New Logs section on the server detail page — tabbed viewer with
auto-refresh every 5s (toggleable), sticky-to-bottom scrolling, and a
manual refresh button. Two whitelisted files per server:
/root/zombies/t5/<name>/logs/console.log
/root/zombies/t5/<name>/logs/games_sp.log
Backend:
- src/lib/server/fleet/logs.ts — safe path resolution + tailLog()
that reads only the last 256 KB of the file, splits on newlines,
drops the (potentially partial) first line if we didn't start at
byte 0, and returns the last N lines with size + mtime + truncated.
Two path-traversal guards: server directory must be a real
subdirectory of SERVERS_ROOT, and the target must resolve inside
it.
- GET /api/servers/[name]/logs/[file]?lines=200 — whitelisted keys
only (console, games_sp), 400 on unknown keys, ok:true+missing:
true when the log file hasn't been written yet.
Frontend:
- LogPanel.svelte with tabs, auto-refresh checkbox, size/mtime meta,
and a <pre> body that snaps to bottom on refresh unless the user
has scrolled up.
- 7 unit tests covering path safety (including .. traversal) and
tail behavior (missing file → null, small file, oversized file
→ truncated, trailing newline handling).
