2022-11-16	Replace src/libutil/json.cc with nlohmann json generation	Yorick van Pelt

2022-01-18	Get rid of std::shared_ptr<std::string> and ref<std::string>	Eelco Dolstra
	These were needed back in the pre-C++11 era because we didn't have move semantics. But now we do.
2020-07-13	NarAccessor: Run in constant memory	Eelco Dolstra

2017-12-16	Fix build on gcc 7	Eelco Dolstra
	Fixes #1738.
2017-12-07	Provide random access to cached NARs	Eelco Dolstra
	E.g. $ time nix cat-store --store https://cache.nixos.org?local-nar-cache=/tmp/nars \ /nix/store/b0w2hafndl09h64fhb86kw6bmhbmnpm1-blender-2.79/share/icons/hicolor/scalable/apps/blender.svg > /dev/null real 0m4.139s $ time nix cat-store --store https://cache.nixos.org?local-nar-cache=/tmp/nars \ /nix/store/b0w2hafndl09h64fhb86kw6bmhbmnpm1-blender-2.79/share/icons/hicolor/scalable/apps/blender.svg > /dev/null real 0m0.024s (Before, the second call took ~0.220s.) This will use a NAR listing in /tmp/nars/b0w2hafndl09h64fhb86kw6bmhbmnpm1.ls containing all metadata, including the offsets of regular files inside the NAR. Thus, we don't need to read the entire NAR. (We do read the entire listing, but that's generally pretty small. We could use a SQLite DB by borrowing some more code from nixos-channel-scripts/file-cache.hh.) This is primarily useful when Hydra is serving files from an S3 binary cache, in particular when you have giant NARs. E.g. we had some 12 GiB NARs, so accessing individuals files was pretty slow.
2017-11-14	nix ls-{nar,store} --json: Respect -R	Eelco Dolstra

2017-11-14	nix ls-{store,nar}: Add --json flag	Eelco Dolstra

2016-02-25	Add NAR / Store accessor abstraction	Eelco Dolstra
	This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
