fs,net: emitting ready event for fs streams and network sockets in addition… by sameer-coder · Pull Request #19408 · nodejs/node · GitHub

… to the event names they currently use.

Currently, various internal streams have different events that indicate that the
underlying resource has successfully been established.

fs streams use the open event once the file descriptor is available
net.Sockets use the connect event once the socket has been established
Http2Streams use the ready event once the underlying http/2 session is established

This commit adds ready event for fs and net sockets to standardize on emitting ready for all of these streams.

Fixes: #19304

Thank you for picking this up!

I would omit fd here, the other streams don’t have this on the event (and it doesn’t make sense to have it for Http2Stream)

I have removed thefd for the ready event.

I guess a lot of these blocks are taken from another test? It might be good to reduce the file so that only the one with the ready event remains

I have removed all the extra blocks and made it a minimal testcase to only check for ready event.

Thanks @addaleax I have been a bit busy so couldn't update yet. I will make the changes as per your feedback today and commit again.

Thanks a lot @addaleax for your guidance ;)

Should we add documentation for these new events?
