The older fixture for this event assumed that the "assignee" key
had a value of '{}' if no one was assigned to a PR anymore.
However, that is no longer true because testing with requestbin
showed that in the latest JSON payload for this event, the key
"assignee" now has the value of 'null' (None when converted to
Python) when a user is unassigned from a PR. The current code
didn't handle this correctly. This commit makes sure it does!
Its unclear as to whether the old fixture was simply wrong or
whether GitHub changed its payloads in any way.
Changes made to get_push_commits_event_message in
zerver/lib/webhooks/git.py are common to all Git integrations
that use get_push_commits_event_message. These include github,
github_webhook, gitlab, gogs, bitbucket, bitbucket2. In some
cases (for instance, gitlab), no further changes to gitlab/view.py
will be required to support pushing a local branch without commits;
adding a fixture and tests should suffice.
In cases where the webhook payload doesn't have the username for the
author of a particular commit (this can happen if the author doesn't
have a GitHub account or the author's email is not associated with
their GitHub account), we now use the author's full name to format
messages.
All webhook fixtures in zerver/fixtures/<webhook_name> have now
been moved to dedicated webhook-specific directories under
zerver/webhooks/<webhook_name>/fixtures, where <webhook_name> is
the name of the webhook.
