Threadsafety
Since we use the same redis connection in multiple threads, a rogue
transaction in another thread can trample the connection state
(watched keys) that we need to acquire and release the lock properly.
This is fixed by preventing other threads from using the connection
when we are performing these actions.
Off-by-one error
A distributed mutex is now consistently determined to be expired if
the current time is strictly greater than the expire time.
Unwatch before transaction
Since the redis connection is used by so much of the code, it is
difficult to ensure that any watched keys have been cleared. In order
to defend against this rogue connection state, an unwatch has been
added before locking and unlocking.
Logging
Hopefully this log message is more clear.
Clicking fast on the "top", "unread", or "latest" button when browsing a parent category page with subcategories and the setting `Show subcategory list above topics in this category` enabled would cause an exception:
```
Uncaught Error: Nothing handled the action 'triggerRefresh'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.
```
I introduced DemonBase because I had got some conflict between `demon/base.rb` and `jobs/base.rb`, however, to not rename base class, it is possible to use regex on absolute path in Zeitwerk custom inflector.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Adds 2 factor authentication method via second factor security keys over [web authn](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API).
Allows a user to authenticate a second factor on login, login-via-email, admin-login, and change password routes. Adds registration area within existing user second factor preferences to register multiple security keys. Supports both external (yubikey) and built-in (macOS/android fingerprint readers).
Advanced trigger is currently broken on:
ca
es
et
fr
he
it
pt_BR
And that is because the translation levels for the plugin are kinda low, so I would guess it's broken for half the languages.
Since we have only two tracks for a while now, a quick fix to me is inverting the selectors.
This patch works because the advanced key is "larger" than the new user one.
Currently, the topic is only validated for censored words and should be validated for blocked words as well.
Blocked word validation is now used by both Post and Topic. To avoid code duplication, I extracted blocked words validation code into separate Validator, and use it in both places.
The only downside is that even if the topic contains blocked words validation message is saying "Your post contains a word that's not allowed: tomato" but I think this is descriptive enough.
Some site settings (e.g. `unicode_username_character_whitelist`) depend on the default locale, so we need to reset the watched settings when the locale changes.
Keeps element 1em away from the right edge of screen
Takes DiscourseHub app nav position into account on iPad
Uses outerHeight to calculate element height including padding/borders
This updates rubyzip library so that callers can trust entries when
extracting files avoiding situations where a rogues zip imported by a rogue
admin could cause a disk space issue.
This corrects an XSS in ?pp=help.
Also removes the jQuery dependency from rack-mini-profiler and restricts
memory sensitive profiling methods development only.
Per new lifecycle https://developers.google.com/web/updates/2018/07/page-lifecycle-api
On Android and latest Chrome when an app transitions from "frozen" to
active the new "resume" event fires with no accompanying "visibilitychange"
event.
This means that often background tabs may be stuck thinking that discourse
has no focus when, indeed, it has.
This leads to cases where no posts are marked read anymore.
This applies to iPhones running iOS 13+.
Previous technique remains in place for iOS 12 and below.
Note that this does not apply to iPads on iOS 13 due to Apple no longer
identifying iPads in the user agent string.
The current manifest validation in Chrome requires at least one
non-maskable icon to make it installable.
This commit adds the maskable entry as another entry, following up
on changes added in 3e590b8
Because:
- Chrome 78 and Firefox Fenix have support for it
- The icons will look better by using all the availiable space
- Admins can control the icon and add appropriate padding since we have a
dedicated asset for the manifest logo. Read more about it on
https://css-tricks.com/maskable-icons-android-adaptive-icons-for-your-pwa/
This commit:
- Adds a new key under the icons array in the webmanifest, named purpose
with maskable value.
Previously, calculating thresholds for reviewables was done based on the
50th and 85th percentile across all reviewables. However, many forum
owners provided feedback that these thresholds were too easy to hit, in
particular when it came to auto hiding content.
The calculation has been adjusted to base the priorities on reviewables
that have a minimum of 2 scores (flags). This should push the amount of
flags required to hide something higher then before.
