- Reintroduce cancellable scroll top on page change
- IndexPage: rely on browser to retain scroll position on page reload
- Remove obsolete browser hack
- Fix broken selector
- When on mobile, only retain scroll for IndexPage if we're coming from a discussion
- Move app.cache.scrollTop save into `onbeforeremove` so we make sure to do it before DOM is detached
The default first post number is '1', so we scroll to that if we're calling `m.route.set` without a `near` parameter, as that means we're scrolling to the top.
This was present in beta 13's implementation, but accidentially omitted in 988b6c9.
We also remove unnecessary typecasting for simpler logic and increased consistency with beta 13.
The current implementation for checking whether we are on a discussion page, and going to a discussion page, checks the route we are going to. This is problematic, because the route resolver represents the route being considered, not the route we are currently on. So, if we are currently using a DiscussionPageResolver, we must be going to a route handled by DiscussionPage. Instead, we need to check the route that we are currently on, which is done via `app.current.matches(DiscussionPage)`.
- mapRoutes: don't wrap components in resolvers if they are already resolvers
- Extract defaultResolver into its own class
- Allow either route resolver instances, or components with an optional resolverClass which should accept the component and route name in its constructor.
- Introduce a resolver for DiscussionPage, so that routing from one post to another on the same discussion triggers a scroll instead of rerendering
- Add an index to reply placeholder so we can scroll to it directly when replying.
- Stop pretending that the currently broken `bottom` scroll functionality works, and explicitly call it `reply` scrolling to be clearer
- Directly get target from state
- Explicitly scroll to placeholder on reply
- Clean up scrollToItem code a bit
- Account for edge case where index is undefined when scrolling to post

Essentially, whenever a route is loaded, we add a key to that component. If the key changes, the page completely rerenders. Switching between different routes handled by the same key triggers those rerenders.
- If the fadeIn animation is specified on the PostStream class itself, any time we add/remove another animation, it will redo fadeIn. To avoid this, we move fadeIn into it's own css class, which is applied, and then immediately removed after the animation is completed to ensure it only runs once.
- The "fix" for flashItem was actually broken, as it resulted in 'flash' never being removed, so we never went back to .PostStream's fadeIn. We adjust flashItem to ensure that '.flash' is removed. We also remove 'fadeIn' in case it hasn't yet been removed in oncreate.
Make header and navigation components redraw after page components. Page components manipulate the header (state), but the header redraws before the page on route change. By changing the mount order, we change also the redraw order.
If the error isn't a 409, we'll want to re-throw the error so it'll be handled by the default system (showing an alert).
For simplicity, we can also move 409-handling logic out of setTimeout.
Finally, we adjust the timeout to 300 milliseconds to match the modal transition animation length.
* Revert "Fix header contents moving when opening modal (#2131)"
* Fix header contents moving when modal opened/closed.
Conditionally apply the navbar-fixed-top class only when needed, so that we can take advantage of it without always having the navbar in position:fixed, as was done in the previous solution. That resulted in a clash with custom headers.
* Show header on refresh of scrolled page
Due to some magic in Mithril 0.1's context:retain flag, some DOM elements were cached across page reloads. Since that has been eliminated, if we refresh the page and we are scrolled down, the "affix" class which makes the header fixed (and as a result, visible) isn't applied until the first scroll. We fix this by running ScrollListener.update() immediately to set initial navbar state.
When on a discussion page, the URL changing doesn't always mean we've moved to a different page. In our custom rerender logic, we only want to call `this.onNewRoute()` if the page has actually changed.
After we scroll to a post, we redraw to render post content. We then update the scrubber again so its height is accurate. This commit moves that update to AFTER our adjustment of scroll position, so that scrubber height is based on actual post heights. This fixes some subtle scrubber glitches.
Let's stay consistent with previous behavior, and run these on "internal route change" (same component handles different route) as well as on initial render of a page component.
Currently, the controls are on a new line due to the container div. We want to wrap ALL children of the alert, including the controls, in the container div.
We need to split it into a separate class so that we can add modify the alert vnode AFTER the alert component's `view` logic has been applied.
During the frontend rewrite, we introduced mithril patches for a `route` attr, and for `m.stream`. Later, we decided not to go that route, but not to remove the patches yet to avoid breaking extensions while we were finalizing the replacements. We can now remove these.
Other BC layers are for things from before beta 14, so those remain in place.
- Use Mithril.Attributes as base for ComponentAttrs, remove =any from class signature for Component
- Convert Alert to TypeScript, introduce AlertAttrs interface
- Convert AlertManagerState to TypeScript, add overload signatures for `show`, introduce AlertState interface for stored Alerts.
- Set ComponentAttrs as default T for Component
- Make attrs in AlertAttrs optional
- Add AlertIdentifier interface, simplify show type signature
- Remove mithril patch shim, as all patches onto m are now deprecated
- Use Mithril.Static for shim
- Ensure that the discussion list is cleared before it is updated with fetched results
- Rename `clear` to `deferClear`, improve documentation to make its purpose clearer.
- Call onNewRoute when page changed with same component in DiscussionPage and UserPage
- Make app.previous and app.current changed in onNewRoute, not in oninit. This way, when the route is changed, but still handled by the same component, a new PageState object will still be created.
While more pleasant from an FSM standpoint, comparing the current targetPost to the previous one does not work if goToNumber is called twice in a row for the same post. For instance, if a user clicks the mentions link to a post twice, the post stream breaks.
In some cases, such as if we've stickied a post, an event post
may have been added / removed.This means that `this.visibleEnd`
and`this.count()` will be out of sync by 1 post, but we are still
"viewing the end" of the post stream, so we should still reload
all posts up until the last one.
