Michael McCandless updated LUCENE-1654: --------------------------------------- Attachment: LUCENE-1654.patch OK I added per-segment private storage of diagnostics within IW. It records the current Lucene version plus OS & Java version details, and the reason for the segment (flush or merge) as a Map<String, String>. I also changed the commitUserData to be a Map<String,String> too. This API has not yet been released so we are free to change it. CheckIndex now prints both the commit level and per-segment level maps. I added Constants.LUCENE_VERSION to record the current version. I try to look up the impl version from the manifest and use that, else I fallback to a String constant (now 2.9-dev). I also added a unit test that asserts this value matches what's in common-build.xml. When I commit I'll update ReleaseTodo on the wiki to remember to update this value. I plan to commit in a day or two. > Include diagnostics per-segment when writing a new segment > ---------------------------------------------------------- > > Key: LUCENE-1654 > URL: https://issues.apache.org/jira/browse/LUCENE-1654 > Project: Lucene - Java > Issue Type: Improvement > Reporter: Michael McCandless > Assignee: Michael McCandless > Fix For: 2.9 > > Attachments: LUCENE-1654.patch > > > It would be very helpful if each segment in an index included > diagnostic information, such as the current version of Lucene. > EG, in LUCENE-1474 this would be very helpful to see if certain > segments were written under 2.4.0. > We can start with just the current version. > We could also consider making this extensible, so you could provide > your own arbitrary diagnostics, but SegmentInfo/s is not public so I > think such an API would be "one-way" in that you'd have to use > CheckIndex to check on it later.
