#### Documentation
################################################################

# Purpose
# -------
#
# To run all tests possible or available on the platform.
#
# Notes for users
# ---------------
#
# Warning: the test is destructive. It includes various build modes and
# configurations, and can and will arbitrarily change the current CMake
# configuration. The following files must be committed into git:
#    * include/mbedtls/config.h
#    * Makefile, library/Makefile, programs/Makefile, tests/Makefile
# After running this script, the CMake cache will be lost and CMake
# will no longer be initialised.
#
# The script assumes the presence of a number of tools:
#   * Basic Unix tools (Windows users note: a Unix-style find must be before
#     the Windows find in the PATH)
#   * Perl
#   * GNU Make
#   * CMake
#   * GCC and Clang (recent enough for using ASan with gcc and MemSan with clang, or valgrind)
#   * G++
#   * arm-gcc and mingw-gcc
#   * ArmCC 5 and ArmCC 6, unless invoked with --no-armcc
#   * OpenSSL and GnuTLS command line tools, recent enough for the
#     interoperability tests. If they don't support SSLv3 then a legacy
#     version of these tools must be present as well (search for LEGACY
#     below).
# See the invocation of check_tools below for details.
#
# This script must be invoked from the toplevel directory of a git
# working copy of Mbed TLS.
#
# Note that the output is not saved. You may want to run
#   script -c tests/scripts/all.sh
# or
#   tests/scripts/all.sh >all.log 2>&1
#
# Notes for maintainers
# ---------------------
#
# The bulk of the code is organized into functions that follow one of the
# following naming conventions:
#  * pre_XXX: things to do before running the tests, in order.
#  * component_XXX: independent components. They can be run in any order.
#      * component_check_XXX: quick tests that aren't worth parallelizing.
#      * component_build_XXX: build things but don't run them.
#      * component_test_XXX: build and test.
#  * support_XXX: if support_XXX exists and returns false then
#    component_XXX is not run by default.
#  * post_XXX: things to do after running the tests.
#  * other: miscellaneous support functions.
#
# Each component must start by invoking `msg` with a short informative message.
#
# The framework performs some cleanup tasks after each component. This
# means that components can assume that the working directory is in a
# cleaned-up state, and don't need to perform the cleanup themselves.
# * Run `make clean`.
# * Restore `include/mbedtks/config.h` from a backup made before running
#   the component.
# * Check out `Makefile`, `library/Makefile`, `programs/Makefile` and
#   `tests/Makefile` from git. This cleans up after an in-tree use of
#   CMake.
#
# Any command that is expected to fail must be protected so that the
# script keeps running in --keep-going mode despite `set -e`. In keep-going
# mode, if a protected command fails, this is logged as a failure and the
# script will exit with a failure status once it has run all components.
# Commands can be protected in any of the following ways:
# * `make` is a function which runs the `make` command with protection.
#   Note that you must write `make VAR=value`, not `VAR=value make`,
#   because the `VAR=value make` syntax doesn't work with functions.
# * Put `report_status` before the command to protect it.
# * Put `if_build_successful` before a command. This protects it, and
#   additionally skips it if a prior invocation of `make` in the same
#   component failed.
#
# The tests are roughly in order from fastest to slowest. This doesn't
# have to be exact, but in general you should add slower tests towards
# the end and fast checks near the beginning.

Usage: $0 [OPTION]... [COMPONENT]...
Run mbedtls release validation tests.
By default, run all tests. With one or more COMPONENT, run only those.
COMPONENT can be the name of a component or a shell wildcard pattern.

Examples:
  $0 "check_*"
    Run all sanity checks.
  $0 --no-armcc --except test_memsan
    Run everything except builds that require armcc and MemSan.

Special options:
  -h|--help             Print this help and exit.
  --list-all-components List all available test components and exit.
  --list-components     List components supported on this platform and exit.

General options:
  -f|--force            Force the tests to overwrite any modified files.
  -k|--keep-going       Run all tests and report errors at the end.
  -m|--memory           Additional optional memory tests.
     --armcc            Run ARM Compiler builds (on by default).
     --except           Exclude the COMPONENTs listed on the command line,
                        instead of running only those.
     --no-armcc         Skip ARM Compiler builds.
     --no-force         Refuse to overwrite modified files (default).
     --no-keep-going    Stop at the first error (default).
     --no-memory        No additional memory tests (default).
     --out-of-source-dir=<path>  Directory used for CMake out-of-source build tests.
     --random-seed      Use a random seed value for randomized tests (default).
  -r|--release-test     Run this script in release mode. This fixes the seed value to 1.
  -s|--seed             Integer seed value to use for this test run.

Tool path options:
     --armc5-bin-dir=<ARMC5_bin_dir_path>       ARM Compiler 5 bin directory.
     --armc6-bin-dir=<ARMC6_bin_dir_path>       ARM Compiler 6 bin directory.
     --gnutls-cli=<GnuTLS_cli_path>             GnuTLS client executable to use for most tests.
     --gnutls-serv=<GnuTLS_serv_path>           GnuTLS server executable to use for most tests.
     --gnutls-legacy-cli=<GnuTLS_cli_path>      GnuTLS client executable to use for legacy tests.
     --gnutls-legacy-serv=<GnuTLS_serv_path>    GnuTLS server executable to use for legacy tests.
     --openssl=<OpenSSL_path>                   OpenSSL executable to use for most tests.
     --openssl-legacy=<OpenSSL_path>            OpenSSL executable to use for legacy tests e.g. SSLv3.
     --openssl-next=<OpenSSL_path>              OpenSSL executable to use for recent things like ARIA
