Steven Rostedt 4e7d2a8f0b ktest.pl: Add RUN_TIMEOUT option with default unlimited
There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.

Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".

But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

#
# Config file for ktest.pl
#
# Place your customized version of this, in the working directory that
# ktest.pl is run from. By default, ktest.pl will look for a file
# called "ktest.conf", but you can name it anything you like and specify
# the name of your config file as the first argument of ktest.pl.
#
# Note, all paths must be absolute
#
# Options set in the beginning of the file are considered to be
# default options. These options can be overridden by test specific
# options, with the following exceptions:
#
# LOG_FILE
# CLEAR_LOG
# POWEROFF_ON_SUCCESS
# REBOOT_ON_SUCCESS
#
# Test specific options are set after the label:
#
# TEST_START
#
# The options after a TEST_START label are specific to that test.
# Each TEST_START label will set up a new test. If you want to
# perform a test more than once, you can add the ITERATE label
# to it followed by the number of times you want that test
# to iterate. If the ITERATE is left off, the test will only
# be performed once.
#
# TEST_START ITERATE 10
#
# You can skip a test by adding SKIP (before or after the ITERATE
# and number)
#
# TEST_START SKIP
#
# TEST_START SKIP ITERATE 10
#
# TEST_START ITERATE 10 SKIP
#
# The SKIP label causes the options and the test itself to be ignored.
# This is useful to set up several different tests in one config file, and
# only enabling the ones you want to use for a current test run.
#
# You can add default options anywhere in the file as well
# with the DEFAULTS tag. This allows you to have default options
# after the test options to keep the test options at the top
# of the file. You can even place the DEFAULTS tag between
# test cases (but not in the middle of a single test case)
#
# TEST_START
# MIN_CONFIG = /home/test/config-test1
#
# DEFAULTS
# MIN_CONFIG = /home/test/config-default
#
# TEST_START ITERATE 10
#
# The above will run the first test with MIN_CONFIG set to
# /home/test/config-test-1. Then 10 tests will be executed
# with MIN_CONFIG with /home/test/config-default.
#
# You can also disable defaults with the SKIP option
#
# DEFAULTS SKIP
# MIN_CONFIG = /home/test/config-use-sometimes
#
# DEFAULTS
# MIN_CONFIG = /home/test/config-most-times
#
# The above will ignore the first MIN_CONFIG. If you want to
# use the first MIN_CONFIG, remove the SKIP from the first
# DEFAULTS tag and add it to the second. Be careful, options
# may only be declared once per test or default. If you have
# the same option name under the same test or as default
# ktest will fail to execute, and no tests will run.
#
# DEFAULTS OVERRIDE
#
# Options defined in the DEFAULTS section can not be duplicated
# even if they are defined in two different DEFAULT sections.
# This is done to catch mistakes where an option is added but
# the previous option was forgotten about and not commented.
#
# The OVERRIDE keyword can be added to a section to allow this
# section to override other DEFAULT sections values that have
# been defined previously. It will only override options that
# have been defined before its use. Options defined later
# in a non override section will still error. The same option
# can not be defined in the same section even if that section
# is marked OVERRIDE.
#
#
#
# Both TEST_START and DEFAULTS sections can also have the IF keyword
# The value after the IF must evaluate into a 0 or non 0 positive
# integer, and can use the config variables (explained below).
#
# DEFAULTS IF ${IS_X86_32}
#
# The above will process the DEFAULTS section if the config
# variable IS_X86_32 evaluates to a non zero positive integer
# otherwise if it evaluates to zero, it will act the same
# as if the SKIP keyword was used.
#
# The ELSE keyword can be used directly after a section with
# a IF statement.
#
# TEST_START IF ${RUN_NET_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
#
# ELSE
#
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-normal
#
#
# The ELSE keyword can also contain an IF statement to allow multiple
# if then else sections. But all the sections must be either
# DEFAULT or TEST_START, they can not be a mixture.
#
# TEST_START IF ${RUN_NET_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
#
# ELSE IF ${RUN_DISK_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-tests
#
# ELSE IF ${RUN_CPU_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu
#
# ELSE
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
#
# The if statement may also have comparisons that will and for
# == and !=, strings may be used for both sides.
#
# BOX_TYPE := x86_32
#
# DEFAULTS IF ${BOX_TYPE} == x86_32
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-32
# ELSE
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-64
