Alex Deparvu updated SOLR-16656:
--------------------------------
Affects Version/s: 9.0
> rid parameter missing from query logs in Solr 9.x
> -------------------------------------------------
>
> Key: SOLR-16656
> URL: https://issues.apache.org/jira/browse/SOLR-16656
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 9.0
> Reporter: Alex Deparvu
> Priority: Minor
>
> I think there was a regression introduced in SOLR-15790 where the rid param
> is no longer logged correctly.
> Solr 8 logs, rid=-1 logged with final query after distributed results were
> collected:
> {noformat}
> .... INFO (qtp1482246673-23) [c:gettingstarted s:shard1 r:core_node3
> x:gettingstarted_shard1_replica_n1] o.a.s.c.S.Request
> [gettingstarted_shard1_replica_n1] webapp=/solr path=/select
> params={q=*:*&indent=true&q.op=OR&_=1675975274863} rid=-1 hits=0 status=0
> QTime=3
> {noformat}
> Solr 9 logs:
> {noformat}
> .... INFO (qtp351877391-20) [c:gettingstarted s:shard2 r:core_node7
> x:gettingstarted_shard2_replica_n4] o.a.s.c.S.Request webapp=/solr
> path=/select params={q=*:*&indent=true&q.op=OR&useParams=&_=1675975376183}
> hits=0 status=0 QTime=6
> {noformat}
> I narrowed down the issue to a problem with the SearchHandler. the part that
> determines if the rid param should be added does not match with the lifecycle
> of the ResponseBuilder.
> basically the decision to add the param is done in tagRequestWithRequestId
> [0] based on the rb.isDistrib flag which will only be computed later in
> getAndPrepShardHandler [1], so at the moment where this is supposed to be
> added, it's always false. this param will never be logged.
> Even though it's just logging, I see this as a potential regression. I think
> having this info logged is very valuable.
