test/parallel/test-process-execpath.js

+assert.strictEqual(process.execPath, fs.realpathSync(process.execPath));
+
+if (process.argv[2] === 'child') {
+  console.log(process.execPath);


can you please add a comment mentioning at the the console.log() output here is part of the test

@jasnell done!

…test here.”

I’ve set the test to skip on Windows since I don’t know if it even makes sense there… if somebody in @nodejs/platform-windows has an opinion, feel free to voice that :)

test/parallel/test-child-process-exec-error.js

+if (common.isWindows) {
+  common.skip('symlinks are weird on windows');
+  return;
+}


Why is the above check done? The test does not use symlinks. (If there is a good reason to skip the test, then the check for common.isWindows below can be removed.)

(Looks like this was meant for test-process-execpath.js and not test-child-process-exec-error.js?)

Is it possible you accidentally added the skip to the wrong file? Looks that way to me...

That is totally possible. Updated! 😄

This works on Windows if you use 'symlinked-node.exe'. But the test fails and confirms that execPath is not a realpath.

… silly me. Thanks for pointing that out!

But the test fails and confirms that execPath is not a realpath.

Sounds to me like that should be considered a bug, or at least an OS-specific difference that should be documented?

joaocgreis · 2016-10-26T12:12:30Z

Looks like a bug to me, I'll take a look.

@addaleax If you want to land, include the Windows skip and I'll remove it with the fix.

Reviewing, the code looks good, but what's the motivation for this? Consistency sounds good, do we imply this somewhere in the docs or would it be just a nice to have?

It came from discussion around an npm change of mine, npm/npm#14374. We weren’t quite sure whether applying fs.realpathSync to process.execPath makes sense or not, so I got curious and wanted to see whether the behaviour is consistent (and if it is, try to get a test for that in here).

So, yes, it’s just nice to have, not something we guarantee in our docs right now.

addaleax · 2016-11-13T21:52:06Z

Would anybody mind giving this a look? (@joaocgreis … was that an affirmative review?)

(@addaleax I missed that last mention, sorry 😔)

Found this libuv PR: libuv/libuv#293 . Doesn't look like we have reasons here to push it farther than it went, so no real execPath on Windows for now.

addaleax · 2016-12-06T17:42:59Z

@joaocgreis Thanks for followingup! I kind of wonder if we should just apply Node’s fs.realpath here… but then again maybe it’s best to just leave this alone. ;)
