I'm really wondering what is special about the Eclipse.org
infrastructure that causes these failures
After discussions with the owners of CI infrastructures of similar and
larger scale, the answer is that the CI system itself was not originally
designed with this type of scalability in mind. Since our CI system is
open to the world, it's exposed to the Anonymous User and all the search
engines out there that constantly fetch content (like build artifacts,
logs, and such) which use up valuable threads.
As I write this, there was one IP address in France that has been
reloading the /husdon home page continuously for the last 5 hours, and
of the last 5000 page requests, they own 2300. That consumes valuable
threads, memory and CPU cycles. I've blocked their IP.
... the current "single point of failure" is a problem. And even if it
doesn't fail, with so many jobs on the initial page it's often very
slow (categorization would help probably).
There is categorization, and some time ago, the initial page would
default to the EPP view. But someone opened up a bug, and here we are
back to square one. We could implement caches, but often committers
like seeing information the second it is updated and available.
I'm really looking forward to the HIPP initiative [1]
<http://dev.eclipse.org/mhonarc/lists/eclipse.org-committers/msg00925.html>
announced by webmaster, or whatever else can be done to improve
robustness.
So am I. There are many things we could do to improve the One Big CI
for All but in the end I'm still convinced HIPP will be a better
solution for us.
Thanh has already begun deploying HIPP for LTS and other Eclipse Working
Groups. I suspect he will begin working on the Eclipse side soon.
Thanks for your patience.
