Config settings input validation
--------------------------------
Key: COUCHDB-1446
URL: https://issues.apache.org/jira/browse/COUCHDB-1446
Project: CouchDB
Issue Type: Bug
Components: Database Core
Affects Versions: 1.2
Reporter: Jason Smith
Assignee: Jason Smith
Priority: Minor
Today I received a bug report from a user who thought CouchDB might be relaxing
and evaluate an arithmetic expression in the config. (That makes sense, since
it seems to evaluate erlang terms elsewhere.)

It would be nice for CouchDB to validate config input, particularly when bad
values permanently take it offline. (In this case, it returns 500 for all
subsequent requests.)
IMO, a good bang-for-buck is to have three basic value types:
1. String
2. Erlang tuple
3. Integer
And each setting knows what type it must be.
