From e42d3437ba922945425336cc34ac8472465bb84d Mon Sep 17 00:00:00 2001 From: Andrew Hundt Date: Mon, 15 Dec 2025 19:08:31 -0500 Subject: [PATCH 1/5] fix(api): graceful handling of server unreachable errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When Happy API server is unreachable, the CLI was crashing with uncaught exceptions. Now handles connection errors gracefully and continues in offline mode. Changes: - api.ts: Add connection error handling (ECONNREFUSED, ENOTFOUND, ETIMEDOUT) - getOrCreateSession: Returns null when server unreachable - getOrCreateMachine: Returns minimal Machine object when server unreachable - Updated return types to reflect null handling - runClaude.ts, runCodex.ts: Handle null API responses with graceful exit - Show clear user message: "⚠️ Happy server unreachable - continuing in local mode" - Add comprehensive unit tests for server error scenarios This allows users to continue using Happy CLI in local mode even when the server is temporarily unavailable. --- .release-it.notes.js | 94 ++++++++++---------- src/api/api.test.ts | 186 ++++++++++++++++++++++++++++++++++++++++ src/api/api.ts | 87 +++++++++++++++---- src/claude/runClaude.ts | 9 ++ src/codex/runCodex.ts | 9 ++ 5 files changed, 322 insertions(+), 63 deletions(-) create mode 100644 src/api/api.test.ts diff --git a/.release-it.notes.js b/.release-it.notes.js index 6b942f3e..3d88c3aa 100755 --- a/.release-it.notes.js +++ b/.release-it.notes.js @@ -1,51 +1,57 @@ #!/usr/bin/env node -import { execSync } from 'child_process'; +import { execSync } from "child_process"; /** * Generate release notes using Claude Code by analyzing git commits * Usage: node scripts/generate-release-notes.js */ -const [,, fromTag, toVersion] = process.argv; +const [, , fromTag, toVersion] = process.argv; if (!fromTag || !toVersion) { - console.error('Usage: node scripts/generate-release-notes.js '); - process.exit(1); + console.error( + "Usage: node scripts/generate-release-notes.js " + ); + process.exit(1); } async function generateReleaseNotes() { + try { + // Get commit range for the release + const commitRange = + fromTag === "null" || !fromTag ?
