This method is a huge footgun in production, since it calls
the Redis KEYS command. From the Redis documentation at
https://redis.io/commands/keys/:
> Warning: consider KEYS as a command that should only be used in
production environments with extreme care. It may ruin performance when
it is executed against large databases. This command is intended for
debugging and special operations, such as changing your keyspace layout.
Don't use KEYS in your regular application code.
Since we were only using `delete_prefixed` in specs (now that we
removed the usage in production in 24ec06ff85)
we can remove this and instead rely on `use_redis_snapshotting` on the
particular tests that need this kind of clearing functionality.
Communities can use sidebar or header dropdown, therefore navigation menu is a better name settings in 2 places:
- Old user sidebar preferences;
- Site setting about default tags and categories.
Currently, groups owned by moderators are not visible to them on the
groups page. This happens because, the group visibility queries don't
account for non-admin staff user group ownership.
This change updates the group visibility scope queries to account for a
moderator(non-admin staff user) group ownership.
This patch sets some limits on custom fields:
- an entity can’t have more than 100 custom fields defined on it
- a custom field can’t hold a value greater than 10,000,000 characters
The current implementation of custom fields is relatively complex and
does an upsert in SQL at some point, thus preventing to simply add an
`ActiveRecord` validation on the custom field model without having to
rewrite a part of the existing logic.
That’s one of the reasons this patch is implementing validations in the
`HasCustomField` module adding them to the model including the module.
* FEATURE: reduce avatar sizes to 6 from 20
This PR introduces 3 changes:
1. SiteSetting.avatar_sizes, now does what is says on the tin.
previously it would introduce a large number of extra sizes, to allow for
various DPIs. Instead we now trust the admin with the size list.
2. When `avatar_sizes` changes, we ensure consistency and remove resized
avatars that are not longer allowed per site setting. This happens on the
12 hourly job and limited out of the box to 20k cleanups per cycle, given
this may reach out to AWS 20k times to remove things.
3.Our default avatar sizes are now "24|48|72|96|144|288" these sizes were
very specifically picked to limit amount of bluriness introduced by webkit.
Our avatars are already blurry due to 1px border, so this corrects old blur.
This change heavily reduces storage required by forums which simplifies
site moves and more.

This commit adds modifiers that allow plugins to change how categories and groups are prefetched into the application and listed in the respective controllers.
Possible use cases:
- prevent some categories/groups from being prefetched when the application loads for performance reasons.
- prevent some categories/groups from being listed in their respective index pages.
When a user chooses to move a topic/message to an existing topic/message, they can now opt to merge the posts chronologically (using a checkbox in the UI).
What is this change required?
I noticed that actions in `SidebarSectionsController` resulted in
lots of N+1 queries problem and I wanted a solution to
prevent such problems without having to write N+1 queries tests. I have
also used strict loading for `SidebarSection` queries in performance
sensitive spots.
Note that in this commit, I have also set `config.active_record.action_on_strict_loading_violation = :log`
for the production environment so that we have more visibility of
potential N+1 queries problem in the logs. In development and test
environment, we're sticking with the default of raising an error.
This patch is a followup of
https://github.com/discourse/discourse/pull/21504 where limits on custom
message for an invite were introduced.
This had a side effect of making some existing invites invalid and with
the current code, they can’t be invalidated anymore.
This patch takes the approach of skipping the validations when invites
are invalidated since the important thing here is to mark the invite as
invalidated regardless of its actual state in the DB. (no other
attributes are updated at the same time anyway)
Comparing arrays without an explicit order or sort is usually a bad idea and leads to flakiness. It also replaces `#sort` calls in a couple of specs with array specific matchers like `contain_exactly` and `match_array`.
In addition to that it switches the arguments of some expectations around, because it should be `expect(actual).to eq(expected)` instead of `expect(expected).to eq(actual)`
* FIX: Video thumbnails can have duplicates
It's possible that a duplicate video or even a very similar video could
generate the same video thumbnail. Because video thumbnails are mapped
to their corresponding video by using the video sha1 in the thumbnail
filename we need to allow for duplicate thumbnails otherwise even when a
thumbnail has been generated for a topic it will not be mapped
correctly.
This will also allow you to re-upload a video on the same topic to
regenerate the thumbnail.
* fix typo
The old method updated only existing records, without considering that
new tags might have been created or some tags might not exist anymore.
This was usually not a problem because the stats were also updated by
other code paths.
