Checking `plugin.enabled?` while initializing plugins causes issues in two ways:
- An application restart is required for changes to take effect. A load-balanced multi-server environment could behave very weirdly if containers restart at different times.
- In a multisite environment, it takes the `enabled?` setting from the default site. Changes on that site affect all other sites in the cluster.
Instead, `plugin.enabled?` should be checked at runtime, in the context of a request. This commit removes `plugin.enabled?` from many `instance.rb` methods.
I have added a working `plugin.enabled?` implementation for methods that actually affect security/functionality:
- `post_custom_fields_whitelist`
- `whitelist_staff_user_custom_field`
- `add_permitted_post_create_param`
This feature can be enabled by choosing a destination for the
`shared drafts category` site setting.
* Staff members can create shared drafts, choosing a destination
category for the topic when it is published.
* Shared Drafts can be viewed in their category, or above the
topic list for the destination category where it will end up.
* When the shared draft is ready, it can be published to the
appropriate category by clicking a button on the topic view.
* When published, Drafts change their timestamps to the current
time, and any edits to the original post are removed.
Locking a post prevents it from being edited. This is useful if the user
has posted something which has been edited out, and the staff members don't
want them to be able to edit it back in again.
* Split alias levels in mentionable and messageable levels.
* Fixed some tests.
* Set messageable level to everyone by default.
* By defaults, groups are not mentionable or messageable.
* Made staff groups messageable by the system.
* Allow an (optional) post-creation time to be submitted.
This should allow a new post to be created with an initial
date/time specified by the caller, which will be useful for
people writing importers..
* Only allow `created_at` to be submitted via the API.
This addresses the previous concern.
