2020-03-24Flip dependency so store-api.hh includes derivations.hhJohn Ericson
I think it makes more sense to define the data model (derivations), before the operations (store api).
2019-12-10Make the Store API more type-safeEelco 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).

A partner of builtins.getContext, useful for the same reasons.

This can be very helpful when debugging, as well as enabling complex black magic like surgically removing a single dependency from a string's context.
