We don't actually use the reminder_type for bookmarks anywhere;
we are just storing it. It has no bearing on the UI. It used
to be relevant with the at_desktop bookmark reminders (see
fa572d3a7a)
This commit marks the column as readonly, ignores it, and removes
the index, and it will be dropped in a later PR. Some plugins
are relying on reminder_type partially so some stubs have been
left in place to avoid errors.
We don't need no stinkin' denormalization! This commit ignores
the topic_id column on bookmarks, to be deleted at a later date.
We don't really need this column and it's better to rely on the
post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.
Discourse is sending regularly message to admins when potential problems are persisted. Most of the time they have exactly the same content. In that case, when there are no replies, the old one should be trashed before a new one is created.
This bug was introduced by f66007ec83.
In PostJobsEnqueuer we previously did not fire the after_post_create
event and after_topic_create event for private message topics. This was
changed in the above commit in order to publish message bus messages
for topic tracking state updates. Unfortunately this caused the
NotifyMailingListSubscribers job to be enqueued for all posts including
private messages, and admins and the users involved in the PMs got
emailed the contents of the PMs if they had mailing list mode enabled.
Luckily the impact of this was mitigated by a Guardian#can_see? check
for each mailing list mode user in the NotifyMailingListSubscribers job.
We never want to notify mailing list mode subscribers for private messages
so an early return has been added there, plus the logic in PostJobsEnqueuer
has been fixed, and tests have been added to that class where there were
none before.
This adds a few different things to allow for direct S3 uploads using uppy. **These changes are still not the default.** There are hidden `enable_experimental_image_uploader` and `enable_direct_s3_uploads` settings that must be turned on for any of this code to be used, and even if they are turned on only the User Card Background for the user profile actually uses uppy-image-uploader.
A new `ExternalUploadStub` model and database table is introduced in this pull request. This is used to keep track of uploads that are uploaded to a temporary location in S3 with the direct to S3 code, and they are eventually deleted a) when the direct upload is completed and b) after a certain time period of not being used.
### Starting a direct S3 upload
When an S3 direct upload is initiated with uppy, we first request a presigned PUT URL from the new `generate-presigned-put` endpoint in `UploadsController`. This generates an S3 key in the `temp` folder inside the correct bucket path, along with any metadata from the clientside (e.g. the SHA1 checksum described below). This will also create an `ExternalUploadStub` and store the details of the temp object key and the file being uploaded.
Once the clientside has this URL, uppy will upload the file direct to S3 using the presigned URL. Once the upload is complete we go to the next stage.
### Completing a direct S3 upload
Once the upload to S3 is done we call the new `complete-external-upload` route with the unique identifier of the `ExternalUploadStub` created earlier. Only the user who made the stub can complete the external upload. One of two paths is followed via the `ExternalUploadManager`.
1. If the object in S3 is too large (currently 100mb defined by `ExternalUploadManager::DOWNLOAD_LIMIT`) we do not download and generate the SHA1 for that file. Instead we create the `Upload` record via `UploadCreator` and simply copy it to its final destination on S3 then delete the initial temp file. Several modifications to `UploadCreator` have been made to accommodate this.
2. If the object in S3 is small enough, we download it. When the temporary S3 file is downloaded, we compare the SHA1 checksum generated by the browser with the actual SHA1 checksum of the file generated by ruby. The browser SHA1 checksum is stored on the object in S3 with metadata, and is generated via the `UppyChecksum` plugin. Keep in mind that some browsers will not generate this due to compatibility or other issues.
We then follow the normal `UploadCreator` path with one exception. To cut down on having to re-upload the file again, if there are no changes (such as resizing etc) to the file in `UploadCreator` we follow the same copy + delete temp path that we do for files that are too large.
3. Finally we return the serialized upload record back to the client
There are several errors that could happen that are handled by `UploadsController` as well.
Also in this PR is some refactoring of `displayErrorForUpload` to handle both uppy and jquery file uploader errors.
We now use the group's full name in group SMTP emails, so we are dropping the via #{site_name}. If group owners still want this they can just change the full name of the group.
Currently when bulk-awarding a badge that can be granted multiple times, users in the CSV file are granted the badge once no matter how many times they're listed in the file and only if they don't have the badge already.
This PR adds a new option to the Badge Bulk Award feature so that it's possible to grant users a badge even if they already have the badge and as many times as they appear in the CSV file.
