Describe Bug

When using xmake with the Rust language, there seem to be a problem with the way it handles Cargo packages.

I have the following requires:

add_requires("cargo::cxx", 
    "cargo::actix-web 4.0",
    "cargo::env_logger 0.9",
    "cargo::log 0.4",
    "cargo::twitch-irc 4.0")
add_requires("cargo::tokio 1.17", { configs = { features = {"rt-multi-thread", "macros", "time"}}})

and the following target:

target("WebService")
    set_kind("static")
    add_files("src/Nazatwitch/WebService/**.rs")
    add_packages("cargo::actix-web", "cargo::env_logger")
    add_packages("cargo::cxx")
    add_packages("cargo::tokio")
    add_packages("cargo::twitch-irc")
    set_values("rust.cratetype", "staticlib")
    if is_plat("windows", "mingw") then
        add_syslinks("bcrypt", "Crypt32", "Ncrypt", "NtDll", "Secur32", "ws2_32", "Userenv", { public = true })
    end

(syslinks are required for Rust features but that's another issue)

xmake installs those packages without issue, but when I use them, they don't work quite right.

The issue is that xmake handle every cargo package separately, which means that actix-web, twitch-irc and tokio are three separate libs, and there is in fact 3 times tokio (as it's a dep of actix-web and twitch-irc).

Since tokio relies on global variables, it can lead to this famous Rust error:

thread '<unnamed>' panicked at 'there is no reactor running, must be called from the context of a Tokio 1.x runtimeInitializing Platform...',
C:\Users\lynix\.cargo\registry\src\github.com-1ecc6299db9ec823\twitch-irc-4.0.0\src\client\event_loop.rs:84:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

which happens when you have multiple Tokio runtimes (which happens when you have different tokio versions).

I did try the very same Rust file with this Cargo.toml:

[package]
name = "test_actix_twitchirc"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
actix-web = "4.0"
env_logger = "0.9"
log = "0.4"
twitch-irc = "4.0"
tokio = { version = "1", features = ["rt-multi-thread", "macros", "time"] }

which worked.

I see two possibles fixes here:

1. That xmake collects all Cargo dependencies to build one single Cargo.toml to allow it to merge dependencies and collect the result, this is the easiest fix I think.
2. That xmake collects every cargo package dependency (actix-web => tokio and more), like it does for C++ packages, and install it separately (and allows it to reuse them). But it means to have a lot of dependencies in the list. XMake should also merge packages by features.

Expected Behavior

That xmake manages to reuse tokio and other rust dependencies to have a working program.

With cargo, it works:

The issue is that xmake handle every cargo package separately, which means that actix-web, twitch-irc and tokio are three separate libs, and there is in fact 3 times tokio (as it's a dep of actix-web and twitch-irc).

But xmake just add three libs. like adding links actix_web tokio twitch_irc

actix_web.dylib will contains tokio codes?

Yes but as static libraries, each of them will embed the code for tokio.

It is only a static lib. Can you provide a whole test example project?

Sure, it's just taking that Rust file and compiling it with Cargo and with xmake, I can make you a quick example soon.

(note that you need xmake dev for this)

[waruqi]

That xmake collects all Cargo dependencies to build one single Cargo.toml to allow it to merge dependencies and collect the result, this is the easiest fix I think.

This solution is also not very well implemented. Each add_requires uniquely corresponds to a package instance for parallel installation. Even if combined into a single cargo.toml, several different cargo.toml may be required if different targets require different dependency groups.

We need to improve the add_requires interface to support the description of all cargo deps in a single add_requires.

Solution1

Use Cargo.toml

add_requires("cargo::test_actix_twitchirc", {configs = {tomlfile = path.join(os.scriptdir(), "Cargo.toml")}})

Cargo.toml

[package]
name = "test_actix_twitchirc"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
actix-web = "4.0"
env_logger = "0.9"
log = "0.4"
twitch-irc = "4.0"
tokio = { version = "1", features = ["rt-multi-thread", "macros", "time"] }

Solution2

Write cargo.toml configuarion in xmake.lua

add_requires("cargo::test_actix_twitchirc", {configs = {dependencies = [[
    actix-web = "4.0"
    env_logger = "0.9"
    log = "0.4"
    twitch-irc = "4.0"
    tokio = { version = "1", features = ["rt-multi-thread", "macros", "time"] }
]]}})

Both solutions can also be supported and are compatible with the current single add_requires("cargo::actix-web 4.0") configuration.

If we only use a single rust package, we can still continue to use add_requires("cargo::actix-web 4.0")

Both solutions are great but I think the first one is the best because Cargo.toml are part of the Rust ecosystem and may be needed by other tools such as Visual Studio Code for auto-completion.

I have supported the solution1, and tested it for your example. It works now. #2235

add_rules("mode.release", "mode.debug")
add_requires("cargo::test", {configs = {cargo_toml = path.join(os.projectdir(), "Cargo.toml")}})

target("test")
    set_kind("binary")
    add_files("src/main.rs")
    add_packages("cargo::test")

Does it work?

[SirLynix]

Sorry I couldn't test until today.

Yes it works well, thank you. However it's not taking Cargo.toml updates into account, could it be possible to automatically handle this, or should I use version number for package?

Thanks a lot.

you need add version to add_requires("cargo::test 1.0")
