hongen is a simple watchdog for Windows.
Usage:
$ hongen <command-line>
hongen will start the command specified in the command line and will keep the child process running forever.
The nice thing about it is that it will create a Job Object
for the child process and all its decendents. When the child process exits (crashes), hongen will close the job
object (subsequently causing all the decendents to be killed as well) and then respawn the child.
We use hongen as part of anode as the root of our worker roles in Azure, which spawn multiple
child processes.
$ hongen %ProgramFiles(x86)%\nodejs\node.exe c:\server.js
Will spawn the node program c:\server.js and will keep it alive forever.
Note that you can use environment variable expansions (e.g. %ProgramFiles(x86)% resolves to where the 32-bit
program files are).
$ hongen %COMSPEC% /c c:\some\batch.cmd
Note that you should use %COMSPEC% /C (resolves to where cmd.exe is) if you want to run a batch file.
