Is there a method of checking for cyclic dependencies between jobs in Hudson? It is simple to observe if A->B->A but if A->B->C->D->A then its almost impossible manually. Is there a plugin to do this? I think it is key functionality because such a loop between build triggers can slowly kill a server.

Check out the Downstream build view plugin. It's not a cycle detector, but it might help.
I understand the concern, but do you really have a situation where the builds do not fall into a heirarchy such that it makes no sense for build D to trigger build A?

yes I really do have that situation. I am working with a project of 2 million LOC, no testing and a dependency tree to make you weep.

Hudson has cycle detection in the regular downstream trigger setup. If you are using mechanisms outside of the downstream trigger, it's not clear how to detect the cycle.

Nice! I did not know that. Do you have a reference? I couldn't find this fact on the wiki.

Maybe it's a bug (Hudson 1.348), but I created a trivial test case (A is configured to build B, B is configured to build A) and when I kicked it off it started the *really* "continuous" build, ha ha :)

yes I had the same issue. My worry however is with more complicated loops that are difficult to see.
