[Sbcl-devel] SBCL hangs when read-line from process-pty blocks

[Jianshi H. <jia...@gm...>]

Hi,

I'm debugging a ssh remote command from SBCL.

When I did (read-line (sb-ext:process-pty process)), and if it blocks,
then there's no way for me to stop it (e.g. ctrl-c, kill -INT pid also
doesn't work). What is the problem and is there anyway to fix it?

Example code:

(setf p (sb-ext:run-program "/usr/bin/ssh" '("-t" "remote-machine"
"cat") :wait nil :pty t))
(read-line (sb-ext:process-pty p))


Cheers,
