Description
SET PERSIST innodb_buffer_pool_size= 1024;
and restarting the server causes `innodb_buffer_pool_size` to be uninitialized.
Valgrind shows:
==28138== by 0x405946D: innodb_buffer_pool_size_update(THD*, SYS_VAR*, void*, void const*) (ha_innodb.cc:18643) ==28138== by 0x2C1DE1E: sys_var_pluginvar::global_update(THD*, set_var*) (sql_plugin_var.cc:417) ==28138== by 0x2AC97D6: sys_var::update(THD*, set_var*) (set_var.cc:252) ==28138== by 0x2ACBEDE: set_var::update(THD*) (set_var.cc:1006) ==28138== by 0x2ACB2FE: sql_set_variables(THD*, List<set_var_base>*, bool) (set_var.cc:771) ==28138== by 0x2A8D33C: Persisted_variables_cache::set_persist_options(bool) (persisted_variable.cc:723) ==28138== by 0x2A031EF: mysqld_main(int, char**) (mysqld.cc:6616) ==28138== by 0x2823BE4: main (main.cc:30)
I located the issue to `set_var.save_result` that is not set in `innodb_buffer_pool_size_validate(save)`.
