I looked at the test that failed here -
TestFreeTextSuggester.testLookupsDuringReBuild and for the life of it
I can't see how it's even supposed to work. What it seems to be
testing is a concurrent rebuild of the suggester while suggestions are
still being served. But the code inside FreeTextSuggester has no means
whatsoever to make this happen - count and fst fields are just updated
without any synchronization or even caution about concurrency. In
fact, I don't see anything in the Lookup interface that would suggest
it's safe to rebuild a suggester concurrently:
/**
* Builds up a new internal {@link Lookup} representation based on the
given {@link
* InputIterator}. The implementation might re-sort the data internally.
*/
public abstract void build(InputIterator inputIterator) throws IOException;
Is this something that was added in between? Is this even enforced
anywhere? Seems like a buggy test that verifies something that isn't
guaranteed.
