There was an issue that occurred with this order of operations:
* An IMAP topic was created by emailing a group
* A second user was invited to the topic (not the OP and not the group)
* A user with access to the group replies to the topic
* The second user receives a user_private_message notification email because of their involvement in the topic
* The second user replies to the email via email
This new reply would then go and notify the other group PM users, except for those who emailed the group topic directly, which is handled via the group SMTP mailer. However because the new post already has an incoming email because it is parsed via the Email::Receiver via POP3 the group SMTP section of the post alerter is skipped, and the group's email address is not ignored for the user_private_message notification.
This PR fixes it so the group is not ever sent an email via the PM notification. This is important because any new emails in the group's IMAP inbox will be picked up by the Imap::Sync code and created as a new topic which is not at all desirable.
Also in this PR I split up the specs a bit more for group SMTP in the post alerter to make them easier to read and they each only test one thing.
Fixes bug introduced by bd25627198
What happens is we send notifications to everyone involved in the group inbox topic about new posts, however we pass the param `skip_send_email_to: email_addresses`. In the above commit I removed the group email address from this `email_addresses` array. This breaks the IMAP inbox because we email the group with the reply, and the IMAP sync tool finds this email and opens a new unrelated topic with it.
This PR fixes a race condition with the IMAP notification code. In the `Email::Receiver` we call the `NewPostManager` to create the post and enqueue jobs and sends alerts via `PostAlerter`. However, if the post alerter reaches the `notify_pm_users` and the `group_notifying_via_smtp` method _before_ the incoming email is updated with the post and topic, we unnecessarily send a notification to the person who just posted. The result of this is that the IMAP syncer re-imports the email sent to the user about their own post, which looks like this in the group inbox:
To fix this, we skip the jobs enqueued by `NewPostManager` and only enqueue them with `PostJobsEnqueuer` manually _after_ the incoming email record has been updated with the post and topic.
Other improvements:
* Moved code to calculate email addresses from `IncomingEmail` records into the topic, with a group passed in, for easier testing and debugging. It is not the responsibility of the post alerter to figure this stuff out.
* Add shortcut methods on `IncomingEmail` to split or provide an empty array for to and cc addresses to avoid repetition.
* FEATURE: don't notify about changed tags for a private message
Only staff members observing specific tag should receive a notification
* FIX: remove other category which is not used
* FIX: improved specs to ensure that revise was succesful
This ensures that at a minimum you are notified once a day of
repeat edits by the same user.
Long term we may consider winding this down to say 1 hour or
making it configurable.
Due to a refactor in e90f9e5cc4 we stopped notifying on edits if
a user liked a post and then edited.
The like could have happened a long time ago so this gets extra
confusing.
This change makes the suppression more deliberate. We only want
to suppress quite/link/mention if the user already got a reply
notification.
We can expand this suppression if it is not enough.
* FIX: when unread reply notification exists don't create new
From time to time, the user is creating a reply post and then they want to add additional details. They edit an existing post and for example, add a quote from a previous one.
In that situation, if the user to whom reply was directed to already have the unread notification, we should not create the new one.
That behaviour was mentioned here: https://meta.discourse.org/t/reply-then-edit-to-add-quote-notification-redundancy/138358
* FIX: dont create new notification if already exists
Previously, `notify_first_post_users` was loading all users into memory simultaneously, which can cause Sidekiq to run out of memory for large sites. `notify_post_users` was loading every user one-by-one in a loop.
This commit makes both these functions load users in batches of 100. This should make the memory usage of `notify_first_post_users` lower, and reduce the number of queries required in `notify_post_users`.
Regression was created here:
https://github.com/discourse/discourse/pull/8750
When tag or category is added and the user is watching that category/tag
we changed notification type to `edited` instead of `new post`.
However, the logic here should be a little bit more sophisticated.
If the user has already seen the post, notification should be `edited`.
However, when user hasn't yet seen post, notification should be "new
reply". The case for that is when for example topic is under private
category and set for publishing later. In that case, we modify an
existing topic, however, for a user, it is like a new post.
Discussion on meta:
https://meta.discourse.org/t/publication-of-timed-topics-dont-trigger-new-topic-notifications/139335/13
There is a feature, that when tag or category is added to the topic,
customers who are watching that category or tag are notified.
The problem is that it is using default notification type "new post"
It would be better to use "new post" only when there really is a new
post and "edited" when categories or tags were modified.
I made a regression here 17366d3bcc (diff-ddeebb36d131f89ca91be9d04c2baefaR10)
When the tag is added, people watching specific tag are notified but also people watching specific category.
Therefore, `notify_post_users` should accept options who should be notified.
So when `category` is added to the topic, users watching topic and users watching category are notified.
When `tag` is added to the topic, users watching topic and users watching tag are notified
Finally, when a new post is created, everybody is notified, topic watchers, category watchers, tag watchers.
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

Previously the push notification code path was not tested for notification
collapsing. This happens if you get multiple replies to a topic you are
watching.
Previously we would notify on small actions if they were whispers
this inconsistently lead to all sorts of problems including
- collapsed "N replies" after assign
- empty push notifications
New behavior adds an api to explicitly send push notifications as well
if needed: create_notification_alert
* Add revision number to notification url
* Pop modal on route change
* Add semicolon
* Ensure modal pops even when navigating within a topic
* Ensure modal pops when visiting from other page
* Fix eslint errors
* Fix prettier errors
* Add callback for notification item click
* Remove stray revisionUrl function
* Rename to afterRouteComplete
Introduce new patterns for direct sql that are safe and fast.
MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API
- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder
