Russell Branca created COUCHDB-2629:
---------------------------------------
Summary: Hide internal config details from other applications
Key: COUCHDB-2629
URL: https://issues.apache.org/jira/browse/COUCHDB-2629
Project: CouchDB
Issue Type: Bug
Security Level: public (Regular issues)
Components: Database Core
Reporter: Russell Branca
Throughout the code base we do things like `config:get("couch_httpd_auth",
"authentication_db", "_users")` which exposes internal details to other
applications that don't need to be aware of the particulars. This duplicates
code unnecessarily and causes problematic typos to go unnoticed like in
COUCHDB-2628.
One possible approach that I'm a fan of is to go into the application
responsible for relevant config value, and add a function to hide the details.
For instance, this is done in `cassim_metadata_cache:metadata_db`:
https://github.com/apache/couchdb-cassim/blob/windsor-merge/src/cassim_metadata_cache.erl#L58-L59
