<p class="MsoNormal" style="margin-bottom:12.0pt">SocketBio makes a lot more sense now, and that might explain a different problem I had during my various attempts of SIGPIPE errors in the ssl writes. I'll look at the LoE of modifying _ssl, but I am not optimistic.
You might hear from me again on that subject. In the meantime, I assume I am doomed to use blocking sockets of some kind to get this working?<br>

2.7.2 Stackless 3.1b3 060516 (default, Oct 22 2012, 11:45:30) [GCC 4.5.2]<br>
Stacklesslib Unreleased version (1.0.4?)<br>
SleekXMPP 1.1.10<br>
OpenSSL 0.9.8<br>
<br>
I'm working on a project that requires SleekXMPP to run under Stackless. Sleek likes to make use of SSL and TLS, and everything seems good until Sleek calls do_handshake() on the SSLSocket and a call way down the C stack returns Errno 9 Bad file descriptor.
The problem is that SSL will return this if there's a cert trust problem, but I don't think that's the whole issue. It's possibly related to the fact that I wasn't able to use SocketBio, using a proxy object instead to get the _socket.socket inheritance that
_ssl.sslwrap seems to require. There's a note in the comments for patch_ssl() that mentions a modifed _ssl module that can wrap any object, not just _socket.socket, but I found no other reference. Sleek without Stackless and monkeypatching works flawlessly.
Has anyone had similar issues using Stackless with SSL? Possibly even with Sleek?<br>
