MDEV-29251 Set output directories during compilation
..to create s directory layout that closely resembles zip/tarball/MSI
install.
If we call ${CMAKE_BINARY_DIR} rsp CMAKE_BINARY_DIR/$<CONFIG>
$build_dir , then the compilation will place executables into
$build_dir/bin, and plugins into $build_dir/lib/plugins
Immediate benefits are
- searching, copying or symlinking of plugins in mtr is no more necessary
- searching for executables in mtr is simplified.
- Windows mariadbd.exe will to automatically set correct default
plugin directory (it had always been relative to location of the exe itself)
Other changes
"initial_database" target will create datadir $buildroot/data
directory, instead of $buildroot/sql/data, to still allow
server on Windows to start by just typing <path-to-mysqld> --console in
the shell.
MDEV-7567 Add aliases with prefix log_slow for system variables relating to slow query log
post-merge fixes:
* remove log_slow_queries_not_using_indexes, no need to create variables
that are deprecated since the moment of creation
* rename log_slow_query_enable->log_slow_query
no other variable uses *_enable pattern
* MDEV-29626 Assertion `self == &Sys_slow_query_log' failed in fix_log_state
* tests
MDEV-7567 Add aliases with prefix log_slow for system variables relating to slow query log.
Thus, all these variables will be
grouped together and more logically named.
Descriptions for the old variables were updated to indicate they are
now aliases for the newly introduced variables with prefix log_slow.
log_slow_queries_not_using_indexes_filter will not be addressed
in this merge request.
log_throttle_queries_not_using_indexes seems to no longer be in use.
MTR tests are also updated to include the new variable names.
