 # Changelog

+## 2026-03-27 - 2.8.2 - fix(maven,tests)
+handle Maven Basic auth and accept deploy-plugin metadata/checksum uploads while stabilizing npm CLI test cleanup
+
+- Validate Maven tokens from Basic auth credentials by extracting the password portion before token validation.
+- Return successful responses for PUT requests to checksum and maven-metadata endpoints so Maven deploy uploads do not fail when files are auto-generated.
+- Improve npm CLI integration test isolation and cleanup by using a temporary test directory, copying per-package .npmrc files, and cleaning stale published packages before test runs.
+- Tighten test teardown by destroying the registry explicitly and simplifying package/install fixture generation.
+
+## 2026-03-24 - 2.8.1 - fix(registry)
+align OCI and RubyGems API behavior and improve npm search result ordering
+
+- handle OCI version checks on /v2 and /v2/ endpoints
+- return RubyGems versions JSON in the expected flat array format and update unyank coverage to use the HTTP endpoint
+- prioritize exact and prefix matches in npm search results
+- update documentation to reflect full upstream proxy support
+
+## 2026-03-24 - 2.8.0 - feat(core,storage,oci,registry-config)
+add streaming response support and configurable registry URLs across protocols
+
+- Normalize SmartRegistry responses to ReadableStream bodies at the public API boundary and add stream helper utilities for buffers, JSON, and hashing
+- Add streaming storage accessors for OCI, npm, Maven, Cargo, Composer, PyPI, and RubyGems downloads to reduce in-memory buffering
+- Make per-protocol registryUrl configurable so CLI and integration tests can use correct host and port values
+- Refactor OCI blob uploads to persist chunks in storage during upload and clean up temporary chunk objects after completion or expiry
+- Update tests and storage integration to use the new stream-based response model and smartstorage backend
+
+## 2025-12-03 - 2.7.0 - feat(upstream)
+Add dynamic per-request upstream provider and integrate into registries
+
+- Introduce IUpstreamProvider and IUpstreamResolutionContext to resolve upstream configs per request.
+- Add StaticUpstreamProvider implementation for simple static upstream configurations.
+- Propagate dynamic upstream provider through SmartRegistry and wire into protocol handlers (npm, oci, maven, cargo, composer, pypi, rubygems).
+- Replace persistent per-protocol upstream instances with per-request resolution: registries now call provider.resolveUpstreamConfig(...) and instantiate protocol-specific Upstream when needed.
+- Add IRequestActor to core interfaces and pass actor context (userId, ip, userAgent, etc.) to upstream resolution and storage/auth hooks.
+- Update many protocol registries to accept an upstreamProvider instead of IProtocolUpstreamConfig and to attempt upstream fetches only when provider returns enabled config.
+- Add utilities and tests: test helpers to create registries with upstream provider, a tracking upstream provider helper, StaticUpstreamProvider tests and extensive upstream/provider integration tests.
+- Improve upstream interfaces and cache/fetch contexts (IUpstreamFetchContext includes actor) and add StaticUpstreamProvider class to upstream module.
+
 ## 2025-11-27 - 2.6.0 - feat(core)
 Add core registry infrastructure: storage, auth, upstream cache, and protocol handlers

Juergen Kunz	1f0acf2825	fix(oci): remove /v2/ from internal route patterns and make upstream apiPrefix configurable The OCI handler had /v2/ baked into all regex patterns and Location headers. When basePath was set to /v2 (as in stack.gallery), stripping it removed the prefix that patterns expected, causing all OCI endpoints to 404. Now patterns match on bare paths after basePath stripping, working correctly regardless of the basePath value. Also adds configurable apiPrefix to OCI upstream class (default /v2) for registries behind reverse proxies with custom path prefixes.	2026-03-21 16:17:52 +00:00
Juergen Kunz	37e4c5be4a	fix(npm): decode URL-encoded package names after regex extraction Scoped npm packages use %2f encoding for the slash in URLs (e.g. @scope%2fpackage). Previously, the encoded name was used as-is for storage and packument metadata, causing npm install to fail with EINVALIDPACKAGENAME. Now each regex extraction point decodes the package name via decodeURIComponent while keeping the path encoded for correct regex matching.	2026-03-21 11:59:52 +00:00
