2021-07-22copyPaths: Pass store by referenceEelco Dolstra
2021-07-22nix-build: Copy drv closure between eval store and build storeEelco Dolstra
2021-02-25Use `RealisedPath`s in `copyPaths`regnat
That way we can copy the realisations too (in addition to the store paths themselves)
2021-02-24Initialize plugins after handling initial command line flagsShea Levy
This is technically a breaking change, since attempting to set plugin files after the first non-flag argument will now throw an error. This is acceptable given the relative lack of stability in a plugin interface and the need to tie the knot somewhere once plugins can actually define new subcommands.

2020-10-06Remove static variable name clashesEelco Dolstra
This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...

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).
2018-10-26Merge all nix-* binaries into nixEelco Dolstra
These are all symlinks to 'nix' now, reducing the installed size by about ~1.7 MiB.
2018-04-21Fix library ordering in MakefilesAndrew Dunham
The existing ordering linked `libutil` before `libstore`, which causes link failures when building statically. This is due to `libstore` using functions from `libutil`, and the fact that symbol resolution works "forward" - i.e. if you pass `-lfoo -lbar -lbaz`, any symbols that `libbar` uses from `libbaz` will be resolved, but symbols from `libfoo` will not since it comes first in the command line. All this to say: this commit reorders the libraries which fixes the link errors.
2018-02-08Add plugins to make Nix more extensible.Shea Levy
All plugins in plugin-files will be dlopened, allowing them to statically construct instances of the various Register* types Nix supports.

2017-07-03Replace a few bool flags with enumsEelco Dolstra
Functions like copyClosure() had 3 bool arguments, which creates a severe risk of mixing up arguments. Also, implement copyClosure() using copyPaths().

This restores the old behaviour.
