EMFILE when using fse.readFile

[chscott]

• Operating System: Windows
• Node.js version: 12.8.1
• fs-extra version: 9.0.1

I'm seeing the following with this code snippet and a large number of files being read:

const contents = await FSE.readFile(path, {
        encoding: 'utf8',
        flag: 'r',
      })

2021-01-19 16:25:47:147 - error: [main] Error: EMFILE: too many open files, open 'C:\ProgramData\foo.dat'

The readme indicates fs-extra uses graceful-fs to prevent EMFILE errors, but I also see some issues where it was reported that fs-extra wasn't using EMFILE in all cases. For example, #275 and #103. Is this another case where fs-extra doesn't use graceful-fs?

Nope, graceful-fs is used everywhere; have you verified the full stack trace of your error to ensure it's coming from this fs-extra call?

Thanks for verifying. I suspect you are correct and that it's not coming from where I thought it was.
