There are separate derivations for these libraries and we don't want
conflict. Multitarget is generally more useful, and will eventually
speed up cross builds, so why not?!
On most distros, these are just built and distributed as part of
binutils. We don't use binutils across the board, however, but rather
switch between binutils and a cctools-binutils mashup, and change the
outputs on binutils too. This creates a combinatorial conditional soup
which is hard to maintain.
My hope is to lower the the state space. While my patch isn't the most
maintainable, they make downstream packages become more maintainable to
compensate. The additional derivations themselves are completely
platform-agnostic, always they always supports all possible target
platforms, and always yield "out" and "dev" outputs. That, in turn,
allows downstream packages to not worry about a dependency
shape-shifting under them.
In fact, the actual binutils package can avoid needing multiple outputs
now that these serve the requisite libraries, so that also can become
simpler on all platforms, too, removing the original wart this PR
circumnavigates for now. Actually changing the binutils package to
leverage is a mass rebuild, however, so I'll leave that for a separate
PR.
I do hope to upstream something like my patch too, but until then I'll
make myself maintainer of these derivations
The biggest benefit is that we no longer have to update the registry
package. This means that just about any cargo package can be built by
nix. No longer does `cargo update` need to be feared because it will
update to packages newer then what is available in nixpkgs.
Instead of fetching the cargo registry this bundles all the source code
into a "vendor/" folder.
This also uses the new --frozen and --locked flags which is nice.
Currently cargo-vendor only provides binaries for Linux and
macOS 64-bit. This can be solved by building it for the other
architectures and uploading it somewhere (like the NixOS cache).
This also has the downside that it requires a change to everyone's deps
hash. And if the old one is used because it was cached it will fail to
build as it will attempt to use the old version. For this reason the
attribute has been renamed to `cargoSha256`.
