Mark Harwood commented on LUCENE-1720:
--------------------------------------
re points 1,2,3 - yep, will change.
re the question - yes, TimeoutThread should call the existing
"resetFirstAnticipatedFailure()" method to advance timeout monitoring
immediately to the next candidate - it currently requires the first bad Thread
to call stop() before monitoring is advanced to spot the next bad thread.
I think a useful safety measure is to manage clients that don't call stop()
(e.g. forgetting to code a "finally...stop") but this is likely to add
complexity to ActivityTimeMonitor so I want to get a basic version solid first
before thinking too much about this.

> Project: Lucene - Java
> Issue Type: New Feature
> Components: Index
> Reporter: Mark Harwood
> Assignee: Mark Harwood
> Priority: Minor
> Attachments: ActivityTimedOutException.java,
> ActivityTimeMonitor.java, TestTimeLimitedIndexReader.java,
> TimeLimitedIndexReader.java

> An alternative to TimeLimitedCollector that has the following advantages:
> 1) Any reader activity can be time-limited rather than just single searches
> e.g. the document retrieve phase.
> 2) Times out faster (i.e. runaway queries such as fuzzies detected quickly
> before last "collect" stage of query processing)
> Uses new utility timeout class that is independent of IndexReader.
> Initial contribution includes a performance test class but not had time as
> yet to work up a formal Junit test.
> TimeLimitedIndexReader is coded as JDK1.5 but can easily be undone.
