mx doesn't support http_proxys requiring authorization (aka following the format http:https://user:password@host:port)

[zakkak]

mx appears to only support unauthorized http_proxys following the format http:https://host:port while it should also support http:https://user:password@host:port and set http.proxyUser and http.proxyPassword accordingly.

The code at fault is:

mx/mx.py

Lines 12966 to 12981 in 29c0deb

	def _parse_http_proxy(envVarNames):
	"""
	Parses the value of the first existing environment variable named
	in `envVarNames` into a host and port tuple where port is None if
	it's not present in the environment variable.
	"""
	p = re.compile(r'(?:https?:https://)?([^:]+):?(\d+)?/?$')
	for name in envVarNames:
	value = get_env(name)
	if value:
	m = p.match(value)
	if m:
	return m.group(1), m.group(2)
	else:
	abort("Value of " + name + " is not valid: " + value)
	return (None, None)
