value of innodb_temp_data_file_path is processed incorrectly with pt-config-diff

[marekb...@gmail.com]

Hi,

I have noticed incorrectly reported difference with pt-config-diff when value ends with number and factor but is not only single numeric value. For example when innodb_temp_data_file_path is set to ibtmp1:12M:autoextend:max:50G pt-config-diff returns:

innodb_temp_data_file_... ibtmp1:12M:autoextend:max:50G 53687091200

Any chance you can share your my.cnf files so we can take a look at how those are set?

Configuration file contains:
innodb_temp_data_file_path = ibtmp1:12M:autoextend:max:50G

Database query returns:
+-------------------------------+
| @@innodb_temp_data_file_path |
+-------------------------------+

| ibtmp1:12M:autoextend:max:50G |

+-------------------------------+

The value is converted in subroutine _process_val where only last
numeric value and factor is matched with regex and any preceding
string is stripped out:

if ( my ($num, $factor) = $val =~ m/(\d+)([KMGT])b?$/i ) {
