Subject: tls: more accurate wrapping of connecting socket
X-Git-Tag: v0.11.9~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6ddfe20d2bc256c71551b932a353d1b6491efd1;p=platform%2Fupstream%2Fnodejs.git

tls: more accurate wrapping of connecting socket

When socket, passed in `tls.connect()` `options` argument is not yet
connected to the server, `_handle` gets assigned to a `net.Socket`,
instead of `TLSSocket`.

When socket is connecting to the remote server (i.e. not yet connected,
but already past dns resolve phase), derive `_connecting` property from
it, because otherwise `afterConnect()` will throw an assertion.

fix #6443
