Functions ¶

func FlockExclusiveBlocking ¶

func FlockExclusiveBlocking(f *os.File) error

FlockExclusiveBlocking acquires an exclusive blocking lock on the file. This will wait until the lock is available.

func TryDaemonLock ¶

func TryDaemonLock(beadsDir string) (running bool, pid int)

TryDaemonLock attempts to acquire and immediately release the daemon lock to check if a daemon is running. Returns true if daemon is running. Falls back to PID file check for backward compatibility with pre-lock daemons.

This is a cheap probe operation that should be called before attempting RPC connections to avoid unnecessary connection timeouts.

Types ¶

type LockInfo ¶

type LockInfo struct {
	PID       int       `json:"pid"`
	ParentPID int       `json:"parent_pid,omitempty"`
	Database  string    `json:"database"`
	Version   string    `json:"version"`
	StartedAt time.Time `json:"started_at"`
}

LockInfo represents the metadata stored in the daemon.lock file

func ReadLockInfo ¶

func ReadLockInfo(beadsDir string) (*LockInfo, error)

ReadLockInfo reads and parses the daemon lock file Returns lock info if available, or error if file doesn't exist or can't be parsed
