Configuring staged users to watch categories and tags is a way to sign
them up to get many emails. These emails may be unwanted and get marked
as spam, hurting the site's email deliverability.
Users can opt-in to email notifications by logging on to their
account and configuring their own preferences.
If staff need to be able to configure these preferences on behalf of
staged users, the "allow changing staged user tracking" site setting
can be enabled. Default is to not allow it.

There was a bug with changing timestamps using the topic wrench button. Under some circumstances, a topic was disappearing from the top of the latest tab after changing timestamps. Steps to reproduce:
- Choose a topic on the latest tab (the topic should be created some time ago, but has recent posts)
- Change topic timestamps (for example, move them one day forward):
- Go back to the latest tab and see that topic has disappeared.
This PR fixes this. We were setting topic.bumped_at to the timestamp user specified on the modal. This is incorrect. Instead, we should be setting topic.bumped_at to the created_at timestamp of the last regular (not a whisper and so on) post on the topic.
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.
User flair was given by user's primary group. This PR separates the
two, adds a new field to the user model for flair group ID and users
can select their flair from user preferences now.
For other private messages we have the site setting
personal_email_time_window_seconds (default 20s) which allows
people to edit their post etc. before the email is sent.
This PR makes the Jobs::GroupSmtpEmail enqueuer in the
PostAlerter use the same delay.
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
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.
The generated regular expressions did not contain \b which matched
every text that contained the word, even if it was only a substring of
a word.
For example, if "art" was a watched word a post containing word
"artist" matched.
Subclasses must call #delete_user_actions inside build_actions to support user deletion. The method adds a delete user bundle, which has a delete and a delete + block option. Every subclass is responsible for implementing these actions.
Notifying about a tag change sometimes resulted in loading a large
number of users in memory just to perform an exclusion. This commit
prefers to do inclusion (i.e. instead of exclude users X, do include
users in groups Y) and does it in SQL to avoid fetching unnecessary
data that is later discarded.
When a group only has SMTP enabled and not IMAP, we do not
want to enqueue the :group_smtp_email job because using the group's
SMTP credentials for sending user_private_message emails is
handled by the UserNotifications class.
We do not want the :group_smtp_email job to be enqueued because
that uses a reply key instead of the group.email_username
for the reply-to address which is not what we want for SMTP
only, and also creates an IncomingEmail record to prevent IMAP
double syncing which we do not need either.
There is an open question about what happens when IMAP is
enabled after SMTP has been enabled for a while, and also questions
around whether we could do away with :group_smtp_email altogether
and handle everything via EmailLog and UserNotifications, adding
additional columns to the former and modifying the Imap::Sync
class to take this into account...a lot more further testing
for IMAP needs to be done to answer those questions.
For now, this fix should be sufficient to get the correct
reply-to address for user_private_response messages sent in
response to emails sent directly to the group's
email_username SMTP address.

This PR changes the `UserNotification` class to send outbound `user_private_message` using the group's SMTP settings, but only if:
* The first allowed_group on the topic has SMTP configured and enabled
* SiteSetting.enable_smtp is true
* The group does not have IMAP enabled, if this is enabled the `GroupSMTPMailer` handles things
The email is sent using the group's `email_username` as both the `from` and `reply-to` address, so when the user replies from their email it will go through the group's SMTP inbox, which needs to have email forwarding set up to send the message on to a location (such as a hosted site email address like meta@discoursemail.com) where it can be POSTed into discourse's handle_mail route.
Also includes a fix to `EmailReceiver#group_incoming_emails_regex` to include the `group.email_username` so the group does not get a staged user created and invited to the topic (which was a problem for IMAP), as well as updating `Group.find_by_email` to find using the `email_username` as well for inbound emails with that as the TO address.
#### Note
This is safe to merge without impacting anyone seriously. If people had SMTP enabled for a group they would have IMAP enabled too currently, and that is a very small amount of users because IMAP is an alpha product, and also because the UserNotification change has a guard to make sure it is not used if IMAP is enabled for the group. The existing IMAP tests work, and I tested this functionality by manually POSTing replies to the SMTP address into my local discourse.
There will probably be more work needed on this, but it needs to be tested further in a real hosted environment to continue.
It was not clear that replace watched words can be used to replace text
with URLs. This introduces a new watched word type that makes it easier
to understand.
