Subject [jira] [Commented] (SOLR-3916) fl parsing is sensitive to newlines at the end of field names
Date Fri, 05 Oct 2012 20:58:03 GMT


Yonik Seeley commented on SOLR-3916:

bq. blaming this on xml parsing doesn't really seem productive


I'm suggesting this could be a much wider problem than just "fl", which would seem to be a
very productive line of conversation.

In the context of grabbing defaults from XML, we should consider trimming whitespace in the
process of generating those defaults (rather than later).
The only downside is if certain parameters could reasonably expect to want leading/trailing
whitespace.  If we want to support that, we could introduce a new type called <verbatim>
or something.

> As reported by giovanni.bricconi on the user list, there is a bug in "fl" parsing that
causes solr to get confused when a field name is followed by a newline character -- eg: in
a requestHandler default like...
> {noformat}
> <!-- newlines showing using "$" -->$
> <str name="fl">$
>    sku,store_slug$  
> </str>$
> {noformat}
> ...this results in solr assuming it should use function parsing to evaluate the field
name, which can cause missleading errors if the field name can't be used in a function (eg:
"can not use FieldCache on multivalued field: store_slug")
