execution

This package provides a kind of framework to run a few of high level goroutine which are locally called processes and provide it's graceful shutdown by context cancellation.

If your process object has a methods to satisfy execution.ManagedProcess interface. It could be taken on the control with execution.ExecutionManager by calling it's TakeOnControll method.

All of these processes will be executed in a parallel goroutines by the ExecuteProcesses method of execution.ExecutionManager call. If on of these goroutines will return, or if an application will get a configured signal from OS (SIGINT or SIGTERM by default) the common context will be cancelled. ExecuteProcesses method will return when all of processes under control returns from it's Run method.

You can provide a configuration of type execution.ExecutionManagerConfig to setup a set of signals to start a procedure of graceful shutdown. Also external logger could be provided to display a log of execution state changing. This logger should satisfy an execution.Logger interface.

Example of using this framework to manage the execution of two web servers available here.
