From faa4c759b90a365e532321f18979812f9b6442eb Mon Sep 17 00:00:00 2001 From: Philip Hands Date: Fri, 3 Mar 2017 13:34:45 +0100 Subject: lvc: reinstate VMcommand's ability to run commands and get results This modifies the inittab to run a very simple loop on d-i's ttyS0 that reads commands from stdin, runs them and tops and tails the output with various control characters to make it easier to see when we have a result. It outputs a BEL (Ctrl-G, \a, \007) at the start, then an STX (\002) before running the command, and an ETX (\003) afterwards, to bracket STDOUT. After the ETX comes the command's return code, in decimal, then a US (\037), then comes the STDERR, and finally a NUL (\000) That lets us send an 'exit' and look for a BEL then issue a command and find the values required to populate the @returncode, @stdout and @stderr values. --- cucumber/features/step_definitions/common_steps.rb | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) (limited to 'cucumber/features/step_definitions') diff --git a/cucumber/features/step_definitions/common_steps.rb b/cucumber/features/step_definitions/common_steps.rb index 328c5661..6f47bb93 100644 --- a/cucumber/features/step_definitions/common_steps.rb +++ b/cucumber/features/step_definitions/common_steps.rb @@ -208,6 +208,11 @@ When /^I start the computer$/ do post_vm_start_hook end +When /^I execute "([^"]*)"$/ do |cmd| + info_log($vm.execute(cmd)) +end + + Given /^I start Tails( from DVD)?( with network unplugged)?( and I login)?$/ do |dvd_boot, network_unplugged, do_login| step "the computer is set to boot from the Tails DVD" if dvd_boot if network_unplugged.nil? @@ -289,7 +294,14 @@ Given /^I select the install mode$/ do @screen.type(Sikuli::Key.TAB) @boot_options = "" if @boot_options.nil? - @screen.type(' preseed/early_command="echo DPMS=-s\\\\ 0 > /lib/debian-installer.d/S61Xnoblank ; sed -i /XF86_Switch_VT_/s/F/XF86_Switch_VT_/ /usr/share/X11/xkb/symbols/srvr_ctrl ; echo ttyS0::askfirst:-/bin/sh>>/etc/inittab;kill -HUP 1" blacklist=psmouse ' + @boot_options + + initcmd = 'printf \\\\\\\\07; while read x; do printf \\\\\\\\02; eval $x 2>/tmp/.remcmd_stderr; printf \\\\\\\\03%%s\\\\\\\\037 $?; cat /tmp/.remcmd_stderr; printf \\\\\\\\00; done'.gsub(/([$\\;>])/, '\\\\\0') + inittab_line = ('ttyS0::respawn:-/bin/sh -c \\\\047' + initcmd + '\\\\047').gsub(/ /, '\\ ') + @screen.type( ' preseed/early_command="echo DPMS=-s\\\\ 0 > /lib/debian-installer.d/S61Xnoblank;' + + ' sed -i /XF86_Switch_VT_/s/F/XF86_Switch_VT_/ /usr/share/X11/xkb/symbols/srvr_ctrl;' + + ' set -x;' + + ' { printf ' + inittab_line + ';echo;}>>/etc/inittab;' + + ' kill -HUP 1" blacklist=psmouse ' + + @boot_options + Sikuli::Key.ENTER) debug_log("debug: wait for the remote shell to respond...", :color => :blue) $vm.wait_until_remote_shell_is_up -- cgit v1.2.3-70-g09d2