This overhauls the user interface for the group email settings management, aiming to make it a lot easier to test the settings entered and confirm they are correct before proceeding. We do this by forcing the user to test the settings before they can be saved to the database. It also includes some quality of life improvements around setting up IMAP and SMTP for our first supported provider, GMail. This PR does not remove the old group email config, that will come in a subsequent PR. This is related to https://meta.discourse.org/t/imap-support-for-group-inboxes/160588 so read that if you would like more backstory.
### UI
Both site settings of `enable_imap` and `enable_smtp` must be true to test this. You must enable SMTP first to enable IMAP.
You can prefill the SMTP settings with GMail configuration. To proceed with saving these settings you must test them, which is handled by the EmailSettingsValidator.
If there is an issue with the configuration or credentials a meaningful error message should be shown.
IMAP settings must also be validated when IMAP is enabled, before saving.
When saving IMAP, we fetch the mailboxes for that account and populate them. This mailbox must be selected and saved for IMAP to work (the feature acts as though it is disabled until the mailbox is selected and saved):
### Database & Backend
This adds several columns to the Groups table. The purpose of this change is to make it much more explicit that SMTP/IMAP is enabled for a group, rather than relying on settings not being null. Also included is an UPDATE query to backfill these columns. These columns are automatically filled when updating the group.
For GMail, we now filter the mailboxes returned. This is so users cannot use a mailbox like Sent or Trash for syncing, which would generally be disastrous.
There is a new group endpoint for testing email settings. This may be useful in the future for other places in our UI, at which point it can be extracted to a more generic endpoint or module to be included.
Previously we would retry push notifications indefinitely for all errors
except for ExpiredSubscription
Under certain conditions other persistent errors may arise such as a persistent
rate limit.
If we track more than 3 errors in a period of time longer than a day we will
delete the subscription
Also performs a bit of internal cleanup to ensure protected methods really
are private.
This PR improves the UI of bulk select so that its context is applied to the Dismiss Unread and Dismiss New buttons. Regular users (not just staff) are now able to use topic bulk selection on the /new and /unread routes to perform these dismiss actions more selectively.
For Dismiss Unread, there is a new count in the text of the button and in the modal when one or more topic is selected with the bulk select checkboxes.
For Dismiss New, there is a count in the button text, and we have added functionality to the server side to accept an array of topic ids to dismiss new for, instead of always having to dismiss all new, the same as the bulk dismiss unread functionality. To clean things up, the `DismissTopics` service has been rolled into the `TopicsBulkAction` service.
We now also show the top Dismiss/Dismiss New button based on whether the bottom one is in the viewport, not just based on the topic count.
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
Watched words are always regular expressions, despite watched_words_
_regular_expressions being enabled or not. Internally, wildcard
characters are replaced with a regular expression that matches any non
whitespace character.
* FIX: Hide tag watched words if tagging is disabled
These 'autotag' words were shown even if tagging was disabled.
* FIX: Make autotag watched words case insensitive
This commit also fixes the bug when no tag was applied if no other tag
was already present.
We have a few places in the code where we need to validate various email related settings, and will have another soon with the improved group email settings UI. This PR introduces a class which can validate POP3, IMAP, and SMTP credentials and also provide a friendly error message for issues if they must be presented to an end user.
This PR does not change any existing code to use the new service. I have added a TODO to change POP3 validation and the email test rake task to use the new validator post-release.
* FIX: Link notification to first unread post
If a topic with a few posts was posted in a watched category or with a
watched tag, the created notification would always point to the last
post, instead of pointing to the first one.
The root cause is that the query that fetched the first unread post
uses 'TopicUser' records and those are not created by default for
user watching a category or tag. In this case, it should use the
'CategoryUser' or 'TagUser' records.
* DEV: Use named bind variables
The message in logs will now look like:
```
BadgeGranter::GrantError: Failed to backfill 'Some Badge' badge: {:post_ids=>[]}. Reason: ERROR: column "email" does not exist
LINE 6: ...t id as user_id, current_timestamp as granted_at, email from...
```
When the admin creates a new custom field they can specify if that field should be searchable or not.
That setting is taken into consideration for quick search results.
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
Rails 6.1.3.1 deprecates a few API and has some internal changes that break our tests suite, so this commit fixes all the deprecations and errors and now Discourse should be fully compatible with Rails 6.1.3.1. We also have a new release of the rails_failover gem that's compatible with Rails 6.1.3.1.
This PR adds a new category setting which is a column in the `categories` table, `allow_unlimited_owner_edits_on_first_post`.
