This replaces the copy&paste with a helper function in hash.hh.
2020-06-02Fix hashesJohn Ericson
2020-06-02Remove `HashType::Unknown`John Ericson
Instead, `Hash` uses `std::optional<HashType>`. In the future, we may also make `Hash` itself require a known hash type, encoraging people to use `std::optional<Hash>` instead.
2020-05-10nix: Implement basic bash completionEelco Dolstra
2020-03-29Use `enum struct` and drop prefixesJohn Ericson
This does a few enums; the rest will be gotten in subsequent commits.
2019-10-21Allow content-addressable paths to have referencesEelco Dolstra
This adds a command 'nix make-content-addressable' that rewrites the specified store paths into content-addressable paths. The advantage of such paths is that 1) they can be imported without signatures; 2) they can enable deduplication in cases where derivation changes do not cause output changes (apart from store path hashes). For example, $ nix make-content-addressable -r nixpkgs.cowsay rewrote '/nix/store/g1g31ah55xdia1jdqabv1imf6mcw0nb1-glibc-2.25-49' to '/nix/store/48jfj7bg78a8n4f2nhg269rgw1936vj4-glibc-2.25-49' ... rewrote '/nix/store/qbi6rzpk0bxjw8lw6azn2mc7ynnn455q-cowsay-3.03+dfsg1-16' to '/nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16' We can then copy the resulting closure to another store without signatures: $ nix copy --trusted-public-keys '' ---to ~/my-nix /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 In order to support self-references in content-addressable paths, these paths are hashed "modulo" self-references, meaning that self-references are zeroed out during hashing. Somewhat annoyingly, this means that the NAR hash stored in the Nix database is no longer necessarily equal to the output of "nix hash-path"; for content-addressable paths, you need to pass the --modulo flag: $ nix path-info --json /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 | jq -r .[].narHash sha256:0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 1ggznh07khq0hz6id09pqws3a8q9pn03ya3c03nwck1kwq8rclzs $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 --modulo iq6g2x4q62xp7y7493bibx0qn5w7xz67 0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw
2018-12-13Support SRI hashesEelco Dolstra
SRI hashes (https://www.w3.org/TR/SRI/) combine the hash algorithm and a base-64 hash. This allows more concise and standard hash specifications. For example, instead of import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; sha256 = "5d22dad058d5c800d65a115f919da22938c50dd6ba98c5e3a183172d149840a4"; }; you can write import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; hash = "sha256-XSLa0FjVyADWWhFfkZ2iKTjFDda6mMXjoYMXLRSYQKQ="; }; In fixed-output derivations, the outputHashAlgo is no longer mandatory if outputHash specifies the hash (either as an SRI or in the old "<type>:<hash>" format). 'nix hash-{file,path}' now print hashes in SRI format by default. I also reverted them to use SHA-256 by default because that's what we're using most of the time in Nixpkgs. Suggested by @zimbatm.
