The VIP editor put routing and traffic observations in a dense text block,
while nested layouts in the devices grid could let text escape its row.
Separate the VIP overview from configuration and draw both live tables with
explicit cell bounds, font-aware row heights, clipping and horizontal overflow.
Measure columns before painting and keep widths stable as live values change.
The overview reuses the existing traffic sparklines for service totals and
individual listener backends, with TX/RX rates, health, RTT, open flows and
counters. Retain bounded histories by service/listener/backend identity and
release them when their resources disappear. Recreated listeners start fresh.
Use egui 0.31 Scene and Painter for a pannable, zoomable routing diagram with
Fit, clickable backend details and linked table selection. Highlight recent
counter growth separately from the backend selected for new connections;
idle bindings alone do not imply traffic, and stale activity expires. Draw
legend markers directly rather than depending on optional font glyphs.
The overview only reads saved observations; edits and deletion still require
Save. No dependencies, wire formats, IPC or persistent schemas change.
Validation on Linux through nix develop:
- cargo fmt --all -- --check
- cargo clippy --locked --workspace --all-targets -- -D warnings
- cargo test --locked --workspace --all-targets: 566 passed, 3 ignored
- cargo build --locked -p tsunagi-tray
The inherited TSUNAGI_CONTROL_SOCKET was unset for Clippy and tests.
Seven new GUI tests cover enlarged fonts, mixed online/offline rows, long
names, large counters, narrow/wide layouts, scene clicks, traffic selection,
stale samples, counter resets, listener recreation and history cleanup.
The first enlarged-font regression exposed an override-font height mismatch;
row sizing now resolves the actual selected font and the regression passes.
A disposable fixture preview rendered successfully with software OpenGL on
an isolated Xvfb display. Initial Xvfb attempts needed explicit xkbcommon and
OpenGL runtime paths in the Nix environment. The preview never contacted an
agent; its temporary source was removed. macOS, Windows, Wayland and live host
TUN traffic were not exercised by this UI change.
