Error: EAGAIN during readSync

[noahseger]

Similar to #7, we've seen stdin fail as the number of protobufs we're processing has increased:

buf generate
node:fs:738
  handleErrorFromBinding(ctx);
  ^

Error: EAGAIN: resource temporarily unavailable, read

Running under Node 16 in GitHub Actions:

        with:
          node-version: 16

All I've found so far is https://stackoverflow.com/questions/40362369/stdin-read-fails-on-some-input, and I don't know if you have the flexibility to read synchronously from /dev/stdin for portability.

Hey @noahseger, thanks for reporting. What version of twirpscript are you running?

[tatethurston]

I think I may have found a lead here: nodejs/help#2663. I'll put out a release switching to process.stdin usage. Once I release that, if you could let me know if the issue stops or if you continue to see it, I'd really appreciate it.

Hi @tatethurston , thanks for checking it out! We're running 0.0.61, and can definitely let you know whether or not it stops after that lands. This framework is the best 🤘

[tatethurston]

Awesome thanks Noah, I’ll let you know when I publish

[tatethurston]

This is fixed in 0.0.66. LMK if you run into any issues!

[noahseger]

Thanks @tatethurston! This passed our CI so we'll land it and watch for the error over the next week 🎉

[tatethurston]

Thanks @noahseger!

@noahseger how has the incidence of this error looked after 0.0.66?

[noahseger]

Hey Tate, seems super solid since we upgraded. Thanks again 🙌
