From 43a03c168c8c51244a3c5fdc255168b0b0ddce9c Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Mon, 23 Mar 2026 17:36:25 -0400 Subject: [PATCH] fix: Go 1.25 upgrade, codebase audit fixes, MCP server tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Upgrade from Go 1.22 to 1.25 (minimum for MCP SDK, actively supported). CI updated to match. Codebase audit fixes: - Local CA parseIP() now uses net.ParseIP — IP SANs no longer silently dropped - Nil pointer guards in agent.go GetWorkWithTargets for target/cert enrichment - MCP CreateCertificateInput marks owner_id/team_id as required - NGINX connector uses CombinedOutput() — captures diagnostic output on failure - Jobs handler validates JSON decode on rejection body — returns 400 on malformed - CRL/OCSP handlers propagate requestID for error tracing MCP server tests (26 tests): - client_test.go: HTTP client coverage (GET/POST/PUT/DELETE, auth, 204, errors, binary) - tools_test.go: tool registration, pagination, end-to-end flows with mock API Co-Authored-By: Claude Opus 4.6 --- .github/workflows/ci.yml | 4 +- go.mod | 2 +- internal/api/handler/certificates.go |
