iilyak opened a new pull request #762: Use fully qualified call to allow code upgrade
URL: https://github.com/apache/couchdb/pull/762
 
 
   ## Overview
   
   `rexi_monitor:wait_monitor/1` function is called recursively. This means
   that hot code upgrade will not work when we are inside that
   function. Use fully qualified call to allow the update of a module.
   
   ## Testing recommendations
   
   1. Add `-export([wait_monitors/1]).`
   2. Run following snippet
       ```
       Self = self(), spawn(fun() -> rexi_monitor:wait_monitors(Self) end).
       code:soft_purge(rexi_monitor).
       ```
   3. Without this change the test ^^ would always return false.
   ## Checklist
   
   - [x] Code is written and works correctly;
   - [ ] Changes are covered by tests;
   - [ ] Documentation reflects the changes;
