Shai Erera updated LUCENE-4575:
-------------------------------
Attachment: LUCENE-4575.patch
Patch removes commit/prepCommit(commitData) versions and modifies code that
used it (mostly tests code) to call setCommit beforehand.
I also added a CHANGES entry under back-compat section.
All tests pass. I'll wait for some review before I commit it.
> Allow IndexWriter to commit, even just commitData

> Project: Lucene - Core
> Issue Type: Improvement

> Spinoff from here

> In some cases, it is valuable to be able to commit changes to the index, even
> if the changes are just commitData. Such data is sometimes used by
> applications to register in the index some global application
> information/state.
> The proposal is:
> * Add a setCommitData() API and separate it from commit() and prepareCommit()
> (simplify their API)
> * When that API is called, flip on the dirty/changes bit, so that this gets
> committed even if no other changes were made to the index.
> I will work on a patch a post.