#
# The DEFINED keyword can be used by the IF statements too.
# It returns true if the given config variable or option has been defined
# or false otherwise.
#
#
# DEFAULTS IF DEFINED USE_CC
# CC := ${USE_CC}
# ELSE
# CC := gcc
#
#
# As well as NOT DEFINED.
#
# DEFAULTS IF NOT DEFINED MAKE_CMD
# MAKE_CMD := make ARCH=x86
#
#
# And/or ops (&&,||) may also be used to make complex conditionals.
#
# TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf
#
# Notice the use of parentheses. Without any parentheses the above would be
# processed the same as:
#
# TEST_START IF DEFINED ALL_TESTS || (${MYTEST} == boottest && ${MACHINE} == gandalf)
#
#
#
# INCLUDE file
#
# The INCLUDE keyword may be used in DEFAULT sections. This will
# read another config file and process that file as well. The included
# file can include other files, add new test cases or default
# statements. Config variables will be passed to these files and changes
# to config variables will be seen by top level config files. Including
# a file is processed just like the contents of the file was cut and pasted
# into the top level file, except, that include files that end with
# TEST_START sections will have that section ended at the end of
# the include file. That is, an included file is included followed
# by another DEFAULT keyword.
#
# Unlike other files referenced in this config, the file path does not need
# to be absolute. If the file does not start with '/', then the directory
# that the current config file was located in is used. If no config by the
# given name is found there, then the current directory is searched.
#
# INCLUDE myfile
# DEFAULT
#
# is the same as:
#
# INCLUDE myfile
#
# Note, if the include file does not contain a full path, the file is
# searched first by the location of the original include file, and then
# by the location that ktest.pl was executed in.
#
#### Config variables ####
#
# This config file can also contain "config variables".
# These are assigned with ":=" instead of the ktest option
# assignment "=".
#
# The difference between ktest options and config variables
# is that config variables can be used multiple times,
# where each instance will override the previous instance.
# And that they only live at time of processing this config.
#
# The advantage to config variables are that they can be used
# by any option or any other config variables to define thing
# that you may use over and over again in the options.
#
# For example:
#
# USER := root
# TARGET := mybox
# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test
#
# TEST_START
# MIN_CONFIG = config1
# TEST = ${TEST_CASE}
#
# TEST_START
# MIN_CONFIG = config2
# TEST = ${TEST_CASE}
#
# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2
#
# TEST_START
# MIN_CONFIG = config1
# TEST = ${TEST_CASE}
#
# TEST_START
# MIN_CONFIG = config2
# TEST = ${TEST_CASE}
#
# TEST_DIR := /home/me/test
#
# BUILD_DIR = ${TEST_DIR}/linux.git
# OUTPUT_DIR = ${TEST_DIR}/test
#
# Note, the config variables are evaluated immediately, thus
# updating TARGET after TEST_CASE has been assigned does nothing
# to TEST_CASE.
#
# As shown in the example, to evaluate a config variable, you
# use the ${X} convention. Simple $X will not work.
#
# If the config variable does not exist, the ${X} will not
# be evaluated. Thus:
#
# MAKE_CMD = PATH=/mypath:${PATH} make
#
# If PATH is not a config variable, then the ${PATH} in
# the MAKE_CMD option will be evaluated by the shell when
# the MAKE_CMD option is passed into shell processing.
#
# Shell commands can also be inserted with the ${shell <command>}
# expression. Note, this is case sensitive, thus ${SHELL <command>}
# will not work.
#
# HOSTNAME := ${shell hostname}
# DEFAULTS IF "${HOSTNAME}" == "frodo"
#
#### Using options in other options ####
#
# Options that are defined in the config file may also be used
# by other options. All options are evaluated at time of
# use (except that config variables are evaluated at config
# processing time).
#
# If an ktest option is used within another option, instead of
# typing it again in that option you can simply use the option
# just like you can config variables.
#
# MACHINE = mybox
#
# TEST = ssh root@${MACHINE} /path/to/test
#
# The option will be used per test case. Thus:
#
# TEST_TYPE = test
# TEST = ssh root@{MACHINE}
#
# TEST_START
# MACHINE = box1
#
# TEST_START
# MACHINE = box2
#
# For both test cases, MACHINE will be evaluated at the time
# of the test case. The first test will run ssh root@box1
# and the second will run ssh root@box2.
#### Mandatory Default Options ####
# These options must be in the default section, although most
# may be overridden by test options.
# The machine hostname that you will test
#MACHINE = target
# The box is expected to have ssh on normal bootup, provide the user
# (most likely root, since you need privileged operations)
#SSH_USER = root
# The directory that contains the Linux source code
#BUILD_DIR = /home/test/linux.git
# The directory that the objects will be built
# (can not be same as BUILD_DIR)
#OUTPUT_DIR = /home/test/build/target
# The location of the compiled file to copy to the target
# (relative to OUTPUT_DIR)
#BUILD_TARGET = arch/x86/boot/bzImage
# The place to put your image on the test machine
#TARGET_IMAGE = /boot/vmlinuz-test

