Issue with JRuby/SSL #30

ioquatix · 2019-10-04T23:33:13Z

Sorry for the delay, I finally got back to digging into this. I'm not sure if this is jruby specific or if it is something else, but I get these errors when I try to use the cloudflare gem with a proxy:

It appears that it is making a connection to the proxy (from the squid access logs):

1570193980.519    305 127.0.0.1 TCP_TUNNEL/200 39 CONNECT api.cloudflare.com:443 - HIER_DIRECT/2606:4700::6810:1f5a -
1570193980.581     53 127.0.0.1 TCP_TUNNEL/200 39 CONNECT api.cloudflare.com:443 - HIER_DIRECT/2606:4700::6810:1f5a -
1570193980.657     68 127.0.0.1 TCP_TUNNEL/200 39 CONNECT api.cloudflare.com:443 - HIER_DIRECT/2606:4700::6810:1f5a -

This is how I am configuring the cloudflare connection (simplified version):

endpoint = Async::HTTP::Endpoint.new(URI::HTTP.build(Settings.http_proxy.to_h))
client = Async::HTTP::Client.new(endpoint).proxied_endpoint(::Cloudflare::DEFAULT_ENDPOINT)
Cloudflare.connect(endpoint, Settings.cloudflare.credentials, &block)

Any thoughts on things that could potentially be misconfigured?

What platform are you running on?

ioquatix · 2019-10-04T23:34:44Z

@headius are there any limitations using pipes on JRuby? i.e. can't select for readability on windows or some other weird shit?

ioquatix · 2019-10-04T23:35:56Z

@rdubya can you try using NIO4R_PURE=true environment before running your script/command and let me know if that changes anything.

headius · 2019-10-05T17:49:43Z

@ioquatix Nothing comes to mind, but Windows pipes are a little weird at times. If we can get a reproduction with -Xbacktrace.style=full passed to JRuby I can look into it (probably best as a JRuby issue).

rdubya · 2019-10-07T14:59:12Z

@ioquatix I am running on os x 10.14 with JRuby 9.2.8.0.
My java env is:

java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

I ran with the pure env variable and got this result:

One interesting difference to note is that with NIO4R_PURE=true I only get 1 error but with it off I see 3 errors.

Okay this is enough information for me to repro, I'll try to do it.

rdubya · 2019-10-17T12:10:19Z

@ioquatix Have you had a chance to take a look at this? Is there anything else you need from me?

ioquatix · 2019-10-17T19:03:52Z

@rdubya Sorry, will review this weekend.

ioquatix · 2019-10-25T05:05:54Z

@rdubya sorry for the delay in attending to this issue, I have been completely snowed under with work and an upcoming presentation about async. I am working on this now.

ioquatix · 2019-10-25T08:11:44Z

@rdubya have you tried running your code using CRuby?

ioquatix · 2019-10-25T08:45:37Z

jruby/jruby#5944 is blocking this issue.

rdubya · 2019-10-30T21:03:14Z

Awesome. Thanks for digging into it.
