Description
When using a custom memory allocator, e.g.
[mysqld_safe]
|
malloc-lib=jemalloc
|
When starting MariaDB, the mysqld_safe script attempts to learn which lib directories to use by executing mysql_config command.
However this is only provided by the MariaDB-devel package, and so isn't installed on most production servers.
As such, we get an error each time we start MariaDB, in the form of:
180703 12:52:39 mysqld_safe Can not run mysql_config --variable=pkglibdir from '/usr/bin/mysql_config'
|
MariaDB still starts OK because the mysqld_safe script also looks in the normal lib directories, where jemalloc is installed to by CentOS.
I do not think we need to see this error, as it will be common for mysql_config not to be installed. Perhaps only show the error if the allocator library isn't found in any of the normal library directories?
