This commit improves hygiene and formatting of macro definitions
throughout the library. Specifically:
- It adds brackets around parameters to avoid unintended
interpretation of arguments, e.g. due to operator precedence.
- It adds uses of the `do { ... } while( 0 )` idiom for macros that
can be used as commands.
requires_config_enabled doesn't support multiple config options.
Tests having multiple configuration dependencies must be prefixed
with multiple invocations of requires_config_enabled instead.
When doing ABI/API checking, its useful to have a list of all the
identifiers that are defined in the internal header files, as we
do not promise compatibility for them. This option allows for a
simple method of getting them for use with the ABI checking script.
There are a number of arguments being passed around, nearly all of
which are duplicated between the old and new versions. Moving these
into a separate class should hopefully make it simpler to follow
what is being done.
As before with wanting to compare revisions across different
repositories, the ability to select the crypto submodule from a
different repository is useful.
We may wish to compare ABI/API between Mbed TLS and Mbed Crypto,
which will cause issues as not all .so files are shared. Only
compare .so files which both libraries have.
As going forward we will have Crypto in a submodule, we will need to
be able to check ABI compatibility between versions using different
submodule versions. For TLS versions that support the submodule, we
will always build using the submodule.
If the Crypto submodule is used, libmbedcrypto.so is not in the main
library folder, but in crypto/library instead. Given this, the script
searches for *.so files and notes their path, in order to create the
dumps correctly.
By default abi-compliance-checker will check the entire ABI/API.
There are internal identifiers that we do not promise compatibility
for, so we want the ability to skip them when checking the ABI/API.
Without a "--detach" option, git worktree will refuse to checkout a branch
that's already checked out. This makes the abi_check.py script not very
useful for checking the currently checked out branch, as git will error
that the branch is already checked out. Add the "--detach" option to check
out the new temporary worktree in detached head mode. This is acceptable
because we aren't planning on working on the branch and just want a
checkout to do ABI checking from.
Run ssl-opt.sh on x86_32 with ASan. This may detect bugs that only
show up on 32-bit platforms, for example due to size_t overflow.
For this component, turn off some memory management features that are
not useful, potentially slow, and may reduce ASan's effectiveness at
catching buffer overflows.
