This required some interface changes (mostly changing Laravel's or
Symfony's request and response classes to those of Zend's Diactoros.
Some smaller changes to the execution flow in a few of the abstract
action base classes, but nothing substantial.
Note: The request and response classes are immutable, so we usually
need to return new instances after modifying the old ones.
This will be able to dispatch PSR-7-style requests to any callback
that returns a proper response object.
Largely based on my original work for FluxBB 2.0.
Originally the user activity feed was implemented using UNIONs. I was
looking at make an API to add activity “sources”, or extra UNION
queries (select from posts, mentions, etc.) but quickly realised that
this is too slow and there’s no way to make it scale.
So I’ve implemented an API which is very similar to how notifications
work (see previous commit). The `activity` table is an aggregation of
stuff that happens, and it’s kept in sync by an ActivitySyncer which is
used whenever a post it created/edited/deleted, a user is
mentioned/unmentioned, etc.
Again, the API is very simple (see Core\Activity\PostedActivity +
Core\Handlers\Events\UserActivitySyncer)
It turns out that the idea of “sending” a notification is flawed. (What
happens if the notification subject is deleted shortly after? The
notified user would end up with a dud notification which would be
confusing. What about if a post is edited to mention an extra user? If
you sent out notifications, the users who’ve already been mentioned
would get a duplicate notification.)
Instead, I’ve introduced the idea of notification “syncing”. Whenever a
change is made to a piece of data (e.g. a post is created, edited, or
deleted), you make a common notification and “sync” it to a set of
users. The users who’ve received this notification before won’t get it
again. It will be sent out to new users, and hidden from users who’ve
received it before but are no longer recipients (e.g. users who’ve been
“unmentioned” in a post).
To keep track of this, we use the existing notifications database
table, with an added `is_deleted` column. The syncing/diffing is
handled all behind the scenes; the API is extremely simple (see
Core\Notifications\DiscussionRenamedNotification +
Core\Events\Handlers\DiscussionRenamedNotifier)
For now I’ve chucked it on Flarum\Core as a static method, but
ultimately I think we will need a ConfigRepository abstraction (whether
it replaces or sits underneath the Flarum\Core static method I’m not
sure).
Also starting to think about multisite scenarios, I think this is
important. The Forum model could actually end up with a database table
behind it, and each forum would have its own config settings? Haven’t
really thought about it too hard yet…
- Automatically serialise the attribute
- Apply Permissible grant callbacks
Need to consider splitting the $permission property into two arguments
(currently have to explode by ‘.’)
- The recipient(s) are the concern of the notifier/sender, not the
notification itself
- Allow “retraction” of notifications (e.g. if a discussion is
stickied, but then it is unstickied)
- Misc. cleanup
Perhaps also in user activity stream. They are used in the mentions
extension.
In order to generate the excerpt, each formatter can implement a
“strip” method which basically converts block formatting into inline
formatting.
For example: when you rename a discussion, DiscussionRenamedPost is
created. If you rename it again immediately afterwards, then a new
DiscussionRenamedPost can be merged into the old one. This will either
result in the old one being updated with the new title, or it being
deleted all together if it was renamed back to the old title.
Also make some tweaks:
- Merge SerializeAction::$include and
SerializeAction::$includeAvailable into a keyed boolean array
- Set defaults for SerializeAction::$limit and $limitMax
- Rename SerializeAction::$sortAvailable to $sortFields
- An API action handles a Flarum\Api\Request, which is a simple object
containing an array of params, the actor, and optionally an HTTP
request object
- Most API actions use SerializeAction as a base, which parses request
input according to the JSON-API spec (creates a JsonApiRequest object),
runs the child class method to get data, then serializes it and assigns
it to a JsonApiResponse (standard HTTP response with a
Tobscure\JsonApi\Document as content)
- The JSON-API request input parsing is subject to restrictions as
defined by public static properties on the action (i.e. extensible)
- Also the actor is given to the serializer instance now, instead of
being a static property
This is useful for both the Sticky and Categories extensions, where if
you sticky a discussion and then immediately unsticky it, or if you
move it to a category and then immediately move it back, the last
“activity” post will be removed.
- In order to be consistent with the Ember/LESS naming scheme, renamed
Flarum\Web to Flarum\Forum.
