• [BUG] yarn workspaces foreach run prefix string will mess up console, when sudo. yarnpkg/berry#6667

• seems like nodejs console race condition bug when sudo nodejs/node#56837

summary

Until now, have not yet been confirmed as bug by nodejs and yarn.

Below is summary based on my current understanding of this problem.

I think

• This is a nodejs + deno race condition bug when sudo

• This may called yarn berry bug, depends on individual preference.

brief

https://github.com/loynoir/reproduce-yarn-berry-6667

  "scripts": {
    "reproduce": "yarn workspaces foreach --all --exclude . run reproduce",
    "workaround": "yarn workspaces foreach --all --exclude . run workaround",
    "simulate": "yarn workspaces foreach --all --exclude . run simulate"
  }

  "scripts": {
    "reproduce": "sudo node ./simulate.mjs",
    "workaround": "deno run -A ./workaround.ts",
    "simulate": "node ./simulate.mjs"
  }

script	console
yarn reproduce	mess up
yarn workaround	OK
yarn simulate	Ok
DISABLE_WORKAROUND=1 yarn workaround	mess up

node

Because

• yarn simulate console OK

Which means

• yarn berry logic is fine.

But

• yarn reproduce console mess up.

• yarn workaround console OK

Which means

• There is a way, I have not yet have time to extract logic out from yarn berry, leads to sudo XXX console is not isomprphic to XXX console.

• There is also a way, let sudo XXX console isomprphic to XXX console

• sudo XXX console is not always isomprphic to XXX console

I think

• This is a nodejs race condition bug when sudo.

yarn

Because

• yarn reproduce console mess up.

• yarn workaround console OK

• yarn simulate console OK

I think

• This may called yarn berry bug, depends on individual preference.

deno

Because

• yarn workaround console OK

• DISABLE_WORKAROUND=1 yarn workaround console mess up

I think

• This is a deno race condition bug when sudo without async iterator.
