Description:
While experimenting with a CodeSonar plugin we develop, we noticed a potential bug in file "sql/rpl_info_factory.cc" line 536 function Rpl_info_factory::init_repository_metadata:

my_stpcpy(mi_file_data.name, master_info_file);
my_stpcpy(mi_file_data.pattern, master_info_file);
rli_file_data.name_indexed= false; //HERE

Shouldn't you set the field of "mi_file_data" instead of the field of "rli_file_data"?

Thanks,
Petru Florin Mihancea

Hi,

Thank you for your bug report.

You are writing about source code files and bug numbers, while you do not state which version and which release are you writing about.

If this is a new code in the patch that is not released yet, then we can not verify it until it is released.

Ups, sorry! It is version 5.7.
