# 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/mbedtls_config.h
#    * Makefile, library/Makefile, programs/Makefile, tests/Makefile,
#      programs/fuzz/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, in suitable versions for the
#     interoperability tests. The following are the official versions at the
#     time of writing:
#     * GNUTLS_{CLI,SERV} = 3.4.10
#     * GNUTLS_NEXT_{CLI,SERV} = 3.7.2
#     * OPENSSL = 1.0.2g (without Debian/Ubuntu patches)
#     * OPENSSL_NEXT = 3.1.2
# 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.
#
# The behavior on an error depends on whether --keep-going (alias -k)
# is in effect.
#  * Without --keep-going: the script stops on the first error without
#    cleaning up. This lets you work in the configuration of the failing
#    component.
#  * With --keep-going: the script runs all requested components and
#    reports failures at the end. In particular the script always cleans
#    up on exit.
#
# 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.
#      * component_release_XXX: tests that the CI should skip during PR testing.
#  * 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.
#
# Warning: due to the way bash detects errors, the failure of a command
# inside 'if' or '!' is not detected. Use the 'not' function instead of '!'.
#
# Each component is executed in a separate shell process. The component
# fails if any command in it returns a non-zero status.
#
# 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/mbedtls/mbedtls_config.h` from a backup made before running
#   the component.
# * Check out `Makefile`, `library/Makefile`, `programs/Makefile`,
#   `tests/Makefile` and `programs/fuzz/Makefile` from git.
#   This cleans up after an in-tree use of CMake.
#
# 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:
  -q|--quiet            Only output component names, and errors if any.
  -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.
     --append-outcome   Append to the outcome file (if used).
     --arm-none-eabi-gcc-prefix=<string>
                        Prefix for a cross-compiler for arm-none-eabi

                        explicitly specified.
     --error-test       Error test mode: run a failing function in addition
                        to any specified component. May be repeated.
     --except           Exclude the COMPONENTs listed on the command line,
                        instead of running only those.

#### Helpers for components using libtestdriver1
################################################################

# How to use libtestdriver1
# -------------------------
#
# 1. Define the list algorithms and key types to accelerate,
#    designated the same way as PSA_WANT_ macros but without PSA_WANT_.
#    Examples:
#      - loc_accel_list="ALG_JPAKE"
#      - loc_accel_list="ALG_FFDH KEY_TYPE_DH_KEY_PAIR KEY_TYPE_DH_PUBLIC_KEY"
# 2. Make configurations changes for the driver and/or main libraries.
#    2a. Call helper_libtestdriver1_adjust_config <base>, where the argument
#        can be either "default" to start with the default config, or a name
#        supported by scripts/config.py (for example, "full"). This selects
#        the base to use, and makes common adjustments.
#    2b. If desired, adjust the PSA_WANT symbols in psa/crypto_config.h.
#        These changes affect both the driver and the main libraries.
#        (Note: they need to have the same set of PSA_WANT symbols, as that
#        determines the ABI between them.)
#    2c. Adjust MBEDTLS_ symbols in mbedtls_config.h. This only affects the
#        main libraries. Typically, you want to disable the module(s) that are
#        being accelerated. You may need to also disable modules that depend
#        on them or options that are not supported with drivers.
#    2d. On top of psa/crypto_config.h, the driver library uses its own config
#        file: tests/include/test/drivers/config_test_driver.h. You usually
#        don't need to edit it: using loc_extra_list (see below) is preferred.
#        However, when there's no PSA symbol for what you want to enable,
#        calling scripts/config.py on this file remains the only option.
# 3. Build the driver library, then the main libraries, test, and programs.
#    3a. Call helper_libtestdriver1_make_drivers "$loc_accel_list". You may
#        need to enable more algorithms here, typically hash algorithms when
#        accelerating some signature algorithms (ECDSA, RSAv2). This is done
#        by passing a 2nd argument listing the extra algorithms.
#        Example:
#          loc_extra_list="ALG_SHA_224 ALG_SHA_256 ALG_SHA_384 ALG_SHA_512"
#          helper_libtestdriver1_make_drivers "$loc_accel_list" "$loc_extra_list"
#    3b. Call helper_libtestdriver1_make_main "$loc_accel_list". Any
#        additional arguments will be passed to make: this can be useful if
#        you don't want to build everything when iterating during development.
#        Example:
#          helper_libtestdriver1_make_main "$loc_accel_list" -C tests test_suite_foo
# 4. Run the tests you want.

# Adjust the configuration - for both libtestdriver1 and main library,
# as they should have the same PSA_WANT macros.
helper_libtestdriver1_adjust_config() {
    base_config=$1
    # Select the base configuration
    if [ "$base_config" != "default" ]; then
        scripts/config.py "$base_config"

    # Enable PSA-based config (necessary to use drivers)
    scripts/config.py set MBEDTLS_PSA_CRYPTO_CONFIG

    # Dynamic secure element support is a deprecated feature and needs to be disabled here.
    # This is done to have the same form of psa_key_attributes_s for libdriver and library.
    scripts/config.py unset MBEDTLS_PSA_CRYPTO_SE_C

    # If threading is enabled on the normal build, then we need to enable it in the drivers as well,
    # otherwise we will end up running multithreaded tests without mutexes to protect them.

    # Most of the time, use of legacy MBEDTLS_xxx macros are mistakes, which
    # this component is meant to catch. However a few of them are justified,
    # mostly by the absence of a PSA equivalent, so this component includes a
    # list of expected exceptions.
