Benoit Chesneau commented on COUCHDB-1894:
------------------------------------------
releasing new features is fine. But I would be really cautious on that one, the
last thing we want is to break a machine because we used too much ram, cpu or
whatever. Which can happen very rapidly on a loaded machine with a lot of view
indexations or filtered replications.
In this case I don't think it's really difficult to go for the model I describe
from the current patch anyway this is "just" a matter of having the dispatching
done at another level. All what I say is that it may worth to take the time to
see if this patch could be improved that way.
We can iterate in different branches or not. Like I see it there could be 2
works done simultaneously on that patch:
- check/improve the sandboxing
- try to improve the multiprocessing model
At some point we can just decide to ship the current version ("current" as the
working version at the time we are looking at it) and continue to iterate on
top of it. But I don't see the point of having 2 tickets for the same feature.
nothing stop us to keep open a ticket across release until we know the state in
the shipped release.
> Add experimental NodeJS query server
> ------------------------------------
>
> Key: COUCHDB-1894
> URL: https://issues.apache.org/jira/browse/COUCHDB-1894
> Project: CouchDB
> Issue Type: New Feature
> Components: JavaScript View Server
> Reporter: Jan Lehnardt
>
> Let’s clean up and merge Jason Smith’s Node.js query server into ASF land and
> ship it as opt-in and experimental.
> I’ve prepared a branch that does the following:
> - remove fancy extra features like app server handlers and the visual
> debugger support for now
> - make it a drop-in replacement for couchjs
> - bundle the code in src/couchjs-node
> - add a new query server language “nodejs” that people can use
> - include sandbox.js from https://github.com/KlausTrainer/sandbox.js (not
> hooked up yet)
> The query server is not installed by default and users can install them in
> two ways:
> 1. from source:
> $ cd src/couchjs-node
> $ npm link
> 2. from NPM:
> $ npm install couchjs # add @1.x.x for once the module mirrors CouchDB
> version numbers for forward compat)
> And then they can uncomment and update the [query_server] line in local.ini.
> * * *
> Open work items on the view server:
> - make it work with CLI tests
> - fix remaining test cases in web test runner
> - hook up sandbox.js from https://github.com/KlausTrainer/sandbox.js
