Description Karel Volný 2013-12-10 13:00:29 UTC 
cloning to track failure in our test for the appropriate RHEL version

+++ This bug was initially created as a clone of Bug #1039975 +++

Description of problem:
Trying to run mysql_config without parameters, it returns nonzero exit code. But this is not an error, the application should return zero.

Version-Release number of selected component (if applicable):
mariadb-5.5.33a-1.fc19

How reproducible:
always

Steps to Reproduce:
1. mysql_config >/dev/null; echo $?

Actual results:
1

Expected results:
0

Additional info:
from the manpage:

"If you invoke mysql_config with no options, it displays a list of all options that it supports, and their values:"

so, invoking without parameters is correct usage ...

note also that it'd be nice to support the "--help" option, but that's more RFE material than a bug
Comment 2 Karel Volný 2014-12-02 10:44:29 UTC 
just FTR, there are more binaries with similar problem:

`mysql_waitpid --help` returns 255 despite "--help" is valid option

`mysqladmin --help` returns 1 despite "--help" is valid option

`myisam_ftdump --help` returns 1 despite "--help" is valid option

`resolve_stack_dump --help` returns 1 despite "--help" is valid option

(should I file it as a new bug?)