#
# Here is a digital loggers power switch example
#POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin@power/outlet?5=CCL'
#
# Here is an example to reboot a virtual box on the current host
# with the name "Guest".
#POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
# The script or command that reads the console
#
# If you use ttywatch server, something like the following would work.
#CONSOLE = nc -d localhost 3001
#
# For a virtual machine with guest name "Guest".
#CONSOLE = virsh console Guest
# Signal to send to kill console.
# ktest.pl will create a child process to monitor the console.
# When the console is finished, ktest will kill the child process

# For REBOOT_TYPE = grub2, you must specify where the grub.cfg
# file is. This is the file that is searched to find the menu
# option to boot to with GRUB_REBOOT

#GRUB_REBOOT = grub2_reboot
# The grub title name for the test kernel to boot
# (Only mandatory if REBOOT_TYPE = grub or grub2 or grub2bls)
#
# Note, ktest.pl will not update the grub menu.lst, you need to
# manually add an option for the test. ktest.pl will search
# the grub menu.lst for this option to find what kernel to
# reboot into.
#
# For example, if in the /boot/grub/menu.lst the test kernel title has:
# title Test Kernel
# kernel vmlinuz-test
#
# For grub2, a search of top level "menuentry"s are done. No
# submenu is searched. The menu is found by searching for the
# contents of GRUB_MENU in the line that starts with "menuentry".
# You may want to include the quotes around the option. For example:
# for: menuentry 'Test Kernel'
# do a: GRUB_MENU = 'Test Kernel'
# For customizing, add your entry in /etc/grub.d/40_custom.
#
# For grub2bls, a search of "title"s are done. The menu is found
# by searching for the contents of GRUB_MENU in the line that starts
# with "title".

# Way to reboot the box to the test kernel.

# and select that target to reboot to the kernel. If this is not
# your setup, then specify "script" and have a command or script
# specified in REBOOT_SCRIPT to boot to the target.
#
# For REBOOT_TYPE = grub2, you must define both GRUB_MENU and
# GRUB_FILE.
#
# For REBOOT_TYPE = grub2bls, you must define GRUB_MENU.
#
# For REBOOT_TYPE = syslinux, you must define SYSLINUX_LABEL, and

# (default undefined)
#SWITCH_TO_GOOD = ssh ${SSH_USER}/${MACHINE} cp good_image ${TARGET_IMAGE}
# The min config that is needed to build for the machine
# A nice way to create this is with the following:

