Subject [jira] [Commented] (LUCENE-5618) DocValues updates send wrong fieldinfos to codec producers
Date Tue, 22 Apr 2014 19:06:15 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-5618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13977216#comment-13977216

Shai Erera commented on LUCENE-5618:
------------------------------------

OK I'll take a look at passing all FIs. I agree the current check is important. If we pass
only the set of FIs the Codec sees though, I think we should also check that the Codec read
all the fields the FIS say it should read (currently it only checks that all the fields it
reads are in the FI, but not if there are "missing" fields). But if we pass all FIS, that's
not a problem.

> See the example there, docvalues readers get a fieldinfos, but it doesn't contain the
correct ones, so they have invalid field numbers at read time.
> This should really be fixed. Maybe a simple solution is to not write "batches" of fields
in updates but just have only one field per gen? 
> This removes many-many relationships and would make things easy to understand.
