[jira] [Updated] (LUCENE-4090) PerFieldPostingsFormat cannot use name as suffix

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

     [ https://issues.apache.org/jira/browse/LUCENE-4090?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Muir updated LUCENE-4090:
--------------------------------

    Attachment: LUCENE-4090.patch

attached is a patch for trunk.

tests pass (obviously TestBackCompat fails, its a 4.0 index and we need to fix this there too before releasing).

I changed the IDHashMap to HashMap, but i didnt implement hashCode/equals on any postingsformats yet (though, i tested this on Lucene40PostingsFormat).

I think we should do that separately? its optional and a new optimization: today they all just implement Object.equals which means it works like it did before I broke it :)

> Currently PFPF just records the name in the metadata, which matches up to the segment suffix. But this isnt enough, e.g. someone can use Pulsing(1) on one field and Pulsing(2) on another field.
> See Mark Harwood's examples struggling with this on LUCENE-4069.
