Summary: Remove IndexFileDeleter.refresh(String)
Key: LUCENE-6786
URL: https://issues.apache.org/jira/browse/LUCENE-6786
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: Trunk, 5.4
Today IW has try/finally around places (flush, merge) that write
per-segment files and on exception uses IFD.refresh(String) to remove
any newly created but now unreferenced files.
But, since merge exceptions are now tragic, and IFD.refresh() (not
taking a segment name) will be called, doing the same thing, I think
it's safe to remove the per-segment refresh.
This makes IW a little bit simpler ... and it means at least one fewer
{{Directory.listAll}} while handling merge exceptions.
