"""
Test Mbed TLS with a subset of algorithms.
This script can be divided into several steps:
First, include/mbedtls/mbedtls_config.h or a different config file passed
in the arguments is parsed to extract any configuration options (using config.py).
Then, test domains (groups of jobs, tests) are built based on predefined data
collected in the DomainData class. Here, each domain has five major traits:
- domain name, can be used to run only specific tests via command-line;
- configuration building method, described in detail below;
- list of symbols passed to the configuration building method;
- commands to be run on each job (only build, build and test, or any other custom);
- optional list of symbols to be excluded from testing.
The configuration building method can be one of the three following:
- ComplementaryDomain - build a job for each passed symbol by disabling a single
symbol and its reverse dependencies (defined in REVERSE_DEPENDENCIES);
- ExclusiveDomain - build a job where, for each passed symbol, only this particular
one is defined and other symbols from the list are unset. For each job look for
any non-standard symbols to set/unset in EXCLUSIVE_GROUPS. These are usually not
direct dependencies, but rather non-trivial results of other configs missing. Then
look for any unset symbols and handle their reverse dependencies.
Examples of EXCLUSIVE_GROUPS usage:
- PSA_WANT_ALG_SHA_512 job turns off all hashes except SHA512. MBEDTLS_SSL_COOKIE_C
requires either SHA256 or SHA384 to work, so it also has to be disabled.
This is not a dependency on SHA512, but a result of an exclusive domain
config building method. Relevant field:
'PSA_WANT_ALG_SHA_512': ['-MBEDTLS_SSL_COOKIE_C'],
- DualDomain - combination of the two above - both complementary and exclusive domain
job generation code will be run. Currently only used for hashes.
Lastly, the collected jobs are executed and (optionally) tested, with
error reporting and coloring as configured in options. Each test starts with
a full config without a couple of slowing down or unnecessary options
(see set_reference_config), then the specific job config is derived.
