Amrit Sarkar commented on SOLR-18602:
-------------------------------------
Attached a failing test:
{{DeleteReplicaTest.deleteReplicaByCountFollowsAliases}} deletes by {{count}}
through an alias with {{followAliases=true}}, once for one shard and once
across all shards. On main it fails with {{Could not find collection :
deleteByCountAliasName}}.
The fix resolves the alias in {{deleteReplicaBasedOnCount}} the same way the
replica-name path already does. PR coming shortly.
> DELETEREPLICA with count ignores followAliases

> {{DELETEREPLICA}} by {{count}} fails when {{collection}} is an alias, even
> with {{followAliases=true}}:
> {noformat}
> /admin/collections?action=DELETEREPLICA&collection=myAlias&shard=shard1&count=1&followAliases=true
> {noformat}
> returns {{Could not find collection : myAlias}}.
> {{DeleteReplicaCmd.call}} routes count requests to
> {{deleteReplicaBasedOnCount}} before it reads {{followAliases}}, and
> {{deleteReplicaBasedOnCount}} looks up {{collection}} as given. Deleting by
> replica name ({{replica=...}}) resolves the alias and works.
> Expected: resolve the alias in the count path too, with or without {{shard}}.
> Found while writing tests for SOLR-18589.
