Introducing mkRustCrate #24991

P-E-Meunier · 2017-04-18T09:45:09Z

Motivation for this change

mkRustCrate is an alternative to Cargo for building Rust crates. It is especially useful when using NixOps, as an increasing number of web services (proxies, HTTP(S) servers, SSH servers…) are using Rust, and NixOps recompiles the world on each deployment.

My own current usage of this is with a companion tool called generate-nix-expr, which generates a Nix expression calling out mkRustCrate to keep build products between builds.

This does not replace the version and features resolution algorithm in Cargo, and hence does not yet allow build products to be cached in channels, but that is clearly a foreseeable future of this project.

The maturity level is alpha. I use it successfully to compile and deploy nest.pijul.com, which depends on more than 120 crates, including some that are non-trivial to compile, such as *ring*.

Things done

Tested using sandboxing
(nix.useSandbox on NixOS,
or option build-use-sandbox in nix.conf
on non-NixOS)
Built on platform(s)
- NixOS
- macOS
- Linux
Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
Tested execution of all binary files (usually in ./result/bin/)
Fits CONTRIBUTING.md.

This sounds interesting. Can you also add one or two examples? Also the tool you mentioned generate-nix-expr would be helpful.

P-E-Meunier · 2017-04-18T10:17:07Z

I just uploaded the generate-nix-pkg tool to crates.io: https://crates.io/crates/generate-nix-pkg

Here is an example hello, world (on this particular example, there is no difference with compiling with cargo):

cargo new hello
cd hello
echo "fn main() { println!(\"Hello, world\") }" > src/main.rs

Then, start a new file, hello,nix, in the same directory:

with import <nixpkgs> {};
rec {
  hello = (mkRustCrate {
    crateName = "hello";
    version = "0.1.0";
    src = ./.;
  }) pkgs.rustc;
}

Call nix-build hello.nix, and voilà! No Cargo involved, the compilation is done purely in Nix. The goal is not to replace cargo, though, just to allow projects using the same crates to share compilation products, and avoid recompiling hundreds of packages when deploying web services with nixops.

@P-E-Meunier I suppose the source of this tool is hosted with pijul?

P-E-Meunier · 2017-04-18T11:37:34Z

Sure, why?

Mic92 · 2017-04-18T11:40:54Z

In case I want to contribute changes back. For instances VCS support is a major pain point of the current buildRustPackage function

P-E-Meunier · 2017-04-18T12:20:47Z

In case you want to contribute, the repository is hosted on https://nest.pijul.com/pmeunier/nix-rust.

You are more than welcome to contribute! Feel free to ask anything about Pijul/the Nest/…

Contributing should be way easier than on any other platform, with the minor caveat that not all kinds of SSH keys are supported: unprotected Ed25519 keys work well, unprotected RSA should be fine, protected/agents are not yet supported.

Also, if you write patches, Pijul guarantees that they won't be merged in random places you've never seen, contrarily to what other tools (git/mercurial/svn) do.

Mic92 · 2017-04-18T13:36:25Z

It is called nix-rust, now the confusion is complete: https://github.com/nix-rust/nix :)

FlorentBecker · 2017-04-20T08:46:16Z

What / how many crates did you manage to build with it? Would you say it's ready to be used by nixpkgs itself, or is it too early?

P-E-Meunier · 2017-04-20T09:52:12Z

Here's the build file I use for nest.pijul.com, all the crates build correctly. A huge improvement is that I don't have to keep my unpublished dependencies in the same repository, and I can share them with other projects (such as libpijul).

I don't know whether it could be used by nixpkgs, but the purpose of this pull request is to decide that, and to fill the gaps. There are several caveats:

Nix files are generated from Cargo.lock.
Some features require manual tweaking: cargo build --verbose seems to take the union of all features. I've submitted a bug report asking for Cargo.lock to contain the features, because cargo doesn't always follow its own documentation on the syntax of Cargo.toml.
Platforms complicate the story even more: my compiler doesn't always generate the correct file when the Cargo.toml contains platform-specific things.

The file below is generated automatically, edited to remove references to redox, and called with:

let rust = (pkgs.callPackage ./rust-nightly.nix { }).rust {};
    nest = (import ./nest.nix).nest_0_1_0 rust;
in

Where ./rust-nightly.nix contains a rustup-based derivation to get Rust nightly.

Code

with import <nixpkgs> {};
let release = true;

@P-E-Meunier I suggest you wrap the very long code block in the <details> tag (the syntax of which is like this: https://bpaste.net/show/b70fed4cf128).

P-E-Meunier · 2017-05-05T20:29:36Z

Done.

FlorentBecker · 2017-05-31T20:31:28Z

That's very cool! I think it would be more in line with the rest of nixpkgs and more usable in that context (as opposed to outside the nixpkgs tree) if, instead of using

crates = rec {
   foo_0_1_0 = {
      dependencies = [ bar_0_2 baz_0_1_0];
      …
   };

   bar_0_2 = {…};
   baz_0_1_0 = {…};
}

each crate was defined as a function of its dependencies, and then the knot was tied later:

let foo_0_1_0_ = {bar, baz}:
    { dependencies = [bar baz];
      …
    };

    bar_0_2_ = {…}: {…};
    baz_0_1_0_ = …;
in
rec {
    foo_0_1_0 = foo_0_1_0_ {bar = bar_0_2; baz = baz_0_1_0};
    bar_0_2 = bar_0_2_ {…};
}

This would allow to have several version of the same crate with different dependencies, which is necessary when building stuff from more than one Cargo.lock. If the foo_0_1_0_ functions are defined in separate .nix files, then callPackage can make the "linking" part less painful, there's probably a way with a let … in … too, but I don't know how.

I think the way forward is to convert the packages that can be built with it to mkRustCrate, and keep buildRustPackages if some packages do need the more advanced features of cargo.

P-E-Meunier · 2017-06-01T06:16:19Z

This could certainly be done. How would it look like in your example if foo_0_1_0 depended on several versions of bar?

FlorentBecker · 2017-06-01T07:06:54Z

I'm not sure I understand your question (I think cargo avoids having indirect dependencies with different versions for one crate), but here is an example of how it eliminates duplication in the case where we are introducing derivations for two different crates, foo and toto. The Cargo.lock files of foo and toto look like this:

foo 0.1.0 ---dep---> bar 0.2 ---dep---> baz 0.2
toto 0.1.0 ---dep---> titi 0.3 ---dep---> baz 0.1
toto 0.1.0 ---dep---> bar 0.2 ---dep---> baz 0.1

This is typically the case if titi depends on baz 0.1 and all other dependencies are '*' and get resolved to the latest version.

Then you would have:

let
  foo_0_1_0_ = {bar}: {…; dependencies = [ bar ]; …};
  toto_0_1_0_ = {titi, bar}: {…; dependencies = [ titi bar ]; …};
  let bar_0_2_ = {baz}: {…; dependencies = [ baz ];…};
  let baz_0_1 = {…};
  let baz_0_2 = {…};
in
rec {
   foo_0_1_0 = foo_0_1_0_ { bar = bar_0_2 };
   toto_0_1_0 = toto_0_1_0_ { bar = bar_0_2_ {baz = baz_0_1} };
   bar_0_2 = bar_0_2_ { baz = baz_0_2 };
   inherit baz_0_1 baz_0_2;
}

Again, the function calls in the 'rec {}' can be made less verbose through callPackage.

Note that this does not bring anything from the point of view of nix avoiding recompilations (your solution is already as good as possible from that point of view), it just makes the code cleaner for a collection of packages.

I don't think this belongs in this PR. I wonder where it's coming from 😋

FlorentBecker · 2017-06-01T09:06:03Z

65009f2 should probably be rebased out of this PR

P-E-Meunier · 2017-06-02T09:39:11Z

Cargo "does its best to avoid different version of the same indirect dependency", but cannot always avoid it.

Your comment answers my question I guess. I'll try to implement that soon.

FlorentBecker · 2017-06-26T08:57:39Z

Any news about the "let … in rec {…}" solution? I'm eager to try and port at least some rust packages to mkRustCrate, but I don't want to short-cut something you're doing.

P-E-Meunier · 2017-06-26T14:20:26Z

I'm not working on it right now, but it's definitely on my todo-list.

P-E-Meunier · 2017-08-11T13:46:00Z

Hi! Look at the new output format of the script that produces nix files. The source of everything is still at the same place:

https://nest.pijul.com/pmeunier/nix-rust

I agree that crates from crates.io can now be packaged into nix.
Something needs to be written to maintain an updated version of all packages on crates.io. Maybe in an overlay, to avoid automatic commits?

