Keeps asking me for SVN username/password for each module upgrade

Hello guys,

This problem literally caused havoc at my end. When I did

drush up --svnsync --svncommit --svnmessage="updating..."

It got a to prompt which asked me for password for "www-data", of course this is the user I'm logged in as. So I pressed enter, got to an empty line which I later found out was prompting me for username, typed my username, was asked for a password, typed the password, and the module was upgraded.

This repeated around 25 times or so for each one of the module upgrades!!! At the end and after I got sore hands, it crashed with an error "mysql server has gone away". Which makes sense if the mysql connection was opened at the beginning of the drush script rather after the module upgrades. Anyway, sql database updates failed, not everything was committed, drush didn't completely finish its work, I was left with a very big mess.

Question is, why and how do I prevent the script from continuously asking me for my svn auth? Another question on the side is that I noticed drush was trying to add the files folder and settings.php file, I added them to the global config global-ignores, should that be enough to prevent drush from trying to add them? Or does drush not abide by /etc/subversion/config file?

Thanks!
