One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

	# generate super secret private key
	# (not really, this key and the certificate are "throwaway" items)
	openssl genrsa -des3 -out ssl.key 1024

	# generate the self-signed certificate
	openssl req -new -x509 -nodes -sha1 -days 365 -key ssl.key -out ssl.crt

	# create decrypted version of key so that nginx can be started without a passphrase
	openssl rsa -in ssl.key -out ssl.key.insecure
	chmod 600 ssl.key.insecure

	def acquire(name):
	tries = 0
	while True:
	tries += 1
	if tries >= 30:
	raise Exception("Couldn't acquire lock on mutex "+name)
	try:
	n = r.incr("lock-"+name)
	if n == 1:
	return True
