v2.9.0

Fast DDS v2.9.0

This minor release includes several new features (new log macros to avoid conflicts with external libraries), behavior change (default memory management policy is no longer PREALLOCATED_MEMORY_MODE, enable by default Fast DDS Statistics module but only taking statistics metrics if the corresponding Statistics DataWriter is enabled), performance improvements, CI improvements (including address sanitizer jobs), and several bug fixes.

Mind that, even though this release is API compatible with previous v2.x versions, it is NOT ABI compatible with previous versions.
This means that applications upgrading Fast DDS to v2.9.0 will require recompilation, though not source code modification.

It is also advisable to regenerate the type support from the IDL files using Fast DDS-Gen v2.3.0.
Furthermore, if upgrading to v2.9.0, it is also recommended to upgrade Fast CDR to v1.0.26

New features

1. New log macros EPROSIMA_LOG_INFO, EPROSIMA_LOG_WARNING and EPROSIMA_LOG_ERROR (#3107)
2. Add ENABLE_OLD_LOG_MACROS CMake option to support disabling the compilation of previous log macros (#3107)

Behavior changes

1. Default memory management policy set to PREALLOCATED_WITH_REALLOC_MEMORY_MODE (#3108)
2. Statistics metrics are only calculated/accumulated when their corresponding DataWriter is enabled in Fast DDS Statistics Module (#3109, #3146)
3. Enable FASTDDS_STATISTICS CMake option by default (#3135)

Improvements

1. CI improvements
   1. Add address sanitizer job for Fast DDS library (#3084)
   2. Add address sanitizer job for Discovery Server test suite (#3084, #3070)
2. Upgrade Fast CDR submodule (#3143)

Fixes

1. Synchronization fixes:

   2. Fix recurring data races in test suite (#3103)
   3. Fix thread sanitizer job keeping Ubuntu 20.04 (#3145)
3. Other:
