Uwe Schindler updated LUCENE-3606: ---------------------------------- Attachment: LUCENE-3606-deprecations3x.patch Final patch including changes.txt. Will commit this now. > Make IndexReader really read-only in Lucene 4.0 > ----------------------------------------------- > > Key: LUCENE-3606 > URL: https://issues.apache.org/jira/browse/LUCENE-3606 > Project: Lucene - Java > Issue Type: Task > Components: core/index > Affects Versions: 4.0 > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Fix For: 4.0 > > Attachments: LUCENE-3606-deprecations3x.patch, > LUCENE-3606-deprecations3x.patch, LUCENE-3606-deprecations3x.patch, > LUCENE-3606-hideMethodAgain.patch, LUCENE-3606.patch > > > As we change API completely in Lucene 4.0 we are also free to remove > read-write access and commits from IndexReader. This code is so hairy and > buggy (as investigated by Robert and Mike today) when you work on > SegmentReader level but forget to flush in the DirectoryReader, so its better > to really make IndexReaders readonly. > Currently with IndexReader you can do things like: > - delete/undelete Documents -> Can be done by with IndexWriter, too (using > deleteByQuery) > - change norms -> this is a bad idea in general, but when we remove norms at > all and replace by DocValues this is obsolete already. Changing DocValues > should also be done using IndexWriter in trunk (once it is ready) -- This message is automatically generated by JIRA.
