This change affects realm_users and realm_non_active_users.
Note that we still send full avatar urls in realm_user/add
events, so apply_events has to do something mildly hacky to
turn the avatar_url to None in that case.
Fixing the event is probably not worth the trouble, as single
urls are not bandwidth hogs; we only need this optimization
for bulk data.
This change affects these values:
* page_params.avatar_url
* page_params.avatar_url_medium
It requires passing the client_gravatar flag through this
codepath:
* home_real
* do_events_register
* fetch_initial_state_data
* avatar_url
Seems like the more logical check. Also, the previous code makes it feel
like there is a potential vulnerability where one could get an email change
object in a realm where email changes are disabled, and then open that link
while logged in to a different realm.
While we're at it, remove the unnecessary check that the user is
logged in when clicking the confirmation link; that creates
unnecessary trouble for users who use multiple browsers.
Removes an assert, which at this point is there just for readability, since
the second argument to
get_object_from_key(confirmation_key, Confirmation.EMAIL_CHANGE)
ensures that the returned object is of the correct type.
This commit allows clients to register client_gravatar=True, and
then we recognize that flag for message events. If the flag is
True, we will not calculate gravatar URLs and let the clients do
it themselves. (Clients can calculate gravatar URLs based on
emails with just a little bit of code.)
This refactoring doesn't change behavior, but it sets us up
to more easily handle a register setting for `client_gravatar`,
which will allow clients to tell us they're going to compute
their own gravatar URLs.
The `client_gravatar` flag already exists in our code, but it
is only used for Django views (users/messages) but not for
Zulip events.
The main change is to move the call to `set_sender_avatar` into
`finalize_payload`, which adds the boolean `client_gravatar`
parameter to that function. And then we update various callers
to supply that flag.
One small performance benefit of this change is that we now
lazily compute the client message payloads in
`event_queue.process_message_event` now, so this will improve
performance if all interested clients have the same value of
`apply_markdown`. But the change here is really preparing us
for the additional boolean parameter, which will cause us to
have four variations of the payload.
