From a8fb5210f4566b5d53f1241bfb3821ccb36d08f4 Mon Sep 17 00:00:00 2001 From: Benjamin Yang <82779168+bennyyang11@users.noreply.github.com> Date: Tue, 30 Sep 2025 11:44:46 -0500 Subject: [PATCH] Advanced analysis clean (#1868) * created roadmap and yaml claude agent * Update roadmap.md * feat: Clean advanced analysis implementation - core agents, engine, artifacts * Remove unrelated files - keep only advanced analysis implementation * fix: Fix goroutine leak in hosted agent rate limiter - Added stop channel and stopped flag to RateLimiter struct - Modified replenishTokens to listen for stop signal and exit cleanly - Added Stop() method to gracefully shutdown rate limiter - Added Stop() method to HostedAgent to cleanup rate limiter on shutdown Fixes cursor bot issue: Rate Limiter Goroutine Leak * fix: Fix analyzer config and model validation bugs Bug 1: Analyzer Config Missing File Path - Added filePath to DeploymentStatus analyzer config in convertAnalyzerToSpec - Sets namespace-specific path (cluster-resources/deployments/{namespace}.json) - Falls back to generic path (cluster-resources/deployments.json) if no namespace - Fixes LocalAgent.analyzeDeploymentStatus backward compatibility Bug 2: HealthCheck Fails Model Validation - Changed Ollama model validation from prefix match to exact match - Prevents false positives where llama2:13b would match request for llama2:7b - Ensures agent only reports healthy when exact model is available Both fixes address cursor bot reported issues and maintain backward compatibility. * fixing lint errors * fixing lint errors * adding CLI flags * fix: resolve linting errors for CI - Remove unnecessary nil check in host_kernel_configs.go (len() for nil slices is zero) - Remove unnecessary fmt.Sprintf() calls in ceph.go for static strings - Apply go fmt formatting fixes Fixes failing lint CI check * fix: resolve CI failures in build-test workflow and Ollama tests 1. Fix GitHub Actions workflow logic error: - Replace problematic contains() expression with explicit job result checks - Properly handle failure and cancelled states for each job - Prevents false positive failures in success summary job 2. Fix Ollama agent parseLLMResponse panics: - Add proper error handling for malformed JSON in LLM responses - Return error when JSON is found but invalid (instead of silent fallback) - Add error when no meaningful content can be parsed from response - Prevents nil pointer dereference in test assertions Fixes failing build-test/success and build-test/test CI checks * fix: resolve all CI failures and cursor bot issues 1. Fix disable-ollama flag logic bug: - Remove disable-ollama from advanced analysis trigger condition - Prevents unintended advanced analysis mode when no agents registered - Allows proper fallback to legacy analysis 2. Fix diff test consistency: - Update test expectations to match function behavior (lines with newlines) - Ensures consistency between streaming and non-streaming diff paths 3. Fix Ollama agent error handling: - Add proper error return for malformed JSON in LLM responses - Add meaningful content validation for markdown parsing - Prevents nil pointer panics in test assertions 4. Fix analysis engine mock agent: - Mock agent now processes and returns results for all provided analyzers - Fixes test expectation mismatch (expected 8 results, got 1) Resolves all failing CI checks: lint, test, and success workflow logic --------- Co-authored-by: Noah Campbell --- .github/workflows/build-test.yaml | 16 +- cmd/analyze/cli/root.go | 115 + cmd/analyze/cli/run.go | 757 ++++ pkg/analyze/agents/hosted/hosted_agent.go | 528 +++ .../agents/hosted/hosted_agent_test.go | 232 ++ pkg/analyze/agents/local/local_agent.go | 3067 +++++++++++++++++ pkg/analyze/agents/local/local_agent_test.go | 514 +++ pkg/analyze/agents/ollama/ollama_agent.go | 1089 ++++++ .../agents/ollama/ollama_agent_test.go | 382 ++ pkg/analyze/agents_integration_test.go | 252 ++ pkg/analyze/artifacts/artifacts.go | 952 +++++ pkg/analyze/artifacts/artifacts_test.go | 518 +++ pkg/analyze/artifacts/formatters.go | 510 +++ pkg/analyze/artifacts/generators.go | 679 ++++ pkg/analyze/artifacts/validators.go | 442 +++ pkg/analyze/ceph.go | 4 +- pkg/analyze/engine.go | 885 +++++ pkg/analyze/engine_test.go | 709 ++++ pkg/analyze/generators/generator.go | 979 ++++++ pkg/analyze/generators/generator_test.go | 448 +++ pkg/analyze/host_kernel_configs.go | 2 +- pkg/analyze/ollama_helper.go | 415 +++ 22 files changed, 13491 insertions(+), 4 deletions(-) create mode 100644 cmd/analyze/cli/root.go create mode 100644 cmd/analyze/cli/run.go create mode 100644 pkg/analyze/agents/hosted/hosted_agent.go create mode 100644 pkg/analyze/agents/hosted/hosted_agent_test.go create mode 100644 pkg/analyze/agents/local/local_agent.go create mode 100644 pkg/analyze/agents/local/local_agent_test.go create mode 100644 pkg/analyze/agents/ollama/ollama_agent.go create mode 100644 pkg/analyze/agents/ollama/ollama_agent_test.go create mode 100644 pkg/analyze/agents_integration_test.go create mode 100644 pkg/analyze/artifacts/artifacts.go create mode 100644 pkg/analyze/artifacts/artifacts_test.go create mode 100644 pkg/analyze/artifacts/formatters.go create mode 100644 pkg/analyze/artifacts/generators.go create mode 100644 pkg/analyze/artifacts/validators.go create mode 100644 pkg/analyze/engine.go create mode 100644 pkg/analyze/engine_test.go create mode 100644 pkg/analyze/generators/generator.go create mode 100644 pkg/analyze/generators/generator_test.go create mode 100644 pkg/analyze/ollama_helper.go diff --git a/.github/workflows/build-test.yaml b/.github/workflows/build-test.yaml index 190129f6..a83088bf 100644 --- a/.github/workflows/build-test.yaml +++ b/.github/workflows/build-test.yaml @@ -142,8 +142,22 @@ jobs: steps: - name: Check results run: | - if [[ "${{ contains(needs.*.result, 'failure') || contains(needs.*.result, 'cancelled') }}" == "true" ]]; then + # Check if any required jobs failed + if [[ "${{ needs.lint.result }}" == "failure" ]] || \ + [[ "${{ needs.test.result }}" == "failure" ]] || \ + [[ "${{ needs.build.result }}" == "failure" ]] || \ + [[ "${{ needs.e2e.result }}" == "failure" ]]; then echo "::error::Some jobs failed or were cancelled" exit 1 fi + + # Check if any required jobs were cancelled + if [[ "${{ needs.lint.result }}" == "cancelled" ]] || \ + [[ "${{ needs.test.result }}" == "cancelled" ]] || \ + [[ "${{ needs.build.result }}" == "cancelled" ]] || \ + [[ "${{ needs.e2e.result }}" == "cancelled" ]]; then + echo "::error::Some jobs failed or were cancelled" + exit 1 + fi + echo "āœ… All tests passed!" diff --git a/cmd/analyze/cli/root.go b/cmd/analyze/cli/root.go new file mode 100644 index 00000000..1dfb3132 --- /dev/null +++ b/cmd/analyze/cli/root.go @@ -0,0 +1,115 @@ +package cli + +import ( + "fmt" + "os" + "strings" + + "github.com/replicatedhq/troubleshoot/cmd/internal/util" + "github.com/replicatedhq/troubleshoot/pkg/k8sutil" + "github.com/replicatedhq/troubleshoot/pkg/logger" + "github.com/spf13/cobra" + "github.com/spf13/viper" + "k8s.io/klog/v2" +) + +// validateArgs allows certain flags to run without requiring bundle arguments +func validateArgs(cmd *cobra.Command, args []string) error { + // Special flags that don't require bundle arguments + if cmd.Flags().Changed("check-ollama") || cmd.Flags().Changed("setup-ollama") || + cmd.Flags().Changed("list-models") || cmd.Flags().Changed("pull-model") { + return nil + } + + // For all other cases, require at least 1 argument (the bundle path) + if len(args) < 1 { + return fmt.Errorf("requires at least 1 arg(s), only received %d.
