From: Ricardo Martincoski Date: Thu, 29 Jun 2017 02:45:43 +0000 (-0300) Subject: support/testing: let pexpect write stdout to log X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e664c5f71c9614b991b13225809772eaea4a3dc5;p=buildroot.git support/testing: let pexpect write stdout to log When the parameter logfile is passed to spawn(), pexpect sends both stdin and stdout to the logfile and it creates a double echo effect. One way to avoid the double echo in the logfile would be to disable the echo on the terminal just after login ("stty -echo"), but double echo of user and password would remain. Instead of that, send only the stdout to the logfile using the logfile_read property.
