Issue:
------
New test case mysql_embedded.test was failing on pb2.
Description:
------------
To run this test case executable libmysqld/examples/mysql_embedded is required.
But as per /libmysqld/examples/cmake_install.cmake this executable doesn't get
copied to <install_dir> when mysql is installed at <install_dir>.That is the
reason it was passing in my local branch and failed on pb2 when pushed.
Solution;
---------
Added code in mysql-test-run.pl, which will try to see if this file exists.If
It doesn't exist, test case will be skipped with a skip message. New code in
mysql-test-run.pl looks only for directory libmysqld/examples/mysql_embedded
because this is the only place where this file could/does exist.
mysql-test/mysql-test-run.pl:
Added new variable for mysql_embedded executable.
mysql-test/t/disabled.def:
enabled mysql_embedded.test which was disabled earlier.
mysql-test/t/mysql_embedded.test:
Modified test case to first verify if mysql_embedded executable exists. If
it does not, skip the test.
Issue:
When libmysqld/example/mysql_embedded is executed, it was getting abort. Its a
regression as it was working in 5.1 and failed in 5.5. Issue is there because
remaining_argc/remaining_argv were not getting assigned correctly in
init_embedded_server() which were being used later in init_common_variable().
Solution:
Rectified code to pass correct argc/argv to be used in init_common_variable().
libmysqld/lib_sql.cc:
Rectified remaining_argc/remaining_argv assignment.
mysql-test/r/mysql_embedded.result:
Result file for the test case added.
mysql-test/t/mysql_embedded.test:
Added test case to verify libmysqld/example/mysql_embedded works.
