There's something terrible about this query search that causes Query::Node::toString to go crazy. I'll leave that for later, and stop trunk from crashing for now.

-- SvenDowideit - 17 Mar 2011

The only error here is in the size of the query. perldiag says:

Deep recursion on subroutine "%s"
(W recursion) This subroutine has called itself (directly or indirectly) 100 times more than it has returned. This probably indicates an infinite recursion,

so if you evaluate a tree of more than 100 levels deep recursively, it will barf - and because we have more than 100 extensions, which are expanded as a tail recursive OR tree, that recursion depth is hit. it can equally be worked around using no warnings 'recursion' around the toString method in Node.pm.

I disabled the recursion warning on that function.

-- CrawfordCurrie - 06 Apr 2011

Shouldn't this just be closed? The bug does not appear in released code does it?

-- GeorgeClark - 11 Apr 2011

This should not have been closed. It should have been a release blocker for 1.1.3.

I have a failing 1.1.3 installation now because of this bug

Why was the fix only checked into trunk?

The same topic & query ( Tasks/ReleaseBlocker worked fine on 1.1.3 throughout the beta. The problem was never observed on 1.1.3. It still works fine on 1.1.3.

In my actual case someone had written a query with more than 100 nodes (built from a regex search within the search string of a query search).

So the fix is relevant but will only be seen by very long queries and only produces a warning in the log. Search still works without fix. Now fixed so people have a cleaner log when upgrading to 1.1.4.

This is not completely fixed - the topic ComponentSearch is a nested search that triggers the recursion errors in OP_or and Node.

It appears that the no warnings 'recursion' is needed around the recursive calls., especially the AND, OR, and the evaluatesToConstant routine.