# $ rm .config
# $ make LSMOD=mymods localyesconfig
# $ grep '^CONFIG' .config > /home/test/config-min

# repeat the above several times
#
# # lsmod > mymods

#

#### Per test run options ####
# The following options are only allowed in TEST_START sections.
# They are ignored in the DEFAULTS sections.
#
# All of these are optional and undefined by default, although
# some of these options are required for TEST_TYPE of patchcheck
# and bisect.
#
#
# CHECKOUT = branch
#
# If the BUILD_DIR is a git repository, then you can set this option
# to checkout the given branch before running the TEST. If you
# specify this for the first run, that branch will be used for
# all preceding tests until a new CHECKOUT is set.
#
#
# TEST_NAME = name
#
# If you want the test to have a name that is displayed in
# the test result banner at the end of the test, then use this
# option. This is useful to search for the RESULT keyword and
# not have to translate a test number to a test in the config.
#
# For TEST_TYPE = patchcheck
#
# This expects the BUILD_DIR to be a git repository, and
# will checkout the PATCHCHECK_START commit.
#
# The option BUILD_TYPE will be ignored.
#
# The MIN_CONFIG will be used for all builds of the patchcheck. The build type
# used for patchcheck is oldconfig.
#
# PATCHCHECK_START is required and is the first patch to
# test (the SHA1 of the commit). You may also specify anything
# that git checkout allows (branch name, tag, HEAD~3).
#
# PATCHCHECK_END is the last patch to check (default HEAD)
#
# PATCHCHECK_CHERRY if set to non zero, then git cherry will be
# performed against PATCHCHECK_START and PATCHCHECK_END. That is
#
# git cherry ${PATCHCHECK_START} ${PATCHCHECK_END}
#
# Then the changes found will be tested.
#
# Note, PATCHCHECK_CHERRY requires PATCHCHECK_END to be defined.
# (default 0)
#
# PATCHCHECK_TYPE is required and is the type of test to run:
# build, boot, test.
#
# Note, the build test will look for warnings, if a warning occurred
# in a file that a commit touches, the build will fail, unless
# IGNORE_WARNINGS is set for the given commit's sha1
#
# IGNORE_WARNINGS can be used to disable the failure of patchcheck
# on a particular commit (SHA1). You can add more than one commit
# by adding a list of SHA1s that are space delimited.
#
# If BUILD_NOCLEAN is set, then make mrproper will not be run on
# any of the builds, just like all other TEST_TYPE tests. But
# what makes patchcheck different from the other tests, is if
# BUILD_NOCLEAN is not set, only the first and last patch run
# make mrproper. This helps speed up the test.
#
# Example:
# TEST_START
# TEST_TYPE = patchcheck
# CHECKOUT = mybranch
# PATCHCHECK_TYPE = boot
# PATCHCHECK_START = 747e94ae3d1b4c9bf5380e569f614eb9040b79e7
# PATCHCHECK_END = HEAD~2
# IGNORE_WARNINGS = 42f9c6b69b54946ffc0515f57d01dc7f5c0e4712 0c17ca2c7187f431d8ffc79e81addc730f33d128
#
#
#
# For TEST_TYPE = bisect
#
# You can specify a git bisect if the BUILD_DIR is a git repository.
# The MIN_CONFIG will be used for all builds of the bisect. The build type
# used for bisecting is oldconfig.
#
# The option BUILD_TYPE will be ignored.
#
# BISECT_TYPE is the type of test to perform:
# build - bad fails to build
# boot - bad builds but fails to boot
# test - bad boots but fails a test
#
# BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
# BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
#
# The above three options are required for a bisect operation.
#
# BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
#
# If an operation failed in the bisect that was not expected to
# fail. Then the test ends. The state of the BUILD_DIR will be
# left off at where the failure occurred. You can examine the
# reason for the failure, and perhaps even find a git commit
# that would work to continue with. You can run:
#
# git bisect log > /path/to/replay/file
#
# The adding:
#
# BISECT_REPLAY= /path/to/replay/file
#
# And running the test again. The test will perform the initial
# git bisect start, git bisect good, and git bisect bad, and
# then it will run git bisect replay on this file, before
# continuing with the bisect.
