The timestamp used for new login notifications always used the 12-hour
format. Instead of that, we use now the one preferred by the user, as
reflected in their settings.
Issue: When you created a new organization with /new, the "new login"
emails were emailed. We previously had a hack of adding the
.just_registered property to the user Python object to attempt to
prevent the emails, and checking that in zerver/signals.py. This
commit gets rid of the .just_registered check.
Instead of the .just_registered check, this checks if the user has
joined more than a minute before.
A test test_dont_send_login_emails_for_new_user_registration_logins
already exists.
Tweaked by tabbott to introduce the constant JUST_CREATED_THRESHOLD.
Fixes#10179.
Email notifications for new logins displayed the login timestamp's
timezone in the location format (e.g. "Asia/Taipei"). Since that can
lead users to understand the login came from that place, the timezone in
those emails is now represented in +/-HHMM format.
Fixes#10178.
This commit prepares us to introduce a StreamLite class. For
these tests, we don't care about the actual contents of the
Stream, just the right stream is there.
Previously, we were checking for "Zulip" entries in User-Agent strings
at the very end of the list, not the beginning. A Zulip User-Agent
should have priority, since it includes the User-Agent strings for a
lot of other browsers, and also it will always be the most specific
value.
