logd

logd is the centralized in-memory logging service for EriX.

It accepts structured append requests over IPC, stores records in a bounded ring, and serves cursor-based reads for diagnostics and validation flows.

Responsibilities

  • validate structured log append requests
  • assign monotonic record ids and timestamps
  • retain recent records in a fixed-size ring buffer
  • return deterministic read results through cursor traversal
  • mirror accepted records to console services when enabled

logd is not responsible for persistent storage or external log shipping.

IPC Surface

Implemented operations (see lib-ipc for wire structs/IDs):

  • IPC_PHASE1_LOGD_OP_APPEND
  • IPC_PHASE1_LOGD_OP_READ

Append responses include assigned record_id and timestamp. Read responses include deterministic cursor progression and NOT_FOUND when exhausted.

Runtime feature model

  • logd-runtime: core daemon behavior
  • logd-runtime-phase1-logging: base logging contract enablement
  • logd-runtime-phase1-time: timestamp source from timed
  • logd-runtime-phase3-serial: mirror appends to seriald
  • logd-runtime-phase3-framebuffer: mirror appends to both seriald and fbcond

Integration aliases (logd-integration-*) map to the same runtime behavior, with optional force-fail test injection in dedicated test modes.
