Last active June 7, 2016 12:46
This script creates test users that are the same as created by eucalyptus ui tests. So, if you're setting up a test cloud by some other means (like kickstarting a package-built cloud), you can run this after getting the admin credentials.
echo "{ \"Statement\": [ { \"Effect\": \"Allow\", \"Action\": \"*\", \"Resource\": \"*\" } ] }" >all.policy

ADMIN=`cat .euca/euca-admin.ini |grep "^user" |awk '{ print $3; }'`

dkavanagh / switchbranch.sh
Created February 5, 2013 20:48
This script is called by passing in a new branch name. It is used by eucalyptus where we have sub-modules that require updating as well as the top level refs. Errors will cause things to stop (like changes not checked in).
git submodule foreach git checkout $1
git submodule foreach git pull origin $1
git checkout $1
git pull origin $1

pushtoremote.sh - I revised this to work with the current branch because I never ended up passing in anything other than that.

dkavanagh / http redirect example
Last active December 18, 2015 09:18
http redirector that works with tornado. start_redirector (in my code) gets called in a background thread.. ignore the callback arg, which is None, but kwargs is passed in containing use_ssl and port as values for the redirect handler.
def start_redirector(kwargs, callback):
# can't use tornado for this (not threadsafe). Must use something else, something simpler!
http_port = 8888
if eucaconsole.config.has_option('server', 'http.port'):
http_port = eucaconsole.config.getint('server', 'http.port')
server = BaseHTTPServer.HTTPServer(('localhost', http_port),
lambda *args: RedirectHandler(kwargs, *args))
server.serve_forever()
class RedirectHandler(BaseHTTPRequestHandler):