This PR fixes a couple of issues related to group SMTP:
1. When running the group SMTP job, we were exiting early if the email was for the OP because of an IMAP race condition. However this causes issues when replying as a new topic for an existing SMTP topic, as the recipient does not get the OP email which can cause threading problems.
2. When sending emails for a new topic spun out like the issue in 1., we are not maintaining the original subject/topic title because that is based on the incoming email record, which we were not doing because the group SMTP email was never sent because of issue 1.
There was an issue with the TopicTimerEnqueuer where any timer
that failed to enqueue_typed_job with an error would prevent
all other pending timers after the one that errored from running.
To mitigate this we just capture the error and log it (so we can
still fix it if needed for bug crushing) and proceed with the
rest of the timer enqueues.
The commit https://github.com/discourse/discourse/pull/13544 highlighted
this issue originally in hosted sites.

Skip group SMTP email (and add log) if:

We do not want to show the In Reply To section of the
group SMTP email template, it is similar to Context Posts
which we removed and is unnecessary.
This PR also removes the link to staged user profiles in
the email; their email addresses will just be converted
to regular mailto: links.
This PR makes several changes to the group SMTP email contents to make it look more like a support inbox message.
* Remove the context posts, they only add clutter to the email and replies
* Display email addresses of staged users instead of odd generated usernames
* Add a "please reply above this line" message to sent emails
This PR backtracks a fair bit on this one https://github.com/discourse/discourse/pull/13220/files.
Instead of sending the group SMTP email for each user via `UserNotifications`, we are changing to send only one email with the existing `Jobs::GroupSmtpEmail` job and `GroupSmtpMailer`. We are changing this job and mailer along with `PostAlerter` to make the first topic allowed user the `to_address` for the email and any other `topic_allowed_users` to be the CC address on the email. This is to cut down on emails sent via SMTP, which is subject to daily limits from providers such as Gmail. We log these details in the `EmailLog` table now.
In addition to this, we have changed `PostAlerter` to no longer rely on incoming email email addresses for sending the `GroupSmtpEmail` job. This was unreliable as a user's email could have changed in the meantime. Also it was a little overcomplicated to use the incoming email records -- it is far simpler to reason about to just use topic allowed users.
This also adds a fix to include cc_addresses in the EmailLog.addressed_to_user scope.
* FEATURE: Staff can receive pending user reminders more frequently.
We now express the "pending_users_reminder_delay" in minutes instead of hours so staff can have finer control over the delay.
We need to keep in mind that the reminders could still take up to 20 minutes, even when using a lower value. We send them from a scheduled job.
* Migrate to a new site setting for the reminders delay
ATM it only implements server side of it, as my need is for automation purposes. However it should probably be added in the UI too as it's unexpected to have pinned_until and no bannered_until.
When we call Bookmark.cleanup! we want to make sure that
topic_user.bookmarked is updated for topics linked to the
bookmarks that were deleted. Also when PostDestroyer calls
destroy and recover. We have a job for this already --
SyncTopicUserBookmarked -- so we just utilize that.
Leaking state and non-obvious order (before :all runs *before* RailsHelper.test_setup) are not worth it.
A replacement PR for #13370. Fixes some flaky specs, e.g.
```
bin/rspec './spec/components/freedom_patches/translate_accelerator_spec.rb[1:3]' './spec/jobs/clean_up_user_export_topics_spec.rb[1:1]' --tag ~type:multisite --seed 35994
```
Also included:
* DEV: No need for locale reset (we do it anyway in rails_helper in `test_setup`)
Using 1 as the default value is confusing for some people as low-score flags are hidden unless staff uses the "(any)" priority filter. Let's change it to 0 and let every site adjust the setting to match their needs.
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
Email change requests are never deleted no matter if they completed
successfully or not. The abandoned requests have the disadvantage of
showing up as unconfirmed emails in user's preferences page.
Recalculating a ReviewableFlaggedPost's score after rejecting or ignoring it sets the score as 0, which means that we can't find them after reviewing. They don't surpass the minimum priority threshold and are hidden.
Additionally, we only want to use agreed flags when calculating the different priority thresholds.
* FEATURE: add support for like webhooks
Add support for like webhooks. Webhook events only send on user membership
in the defined webhook group filters.
