ermouth opened a new issue #1472: Creating index with "ddoc":"" makes DB read-only
URL: https://github.com/apache/couchdb/issues/1472
 
 
   <!--- Provide a general summary of the issue in the Title above -->
   
   ## Expected Behavior
   CouchDB should prevent creation of Mango index ddoc with the `_design/` _id. 
   
   ## Current Behavior
   POST-ing JSON body with `"ddoc":""` field to `/db/_index` creates a ddoc, which seems non-deletable, effectively breaks replication and makes DB non-writable (both PUT and POST fail with 500).
   
   ## Steps to Reproduce
   1. Open Fauxton
   2. Create a DB
   3. Open Mango query tab and then Mango indexes
   4. Create index with any name and `"ddoc":""` field
   
   ## Context
   I was creating Mango index editor in Couch Photon, and noticed the issue during UI tests.
   
   ## Your Environment
   <!--- Include as many relevant details about the environment you experienced the bug in -->
   * Version used: CouchDB 2.1.2 single node
   * Browser Name and version: Chrome 66
   * Operating System and version (desktop or mobile):  Xenial