#
# BISECT_START = commit (optional, default undefined)
#
# As with BISECT_REPLAY, if the test failed on a commit that
# just happen to have a bad commit in the middle of the bisect,
# and you need to skip it. If BISECT_START is defined, it
# will checkout that commit after doing the initial git bisect start,
# git bisect good, git bisect bad, and running the git bisect replay
# if the BISECT_REPLAY is set.
#
# BISECT_SKIP = 1 (optional, default 0)
#
# If BISECT_TYPE is set to test but the build fails, ktest will
# simply fail the test and end their. You could use BISECT_REPLAY
# and BISECT_START to resume after you found a new starting point,
# or you could set BISECT_SKIP to 1. If BISECT_SKIP is set to 1,
# when something other than the BISECT_TYPE fails, ktest.pl will
# run "git bisect skip" and try again.
#
# BISECT_FILES = <path> (optional, default undefined)
#
# To just run the git bisect on a specific path, set BISECT_FILES.
# For example:
#
# BISECT_FILES = arch/x86 kernel/time
#
# Will run the bisect with "git bisect start -- arch/x86 kernel/time"
#
# BISECT_REVERSE = 1 (optional, default 0)
#
# In those strange instances where it was broken forever
# and you are trying to find where it started to work!
# Set BISECT_GOOD to the commit that was last known to fail
# Set BISECT_BAD to the commit that is known to start working.
# With BISECT_REVERSE = 1, The test will consider failures as
# good, and success as bad.
#
# BISECT_MANUAL = 1 (optional, default 0)
#
# In case there's a problem with automating the bisect for
# whatever reason. (Can't reboot, want to inspect each iteration)
# Doing a BISECT_MANUAL will have the test wait for you to
# tell it if the test passed or failed after each iteration.
# This is basically the same as running git bisect yourself
# but ktest will rebuild and install the kernel for you.
#
# BISECT_CHECK = 1 (optional, default 0)
#
# Just to be sure the good is good and bad is bad, setting
# BISECT_CHECK to 1 will start the bisect by first checking
# out BISECT_BAD and makes sure it fails, then it will check
# out BISECT_GOOD and makes sure it succeeds before starting
# the bisect (it works for BISECT_REVERSE too).
#
# You can limit the test to just check BISECT_GOOD or
# BISECT_BAD with BISECT_CHECK = good or
# BISECT_CHECK = bad, respectively.
#
# BISECT_TRIES = 5 (optional, default 1)
#
# For those cases that it takes several tries to hit a bug,
# the BISECT_TRIES is useful. It is the number of times the
# test is ran before it says the kernel is good. The first failure
# will stop trying and mark the current SHA1 as bad.
#
# Note, as with all race bugs, there's no guarantee that if
# it succeeds, it is really a good bisect. But it helps in case
# the bug is some what reliable.
#
# You can set BISECT_TRIES to zero, and all tests will be considered
# good, unless you also set BISECT_MANUAL.
#
# BISECT_RET_GOOD = 0 (optional, default undefined)
#
# In case the specificed test returns something other than just
# 0 for good, and non-zero for bad, you can override 0 being
# good by defining BISECT_RET_GOOD.
#
# BISECT_RET_BAD = 1 (optional, default undefined)
#
# In case the specificed test returns something other than just
# 0 for good, and non-zero for bad, you can override non-zero being
# bad by defining BISECT_RET_BAD.
#
# BISECT_RET_ABORT = 255 (optional, default undefined)
#
# If you need to abort the bisect if the test discovers something
# that was wrong, you can define BISECT_RET_ABORT to be the error
# code returned by the test in order to abort the bisect.
#
# BISECT_RET_SKIP = 2 (optional, default undefined)
#
# If the test detects that the current commit is neither good
# nor bad, but something else happened (another bug detected)
# you can specify BISECT_RET_SKIP to an error code that the
# test returns when it should skip the current commit.
#
# BISECT_RET_DEFAULT = good (optional, default undefined)
#
# You can override the default of what to do when the above
# options are not hit. This may be one of, "good", "bad",
# "abort" or "skip" (without the quotes).
#
# Note, if you do not define any of the previous BISECT_RET_*
# and define BISECT_RET_DEFAULT, all bisects results will do
# what the BISECT_RET_DEFAULT has.
