Aditya Bansal 6ad22f4092 pep8: Add compliance with rule E261 to streams.py. 2017-05-07 23:21:50 -07:00
Akash Kothawale 4c2bfae83e get_stream: Throw DoesNotExist if stream is not found. 
This makes get_stream match get_realm, get_user_profile_by_email,
etc., in interface, and is more convenient for mypy annotations
because `get_stream` now doesn't return an Optional[Stream].

Tim Abbott 0af34ee710 streams: Add zerver/lib/streams.py library for security checks. 
The goal of this library is to make it a lot easier to prevent bugs
like CVE-2017-0881 by having all of our views logic for fetching a
stream go through a couple carefully tested code paths.
