David Smiley updated SOLR-8460:
-------------------------------
Attachment: SOLR_8460.patch
See attached patch.
This fix is for ARHB.ListBasedTokenStream to take an AttributeSource in the
constructor to serve as the source of the attribute impls which are added in
the constructor in a loop. This adds the attributes as side effect as well.
There is then no reason to copy the defined attributes in incrementToken
because it's done in the constructor.
I'll commit in a couple days pending feedback.
> /analysis/field doesn't always handle custom attributes correctly

> I've got some custom analysis Attribute implementations in my analysis chain
> with some other custom analysis components. I found that Solr's Analysis
> utility screen, powered by /field/analysis (FieldAnalysisRequestHandler
> subclassing AnalysisRequestHandlerBase) gave me exceptions for two reasons,
> both having to do with AnalysisRequestHandlerBase.ListBasedTokenStream:
> * Custom implementations of standard Attributes (e.g. FlagsAttribute) would
> trigger an exception.
> * Calling getAttribute (instead of addAttribute) in a TokenFilter constructor
> wouldn't find an attribute added by the input TokenStream.
