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].	2017-03-23 15:42:00 -07:00

Tim Abbott	02f5ef1d23	streams: Move filter_stream_authorization to lib.	2017-01-29 20:26:59 -08:00
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.	2017-01-29 20:26:58 -08:00