This also fixes group webhook events, as before this was never used, and
the logic was not correct.
This filter hides reviewables with a score lower than the "reviewable_low_priority_threshold" setting. We only use reviewables that already met this threshold to calculate the Medium and High priority filters.
It used to check if an upload record exists, which is wrong because an
invalid upload record exists even if the upload was not created.
The other improvement is a better log message.
Previously watched words ignored topic titles when applying auto tagging rules.
Also copy has been improved to reflect how the system behaves.
The text hints that we are only watching first post now
When posts are moved from one topic to another, the `topic_user.bookmarked` column for all users in the new and the old topic needs to be resynced, for example because a user bookmarks post 12 in topic 1, then it is moved to topic 2, the topic_user record for topic 1 should no longer be bookmarked. A background job has been added to sync the column for a specified topic, or for no topic at all, which does it for all topics like the migration.
Also includes a migration that we have run in the past to fix bad data.

This has been addressed in other places in the past:
https://github.com/discourse/discourse/pull/10211https://github.com/discourse/discourse/pull/10188
We introduced a cap on the number of bookmarks the user can add in be145ccf2f. However this has caused unintended side effects; when the `jobs/scheduled/bookmark_reminder_notifications.rb` runs we get this error for users who already had more bookmarks than the limit:
> Job exception: Validation failed: Sorry, you have too many bookmarks, visit #{url}/my/activity/bookmarks to remove some.
This is because the `clear_reminder!` call was triggering a bookmark validation, which raised an error because the user already had to many, holding up other reminders.
This PR also adds `max_bookmarks_per_user` hidden site setting (default 2000). This replaces the BOOKMARK_LIMIT const so we can raise it for certain sites.
When bulk inviting, the uploaded CSV file may contain wrong values for
the user fields. This tries to automatically correct them by finding
the most similar option (by ignoring the case).
Admins can use bulk invites to pre-populate user fields. The imported
CSV file must have a header with "email" column (first position) and
names of the user fields (exact match).
Under the hood, the bulk invite will create staged users and populate
the user fields of those.
The user mailing list mode continued to be silently enabled and
UserEmail job checked just that ignoring site setting
disable_mailing_list_mode.
An additional migrate was added to set disable_mailing_list_mode
to false if any users enabled the mailing list mode already.
Currently the process of adding a custom image to badge is quite clunky; you have to upload your image to a topic, and then copy the image URL and pasting it in a text field. Besides being clucky, if the topic or post that contains the image is deleted, the image will be garbage-collected in a few days and the badge will lose the image because the application is not that the image is referenced by a badge.
This commit improves that by adding a proper image uploader widget for badge images.
It was used both when inviting from a topic page and when creating
invites with "Send to topic on first login", while it should be used
only in the former case.
Onebox content may only be resolved during the process_post job. Onebox content could change the content of the excerpt, so we need to make sure the excerpt is updated accordingly.
* FIX: Reduce the time_read threshold to one minute.

Completing the discobot tutorial gives you ~3m of reading time, so we set the limit at 5m. Additionally, we use an "OR" clause to cover the case when you just scroll through a single topic.
Previously when inheriting category auto-close settings for a topic, those settings were disrupted if another topic timer was assigned or if a topic was closed then manually re-opened.
This PR makes it so that when a topic is manually re-opened the topic auto-close settings are inherited from the category. However, they will now be based on the topic created_at date. As an example, for a topic with a category auto close hours setting of 72 (3 days):
* Topic was created on 2021-02-15 08:00
* Topic was closed on 2021-02-16 10:00
* Topic was opened again on 2021-02-17 06:00
Now, the topic will inherit the auto close timer again and will close automatically at **2021-02-18 08:00**, which is based on the creation date. If the current date and time is greater than the original auto-close time (e.g. we were at 2021-02-20 13:45) then no auto-close timer is created.
Note, this will not happen if the topic category auto-close setting is "based on last post".
Original PR was reverted because of broken migration https://github.com/discourse/discourse/pull/12058
I fixed it by adding this line
```
AND topics.id IN(SELECT id FROM topics ORDER BY created_at DESC LIMIT :max_new_topics)
```
This time it is left joining a limited amount of topics. I tested it on few databases and it worked quite smooth
Follow up https://github.com/discourse/discourse/pull/11968
Dismiss all new topics using the same DismissTopicService. In addition, MessageBus receives exact topic ids which should be marked as `seen`.
