- 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 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.
Remove remotes.yaml from .gitignore and add header comments explaining
the immutable_patterns/mutable_patterns/cache keys. Marks the file
clearly as an example to copy and adapt; warns against committing
real credentials.
