Feature/public url - #103
Conversation
Introduce the Tauri share module: API client, loopback OAuth + keychain session, relay WebSocket agent with localhost proxy, and IPC commands for CRUD, tickets, and login cancel.
Add the React store/IPC layer and Public URLs panel with Zync sign-in, quota UX, OAuth cancel/retry, avatar display, and Beta badge helpers.
Expose Public URLs (Beta) from the sidebar, profile menu, command palette, and workspace tabs, preferring the Zync account avatar over Drive Sync when signed in.

📝 WalkthroughWalkthroughAdds the Public URLs beta feature. The change includes Zync OAuth, share creation and lifecycle controls, relay agents, local HTTP/WebSocket/TCP proxying, Tauri commands, client state, and Public URLs navigation and panels. It also changes port-forwarding views and remote listen-port handling. ChangesPublic URLs feature

Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds public URL sharing that sends account credentials, relay credentials, and shared local-service traffic to build-configured API and relay endpoints, including HTTP/WS endpoints without enforced trusted-host or secure-transport restrictions. A bad or compromised endpoint could expose credentials and shared data, so merging should wait until production endpoint validation and secure transport are enforced.

Inline comments:
In `@src-tauri/src/share/agent.rs`:
- Around line 530-536: Update the send path in the reader loop around streams
and data_sender so a full per-stream channel does not await indefinitely: use a
bounded/non-blocking send operation, and cancel or remove only the affected
stream when delivery cannot proceed. Keep processing subsequent session
messages, including pings, and preserve normal delivery for streams with
available capacity.
In `@src-tauri/src/share/proxy.rs`:
- Around line 413-418: Update read_http_headers so each stream.read operation is
wrapped with tokio::time::timeout using DIAL_TIMEOUT, propagating the read error
and returning an error when the timeout expires; preserve the existing handling
for EOF and successful header accumulation.
- Around line 257-258: Update proxy_websocket to merge readers.req_rx with
readers.extra_rx and process messages from both receivers, rather than dropping
req_rx. Preserve forwarding of TYPE_DATA payloads sent before the first
TYPE_CLOSE, and handle any resulting send failures consistently with the
existing receiver flow.
In `@src/components/share/PublicUrlsPanel.tsx`:
- Line 434: Update the Button onClick handler in PublicUrlsPanel to attach a
rejection handler to the promise returned by startSharing instead of discarding
it with void. Reuse the existing parsed-error toast handling so
share_agent_start failures are shown to the user without producing an unhandled
promise rejection.
In `@src/features/share/ipc.ts`:
- Around line 30-31: Use the account-specific quota message throughout the
sharing flow: in src/features/share/ipc.ts lines 30-31, preserve the backend
quota message or format the fallback with the current quota; in
src/components/share/PublicUrlsPanel.tsx lines 383-386 and 449-450, replace the
fixed beta message with quotaFullMessage(quotaUsed, quotaMax) using the
entitlement-specific values.
In `@src/features/share/useShareStore.ts`:
- Around line 171-177: Update the refresh method in useShareStore so that after
recording parseShareError(error).message in state, it rethrows the original
failure instead of resolving successfully. Ensure callers of create, stop,
start, delete, and agent start observe failed post-mutation refreshes and do not
report completion while shares are stale.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Use non-blocking stream sends, time out WS header reads, merge early WS body data, surface start-sharing failures, prefer server quota copy, and fail mutations when post-refresh status fails.
Replace dense cards with a compact host-grouped table, optional matching tiles, search and type/status filters, persisted view, host icons, and Copy/Open on the row.
When tcpip-forward is rejected, probe nearby remote ports and reuse the local port-conflict picker if one bind succeeds and is released. Policy rejects still surface the original error.
Update TUNNELS.md surfaces/file map and CHANGELOG Unreleased for the compact list/grid and remote -R conflict flow.

