"""
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 (collect_config_symbols).
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:
- MBEDTLS_SHA256 job turns off all hashes except SHA256, however, when investigating
reverse dependencies, SHA224 is found to depend on SHA256, so it is disabled,
and then SHA256 is found to depend on SHA224, so it is also disabled. To handle
this, there's a field in EXCLUSIVE_GROUPS that states that in a SHA256 test SHA224
should also be enabled before processing reverse dependencies:
'MBEDTLS_SHA256_C': ['+MBEDTLS_SHA224_C']
- MBEDTLS_SHA512_C 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_C, but a result of an exclusive domain
config building method. Relevant field:
'MBEDTLS_SHA512_C': ['-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.
