From 5158ba3ea7fc8c3deafec769a32bc6eb869c3608 Mon Sep 17 00:00:00 2001 From: Russ Dill Date: Mon, 23 Apr 2012 19:43:00 -0700 Subject: [PATCH 1/2] ktest.pl: Fix combined usage of BISECT_REVERSE and BISECT_SKIP When BISECT_REVERSE and BISECT_SKIP are used together with boot or test testing, build failures are treated as boot or test failures and 'git bisect bad' is executed instead of 'git bisect skip'. This is because the $ret value of -1 is treated as a build failure, but the $reverse_bisect logic does not properly handle this. Simple fix, only invert it if it is positive.

The "no_reboot" variable was only cleared if the test had reboot_on_success set. But the no_reboot variable also prevents the test rebooting when an error was detected even when REBOOT_ON_ERROR was set. Add a new "reboot_success" variable that is used to determine if the test should reboot on success and not touch the no_reboot variable.
