Since Mithril doesn't really offer granular redraw control, typing in a text input on a modal would trigger a redraw for the whole page (including the page content behind the modal) on every keystroke. This commit allows components to be "paused" so that their vdom subtree will be retained instead of reconstructed on subsequent redraws. When a modal is opened, we pause the main page component, and when it's closed, we unpause it. This means that while a modal is visible, only the content inside of the modal will be redrawn, dramatically improving performance.
- When no discussions are visible, the query that filters posts by discussion visibility was incorrectly making all posts visible.
- Also hide user profiles altogether if discussions are not visible.
A bit of an edge-case since it shouldn't really be possible to have a discussion with zero posts anymore, but when renaming an empty discussion (or taking any action that will create an "event post"), Flarum would crash. This is due to the MergeableInterface requiring these posts to be saved after a previous post.
When renaming a discussion, an attempt is made to send a notification to the discussion's author. However, there is no check to see if the user account still exists - this can lead to a crash. While the check should technically be in the initiating code, it will probably slip through the cracks in other scenarios/extensions, so it's probably best that we safe-guard against this in the NotificationSyncer itself.
- On the front-end, correct the check to see if the discussion has no more posts
- On the back-end, run a query to count the posts instead of using the comments_count, because the comments_count does not include other deleted posts
Laravel's alpha_dash rule allows unicode letters including those with inflections, leading to issues like #832. As per discussion in #557, we are sticking with ASCII-only usernames for now.
Unfortunately we have no way to calculate the number of comment posts that are previous to the current viewing position of the discussion, without loading all of the posts which is going to be too expensive (even if we do it selectively somehow).
Also fixes a couple of miscellaneous bugs:
- Minimise the Composer when clicking the preview button in full-screen mode on desktop.
- Minimise the Composer when clicking the link to the discussion/post in the header on mobile/full-screen mode.
This will make it much easier for extension developers (and also less
error-prone) to create migrations for things like creating tables,
renaming columns and so on...
