From a98529868e8a2cb5e02fb75f9b442fd7da637083 Mon Sep 17 00:00:00 2001 From: Dorian Date: Fri, 13 Mar 2026 03:32:21 +0000 Subject: [PATCH] feat: fix Tor rotation to handle system Tor and hostname caching read_onion_address() now checks tor-hostnames readable cache first, clears cache before wait_for_hostname, updates it after rotation. Rotation restarts system Tor (not just archy-tor container). Created test-tor-rotation.sh with 10 automated checks (INSTALL-03).

Fixed pubkey mismatch: added `node.nostr-sign` RPC that uses the node-level Nostr key (matching `node.nostr-pubkey`), updated frontend appLauncher to use it. Added `nostr_sign_hash()` to nostr_discovery.rs. Created `scripts/test-nip07.sh` — 11/11 automated checks pass (injection, pubkey, signing, content integrity, NIP-04). Browser-based consent modal test documented as manual steps. On 192.168.1.228: (1) Open a proxied iframe app (e.g., `/app/mempool/` or any app with an HTML page), (2) In browser DevTools console, verify `window.nostr` exists, (3) Call `window.nostr.getPublicKey()` — verify it returns the node's Nostr hex pubkey (compare with `node.nostr-pubkey` RPC response), (4) Call `window.nostr.signEvent({kind: 1, content: "test", created_at: Math.floor(Date.now()/1000), tags: []})` — verify consent modal appears, approve, verify signed event returned with valid `sig` field. Document the test steps and results. **Acceptance**: NIP-07 works in at least one iframe app. Consent modal functions.

Peers update automatically. No federation disruption. +- [x] **INSTALL-03** — Test Tor rotation end-to-end on live server. Fixed: `read_onion_address()` now checks `tor-hostnames/` readable cache first (system Tor owns hidden service dirs at 0700), clears cache before waiting for new hostname after rotation, updates cache after. Fixed rotation to restart system Tor (`systemctl restart tor`) instead of only archy-tor container. Created `scripts/test-tor-rotation.sh` — 10/10 checks pass (rotation, address change, cache sync, transition period, cleanup, federation propagation). - [ ] **INSTALL-04** — Run full federation + sharing + DWN integration test. Deploy latest code to all 4 servers. Run this sequence: (1) Federate all 4 (if not already), (2) Share a file from each node (4 files total), (3) Browse peer content from each node — verify all 4 files visible, (4) Write DWN messages on each node, sync, verify replication, (5) Open Federation dashboard — verify network map shows all 4 nodes online, (6) Verify health monitor is running on all nodes (check for auto-restart of intentionally stopped container), (7) Rotate Tor address on one node, verify peers update. Script the entire flow in `scripts/test-integration-full.sh`. **Acceptance**: All 7 steps pass. Script exits 0.
