From 08e9043c61d16cbdd12ad1a4c905f1417db68cce Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 5 Mar 2026 10:15:35 +0000 Subject: [PATCH 1/4] fix(core): prevent analyze results from being silently empty The bounded Promise pool in Nitpicker.analyze() did not catch individual task errors. When runInWorker() rejected (e.g., worker crash, OOM, plugin import failure), the rejection propagated to Promise.race/Promise.all, crashing the entire analyze flow before saving any results to the archive. Changes: - Wrap each page analysis task in try-catch so a single page failure does not abort the entire plugin run - Emit 'error' events for individual page failures with URL context - Emit a warning when a plugin produces no page data at all - Add try-catch in worker.ts to send a graceful 'finish' message with null result when runner() throws, instead of crashing - Add unit tests covering error resilience and empty-result warnings Closes #35 https://claude.ai/code/session_01GGS8WVVNwxG2ueyEdyVUYW --- .../@nitpicker/core/src/nitpicker.spec.ts | 258 +++++++++++++++++- packages/@nitpicker/core/src/nitpicker.ts | 125 +++++---- packages/@nitpicker/core/src/worker/worker.ts | 32 ++- 3 files changed, 356 insertions(+), 59 deletions(-) diff --git a/packages/@nitpicker/core/src/nitpicker.spec.ts b/packages/@nitpicker/core/src/nitpicker.spec.ts index 11d2786..65224ef 100644 --- a/packages/@nitpicker/core/src/nitpicker.spec.ts +++ b/packages/@nitpicker/core/src/nitpicker.spec.ts @@ -1,4 +1,6 @@ -import type { Config } from './types.js';

for analyze error handling - Add try-catch to Phase 2 (eachUrl) so a single plugin failure does not abort remaining URL checks or prevent report saving - Propagate worker error field in run-in-worker.ts: when worker.ts sends { error }, reject the promise instead of silently resolving null - Re-throw plugin errors from page-analysis-worker.ts instead of swallowing them, so they propagate through worker -> main thread -> error event chain for proper visibility - Replace allViolations.push(...spread) with for-of loop to avoid potential stack overflow with very large violation arrays - Strengthen test: verify exact error event count in "emits error" test - Add tests: eachUrl error resilience, multi-plugin partial failure, getHtml() rejection handling
