endpoint

Documentation

Overview

Package endpoint finds the daemon a config's clients talk to: the socket the config names, or, when another daemon already serves the same store on another socket, that one. Every client resolves through it before it connects (the TUI, --call, --print-endpoint), so two configs that share a store attach to one daemon instead of spawning into its lease.

Functions

func Holder

func Holder(ctx context.Context, storePath, fallback string) string

Holder is the address of the daemon serving the store at storePath, as its lease-info names it and a probe confirms, or fallback.

func Resolve

func Resolve(ctx context.Context, cfg *config.Config) (addr, configured string, err error)

Resolve is the address a client of cfg connects to, and the one cfg names (where a spawned daemon binds). The store's lease-info is believed only when the address it names answers as this store's daemon (store_id) and as the process that wrote the record (instance); a missing, stale or mismatched record leaves the configured socket.
