Re: using Copas with LuaSec, non-blocking ssl

[Oliver Kroth <oliver.kroth@...>]

Thijs,

you are right. I found the same while implementing SSL with LuaSEC in my 
project.

Currently I am trying get LuaSec and Copas work together in a 
non-blocking fashion, which is not that easy as there are some more 
issues between the socket library and the Copas which make a 
non-blocking connect() not 100% reliable on some OS.
The LuaSec functions in between complicate this a little bit further:-)
