This commit addresses an issue for sites where secure_uploads
is turned on after the site has been operating without it for
some time.
When uploads are linked when they are used inside a post,
we were setting the access_control_post_id unconditionally
if it was NULL to that post ID and secure_uploads was true.
However this causes issues if an upload has been used in a
few different places, especially if a post was previously
used in a PM and marked secure, so we end up with a case of
the upload using a public post for its access control, which
causes URLs to not use the /secure-uploads/ path in the post,
breaking things like image uploads.
We should only set the access_control_post_id if the post is the first time the
upload is referenced so it cannot hijack uploads from other places.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_tag_topics site setting to tag_topic_allowed_groups.

This isn't used by any of our plugins or themes, so very little fallout.

The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
* FIX: Secure upload post processing race condition
This commit fixes a couple of issues.
A little background -- when uploads are created in the composer
for posts, regardless of whether the upload will eventually be
marked secure or not, if secure_uploads is enabled we always mark
the upload secure at first. This is so the upload is by default
protected, regardless of post type (regular or PM) or category.
This was causing issues in some rare occasions though because
of the order of operations of our post creation and processing
pipeline. When creating a post, we enqueue a sidekiq job to
post-process the post which does various things including
converting images to lightboxes. We were also enqueuing a job
to update the secure status for all uploads in that post.
Sometimes the secure status job would run before the post process
job, marking uploads as _not secure_ in the background and changing
their ACL before the post processor ran, which meant the users
would see a broken image in their posts. This commit fixes that issue
by always running the upload security changes inline _within_ the
cooked_post_processor job.
The other issue was that the lightbox wrapper link for images in
the post would end up with a URL like this:
```
href="/secure-uploads/original/2X/4/4e1f00a40b6c952198bbdacae383ba77932fc542.jpeg"
```
Since we weren't actually using the `upload.url` to pass to
`UrlHelper.cook_url` here, we weren't converting this href to the CDN
URL if the post was not in a secure context (the UrlHelper does not
know how to convert a secure-uploads URL to a CDN one). Now we
always end up with the correct lightbox href. This was less of an issue
than the other one, since the secure-uploads URL works even when the
upload has become non-secure, but it was a good inconsistency to fix
anyway.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the require_topic_approval and require_reply_approval from custom fields to the new CategorySetting model.
This PR is nearly identical to #20580, which migrated num_auto_bump_daily, but since these are slightly more sensitive, they are moved after the previous one is verified.
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.
Not all revisions involve changes to the actual post/topic content. We
may want to know if a revisions includes the topic title or post raw.
Specifically introducing these for use in the Akismet plugin to
conditionally queue checks.
* FIX: Displaying the wrong number of minimum tags in the composer
When the minimum number of tags set for the category is larger than the minimum number of tags
set in the category tag-groups, the composer was displaying the wrong value.
This commit fixes the value displayed in the composer to show the max value between the required
for the category and the tag-groups set for the category.
This bug was reported on Meta in https://meta.discourse.org/t/tags-from-multiple-tag-groups-required-only-suggest-select-at-least-one-tag/263817
* FIX: Limiting tags in categories not working as expected
When a category was restricted to a tag group A, which was set to only allow
one tag from the group per topic, selecting a tag belonging only to A returned
other tags from A that also belonged to other group/s (if any).
Example:
Tag group A: alpha, beta, gamma, epsilon, delta
Tag group B: alpha, beta, gamma
Both tag groups set to only allow one tag from the group per topic.
If Category 1 was set to only allow tags from the tag group A, and the first tag
selected was epsilon, then, because they also belonged to tag group B, the tags
alpha, beta, and gamma were still returned as valid options when they should not be.
This commit ensures that once a tag from a tag group that restricts its tags to
one per topic is selected, no other tag from this group is returned.
This bug was reported on Meta in https://meta.discourse.org/t/limiting-tags-to-categories-not-working-as-expected/263143.
* FIX: Moving topics does not prompt to add required tag for new category
When a topic moved from a category to another, the tag requirements
of the new category were not being checked.
This allowed a topic to be created and moved to a category:
- that limited the tags to a tag group, with the topic containing tags
not allowed.
- that required N tags from a tag group, with the topic not containing
the required tags.
This bug was reported on Meta in https://meta.discourse.org/t/moving-tagged-topics-does-not-prompt-to-add-required-tag-for-new-category/264138.
* FIX: Editing topics with tag groups from parents allows incorrect tagging
When there was a combination between parent tags defined in a tag group
set to allow only one tag from the group per topic, and other tag groups
relying on this restriction to combine the children tag types with the
parent tag, editing a topic could allow the user to insert an invalid
combination of these tags.
Example:
Automakers tag group: landhover, toyota
- group set to limit one tag from the group per topic
Toyota models group: land-cruiser, hilux, corolla
Landhover models group: evoque, defender, discovery
If a topic was initially set up with the tags toyota, land-cruiser it was
possible to edit it by removing the tag toyota and adding the tag landhover
and other landhover model tags like evoque for example.
In this case, the topic would end up with the tags toyota, land-cruiser,
landhover, evoque because Discourse will automatically insert the
missing parent tag toyota when it detects the tag land-cruiser.
This combination of tags would violate the restriction specified in
the Automakers tag group resulting in an invalid combination of tags.
This commit enforces that the "one tag from the group per topic"
restriction is verified before updating the topic tags and also
make sure the verification checks the compatibility of parent tags that
would be automatically inserted.
After the changes, the user will receive an error similar to:
The tags land-cruiser, landhover cannot be used simultaneously.
Please include only one of them.
- 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
What is the problem?
Consider the following timeline:
1. OP starts a topic.
2. Troll responds snarkily.
3. Flagger flags the post as “inappropriate”.
4. Admin agrees and hides the post.
5. Troll ninja-edits the post within the grace period, but still snarky.
6. Flagger flags the post as inappropriate again.
The current behaviour is that the flagger is met with an error saying the post has been reviewed and can't be flagged again for the same reason.
The desired behaviour is after someone has edited a post, it should be flaggable again.
Why is this happening?
This is related to the ninja-edit feature, where within a set grace period no new revision is created, but a new revision is required to flag the same post for the same reason.
So essentially there is a window between the naughty corner cooldown where a flagged post can't be edited, and the ninja-edit grace period, where an edit can be made without a new revision. Posts that are edited within this window can't be re-flagged by the same user.
|-----------------|-------------------------------|
^ Flag accepted | ~~~~~~~~~~~~~ 🥷🏻 ~~~~~~~~~~~~ |
| ^ Editing grace period over
^ Naughty corner cooldown over
How does this fix it?
We already create a new revision when ninja-editing a post with a pending flag. The issue above happens only in the case where the flag is already accepted.
This change extends the existing behaviour so that a new revision is created when ninja-editing any flagged post, regardless of the status of the flag. (Deleted flags excluded.)
This should also help with posterity, avoiding situations where a successfully flagged post looks innocuous in the history because it was ninja-edited, and vice versa.
When revising a post, if the topic that post belonged to did not have a category attached it would error with
> NoMethodError (undefined method `read_restricted' for nil:NilClass)
This adds a SiteSetting, which when enabled, creates a small_action post for tag/category changes to the topic. It uses `topic.add_moderator_post, and passes raw text in, to describe the change.
This will be used by plugins to handle the client side of their custom
post validations without having to overwrite the whole composer save
action as it was done in other plugins.

