daemon: Bypass authentication when importing content-addressed store items.

2026-08-17T14:47:36+00:00

This puts ‘importPaths’ on par with ‘addToStore’ and ‘addTextToStore’: since
the two latter RPCs let anyone add content-addressed items in the store,
there’s no reason for ‘importPaths’ to require signatures by authorized keys
on these content-addressed items.

This will allow for things like ‘guix copy’ of .drv items without
authorization, or ‘guix deploy’ with (build-locally? #f) without
authorization.

* nix/libstore/store-api.hh (isContentAddressedPath): New prototype.
* nix/libstore/store-api.cc (isContentAddressedPath): New function.
* nix/libutil/util.hh (isPlainFile): New prototype.
* nix/libutil/util.cc (isPlainFile): New function.
* nix/libstore/local-store.cc (LocalStore::importPath): Define ‘narHash’ and
‘contentAddressed’.  Allow unsigned imports when ‘contentAddressed’ is true;
bypass signature verification when ‘contentAddressed’ is true.
* tests/store.scm ("import not signed"): Rewrite to not use a
content-addressed store item.
("import signed by unauthorized key"): Likewise.
("import not signed but content-addressed tree"): New test.
("import not signed but content-addressed regular file"): New test.
("import signed by unauthorized key but content-addressed"): New test.
("import with corrupt signature"): New test.
("import signed by authorized key but hash doesn't match"): New test.
("import with corrupt signature but content-addressed"): New test.
("import signed by authorized key, hash doesn't match, but content-addressed"):
New test.
* doc/guix.texi (Invoking guix archive): Document the exception for
content-addressed store items.  Add anchor for ‘--authorize’.
(Invoking guix deploy): Document the benefit of (build-locally? #f).
Add cross-reference for ‘authorize?’.
