get_display_recipient's annotation clashes with other wrong annotations.
Fix those wrong annotations.
Since get_display_recipient returns a Union, use isinstance checks and
casts to make mypy checks succeed.
We'll likely want to follow this up with:
(1) Making Let's Encrypt the default instructions for getting a cert.
(2) Moving the "how to get an SSL cert" discussion to its own page.
(3) Eliminating the duplicate content in zulip.org/server.html
But this is definitely an improvement!
Identify functions which return QuerySets and give them a return type
`Sequence` with appropriate parameter. Typing them as QuerySet will
not be useful since generic stubs for QuerySets are not available and
not knowing the type of QuerySets is hardly useful for type checking.
generate_random_token used to return a value of type six.binary_type
and its return type was annotated as `str`. This commit fixes that
by making it return a value of type `six.text_type` and updating
the annotation accordingly.
Also fix clashing annnotations.
Change choices of UserProfile.avatar_sources and UserProfile.tutorial_status
from str literals to unicode literals. This is done because these fields
are CharFields, which are of type `six.text_type`. So the set of values
which they can take should also be of the type `six.text_type`.
Also fix clashing annotations.
Change `str` to `text_type` in annotations in zerver/models.py
related to realm emoji and realm filters.
Also fix clashing annotations in zerver/lib/bugdown/__init__.py.
Due to a cyclic dependency issue, functions having models as parameters
were annotated as Any.
That issue is fixed by importing models inside an `if False:` block,
so that mypy sees them but they are not imported at runtime.
In update_user_profile_caches, the return type in annotation was
marked as Any. Change that to None because, nothing is being returned
in that function.
This changes the type annotations for the cache keys in Zulip to be
consistently text_type, and updates the annotations for values that
are used as cache keys across the codebase.
str_utils.py has functions for converting strings from one type to
another. It also has a TypeVar called NonBinaryStr, which is like AnyStr
except that it doesn't allow bytes.
The previous Markdown syntax didn't work correctly on ReadTheDocs, and
now that we have Coveralls reporting backend test coverage as well,
describing our coverage as just "mypy static type" is no longer accurate.
Fixes#964.
Now that we have a working S3 mock and an effective way to toggle the
upload backend that Zulip is using, we can re-enable this important
end-to-end test of the Zulip S3 upload backend.
