[oe-commits] [openembedded-core] 09/23: oe-git-proxy: support username / password in http proxy

[git at git.openembedded.org]

rpurdie pushed a commit to branch master
in repository openembedded-core.

commit ce4ff3dd80379e1bf71a967e0512591aaa046308
Author: André Draszik <adraszik at tycoint.com>
AuthorDate: Wed Mar 23 10:47:05 2016 +0100

    oe-git-proxy: support username / password in http proxy
    
    We also make sure to correctly support usernames that contain spaces.
    
    For simplicity sed + regex has been replaced with shell parameter expansion,
    which works in both, bash and dash.
