From 5c7a6d425ff131966a7fc2d9b6fbb84318a5b6cf Mon Sep 17 00:00:00 2001 From: Ian Clarke Date: Sat, 2 Aug 2025 10:35:22 -0500 Subject: [PATCH 01/13] test: add failing test for UpdateNoChange client notification bug MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This test demonstrates that when an UPDATE operation results in no state change (UpdateNoChange), the client never receives a response and times out. The test: 1. Puts a contract with initial state 2. Updates with the exact same state (triggering UpdateNoChange) 3. Expects to receive an UpdateResponse but currently times out This test will fail until issue #1732 is fixed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- GATEWAY_FIX_PROPOSAL.md | 47 ++++++ crates/core/src/client_events/websocket.rs | 141 +++++++++++++++++- crates/core/src/node/mod.rs | 54 ++++++- crates/core/src/operations/update.rs | 17 +++ crates/core/tests/operations.rs | 159 +++++++++++++++++++++ regression_report_20250730_195608.md | 15 ++ 6 files changed, 428 insertions(+), 5 deletions(-) create mode 100644 GATEWAY_FIX_PROPOSAL.md create mode 100644 regression_report_20250730_195608.md diff --git a/GATEWAY_FIX_PROPOSAL.md b/GATEWAY_FIX_PROPOSAL.md new file mode 100644 index 000000000..f8554f624 --- /dev/null +++ b/GATEWAY_FIX_PROPOSAL.md @@ -0,0 +1,47 @@ +# Gateway Connection Fix Proposal + +## Problem Statement + +Peers connecting through gateways fail because: +1.

However, the test is timing out during execution, which suggests either: 1. The test setup is taking too long to establish connections 2. The bug is more severe and causing complete hangs 3. The test environment has performance issues Further investigation needed to determine why the test times out. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.local.md | 56 ++++++++++++++++++ PRE_COMMIT_HOOK_GUIDE.md | 68 ++++++++++++++++++++++ crates/core/src/client_events/websocket.rs | 32 +++++----- crates/core/src/node/mod.rs | 7 ++- 4 files changed, 148 insertions(+), 15 deletions(-) create mode 100644 CLAUDE.local.md create mode 100644 PRE_COMMIT_HOOK_GUIDE.md diff --git a/CLAUDE.local.md b/CLAUDE.local.md new file mode 100644 index 000000000..bf361e0ac --- /dev/null +++ b/CLAUDE.local.md @@ -0,0 +1,56 @@ +# Claude Code Development Guidelines + +This document contains important guidelines for Claude Code when working on the Freenet project. + +## TODO-MUST-FIX Pattern + +To prevent committing broken or incomplete code, we use a special comment pattern that blocks commits: + +### Usage + +When you need to temporarily disable a test or leave code in an incomplete state, use the `TODO-MUST-FIX` comment: + +```rust +// TODO-MUST-FIX: This test hangs during node startup and needs investigation +// The test attempts to start a gateway and peer but appears to deadlock +// during the node initialization phase.
