![]() ![]() function file that tests the deprecated function. In the function’s unit tests (see the test guidelines for more information on unit tests):Īdd MBEDTLS_TEST_DEPRECATED to the depends_on: line in the. See the ChangeLog readme for more information on the format of ChangeLog entries. ChangeLog.d/change-xyz-api.txt)Īdd an entry under the heading New deprecations that describes the deprecation. Typically this means refactoring the old function to be a simple wrapper around the new function. If the function is superseded, ensure there is no code duplication between the old function and the new one. Surround the function definition with #if !defined(MBEDTLS_DEPRECATED_REMOVED). ![]() Make sure the header file includes mbedtls/platform_util.h (this contains the definition of MBEDTLS_DEPRECATED). ![]() Surround the function declaration with #if !defined(MBEDTLS_DEPRECATED_REMOVED).Īdd a line to the docstring consisting of the keyword \deprecated followed by the reason for deprecation and (where applicable) the function it is superseded by.Īdd the MBEDTLS_DEPRECATED annotation to the function prototype (so int foo() becomes int MBEDTLS_DEPRECATED foo() ). To deprecate a function, the following actions must be taken: To find examples of past deprecations, look at the previous major version of Mbed TLS. Note: this only works when using GCC-like compilers that recognize _attribute_((deprecated)). When a build is made with MBEDTLS_DEPRECATED_WARNING defined, a compiler warning will be generated to warn a user that a function or constant will be removed at some point in the future, notifying users that they should change to a replacement function or constant at their own convenience. Instead, they may be ‘deprecated’, indicating to users that they will be removed in the future. To ensure backwards-compatibility between versions of Mbed TLS, elements of the public interface may not be removed except during the release of a new major version.
