CONFIG_PATH now accepts a directory path (all *.yaml files merged) or a
main file with a config_dir key pointing to a drop-in directory. Remotes
are merged alphabetically across files; later files win on conflicts.
Add per-remote quarantine support: when quarantine_new=true and quarantine_days=N,
immutable artifacts published within the last N days are blocked with 404 until
the quarantine window expires.
- ConfigManager.get_quarantine_config() reads quarantine_new/quarantine_days
- RedisCache.store/get_artifact_published() persist Last-Modified per artifact
- proxy._check_quarantine() enforces the window; fails open when date is unknown
- proxy._fetch_last_modified() HEAD-requests upstream to discover publish date
- Docker proxy route wires quarantine checks on both cache-hit and cache-miss
- remotes.yaml: quarantine_new/quarantine_days added to pypi example (3-day window)
- README: documents quarantine configuration
Each route in main.py is now a single-line delegation to an artifact submodule:
- artifact/proxy.py — remote artifact GET, caching, mutable revalidation
- artifact/local.py — local repo upload/check/delete
- artifact/docker.py — Docker Registry v2 proxy + ping
- artifact/discovery.py — GitHub release discovery + bulk cache
- artifact/flush.py — cache flush
UpstreamUnreachable, cache_single_artifact, _upstream_reachable and
check_upstream_changed moved from main.py to artifact/proxy.py.
Tests updated to patch at their new locations.
All 187 tests pass.
- npm: remove npm_files_url/npm_files_remote; rewrite uses base_url and
remote name directly (same approach as helm)
- npm: replace hardcoded .tgz extension check with immutable_patterns match
- pypi: collapse pypi + pypi-files into a single remote (base_url points
to files.pythonhosted.org); simple/ requests are transparently fetched
from pypi.org with no extra config required
- pypi: remove pypi_files_url/pypi_files_remote from pypi and pypi-gitea
- pypi: rewrite check now uses immutable_patterns (consistent with npm)
- Update README for both pypi and npm sections
- Update tests and fixtures to reflect single-remote pypi config
- Add helm package type with index.yaml as mutable (TTL-based) and
.tgz chart tarballs as immutable
- Rewrite chart URLs in index.yaml to serve tarballs via proxy cache
- Add text/yaml content-type detection for .yaml/.yml files
- Add hashicorp-helm example remote in remotes.yaml
- Update README with Helm chart repository proxy section
- Add tests for helm mutable patterns and route behaviour
- Add `npm` package type to config with no built-in mutable defaults;
users set explicit mutable_patterns (e.g. ^(?!.*\.tgz$).*) and
immutable_patterns (e.g. \.tgz$) in remotes.yaml
- Rewrite dist.tarball URLs in metadata JSON on the fly so tarball
downloads pass through the same proxy remote instead of hitting
npmjs.org directly
- Single-remote design: npm_files_remote points back to itself since
both metadata and tarballs are served from registry.npmjs.org
- Add .tgz to _get_content_type (application/gzip)
- Add example npm remote to remotes.yaml
- Add npm proxy section to README covering remotes.yaml config,
client setup (npm/yarn/pnpm), rewriting behaviour, and
mutable vs immutable path table
- Add tests for mutable pattern matching, URL rewriting, content-type,
scoped packages, cache miss, and tarball immutability
- Add 'pypi' package type to config.py; simple/ paths are mutable by default
- Refactor content-type detection into _get_content_type() helper; add .whl
- Add _resolve_content() which rewrites files host URLs in simple index HTML
to go through the proxy (pypi_files_url / pypi_files_remote config keys),
and returns text/html content-type for simple index responses
- Add basic auth support for non-Docker remotes (username + password/token
in remote config); thread auth through _upstream_reachable and
check_upstream_changed so mutable TTL checks also authenticate
- Add 'pypi' remote (pypi.org simple index) and 'pypi-files' remote
(files.pythonhosted.org) to remotes.yaml; add 'pypi-gitea' example for
Gitea package registries where index and files share the same base URL
- Add unit tests: simple index URL rewriting, HTML content-type, .whl/.tar.gz
content-types, mutable index detection, and immutable pattern enforcement
When a mutable file's TTL expires and the upstream backend cannot be
contacted (network error or timeout), the cached copy is kept and its
TTL refreshed instead of being evicted. This keeps RPM repodata, Alpine
indexes, branch archives, and other mutable data available during
upstream outages.
Adds UpstreamUnreachable exception and _upstream_reachable() helper.
check_upstream_changed() now raises UpstreamUnreachable on network
errors (was silently returning True). handle_expired_mutable() catches
the exception on the check_mutable_updates path and calls
_upstream_reachable() on the plain-expiry path.
README updated to current immutable/mutable terminology and documents
all new caching features.
Deduplicates the expired-mutable TTL/redownload branching logic that
was copied verbatim between get_artifact and docker_v2_proxy. Adds the
missing happy-path test for a changed mutable file that is successfully
re-fetched from upstream.
When check_mutable_updates: true is set on a remote, expired user-defined
mutable files are revalidated before re-downloading:
- On expiry a conditional HEAD is sent with If-None-Match / If-Modified-Since
- 304 Not Modified: TTL is refreshed in Redis, S3 cache is untouched
- 200 / no conditional support: cache is invalidated and file re-downloaded
- Network error: safe fallback — assume changed, re-download
ETag and Last-Modified from upstream responses are stored in Redis under
mutable:meta:<remote>:<hash> (no expiry, cleaned up on re-download or
cache flush). The flag only applies to user-configured mutable_patterns;
built-in package-type defaults (APKINDEX, repomd.xml, Docker manifests)
are always re-fetched unconditionally.
cache/flush also clears mutable:meta:* keys alongside index:* keys.
Replace the include_patterns/index_patterns split with a clearer
immutable_patterns/mutable_patterns model:
- immutable_patterns: artifacts cached indefinitely (no TTL)
- mutable_patterns: artifacts that expire and are re-fetched after
cache.mutable_ttl seconds (replaces cache.index_ttl)
_PACKAGE_INDEX_PATTERNS renamed to _PACKAGE_MUTABLE_PATTERNS; all
built-in package-type index patterns (APKINDEX, repomd, manifests, etc.)
default to the remote's mutable_ttl (default 1 hour).
cache.file_ttl renamed to cache.immutable_ttl for consistency.
Adds github-archive remote to remotes.yaml as a worked example showing
tag archives as immutable and branch archives as mutable (1-day TTL).
docker-compose.yml: fix VERSION=dev → 2.2.2.dev0 (valid PEP 440),
add :z SELinux label to volume mounts.
