2020-06-16	Remove StorePath::clone() and related functions	Eelco Dolstra

2020-06-16	StorePath: Rewrite in C++	Eelco Dolstra
	On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB and runtime by 0.8%. This is mostly because we're not parsing the hash part as a hash anymore (just validating that it consists of base-32 characters). Also, replace storePathToHash() by StorePath::hashPart().

2020-02-13	Prevent uninitialized StorePath creation	Eelco Dolstra

2019-12-10	Make the Store API more type-safe	Eelco Dolstra
	Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).

2017-09-10	Add command "nix why-depends"	Eelco Dolstra
	This command shows why a package has another package in its runtime closure. For example, to see why VLC has libdrm.dev in its closure: $ nix why-depends nixpkgs.vlc nixpkgs.libdrm.dev /nix/store/g901z9pcj0n5yy5n6ykxk3qm4ina1d6z-vlc-2.2.5.1: lib/libvlccore.so.8.0.0: …nfig:/nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… /nix/store/s3nm7kd8hlcg0facn2q1ff2n7wrwdi2l-mesa-noglu-17.0.7-dev: nix-support/propagated-native-build-inputs: …-dev /nix/store/405lmx6jl8lp0ad1vrr6j498chrqhz8g-libdrm-2.4.75-d… Thus, VLC's lib/libvlccore.so.8.0.0 as well as mesa-noglu's nix-support/propagated-native-build-inputs cause the dependency.