When PostRevisor is called with 'skip_validations: true' it can save
the post twice and one of the calls passes the correct 'validate: false'
argument, but the other one does not.
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
* FIX: hide welcome topic banner as soon as the welcome topic is edited
This commit adds a message bus listener on client to hide the welcome
topic banner as soon as the welcome topic is edited.
* update test
* only subscribe when show_welcome_topic_banner is true
* Do not lookup for messageBus service if it's not required
* Remove unneeded code
* Cache result for Site.show_welcome_topic_banner
* Update tests per latest changes
* Changes per PR review
All other tests that are setting grade_period use either unitless `0`, `1.minute` or `5.minutes` so it wasn't clear if `5` was meant to be seconds (it was)
Tag edit notifications are either created by PostActionNotifier or
PostRevisor. PostActionNotifier already checks if the site setting is
enabled. but PostRevisor scheduled a NotifyTagChange job without
checking disable_tags_edit_notifications.

Previously we only supported a single 'required tag group' for a category. This commit allows admins to specify multiple required tag groups, each with their own minimum tag count.
A new category_required_tag_groups database table replaces the existing columns on the categories table. Data is automatically migrated.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
This commit handles the edge case where a draft is lost with no warnings if the user edits the title (or category/tags) of a topic while they're replying.to the same topic. Repro steps are as follows:
1. Start replying to a topic and type enough to get a draft saved.
2. Scroll up to the topic title and click the pencil icon next to the topic title, change the title, category and/or tags, and then save the changes.
3. Reload the page and you'll see that the draft is gone.
This happens because we only allow 1 draft per topic per user and when you edit the title of a topic that you're replying to, from the server perspective it'll look like as if you've submitted your reply so it will advance the draft sequence for the topic and delete the draft.
The fix in this commit makes `PostRevisor` skip advancing the draft sequence when a topic's title is edited using the pencil button next to the title.