What this does is:
* Inside the `can_edit_post?` method of `PostGuardian`, if the current user editing a post is the owner of the post, it is the first post, and the topic's category has `allow_unlimited_owner_edits_on_first_post`, then we bypass the check for `LimitedEdit#edit_time_limit_expired?` on that post.
* Also, similar to wiki topics, in `PostActionNotifier#after_create_post_revision` we send a notification to all users watching a topic when the OP is edited in a topic with the category setting `allow_unlimited_owner_edits_on_first_post` enabled.
This is useful for forums where there is a Marketplace or similar category, where topics are created and then updated indefinitely by the OP rather than the OP making new topics or additional replies. In a way this acts similar to a wiki that only one person can edit.
To add an extra layer of security, we sanitize settings before shipping them to the client. We don't sanitize those that have the "html" type.
The CookedPostProcessor already uses Loofah for sanitization, so I chose to also use it for this. I added it to our gemfile since we installed it as a transitive dependency.
Count errors on updating themes in the error bucket. Otherwise,
there was a chance that this could hide errors eg, if a deploy key to a
private repo were to be deleted. Admins probably would like to know about this.
This PR allows invitations to be used when the DiscourseConnect SSO is enabled for a site (`enable_discourse_connect`) and local logins are disabled. Previously invites could not be accepted with SSO enabled simply because we did not have the code paths to handle that logic.
The invitation methods that are supported include:
* Inviting people to groups via email address
* Inviting people to topics via email address
* Using invitation links generated by the Invite Users UI in the /my/invited/pending route
The flow works like this:
1. User visits an invite URL
2. The normal invitation validations (redemptions/expiry) happen at that point
3. We store the invite key in a secure session
4. The user clicks "Accept Invitation and Continue" (see below)
5. The user is redirected to /session/sso then to the SSO provider URL then back to /session/sso_login
6. We retrieve the invite based on the invite key in secure session. We revalidate the invitation. We show an error to the user if it is not valid. An additional check here for invites with an email specified is to check the SSO email matches the invite email
7. If the invite is OK we create the user via the normal SSO methods
8. We redeem the invite and activate the user. We clear the invite key in secure session.
9. If the invite had a topic we redirect the user there, otherwise we redirect to /
Note that we decided for SSO-based invites the `must_approve_users` site setting is ignored, because the invite is a form of pre-approval, and because regular non-staff users cannot send out email invites or generally invite to the forum in this case.
Also deletes some group invite checks as per https://github.com/discourse/discourse/pull/12353
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.
We were sending 2 emails for user silencing if a message was provided in the UI. Also always send email for user silence and user suspend with reason regardless of whether message provided.
This commit includes other various improvements to watched words.
auto_silence_first_post_regex site setting was removed because it overlapped
with 'require approval' watched words.
Previously we were checking truthiness in some places, and `== true` in
others. That can lead to some inconsistent UX where the interface says
the email is valid, but account creation fails.
This commit ensures values are boolean when set, and raises an error for
other value types.
If this safety check is triggered, it means the specific auth provider
needs to be updated to pass booleans.
The bug was mentioned on meta: https://meta.discourse.org/t/pressing-dismiss-new-doesnt-clear-new-topics/179858
Problem is that sometimes the user has TopicUser records with `last_read_post_number` set as NULL. In that case, the topic is still "new" to them and should be dismissed when they click dismiss button.
In addition, I added that condition to post_migration and bumped the number to fix existing records. Migration is written to be idempotent so it will make no harm to already deployed instances.
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".
Updating a topic's visibility did not increase or decrease the
topic_count of a category, but Category.update_stats does ignore
unlisted topics which resulted in inconsistencies when deleting
such topics.
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`.
* FEATURE: Ability to dismiss new topics in a specific tag
Follow up of https://github.com/discourse/discourse/pull/11927
Using the same mechanism to disable new topics in a tag.
* FIX: respect when category and tag is selected
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 adds a new table UserNotificationSchedules which stores monday-friday start and ends times that each user would like to receive notifications (with a Boolean enabled to remove the use of the schedule). There is then a background job that runs every day and creates do_not_disturb_timings for each user with an enabled notification schedule. The job schedules timings 2 days in advance. The job is designed so that it can be run at any point in time, and it will not create duplicate records.
When a users saves their notification schedule, the schedule processing service will run and schedule do_not_disturb_timings. If the user should be in DND due to their schedule, the user will immediately be put in DND (message bus publishes this state).
