Subject [jira] Commented: (LUCENE-2651) Add support for MMapDirectory's unmap in Apache Harmony
Date Sat, 18 Sep 2010 15:03:33 GMT


Robert Muir commented on LUCENE-2651:

I tested the patch, i don't think we should add this yet.

at a basic level, it works. for example TestIndexFileDeleter.testDeleteLeftoverFiles will
pass, where it fails without it.
but other tests will fail, such as TestIndexReaderReopen.

its worth mentioning that mmapdirectory didnt even work at all with 5.0M14, and only started
working with 5.0M15 (released a few days ago).
before the latest release it just wrote corrupted indexes.

so it would be better for now to not supply a cleaner for harmony, and let it default to SimpleFSDirectory

> The setUseUnmap does not work on Apache Harmony, this patch adds support for it. It also
fixes a small problem, that unmapping a clone may cause a sigsegv.