The bug was mentioned on meta https://meta.discourse.org/t/users-are-seeing-handling-of-unhandled-tag-again/155367
It was related to users who are watching a specific topic. In that case, when the hidden tag was added or removed to the topic they were notified by `NotifyTagChangeJob`.
That job should take hidden tags into consideration. If all changed tags are in a hidden group, it should exclude user not belong to that group.
At the same time, if visible to anyone tag is added or removed users watching topic should be notified.
The 'Discourse SSO' protocol is being rebranded to DiscourseConnect. This should help to reduce confusion when 'SSO' is used in the generic sense.
This commit aims to:
- Rename `sso_` site settings. DiscourseConnect specific ones are prefixed `discourse_connect_`. Generic settings are prefixed `auth_`
- Add (server-side-only) backwards compatibility for the old setting names, with deprecation notices
- Copy `site_settings` database records to the new names
- Rename relevant translation keys
- Update relevant translations
This commit does **not** aim to:
- Rename any Ruby classes or methods. This might be done in a future commit
- Change any URLs. This would break existing integrations
- Make any changes to the protocol. This would break existing integrations
- Change any functionality. Further normalization across DiscourseConnect and other auth methods will be done separately
The risks are:
- There is no backwards compatibility for site settings on the client-side. Accessing auth-related site settings in Javascript is fairly rare, and an error on the client side would not be security-critical.
- If a plugin is monkey-patching parts of the auth process, changes to locale keys could cause broken error messages. This should also be unlikely. The old site setting names remain functional, so security-related overrides will remain working.
A follow-up commit will be made with a post-deploy migration to delete the old `site_settings` rows.
This PR allows entering a float value for topic timers e.g. 0.5 for 30 minutes when entering hours, 0.5 for 12 hours when entering days. This is achieved by adding a new column to store the duration of a topic timer in minutes instead of the ambiguous both hours and days that it could be before.
This PR has ommitted the post migration to delete the duration column in topic timers; it will be done in a subsequent PR to ensure that no data is lost if the UPDATE query to set duration_mintues fails.
I have to keep the old keyword of duration in set_or_create_topic_timer for backwards compat, will remove at a later date after plugins are updated.
This is a try to simplify logic around dismiss new topics to have one solution to work in all places - dismiss all-new, dismiss new in a specific category or even in a specific tag.
This PR revamps the topic timer UI, using the time shortcut selector from the bookmark modal.
* Fixes an issue where the duration of hours/days after last reply or auto delete replies was not enforced to be > 0
* Fixed an issue where the timer dropdown options were not reloaded correctly if the topic status changes in the background (use `MessageBus` to publish topic state in the open/close timer jobs)
* Moved the duration input and the "based on last post" option from the `future-date-input` component, as it was only used for topic timers. Also moved out the notice that is displayed which was also only relevant for topic timers.
Lots of changes but it's mostly a refactoring.
The interesting part that was fix are the 'load_problem_<model>_ids' methods.
They will now return records with no search data associated so they can be properly indexed for the search.
This "bad" state usually happens after a migration.
Improvements to make console access to IncomingEmail more pleasant, and stopping certain IMAP logs from landing in the DB because they just create too much noise,
This should make it easier to track down how the incoming email was created, which is one of four locations:
The POP3 poller (which picks up reply via email replies)
The admin email controller #handle_mail (which is where hosted mail is sent)
The IMAP sync tool
The group SMTP mailer, which sends emails when replying to IMAP topics, pre-emptively creating IncomingEmail records to avoid double syncing
Moves the topic timer jobs from being scheduled ahead of time with enqueue_at to a 5 minute scheduled run like bookmark reminders, in a new job called Jobs::EnqueueTopicTimers. Backwards compatibility is maintained by checking if an existing topic timer job is enqueued in sidekiq for the timer, and if it is not running it inside the new job.
The functionality to close/open a topic if it is in the opposite state still remains in the after_save block of TopicTimer, with further commentary, which is used for Open/Close Temporarily.
This also removes the ensure_consistency! functionality of topic timers as it is no longer needed; the new job will always pick up the timers because they are not stored in a fragile state of sidekiq.
This adds a safe default to not process pop3 emails when the pop3 polling option is set up that are > 1 week old. This is to avoid the situation where an older mailbox is used, which causes us to go and process all emails in that mailbox, sending out error emails to the senders of emails which cannot be parsed successfully.
