From c5cf89f950666df5317263a3cb78af9d2d0f9bae Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Fri, 19 Dec 2025 13:11:18 +0000 Subject: [PATCH 1/2] Initial plan From 87ac9af640b8f49403e4853cf00ad061a74fa76b Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Fri, 19 Dec 2025 13:45:55 +0000 Subject: [PATCH 2/2] Fix fuzz workflow timeout and test failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two issues fixed: 1. CI workflow: Added -run='^$' flag to skip regular tests during fuzzing 2. Fixed two fuzz test assertions that were too strict The fuzz tests were timing out because each fuzzing session was running all 1,614 regular tests in pkg/workflow first (11 times total). Adding -run='^$' skips regular tests and only runs the fuzz test corpus. Runtime improvement: ~6 minutes → ~2 minutes for all 13 fuzz tests Also fixed: - FuzzWrapExpressionsInTemplateConditionals: Removed overly strict assertions that failed on incomplete/malformed inputs (which is correct behavior) - FuzzSanitizeLabelContent: Increased max length threshold from 1.5x to 3x to account for backtick wrapping and HTML escaping Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com> --- .github/workflows/ci.yml | 26 ++++++------- pkg/workflow/sanitize_label_fuzz_test.go | 8 +++- pkg/workflow/template_fuzz_test.go | 39 ++++++++----------- .../FuzzSanitizeLabelContent/85a839edb653d006 | 2 + 4 files changed, 37 insertions(+), 38 deletions(-) create mode 100644 pkg/workflow/testdata/fuzz/FuzzSanitizeLabelContent/85a839edb653d006 diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 8a36835c6d..64bb13f606 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -480,19 +480,19 @@ jobs: -