- Moved common classes into Flarum\Support so that Flarum\Admin doesn’t
depend on Flarum\Forum. Also moved Actor into Flarum\Support as it
doesn’t belong in the domain.
- Extract shared Ember components into a “flarum-common” ember-cli
addon. This can be used by both the forum + admin Ember apps, keeping
things DRY
- Move LESS styles into their own top-level directory and do a similar
thing (extract common styles)
- Add LESS/JS compilation and versioning to PHP (AssetManager)
- Set up admin entry point
(Theoretical) upgrade instructions:
- Delete everything in [app_root]/public
- Set up tooling in forum/admin Ember apps (npm install/update, bower
install/update) and then build them (ember build)
- php artisan vendor:publish
- Upgrade flarum/flarum repo (slight change in a config file)
- If you need to trigger a LESS/JS recompile, delete the .css/.js files
in [app_root]/public/flarum. I set up LiveReload to do this for me when
I change files in less/ or ember/
Todo:
- Start writing admin app!
- Remove bootstrap/font-awesome from repo and instead depend on their
composer packages? Maybe? (Bower is not an option here)
- Notifications can be delivered in multiple ways (alert, email)
- Different notification types can implement interfaces to allow
themselves to be delivered in these various ways
- User preferences for each notification type/method combination are
automatically registered
This is so that if an extension adds a post type, and the database gets
populated with posts of that type, but then if the extension is
disabled, we wouldn’t want those posts to display because we would have
no knowledge about how to deal with/render them.
Addresses the following error when using pqsql.
[PDOException]
SQLSTATE[42703]: Undefined column: 7 ERROR: column "comment" does not exist
LINE 1: ...d) FROM posts WHERE user_id = users.id and type = "comment")
This allows me to override the handle() method in subclasses (where
I need access to the request object) without having to overwrite
run(), too.
The class is still abstract.
Perhaps this should be an extension, but it is pretty essential and I
can’t think of many instances where it wouldn’t be wanted. Would be
very easy to extract later on if need be.
New stuff:
- Signup + email confirmation.
- Updated authentication strategy with remember cookies. closes#5
- New search system with some example gambits! This is cool - check out
the source. Fulltext drivers will be implemented as decorators
overriding the EloquentPostRepository’s findByContent method.
- Lay down the foundation for bootstrapping the Ember app.
- Update Web layer’s asset manager to properly publish CSS/JS files.
- Console commands to run installation migrations and seeds.
Refactoring:
- New structure: move models, repositories, commands, and events into
their own namespaces, rather than grouping by entity.
- All events are classes.
- Use L5 middleware and command bus implementations.
- Clearer use of repositories and the Active Record pattern.
Repositories are used only for retrieval of ActiveRecord objects, and
then save/delete operations are called directly on those ActiveRecords.
This way, we don’t over-abstract at the cost of Eloquent magic, but
testing is still easy.
- Refactor of Web layer so that it uses the Actions routing
architecture.
- “Actor” concept instead of depending on Laravel’s Auth.
- General cleanup!
Whenever a user registers or changes their email, they are sent an
email containing a link which they must click to confirm it.
Upon registering, a user won’t be assigned to any groups and therefore
won’t have permission to do anything (but they can still log in!) Upon
confirming their email for the first time, their account will be
assigned to the Member group and thus “activated”.
Record when the discussion was renamed, from what, and by whom.
Information is stored in the `content` field as a serialised JSON
object because proper polymorphism will be too difficult with Ember
Data and especially when extensions try to add new post types.
Laravel’s remember_token is tied to the session/cookies, which we don’t
need as the API is stateless. It makes much more sense to use our own
token mechanism.
MyISAM doesn’t support transactions which is problematic for testing.
Will have to consider this more carefully when working on FULLTEXT
search, but for now I just wanna test!
(Sorry about the retrograde migration changes, but I figure it isn’t
problematic at this stage because we can just reseed. It’s nice to keep
things clean as long as we can!)
JSON-API specifies that multiple resources should be fetched with a
comma-separated list of IDs, i.e. discussions/1,2,3,4. But this is
problematic because if we do a findQuery with only one ID, then a
single object will come back from the API where the serializer is
expecting an array containing a single object.
Instead, I’ve just implemented an ids “filter” on the discussions index
API route (which is the default way that the adapter finds multiple
IDs.)
