David Smiley commented on SOLR-11914:
-------------------------------------
Here's a patch.
* toMap, toMultiMap: Marked deprecated. There is some code affected in
streaming expressions: FacetStream, SqlStream, TimeSeriesStream,
GatherNodesStream. Most of the cases here looked very odd to me – a params was
being converted to a Map to a NamedList and then back to a SolrParams.
Oooookaaay. [~dpgove] could you take a look? You touched some of this before. I
removed that round-tripping, and in several places took advantage of the new
SolrParams.stream() method.
* toFilteredSolrParams: Marked deprecated. Modified the only caller in
SolrCore.preDecorateResponse to do filtering on the fly via a SolrParams inner
class impl. The notion of filtering params based on the param name does sound
useful but I think it could be added in a better way in the future as a view
and with a more flexible predicate.
* getAll: Marked deprecated. Copied these to CollectionsHandler as static
package-protected methods called "copy". I moved the test to
TestCollectionAPIs.java which is a so-so spot (none others in the package
looked better); I didn't feel like creating a new test class just for this test.
** CollectionsHandler.forEach: removed this utility method which I added a
month or two ago. Now that SolrParams implement Iterable, the desire for this
utility is low.
* toSolrParams(NamedList): Marked deprecated and moved the implementation to
NamedList as an instance method. The impl now redirects to NamedList. I left a
nocommit to remind me to adjust all callers (of which there are a ton – 40?)
but didn't want to make this patch hard to read. I added some javadocs to
toSolrParams... the null handling seems inconsistent.
* MapWriter: added some docs & comments technically unrelated to the issue
[~noble.paul] I'd appreciate a review since I know you were involved in some of
these methods.

> {{Map<String, Object> getAll(Map<String, Object> sink, Collection<String>
> params)}}
> Is only used by the CollectionsHandler, and has particular rules about how it
> handles multi-valued data that make it not very generic, and thus I think
> doesn't belong here. Furthermore the existence of this method is confusing
> in that it gives the user another choice against it use versus toMap (there
> are two overloaded variants).
> {{SolrParams toFilteredSolrParams(List<String> names)}}
> Is only called in one place, and something about it bothers me, perhaps just
> the name or that it ought to be a view maybe.
> {{static Map<String,String> toMap(NamedList params)}}
> Isn't used and I don't like it; it doesn't even involve a SolrParams! Legacy
> of 2006.
> {{static Map<String,String[]> toMultiMap(NamedList params)}}
> It doesn't even involve a SolrParams! Legacy of 2006 with some updates since.
> Used in some places. Perhaps should be moved to NamedList as an instance
> method.
