[jira] [Updated] (COUCHDB-904) No method to detect view server VM version

["Randall Leeds (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/COUCHDB-904?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Randall Leeds updated COUCHDB-904:
----------------------------------

    Fix Version/s: 2.0

I'm going to say this is a good one for 2.0. Breaks protocol, but also a major version release is a good time to install these sorts of forward-compatibility features.

> There's currently no way to tell what version of the view server is being used. Ie, the JS VM (Or Python, or Ruby, etc) that is being used. Just occurred to me it could be useful for debugging things that work one place and not another.
> A proposed simple fix would be to have the view server protocol dictate that when a server boots up it spits out a line like:
> {"version": OPAQUE_STRING} that gets stored in a view_server_versions section in the config or some such.
