----------------------------------------
Summary: Configuration related to reverse proxy is loaded using
wrong data type.
Key: AIRFLOW-6549
URL: https://issues.apache.org/jira/browse/AIRFLOW-6549
Project: Apache Airflow
Issue Type: Bug
Components: configuration
Affects Versions: 1.10.7
Reporter: Mathieu Poussin
The configuration management system is loading the variables related to reverse
proxy fix handling with the wrong format, example with the following
configuration :
{code:java}
enable_proxy_fix = True
proxy_fix_x_for = 1
proxy_fix_x_proto = 1
proxy_fix_x_host = 1
proxy_fix_x_port = 1
proxy_fix_x_prefix = 1
{code}
When running the webserver, a 500 is returned with the following stacktrace:
{code:java}
TypeError: '>=' not supported between instances of 'int' and 'str'
File "flask/app.py", line 2463, in __call__
return self.wsgi_app(environ, start_response)
File "werkzeug/middleware/proxy_fix.py", line 195, in __call__
x_for = self._get_trusted_comma(self.x_for,
environ_get("HTTP_X_FORWARDED_FOR"))
File "werkzeug/middleware/proxy_fix.py", line 166, in _get_trusted_comma
if len(values) >= trusted:
{code}
When analysic local variable (thanks Sentry), I can see that trusted is equal
to '1' (as string) and not 1 (as int) as it should be.
This makes the usage of reverse proxy impossible.
