remotes: add mirrorlist for round-robin + failover across mirrors (rpm/deb/apk)
OS package remotes (rpm/deb/apk) fetch many small files and benefit from
spreading upstream load across mirrors and surviving a mirror outage. A
remote may now set a `mirrorlist` of additional upstream base URLs; the
effective upstream pool is [base_url] + mirrorlist, which the shared proxy
engine load-balances round-robin and, on a network error/timeout/5xx,
fails over to the next mirror before returning an error. Because selection
happens in the engine, it works for every provider that reaches upstream.
Backward compatible: `base_url` stays a plain string that providers read
unchanged, and a remote with no mirrorlist behaves exactly as today
(single attempt, same error path).
- add models.Remote.Mirrorlist ([]string, json "mirrorlist,omitempty") and
UpstreamPool() = [base_url] + mirrorlist; ValidateMirrorlist enforces
remote repo_type + package_type in {rpm, deb, alpine} and http/https URLs
- v2 create/update: reject a mirrorlist on any other repo (400); base_url
remains required for remotes
- persist mirrorlist in a new additive `mirrorlist TEXT[]` column
(remoteCols/scanRemote/CreateRemote/UpdateRemote); base_url column
unchanged
- engine: per-remote round-robin cursor over the pool; wrap the
fetch/head/revalidate upstream calls in a failover loop that narrows the
remote to one selected mirror per attempt; only network errors and 5xx
fail over (404/403/... return as-is); circuit breaker stays keyed per
remote and trips only after all mirrors fail
- tests: model JSON round-trip + validation gating, engine
round-robin/failover/no-mirrorlist-unchanged, DB mirrorlist round-trip,
and a docker acceptance suite (round-robin across two mock upstreams,
failover past a dead primary, no-mirrorlist regression, and a real dnf
makecache+install through a two-mirror rpm remote whose base_url is dead)
Least-connections and a per-remote strategy selector are a follow-up PR.

Add Alpine/apk local repository support (#114)
## Why The alpine provider only supported remote (proxy) repositories, so there was no way to publish first-party `.apk` packages the way `rpm-local` and `deb-local` already allow. This extends the existing alpine provider into a real apk repository: uploaded `.apk` files are parsed in pure Go and a per-arch `APKINDEX.tar.gz` is generated on demand, at parity with rpm repodata and deb Packages generation. (The metadata-only `github_alpine` type is a separate follow-up and is not part of this PR.) ## How - Implements `LocalUploader` / `LocalIndexer` / `PostUploadHook` / `PostDeleteHook` on the existing `alpine` provider, leaving the remote proxy methods (`UpstreamURL`/`ContentType`/`AuthHeaders`/`RewriteResponse`/`Classify`) intact. - Parses the `.apk` (up to three concatenated, independently gzipped tar streams) in pure Go: locates the control stream by its `.PKGINFO` member, reads the `key = value` fields, and computes the apk pull checksum `C:` = `Q1` + base64(sha1(**control gzip stream bytes**)) — the sha1 of the second gzip member, not of the whole file. - Derives arch from `.PKGINFO` and records download size (`S:` blob size) and installed size (`I:` from `.PKGINFO size`). - Generates an **unsigned** per-arch `APKINDEX.tar.gz` = gzip(tar(`APKINDEX`)) filtered by requested arch (clients use `--allow-untrusted`, matching rpm `gpgcheck=0` / deb `[trusted=yes]`), applying the same dot-segment normalization as deb so `./<arch>/APKINDEX.tar.gz` resolves. Non-index / `.apk` paths return `false` so the generic file streamer serves the stored blob. - Adds `AlpineMetadata` plus **separate** `AlpineMetadataStore` / `AlpineMetadataReader` / `AlpineMetadataDeleter` interfaces (type-asserted from the generic hooks) so the shared rpm/deb metadata interfaces and their test doubles are untouched. - Adds the `alpine_metadata` table (keyed by `repo_name` + `file_path`, per-arch index) and its `Insert`/`Delete`/`List` DB methods. - Adds `testsupport.MinimalApk`, unit tests (`.PKGINFO` parse, Q1 checksum over the control stream, per-arch filtering, empty-field omission, `./` dot-segment handling, ValidateUpload accept/reject), and a `dockere2e` `TestLocalAlpineIndex`. ## Consumption `/etc/apk/repositories` line = `<url>/api/v1/local/<name>` (apk appends `/<arch>/APKINDEX.tar.gz`); `apk update --allow-untrusted && apk add --allow-untrusted <pkg>`. Packages live at `/api/v1/local/<name>/<arch>/<file>.apk`. ## Verification `go build ./...`, `go vet ./...` (incl. `-tags dockere2e`), `go mod tidy` (no change), `make test` (`-race`), and `pre-commit run --all-files` all pass.

