* Fix all golangci-lint issues across the codebase
Resolve 77 lint issues reported by golangci-lint with gocritic, gocognit,
gocyclo, maintidx, dupl, mnd, unparam, ireturn, goconst, and errcheck
enabled. Net reduction of ~175 lines through shared helpers and
deduplication.
* Suppress staticcheck SA1019 for intentional deprecated field usage
The Storage.Path field is deprecated but still read for backwards
compatibility with existing configs that haven't migrated to the URL field.
All handler metadata and proxy requests were using http.DefaultClient directly,
bypassing any timeout or transport configuration. Added an HTTPClient field to
the Proxy struct with a 30-second default timeout, and updated every handler
to use it for upstream HTTP requests.
POST endpoints (/api/outdated, /api/bulk) now reject bodies over 1 MB
using http.MaxBytesReader. Upstream metadata reads (npm, pypi, composer,
nuget, pub) now use io.LimitReader capped at 50 MB to prevent OOM from
unexpectedly large responses.
The debian and rpm handlers take the request path and pass it directly
to the upstream URL without checking for ".." segments. This could let
a client craft a request that reaches unintended upstream paths.
Add a containsPathTraversal check at the entry point of both handlers
and return 400 for any path containing ".." segments.
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.
Uses purl.MakePURLString() instead of fmt.Sprintf("pkg:...") for
correct namespace handling (npm scopes, Go module paths, Maven group
IDs) and percent-encoding. Replaces hand-rolled extractEcosystem and
inline PURL parsing in the bulk lookup fallback with purl.Parse().
Use the new client/ and fetch/ sub-packages from git-pkgs/registries
instead of the local upstream package. The fetcher, circuit breaker, and
resolver now live in registries where they can be shared across projects.
Depends on git-pkgs/registries#8.
The proxy can now use an existing git-pkgs database as a starting point.
Packages and versions tables match git-pkgs schema, using PURL-based
references instead of integer IDs. The proxy adds its own artifacts
table for caching functionality.
