Can you also do this for TLS, so that #34958 is fully covered? :)

Not very sure I understand, in fact I shamelessly copied that from the TLS code?
#34958 seems to be an alternative implementation of the same problem?

Ah, right :) Cool. I’ll close my PR. :)

mmomtchev · 2020-10-16T12:12:22Z

That PR has one drawback: it doesn't allow for the user code to listen for remote_settings - when the data is already waiting in the socket, remote_settings will be sent before the user callback has been installed

Thanks for the patch :)

mildsunrise · 2020-10-18T11:55:37Z

I still think I prefer @addaleax approach (using JSStreamSocket in these cases) because it's simple and doesn't require us to add 'inject' logic to every native handle, doesn't have the drawback mentioned here, and can be reverted easily once/if we fix this properly in StreamBase. But no big deal, let's fix this for now and we'll see :)

hmm, this landed as two separate commits instead of squashing them into one... what do we do in these cases?

mildsunrise · 2020-10-25T11:50:46Z

it's still (almost) at the tip of the branch, I volunteer to do a force push to undo and land properly if given permission... if it's too risky we can leave it like that