Add deb (Debian/apt) local and remote repository support (#111)
Brings Debian/apt to artifactapi with feature parity to the existing rpm support (local + remote), so `.deb` packages can be hosted as a flat apt repo and a Debian/Ubuntu mirror can be cached through the proxy.
- Adds `deb` to the package-type enum and registers a new `internal/provider/deb` provider.
- Classifies `.deb` blobs immutable and the apt index surface (`Packages`, `Release`, `InRelease`, `dists/`, by-hash) mutable so the caching engine revalidates it.
- Parses the `.deb` in pure Go (ar archive to `control.tar.{gz,xz,zst}` to `./control`), storing the raw control stanza plus computed size/md5/sha256 as `deb_metadata`.
- Serves a flat apt repo (`deb [trusted=yes] .../ ./`): generates `Packages`, `Packages.gz` and an unsigned `Release` (returns 404 for `InRelease`/`Release.gpg`), mirroring rpm unsigned repodata / gpgcheck=0 trust model.
- Proxies a remote mirror via `UpstreamURL`/`ContentType`/`AuthHeaders` (HTTP Basic).
- Adds the `deb_metadata` table to `migrate()`, DB access methods, a `MinimalDeb` pure-Go fixture, unit tests, and a `dockere2e` `TestLocalDebRepo`.

feat: serve local docker repos as a real registry (#103)
ci/woodpecker/tag/docker Pipeline was successful
## Why Local `docker` repos had no write path — the `/v2` Docker Registry API only proxied to upstreams. This makes a local docker repo a genuine container registry so `docker push`/`docker pull` (and podman/skopeo/buildah) work against it directly, matching the project principle that a local repo is *the real thing* rather than a mirror. ## Changes - Implement the Docker Registry HTTP API V2 read/write half for local docker repos: blob uploads (monolithic and chunked POST/PATCH/PUT), manifest push, `tags/list`, and blob/manifest GET/HEAD. - Store blobs and manifests through the existing content-addressable store; keep a `local_files` reference per (repo, image) so the GC does not reap them. Tags are mutable (`UpsertLocalFile`); digests and blobs are immutable. - Dispatch `/v2` reads to the local handler for local docker repos and fall through to the upstream proxy otherwise; writes are local-docker only. - Add `UpsertLocalFile` for mutable tag references. - Cover the push/pull round-trip with a dockerised e2e test and unit-test the registry path parser. Document the registry in the README. ## Verification - `scripts/docker-e2e.sh` passes, including the new `TestLocalDockerPushPull`. - Verified a real end-to-end round-trip with skopeo against a live instance: pushed `hello-world`, pulled it back, loaded it into the docker daemon, and ran it successfully.

test: comprehensive dockerised end-to-end suite (#97)
Adds a black-box e2e suite that runs against the **built container image** via docker-compose (complementing the in-process `e2e/` testcontainers suite). ## What it does `make docker-e2e` → `scripts/docker-e2e.sh`: builds the image, brings up the full stack (postgres, redis, minio, artifactapi) plus a static nginx **mock upstream** for hermetic caching, waits for `/health`, runs `go test -tags=dockere2e ./e2e-docker/...`, and tears everything down. ## Coverage - **Repository lifecycle** — add / change / delete for remote, local and virtual repos. - **Caching** — one immutable artifact for **each of the 10 remote package types** (generic, docker, helm, pypi, npm, rpm, alpine, puppet, terraform, goproxy) proxied through the mock upstream: first fetch `X-Artifact-Source: remote`, second `cache`, bytes verified against the origin fixture. - **Local uploads** — generic (upload/download), pypi (wheel + generated `simple/` index), rpm (real package + **automatic repodata** generation). - **Virtual repositories** — pypi simple-index merge and helm `index.yaml` merge across two members. ## Notes - The artifactapi host port is parameterised (`ARTIFACTAPI_PORT`, default `8000`; the e2e run uses `8001`) so it does not collide with a locally-running instance. This is the only change to the production `docker-compose.yml`. - Fixtures under `e2e-docker/fixtures/` are real package files (incl. a real RPM so repodata parsing works); a `.gitignore` negation tracks them over the global ignore of those extensions. ## Validation Ran `make docker-e2e` locally: **all suites pass** against the containerised product. --------- Co-authored-by: BenVincent <benvin@main.unkin.net> Reviewed-on: #97 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net> |
