From e26116e2cf5d1a0f0cdd99f05efbdd0865cb7660 Mon Sep 17 00:00:00 2001 From: treyt Date: Tue, 24 Feb 2026 21:32:09 -0600 Subject: [PATCH] Add webhook logging, pagination, middleware, migrations, and prod hardening - Webhook event logging repo and subscription webhook idempotency - Pagination helper (echohelpers) with cursor/offset support - Request ID and structured logging middleware - Push client improvements (FCM HTTP v1, better error handling) - Task model version column, business constraint migrations, targeted indexes - Expanded categorization chain tests - Email service and config hardening - CI workflow updates, .gitignore additions, .env.example updates Co-Authored-By: Claude Opus 4.6 --- .claude/settings.local.json | 12 +- .env.example | 21 +- .github/workflows/backend-ci.yml | 42 ++- .gitignore | 3 + cmd/api/main.go | 4 +- cmd/worker/main.go | 16 +- docs/go_to_prod.md | 260 ++++++++++++++++++ internal/config/config.go | 28 ++ internal/database/database.go | 22 +- internal/echohelpers/pagination.go | 32 +++ internal/echohelpers/pagination_test.go | 77 ++++++ internal/handlers/residence_handler.go | 20 +- internal/handlers/residence_handler_test.go | 2 +- .../handlers/subscription_webhook_handler.go | 59 ++++ internal/handlers/task_handler_test.go | 4 +- internal/i18n/i18n.go | 2 +- internal/integration/integration_test.go | 4 +- .../integration/subscription_is_free_test.go | 2 +- internal/middleware/logger.go | 53 ++++ internal/middleware/request_id.go | 43 +++ internal/models/task.go | 3 + internal/push/client.go | 25 +- internal/repositories/subscription_repo.go | 36 ++- internal/repositories/task_repo.go | 139 ++++++++-- internal/repositories/task_repo_test.go | 18 +- internal/repositories/webhook_event_repo.go | 54 ++++ .../repositories/webhook_event_repo_test.go | 104 +++++++ internal/router/router.go | 14 +- internal/services/email_service.go | 24 +- internal/services/task_service.go | 34 ++- .../task/categorization/chain_breakit_test.go | 241 ++++++++++++++++ internal/task/categorization/chain_test.go | 256 +++++++++++++++++ internal/testutil/testutil.go | 1 + internal/worker/jobs/handler.go | 5 + migrations/000012_webhook_event_log.down.sql | 1 + migrations/000012_webhook_event_log.up.sql | 9 + .../000013_business_constraints.down.sql | 5 + migrations/000013_business_constraints.up.sql | 19 ++ .../000014_task_version_column.down.sql | 1 + migrations/000014_task_version_column.up.sql | 1 + migrations/000015_targeted_indexes.down.sql | 3 + migrations/000015_targeted_indexes.up.sql | 14 + migrations/012_webhook_event_log.down.sql | 1 + migrations/012_webhook_event_log.up.sql | 9 + migrations/013_business_constraints.down.sql | 5 + migrations/013_business_constraints.up.sql | 31 +++ migrations/014_task_version_column.down.sql | 1 + migrations/014_task_version_column.up.sql | 1 + migrations/015_targeted_indexes.down.sql | 3 + migrations/015_targeted_indexes.up.sql | 14 + 50 files changed, 1681 insertions(+), 97 deletions(-) create mode 100644 docs/go_to_prod.md create mode 100644 internal/echohelpers/pagination.go create mode 100644 internal/echohelpers/pagination_test.go create mode 100644 internal/middleware/logger.go create mode 100644 internal/middleware/request_id.go create mode 100644 internal/repositories/webhook_event_repo.go create mode 100644 internal/repositories/webhook_event_repo_test.go create mode 100644 internal/task/categorization/chain_breakit_test.go create mode 100644 migrations/000012_webhook_event_log.down.sql create mode 100644 migrations/000012_webhook_event_log.up.sql create mode 100644 migrations/000013_business_constraints.down.sql create mode 100644 migrations/000013_business_constraints.up.sql create mode 100644 migrations/000014_task_version_column.down.sql create mode 100644 migrations/000014_task_version_column.up.sql create mode 100644 migrations/000015_targeted_indexes.down.sql create mode 100644 migrations/000015_targeted_indexes.up.sql create mode 100644 migrations/012_webhook_event_log.down.sql create mode 100644 migrations/012_webhook_event_log.up.sql create mode 100644 migrations/013_business_constraints.down.sql create mode 100644 migrations/013_business_constraints.up.sql create mode 100644 migrations/014_task_version_column.down.sql create mode 100644 migrations/014_task_version_column.up.sql create mode 100644 migrations/015_targeted_indexes.down.sql create mode 100644 migrations/015_targeted_indexes.up.sql diff --git a/.claude/settings.local.json b/.claude/settings.local.json index f6a675a..10dc9a4 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -2,7 +2,17 @@ "permissions": { "allow": [ "WebSearch", -
