+
+# Purpose
+# -------
+#
+# To run all tests possible or available on the platform.
+#
+# Files structure
+# ---------------
+#
+# The executable entry point for users and the CI is tests/scripts/all.sh.
+#
+# The actual content is in the following files:
+# - all-core.sh contains the core logic for running test components,
+#   processing command line options, reporting results, etc.
+# - all-helpers.sh contains helper functions used by more than 1 component.
+# - components-*.sh contain the definitions of the various components.
+#
+# The first two parts are shared between repos and branches;
+# the component files are repo&branch-specific.
+#
+# The files all-*.sh and components-*.sh should only define functions and not
+# run code when sourced; the only exception being that all-core.sh runs
+# 'shopt' because that is necessary for the rest of the file to parse.
+#
+# 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 6 (aka armclang), 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:
+# * in all-core.sh:
+#   * pre_XXX: things to do before running the tests, in order.
+#   * post_XXX: things to do after running the tests.
+# * in components-*.sh:
+#   * 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.
+# * in various files:
+#   * 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 the various config files (potentially modified by config.py) from
+#   a backup made when starting the script.
+# * If in Mbed TLS, restore the various `Makefile`s (potentially modified by
+#   in-tree use of CMake) from a backup made when starting the script. (Note:
+#   if the files look generated when starting the script, they will be
+#   restored from the git index before making the backup.)

+                        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/configs/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

+"""
+This script confirms that the naming of all symbols and identifiers in Mbed TLS
+are consistent with the house style and are also self-consistent. It only runs
+on Linux and macOS since it depends on nm.
+
+It contains three major Python classes, TFPSACryptoCodeParser,
+MBEDTLSCodeParser and NameChecker. They all have a comprehensive "run-all"
+function (comprehensive_parse() and perform_checks()) but the individual
+functions can also be used for specific needs.
+
+CodeParser(a inherent base class for TFPSACryptoCodeParser and MBEDTLSCodeParser)
+makes heavy use of regular expressions to parse the code, and is dependent on
+the current code formatting. Many Python C parser libraries require
+preprocessed C code, which means no macro parsing. Compiler tools are also not
+very helpful when we want the exact location in the original source (which
+becomes impossible when e.g. comments are stripped).
+
+NameChecker performs the following checks:
+
+- All exported and available symbols in the library object files, are explicitly
+  declared in the header files. This uses the nm command.
+- All macros, constants, and identifiers (function names, struct names, etc)
+  follow the required regex pattern.
+- Typo checking: All words that begin with MBED|PSA exist as macros or constants.
+
+The script returns 0 on success, 1 on test failure, and 2 if there is a script
+error. It must be run from Mbed TLS root.

+"""Generate test data for bignum functions.
+
+With no arguments, generate all test data. With non-option arguments,
+generate only the specified files.
+
+Class structure:
+
+Child classes of test_data_generation.BaseTarget (file targets) represent an output
+file. These indicate where test cases will be written to, for all subclasses of
+this target. Multiple file targets should not reuse a `target_basename`.
+
+Each subclass derived from a file target can either be:
+  - A concrete class, representing a test function, which generates test cases.
+  - An abstract class containing shared methods and attributes, not associated
+        with a test function. An example is BignumOperation, which provides
+        common features used for bignum binary operations.
+
+Both concrete and abstract subclasses can be derived from, to implement
+additional test cases (see BignumCmp and BignumCmpAbs for examples of deriving
+from abstract and concrete classes).
+
+
+Adding test case generation for a function:
+
+A subclass representing the test function should be added, deriving from a
+file target such as BignumTarget. This test class must set/implement the
+following:
+  - test_function: the function name from the associated .function file.
+  - test_name: a descriptive name or brief summary to refer to the test
+        function.
+  - arguments(): a method to generate the list of arguments required for the
+        test_function.
+  - generate_function_tests(): a method to generate TestCases for the function.
+        This should create instances of the class with required input data, and
+        call `.create_test_case()` to yield the TestCase.
+
+Additional details and other attributes/methods are given in the documentation
+of BaseTarget in test_data_generation.py.

