From ff8a39fed626cbeb0f6006820b98944f14882a6e Mon Sep 17 00:00:00 2001 From: Wael Nasreddine Date: Wed, 11 Feb 2026 08:04:34 -0800 Subject: [PATCH 1/2] fix: Fix test data generation and skip signature verification Update GenerateEntry to create valid narinfo with proper References format. Remove invalid fake signature since generated test entries cannot be signed without the private key. Update distributed tests to skip public key verification when using generated test entries. Changes: - testdata/generator.go: - Remove invalid fake signature (test-cache:1:fakesignature==) - Update References field to format: narInfoHash-generated-test - Add comment explaining why signatures are not included - pkg/cache/cache_distributed_test.go: - Update all 4 distributed test functions to pass nil for upstream options - Tests affected: testDistributedDownloadDeduplication, testDistributedConcurrentReads, testLargeNARConcurrentDownloadScenario, testCDCProgressiveStreamingDuringChunking - Add comments explaining why public key verification is skipped This fixes narinfo parsing failures in distributed tests where GetNar was unable to fetch narinfo for generated test entries due to invalid format.
