2023-05-24	Make `RewritingSink` accept a map of rewrites	Théophane Hufschmitt
	Giving it the same semantics as `rewriteStrings`. Also add some tests for it
2023-03-31	Ensure all headers have `#pragma once` and are in API docs	John Ericson
	`///@file` makes them show up in the internal API dos. A tiny few were missing `#pragma once`.
2022-11-11	Restrict `readFile` context to references that appear in the string	Naïm Favier
	When calling `builtins.readFile` on a store path, the references of that path are currently added to the resulting string's context. This change makes those references the possible context of the string, but filters them to keep only the references whose hash actually appears in the string, similarly to what is done for determining the runtime references of a path.
2021-10-04	Add a test for RefScanSink and clean up the code	Eelco Dolstra
	Issue #5322.

2019-10-21	Allow content-addressable paths to have references	Eelco 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
2012-07-18	Use "#pragma once" to prevent repeated header file inclusion	Eelco Dolstra

2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2009-03-28	* Scan for references and compute the SHA-256 hash of the output in	Eelco Dolstra
	one pass. This halves the amount of I/O.
2006-09-04	* Use a proper namespace.	Eelco Dolstra
	* Optimise header file usage a bit. * Compile the parser as C++.
2005-11-16	* Did something useful while waiting at IAD: reference scanning is now	Eelco Dolstra
	much faster.
2003-11-18	* libnix -> libstore.	Eelco Dolstra
