Bug since v2.0.0 — RangeError: Maximum call stack size exceeded

[maxmilton]

Environment

• OS Version: Fedora Linux 4.14.14-300.fc27.x86_64
• Node.js Version: v9.4.0

Actual behavior

Since v2.0.0 an error is thrown when run on a filesystem. Number of files/dirs is 54/18 in my case.

Call stack:

yarn run v1.3.2
$ OVERRIDE_ENV=development npm run build

> [email protected] build /home/max/Development/example/packages/app
> APP_RELEASE=$(git describe --always) NODE_ENV=production node build/build.js

/home/max/Development/example/node_modules/fast-glob/out/providers/reader-sync.js:40
            throw err;
            ^

Looks to be related to readdir-enhanced.

Expected behavior

fast-glob runs without any error thrown.

Steps to reproduce

1. Nothing specific, just run fast-glob.

Code sample

const fastGlob = require('fast-glob');

const paths = fastGlob.sync([
  path.join(__dirname, './**/*.html'),
  path.join(__dirname, './**/*.js'),
]);

NOTE

Since v2.0.0 has removed bashNative mode, I'm actually going to pin my fast-glob version to 1.0.1 anyway since I want that native level of performance. That was actually the reason why I started using fast-glob in the first place!

Hello, @maxmilton,

You can provide find . | wc -l and tree -L 1 output for your __dirname directory? I think you have a very large project directory. Also fast-glob@2now faster then bash-glob (it is possible that not in all cases).

[maxmilton]

The number of files in my project root is large, total dirs+files = 27405. Also the tree:

.
├── build
├── config
├── dist
├── index.html
├── jsconfig.json
├── node_modules
├── package.json
├── src
├── static
├── test
└── yarn.lock

7 directories, 4 files

Does fast-glob search the entire project from the __dirname? My specific use case is similar to this:

build/conf.js:

fastGlob.sync([
  path.join(__dirname, '../index.html'),
  path.join(__dirname, '../src/**/*.vue'),
  path.join(__dirname, '../src/**/*.js'),
]),

That's good to hear v2 is faster, obviously I haven't been able to test.

[mrmlnc]

Thanks for provided details.

I'll work on your problem tonight. Now you can exclude node_modules directory from reading by !**/node_modules pattern. Also you can exclude dest and other not needed directories.

Sorry for this situation.

[maxmilton]

Using your recommended excludes I'm able to run without any errors. For anyone else's reference, my updated and working code is:

fastGlob.sync([
  '!**/node_modules',
  '!**/dist',
  path.join(__dirname, '../index.html'),
  path.join(__dirname, '../src/**/*.vue'),
  path.join(__dirname, '../src/**/*.js'),
]),

This is fine for me so feel free to close this issue.

[maxmilton]

After reading the documentation more closely I realised fast-glob starts the search from process.cwd() so I was able to simplify things:

fastGlob.sync([
  '!node_modules',
  '!dist',
  'index.html',
  'src/**/*.vue',
  'src/**/*.js',
]),

Thank you for your hard work on this project 🥇

[mrmlnc]

Well, I need to understand what's going on.

If you have free time, then tell me how much free memory you have on the server?

I checked work of this the package on directories with more than 500 000 files and it just works. But I have 16GB RAM and a heap of V8 has a size of 1.4 GB.

Maybe I can use a more intelligent index for occurrences or try to exclude the directories like .git, node_modules by default. So...

So, it's just a working theory. Maybe i'm wrong.

[mrmlnc]

So, we well work on the solution here:

• Maximum call stack size exceeded with filters JS-DevTools/readdir-enhanced#11

[mrmlnc]

@maxmilton,

Please, try to use npm i fast-glob@next --force for your broken cases. I tried to fix the problem with large directories, temporarily switching to the readdir-enhanced fork.

[maxmilton]

Sorry I hadn't gotten back to this thread sooner. I can confirm on the current v2.0.4 the issue I originally raised is no long reproducible.

Thank you for your hard work on this project! 🌟