The UI for a user's notification schedule is in user -> preferences -> notifications. By default every day is 8am - 5pm when first enabled.
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.
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.
Passes by_user to :user_unsilenced so plugins can detect whether or not
a silence was done automatically (by system user) or manually (by non-system)
Adds the ability to pass details in the action logger params so custom loggers
can pass their own details eg, in custom silence logs
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 🎉
- 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
The NewUserOfTheMonth badge is part of the Badges::GettingStarted group. This group is skipped in BadgeGranter if the user skips the new user tips. However, the NewUserOfTheMonth badge granter job does not account for this. Instead, it notifies the user they've received the badge even if they did not.
This commit introduces a simple fix to allow granting of this badge even to users who skipped the new user tips.
DEV: add plugin hooks for silence message parameters
Allows plugins to add, and update extra silence message params for custom
i18n vars
Allows plugins to override system messages via `message_title` and
`message_raw` parameters. We can later expose these params where necessary via event
hooks. Expose the parameter for the on user_silenced trigger.
Like "default watching" and "default tracking" categories option now the "regular" categories support is added. It will be useful for sites that are muted by default. The user option will be displayed only if `mute_all_categories_by_default` site setting is enabled.
* FIX: Unlike own posts on ownership transfer
If a user has liked a post that has passed the
`post_undo_action_window_mins` system setting window and you transfer ownership
of that post to that user you will be the owner of a post that you have
liked, but cannot unlike resulting in a weird UI behavior. This commit
fixes this issue.
The existing tests didn't check for the timeout window for unliking
posts so I added that in.
I couldn't find a good way to do this logic inside of the guardian class
so rather than duplicating behavior of the `PostActionDestroyer` class
inside of the `PostOwnerChanger` I decided to pass in a "bypass"
variable that could be used to check if the calling class is the
'post_owner_changer' and bypass the guardian instead. I went this route
because the guardian `can_delete_post_action` method has no way of
distinguishing how to allow a user to be able to unlike their own posts
after the timeout window but only on a post owner change.
* use an options hash instead
Enabling the moderators_manage_categories_and_groups site setting will allow moderator users to create/manage groups.
* show New Group form to moderators
* Allow moderators to update groups and read logs, where appropriate
* Rename site setting from create -> manage
* improved tests
* Migration should rename old log entries
* Log group changes, even if those changes mean you can no longer see the group
* Slight reshuffle
* RouteTo /g if they no longer have permissions to view group
* 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
In the near future, we will be swtiching to PG headlines to generate the
search blurb. As such, we need to replace audio and video links in the
raw data used for headline generation. This also means that we avoid
replacing links each time we need to generate the blurb.
* DEV: Show message when cannot invite user to PM
When inviting a user to a PM return a message that says, "Sorry, this
user can't be invited." if they have been muted or are not in a users
allowed pm users list.
* Minor refactor & improved some text
We do prefix matching in search so there is no need to inject the extra
terms.
Before:
```
"'discourse':10,11 'discourse.org':10,11 'org':10,11 'test':8A,10,11 'test.discourse.org':10,11 'titl':4A 'uncategor':9B"
```
After:
```

```
* FEATURE: Allow List for PMs
This feature adds a new user setting that is disabled by default that
allows them to specify a list of users that are allowed to send them
private messages. This way they don't have to maintain a large list of
users they don't want to here from and instead just list the people they
know they do want. Staff will still always be able to send messages to
the user.
* Update PR based on feedback
```
discourse_development=# SELECT alias, lexemes FROM TS_DEBUG('www.discourse.org');
alias | lexemes
-------+---------------------
host | {www.discourse.org}
discourse_development=# SELECT TO_TSVECTOR('www.discourse.org');
to_tsvector
-----------------------
'www.discourse.org':1
```
Given the above lexeme, we will inject additional lexeme by splitting
the host on `.`. The actual tsvector stored will look something like
```
tsvector
---------------------------------------
'discourse':1 'discourse.org':1 'org':1 'www':1 'www.discourse.org':1
```
There is a feature in search where we take over from the tokenizer
in postgres and attempt to inject more words into search.
So for example: sam.i.am will inject the words i and am.
This is not ideal cause there are many edge cases and this can
cause extreme index bloat.
This is an opening move commit to make it configurable, over the
next few weeks we will evaluate and decide if we disable this by
default or simply remove.
This reverts commit 20780a1eee.
