Constants should always be only assigned once. The logical OR assignment
of a constant is a relic of the past before we used zeitwerk for
autoloading and had bugs where a file could be loaded twice resulting in
constant redefinition warnings.
The `id` column of `notifications` table and `notification_id` columns
of the other tables have been migrated to bigint in previous commits
(for example, 799a45a).
In order to run the migrations with zero downtime, the data had to be
copied to new columns and swapped, but the old columns have been kept
to allow for rollback. They are no longer needed now.
* Add migrations to ensure password hash is synced across users & user_passwords
* Persist password-related data in user_passwords instead of users
* Merge User#expire_old_email_tokens with User#expire_tokens_if_password_changed
* Add post deploy migration to mark password-related columns from users table as read-only
* Refactored UserPassword#confirm_password? and changes required to accommodate hashing the password after validations
Anonymous users are "shadow" users created when an existing real user desires to post anonymously. This feature is off by default, but it can be enabled via the `allow_anonymous_posting` site setting. Those shadow users shouldn't be included in the users directory (`/u`).
This upgrade is designed to be fully backwards-compatible. Any icon names which have changed will be automatically remapped to the new name. For now, this will happen silently. In future, once core & official themes/plugins have been updated, we will start raising deprecation errors to help theme/plugin authors update their code.

Our old group SMTP SSL option was a checkbox,
but this was not ideal because there are actually
3 different ways SSL can be used when sending
SMTP:
* None
* SSL/TLS
* STARTTLS
We got around this before with specific overrides
for Gmail, but it's not flexible enough and now people
want to use other providers. It's best to be clear,
though it is a technical detail. We provide a way
to test the SMTP settings before saving them so there
should be little chance of messing this up.
This commit also converts GroupEmailSettings to a glimmer
component.
Allow admin to create custom flag which requires an additional message.
I decided to rename the old `custom_flag` into `require_message` as it is more descriptive.

We previously migrated field_type from a string to an integer backed enum. Part of this involved renaming a column in a post migration, swapping out field_type:string for field_type:integer. This borks the ActiveRecord cache since the application is already running. Rebooting fixes it, but we want to avoid having this happen in the first place.
Follow up to: #27444. In that PR we added a new integer column for UserField#field_type and populated the data based on the old text field.
In this PR we drop the old text column and swap in the new integer (enum) column.
In #22851 we added a dependent strategy for deleting upload references when a draft is destroyed. This, however, didn't catch all cases, because we still have some code that issues DELETE drafts queries directly to the database. Specifically in the weekly cleanup job handled by Draft#cleanup!.
This PR fixes that by turning the raw query into an ActiveRecord #destroy_all, which will invoke the dependent strategy that ultimately deletes the upload references. It also includes a post migration to clear orphaned upload references that are already in the database.
Since we just released 3.2, this is a good time to drop deprecated columns. This is a two-phase process. First we drop the columns, then we remove the ignored_columns declarations. Because of that I'm batching all deprecated columns for dropping here first. Once a full deploy is done we remove the declarations.
We just completed the 3.2 release, which marks a good time to drop some previously deprecated columns.
Since the column has been marked in ignored_columns, it has been inaccessible to application code since then. There's a tiny risk that this might break a Data Explorer query, but given the nature of the column, the years of disuse, and the fact that such a breakage wouldn't be critical, we accept it.
Fixes the migration in 8c6144d116
which was unconditionally enabling the new admin sidebar for admins
if they ever changed the old setting `enable_admin_sidebar_navigation`,
even if they changed it to false.
* DEV: Auto link video placeholder posts

Adds a migration to auto-link any video placeholder posts so that upload
references will be created.

