relay-compiler --watchman false option fails with FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal. when --src is current directory

[stevehollaar]

Using version 1.2.0

This seems to only happen when src is the current directory: .

./node_modules/.bin/relay-compiler --src . --schema ./schema.json --watchman false                                                         Thu 17 Aug 11:11:25 2017

Setting src to a subdirectory works as expected:

node_modules/.bin/relay-compiler --src app --schema ./schema.json --watchman false                                                1538ms  Thu 17 Aug 11:14:01 2017

I can confirm this on v1.4.1

@stevehollaar did you find a workaround for this?

[simenbrekken]

I started digging a bit into this and found that readdir-enhanced which fast-glob utilizes recurses into every directory starting from src including node_modules.

The filtering as specified by exclude seems to be performed after reading everything. I suspect symlinks inside of node_modules could be the culprit but I wasn't able to pinpoint the root cause.

My current workaround for a next.js project is explicitly specifying source directories relative to src: relay-compiler --src . --include components/** --include pages/**

I can't think of a smart way to fix this based on @simenbrekken's observations. Any thoughts on this?

If nothing else, I think specifically showing a descriptive error message when --src === "." and the "--exclude" option is used like this could be useful (as a last resort):

You cannot use "--src ." in conjunction with the "--exclude" flag, please use "--include" instead or move your source files into a dedicated source directory"

I think this was working with node 6, but is broken now with node 8. I opened an issue in the fast-glob repo: https://github.com/mrmlnc/fast-glob/issues/23

[steida]

watchman option still does not work.

[jstejada]

@steida, what do you mean that it still doesn't work? Which version of node are you running? Did you try @simenbrekken's workaround?

[steida]

Yes, I tried. Node 8.9.4. With --watchman false I get: (both locally and in circle ci)

[steida]

Why is watchman needed without watching anyway? Does anybody know how to install it on circle-ci 2? Thank you.

Hello, @steida,

Unfortunately, this does not looks like a bug inside my package (fast-glob).

I see that you trying to pass the following set of patterns to the fast-glob package:

[ 'components/A.js/*.+(js)',
  'components/AreYouSureConfirm.js/*.+(js)',
  // …
  'components/editor/*.+(js)',
  'mutations/CreateWebMutation.js/*.+(js)',
  // …
  'mutations/utils/*.+(js)',
  'pages/__generated__/*.+(js)',
  // …
  'pages/sign-in.js/*.+(js)' ]

But I see that you have the following tree on the file system:

./components/
├── A.js
├── AreYouSureConfirm.js
├── …
├── WebsItem.js
├── __generated__
│   ├── …
│   └── WebsItem.graphql.js
├── app
│   ├── …
│   └── index.js
├── buttons.js
└── editor
    ├── …
    └── logReducer.js

When you pass a pattern like components/A.js/*.+(js), then you say that you want to find all files with .js extension inside the components/A.js directory.

JFYI: This is the Task that was created for your pattern:

{
  base: 'components/A.js', // The parent directory 
  dynamic: true,
  patterns: [
    'components/A.js/*.+(js)',
    '!**/node_modules',
    '!**/__mocks__',
    '!**/__tests__',
    '!**/__generated__'
  ],
  positive: [
    'components/A.js/*.+(js)'
  ],
  negative: [
    '**/node_modules',
    '**/__mocks__',
    '**/__tests__',
    '**/__generated__'
  ]
}

This issue related to wildcards inside npm scripts. Before sending the patterns to the script, they are expanded by shell. You should wrap the patterns in quotation marks:

relay-compiler --src . --include 'components/**' 'mutations/**' 'pages/**' --schema server/schema.graphql,

Or "" if you use Windows also.

After it all works fine:

[ 'components/**/*.+(js)',
  'mutations/**/*.+(js)',
  'pages/**/*.+(js)' ]

@mrmlnc Wow, it works. Finally, :-) Thank you ❤️
