Question

I’ve been working with Jetty’s Continuations API and just figured out a very frustrating bug (* at least I think this was the reason*).

If I had read more closely, I would have seen this:

The timeout should be set before the suspend, by a call to
continuation.setTimeout(long); if no timeout is set, then the default
period is used.

So in my code, I was simply suspending a continuation without setting a timeout. When I read this in the documentation…

A timeout of <=0 means the continuation will never expire.

… and then tried setting the timeout to something negative, things started working (* at least it seems so *).

Unfortunately, I haven’t been able to figure out what the “default period” is for a timeout. Where can I find this out?

Answer 1

I guess I figured this out while stepping through the debugger… the default time period is 30 seconds. I found the source code…

http://www.jarvana.com/jarvana/view/org/eclipse/jetty/aggregate/jetty-all/8.0.4.v20111024/jetty-all-8.0.4.v20111024-sources.jar!/org/eclipse/jetty/continuation/FauxContinuation.java?format=ok

… and it seems like this FauxContinuation implementation of a Continuation was being constructed and the timeout is initialized to 30 seconds.
