Types

type MonitoredProc

type MonitoredProc struct {
	// contains filtered or unexported fields
}

func (*MonitoredProc) Monitor

func (p *MonitoredProc) Monitor(logName string)

func (*MonitoredProc) Stop

func (p *MonitoredProc) Stop(mon bool) error

type ProcManager

type ProcManager struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

func New

func New(executor exec.Executor) *ProcManager

Create a new proc manager

func (*ProcManager) Run

func (p *ProcManager) Run(logName, command string, args ...string) error

Start a child process and wait for its completion

func (*ProcManager) RunWithCombinedOutput

func (p *ProcManager) RunWithCombinedOutput(logName, command string, args ...string) (string, error)

Start a child process and wait for its completion

func (*ProcManager) RunWithOutput

func (p *ProcManager) RunWithOutput(logName, command string, args ...string) (string, error)

Start a child process and wait for its completion

func (*ProcManager) Shutdown

func (p *ProcManager) Shutdown() error

func (*ProcManager) Start

func (p *ProcManager) Start(name, command, procSearchPattern string, policy ProcStartPolicy, args ...string) (*MonitoredProc, error)

Start the given process with the provided arguments. Handling of any matching existing process will be in accordance with the given ProcStartPolicy. The search pattern will be used to search through the cmdline args of existing processes to find any matching existing process. Therefore, it should be a regex pattern that can uniquely identify the process (e.g., --id=1)

type ProcStartPolicy

type ProcStartPolicy int
