[lxc-devel] [PATCH] console API improvements

[Serge Hallyn]

Quoting Dwight Engen (dwight.engen at oracle.com):
> Add a higher level console API that opens a tty/console and runs the
> mainloop as well. Rename existing API to console_getfd(). Use these in
> the python binding.
> 
> Allow attaching a console peer after container bootup, including if the
> container was launched with -d. This is made possible by allocation of a
> "proxy" pty as the peer when the console is attached to.
> 
> Improve handling of SIGWINCH, the pty size will be correctly set at the
> beginning of a session and future changes when using the lxc_console() API
> will be propagated to it as well.

Hi,

we're hitting on black magic here as far as I'm concerned - but I can
verify that with this patch, 'sudo lxc-console -n container -t 0' gives
me the right size (per stty -a) on console which never happened before.
However, if I then resize my xterm, I have to disconnect and reconnect
the console to get the new size.  Is that expected?