Inline comments:
In `@docs/TUNNELS.md`:
- Line 166: Update the documentation sentence describing the all-probes-failed
case in find_next_available_remote_port to remove the unsupported sshd policy
attribution, stating only that the original rejection is retained.
In `@src-tauri/src/share/proxy.rs`:
- Line 266: Update the forwarding logic around the tokio::select! in the stream
proxy to fully drain req_rx before consuming any data from extra_rx, preserving
the original byte order across TYPE_CLOSE. Add a regression test that buffers
data on both channels and verifies writes reach the upstream stream in channel
order.
In `@src-tauri/src/tunnels/manager.rs`:
- Around line 604-620: Update the probe cleanup flow around cancel_tcpip_forward
and remote_probe_suggestion so a failed cancellation preserves ownership of the
active candidate port for later stop_tunnel cleanup, or closes the SSH session
when ownership cannot be retained. Ensure the failure path does not discard
candidate, and add an integration test covering a successful tcpip_forward
followed by failed cancel_tcpip_forward.
In `@src/components/tunnel/TunnelManager.tsx`:
- Around line 265-268: Update the onCopy handler in
src/components/tunnel/TunnelManager.tsx at lines 265-268 to be async, await
navigator.clipboard.writeText, show the success toast only after it resolves,
and show an error toast in catch. Apply the same change to copyHandlers.onCopy
in src/components/tunnel/GlobalTunnelList.tsx at lines 487-490.
In `@src/components/tunnel/TunnelRow.tsx`:
- Around line 199-202: Update the overflow menu trigger’s class list in
src/components/tunnel/TunnelRow.tsx:199-202 to reveal it on keyboard focus via
focus-visible opacity. Also update the controls container in
src/components/tunnel/GlobalTunnelList.tsx:537 to reveal the Start all and Stop
all buttons when focus is within it via focus-within opacity.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Write req_rx fully before extra_rx so TYPE_DATA before the first TYPE_CLOSE is not interleaved with later frames.
Keep remote probe binds that fail to cancel so disconnect can clean them up. Await clipboard writes, reveal overflow and Start/Stop all on keyboard focus, and tone down remote-probe docs wording.
Cut Unreleased into 2.27.0 with commit links for Public URLs Beta, Port Forwarding redesign, and related fixes.
Add Public URLs as a separate OAuth/agent/relay surface from Drive Sync and SSH tunnels, plus operator notes for localhost-only proxy and optional survey/feedback.
Stop hardcoding production Public URLs API/relay hosts. Release builds require ZYNC_SHARE_API_BASE and ZYNC_SHARE_RELAY_URL. Debug uses local zync-share loopback.

Inline comments:
In `@docs/SECURITY.md`:
- Line 41: Update the feature description beginning “Public URLs is” to use
grammatically correct wording, either “Public URLs are” or “The Public URLs
feature is,” while preserving the rest of the statement.
- Line 10: Update the security statement for the Public URLs share agent to
clarify that Zync does not automatically send SSH sessions, vault secrets, or
terminal content to Zync-operated hosts, while acknowledging that HTTP,
WebSocket, and TCP data served by the user-selected shared loopback port is
proxied through the relay.
In `@src-tauri/src/share/config.rs`:
- Around line 15-16: Update the share endpoint configuration around baked_url,
api_base, and relay_url to reject http:// production API and relay URLs in
release builds, while preserving permitted HTTPS endpoints and existing debug
behavior. Ensure run_session cannot derive an insecure ws:// relay for
authenticated tickets and bearer-authenticated API requests cannot use an
insecure base URL.
In `@src-tauri/src/tunnels/manager.rs`:
- Line 532: Update the orphan cleanup flow around remote_forwards and
cancel_tcpip_forward so a failed cancellation does not remove the entry; retain
it for bounded retry or session shutdown, and remove it only after successful
cancellation. Add a regression test covering failed orphan cancellation and
verifying the entry remains available for cleanup.
In `@src/components/tunnel/GlobalTunnelList.tsx`:
- Line 539: Prevent keyboard events from the Start all/Stop all action container
from reaching the host header’s onKeyDown handler, so activating either button
with Enter or Space does not call toggleHost. Update the action container near
the group action buttons in GlobalTunnelList and preserve normal button
activation behavior.
