Hi,
The next step for JEP 102, Process API Updates is to provide an API to
enumerate the hierarchy of processes and to be able to terminate a
process tree.
This draft javadoc <http://bussund0416/%7Erriggs/pdoc/>update [1] includes:
- ProcessHandle class to provide handles to processes, their children,
parent, process id and liveness
- Process extends ProcessHandle and inherits the new behaviors
- Method destroyProcessTree() terminates a process tree
Additional functions related to termination and information about processes
will be added in a later update.
Comments appreciated, Roger
I still have a not-great feeling about the lack of atomicity inherent in
these operations. At least when you're dealing with direct child
processes (on UNIX-likes), there is some measure of control, in that a
process is zombified until reaped by wait() and friends.
Also I have a much higher level of concern about destroyProcessTree(),
which I don't think has any place in this API. Control of any process
belongs solely with their parent (or PID 1), in my opinion.
Those concerns aside, what about making the allChildren() and
allProcesses() methods lazy in some way?
