Shai Erera updated LUCENE-1720:
-------------------------------
Attachment: LUCENE-1720.patch
Added patch contains, above all previous things:
* Changes to FitlerIndexReader to better support extensions.
* Changes in TimeLimitingIndexReader based on the previous bullet.
* Changes to TestIndexReader to better support extensions.
* TestFilterIndexReader now extends TestIndexReader.
* TestTimeLimitingIndexReader was added few test methods.
Although some of the changes can be viewed as belonging to a separate issue, I
think they are not very big and fit nicely here. It allows testing the new
TimeLimitingIndexReader which is important.
Mark, the only thing that remains is to convert
TimeLimitingIndexReaderBenchmark to a benchmark algorithm/task. Would you mind
taking a stab at this? If not, I'll try to get to it later this week (perhaps
in a day or two).

> 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.
