CI, the release binaries and swagger take their Go version from go.mod,
which pinned 1.26.7 and so missed the stdlib fixes in 1.26.8 to 1.26.10.
A toolchain line now sets 1.27.3 for them, and the Docker builder uses
the same version. The go line stays at 1.26.7, so source builds with an
older local Go still work.
golangci-lint 2.13.1 can't read Go 1.27.2+ export data, so CI moves to
2.15.0. Its errcheck flags two test cleanups that dropped the server's
exit error; they now check it.
Composer names are case-insensitive, so acme/private and acme/Private
share the version record and its integrity but get different filenames.
A second push under the other case was accepted and broke the integrity
check of the first archive. For ecosystems with one file per version,
any pushed file of the version now refuses the push, both before the
upload and atomically when recording it.
- Record a fetched artifact with its package and version in one
transaction that refuses to replace a pushed artifact, so a fetch that
finishes after a push keeps both the pushed file and its version's
integrity. Pushes and cache fills share this write, including the
compare-and-swap on the storage path that queues every replaced object.
- Don't open the stored file for ecosystems without a manifest.
- Derive multi-file versions from the file being named in the path.
- Validate DELETE paths like PUT paths, answering 400 for malformed ones.
- Parse ?sha256= with integrity.ParseHex.
- Record the package, version and artifact of a push in one transaction
that only inserts the artifact if no pushed copy exists. Of two
concurrent pushes of the same file exactly one wins, and the loser's
version integrity is rolled back with it.
- Check for an existing file before reading the request body, and send
Expect: 100-continue from proxy hosted push, so a refused re-push isn't
uploaded first.
- Leave an existing version record alone for multi-file ecosystems, so a
generic push doesn't reset a version cached from upstream.generic.
- Reserve the upstream.generic name "hosted" only while hosting is
enabled, and only intercept /generic/hosted/ then.
- Accept a file argument in proxy hosted delete for generic only.
- Mark multi-file ecosystems explicitly, and give parse a min/max range.
Hosted ecosystems are now entries in one table: each defines its package
names, how the stored filename is chosen, how the manifest is read and which
namespaces are served from pushes alone. npm and Composer move there
unchanged, and generic is added as a third entry.
Generic files are pushed to /api/hosted/generic/{name}/{version}/{file}
and served without a token from /generic/hosted/{name}/{version}/{file},
with the sha256 as ETag. They have no manifest, a version can hold several
files, and they never come from an upstream. "hosted" is reserved as an
upstream.generic name. DELETE with a file removes only that file.
For all hosted ecosystems:
- A second push of the same file is refused with 409. Clients pin pushed
files by version and often by hash, so a published file is no longer
silently replaced. Delete it first to push it again.
- PUT takes an optional ?sha256= and refuses bytes that don't match.
proxy hosted push always sends it.
Versions of generic files carry no version-level integrity, since it could
only describe one of their files; each file is checked against its own
sha256.

With hosted packages enabled, a package's p2 metadata lists its pushed versions, built from composer.json without the root-only keys, with a zip dist at the proxy and the time they were pushed. dist.reference is the archive's sha256 so a re-push isn't served from Composer's cache, and shasum is left empty. Dev versions go to the ~dev file and tagged versions to the other.
A pushed version takes the place of an upstream entry with the same version, with or without a leading v. Pushed entries follow the upstream ones and go through the same minified writer, so fields an earlier upstream entry set and the pushed one lacks are written as __unset rather than inherited.
When the upstream doesn't know the package, the document holds only the pushed versions. Like npm, documents with pushed versions bypass the rewrite cache.
Refs #134
With hosted packages enabled, the packument of a package with pushed versions lists each of them, built from its package.json with dist pointing at the proxy and carrying the archive's sha512, and the time it was pushed. A pushed version takes the place of an upstream entry with the same version. Cooldown and the denylist still filter only upstream versions, and dist-tags stay as upstream has them.
When the upstream doesn't know the package, the packument holds only the pushed versions, with latest set to the highest of them. Requests for a single pushed version are answered from its entry.
Rewrites that include pushed versions bypass the rewrite cache, which is keyed by the upstream document alone, so a push or delete shows on the next request and changes the ETag. Packages without pushed versions take the cached path as before, and with hosted packages disabled there is no extra lookup.
Refs #134
Resolvers take a version's dependencies from the registry metadata, not from the archive, so listing a pushed version needs its manifest. A push now reads package.json from the top directory of an npm tarball, or composer.json from the root or the single top directory of a Composer zip, and keeps it in the new artifacts.manifest column (migration 013_add_artifact_manifest).
The manifest has to name the pushed package and version. A Composer manifest may leave the version out, and its name is compared case-insensitively. An archive that can't be read or whose manifest names something else is refused with 400 and removed from storage.
The version's integrity is now the archive's sha512, which npm clients expect in dist.integrity.
Refs #134
With hosted.enabled, PUT /api/hosted/{ecosystem}/{name}/{version} stores the request body as the archive for that version, marked local. It replaces any cached upstream copy and is served from the cache without contacting the upstream. GET /api/hosted/{ecosystem}/{name} lists what was pushed and DELETE removes a version again, after which clients get the upstream archive if there is one. Pushing and deleting need the bearer token; listing is open like the rest of the API.
Download handlers look archives up by the filename clients request, so a push is stored under the name its ecosystem derives from name and version: {name}-{version}.tgz for npm, without the scope, and {package}-{version}.zip for Composer. Other ecosystems are refused for now.
The Composer download handler resolves the upstream metadata before it looks at the cache and answers 404 for versions the upstream doesn't list. It now serves a pushed archive first. Only artifacts marked local take that path, so cached upstream archives still go through the metadata and commit checks.
The version's integrity is set to the pushed bytes, so the cache's integrity check verifies them rather than an upstream digest. Names and versions with path separators, dot segments or control characters are refused before anything is stored.
