When we push a device token, we want to clean out any other user's
tokens on the device, but not the current user's. We were wiping
away our own token, if it existed, before creating it again. This
was probably never a user-facing problem; it just made for dead code
and a little unnecessary DB churn. By excluding the current user
from the delete() call, we exercise the update path in our tests now,
so we have 100% coverage.
We now have 100% coverage on views/push_notifications.py, modulo
some dead code which will be addressed in the next commit.
There were some existing tests in text_external.py, but that
module is really intended for tests that hit external services.
The view is a really simple API that updates a DB table, and the
new test code focuses on error handling and idempotency as well
as the happy path.
Apparently, in urllib.parse, one need to extract the query string from
the rest of the URL before parsing the query string, otherwise the
very first query parameter will have rest of the URL in its name.
This results in a nondeterministic failure that happens 1/N of the
time, where N is the number of fields marshalled from a dictionary
into the query string.
This commit extracts compose_views() from update_subscriptions_backend(),
and it implements the correct behavior for forcing transactions to roll
back, which is to raise an exception.
There were really three steps in this commit:
- Extract buggy code to compose_views().
- Add tests on compose_views().
- Fix bugs exposed by the new tests by converting errors to exceptions.
In HTML, the line break immediately following a start tag is ignored
(see: https://www.w3.org/TR/html4/appendix/notes.html#h-B.3.1). An
extra span tag has been introduced in the upstream Pygments
HtmlFormatter in order to preserve the first new line. The Bugdown
Tests as well as our fenced_code.js frontend markdown processor have
been updated to reflect this new behavior.
We're now at the point where 100% of functions checked by mypy is
fully annotated; to avoid regressions, we're enforcing the requirement
that it stay this way. We still have a moderate amount of code that
is neither checked by mypy nor annotated, but it seems reasonable to
annotate that code at the same time as we get a chance to fix the mypy
issues in it.
This is implemented by using the --disallow-untyped-defs option in
mypy by default.
