Spidermonkey's sandboxing capabilities vary release to release. As I recall, we had full sandboxing working with earlier releases, but something changed in 1.7 and we took it out.

Grasping the concepts involved in map/reduce might end up being a significant hurdle to CouchDB adoption so I would encourage features that assist in that regard. Sandboxing might also be necessary to enforce whatever is ultimately CouchDB's security model.

Spidermonkey must have sandboxing capabilities if it runs the javascript for both the Firefox browser and the web pages it loads.

Paul's case of caching large objects is something to consider (and a reason my previous email was not strictly correct) but could perhaps be handled more formally or left to custom view servers.

Should CouchDB not restrict defining state outside the map function?
I.e. you should not be able to declare a counter outside the function?

You can't maintain a state across calls to map functions in this way. Map functions can be called in any order or in parallel, any number of times on a particular document and in completely separate environments. They should
not have any side effects or depend on any outside state.

You should read up on Google's MapReduce and maybe functional programming in
general in order to understand how CouchDB works.

If you just want to number the results of your view, that can be easily done
by the calling code.

Hi,

I've got the following view:

count = 0;
function(doc) {
if(doc.type == "document") {
  count = count + 1
  emit(doc._id, count);
}
}

The idea is that I get a list of documents, each having a counter
value which is incremental. I expected the count values to come out in order, but that isn't the case: my first few documents have values of
62, 61, 22, 19. I'm not quite sure what's going on here - any ideas
how the order is being set here?
