Subject [jira] Created: (COUCHDB-377) allow native view servers
Date Sun, 07 Jun 2009 04:24:07 GMT
allow native view servers

                 Key: COUCHDB-377
             Project: CouchDB
          Issue Type: Improvement
            Reporter: Mark Hammond
         Attachments: native_query_servers.patch

There has been some discussion on IRC etc about how to support 'native' view servers, such
as 'erlview' in a generic way.  Currently using erlview requires you to modify couch.

I'm attaching a patch as a first attempt at supporting this.  In summary, the patch now looks
up a new 'native_query_servers' config file section for a list of view_server names with a
{Module, Func, Args} style string specifying the entry-point of the view server.  The code
now passes an additional atom around indicating if the PID is 'native' or 'external', and
map_docs takes advantage of this to avoid the json step.  This patch allows erlview to work
for me, but in theory any erlang code could be used here.

I'm very new at erlang - please let me know if I should make stylistic or other changes, or
indeed if I should take a different approach completely.
