From 7c12e6c994b3320ef57a13e06f5c445b6bca7935 Mon Sep 17 00:00:00 2001 From: "Bryn M. Reeves" Date: Thu, 22 Jan 2015 15:37:15 +0000 Subject: [PATCH 50/93] [mysql] improve handling of dbuser, dbpass and MYSQL_PWD Make sure that the mysql plugin behaves correctly when given different combinations of values for dbuser, dbpass and MYSQL_PWD. * If dbdump is set then either dbpass or MYSQL_PWD must be set * Warn if dbdump is set and dbuser or dbpass is True/False/null (indicates either 'sosreport -a' or '-k mysql.dbpass') Signed-off-by: Bryn M.