It would be very convenient if 2 things happened to generate-nix-pkg (via cli argument or not)

The top line of the generated output is this: with import <nixpkgs> {}; it would be better if it was: { mkRustCrate fetchzip }:
This allows the generated output to be used without including the whole nixpkgs, most likely the generated code would be used as part of a larger project so <nixpkgs> will be included elsewhere. Also I'll be making changes to mkRustCrate so this way I can select exactly which mkRustCrate is pulled in.
For every crate derivation an indirection is introduced, for example include a line libc = libc_0_2_29 {}; where libc always points to the latest libc_x_x_x derivation in the generated set.
This allows projects to say they want to always have the latest crate derivation, which localizes maintenance to just generating the nix output and running a test to see that things still build/work.
In the case the latest crate derivation doesn't work one can default to an explicitly versioned crate derivation.

my 2c worth.

Really love this work, kudos!

sjmackenzie · 2017-08-31T06:57:33Z

Also one dirty hack I'm exploring is making only one generate-nix-pkg generation for every rust project that needs a subset of crate derivations.

The master toml file would look something like this:

[lib]

[package]
name = "all_crates"
version = "0.0.0"

[dependencies]
capnp = "*"
nom = "*"
iron = "*"
mount = "*"
staticfile= "*"
# add more crates as needed

The above is the minimal needed information in order to run cargo generate-lockfile.

This allows users to pull in the latest crate derivations where needed (in combination with the above xxx = xxx_y_y_y {}; indirection feature).

One downside to this approach is that you cannot include duplicate crate names in a Cargo.toml file. So:

capnp = "*"
capnp = "0.8.10"
capnp = "0.8.9"

will not work.

For anyone who might want those feature requests which could help integrating this into nixpkgs easier here you go: https://nest.pijul.com/sjmackenzie/nix-rust

@sjmackenzie the link you just posted seems to be broken.

sjmackenzie · 2017-09-06T08:53:36Z

@vitiral there was a problem with nest.pijul.com @P-E-Meunier has resolved it. See my amended comment above.

sjmackenzie · 2017-09-13T09:44:25Z

@P-E-Meunier is there an associated change for generate-nix-pkg rust code? It would seem you've managed to run an executable that has a crate with build-dependencies. I'm probably getting similar issues as your backtrace-sys crate when running a binary that has the libsqlite3-sys crate.

namely:

thread '<unnamed>' panicked at 'cannot load: Error { repr: Custom(Custom { kind: Other, error: StringError("/nix/store/r471jgziyzl63sjmw3ghps1610isg0ya-rs_sqlite_get/lib/libagent.so: undefined symbol: sqlite3_bind_int64") }) }', /checkout/src/libcore/result.rs:906:4

We can now compile OpenSSL!

sjmackenzie · 2017-10-29T10:48:15Z

Nice one! Look forward to trying this out.

P-E-Meunier · 2017-11-02T10:06:05Z

Can I do anything more to get this PR to be merged?

sjmackenzie · 2017-11-02T13:15:51Z

@peti @qknight

qknight · 2017-11-02T19:42:08Z

@sjmackenzie the patch conflicts, needs fix from you before we can merge. also please provide a way we can test this PR. or document how it can be used.

P-E-Meunier · 2017-11-02T20:10:06Z

That's assuming I know enough Git and GitHub to get my old branch back (I've deleted the repository where I produced it a while ago).

So, I've added the latest version as #31150. It can compile everything I've needed so far, including tricky crates such as *ring* and (since recently) OpenSSL.

qknight · 2017-11-02T20:35:16Z

@P-E-Meunier i'm confused, don't you want that code in nixpkgs?

sjmackenzie · 2017-11-02T20:40:18Z

Na mate, he deleted his old branch and being sufficiently unfamiliarity with git and github (he's the author of pijul that's his lingua franca :-) ). So he decided to start on a fresh branch #31150 (adding docs etc). That's the code that'll merge into nixpkgs.

P-E-Meunier · 2017-11-02T20:40:31Z

I do want that code in nixpkgs, but this branch was several months old and I've been adding lots of custom stuff to my nixpkgs, so that I couldn't fix the conflict. However, the exact same code is in #31150, it has no conflicts with the current nixpkgs. Maybe this time it will make it ;-)
