We're seeing unhandled errors in production when web push notifications are failing with an SSL error. This is happening for a few users, but generating a large amount of log noise due to the sheer number of notifications.
This adds handling of SSL errors in two places:
1. In FinalDestination::HTTP, this is handled the same as a timeout error, and gives a chance to recover.
2. In PushNotificationPusher. This will cause the notification to retry a number of times, and if it keeps failing, disable push notifications for the user. (Existing behaviour.)
I wanted to wrap the SSL error in e.g. WebPush::RequestError, but the gem doesn't have request error handling, so didn't want to have the freedom patch diverge from the gem as well. Instead just propagating the raw SSL error.
Due to some changes we started notifying via push notifications on other
families of notifications. There are a total of about 30 or so possible
notification you could get, some can be pushed.
This fallback means that if for any reason we are unable to find an icon
for a push notification we just fallback to the Discourse logo.
Also go with a simple reply icon for watching first post.
Note, that in production `image_url` can return an exception if an image is
missing. This is not the case in test / development.
Previously we would retry push notifications indefinitely for all errors
except for ExpiredSubscription
Under certain conditions other persistent errors may arise such as a persistent
rate limit.
If we track more than 3 errors in a period of time longer than a day we will
delete the subscription
Also performs a bit of internal cleanup to ensure protected methods really
are private.
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.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
The webpush gem by default sets the expiration date of the JWT token to exactly 24 hours in the future. That's not really needed because the token isn't reused. And it might cause UnauthorizedRegistration if the server's clock isn't 100% correct, because the maximum allowed value is 24 hours.
* Feature: Push notifications for Android
Notification config for desktop and mobile are merged.
Desktop notifications stay as they are for desktop views.
If mobile mode, push notifications are enabled.
Added push notification subscriptions in their own table, rather than through
custom fields.
Notification banner prompts appear for both mobile and desktop when enabled.
