0.11.14 on Windows ... "child_process: customFds option is deprecated" error

[stevenvachon]

I'm not using customFds anywhere in my code:

// util.js
function shell(shellfile, args, callback) {
    args = ["./"+shellfile].concat(args);
    child_process.execFile("node", args, {cwd:__dirname}, callback);
}

// cli.js
util.shell("meta/app", ["--input","folder/file.ext", "--output","folder/file.ext"], function(error, stdout, stderr) {
    // mocha+chai stuff
});

yet, I get this error when running Node v0.11.14:

npm : child_process: customFds option is deprecated, use stdio instead.
At line:1 char:1
 npm test # PowerShell

npm test is in my package.json

• This did not occur on Windows with v0.11.13
• This did not occur on Linux with v0.11.13 nor v0.11.14 (log)
• This only occurs on Windows with v0.11.14 (log)
• This kills my mocha test

This is only a deprecation message. The feature was deprecated in this commit. Even though your code isn't using it, it appears to be used in npm and mocha.

[stevenvachon]

But if it's just a warning, why does it make my mocha tests fail?

[chrisdickinson]

The deprecation notice is merely advisory output, and does not otherwise affect the flow of your program.

It might be a red herring -- there may be another issue that's causing the tests to fail. Alternatively, if your mocha tests are testing output (somehow) they might be getting the deprecation notice unexpectedly and failing.

As npm has dropped compatibility with Node 0.6, I'll be going through its code base and cleaning up its usage of customFds; it's worth pointing out that node-gyp also uses it, (as does CoffeeScript and promzard and probably many other things). Is the schedule to remove it by 1.0? Or (assuming there is one) 0.14?

I don't know who uses customFds but I am really not happy
