Paul Joseph Davis commented on COUCHDB-925:
-------------------------------------------
Has this been tested with a spidermonkey that's actually broken? It looks fine
to me but it might be a good idea to try and find one of the old versions to
double check the behavior.
Regardless, I'm +1 on committing.
> altering 'doc' variable in map function affects other map functions

> Key: COUCHDB-925
> URL: https://issues.apache.org/jira/browse/COUCHDB-925
> Project: CouchDB
> Issue Type: Bug
> Affects Versions: 1.0.1
> Environment: Erlang R13B03, Spidermonkey 1.7, Ubuntu 10.04
> Reporter: afters
> Attachments: COUCHDB-925.patch
>
>
> I have the following two map functions (v1.0.1):
> function (doc) {
> emit(doc.path[0], null);
> }
> function (doc) {
> doc.path = [ 'an intruder from another view' ];
> }
> When the views are built, the first map function sees a 'doc' variable that
> was changed by the second map function, and thus emits the key 'an intruder
> from another view'.
> The real documents remain untouched.
