I tested further and the test fails deterministically at the same spot each time. If I rewrite test_write_nonblock as follows:

    def test_write_nonblock
      ssl_pair {|s1, s2|
      n = 0
      begin
        n += s1.write_nonblock("a" * 100000)
        n += s1.write_nonblock("b" * 100000)
        n += s1.write_nonblock("c" * 100000)
        100000.times do |i|
         n +=  1
         begin
           s1.write_nonblock("d")
         rescue OpenSSL::SSL::SSLError => e
           p e
           puts "Iteration: #{i}"
           raise e
         end
        end
        puts "Da5"
        n += s1.write_nonblock("e" * 100000)
        puts "Da6"
        n += s1.write_nonblock("f" * 100000)
        puts "Da7"
      rescue IO::WaitWritable
      end
      s1.close
      assert_equal(n, s2.read.length)
    }
  end

it will always yield the same result (only with Ubuntu's 0.9.8k though) when running make test-all TESTS="openssl/test_pair.rb":

..................#<OpenSSL::SSL::SSLError: write would block>
Iteration: 441
E.

20 tests, 101 assertions, 0 failures, 1 errors, 0 skips

It always flunks at iteration 441 with an "OpenSSL::SSL:SSLError: write would block".

Bug #4923: [ext/openssl] test_ssl.rb: test_client_auth fails
http://redmine.ruby-lang.org/issues/4923

Hi,

I was finally able to reproduce this with Fedora 15 32 bit, OpenSSL 1.0.0d.

The error occurs only when running make test-all TESTS="openssl",
if I run test_ssl.rb independently the test succeeds.

Here is the output I get:

1) Error:
test_client_auth(OpenSSL::TestSSL):
OpenSSL::SSL::SSLError: SSL_read:: sslv3 alert bad record mac
    /home/martin/Projekte/Ruby/build/.ext/common/openssl/buffering.rb:53:in `sysread'
    /home/martin/Projekte/Ruby/build/.ext/common/openssl/buffering.rb:53:in `fill_rbuff'
    /home/martin/Projekte/Ruby/build/.ext/common/openssl/buffering.rb:200:in `gets'
    /home/martin/Projekte/Ruby/ruby/test/openssl/test_ssl.rb:118:in `block in test_client_auth'
    /home/martin/Projekte/Ruby/ruby/test/openssl/utils.rb:280:in `call'
    /home/martin/Projekte/Ruby/ruby/test/openssl/utils.rb:280:in `start_server'
    /home/martin/Projekte/Ruby/ruby/test/openssl/test_ssl.rb:103:in `test_client_auth'

Related to #4919.

Regards,
Martin
