Document sealing no longer works with Mozilla spidermonkey 1.8
--------------------------------------------------------------
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: Damien Katz
Fix For: 0.8.1
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.
