Requests after long delays halt on tls.js:182

(Not sure if the express part matters, but takes 30+ minutes to do a test to see if it fails as expected so this the least I got it cut down to to confirm the bug)

Just run this, and after about 30-60 minutes you should get

TypeError: Cannot read property 'CN' of undefined
    at Object.checkServerIdentity (tls.js:182:37)
    at TLSSocket.<anonymous> (_tls_wrap.js:1016:29)
    at emitNone (events.js:67:13)
    at TLSSocket.emit (events.js:166:7)
    at TLSSocket._finishInit (_tls_wrap.js:566:8)

Very interesting... I think I figured it out, will let you know once I'll test the change :)

Not sure if I will be able to provide a proper test case, though.

[sadtaco]

If you can figure out some sort of workaround without having to wait for an iojs update, that'd be really amazing too. I need this working fairly badly.

Maybe like a try { request } catch { //new-session-thing }? Dunno really.

[indutny]

The only workaround that I could think of at the moment is following:

var https = require('https');

var agent = new https.Agent();

agent._getSession = function nop() {};

var request = require('request').defaults({ agent: agent });

This is the only way to disable session cache atm.

[sadtaco]

I just tried that, at least I believe I set it up right.

var request = require('request').defaults({jar: true, agent: agent})

to be exact. But I still got the same error.

Here is some debugging data, just for reference:

[indutny]

@sadtaco let me test it locally, perhaps I did a mistake there...

[indutny]

@sadtaco appears to be fixing problem for me. Are you sure that you are reusing the request.defaults({ ... }) output everywhere?

[sadtaco]

I don't get what you mean. Are you asking if I'm resetting the request variable to something else elsewhere?
Nope, I'm not. It's just the one "request = require('request').defaults({jar: true, agent: agent})"

[indutny]

@sadtaco I wasn't sure if you was doing requests from a single js file, or not.

It is very odd that the problem is still happening for you, as it does not seem to be reproducible on my machine with these changes (and it is without them). I'm going to work on the test case, and will submit a PR as soon as I'll be able to reproduce it reliably.

[sadtaco]

Yeah, in a single file. Not really different from the test case I posted. Only difference is that it's triggered by an app.get('/...') instead of the setInterval.
Ah well, it's fine.

[indutny]

Argh, I think I know why it wasn't working for you. May I ask you to give a try to:

var https = require('https');
var util = require('util');

function Agent() {
  https.Agent.apply(this, arguments);
}
util.inherits(Agent, https.Agent);

Agent.prototype._getSession = function nop() {};

var request = require('request').defaults({ agentClass: Agent });

[indutny]

Ok, I know how to reproduce it ;) Hehe, will post a PR soon!