#
#
# Example:
# TEST_START
# TEST_TYPE = bisect
# BISECT_GOOD = v2.6.36
# BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
# BISECT_TYPE = build
# MIN_CONFIG = /home/test/config-bisect
#
#
#
# For TEST_TYPE = config_bisect
#
# In those cases that you have two different configs. One of them
# work, the other does not, and you do not know what config causes
# the problem.
# The TEST_TYPE config_bisect will bisect the bad config looking for
# what config causes the failure.
#
# The way it works is this:
#
# You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
# will use the MIN_CONFIG, and if that's not specified, it will use
# the config that comes with "make defconfig".
#
# It runs both the good and bad configs through a make oldconfig to
# make sure that they are set up for the kernel that is checked out.
#
# It then reads the configs that are set, as well as the ones that are
# not set for both the good and bad configs, and then compares them.
# It will set half of the good configs within the bad config (note,
# "set" means to make the bad config match the good config, a config
# in the good config that is off, will be turned off in the bad
# config. That is considered a "set").
#
# It tests this new config and if it works, it becomes the new good
# config, otherwise it becomes the new bad config. It continues this
# process until there's only one config left and it will report that
# config.
#
# The "bad config" can also be a config that is needed to boot but was
# disabled because it depended on something that wasn't set.
#
# During this process, it saves the current good and bad configs in
# ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
# If you stop the test, you can copy them to a new location to
# reuse them again.
#
# Although the MIN_CONFIG may be the config it starts with, the
# MIN_CONFIG is ignored.
#
# The option BUILD_TYPE will be ignored.
#
# CONFIG_BISECT_TYPE is the type of test to perform:
# build - bad fails to build
# boot - bad builds but fails to boot
# test - bad boots but fails a test
#
# CONFIG_BISECT is the config that failed to boot
#
# If BISECT_MANUAL is set, it will pause between iterations.
# This is useful to use just ktest.pl just for the config bisect.
# If you set it to build, it will run the bisect and you can
# control what happens in between iterations. It will ask you if
# the test succeeded or not and continue the config bisect.
#
# CONFIG_BISECT_GOOD (optional)
# If you have a good config to start with, then you
# can specify it with CONFIG_BISECT_GOOD. Otherwise
# the MIN_CONFIG is the base, if MIN_CONFIG is not set
# It will build a config with "make defconfig"
#
# CONFIG_BISECT_CHECK (optional)
# Set this to 1 if you want to confirm that the config ktest
# generates (the bad config with the min config) is still bad.
# It may be that the min config fixes what broke the bad config
# and the test will not return a result.
# Set it to "good" to test only the good config and set it
# to "bad" to only test the bad config.
#
# CONFIG_BISECT_EXEC (optional)
# The config bisect is a separate program that comes with ktest.pl.
# By default, it will look for:
# `pwd`/config-bisect.pl # the location ktest.pl was executed from.
# If it does not find it there, it will look for:
# `dirname <ktest.pl>`/config-bisect.pl # The directory that holds ktest.pl
# If it does not find it there, it will look for:
# ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl
# Setting CONFIG_BISECT_EXEC will override where it looks.
#
# Example:
# TEST_START
# TEST_TYPE = config_bisect
# CONFIG_BISECT_TYPE = build
# CONFIG_BISECT = /home/test/config-bad
# MIN_CONFIG = /home/test/config-min
# BISECT_MANUAL = 1
#
#
#
# For TEST_TYPE = make_min_config
#
# After doing a make localyesconfig, your kernel configuration may
# not be the most useful minimum configuration. Having a true minimum
# config that you can use against other configs is very useful if
# someone else has a config that breaks on your code. By only forcing
# those configurations that are truly required to boot your machine
# will give you less of a chance that one of your set configurations
# will make the bug go away. This will give you a better chance to
# be able to reproduce the reported bug matching the broken config.
