ghostty-web 0.4.0 hands rows that scroll into view out of recycled WASM
page memory without clearing them, so after a tab or project switch the
new emulator showed the previous terminal's text (upstream #138). The fix
landed only in prereleases, so pin 0.4.0-next.20 and carry the local
block-glyph rendering patch over to the new dist file.
Verified in a production build: creating an emulator after disposing a
full one no longer exposes its rows, and switching between two projects
with live output in each keeps every terminal's content to itself.
Opening the terminal panel sometimes showed stray fragments on the prompt
row: zsh's end-of-line mark and pieces of the prompt path. The shell had
laid its output out for one PTY width, but the client replayed that
history into an emulator of another width (an early size estimate, a
remount, or a renderer rebuild after fonts loaded). ghostty-web's reflow
then left fragments the shell's SIGWINCH redraw never clears.
The server now reports the PTY cols/rows in every snapshot, the transport
carries them through projections and accepted resizes, and the viewport
replays a sized snapshot chunk at that size before returning to the
fitted size. The container-based size estimate only seeds newly spawned
shells and is no longer sent to a running PTY.
Tests cover the sized replay, the store chunk size, the transport
projection, and the server snapshot; verified in a production build by
reloading with the panel open and switching tabs at a changed width.
Replace the legacy terminal flow with a shared authenticated WebSocket
runtime used across web, desktop, relay, and mobile surfaces.
- introduce the v3 terminal protocol with scoped attachments, snapshots,
ordered output, bounded replay history, reconnects, and explicit lifecycle
- harden PTY creation, restart, resize, close, force-kill, idle cleanup,
shell selection, login mode, environment sanitization, and appearance sync
- add runtime-aware terminal APIs with relay authentication and Electron parity
- add a fullscreen mobile terminal workspace with touch scrolling,
long-press selection, safe-area controls, quick keys, and Ctrl/Alt input
- add terminal selection attachments, preview detection, project actions,
shell settings, and localized UI
- harden Ghostty rendering, resize recovery, Unicode handling, block
characters, line height, and stale-row behavior
- remove the obsolete terminal SSE path and update reverse-proxy guidance
- expand terminal runtime, transport, input, selection, and store coverage
- avoid duplicate web builds when preparing mobile assets in root CI builds
- Replace virtua with @tanstack/react-virtual for chat history on all
surfaces: bottom anchoring (anchorTo: end), key-stable prepend
preservation, and native iOS touch/momentum deferral live in the core
- Patch virtual-core to clamp the render range to real scroll bounds
during transient adjustments
- Rows render in normal flow inside a translated wrapper so sticky user
headers keep working; measurement snapshots cached per session
- Pre-write container height in scrollToFn so the browser cannot clamp
anchor corrections to the stale height; hold the prepend anchor for up
to 180 frames on mobile while fresh rows settle (cancelled by user
input; desktop relies on core anchoring alone)
- Adaptive row-size estimate from per-session measured averages; disable
reveal fade-in for virtualized history rows
- Mobile loads older history only through an explicit localized top
button: no scroll-position trigger and no post-mount background
prepend, so every insert happens from a resting state; a quiet-window
hold defers any stray prepend commit while a touch gesture is active
- Desktop/VS Code keep the seamless scroll-up trigger and progressive
background prepend
