Bug #130019 for Net-SSLeay: ssl_write_all() interacts poorly with EAGAIN

I confirmed recently that if ssl_write_all() is called over and over on a socket and the peer doesn’t read, then ssl_write_all() will block indefinitely. This applies even with a non-blocking socket--and it’s worse because in that case a tight write() loop happens. While ssl_write_all() is documented as a “blocking” function, it seems like this function’s behavior could be a bit more helpful for non-blocking sockets (and blocking sockets with a socket-level timeout set), which by their nature are expected to indicate when the write buffer is full. That said, it may be too risky of a change to apply to the existing function … in which case, would it work to create an ssl_write_all_nb() function that works as I describe? Thank you for your time. -Felipe Gasper Mississauga, Ontario
