- Add window resize listener as fallback for ResizeObserver
- Use 250ms debounce to avoid early layout reads
- Delay term.refresh() to next animation frame so renderer
can process resize before we force redraw
- Clean up window resize listener on unmount
- Add window resize listener to complement ResizeObserver
- Clear window resize timeout on cleanup
- Force term.refresh() after font size changes
- Send resize message after font size change
- Frontend: Add ResizeObserver with dimension tracking for accurate resize detection
- Frontend: Fix cleanup function to properly disconnect ResizeObserver
- Frontend: Use CSS grid for terminal wrapper layout
- Backend: Add duplicate dimension check to avoid unnecessary resizes
- Backend: Ensure stty command is sent correctly to container shell
Issues fixed:
1. Terminal container now has explicit width: 100% and height: 100%
2. Added term.refresh() after fit() to force redraw when dimensions change
3. Changed shell-body from min-height to height for definite sizing
4. Added .xterm-viewport width: 100% to ensure proper filling
This ensures the terminal properly fills the viewport and redraws
content when the window is resized.
When window resize fires, CSS layout hasn't settled yet. Adding
requestAnimationFrame ensures the browser has calculated new sizes
before xterm.js fit() reads the container dimensions. Reduced
debounce from 250ms to 100ms since rAF handles the layout timing.
The terminal page uses height: 100% but parent .shell-content didn't
have explicit height, so the terminal couldn't fill the viewport.
Changes:
- .shell-content: added height: 100%
- .shell-body: added flex: 1 to fill flex parent
- Mobile .shell-content: added height: 100%
This ensures the terminal wrapper can properly calculate and fill
the available viewport space.
The ResizeObserver detected size changes caused by the stty command
output appearing in the terminal, creating an infinite resize loop:
1. Resize detected -> fit() -> send resize to backend
2. Backend sends stty command through PTY
3. stty text appears in terminal output
4. ResizeObserver detects content height change
5. fit() calculates new rows -> send resize
6. Loop continues forever
Reverted to:
- Window resize event instead of ResizeObserver
- stty command only sent once on first resize
This means the container shell stays at the initial size and won't
dynamically resize when the browser window changes, but prevents
the infinite loop.
Window resize events fire before CSS layout settles, so FitAddon
was reading stale container dimensions. ResizeObserver fires after
the element actually changes size, ensuring fit() gets correct
dimensions. Reduced debounce from 250ms to 100ms for snappier response.
- Backend PTY starts with default 80x24 dimensions
- Previous code only sent resize during layout changes
- Now sends current terminal size immediately when WebSocket opens
- Ensures PTY is properly sized before shell starts rendering
- Simplified fit logic: just fit after open, after fonts load, and on resize
- Added console logging to debug what FitAddon calculates
- Single fitTerminal() function used everywhere
- Removed complex retry logic that wasn't working
- Wait for document.fonts.ready before fitting (ensures correct cell metrics)
- Retry fit every 100ms if rows <= 1 or cols <= 10 (layout still settling)
- Up to 30 retries (3 seconds) for layout to stabilize
- Remove redundant delayed fits, keep only header auto-hide fit at 4s
- Container-level ResizeObserver created feedback loop with fitAddon.fit()
- Removed it, kept initialization-time dimension check only
- Rely on window resize listener for viewport changes
- xterm docs require parent to have dimensions when open() is called
- Added ResizeObserver to wait for non-zero dimensions before initializing
- Added container ResizeObserver to handle resizes (header hide, keyboard)
- Fixed cleanup to properly disconnect observers and handle uninitialized ws
- Don't reconnect when server closes old connection with code 4000
- Code 4000 means new connection was established, not an error
- Prevents infinite reconnection loop between old/new connections
Refs: terminal switching between 4000 error and connected
- Measure parent dimensions and set them on container before term.open()
- Ensures FitAddon gets correct dimensions on initialization
- Prevents 1-row/1-col calculation that breaks scrolling and sizing
- Backend: Send ping every 30s from WebSocket endpoint
- Frontend: Respond to pings with pongs, detect missed pings (60s timeout)
- Update type definitions to include 'resetting' status
Refs: persistent-terminal-sessions task 6.4
TypeScript build failed because 'resetting' status was not included
in the onTerminalReady callback type definition.
Updated types in:
- TerminalComponent props
- MobileTerminalWrapper state and callback
- MobileTerminalHeader props
Replace flexbox chains with CSS Grid to give content area definite height:
- grid-template-rows: auto 1fr auto for header/content/keys
- Use 100dvh for proper mobile viewport handling
- Terminal fills content area with position: absolute
- Remove mobile-terminal-shell wrapper (redundant)
- Content area gets real height from grid, fixing FitAddon calculations
- Terminal sessions now persist across WebSocket disconnections
- Added circular output buffer (10KB) for replay on reconnect
- Added idle timeout cleanup (30 minutes)
- Added reset functionality via WebSocket message and HTTP endpoint
- Concurrent connections close old WebSocket when new one connects
- Frontend: Added reset button with confirmation dialog
- Frontend: Handle resetting status and reconnection
Refs: persistent-terminal-sessions
- Make .terminal-container position: relative with overflow: hidden
- Make xterm element absolutely positioned to fill container
- This ensures xterm.js always has concrete dimensions for fitAddon
- Remove conflicting height: 100% !important overrides
- Terminal now properly fills available space and calculates correct rows
The ResizeObserver triggered fit() which changed canvas dimensions,
triggering the observer again in an infinite loop. We already have
window resize handling and delayed fit() calls, so the observer was
redundant.
- Change .terminal-wrapper.mobile from height:100% to flex:1 for proper flex behavior
- Add explicit width/height to xterm-viewport and xterm-screen to prevent overflow
- Add delayed fit() at 4s to resize after mobile header auto-hides
- Remove min-height:100% which caused overflow issues
- Add SessionCard component with status indicators, actions, and confirmation dialogs
- Add SessionList component with grouping (active/recent) and filtering
- Refactor dashboard.tsx to use unified components
- Refactor sessions.tsx to use unified components
- Remove duplicated session rendering logic from both pages
Refs: session-list-overhaul tasks 1-4

- Let flexbox handle the layout naturally
- Add ResizeObserver to watch terminal container and trigger fit() on size changes
- Add delayed second fit() call 500ms after initialization
- Remove initial setTimeout resize in favor of ResizeObserver
- Ensure resizeObserver is cleaned up on unmount

- Terminal container now properly fills available vertical space
