From 53aa4d0344f25a1864f0bfd9b1544b9f6751b5c3 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 1 Dec 2025 00:14:22 +0100 Subject: [PATCH] Security Hardening and GraphQL Caching (#69) * feat: add security middleware, graphql apq, and improved linting - Add RateLimit, RequestValidation, and CORS middleware. - Configure middleware chain in API server. - Implement Redis cache for GraphQL Automatic Persisted Queries. - Add .golangci.yml and fix linting issues (shadowing, timeouts). * feat: security, caching and linting config - Fix .golangci.yml config for govet shadow check - (Previous changes: Security middleware, GraphQL APQ, Linting fixes) * fix: resolve remaining lint errors - Fix unhandled errors in tests (errcheck) - Define constants for repeated strings (goconst) - Suppress high complexity warnings with nolint:gocyclo - Fix integer overflow warnings (gosec) - Add package comments - Split long lines (lll) - Rename Analyse -> Analyze (misspell) - Fix naked returns and unused params --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> --- .golangci.yml | 60 ++++++++++ cmd/api/main.go | 62 ++++++---- cmd/api/server.go | 25 +++- cmd/cli/commands/.bleve_migration_checkpoint | 1 + cmd/cli/commands/bleve_migrate.go | 24 ++-- .../commands/bleve_migrate_edge_cases_test.go | 21 ++-- cmd/cli/commands/bleve_migrate_test.go | 20 ++-- cmd/cli/commands/doc.go | 2 + cmd/cli/internal/bootstrap/bootstrap_test.go | 8 +- cmd/cli/internal/bootstrap/doc.go | 2 + go.mod | 4 +- internal/app/auth/doc.go | 2 + internal/app/auth/main_test.go | 1 + internal/app/user/commands.go | 1 + internal/app/work/commands.go | 1 + .../jobs/linguistics/analysis_repository.go | 5 +- internal/jobs/linguistics/doc.go | 2 + .../jobs/linguistics/language_detector.go | 14 ++- internal/jobs/linguistics/lemmatizer.go | 1 + internal/jobs/linguistics/phonetic_encoder.go | 1 + internal/jobs/linguistics/poetic_analyzer.go | 19 ++- .../jobs/linguistics/poetic_analyzer_test.go | 6 +- internal/jobs/linguistics/pos_tagger.go | 47 ++++++-- internal/jobs/linguistics/text_analyzer.go | 1 + internal/jobs/linguistics/text_utils.go | 2 +- internal/platform/cache/cache.go | 4 +- internal/platform/cache/cache_test.go | 110 +++++++++--------- internal/platform/cache/graphql_adapter.go | 29 +++++ internal/platform/cache/redis_cache.go | 13 ++- internal/platform/cache/redis_cache_test.go | 5 +- internal/platform/http/middleware.go | 86 ++++++++++++++ internal/platform/http/rate_limiter.go | 4 +- internal/platform/http/rate_limiter_test.go | 13 ++- internal/platform/search/doc.go | 2 + internal/platform/search/weaviate_wrapper.go | 16 ++- 35 files changed, 453 insertions(+), 161 deletions(-) create mode 100644 .golangci.yml create mode 100644 cmd/cli/commands/.bleve_migration_checkpoint create mode 100644 cmd/cli/commands/doc.go create mode 100644 cmd/cli/internal/bootstrap/doc.go create mode 100644 internal/app/auth/doc.go create mode 100644 internal/jobs/linguistics/doc.go create mode 100644 internal/platform/cache/graphql_adapter.go create mode 100644 internal/platform/http/middleware.go create mode 100644 internal/platform/search/doc.go diff --git a/.golangci.yml b/.golangci.yml new file mode 100644 index 0000000..31790a1 --- /dev/null +++ b/.golangci.yml @@ -0,0 +1,60 @@ +run: + timeout: 5m + tests: true + +linters-settings: + govet: + enable: + -
