xarmian c50f0585ad fix(collab): WebSocket dials get their own per-user bucket and a per-user socket cap, and the editor jitters its reconnects (BUG-1308) (#1499)
* fix(collab): WebSocket dials get their own per-user bucket and a per-user socket cap; the web provider jitters its reconnects (BUG-1308)

A collab dial drew on the general per-user API bucket (burst 60), so 100
dials from one user got 60 through, and a user's own dials and REST
calls refused each other. Dials now draw on a CollabDial bucket (5/s,
burst 50), and how many sockets a principal may hold is bounded
separately by PAD_COLLAB_MAX_PER_USER (default 50), refused with 429
collab_limit_exceeded and Retry-After. Both defaults are sized from the
reconnect-storm measurement on BUG-1308's trail (checkpoint 2).

A browser cannot read a refused handshake's status, so the provider's
backoff is what spaces a refused herd out: each step is now jittered to
between half and all of itself.

* docs(collab): PAD_COLLAB_MAX_PER_USER and the collab dial bucket, in the deployment docs, samples and load-test usage (BUG-1308)

* fix(collab): only a WebSocket upgrade is a dial; per-user cap pinned within one workspace; dial-bucket keying stated correctly (BUG-1308, codex round 1)

Claude-Session: https://claude.ai/code/session_01RYiqbqXmxQMoKHsGm8B77N

* docs(collab): a PAD_COLLAB_MAX_PER_USER below 1 means unlimited, as the SSE knobs do (BUG-1308, codex round 2)

* docs(collab): the struct field agrees, 0 or less is unlimited (BUG-1308, codex round 3)

Pad Web UI

SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.

Development

npm install
npm run dev          # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build        # Production build to build/
npm run check        # Type checking with svelte-check

When developing, run the Go backend separately with make dev from the project root.

Building for Production

Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.

Stack

  • Svelte 5 with runes ($state, $derived, $effect)
  • SvelteKit 2 with adapter-static (SPA mode)
  • Tiptap block editor with markdown round-trip
  • svelte-dnd-action for drag-and-drop in board/list views
  • SSE for real-time updates
  • TypeScript throughout
