8c9ab85f0833ae28a5b7865e

Track per-session state and avoid sending additional kAcquireRequest notifications while a previous request is still outstanding. Clear stored server connection pointers on disconnect to avoid stale references. GIT_ORIGIN_SPP_REV_ID: 5cafcea87edf14043e3ebe1a85a11d90dde75e75

Track per-session acquire deadlines and miss counts and tear down sessions that do not reply with kAcquireResponse within the configured deadline for N consecutive misses. The watchdog runs off the existing mp_worker periodic tick to avoid per-session OS timers. GIT_ORIGIN_SPP_REV_ID: 84bb226ff8e017049e94740294234de06310a7f6

- Remove the unused per-client IClientFactory dependency from the message passing server. - NotifyAcquireRequestFailed() is no longer used after the Notify based acquire refactoring. GIT_ORIGIN_SPP_REV_ID: 48aeeefb01510f1d9599c339796e11a13a422e30

- If a client disconnects while OnConnectRequest is creating a session outside mutex_, disconnect_callback previously could not clear connection_ because the PID was not yet in pid_session_map_. - This could lead to storing &connection after the framework already tore the connection down. - Track early disconnects per PID and refuse to store a connection pointer when a disconnect was observed. GIT_ORIGIN_SPP_REV_ID: 879672cc335db046848fe15571a0672c1616ee0a

Avoid relying on implementation-defined steady_clock epochs and make the deadline not set state explicit. GIT_ORIGIN_SPP_REV_ID: 5f3da32556784c74bde3d52de069446907633c3d

Add a unit test that verifies the acquire watchdog. After an initial missed deadline, a late but valid AcquireResponse must reset the miss counter so the client is only torn down after the configured number of subsequent misses. GIT_ORIGIN_SPP_REV_ID: 4667d0ea0811633d2fe10b57e1293aa0810be185

- test ensuring that OnAcquireResponse ignores messages coming from a stale server connection after a client reconnects with the same PID. GIT_ORIGIN_SPP_REV_ID: 927c11ac7b4fd20cbd8e91930b25b4505f08788d

- Now that datarouter does not connect to client's IServer, the disconnect callback is never called. - Addds RequestInternatShutdown when the state callback kStopped is received. GIT_ORIGIN_SPP_REV_ID: fd475ea00de2bc097c8ae6f128344bf8641bddc1

GIT_ORIGIN_SPP_REV_ID: 7d681ddd0dae1e8b63ace4e3fccab211a2773380

- The server already uses IServerConnection::Notify() on the existing single channel to send acquire requests. The client's second channel is redundant. GIT_ORIGIN_SPP_REV_ID: e0802ae92ba9090de244ac7ef14872cb3432c213

- Treat ENOBUFS as a transient error and let the watchdog handle the unresponsive client - this mitigates session disconnection if the client is slow usually during startups GIT_ORIGIN_SPP_REV_ID: 35579555a589dfeab63587b6c3cac7640984963d

- release the global mutex before calling connection->Notify() - Removed NotifyAcquireRequestWhileLocked() as it is no longer needed. GIT_ORIGIN_SPP_REV_ID: 0546d81a5efcccaabeb0fc843acc102d57f7ea84
