Description

« Hide

When sending an HTTP GET using JRuby-OpenSSL, the GET hangs more than half of the time.

Relevant stacktrace below:
/Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/protocol.rb:86:in `read': execution expired (Timeout::Error)
from /Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/http.rb:2223:in `read_body_0'
from /Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/http.rb:2184:in `read_body'
from /Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/http.rb:2209:in `body'
from /Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/http.rb:2148:in `reading_body'
from /Users/light/dev/oss/jruby/trunk/jruby/lib/ruby/1.8/net/http.rb:1061:in `request'

With SSL disabled on both the server and client, the request goes through with no problem whatsoever.

Also occurs on trunk as of now.

Possibly worth nothing that this happens when using rubyntlm to perform NTLM authentication.

Half the time sounds like a threading issue. Can you get a dump of threads when it's hanging (java dump, usually ctrl+| or ctrl+break) and maybe provide short server/client scripts that can reproduce it?

Sadly, I'm fairly confident that I no longer have the implementation that exacerbated this condition.

Evan, any more info on this one? Otherwise I'll close it for now since I can't reproduce it.

This is the same issue as ~~JRUBY-2597~~. The problem was that the SSLSocket was blocking on a read when there was still SSL data to process in buffers. It's been fixed on trunk now. There is a disabled performance test that can be run to make sure the performance is still good on those operations.
