Subject [jira] [Created] (COUCHDB-1446) Config settings input validation
Date Tue, 20 Mar 2012 04:15:57 GMT
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.)

https://getsatisfaction.com/iriscouch/topics/my_couchdb_is_broken_after_putting_a_badarg_for_a_configuration_value

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.
