Subject [jira] [Commented] (COUCHDB-1362) couchjs doesn't clean out global namespace between views calls
Date Mon, 12 Dec 2011 22:15:30 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13167862#comment-13167862
] 

Randall Leeds commented on COUCHDB-1362:
----------------------------------------

Would sealing/freezing the global object be sufficient? Users could probably still hang stuff
off attributes of the global object, such as passing information between views by adding it
as a property of the log() function, but at that point users should _know_ they're being tricky
and they might get punched.

With SM1.8.5 we could deep freeze the object, though I'd have to double check that it wouldn't
break any functionality.

> Sometimes a view can access the functions that were defined in a previous view.  This
can lead a developer to think that function sharing has been implemented, but it's not reliable
behaviour.  It would be better if the global namespace were cleared between map/reduce runs
so that it's clear that there is no reliable way to share functions between views.
