Alexander Shorin commented on COUCHDB-1446:
-------------------------------------------
Just to let me not forget about, while there is special ticket about config
settings validation...
...trivial case when someone have tried to rename system database (e.g. from
_user to _my_users - why not? is this database systems or not?) makes CouchDB
instance fall with same symptoms. So I suppose config checks should not be only
"about value type", but also "about value data" for some parameters.
> 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
> Labels: config
>
> 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.
