Issue with BrowserStack and OSX #221

Closed kitsonk closed 9 years ago

kitsonk commented 10 years ago

I am afraid I can't be more specific, because the issue seems to be non-specific to figure out what is going on. I am attempting to run the following environments on BrowserStack:

environments: [
    { browserName: 'internet explorer', version: '11.0', platform: 'win8' },
    { browserName: 'internet explorer', version: '10.0', platform: 'win8' },
    { browserName: 'internet explorer', version: '9.0', platform: 'windows' },
    { browserName: 'firefox', version: '29.0', platform: 'windows' },
    { browserName: 'chrome', version: '35.0', platform: 'win8' },
    { browserName: 'safari', version: '6.1', platform: 'mac' },
    { browserName: 'safari', version: '7.0', platform: 'mac' }
]

And every time, when we seem to hit the Safari/Mac environments, it craps out with an issue trying to read one of the files. My Node version is 0.10.28 and my Intern is 2.0.1. Out of an abundance of caution, I abundance of caution, I raised both my kernel.maxfiles and kernel.maxfilesperproc to see if it was just an issue with file handles not being released, but that didn't affect anything.

Here are a few examples:

Initialised safari 6.1 on MAC
Error: EMFILE, open '/Users/kitsonk/github/core/node_modules/intern/node_modules/dojo/errors/RequestTimeoutError.js'
No stack or location
Initialised safari 6.1 on MAC

Thanks for the report. This is https://github.com/joyent/node/issues/6041. We can work around it by destroying the read stream manually, in lib/createProxy.

I looked into this tonight and actually I can’t see any file handles being retained when I look using lsof. Once the file has finished being transmitted, it’s no longer held open by Node.js. So, I’ll need more information from you in order to reproduce the issue. To start with, right before the test runner crashes, could you please run lsof |grep node? If file handles are being retained you should see a big long list there.

(For reference, I tested on both Mac OS 10.9.4 and Linux using Node.js 0.10.29.)

kitsonk commented 10 years ago

It broke at a different point, so I didn't actually get the dump at the moment.

Initialised safari 7.0 on MAC
Error: EMFILE, open '/Users/kitsonk/github/core/node_modules/intern/lib/Suite.js'
No stack or location

I am on OSX 10.9.3. I will try NodeJS 0.10.29 and the OSX upgrade tomorrow.

Here it is (a big long list):

Upgraded to OSX 10.9.4 and NodeJS 0.10.29, same results. I also did an rm -rf ~/.npm, npm clear cache, rm -rf node_modules and then npm install.

csnover commented 10 years ago

And this is only when using the BrowserStack tunnel, not a plain Selenium server, and only when interacting with Safari?

kitsonk commented 10 years ago

I don't have just a plain Selenium server. I re-ordered my environments like this:

environments: [
    { browserName: 'safari', version: '6.1', platform: 'mac' },
    { browserName: 'safari', version: '7.0', platform: 'mac' },
    { browserName: 'internet explorer', version: '11.0', platform: 'win8' },
    { browserName: 'internet explorer', version: '10.0', platform: 'win8' },
    { browserName: 'internet explorer', version: '9.0', platform: 'windows' },
    { browserName: 'firefox', version: '29.0', platform: 'windows' },
    { browserName: 'chrome', version: '35.0', platform: 'win8' }
]

I get this as output:

Listening on 0.0.0.0:9000
Starting tunnel...
BrowserStackLocal v2.2
Ready
Initialised safari 7.0 on MAC
Initialised safari 6.1 on MAC

And it just "hangs" and I get Session timed out because the browser was idle for 90 seconds for each test in BrowserStack. I can see the full suite executes fine in the session, and just sits there trying to "post" back the results. I run the same tests locally in Safari 7.0.5 and it completes just fine.

If I switch to SauceLabs and adjust to:

environments: [
    { browserName: 'safari', version: '6', platform: 'OS X 10.8' },
    { browserName: 'safari', version: '7', platform: 'OS X 10.9' },
    { browserName: 'internet explorer', version: '11', platform: 'Windows 8.1' },
    { browserName: 'internet explorer', version: '10', platform: 'Windows 8' },
    { browserName: 'internet explorer', version: '9', platform: 'Windows 7' },
    { browserName: 'firefox', version: '29.0', platform: 'Windows 7' },
    { browserName: 'chrome', version: '35.0', platform: 'Windows 7' }
]

And I can't seem to get consistent test runs... some sessions just seem to hang and maybe I get a "clean" run 1 out of 10 times (which is why I was trying BrowserStack), but they do eventually run.

The only thing that might be odd, is my whole test suite at the moment takes about 6 seconds to execute.

csnover commented 10 years ago

Sorry, nobody has been able to reproduce this issue so far. I know that @jason0x43 has been running tests against BrowserStack without a problem, after they recently fixed some issues. Could you please try again and re-report whether the problem still exists?

jfridye commented 10 years ago

@csnover We have what appears to be a similar issue whilst running our unit tests on BrowserStack. Intermittently we get a timeout in BrowserStack for Firefox 31.0 on OS X and every time in Windows 7 environments, even though tests ran successfully. BrowserStack attempts to post back, but there is no resolve in our test runner, and the process hangs indefinitely until manually terminated.

We are on Intern 2.0.1 and Node v0.10.29.

csnover commented 10 years ago

@jfridye That doesn’t sound related, except that it’s a problem with BrowserStack, unless you also get an EMFILE error. Do you?

jason0x43 commented 10 years ago

What's timing out and what's hanging (between Intern and BrowserStack)? Like, is the Intern runner hanging forever and BrowserStack is timing out?

jfridye commented 10 years ago

We are not getting the EMFILE error.

The BrowserStack session terminates with a status of Session timed out because the browser was idle for 90 seconds. However, the Intern runner hangs forever with a last output of Initialised firefox 31.0 on XP until manually terminated. We are seeing this whether the test runner is executed from our dev machines or CI environment (Jenkins), and for every session in a Windows 7 environment on BrowserStack.

Could this be a problem with the configured value of proxyUrl being the default of http://localhost:9000?

Here is a sample of the last few lines of raw logs taken from a session on BS: https://gist.github.com/jfridye/2de70b4792128f78249e. Hope this helps, and thank you!

csnover commented 9 years ago

@jfridye Could you open a new issue? I don’t want to confuse two unrelated things. Thanks!

@kitsonk I’m going to close this for now since I haven’t heard anything since July, if you have time to loop back please let me know. Nobody at SitePen has been able to reproduce the EMFILE problem.

jfridye commented 9 years ago

To follow up on my comment above, we are no longer seeing the issue on BrowserStack, but are not sure what the root cause of the issue was. It is likely the case there was an issue in one of our unit tests that was causing the problem. If the problem comes up again and we are unable to troubleshoot, I will open a new issue against it. Thanks!
