Cached metadata is now served directly within a configurable TTL window
(default 5m) without contacting upstream, reducing latency and upstream
load. When upstream is unreachable and the cache is past its TTL, stale
content is served with a Warning: 110 header per RFC 7234.
New config: `metadata_ttl` (YAML) / `PROXY_METADATA_TTL` (env).
Set to "0" to always revalidate with upstream.
- ProxyCached now stores upstream Last-Modified in the cache and uses it
(along with ETag) for conditional request handling, returning 304 when
client validators match. Adds Content-Length to cached responses.
- Handlers calling FetchOrCacheMetadata (pypi, composer, pub, nuget) now
check for ErrUpstreamNotFound and return 404 instead of 502, matching
the existing npm and cargo behavior.
- Mirror jobs report live progress via a periodic callback while running,
so API polls return real counts instead of zeroed progress.
- Registry mirroring removed from CLI flags, API acceptance, README, and
docs since every enumerator was a stub returning "not yet implemented".
- Added tests for the conditional metadata path (ETag/If-None-Match,
Last-Modified/If-Modified-Since, 304 responses, header omission).
- Fix race where runJob could overwrite canceled state set by Cancel()
- Fix Debian ecosystem name inconsistency ("deb" -> "debian")
- Stream metadata responses when caching is disabled to avoid buffering
- Add metadata_cache table to initial schema strings for consistency
- Gate mirror API behind mirror_api config flag (disabled by default)
- Fix goconst lint in metadata_cache_test.go
Add a `proxy mirror` CLI command and `/api/mirror` API endpoints that
pre-populate the cache from various input sources: individual PURLs,
SBOM files (CycloneDX and SPDX), or full registry enumeration.
The mirror reuses the existing handler.Proxy.GetOrFetchArtifact()
pipeline so cached artifacts are identical to those fetched on demand.
A bounded worker pool controls download parallelism.
Metadata caching is opt-in via `cache_metadata: true` in config (or
PROXY_CACHE_METADATA=true). The mirror command always enables it. When
enabled, upstream metadata responses are stored for offline fallback
with ETag-based conditional revalidation.
New internal/mirror package with Source interface, PURLSource,
SBOMSource, RegistrySource, and async JobStore. New metadata_cache
database table for offline metadata serving.
Decode the Hex registry protobuf format, filter releases by fetching
timestamps from the Hex HTTP API (hex.pm/api/packages/{name}), and
re-encode without the original signature.
The protobuf handling uses protowire for low-level encoding/decoding
of the Signed wrapper, Package, and Release messages. Timestamps come
from the inserted_at field in the JSON API response.
Since the proxy re-encodes the payload without the original signature,
users need to disable registry signature verification.
Filter versions from the compact index (/info/{name}) by fetching
timestamps from the versions API (/api/v1/versions/{name}.json).
Both requests run concurrently to minimize latency. If the versions
API is unavailable, the compact index is proxied unfiltered.
Handles platform-specific versions (e.g. 1.0.0-java) by matching
the compact index format.
* Add cooldown support for Conda
Filter entries from Conda repodata.json based on the timestamp field
(milliseconds since epoch). Filters both packages and packages.conda
sections. When cooldown is disabled, repodata requests are proxied
directly without parsing.
* Update README table to mark Conda cooldown support
* Add cooldown support for NuGet
Filter versions from NuGet registration pages based on the
catalogEntry.published timestamp. Handles both RFC3339 and NuGet's
fractional-second timestamp formats. When cooldown is disabled,
registration requests are proxied directly without parsing.
* Update README table to mark NuGet cooldown support
* Fix Composer minified metadata expansion and namespaced package routing
Packagist serves metadata in a minified format where only the first version
entry has all fields and subsequent entries inherit from the previous one.
The proxy was passing this through without expanding it, which meant cooldown
filtering could break the inheritance chain (losing fields like `name`) and
`~dev` sentinel markers were silently dropped.
The proxy now expands the minified format before filtering and rewriting,
ensuring every version entry is self-contained.
Web UI and API routes used single-segment chi URL params for package names,
which broke for Composer's `vendor/name` format. `/package/composer/monolog/monolog`
would match the version show route instead of the package show route.
All `/package/` and related API routes now use wildcard paths with a
`resolvePackageName` helper that tries increasingly longer path prefixes as
package names via DB lookup, correctly handling namespaced packages across
all endpoints (show, version, browse, compare, vulns).
Fixes#61, fixes#62
* Add namespaced package routing tests for all affected ecosystems
Verifies the wildcard routing handles slashes in package names for
npm (@babel/core), Go modules (github.com/stretchr/testify),
OCI images (library/nginx), Conda (conda-forge/numpy), and
Conan (zlib/1.2.13@demo/stable).
* Regenerate swagger docs after route refactor
The swagger annotations for the old per-endpoint handlers were removed
during the wildcard routing refactor. Regenerate to match current state.
* Track applied migrations to skip column checks on startup
Add a migrations table that records which migrations have been applied.
On boot, load the set of applied names in one query and only run new ones.
A fully migrated database now does 1 query instead of ~12 HasColumn/HasTable
checks.
Fresh databases created via CreateSchema record all migrations as already
applied. Old databases get the migrations table on first MigrateSchema call
and each migration is recorded after it runs.
Closes#54
* Add benchmark for MigrateSchema on fully migrated database
* Optimize MigrateSchema to single query for fully migrated databases
Skip HasTable/HasColumn checks when the migrations table already exists.
A fully migrated database now does one SELECT instead of ~12 individual
column and table checks.
* Add migration docs and link from architecture
* Add test for upgrade from fully migrated database without migrations table
* Fix startup message and add connectivity check for S3 storage
When S3 storage is configured, the startup log incorrectly showed the
default local path (./cache/artifacts) instead of the actual S3 URL.
This also adds a lightweight connectivity check at startup so bad
credentials or endpoints fail immediately rather than on first request.
Add URL() and Close() to the Storage interface so all backends report
their URL and can be cleaned up properly. Rename the stats JSON field
from storage_path to storage_url. Close storage in error paths and
during graceful shutdown.
Fixes#49
* Fix Windows test assertion for file:// URL format
OpenBucket normalizes Windows paths to file:///C:/path (three slashes)
but the test expected file://C:/path (two slashes).
Add web interface section to README describing all pages (dashboard,
package browser, source browser, version diff). Add monitoring section
with the full Prometheus metrics table and scrape config. Add cooldown
column to the registry support table. Update architecture doc with
accurate database schema including all columns and indexes, and add
entries for metrics, cooldown, and enrichment packages.
Hides package versions published too recently from metadata responses,
giving the community time to spot malicious releases. Configurable
per-ecosystem and per-package with duration overrides. Supported for
npm, PyPI, pub.dev, and Composer.
