Rather than pass around a list of message objects in-memory, we
instead keep the same constructed QuerySet which includes the later
propagated messages (if any), and use that same query to pick out
affected Attachment objects, rather than limiting to the set of ids.
This is not necessarily a win -- the list of message-ids *may* be very
long, and thus the query may be more concise, easier to send to
PostgreSQL, and faster for PostgreSQL to parse. However, the list of
ids is almost certainly better-indexed.
After processing the move, the QuerySet must be re-defined as a search
of ids (and possibly a very long list of such), since there is no
other way which is guaranteed to correctly single out the moved
messages. At this point, it is mostly equivalent to the list of
Message objects, and certainly takes no less memory.
Rather than use `bulk_update()` to batch-move chunks of messages, use
a single SQL query to move the messages. This is much more efficient
for large topic moves. Since the `edit_history` field is not yet
JSON (see #26496) this requires that PostgreSQL cast the current data
into `jsonb`, append the new data (also cast to `jsonb`), and then
re-cast that as text.
For single-message moves, this _increases_ the SQL query count by one,
since we have to re-query for the updated data from the database after
the bulk update. However, this is overall still a performance
improvement, which improves to 2x or 3x for larger topic moves. Below
is a table of duration in seconds to run `do_update_message` to move a
topic to a new stream, based on messages in the topic, for before and
after this change:
| Topic size | Before | After |
| ---------- | -------- | ------- |
| 1 | 0.1036 | 0.0868 |
| 2 | 0.1108 | 0.0925 |
| 5 | 0.1139 | 0.0959 |
| 10 | 0.1218 | 0.0972 |
| 20 | 0.1310 | 0.1098 |
| 50 | 0.1759 | 0.1366 |
| 100 | 0.2307 | 0.1662 |
| 200 | 0.3880 | 0.2229 |
| 500 | 0.7676 | 0.4052 |
| 1000 | 1.3990 | 0.6848 |
| 2000 | 2.9706 | 1.3370 |
| 5000 | 7.5218 | 3.2882 |
| 10000 | 14.0272 | 5.4434 |
This applies access restrictions in SQL, so that individual messages
do not need to be walked one-by-one. It only functions for stream
messages.
Use of this method significantly speeds up checks if we moved "all
visible messages" in a topic, since we no longer need to walk every
remaining message in the old topic to determine that at least one was
visible to the user. Similarly, it significantly speeds up merging
into existing topics, since it no longer must walk every message in
the new topic to determine if the user could see at least one.
Finally, it unlocks the ability to bulk-update only messages the user
has access to, in a single query (see subsequent commit).
Instead of charging the customer using the attached payment
method and then creating the invoice, we create an invoice and
force an immediate payment for the invoice via the attached
payment method.
This is a preparatory commit. It adds an extra notification_event_type
to the Recipient type. This can be used to differentiate between
typing notifications and message edit typing notifications since
they send different events.
This is a preparatory commit that refactors the check_update_message
method to extract the checks containing whether a user can edit the
message or not into a separate method -validate_message_content_edit,
so that it can be re used later.
This commit extracts the edited notice computation logic of
edited_in_left_col, edited_alongside_sender and edited_status_message
to a new function - set_edited_notice_locations and calls it right
after the method merge_message_groups.
This is a preparatory commit, and is done since theses three variables
were previously wrongly initialized in the beginning for live messages
received.
We also introduce a modified flag to decide whether to display the
edited notice or not. This is useful since now we are computing
the edited notice values even when messages are not edited, and
hence we show the notices only when the modified flag is true.
The function body contains only two conditionals, so the
'switch' statements can be replaced with simple 'if's that
return immediately, thus making the code block cleaner.
Earlier, we were not setting `free_trial` = False for legacy
customers in `do_upgrade`.
This lead to a bug where customers were upgraded even before the
payment was complete. 'process_initial_upgrade' was always getting
called instead of 'setup_upgrade_payment_intent_and_charge'.
This commit fixes the incorrect behaviour.
This logic was part of the original desktop notifications
implementation in 4cb0c6225e.
There's no apparent standard for the number of characters allowed to
be shown in a desktop notification, so truncating at 150 characters
arbitrarily seems wrong.
Further, we've decided it's no longer a priority to truncate at word
boundaries, we can rely on the browser to take responsibility for
truncation.
Fixes#25260.
- Updates incoming webhooks overview and walkthrough to be consistent
