Subject [jira] Commented: (COUCHDB-925) altering 'doc' variable in map function affects other map functions
Date Mon, 22 Nov 2010 15:47:13 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934490#action_12934490

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.

>             Project: CouchDB
>          Issue Type: Bug
>    Affects Versions: 1.0.1
>         Environment: Erlang R13B03, Spidermonkey 1.7, Ubuntu 10.04
>            Reporter: afters

> 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.
