Make libnixrust a dynamic library This is a hack to fix the build on macOS, which was failing because libnixrust.a contains compiler builtins that clash with libclang_rt.osx.a. There's probably a better solution... https://hydra.nixos.org/build/107473280

Only link with libdl on Linux Linux is (as far as I know) the only mainstream operating system that requires linking with libdl for dlopen. On BSD, libdl doesn't exist, so on non-FreeBSD BSDs linking will currently fail. On macOS, it's apparently just a symlink to libSystem (macOS libc), presumably present for compatibility with things that assume Linux. So the right thing to do here is to only add -ldl on Linux, not to add it for everything that isn't FreeBSD.

Add base32 encoder/decoder
2019-09-16 22:18:17 +00:00
Make the Store API more type-safe 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).
