Previously, if a user subscribed to a stream with
history_public_to_subscribers, and then was looking at old messages in
the stream, they would not get live-updates for that stream, because
of the structure in how notify_reaction_update only looked at
UserMessage rows (we had a previous workaround involving the
`historical` field in `UserMessage` which had already made it work if
the user themselves added the reaction).
We fix this by including all subscribers with history access in the
set of recipients for update events.
Fixes a bug that was confused with #16942.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated. This is unlikely
to come up in common usage, but may be confusing when testing.
Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID. `!`s. Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.
Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.
Fixes#17016.
Instead of validating `op` value later, this commit does that
in `REQ`.
Also helps avoiding duplication of this validation when
stream typing notifications feature is added.
With the previous two commits deployed, we're ready to use the
denormalization to optimize the query.
With dev environment db prepared using
./manage.py populate_db --extra-users=2000 --extra-streams=400
this takes the execution time of the query in
bulk_get_subscriber_user_ids from 1.5-1.6s to 0.4-0.5s on my machine.
The new comment explains the issue in some detail, but basically if we
deactivate the bots first, then an error partway through is corrected
by a retry; if we deactivate the user first, then we may leak
undeactivated bots if a failure occurs.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.
These procedures should be done atomically overall, with the exception
of the code that sends events to avoid block if there's a delay
communicating with Tornado.
We add the savepoint=False on underlying function that already
executes inside an atomic context - to avoid the overhead of creating
savepoints where they aren't needed.
* `op` (operation) field, added in f6fb88549f, was never intended for
`custom_profile_fields` event. This commit removes the `op` as it doesn't
have any use in the code.
* As a part of cleanup, this also eliminates the schema check warnings
for `custom_profile_fields` event, mentioned in #17568.
Emails are not unique, so we can only sensibly cache using keys formed
with both email and realm.
This requires adding a new cache key function for caching by delivery
email - user_profile_delivery_email_cache_key.
This add the schema checker, openapi schema, and also a test for
realm/deactivated event.
With several block comments by tabbott explaining the logic behind our
behavior here.
Part of #17568.
This is a prep commit which modifies the
`send_message_moved_breadcrumbs` function to take
message strings as input.
This is done to reuse the function in other places
like the /digress command.
Fixes#17238.
In process_new_human user, the queries were wrong, revoking all invites
sent to the email address, even in other realms than the one where the
new account just got created.
This commmit includes ROLE_MODERATOR in realm_user_count_by_role.
We also update test_change_role in test_audit_log.py to include
changes for moderator role as well.
This is a minor refactor which renames the
notify_topic_moved_streams function to
send_message_moved_breadcrumbs.
This is done because this function will be also used
for other things in the future, when moving streams
or when using the /digress command, for example.
