When invoking e.g. `can_see?(Foo.new)`, the guardian checks if there's a method `#can_see_foo?` defined and if so uses that to determine whether the user can see it or not.
When such a method is not defined, the guardian currently returns `true`, but it is probably a better call (pun intended) to make it "safe by default" and return `false` instead. I.e. if you can't explicitly see it, you can't see it at all.
This change makes the change to `Guardian#can_see?` to fall back to `false` if no visibility check method is defined.
For `#can_see_user?` and `#can_see_tag?` we don't have any particular logic that prevents viewing. We previously relied on the implicit `true` value, but since that's now change to `false`, I have explicitly implemented these two methods in `UserGuardian` and `TagGuardian` modules. If in the future we want to add some logic for it, this would be the place.
To be clear, **the behaviour remains the same**, but the `true` value is now explicit rather than implicit.
* FIX: do not notify admins on suppressed categories
Avoid notifying admins on categories where they are not explicitly members
in cases where SiteSetting.suppress_secured_categories_from_admin is
enabled.
This helps keep notification stream clean and avoids admins mistakenly
being invited to discussions that should be suppressed
If a secure upload's access_control_post was trashed, and an anon user
tried to look at that upload, they would get a 500 error rather than
the correct 403 because of an error inside the PostGuardian logic.
* DEV: Remove enable_whispers site setting
Whispers are enabled as long as there is at least one group allowed to
whisper, see whispers_allowed_groups site setting.
* DEV: Always enable whispers for admins if at least one group is allowed.
Currently, moderators are able to set primary group for users
irrespective of the of the `moderators_manage_categories_and_groups` site
setting value.
This change updates Guardian implementation to honour it.
Since the system user is a regular user, it can have its
`allow_private_messages` user option turned off, which
with our current `can_send_private_message?(Discourse.system_user)`
check inside the CurrentUserSerializer, will prevent any
user from sending messages in the UI if the system user is not
accepting PMs.
This commit adds a new `can_send_private_messages?` method to
the Guardian, which can be used in serializers and not depend
on the system user. When the user actually sends a message
we still rely on the old `can_send_private_message?(target)`
call to see if they are allowed to send the message to the target.
The new method is just to say they can "generally" send
private messages.
Before this commit, there was no way for us to efficiently check an
array of topics for which a user can see. Therefore, this commit
introduces the `TopicGuardian#can_see_topic_ids` method which accepts an
array of `Topic#id`s and filters out the ids which the user is not
allowed to see. The `TopicGuardian#can_see_topic_ids` method is meant to
maintain feature parity with `TopicGuardian#can_see_topic?` at all
times so a consistency check has been added in our tests to ensure that
`TopicGuardian#can_see_topic_ids` returns the same result as
`TopicGuardian#can_see_topic?`. In the near future, the plan is for us
to switch to `TopicGuardian#can_see_topic_ids` completely but I'm not
doing that in this commit as we have to be careful with the performance
impact of such a change.
This method is currently not being used in the current commit but will
be relied on in a subsequent commit.
Building does not persist the object in the database which is
unrealistic since we're mostly dealing with persisted objects in
production.
In theory, this will result our test suite taking longer to run since we
now have to write to the database. However, I don't expect the increase
to be significant and it is actually no different than us adding new
tests which fabricates more objects.
Staged users are allowed to view topics they created in a read restricted category
when category has `Category#email_in` and
`Category#email_in_allow_strangers` configured.

This PR also makes it so `bot` (negative ID) and `system` users are always allowed
to send PMs, since the old conditional was just based on `enable_personal_messages`
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
This will replace `enable_personal_messages` and
`min_trust_to_send_messages`, this commit introduces
the setting `personal_message_enabled_groups`
and uses it in all places that `enable_personal_messages`
and `min_trust_to_send_messages` currently apply.
A migration is included to set `personal_message_enabled_groups`
based on the following rules:
* If `enable_personal_messages` was false, then set
`personal_message_enabled_groups` to `3`, which is
the staff auto group
* If `min_trust_to_send_messages` is not default (1)
and the above condition is false, then set the
`personal_message_enabled_groups` setting to
the appropriate auto group based on the trust level
* Otherwise just set `personal_message_enabled_groups` to
11 which is the TL1 auto group
After follow-up PRs to plugins using these old settings, we will be
able to drop the old settings from core, in the meantime I've added
DEPRECATED notices to their descriptions and added them
to the deprecated site settings list.
This commit also introduces a `_map` shortcut method definition
for all `group_list` site settings, e.g. `SiteSetting.personal_message_enabled_groups`
also has `SiteSetting.personal_message_enabled_groups_map` available,
which automatically splits the setting by `|` and converts it into
an array of integers.
* FIX: Do not allow to remove like if topic is archived
* FIX: Always show like button
The like button used to be hidden if the topic was archived and it had
no likes. This commit changes that to always show the like button, but
with a not-allowed cursor if the topic is archived.
* FIX: don't memoize site setting in guardian
Memoizing site settings can make tests more fragile and harder to debug

The "everyone" group is an automatic group and GroupUser records do not
exist for it. This commit allows all users if the group everyone is one
of the groups in the setting "pm_tags_allowed_for_groups".
Before, whispers were only available for staff members.
Config has been changed to allow to configure privileged groups with access to whispers. Post migration was added to move from the old setting into the new one.
I considered having a boolean column `whisperer` on user model similar to `admin/moderator` for performance reason. Finally, I decided to keep looking for groups as queries are only done for current user and didn't notice any N+1 queries.
We have not used anything related to bookmarks for PostAction
or UserAction records since 2020, bookmarks are their own thing
now. Deleting all this is just cleaning up old cruft.
If a group's messageable_level is set to nobody then staff can't should not be able to send PMs to it.

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.