We were seeing lots of deadlocks deploying this migration. This improves
the situation in 2 ways.
1. ddl transaction is avoided, so we hold locks for far shorter times
2. we operate in chunks of a maximum of 100_000 posts (though it is heavily filtered down)
* improve code so it is clearer
Previously, Discourse's password hashing was hard-coded to a specific algorithm and parameters. Any changes to the algorithm or parameters would essentially invalidate all existing user passwords.
This commit introduces a new `password_algorithm` column on the `users` table. This persists the algorithm/parameters which were use to generate the hash for a given user. All existing rows in the users table are assumed to be using Discourse's current algorithm/parameters. With this data stored per-user in the database, we'll be able to keep existing passwords working while adjusting the algorithm/parameters for newly hashed passwords.
Passwords which were hashed with an old algorithm will be automatically re-hashed with the new algorithm when the user next logs in.
Values in the `password_algorithm` column are based on the PHC string format (https://github.com/P-H-C/phc-string-format/blob/master/phc-sf-spec.md). Discourse's existing algorithm is described by the string `$pbkdf2-sha256$i=64000,l=32$`
To introduce a new algorithm and start using it, make sure it's implemented in the `PasswordHasher` library, then update `User::TARGET_PASSWORD_ALGORITHM`.
That column is obsolete since we added the `granted_title_badge_id` column in 2019 (56d3e29a69). Having both columns can lead to inconsistencies (mostly due to old data from before 2019).
For example, `BadgeGranter.revoke_ungranted_titles!` doesn't work correctly if `badge_granted_title` is `false` while `granted_title_badge_id` points to the badge that is used as title.
Currently we don’t have an association between reviewables and posts.
This sometimes leads to inconsistencies in the DB as a post can have
been deleted but an associated reviewable is still present.
This patch addresses this issue simply by adding a new association to
the `Post` model and by using the `dependent: :destroy` option.
Currently, `Tag#topic_count` is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user has not excess to. We classify this as a minor leak in sensitive information.
The following changes are introduced in this commit:
1. Introduce `Tag#public_topic_count` which only count topics which have been tagged with a given tag in public categories.
2. Rename `Tag#topic_count` to `Tag#staff_topic_count` which counts the same way as `Tag#topic_count`. In other words, it counts all topics tagged with a given tag regardless of the category the topic is in. The rename is also done so that we indicate that this column contains sensitive information.
3. Change all previous spots which relied on `Topic#topic_count` to rely on `Tag.topic_column_count(guardian)` which will return the right "topic count" column to use based on the current scope.
4. Introduce `SiteSetting.include_secure_categories_in_tag_counts` site setting to allow site administrators to always display the tag topics count using `Tag#staff_topic_count` instead.
In Discourse, there are many migration files where we CREATE INDEX CONCURRENTLY which requires us to set disable_ddl_transaction!. Setting disable_ddl_transaction! in a migration file runs the SQL statements outside of a transaction. The implication of this is that there is no ROLLBACK should any of the SQL statements fail.
We have seen lock timeouts occuring when running CREATE INDEX CONCURRENTLY. When that happens, the index would still have been created but marked as invalid by Postgres.
Per the postgres documentation:
> If a problem arises while scanning the table, such as a deadlock or a uniqueness violation in a unique index, the CREATE INDEX command will fail but leave behind an “invalid” index. This index will be ignored for querying purposes because it might be incomplete; however it will still consume update overhead.
> The recommended recovery method in such cases is to drop the index and try again to perform CREATE INDEX CONCURRENTLY . (Another possibility is to rebuild the index with REINDEX INDEX CONCURRENTLY ).
When such scenarios happen, we are supposed to either drop and create the index again or run a REINDEX operation. However, I noticed today that we have not been doing so in Discourse. Instead, we’ve been incorrectly working around the problem by checking for the index existence before creating the index in order to make the migration idempotent. What this potentially mean is that we might have invalid indexes which are lying around in the database which PG will ignore for querying purposes.
This commits adds a migration which queries for all the
invalid indexes in the `public` namespace and reindexes them.
This commit promotes all post_deploy migrations which existed in
Discourse v2.8.0 (timestamp <= 20220107014925).
This commit includes a fix to the promote_migrations script to promote
all migrations of the first version of the previous stable version. For
example, if the current stable version is v2.8.13, the version used as
a cutoff for promoting migrations is v2.8.0.

See https://meta.discourse.org/t/discourse-email-messages-are-incorrectly-threaded/233499
for thorough reasoning.
This commit changes how we generate Message-IDs and do email
threading for emails sent from Discourse. The main changes are
as follows:
* Introduce an outbound_message_id column on Post that
is either a) filled with a Discourse-generated Message-ID
the first time that post is used for an outbound email
or b) filled with an original Message-ID from an external
mail client or service if the post was created from an
incoming email.
* Change Discourse-generated Message-IDs to be more consistent
and static, in the format `discourse/post/:post_id@:host`
* Do not send References or In-Reply-To headers for emails sent
for the OP of topics.
* Make sure that In-Reply-To is filled with either a) the OP's
Message-ID if the post is not a direct reply or b) the parent
post's Message-ID
* Make sure that In-Reply-To has all referenced post's Message-IDs
* Make sure that References is filled with a chain of Message-IDs
from the OP down to the parent post of the new post.
We also are keeping X-Discourse-Post-Id and X-Discourse-Topic-Id,
headers that we previously removed, for easier visual debugging
of outbound emails.
Finally, we backfill the `outbound_message_id` for posts that have
a linked `IncomingEmail` record, using the `message_id` of that record.
We do not need to do that for posts that don't have an incoming email
since they are backfilled at runtime if `outbound_message_id` is missing.
It's already included in the `ignored_columns` list in the group model. 03ffb0bf27/app/models/group.rb (L9)
Also, removed the `MigrateGroupFlairImages` onceoff job and spec.
At some point in the past we decided to rename the 'regular' notification state of topics/categories to 'normal'. However, some UI copy was missed when the initial renaming was done so this commit changes the spots that were missed to the new name.

This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.
No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.
There is no need to wait until after the deploy for this cleanup. In fact, running it later will mean there could be a window of a few minutes during which the site is broken.
The only requirement is that it runs after the broken `20220401130745_create_category_required_tag_groups` migration.
