Emojis which are represented by a sequence of codepoints or emojis
with ZWJ are not included until we implement a mechanism for dealing
with their unicode versions.
Fixes: #6279.
Instead of using `unified_reactions` mapping start using
`name_to_codepoint` mapping for converting emoji name to
codepoints. We were using `unified_reactions` mapping
because prior to emoji web PR `name_to_codepoint` mapping
was generated using emoji_map.json which contained old
codepoints but for reactions new codepoints were required
to display them using sprite sheets.
Create a new custom email backend which would automatically
logs the emails that are send in the dev environment as
well as print a friendly message in console to visit /emails
for accessing all the emails that are sent in dev environment.
Since django.core.mail.backends.console.EmailBackend is no longer
userd emails would not be printed to the console anymore.
We now do push notifications and missed message emails
for offline users who are subscribed to the stream for
a message that has been edited, but we short circuit
the offline-notification logic for any user who presumably
would have already received a notification on the original
message.
This effectively boils down to sending notifications to newly
mentioned users. The motivating use case here is that you
forget to mention somebody in a message, and then you edit
the message to mention the person. If they are offline, they
will now get pushed notifications and missed message emails,
with some minor caveats.
We try to mostly use the same techniques here as the
send-message code path, and we share common code with the
send-message path once we get to the Tornado layer and call
maybe_enqueue_notifications.
The major places where we differ are in a function called
maybe_enqueue_notifications_for_message_update, and the top
of that function short circuits a bunch of cases where we
can mostly assume that the original message had an offline
notification.
We can expect a couple changes in the future:
* Requirements may change here, and it might make sense
to send offline notifications on the update side even
in circumstances where the original message had a
notification.
* We may track more notifications in a DB model, which
may simplify our short-circuit logic.
In the view/action layer, we already had two separate codepaths
for send-message and update-message, but this mostly echoes
what the send-message path does in terms of collecting data
about recipients.
They're rarely useful, usually displayed invisibly in most tools
anyway, and this helps make sure the message makes it into Zulip
rather than being rejected.
Postgres doesn't like them, we don't have an obvious way to escape
them, and they tend to be sent by buggy tools where it'd be better for
the user to get an error.
This fixes a 500 we were getting occasionally.
We have two different concepts of "idle", and this function
is based on the "presence" aspect of idleness. There is also
idleness in terms of a user having no current client
descriptors accepting messages, and we check that later in
the process for things like sending missed message emails.
This commit migrates all webhooks to use check_send_stream_message
instead of check_send_message. The only two webhooks that still
use check_send_message are our yo and teamcity webhooks. They
both use check_send_message for private messages.
check_send_stream_message is a simpler version of
check_send_message for sending messages where the addressee is
a stream. Instead of relying on Addressee.legacy_build,
check_send_stream_message uses Addressee.for_stream. Consequently,
it eschews many of check_send_message's kwargs that aren't needed
when the intended recipient of a message is a stream.