However, the ensure consistency job should be more solid and help when
other code paths fail or after importing data.
Also, update category tag stats too should happen when updating other
category stats as well.
- Update welcome topic copy
- Edit the welcome topic automatically when the title or description changes
- Remove “Create your Welcome Topic” banner/CTA
- Add "edit welcome topic" user tip
### Background
When SSRF detection fails, the exception bubbles all the way up, causing a log alert. This isn't actionable, and should instead be ignored. The existing `rescue` does already ignore network errors, but fails to account for SSRF exceptions coming from `FinalDestination`.
### What is this change?
This PR does two things.
---
Firstly, it introduces a common root exception class, `FinalDestination::SSRFError` for SSRF errors. This serves two functions: 1) it makes it easier to rescue both errors at once, which is generally what one wants to do and 2) prevents having to dig deep into the class hierarchy for the constant.
This change is fully backwards compatible thanks to how inheritance and exception handling works.
---
Secondly, it rescues this new exception in `UserAvatar.import_url_for_user`, which is causing sporadic errors to be logged in production. After this SSRF errors are handled the same as network errors.
This fixes a bug in the create invite API where if you passed in an
integer for the group_ids field it would fail to add the user to the
specified group.
The current limit (250 characters) is too low, as we have some
translations used for our badge descriptions that result in a
description length of 264 characters.
To be on the safe side, the limit is now set to 500 characters.
This amends it so our cached counting reliant specs run in synchronize mode
When running async there are situations where data is left over in the table
after a transactional test. This means that repeat runs of the test suite
fail.
* DEV: move sidebar community section to database
Before, community section was hard-coded. In the future, we are planning to allow admins to edit it. Therefore, it has to be moved to database to `custom_sections` table.
Few steps and simplifications has to be made:
- custom section was hidden behind `enable_custom_sidebar_sections` feature flag. It has to be deleted so all forums, see community section;
- migration to add `section_type` column to sidebar section to show it is a special type;
- migration to add `segment` column to sidebar links to determine if link should be displayed in primary section or in more section;
- simplify more section to have one level only (secondary section links are merged);
- ensure that links like `everything` are correctly tracking state;
- make user an anonymous links position consistence. For example, from now on `faq` link for user and anonymous is visible in more tab;
- delete old community-section template.
SearchIndexer is only automatically disabled in `before_all` and `before` blocks which means at the start
of test runs. Enabling the SearchIndexer in one `fab!` block will affect
all other `fab!` blocks which is not ideal as we may be indexing stuff
for search when we don't need to.
Many blog posts use these to illustrate and images were previously omitted
Additionally strip superfluous HTML and BODY tags from embed HTML.
This was incorrectly returned from server.
Group user event webhooks filtered by group fail silently
because the `group_ids` job arg wasn't being passed into the job.
This change add's `group_ids` to the `EmitWebHookEvent` jobs queued for
`user_added_to_group` and `user_removed_from_group` events.
Currently, only user badge grants emit webhook events. This change
extends the `user_badge` webhook to emit user badge revocation events.
A new `user_badge_revoked` event has been introduced instead of relying
on the existing `user_badge_removed` event. `user_badge_removed` emitted
just the `badge_id` and `user_id` which aren't helpful for generating a
meaningful webhook payload for revoked(deleted) user badges.
The new event emits the user badge object.
* FIX: Do not overwrite existing thumbnails
When auto generating video thumbnails they should not overwrite any
existing topic thumbnails.
This also addresses an issue with capitalized file extensions like .MOV
that were being excluded.
* Update app/models/post.rb

This fixes a 500 error that occurs when adding a tag to a category's
restricted tag list if the category's restricted tags already included a
synonym tag.
This feature will allow sites to define which emoji are not allowed. Emoji in this list should be excluded from the set we show in the core emoji picker used in the composer for posts when emoji are enabled. And they should not be allowed to be chosen to be added to messages or as reactions in chat.
This feature prevents denied emoji from appearing in the following scenarios:
- topic title and page title
- private messages (topic title and body)
- inserting emojis into a chat
- reacting to chat messages
- using the emoji picker (composer, user status etc)
- using search within emoji picker
It also takes into account the various ways that emojis can be accessed, such as:
- emoji autocomplete suggestions
- emoji favourites (auto populates when adding to emoji deny list for example)
- emoji inline translations
- emoji skintones (ie. for certain hand gestures)
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`.
