process,tty: allow reading/writing from duplex sockets : backport to node-8

[shrikrishnaholla]

• Version: 8.14.1
• Platform: Linux
• Subsystem: process/tty

Based on @mcollina 's advice in #21654 (comment)

Incrementing libuv version (to 1.20.x+. Release note - 8.13.0) has caused a regression in 8.x that causes stdout, stderr to throw when you try to read from it.

Quoting @mcollina from the referenced PR

We should likely backport part of #23053 to Node 8.

Did we backport libuv updates without those fixes? 😕

We probably want these commits from v10.x:

• d7031df
• 5a30674
• cb68188
• 748d9d2
• Maybe more.

I’ll try to get to it when I can, but if somebody else has the time, please go for it…

[mcollina]

We didn't.

However:

process.stdout.on('data', function(data) {
  process._rawDebug(data.toString())
})

Works in 8.15.0.

@shrikrishnaholla can you please post a working repro for this?

[mcollina]

I did the backports in #25351.
