net-http-persistent incompatible with vcr/fakeweb when reuse_ssl_sessions==true

[mattbrictson]

By default, net-http-persistent has the option reuse_ssl_sessions = true, which causes Net::HTTP::Persistent::SSLReuse to be used as the underlying http class, rather than Net::HTTP. SSLReuse redefines connect to use the socket layer directly. The first line is:

s = timeout(@open_timeout) { TCPSocket.open(conn_address(), conn_port()) }

This apparently breaks higher level http mocking libraries. For example, when using the vcr gem with fakeweb mocking, I expect vcr to replay a previously recorded http interaction. Instead, I get an error like this:

Net::HTTP::Persistent::Error:
connection refused

Currently, my workaround is to prevent net-http-persistent from using the SSLReuse class during tests.

http = Net::HTTP::Persistent.new
# Disable SSL pool in test environment, as it breaks fakeweb
http.reuse_ssl_sessions = false if Rails.env.test?

Perhaps this there is no other way around this, but I thought I should at least document the problem here, as a Google search did not turn up any other explanations.

Another me too, adding work around for mechanize

agent = Mechanize.new
agent.agent.http.reuse_ssl_sessions = false

I'll need to add code to detect if fakeweb is active to disable SSL session reuse automatically, but it'll have to wait until after the mechanize bugfix release.
