Agenda

Add or comment on agenda items here, just prefix the item with your name so we can identify you on the call:

• 2.x release?

• 3.0.0
  • M2
  • M3
  • RC

• [henrik] I got two bugs submitted with patches,(https://bugs.eclipse.org/bugs/show_bug.cgi?id=371312 & https://bugs.eclipse.org/bugs/show_bug.cgi?id=371313) but I haven't had any reaction on them. Am I missing some step in the submission process or are people just busy with other tasks?

• [henrik] we should clarify system requirements
  • Java version ?
  • Capabilities of container ? (Java EE 5 web container?)

• [henrik] performance work
  • I have seen high load causing lock congestion in java.text.MessageFormat / java.util.Concurrency (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=372679) I have tried to look at the code but I cannot seem to find a nice way around it. first of it is stapler features, secondly the messageformat class seems to always instantiate the sub formats, so no way to cache them. Any ideas?

• • When hudson is stressed it gets really slow at serving files e.g. downloading a artifact is 5-10 times slower than loading in apache/scp. How do we best debug this, so that core developers have something to go on, and how can we improve the situation ? (can we siwtch to nio for master/slave communication? or use better streaming format?)
  • I suggest that many of the resources which does not change often, is written to disc and served from there instead of being processed/calculated on every request. I suggest we create a "component" (service) where plugins can register a url to match,a file to serve and a expiration time. what do you think of this idea.

• Infrastructure Machines
  • [henrik] Room for sonar install (we really need this)?
