 # Changelog
 
+## 2025-11-25 - 2.2.2 - fix(npm)
+Replace console logging with structured Smartlog in NPM registry and silence RubyGems helper error logging
+
+- Replaced console.log calls with this.logger.log (Smartlog) in ts/npm/classes.npmregistry.ts for debug/info/success events
+- Converted console.error in NpmRegistry.handleSearch to structured logger.log('error', ...) including the error message
+- Removed console.error from ts/rubygems/helpers.rubygems.ts; gem metadata extraction failures are now handled silently by returning null
+
+## 2025-11-25 - 2.2.1 - fix(core)
+Normalize binary data handling across registries and add buffer helpers
+
+- Add core/helpers.buffer.ts with isBinaryData and toBuffer utilities to consistently handle Buffer, Uint8Array, string and object inputs.
+- Composer: accept Uint8Array uploads, convert to Buffer before ZIP extraction, SHA-1 calculation and storage.
+- PyPI: accept multipart file content as Buffer or Uint8Array and normalize to Buffer before processing and storage.
+- Maven: normalize artifact body input with toBuffer before validation and storage.
+- OCI: improve upload id generation by using substring for correct random length.
+
+## 2025-11-25 - 2.2.0 - feat(core/registrystorage)
+Persist OCI manifest content-type in sidecar and normalize manifest body handling
+
+- Add getOciManifestContentType(repository, digest) to read stored manifest Content-Type
+- Store manifest Content-Type in a .type sidecar file when putOciManifest is called
+- Update putOciManifest to persist both manifest data and its content type
+- OciRegistry now retrieves stored content type (with fallback to detectManifestContentType) when serving manifests
+- Add toBuffer helper in OciRegistry to consistently convert various request body forms to Buffer for digest calculation and uploads
+
+## 2025-11-25 - 2.1.2 - fix(oci)
+Prefer raw request body for content-addressable OCI operations and expose rawBody on request context
+
+- Add rawBody?: Buffer to IRequestContext to allow callers to provide the exact raw request bytes for digest calculation (falls back to body if absent).
+- OCI registry handlers now prefer context.rawBody over context.body for content-addressable operations (manifests, blobs, and blob uploads) to preserve exact bytes and ensure digest calculation matches client expectations.
+- Upload flow updates: upload init, PATCH (upload chunk) and PUT (complete upload) now pass rawBody when available.
+
+## 2025-11-25 - 2.1.1 - fix(oci)
+Preserve raw manifest bytes for digest calculation and handle string/JSON manifest bodies in OCI registry
+
+- Preserve the exact bytes of the manifest payload when computing the sha256 digest to comply with the OCI spec and avoid mismatches caused by re-serialization.
+- Accept string request bodies (converted using UTF-8) and treat already-parsed JSON objects by re-serializing as a fallback.
+- Keep existing content-type fallback logic while ensuring accurate digest calculation prior to storing manifests.
+
+## 2025-11-25 - 2.1.0 - feat(oci)
+Support configurable OCI token realm/service and centralize unauthorized responses
+
+- SmartRegistry now forwards optional ociTokens (realm and service) from auth configuration to OciRegistry when OCI is enabled
+- OciRegistry constructor accepts an optional ociTokens parameter and stores it for use in auth headers
+- Replaced repeated construction of WWW-Authenticate headers with createUnauthorizedResponse and createUnauthorizedHeadResponse helpers that use configured realm/service
+- Behavior is backwards-compatible: when ociTokens are not configured the registry falls back to the previous defaults (realm: <basePath>/v2/token, service: "registry")
+
+## 2025-11-25 - 2.0.0 - BREAKING CHANGE(pypi,rubygems)
+Revise PyPI and RubyGems handling: normalize error payloads, fix .gem parsing/packing, adjust PyPI JSON API and tests, and export smartarchive plugin
+
+- Rename error payload property from 'message' to 'error' in PyPI and RubyGems interfaces and responses; error responses are now returned as JSON objects (body: { error: ... }) instead of Buffer(JSON.stringify(...)).
+- RubyGems: treat .gem files as plain tar archives (not gzipped). Use metadata.gz and data.tar.gz correctly, switch packing helper to pack plain tar, and use zlib deflate for .rz gemspec data.
+- RubyGems registry: add legacy Marshal specs endpoint (specs.4.8.gz) and adjust versions handler invocation to accept request context.
+- PyPI: adopt PEP 691 style (files is an array of file objects) in tests and metadata; include requires_python in test package metadata; update JSON API path matching to the package-level '/{package}/json' style used by the handler.
+- Fix HTML escaping expectations in tests (requires_python values are HTML-escaped in attributes, e.g. '&gt;=3.8').
+- Export smartarchive from plugins to enable archive helpers in core modules and helpers.
+- Update tests and internal code to match the new error shape and API/format behaviour.
+
+## 2025-11-25 - 1.9.0 - feat(auth)
+Implement HMAC-SHA256 OCI JWTs; enhance PyPI & RubyGems uploads and normalize responses
+
+- AuthManager: create and validate OCI JWTs signed with HMAC-SHA256 (header.payload.signature). Signature verification, exp/nbf checks and payload decoding implemented.