Splits the `ToggleTopicClosed` job into two distinct `OpenTopic` and `CloseTopic` jobs to make the code clearer. The old job cannot be deleted yet because of outstanding sidekiq schedules, so a todo has been added to do so later this year.
Also replaced mentions of `topic_status_update` with `topic_timer` in some files, because the `topic_status_update` model is obsolete and replaced by topic timer.
Added some shortcut methods for checking if a topic is open/whether a user can change an open topic.
Fixes a rare race condition causing the `Imap::Sync` class to create an incoming email and associated post/topic, which then kicks off the PostAlerter to notify others in the PM about a reply in the topic, but for the OP which is not necessary (because the person emailing the IMAP inbox already knows about the OP). Basically, we should never be sending the group SMTP email for the first post in a topic.
Also in this PR:
* Custom attribute accessors for the to/from/cc addresses on `IncomingEmail`, to parse them from an array to a joined string so the logic for this is only in one place.
* Store extra detail against the `IncomingEmail` created in `GroupSmtpMailer`
* regex test Mail header Reply-To as string instead of Field, which fixes `warning: deprecated Object#=~ is called on Mail::Field; it always returns nil`
* Add DEBUG_IMAP to log all IMAP logs as warnings for easier debugging
* Changed the Rails logging to `ImapSyncLog` in the `GroupSmtpMailer`
osts from topics with 'auto delete replies timer' with more than
skip_auto_delete_reply_likes likes will no longer be deleted. If 0,
all posts will be deleted.
My initial implementation didn't consider this case. We should skip imported users if the "imported_id" field is present, even if there're other custom fields.
This commit is dedicated to https://twitter.com/FiloSottile/status/1335666583126073354 for reminding me that like timestamps are valuable data.
Likes additionally include the topic_id and post_number of the acted post, to aid in analysis. Flag export does not include the disposition by staff.
When jobs are enqueued inside a transaction, it's possible that they will be executed before the necessary data is available in the database. This commit ensures all jobs are enqueued in an ActiveRecord after_commit hook.
One potential downside here is if the job fails to enqueue, the transaction will no longer be aborted. However, the chance of that happening is reasonably low, and the impact is significantly lower than the current issue where jobs are scheduled before their data is ready.
This commit adds an additional find_user_by_email hook to ManagedAuthenticator so that GitHub login can continue to support secondary email addresses
The github_user_infos table will be dropped in a follow-up commit.
This is the last core authenticator to be migrated to ManagedAuthenticator 🎉
When the linked topic is created we'll not hardcode the topic title and
let onebox work its magic instead so that the title can be updated
automatically.
- IgnoredUser records should all now have an expiring_at value. This commit enforces that in the DB, and fixes any corrupt rows
- Changes to the ignored user list are now handled by the `/u/{username}/notification_level` endpoint. This allows setting expiration dates on the ignore. This commit removes the old logic for saving a list of usernames in the user preferences.
- Many specs were calling `IgnoredUser.create`. This commit changes them to use `Fabricate(:ignored_user)` for consistency
This commit adds a site setting `auto_close_topics_create_linked_topic`
which when enabled works in conjunction with `auto_close_topics_post_count`
setting and creates a new linked topic for the topic just closed.
The auto-created new topic contains a link for all the previous topics
and the topic titles are appended with `(Part {n})`.
The setting is enabled by default.
There is a site setting reply_by_email_enabled which when combined with reply_by_email_address creates a Reply-To header in emails in the format "test+%{reply_key}@test.com" along with a PostReplyKey record, so when replying Discourse knows where to route the reply.
However this conflicts with the IMAP implementation. Since we are sending the email for a group via SMTP and from their actual email account, we want all replys to go to that email account as well so the IMAP sync job can pick them up and put them in the correct place. So if the group has IMAP enabled and configured, then the reply-to header will be correct.
This PR also makes a further fix to 64b0b50 by using the correct recipient user for the PostReplyKey record. If the post user is used we encounter this error:
if destination.user_id != user.id && !forwarded_reply_key?(destination, user)
raise ReplyUserNotMatchingError, "post_reply_key.user_id => #{destination.user_id.inspect}, user.id => #{user.id.inspect}"
end
This is because the user above is found from the from_address, but the destination which is the PostReplyKey is made by the post.user, which will be different people.
