Figuring out what unread topics a user has is a very expensive
operation over time.
Users can easily accumulate 10s of thousands of tracking state rows
(1 for every topic they ever visit)
When figuring out what a user has that is unread we need to join
the tracking state records to the topic table. This can very quickly
lead to cases where you need to scan through the entire topic table.
This commit optimises it so we always keep track of the "first" date
a user has unread topics. Then we can easily filter out all earlier
topics from the join.
We use pg functions, instead of nested queries here to assist the
planner.
This feature introduces the concept of themes. Themes are an evolution
of site customizations.
Themes introduce two very big conceptual changes:
- A theme may include other "child themes", children can include grand
children and so on.
- A theme may specify a color scheme
The change does away with the idea of "enabled" color schemes.
It also adds a bunch of big niceties like
- You can source a theme from a git repo
- History for themes is much improved
- You can only have a single enabled theme. Themes can be selected by
users, if you opt for it.
On a technical level this change comes with a whole bunch of goodies
- All CSS is now compiled using a custom pipeline that uses libsass
see /lib/stylesheet
- There is a single pipeline for css compilation (in the past we used
one for customizations and another one for the rest of the app
- The stylesheet pipeline is now divorced of sprockets, there is no
reliance on sprockets for CSS bundling
- CSS is generated with source maps everywhere (including themes) this
makes debugging much easier
- Our "live reloader" is smarter and avoid a flash of unstyled content
we run a file watcher in "puma" in dev so you no longer need to run
rake autospec to watch for CSS changes
- avoid access denied on bad cookie, instead just nuke it
- avoid marking a token unseen for first minute post rotation
- log path in user auth token logs
Revamped system for managing authentication tokens.
- Every user has 1 token per client (web browser)
- Tokens are rotated every 10 minutes
New system migrates the old tokens to "legacy" tokens,
so users still remain logged on.
Also introduces weekly job to expire old auth tokens.
- Regular users are not notified of whispers
- Regular users no longer have "stuck" topics in unread
- Additional tracking for staff highest post number
- Remove a bunch of unused columns in topics table
previously we supported blanket read and write for user API, this
change amends it so we can define more limited scopes. A scope only
covers a few routes. You can not grant access to part of the site and
leave a large amount of the information hidden to API consumer.
FIX: warning about popup dimensions when using facebook login
Rules are:
- On account creation we always import
- If you already have an avatar uploaded, nothing is changed
- If you have no avatar uploaded, we upload from facebook on login
- If you have no avatar uploaded, we select facebook unless gravatar already selected
This also fixes SSO issues where on account creation accounts had missing avatar uploads
This feature ensures session cookie lifespan is extended
when user is online.
Also decreases session timeout from 90 to 60 days.
Ensures all users (including logged on ones) get expiring sessions.
Users can no longer opt-in for "public" edit history
if site owner disables it.
This feature adds cost and complexity to post rendering since
user options need to be premeptively loaded for every user in the
stream. It is also confusing to explain to communities with private edit
history.

We now optionally add a Variable Email Return Path to every email we send.
This allows us to cleanly handle email bounces, which in turn will improve
deliverability.
We no longer include previous replies as "context", instead
we include and excerpt of the post being replied to at the bottom
of notifications, this information was previously missing.
Users may opt in to emailing previous replies if they wish
or opt out of "in-reply-to" which makes sense in some email clients that
are smarter about displaying a tree of replies.
- always means we always send previous replies with every email
- never means we do not
- "unless previously sent" ... is the default, in which we only email you each reply once
The default_email_previous_replies site setting can control this toggle
This commit adds a new tracking table that lets us know
- When a migration ran
- What version Discourse was at
- How long it took
- What version Rails was at
The built in tracking in Rails is very limited, does not track this info
As it stands we load up user records quite frequently on the topic pages,
this in turn pulls all the columns for the users being selected, just to
discard them after they are loaded
New structure keeps all options in a discrete table, this is better organised
and allows us to easily add more column without worrying about bloating the
user table
UX: improve messaging so notifications list is far more stable
PERF: improve performance of notifcation lookup queries
- Add feature "SetTransientHeader" that allows shipping info to server
in the next Ajax request
- remove local storage hack used for notifications
- amend lookupStale to return hydrated objects, move logic into store
- stop magically clearing various notifications (likes, invitee accepted, group_summary, granted badge)
Messages are now in 3 buckets
- Inbox for all new messages
- Sent for all sent messages
- Archive for all messages you are done with
You can select messages from your Inbox or Sent and move them to your Archive,
you can move messages out of your Archive similarly
Similar concept applied to group messages, except that archiving and unarchiving
will apply to all group members
Re-organise user page so it is easier to find interesting info
split it into tabs
- Introduce notifications and messages tabs
- Stop couting stuff for the user page to speed up rendering
- Suppress more information when viewing your own profile
Since I18n has a DB backend now, I've introduced a helper we can use to
skip overrides in certain situations. Otherwise migration from empty
databases was broken.
Group owners are regular users that can add or remove users to a group
The Admin UX allows admins to appoint group owners
The public group UX will display group owners first and unlock UI to
add and remove members
Group owners can only be appointed on non automatic groups
Group owners may not appoint another group owner
