Randall Leeds resolved COUCHDB-103.
-----------------------------------
Resolution: Not A Problem
I'm not sure if my understanding of the problem is 100% accurate, but it seems
from this ticket like this was a problem in spidermonkey 1.8, with no
workaround, but it's fixed in 1.9. If we can do what we want to in 1.9 I think
this is closable as Not A Problem. If you disagree, please reopen?

> Key: COUCHDB-103
> URL: https://issues.apache.org/jira/browse/COUCHDB-103
> Project: CouchDB
> Issue Type: Bug
> Components: JavaScript View Server
> Affects Versions: 0.7.2, 0.8
> Environment: all
> Reporter: Damien Katz
> Assignee: Noah Slater
> Fix For: 1.2
>
>
> In the spidermonkey engine, we use a built-in function sealing for sealing
> documents so that map functions of arrays no longer works. Array sealing no
> longer works with javascript 1.8, meaning our document that contain arrays
> cannot be sealed. The sealing is meant to prevent map functions from
> modifying the same document that will be passed to other map functions.
> The (hopefully temporary) fix here is to simply remove the document sealing,
> and map function placed in the same design document will have to be
> trustworthy that they don't modify the document (the same document is passed
> to multiple map functions). Non-trustworthy map functions can be placed in
> their own design documents, they will be run in isolation.