Our Email::Sender class accepts an optional user argument, which is used to create a PostReplyKey record when present. This record is used to sub out the %{reply_key} placeholder in the Reply-To mail header, so if we do not pass in the user we get a broken Reply-To header.
This is especially problematic in the IMAP group SMTP situation, because these emails go to customers that we are replying to, and when they reply to us the email bounces! This fixes the issue by passing user to the Email::Sender when sending a group_smtp email but there is still more to do in another PR.
This Email::Sender optional user is a bit of a footgun IMO, especially because most of the time we use it there is a user we can source. I would like to do another PR for this after this one to make the parameter not optional, so we don't end up with these reply issues down the line again.
Dependency on gifsicle, allow_animated_avatars and allow_animated_thumbnails
site settings were all removed. Animated GIF images are still allowed, but
the generated optimized images are no longer animated for those (which were
used for avatars and thumbnails).
The added 'animated' is populated by extracting information using FastImage.
This field was used to selectively reoptimize old animations. This process
happens in the background.
Previously, Jobs::EnqueueDigestEmails would enqueue a digest job for every user, even if there are no topics to send. The digest job would exit, no email would send, and last_emailed_at would not change. 30 minutes later, Jobs::EnqueueDigestEmails would run again and re-enqueue jobs for the same users.
120fa8ad introduced a temporary mitigation for this issue, by randomly selecting a subset of those users each time.
This commit adds a new `digest_attempted_at` column to the `user_stats` table. This column is updated every time a digest job completes for a user. Using this, we can avoid scheduling digest jobs for the same user every 30 minutes. This also removes the random user selection in 120fa8ad, and instead prioritizes users who had digests attempted the longest time ago.
To avoid blocking the sidekiq queue a limit of 10,000 digests per 30 minutes
is introduced.
This acts as a safety measure that makes sure we don't keep pouring oil on
a fire.
On multisites it is recommended to set the number way lower so sites do not
dominate the backlog. A reasonable default for multisites may be 100-500.
This can be controlled with the environment var
DISCOURSE_MAX_DIGESTS_ENQUEUED_PER_30_MINS_PER_SITE
See https://meta.discourse.org/t/changing-a-users-email/164512 for additional context.
Previously when an admin user changed a user's email we assumed that they would need a password reset too because they likely did not have access to their account. This proved to be incorrect, as there are other reasons a user needs admin to change their email. This PR:
* Changes the admin change email for user flow so the user is sent an email to confirm the change
* We now record who the email change request was requested by
* If the requested by user is admin and not the user we note this in the email sent to the user
* We also make the confirm change email route open to anonymous users, so it can be clicked by the user even if they do not have access to their account. If there is a logged in user we make sure the confirmation matches the current user.
* FEATURE: Export the entire user profile as json, not just bio/website
* FEATURE: Add session log information to user export
Even though the columns are named 'auth_token' etc, the content is not actually usable to log into the forum with. Despite all that, it is still truncated for export, to avoid any 'token hash cracking' situations.
Extracted commonly used spec helpers into spec/support/uploads_helpers.rb, removed unused stubs and let definitions. Makes it easier to write new S3-related specs without copy and pasting setup steps from other specs.
This PR removes the user reminder topic timers, because that system has been supplanted and improved by bookmark reminders. The option is removed from the UI and all existing user reminder topic timers are migrated to bookmark reminders.
Migration does this:
* Get all topic_timers with status_type 5 (reminders)
* Gets all bookmarks where the user ID and topic ID match
* Loops through the found topic timers
* If there is no bookmark for the OP of the topic, then we just create a bookmark with a reminder
* If there is a bookmark for the OP of the topic and it does **not** have a reminder set, then just
update it with the topic timer reminder
* If there is a bookmark for the OP of the topic with a reminder then just discard the topic timer
* Cancels all outstanding user reminder topic timers
* **Trashes (not deletes) all user reminder topic timers**
Notes:
* For now I have left the user reminder topic timer job class in place; this is so the jobs can be cancelled in the migration. It and the specs will be deleted in the next PR.
* At a later date I will write a migration to delete all trashed user topic timers. They are not deleted here in case there are data issues and they need to be recovered.
* A future PR will change the UI of the topic timer modal to make it look more like the bookmark modal.
