Overview ¶
Package sessionid mints terminal session IDs with a random instance segment.
Session IDs are persisted by the frontend (they become tab IDs in the tab store), so an ID must stay unique across app restarts — not just within a single Manager's lifetime. A plain incrementing counter resets to 0 on every launch, which makes a fresh process re-mint IDs an earlier run already persisted, producing two tabs that share one ID (issue #141).
Each Generator carries a random per-instance segment, so IDs minted by different processes (or different Managers) are extremely unlikely to collide even when their counters match. The ID format is "<kind>-<instance>-<n>"; the kind prefix is preserved because the frontend infers the transport from it (inferTransportFromSessionId keys off "ssh-" / "serial-" / "local-").

Types ¶
type Generator ¶
type Generator struct {
// contains filtered or unexported fields
}
Generator produces unique session IDs of the form "<kind>-<instance>-<n>". It is safe for concurrent use. Must be used by pointer (atomic counter).
func NewGenerator ¶
NewGenerator returns a Generator whose IDs are prefixed with kind (e.g. "ssh"). The random instance segment is drawn once per Generator, giving each generator an ID namespace with negligible collision risk.
