Jason Smith commented on COUCHDB-1894:
--------------------------------------

A note on terminology (at least to my understanding).

My work is not a "query server" but rather (I guess) a "JavaScript 
environment". All it does is run some JavaScript code and provide a few globals 
like readline(), print(), and a few others.

The "query server" is the stuff in share/server/*.js, which is compiled into 
one big main.js during building. My project runs the query server verbatim, and 
so it is a drop-in replacement for couchjs except using v8 instead of 
SpiderMonkey. (That is not very interesting for users, it feels 100% the same. 
What is interesting is that it is easier to install.)

> 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
