Subject [jira] Commented: (SOLR-414) Coherent plugin initialization strategy
Date Wed, 21 Nov 2007 21:19:43 GMT


Ryan McKinley commented on SOLR-414:

> it hadn't occurred to be that ResourceLoader could be a super class of Config ... i was
assuming it would just be an object SolrConfig (or the SolrCore) held on to, and we'd deprecate
those methods in Config.  is there an advantage i'm not thinking of to having it be superclass?

The only reason it is a super class is for easy API compatibility. Perhaps a better way is
to have an independent ResourceLoader and add @deprecated getters to
public String getConfigDir()
  return loader.getConfigDir()

> In theory "ResourceLoader" can be a very constrained interface for the plugins themselves
that has no Solr dependencies...

I like that.  I'll put the 'ResourceLoader' class in o.a.s.util

> We currently load many plugins with a Map or NamedList -- since SOLR-215, the current
core is not available through SolrCore.getSolrCore() and may need to be used for initialization.

This patch offers a solution to keep existing 1.2 APIs, and allow access to the SolrConfig
and SolrCore though ThreadLocal.  This should be removed in a future release.
