Is there a simple, easy to reuse, example of gnu-tls acting like a proxy which is truly non-blocking? By truly non-blocking I mean using non-blocking writes as well as non-blocking reads. The danger I am concerned about is receiving a large amount of plain-text, gnutls converting that to cypher-text, attempting to write it but blocking because the remote side is not ready to receive it. The remote side is not ready to receive it because it has its own output blocked as gnutls is not polling for reads as it's blocked above, meaning deadlock.
I've done this for OpenSSL, and it was a pain (frankly). I'd now like to do it for gnutls as I'd like to incorporate the result into a GPL project, and OpenSSL's licensing may be considered problematic. Therefore an example which is GPL / GPL-compatible would be great. Otherwise an example of how I could do it would be good. Something like stunnel written with gnutls would be ideal. Unless I'm missing something gnutls-cli only does non-blocking reads (not non-blocking writes). -- Alex Bligh _______________________________________________ Gnutls-help mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnutls-help
