Alex Boisvert updated ODE-100:
------------------------------
Attachment: GUID.java
I've been using the attached GUID class for some time now. It leverages the
JDK 5.0 GUID class and uses a thread local counter to eliminate contention.
This results in improved performance at the cost of slightly longer GUID's.
> ProcessMutex needs to release its socket more quickly
> -----------------------------------------------------
>
> Key: ODE-100
> URL: https://issues.apache.org/jira/browse/ODE-100
> Project: Ode
> Issue Type: Improvement
> Affects Versions: incubator-1
> Reporter: Dan Kearns
> Assigned To: Matthieu Riou
> Fix For: incubator-1
>
> Attachments: GUID.java
>
>
> On startup, Ode creates a GUID generator. The GUID generator uses posession
> of a socket at a particular time as a mutex to guarantee the time seed.
> However, it is using the default socket options to do this, which prevents
> rapid multiple spinup and/or restart of the processes embedding Ode as the
> socket is stuck in TIME_WAIT by the operating system.
> Fix: in ProcessMutex.java:lock(), swap:
> ss = new ServerSocket(port);
> for
> ss = new ServerSocket();
> ss.setReuseAddress(true);
> ss.bind(new InetSocketAddress(port));
