When we create a stream, we usually send a welcome message on the
stream itself as well as an announcement on the announcement stream,
but we no longer PM the individual users. Hopefully this will be
more pleasant for users (less spammy), and it also will make creating a
stream a lot faster.
We still send notifications when we add subscribers to an existing
stream.
We now pre-populate the streams in DEFAULT_NEW_REALM_STREAMS
(social/general/zulip, unless somebody changes settings.py) with
welcome messages. This makes the streams appear to be active
right away, and it also gives the Zulip realm less of a
blank-slate feeling when you create it.
This change only affects the normal web-based create-realm flow.
It doesn't impact the management commands for creating realms
or setting default streams.
This makes the new user experience in an active community like
chat.zulip.org substantially nicer, since the new user will have the
same level of initial messages to populate topics (etc.) as an
existing user who is caught up.
Without this, there was an undue level of fading-for-inactivity in the
default streams.
This fixes 2 issues:
* The term "@-mentioned" is simplified to "mentioned".
* We would incorrectly list other people who sent context messages as
among the people who mentioned you.
Now, in the event of messages between two other members of a huddle,
the missed message emails are threaded in "Group PMs with name1 and
name2" and not in separate threads by sender.
Also, now the order of recipients in get_display_recipient consistent
with the order of names that appears in the list of personal messages
on the left sidebar.
Fixes most of #4553.
Since realm emoji are now required to be lowercase,
an appropriate migration was added to retroactively
fix any emoji that might have contained uppercase
letters.
Also, the validator on the model was changed to
reject uppercase letters.
These handlers will kick into action when is_signup is False. In case
the account exists, the user will be logged in, otherwise, user will
be asked if they want to proceed to registration.
This fixes a major performance issue, where we would fetch
user_profile objects inside a code path that had already bulk-fetched
the necessary user objects.
Like the similar related changes we just made, the fix is to marshall
and pass the data into the avatar library directly.
Due to the refactoring of the avatar URL codepath that added realm IDs
to the URLs, we ended up calling `get_user_profile_by_email` inside
`get_avatar_url`, which in turns was called in a loop over all users
in a realm.
Needless to say, this resulted in a significant performance problem.
We fix this issue by passing in the data needed to compute the avatar
URL, rather than looking it up by email address.