+- PyPI: improved Simple API handling (PEP-691 JSON responses returned as objects), Simple HTML responses updated, upload handling enhanced to support nested/flat multipart fields, verify hashes (sha256/md5/blake2b), store files and return 201 on success.
+- RubyGems: upload flow now attempts to extract gem metadata from the .gem binary when name/version are not provided, improved validation, and upload returns 201. Added extractGemMetadata helper.
+- OCI: centralized 401 response creation (including proper WWW-Authenticate header) and HEAD behavior fixed to return no body per HTTP spec.
+- SmartRegistry: use nullish coalescing for protocol basePath defaults to avoid falsy-value bugs when basePath is an empty string.
+- Tests and helpers: test expectations adjusted (Content-Type startsWith check for HTML, PEP-691 projects is an array), test helper switched to smartarchive for packaging.
+- Package.json: added devDependency @push.rocks/smartarchive and updated dev deps.
+- Various response normalization: avoid unnecessary Buffer.from() for already-serialized objects/strings and standardize status codes for create/upload endpoints (201).
+
+## 2025-11-24 - 1.8.0 - feat(smarts3)
+Add local smarts3 testing support and documentation
+
+- Added @push.rocks/smarts3 ^5.1.0 to devDependencies to enable a local S3-compatible test server.
+- Updated README with a new "Testing with smarts3" section including a Quick Start example and integration test commands.
+- Documented benefits and CI-friendly usage for running registry integration tests locally without cloud credentials.
+
+## 2025-11-23 - 1.7.0 - feat(core)
+Standardize S3 storage config using @tsclass/tsclass IS3Descriptor and wire it into RegistryStorage and plugins exports; update README and package dependencies.
+
+- Add @tsclass/tsclass dependency to package.json to provide a standardized IS3Descriptor for S3 configuration.
+- Export tsclass from ts/plugins.ts so plugin types are available to core modules.
+- Update IStorageConfig to extend plugins.tsclass.storage.IS3Descriptor, consolidating storage configuration typing.
+- Change RegistryStorage.init() to pass the storage config directly as an IS3Descriptor to SmartBucket (bucketName remains part of IStorageConfig).
+- Update README storage section with example config and mention IS3Descriptor integration.
+
 ## 2025-11-21 - 1.6.0 - feat(core)
 Add PyPI and RubyGems registries, integrate into SmartRegistry, extend storage and auth

+## 🧪 Testing with smarts3
+
+smartregistry works seamlessly with [@push.rocks/smarts3](https://code.foss.global/push.rocks/smarts3), a local S3-compatible server for testing. This allows you to test the registry without needing cloud credentials or external services.
+
+### Quick Start with smarts3
+
+```typescript
+import { Smarts3 } from '@push.rocks/smarts3';
+import { SmartRegistry } from '@push.rocks/smartregistry';
+
+// Start local S3 server
+const s3Server = await Smarts3.createAndStart({
+  server: { port: 3456 },
+  storage: { cleanSlate: true },
+});
+
+// Manually create IS3Descriptor matching smarts3 configuration
+// Note: smarts3 v5.1.0 doesn't properly expose getS3Descriptor() yet
+const s3Descriptor = {
+  endpoint: 'localhost',
+  port: 3456,
+  accessKey: 'test',
+  accessSecret: 'test',
+  useSsl: false,
+  region: 'us-east-1',
+};
+
+// Create registry with smarts3 configuration
+const registry = new SmartRegistry({
+  storage: {
+    ...s3Descriptor,
+    bucketName: 'my-test-registry',
+  },
+  auth: {
+    jwtSecret: 'test-secret',
+    tokenStore: 'memory',
+    npmTokens: { enabled: true },
+    ociTokens: {
+      enabled: true,
+      realm: 'https://auth.example.com/token',
+      service: 'my-registry',
+    },
+  },
+  npm: { enabled: true, basePath: '/npm' },
+  oci: { enabled: true, basePath: '/oci' },
+  pypi: { enabled: true, basePath: '/pypi' },
+  cargo: { enabled: true, basePath: '/cargo' },
+});
+
+await registry.init();
+
+// Use registry...
+// Your tests here
+
+// Cleanup
+await s3Server.stop();
+```
+
+### Benefits of Testing with smarts3
+
+- ✅ **Zero Setup** - No cloud credentials or external services needed
+- ✅ **Fast** - Local filesystem storage, no network latency
+- ✅ **Isolated** - Clean slate per test run, no shared state
+- ✅ **CI/CD Ready** - Works in automated pipelines without configuration
+- ✅ **Full Compatibility** - Implements S3 API, works with IS3Descriptor
+
+### Running Integration Tests
+
+```bash
+# Run smarts3 integration test
+pnpm exec tstest test/test.integration.smarts3.node.ts --verbose
+
+# Run all tests (includes smarts3)
+pnpm test
+```
