Node 0.12 and io.js support

[TheFifthFreedom]

First of all, I'm glad to see someone finally open-sourcing a serious and well-maintained re-implementeation of the Selenium Grid using NodeJS: thanks @arikon ! Now since it seems that selenodium-grid is not in the npm registry as of yet, instead of running npm -g install selenodium-grid, I tried to install it manually. However when running npm install (with an updated npm otherwise the ˆ signs in package.son will not be interpreted properly) I encountered an error when trying to rebuild node-gyp:

> gaze@0.6.4 install /Users/lmazou/Downloads/selenodium-grid-dev/node_modules/luster-guard/node_modules/gaze
> node-gyp rebuild

child_process: customFds option is deprecated, use stdio instead.

After a bit of digging around, I correlated this issue with this one: https://github.com/TooTallNate/node-gyp/issues/489. This seems to happen on OS X with NodeJS versions beyond 0.10 (I'm running Yosemite 10.10.2 with NodeJS 0.12.0). Just like the issue suggests, downgrading to NodeJS 0.10.X does the trick. So not something you can do much about @arikon, but I thought I'd let you know!

@TheFifthFreedom Thanks for the report!

Yes, the problem is with gaze and node-gyp. I've also hit it.

First of all, I'm glad to see someone finally open-sourcing a serious and well-maintained re-implementation of the Selenium Grid using NodeJS

It is still a work in progress. I will be glad if someone could join the forces to make it a really good reimplementation.

For now I'm in a stage of reimplementing registry and store so it:

• run more than 1 test on a single node
• respect nodes timeout options
• store node descriptors and sessions not just in the memory of the single process, but somewhere outside (etcd, consul) to get it run as a multiple process and on many machines

[TheFifthFreedom]

Well I'd be glad to help in any way I can - it will just take me a bit of time to get acclimated with your implementation first. One other thing I've noticed is that once I've installed the necessary dependencies via npm install after downgrading NodeJS version, I run ./bin/selenodium-grid as you described in your readme, but as soon as I try to attach a node using the Selenium Standalone Server using java -jar selenium-server-standalone-2.45.0.jar -role node -hub http://127.0.0.1:4444/grid/register, the node can't connect to the hub somehow:

Would you happen to know what's going on? (I'm running the dev branch code)

[TheFifthFreedom]

It looks like the issue happens when the Selenium node is sending a POST request which is routed to /grid/register - as per register.js:

module.exports = function(req, res) {
    if (!req.data) {
        return q.reject(apps.content('Invalid parameters', 'text/plain', 400));
    }

    return q.invoke(registry, 'addNode', req.data)
        .catch(function() {
            return q.reject(apps.content('Invalid parameters', 'text/plain', 400));
        })
        .then(function(success) {
            if (success) {
                log.info('Register new node: %s', JSON.stringify(req.data));
                return apps.content('ok');
            }
            return q.reject(apps.content('Invalid parameters', 'text/plain', 400));
        });
};

the code is trying to access req.data which doesn't exist. I did try to print the JSON request the server receives from the Selenium node:

and there's indeed no data to be found, which explains the node rejection. What I believe the server is expecting is something along those lines:

{"class":"org.openqa.grid.common.RegistrationRequest","configuration":{"register":true,"port":5555,"host":"10.211.100.178","proxy":"org.openqa.grid.selenium.proxy.DefaultRemoteProxy","maxSession":5,"role":"node","hubHost":"localhost","registerCycle":5000,"hub":"http://localhost:4444/grid/register","hubPort":4444,"url":"http://10.211.100.178:5555","remoteHost":"http://10.211.100.178:5555"},"capabilities":[{"platform":"MAC","seleniumProtocol":"Selenium","browserName":"*firefox","maxInstances":5},{"platform":"MAC","seleniumProtocol":"Selenium","browserName":"*googlechrome","maxInstances":5},{"platform":"MAC","seleniumProtocol":"Selenium","browserName":"*iexplore","maxInstances":1},{"platform":"MAC","seleniumProtocol":"WebDriver","browserName":"firefox","maxInstances":5},{"platform":"MAC","seleniumProtocol":"WebDriver","browserName":"chrome","maxInstances":5},{"platform":"MAC","seleniumProtocol":"WebDriver","browserName":"internet explorer","maxInstances":1}]}

which is standard Selenium Grid request format. I haven't figured out yet why that happens - could it have something to do with the http server implementation that is used here, which comes from q-io?

[arikon]

@TheFifthFreedom It was fixed here https://github.com/selenodium/selenodium-grid/pull/14.

Try the latest commit from dev.

[arikon]

Reopening for the gyp-rebuild

[arikon]

@TheFifthFreedom Please open separate issue the next time, to not mix things up ;)

[TheFifthFreedom]

You're right - my mistake, sorry about that!

[arikon]

@TheFifthFreedom Have you figured out how to launch selenodium-grid?

[arikon]

@TheFifthFreedom I've created a bunch of issues if you want to help. For now all the modifications should be made to the feature/new-registry branch.

[eranimo]

Any update on this? I still have problems on latest version of node

[arikon]

@eranimo No updates for now.

The problem is in the luster-guard https://github.com/nodules/luster-guard dependency gaze https://github.com/shama/gaze

Any help is welcomed.
