From b9d15c5dbfb8f88a49c92fbe64e84e790dfc7e31 Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Sat, 2 May 2026 00:29:09 +0000 Subject: [PATCH] repo,service: introduce WithinTx and atomic audit rows for issue/renew/revoke MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the #3 acquisition-readiness blocker from the 2026-05-01 issuer coverage audit (Part 1.5 finding #1: audit row not transactional with issuance). AuditRepository.Create previously ran on the package-level *sql.DB while the certificate insert / version insert / revocation insert ran on independent connections — a failed audit INSERT after a successful operation INSERT was silently lost. SOX §404 over IT general controls, PCI-DSS §10 audit logging, HIPAA §164.312(b) audit controls, and CA/B Forum Baseline Requirements §5.4.1 audit log records all presume audit-with-operation atomicity. Design — Option A (Querier abstraction). The chosen pattern: a shared repository.Querier interface (subset of *sql.DB and *sql.Tx) plus a postgres.WithinTx helper that begins a tx, runs fn, commits on nil error, rolls back on error or panic, and returns the wrapped result. Repository methods that participate in a service-layer transaction expose a *WithTx variant taking repository.Querier; the bare methods remain for stand-alone use. A repository.Transactor abstracts the "begin tx, run fn, commit/rollback" lifecycle so service-layer code runs multi-write operations atomically without holding *sql.DB directly. Option B (UnitOfWork) was considered but adds boilerplate without behavioral benefit for the current scope. Option C (context-carried tx) was explicitly rejected — it hides the transactional boundary from the type system, reproducing the class of bug we're fixing. This commit: - Adds internal/repository/querier.go with the Querier interface (compile-time guards that *sql.DB and *sql.Tx satisfy it) and the Transactor interface for service-layer use. - Adds internal/repository/postgres/tx.go with the WithinTx helper (begin/fn/commit/rollback with panic recovery) and a transactor type that satisfies repository.Transactor. - Adds CreateWithTx variants on AuditRepository, CertificateRepository (Create + Update + CreateVersion), and RevocationRepository. Existing bare methods now delegate to the *WithTx variant using the package-level *sql.DB so existing call sites are behavior-preserving. - Updates repository/interfaces.go: AuditRepository, CertificateRepository, and RevocationRepository declare the new *WithTx methods. Adds an atomicity contract doc-comment on AuditRepository pointing at WithinTx + the audit blocker. - Adds AuditService.RecordEventWithTx, mirroring RecordEvent but routing through CreateWithTx so the audit row is part of the caller's transaction. Same redaction + marshalling contract. - Refactors three audit-emitting service paths to use Transactor.WithinTx when SetTransactor was wired, with a legacy fallback for backward compat: * CertificateService.Create — cert insert + audit row in one tx. * RevocationSvc.RevokeCertificateWithActor — cert status update + revocation row + audit row in one tx. The OCSP cache invalidate remains best-effort (out of scope per the prompt). * RenewalService CompleteServerRenewal — cert version insert + cert update + audit row in one tx. Job status update stays outside the audit-atomicity scope (job state lives outside the operator-facing audit trail). - Adds SetTransactor on CertificateService, RevocationSvc, and RenewalService. cmd/server/main.go wires a single Transactor instance shared across all three so all audit-emitting paths run their writes in transactions backed by the same *sql.DB handle. - Updates 5 mock implementations to satisfy the new interface methods: mockCertRepo (testutil_test.go), mockCertRepoWithGetError (shortlived_test.go), fakeRevocationRepo (crl_cache_test.go), intuneE2EAuditRepo (scep_intune_e2e_test.go), and the integration- test mocks (lifecycle_test.go: mockCertificateRepository, mockAuditRepository, mockRevocationRepository). All *WithTx mocks ignore the Querier and delegate to the bare method (mocks have no DB; in-memory state is shared regardless of "tx"). - Adds a service-layer test mockTransactor with BeginTxErr and CommitErr knobs so the atomic-audit tests can assert error propagation through the transactional boundary. - Adds internal/repository/postgres/tx_test.go: unit-level test that WithinTx surfaces "begin tx" wrap when BeginTx fails, and that Transactor.WithinTx delegates correctly. Real-Postgres rollback semantics are covered by the testcontainers tests in the postgres package — sandbox disk pressure prevented adding a sqlmock dep for the in-fn / commit-failure unit test, so those scenarios are exercised through atomic_audit_test.go using the mockTransactor's CommitErr / BeginTxErr fields. - Adds internal/service/atomic_audit_test.go: * TestCertificateService_Create_AtomicWithTx — asserts audit insert failure inside the tx surfaces as the operation's error (closes the blocker contract). * TestCertificateService_Create_LegacyPathLogs — pins the backward-compat behavior when SetTransactor isn't wired: audit failure is logged-not-failed, matching pre-fix. * TestCertificateService_Create_TransactorBeginFailure — BeginTx error path: operation fails, no cert insert, no audit insert. * TestCertificateService_Create_TransactorCommitFailure — Commit error after successful in-fn writes surfaces as the operation's error. Real Postgres can fail Commit on serialization conflicts; the service must report this. Out of scope (separate follow-up commits, same shape): - Issuer CRUD audit atomicity. - Target CRUD audit atomicity. - Agent retire (already transactional via RetireAgentWithCascade; verified, not changed). - Renewal-policy CRUD audit atomicity. - Owner/team/agent-group CRUD audit atomicity. - Discovery / health-check audit atomicity.
