[jira] [Updated] (LUCENE-3576) TestBackwardsCompatibility needs terms with U+E000 to U+FFFF

["Robert Muir (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-3576?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Muir updated LUCENE-3576:
--------------------------------

    Attachment: index.36.surrogates.zip
                LUCENE-3576_trunk_test.patch
                LUCENE-3576_3x_createIndex.patch

Here's the patch to make the index from 3.x's testbackwards, and a simple test for trunk that fails. I also attached the zip.

I'll work on fixing the preflex codec's termvectorsreader/writer now.

> we changed sort order in 4.0, and have sophisticated backwards compatibility (e.g. surrogates dance),
> but we don't test this at all in TestBackwardsCompatibility.
> for example, nothing handles this case for term vectors...