+This script is a key part of Mbed TLS test suites framework. For
+understanding the script it is important to understand the
+framework. This doc string contains a summary of the framework
+and explains the function of this script.
+
+Mbed TLS test suites:
+=====================
+Scope:
+------
+The test suites focus on unit testing the crypto primitives and also
+include x509 parser tests. Tests can be added to test any Mbed TLS
+module. However, the framework is not capable of testing SSL
+protocol, since that requires full stack execution and that is best
+tested as part of the system test.
+
+Test case definition:
+---------------------
+Tests are defined in a test_suite_<module>[.<optional sub module>].data
+file. A test definition contains:
+ test name
+ optional build macro dependencies
+ test function
+ test parameters
+
+Test dependencies are build macros that can be specified to indicate
+the build config in which the test is valid. For example if a test
+depends on a feature that is only enabled by defining a macro. Then
+that macro should be specified as a dependency of the test.
+
+Test function is the function that implements the test steps. This
+function is specified for different tests that perform same steps
+with different parameters.
+
+Test parameters are specified in string form separated by ':'.
+Parameters can be of type string, binary data specified as hex
+string and integer constants specified as integer, macro or
+as an expression. Following is an example test definition:
+
+ AES 128 GCM Encrypt and decrypt 8 bytes
+ depends_on:MBEDTLS_AES_C:MBEDTLS_GCM_C
+ enc_dec_buf:MBEDTLS_CIPHER_AES_128_GCM:"AES-128-GCM":128:8:-1
+
+Test functions:
+---------------
+Test functions are coded in C in test_suite_<module>.function files.
+Functions file is itself not compilable and contains special
+format patterns to specify test suite dependencies, start and end
+of functions and function dependencies. Check any existing functions
+file for example.
+
+Execution:
+----------
+Tests are executed in 3 steps:
+- Generating test_suite_<module>[.<optional sub module>].c file
+  for each corresponding .data file.
+- Building each source file into executables.
+- Running each executable and printing report.
+
+Generating C test source requires more than just the test functions.
+Following extras are required:
+- Process main()
+- Reading .data file and dispatching test cases.
+- Platform specific test case execution
+- Dependency checking
+- Integer expression evaluation
+- Test function dispatch
+
+Build dependencies and integer expressions (in the test parameters)
+are specified as strings in the .data file. Their run time value is
+not known at the generation stage. Hence, they need to be translated
+into run time evaluations. This script generates the run time checks
+for dependencies and integer expressions.
+
+Similarly, function names have to be translated into function calls.
+This script also generates code for function dispatch.
+
+The extra code mentioned here is either generated by this script
+or it comes from the input files: helpers file, platform file and
+the template file.
+
+Helper file:
+------------
+Helpers file contains common helper/utility functions and data.
+
+Platform file:
+--------------
+Platform file contains platform specific setup code and test case
+dispatch code. For example, host_test.function reads test data
+file from host's file system and dispatches tests.
+
+Template file:
+---------
+Template file for example main_test.function is a template C file in
+which generated code and code from input files is substituted to
+generate a compilable C file. It also contains skeleton functions for
+dependency checks, expression evaluation and function dispatch. These
+functions are populated with checks and return codes by this script.
+
+Template file contains "replacement" fields that are formatted
+strings processed by Python string.Template.substitute() method.
+
+This script:
+============
+Core function of this script is to fill the template file with
+code that is generated or read from helpers and platform files.
+
+This script replaces following fields in the template and generates
+the test source file:
+
+__MBEDTLS_TEST_TEMPLATE__TEST_COMMON_HELPERS
+            All common code from helpers.function
+            is substituted here.
+__MBEDTLS_TEST_TEMPLATE__FUNCTIONS_CODE
+            Test functions are substituted here
+            from the input test_suit_xyz.function
+            file. C preprocessor checks are generated
+            for the build dependencies specified
+            in the input file. This script also
+            generates wrappers for the test
+            functions with code to expand the
+            string parameters read from the data
+            file.
+__MBEDTLS_TEST_TEMPLATE__EXPRESSION_CODE
+            This script enumerates the
+            expressions in the .data file and
+            generates code to handle enumerated
+            expression Ids and return the values.
+__MBEDTLS_TEST_TEMPLATE__DEP_CHECK_CODE
+            This script enumerates all
+            build dependencies and generate
+            code to handle enumerated build
+            dependency Id and return status: if
+            the dependency is defined or not.
+__MBEDTLS_TEST_TEMPLATE__DISPATCH_CODE
+            This script enumerates the functions
+            specified in the input test data file
+            and generates the initializer for the
+            function table in the template
+            file.
+__MBEDTLS_TEST_TEMPLATE__PLATFORM_CODE
+            Platform specific setup and test
+            dispatch code.
