Description of change

This fixes an issue reported in #5684 about module in node_modules being preferred over a local file with the same name, when resolved in repl (or --eval mode). The bug originates from the fact that Module._resolveLookupPaths() puts node_modules before the current directory when run from repl or --eval.

Previous results from Module._resolveLookupPaths('./lodash'):

[ './lodash',
  [ '/Users/phillipj/Dev/repl-lookup-test/node_modules',
    '/Users/phillipj/Dev/node_modules',
    '/Users/phillipj/node_modules',
    '/Users/node_modules',
    '/node_modules',
    '.',
    '/Users/phillipj/.node_modules',
    '/Users/phillipj/.node_libraries',
    '/Users/phillipj/Dev/node/out/lib/node' ] ]

Fixed results from Module._resolveLookupPaths('./lodash'):

[ './lodash',
  [ '.',
    '/Users/phillipj/Dev/repl-lookup-test/node_modules',
    '/Users/phillipj/Dev/node_modules',
    '/Users/phillipj/node_modules',
    '/Users/node_modules',
    '/node_modules',
    '/Users/phillipj/.node_modules',
    '/Users/phillipj/.node_libraries',
    '/Users/phillipj/Dev/node/out/lib/node' ] ]

@phillipj thanks for getting this in! I think it might make sense for you to include an extra test that I have written that can be found in MylesBorins@7f2f0cb

To quickly add that commit to your branch you can run the command

$ curl https://github.com/TheAlphaNerd/node/commit/7f2f0cb946d7889fcdef7aff9d895574da9c14b3.patch | git am --whitespace=fix

MylesBorins · 2016-03-13T21:12:09Z

@phillipj it looks like your test is failing the linter

/Users/thealphanerd/code/node/test/parallel/test-module-relative-lookup.js
   3:5  error  'common' is defined but never used             no-unused-vars
  11:1  error  Line 11 exceeds the maximum line length of 80  max-len

phillipj · 2016-03-13T21:13:08Z

Thanks for the protip cherry-picking that with ease @thealphanerd! Would you prefer two commits or should I squash your test into my initial commit?

phillipj · 2016-03-13T21:14:04Z

it looks like your test is failing the linter

Yupp, sorry about that. Just pushed an updated.

MylesBorins · 2016-03-13T21:15:43Z

@phillipj I would keep them separate as you didn't write the code. Better to keep the blames on who wrote it 😄

phillipj · 2016-03-13T21:18:28Z

@thealphanerd haha good point :)

MylesBorins · 2016-03-13T21:19:27Z

once you push the update I'll run CI + citgm... this is one of those fixes that could be argued to be either patch / major... let's see what we break 😄

phillipj · 2016-03-13T21:19:30Z

CI: https://ci.nodejs.org/job/node-test-pull-request/1914/

citgm: https://ci.nodejs.org/job/thealphanerd-smoker/112/

It looks like things in smoker land might be weird... the results might not be useful until I have more time to dig into infra problems tomorrow

phillipj · 2016-03-13T21:28:03Z

Alright, fingers crossed CI will pass at least.

MylesBorins · 2016-03-13T21:53:15Z

CI looks good... only failure was infra related

benjamingr · 2016-03-13T23:32:38Z

LGTM. Thanks for the quick fix.

MylesBorins · 2016-03-13T23:40:10Z

citgm has some failures, but they all seems to be unrelated. I would like to try and get another run going tomorrow though to confirm

evanlucas · 2016-03-14T03:36:45Z

Was this a regression or has this always been the behavior?

mscdex · 2016-03-14T07:19:29Z

@evanlucas The behavior before this PR has existed at least since v0.10.

/cc @nodejs/ctc

phillipj · 2016-03-18T14:23:18Z

I'm assuming @nodejs/ctc got pinged for a patch/major decision.

Although I fully acknowledge the fact we have to be a little too careful at times about what's decided to be a breaking change, I see this as a bug and therefore a patch.

FWIW I can't imagine someone out there relying on not being able to require their own local .js-file because it's over shadowed by a 3rd party module. That's very confusing at best and could potentially be a debugging nightmare.

Some comments, but LGTM pending CI.

@Fishrock123 that stylus bug is unrelated

phillipj · 2016-03-29T18:48:11Z

@thealphanerd which means this is ready to land as is, right?

MylesBorins · 2016-03-29T18:49:31Z

none of the citgm results are a problem.

Fishrock123 · 2016-03-29T19:13:14Z

@phillipj I believe so. LGTM 🚢
