Simon Willnauer updated LUCENE-2831:
------------------------------------
Attachment: LUCENE-2831.patch
Attaching my current state. There is still one testcase failing in solr land
that violates the hierarchy (TestFunctionQuery) or rather the contract between
Query#weight() and Weight#scorer() in not using the correct leaf readers etc.
I added 2 structs CompositeContext and AtomicContext which made it somewhat
simpler IMO. Yet, I try to fix the solr problems as far as i can - if that is
not possible without major changes i will remove the assert in TermWeight since
all tests pass without it though.
if someone finds the time to look at the Context impls - comments very welcome!

> Spinoff from LUCENE-2694 - instead of passing a reader into Weight#scorer(IR,
> boolean, boolean) we should / could revise the API and pass in a struct that
> has parent reader, sub reader, ord of that sub. The ord mapping plus the
> context with its parent would make several issues way easier. See
> LUCENE-2694, LUCENE-2348 and LUCENE-2829 to name some.