#
# Note, this does take some time, and may require you to run the
# test over night, or perhaps over the weekend. But it also allows
# you to interrupt it, and gives you the current minimum config
# that was found till that time.
#
# Note, this test automatically assumes a BUILD_TYPE of oldconfig
# and its test type acts like boot.
# TODO: add a test version that makes the config do more than just
# boot, like having network access.
#
# To save time, the test does not just grab any option and test
# it. The Kconfig files are examined to determine the dependencies
# of the configs. If a config is chosen that depends on another
# config, that config will be checked first. By checking the
# parents first, we can eliminate whole groups of configs that
# may have been enabled.
#
# For example, if a USB device config is chosen and depends on CONFIG_USB,
# the CONFIG_USB will be tested before the device. If CONFIG_USB is
# found not to be needed, it, as well as all configs that depend on
# it, will be disabled and removed from the current min_config.
#
# OUTPUT_MIN_CONFIG is the path and filename of the file that will
# be created from the MIN_CONFIG. If you interrupt the test, set
# this file as your new min config, and use it to continue the test.
# This file does not need to exist on start of test.
# This file is not created until a config is found that can be removed.
# If this file exists, you will be prompted if you want to use it
# as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
# is not defined.
# (required field)
#
# START_MIN_CONFIG is the config to use to start the test with.
# you can set this as the same OUTPUT_MIN_CONFIG, but if you do
# the OUTPUT_MIN_CONFIG file must exist.
# (default MIN_CONFIG)
#
# IGNORE_CONFIG is used to specify a config file that has configs that
# you already know must be set. Configs are written here that have
# been tested and proved to be required. It is best to define this
# file if you intend on interrupting the test and running it where
# it left off. New configs that it finds will be written to this file
# and will not be tested again in later runs.
# (optional)
#
# MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
# test if the created config can just boot the machine. If this is
# set to 'test', then the TEST option must be defined and the created
# config will not only boot the target, but also make sure that the
# config lets the test succeed. This is useful to make sure the final
# config that is generated allows network activity (ssh).
# (optional)
#
# USE_OUTPUT_MIN_CONFIG set this to 1 if you do not want to be prompted
# about using the OUTPUT_MIN_CONFIG as the MIN_CONFIG as the starting
# point. Set it to 0 if you want to always just use the given MIN_CONFIG.
# If it is not defined, it will prompt you to pick which config
# to start with (MIN_CONFIG or OUTPUT_MIN_CONFIG).
#
# Example:
#
# TEST_TYPE = make_min_config
# OUTPUT_MIN_CONFIG = /path/to/config-new-min
# START_MIN_CONFIG = /path/to/config-min
# IGNORE_CONFIG = /path/to/config-tested
# MIN_CONFIG_TYPE = test
# TEST = ssh ${USER}@${MACHINE} echo hi
#
#
#
#
# For TEST_TYPE = make_warnings_file
#
# If you want the build to fail when a new warning is discovered
# you set the WARNINGS_FILE to point to a file of known warnings.
#
# The test "make_warnings_file" will let you create a new warnings
# file before you run other tests, like patchcheck.
#
# What this test does is to run just a build, you still need to
# specify BUILD_TYPE to tell the test what type of config to use.
# A BUILD_TYPE of nobuild will fail this test.
#
# The test will do the build and scan for all warnings. Any warning
# it discovers will be saved in the WARNINGS_FILE (required) option.
#
# It is recommended (but not necessary) to make sure BUILD_NOCLEAN is
# off, so that a full build is done (make mrproper is performed).
# That way, all warnings will be captured.
#
# Example:
#
# TEST_TYPE = make_warnings_file
# WARNINGS_FILE = ${OUTPUT_DIR}
# BUILD_TYPE = useconfig:oldconfig
# CHECKOUT = v3.8
# BUILD_NOCLEAN = 0
#
