Two independent Svelte 5 effect-loop bugs that triggered the
same 'effect_update_depth_exceeded' guard:
1. PostCard.svelte: the embed-quote-fetch $effect and the
likedBox $effect.pre read a state variable (quotedLoading /
likedBox) and then synchronously wrote to it in the same
effect run. Svelte 5's effect tracker schedules
possible_effect_self_invalidation on the touched state, the
effect re-fires immediately, and the cycle trips the
'flush_count > 1000' guard. With ~30 PostCards mounting on
login the per-card loop compounds into the depth exceeded
error. Wrap the read+write blocks in untrack() so the
hydration flags don't contribute to the effect's dep set;
the outer 'post.embed.uri / post.did / post.rkey' reads
remain tracked so navigation between cards still triggers a
fresh hydrate.
2. App.svelte: the four $effect blocks (home-refresh,
home-poll, profile-refresh, search-debounce) lived and died
together. Even after splitting, Svelte 5 still flagged the
call chain into refreshTimeline / refreshProfile because
their sync prelude writes 'timelineLoading = true' /
'profileLoading = true' while the effect already tracks the
same downstream state via the proxy. Drive everything
imperatively through a single setView(v) function and move
the 5s poll into the session.subscribe callback, which fires
only on actual login/logout transitions. setView is the
single point that flips view AND triggers the right refresh
per destination — NavRail on_select, LoginScreen onLogin,
handleLogout, the 'back to timeline' button, and the tray
navigate-event bridge all route through it now.
Also: NavRail and StatusBar self-style their grid-area in
their own component styles ('grid-area: rail' / 'status') so
App.svelte doesn't need the fragile '$state.s-XXX > nav.rail'
cross-component selector that Svelte 5 was failing to match
in the Tauri webview, leaving rail buttons invisible to clicks.
Svelte 5's <style> block scopes selectors to elements with the
component's hash class (e.g. body.svelte-1n46o8q). The actual
<html>, <body>, and <div id="app"> are OUTSIDE the component
(no svelte class), so the rules targeting them silently don't
match anything. The previous CSS-layout fix at 2558113 added
"html, body { display: flex; ... }" but it was scoped — body
was not a flex container, the shell collapsed to its content
height, and the viewport went blank (user reported 'die app
zeigt nur eine weisse seite').
Wrap the body/HTML rules in :global() so they target the
actual document elements. Add :global(#app) too so the
Svelte root mounts into a flex column. After the fix the
bundled CSS contains:
body { display: flex; flex-direction: column; height: 100% }
#app { display: flex; flex-direction: column; flex: 1 1 auto; min-height: 0 }
and the shell finally fills the viewport.
All other CSS in the file targets elements inside the
component template (login-wrap, shell, main, etc.) and was
already correctly auto-scoped by Svelte.
The CSS-Layout was broken: `html, body, #app` had
`height: 100%; overflow: hidden` but NO `display: flex`.
The shell has `flex: 1` which only works when the parent is
a flex container, so the shell collapsed to its content
height and `.main { overflow: auto }` had no scroll
target. The user reported 'kann nicht scrollen nix anklicken
etc.' even after the previous click-bug fixes — clicks
were registered but the visible area was just the natural
content height of the shell, so there was nothing to scroll
and a large area of the viewport was blank.
Fix: make html/body a flex column (`display: flex;
flex-direction: column; height: 100%`) so the shell's
`flex: 1` actually takes the full viewport, and let
the inner shell's grid + main's overflow:auto work as
designed. Also added `#app` as a flex child for the
case where body height comes from the tauri webview's
document element instead of the html element.
This is a structural CSS fix — no Svelte or component
changes. The dev-server / Vite / NavRail issues from
previous commits are independent and remain fixed.
The `bind:current={view}` pattern in NavRail did not propagate
clicks to the parent's $state. Svelte 5's $bindable on this
runtime is flakey and on this particular build (Tauri 2.11 +
svelte 5.x) the setter was never invoked when a button was
clicked, so the view state stayed 'home' no matter which rail
button the user pressed. The user reported 'search tut sich nix
genau auch bei compose etc.'
Replace with explicit callback prop:
let { view = 'home', on_select } = $props();
onclick={() => on_select?.(item.id)}
The parent then mutates its own `view` rune directly via the
arrow function — Svelte tracks this unconditionally regardless of
runtime-specific bindable semantics.
Includes a vitest regression test that mounts a real Svelte
component harness (jsdom) and asserts that click events on each
rail button flip the parent's `view` and update the .active
class — so any future regression is caught in CI rather than at
the Tauri app window.
The profile view now has two clipboard actions:
* 'copy did' — copies the bare DID to the system clipboard
* 'copy at-uri' — copies 'at://<did>/app.twi.post' as a shareable link
Both surface a toast confirmation via the existing
maarcadetweet:notification event, so the user gets a small
'copied: ...' toast for confirmation. Right-click on a toast
still dismisses without action.
The copyToClipboard helper is in App.svelte (not pushed to
client.ts) because it only uses the browser navigator API.
OS notification body already arrived as a 'maarcadetweet:notification'
DOM event (Phase 7b). The toast pill that surfaces the body is now
clickable: left-click navigates to the URL the notification was
about (at://<did>/<col>/<rkey> opens the thread, unknown URL
falls back to the home view); right-click dismisses without
navigating. tauri-plugin-notification v2.x does not expose a
reliable OS-level notification-click callback (it only shows the
notification), so the two-step pattern (OS click focuses the app
+ in-app toast click navigates) is the standard workaround.
lastNotificationUrl is now $state so the toast title updates
when a new notification arrives.
The previous 'custom' title bar used tauri.conf.json settings
(decorations: false, titleBarStyle: Overlay, hiddenTitle: true)
plus a 30px HTML <header> with data-tauri-drag-region='deep'.
Two problems made the app unusable:
1. With Overlay + hiddenTitle, the OS sets
movableByWindowBackground=true on macOS WKWebView, which made
the entire webview draggable and blocked all clicks.
2. Tauri 2's WKWebView integration has a known issue
(tao#N) where the drag.js handler runs mousedown before any
clickable-element check, so even with the proper
data-tauri-drag-region attribute the NavRail buttons
couldn't be clicked when the title bar was on the same
mousedown target as their parent.
Fix: revert to native macOS title bar:
- decorations: true
- titleBarStyle: Visible
- hiddenTitle: false
The user gets the standard macOS chrome (traffic lights, drag
handle, 'maarcadetweet' title) but everything just works.
Custom title-bar work deferred until Tauri 3.0 (which fixes the
WKWebView + movableByWindowBackground interaction).
Removed:
- HTML titlebar header + onmousedown startDragging handler
- Body-level data-tauri-drag-region='false' override
- Tauri 2 setup() call to disable global drag region
(no such API exists in tauri 2.11.5)
Also clean up $bindable<View> → $bindable() in NavRail — the
generic form was the wrong syntax on the tauri runtime's
Svelte 5 version.
All 240 tests still pass (231 Rust + 9 vitest).
