fix(wizard): PG test via net.connect (drop psql subprocess) - #56

Conversation
PR #47, #53, #55 all tried to fix the PG test hang by tweaking how psql.exe is launched (DB target, stderr surfacing, stdin EOF, timeout bump). None worked — the real-user install at 2026-04-27 still showed the same `[signal=SIGTERM, killed=true (timeout?)]` after the 15s timeout. Verified: PR #55's stdin.end() + 15s timeout IS in the deployed asar (npx asar extract → grep). psql.exe still hangs in Electron context. The exact mechanism (Job Object? AppContainer? GUI-stdio?) remains unidentified, but the workaround chain is exhausted. New approach: skip psql entirely. Use Node's net.connect to verify the PG port is open at host:port. That covers the most common operator mistakes at this step (wrong port, PG not running, firewall blocking). Auth + DB existence checks are deferred to Step 6 (db_init), which spawns winserverrag-dbinit.exe — that uses psycopg + libpq directly, no psql subprocess, and works fine. Implementation: - wizard-ipc.js testPgConnection: net.Socket().connect(port, host), 5s timeout, force "localhost" → "127.0.0.1" (avoid IPv6/IPv4 mismatch). - Returns elapsed ms + a UI note explaining the test scope. - Removes ~80 lines of psql-launching machinery + diagnostic plumbing. - wizard.js step 2: button label "(psql)" → "(TCP)" + show the note. What we lose: - Auth verification at this step (deferred to Step 6, which errors loudly on bad password) What we gain: - 100% reliable test, no Electron subprocess weirdness - 5x faster (~50ms vs >5s timeout when psql hangs) - Works even when PostgreSQL client tools aren't on disk yet (server-only install) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…v fallback Three improvements to the Setup Wizard so the PG step actually validates authentication and the dev-mode loop works end-to-end: - Replace net.connect TCP-only check (PR #56) with pg.Client (npm 'pg'). Full wire-protocol handshake (TCP + StartupMessage + SCRAM-SHA-256 + SELECT 1). The earlier TCP test passed even with empty password — SCRAM completes the handshake before reporting success. Failure path maps SQLSTATE → English fixed-text (28P01 → "Password authentication failed for user") so cp932 mojibake from a JP-locale PG server stops reaching the user. - Step 2 PG password field gets a 👁 reveal toggle and live char counter. Real-user feedback: typed 13 chars when target was 12 — masked field hides the typo. Toggle + counter let the operator verify before clicking test. Counter updates on input event. - desktop/wizard-ipc.js gains resolveDaemonHelper() that falls back to <repo>\.venv\Scripts\python.exe -m src.<module> when the bundled .exe doesn't exist. Lets `npm start` drive the wizard end-to-end without a full PyInstaller build, including Step 6 db_init. - go() clears setStatus("") on step transition — without this, "接続 OK" from Step 2 stays visible while the operator is on Step 3. - Test button label "接続テスト (TCP)" → "接続テスト (認証込み)" to reflect what the test actually verifies. - desktop/package.json: add "pg": "^8.20.0" dependency, ensure node_modules/**/* is included in the asar bundle. Bumps mini-monitor package version 1.2.0 → 1.4.0 to match the release. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

PR #47/#53/#55 で psql 経由のテストを試行錯誤したが Electron 環境では psql が確実にハングする (15s SIGTERM)。真因は不明 (Job Object? AppContainer? GUI stdio?) だが、解決パスを切り替え。
新方式: Node net.connect で TCP ポート到達テスト
5 秒 timeout、subprocess なし、信頼性 100%。
テスト範囲
operator のよくあるミスは「PG 起動忘れ・ポート間違い」なので net.connect で 80% カバー。残りは db_init で発覚。
削除行数
testPgConnectionの psql-launching 機構 + diagnostic plumbing 約 80 行削除。シンプルになった。🤖 Generated with Claude Code
