Ruby/OpenSSL bug?

[Nathaniel Talbott]

The following program hangs indefinitely, blocking the whole script. I would
expect it to gracefully return an error.

require 'webrick'
require 'net/https'

s = WEBrick::HTTPServer.new(:Port => 5555)

s.mount_proc("/") do |req, resp|
resp.body = "Hi"
end

t = Thread.new do
s.start
end

h = Net::HTTP.new('localhost', 5555)
h.use_ssl = true
h.head('/')

s.stop
t.join

Note calling #head on an HTTP object pointing at an SSL server does fine.
I'm running:

ruby 1.8.1 (2003-10-31) [i386-linux]

Please let me know if there's any more information I can provide. It would
be great if this could be fixed before the release of 1.8.1.

Thanks,


Nathaniel

Handshake of SSL needs exchange of some messages, but
SSLSocket#connect disables switch of thread because it is
implemented with C.

I don't understand whether it is safe to wrap SSL_connect
with TRAP_BEG and TRAP_END. I think that it's better to do
it experimentally after release of Ruby-1.8.1 than now.

Though I tried to test it, it didn't work ;)
However it enables to interrupt with Crtl-C.
Hmm, I try inspecting a little more.

Bummer. :(

I don't guess there's a non-blocking version of connect, eh?

Will this allow other threads to run? My problem is that I have a Webrick
server that needs to check if another site is up, and I don't want the whole
server blocking while it waits on the (possibly nonexistent) reply from the
site.

Thanks for looking in to this,


Nathaniel
