I think we need to do more to encourage the use of the CommonRuby

Hi,

[#54211] Re: Encouraging use of CommonRuby — "NARUSE, Yui" <naruse@...> 2013/04/12

As far as I understand, what is CommonRuby and the process over CommonRuby

[ruby-core:54298] [ruby-trunk - Bug #7584] Ruby hangs when shutting down an ssl connection in gc finalization

From: "bpot (Bob Potter)" <bobby.potter@...>
Date: 2013-04-15 21:29:34 UTC
List: ruby-core #54298
Issue #7584 has been updated by bpot (Bob Potter).


Looks like that fixes it!  I was unable to reproduce with "ruby 2.1.0dev (2013-04-15 trunk 40308) [x86_64-linux]".

----------------------------------------
Bug #7584: Ruby hangs when shutting down an ssl connection in gc finalization
https://bugs.ruby-lang.org/issues/7584#change-38579

Author: bpot (Bob Potter)
Status: Assigned
Priority: Normal
Assignee: MartinBosslet (Martin Bosslet)
Category: ext
Target version: current: 2.1.0
ruby -v: ruby 1.9.3p327 (2012-11-10) [i686-linux] 


It appears that during garbage collection ruby will sometimes attempt to shutdown an ssl connection that has already been shutdown. At least in certain cases this causes the SSL_shutdown call to block forever.

(gdb) bt

(gdb) p (*ssl).shutdown
$8 = 1

I'm not sure exactly what is causing this condition, but it seems like we should be checking if the connection is already shutdown (ssl_get_shutdown()) before trying to shut it down in ossl_ssl_free.
