MySQL Router 8.0

This is a release of MySQL Router.

For the avoidance of doubt, this particular copy of the software is released under the version 2 of the GNU General Public License. MySQL Router is brought to you by Oracle.

Documentation

For further information about MySQL or additional documentation, see:

You can browse the MySQL Router Reference Manual online or download it in any of several formats at the URL given earlier in this file. Source distributions include a local copy of the manual in the Docs directory.

Developer documentation can be build when Doxygen 1.8.9 or greater has been installed:

shell> cd build
shell> cmake ..
shell> make doc

You can then open the folder doc/html/index.html in your browser.

Coverage information

To build so that coverage information is generated:

cmake <path-to-source> -DENABLE_COVERAGE=1

To get coverage information, just run the program or the unit tests (do not forget to enable the unit tests if you want to run them). Once you have collected coverage information, you can generate an HTML report in <build-dir>/coverage/html using:

make coverage-html

There are three variables to control where the information is collected and where the reports are written:

  • GCOV_BASE_DIR is a cache variable with the full path to a base directory for the coverage information.

    It defaults to ${CMAKE_BUILD_DIR}/coverage.

  • GCOV_INFO_FILE is a cache varible with the full path to the info file for the collected coverage information.

    It defaults to ${GCOV_BASE_DIR}/coverage.info.

  • GCOV_XML_FILE is a cache varible with the full path to the XML file for the collected coverage information.

    It defaults to ${GCOV_BASE_DIR}/coverage.xml.

  • GCOV_HTML_DIR is a cache variable with the full path to the directory where the HTML coverage report will be generated.

    It defaults to ${GCOV_BASE_DIR}/html.
