DEV: Allow passing cook_method to TopicEmbed.import to override default
This will be used in the rss-polling plugin when we want to have
oneboxes on feed content, like youtube for example.
Previously, a group's `default_notification_level` change will only affect the users added after it.

* DEV: Use named parameters for dir-span helper
Follow up to: e50a5c0c73
In order to improve code clarity this change introduces named parameters
for the dir-span helper. This is specifically for the new `htmlSafe`
parameter which you can use instead of just passing in a boolean if the
strings you are passing in have already been escaped.
Before: `{{dir-span category.description false}}`
After: `{{dir-span category.description htmlSafe=true}}`
* Set default value for params arg
The seed-fu gem resets the sequence on all the tables it touches. In some situations, this can cause primary keys to be re-used. This commit introduces a freedom patch which ensures seed-fu only touches the sequence when it is less than the id of one of the seeded records.
PresenceChannel aims to be a generic system for allow the server, and end-users, to track the number and identity of users performing a specific task on the site. For example, it might be used to track who is currently 'replying' to a specific topic, editing a specific wiki post, etc.
A few key pieces of information about the system:
- PresenceChannels are identified by a name of the format `/prefix/blah`, where `prefix` has been configured by some core/plugin implementation, and `blah` can be any string the implementation wants to use.
- Presence is a boolean thing - each user is either present, or not present. If a user has multiple clients 'present' in a channel, they will be deduplicated so that the user is only counted once
- Developers can configure the existence and configuration of channels 'just in time' using a callback. The result of this is cached for 2 minutes.
- Configuration of a channel can specify permissions in a similar way to MessageBus (public boolean, a list of allowed_user_ids, and a list of allowed_group_ids). A channel can also be placed in 'count_only' mode, where the identity of present users is not revealed to end-users.
- The backend implementation uses redis lua scripts, and is designed to scale well. In the future, hard limits may be introduced on the maximum number of users that can be present in a channel.
- Clients can enter/leave at will. If a client has not marked itself 'present' in the last 60 seconds, they will automatically 'leave' the channel. The JS implementation takes care of this regular check-in.
- On the client-side, PresenceChannel instances can be fetched from the `presence` ember service. Each PresenceChannel can be used entered/left/subscribed/unsubscribed, and the service will automatically deduplicate information before interacting with the server.
- When a client joins a PresenceChannel, the JS implementation will automatically make a GET request for the current channel state. To avoid this, the channel state can be serialized into one of your existing endpoints, and then passed to the `subscribe` method on the channel.
- The PresenceChannel JS object is an ember object. The `users` and `count` property can be used directly in ember templates, and in computed properties.
- It is important to make sure that you `unsubscribe()` and `leave()` any PresenceChannel objects after use
An example implementation may look something like this. On the server:
```ruby
register_presence_channel_prefix("site") do |channel|
next nil unless channel == "/site/online"
PresenceChannel::Config.new(public: true)
end
```
And on the client, a component could be implemented like this:
```javascript
import Component from "@ember/component";
import { inject as service } from "@ember/service";
export default Component.extend({
presence: service(),
init() {
this._super(...arguments);
this.set("presenceChannel", this.presence.getChannel("/site/online"));
},
didInsertElement() {
this.presenceChannel.enter();
this.presenceChannel.subscribe();
},
willDestroyElement() {
this.presenceChannel.leave();
this.presenceChannel.unsubscribe();
},
});
```
With this template:
```handlebars
Online: {{presenceChannel.count}}
<ul>
{{#each presenceChannel.users as |user|}}
<li>{{avatar user imageSize="tiny"}} {{user.username}}</li>
{{/each}}
</ul>
```
Uppy V2 includes the S3 multipart batch presigning change
we contributed in d613b849a6
so we need to upgrade it. This also brings both package.json
files into line and accounts for the renaming of Plugin
to BasePlugin in Uppy.
This has been tested and is working locally for both
regular Ember and Ember CLI, for uploads.json
XHR uploads and for direct S3 uploads (single and multipart).
This mixin needs to be shared between the composer and composer-like
user interfaces. This commit makes it so the events and the underlying
data model is configurable by the component extending the ComposerUploadUppy
mixin.
Also removes two MessageBus unsubscribe calls which were unnecessary.
The generate_presigned_put endpoint for direct external uploads
(such as the one for the uppy-image-uploader) records allowed
S3 metadata values on the uploaded object. We use this to store
the sha1-checksum generated by the UppyChecksum plugin, for later
comparison in ExternalUploadManager.
However, we were not doing this for the create_multipart endpoint,
so the checksum was never captured and compared correctly.
Also includes a fix to make sure UppyChecksum is the last preprocessor to run.
It is important that the UppyChecksum preprocessor is the last one to
be added; the preprocessors are run in order and since other preprocessors
may modify the file (e.g. the UppyMediaOptimization one), we need to
checksum once we are sure the file data has "settled".
The user-topic-list template is also in use in other places when we want to improve blank page syndrome, so this PR is a preparation for that changes as well.
