100% CPU consumption bug

[dizda]

Describe the bug

When I launch the "helloworld" example, the CPU consumption goes to 100%.
The commit 3280c4a introduce the bug.

To Reproduce

git checkout 3280c4aa91e50a8ccdd561a8b48a12a4a13ea8d5
cd examples/helloworld
cargo tauri dev

Expected behavior

CPU Should be around 0% when idling.
Previous commit (f7d21a4) doesn't have this bug.

git checkout f7d21a4b864e067856018e7b1f4ba178aea46d71
cd examples/helloworld
cargo tauri dev

I've also noticed that the mapping of commands between rust and the JS doesn't work.

[nothingismagick]

That is because you are using the old version of tauri core.

tauri.rs - path:"../../../core/tauri" [1.0.0-beta.1] (no lockfile)

Please either update the source or use the latest crate from crates.io

[nothingismagick]

Because its a bit confusing, I went and tried it, running directly on m1 mac from dev (both via yarn tauri and cargo tauri), without any problems - but you should remember a couple things:

1. please try to use latest toolchains - i.e. what is your version of the rust tauri-cli (cargo tauri --version)
2. try this: cargo install tauri-cli --version ^1.0.0-beta.2 / or force install from the proper folder /tooling/cli.rs
3. or run the JS version (check out the pathing in that example's package.json

[dizda]

FYI, I'm also on m1 mac.

what is your version of the rust tauri-cli

❯ cargo tauri --version
cargo-tauri 1.0.0-beta.2

tauri.rs - path:"../../../core/tauri" [1.0.0-beta.1] (no lockfile)

I think this is misinterpreted, because I've cloned the tauri repo, and checked out the right tag (1.0.0-beta.2).
I had first that issue with my own project, and I wanted to make sure the error was not coming from my projected, so I've tested it out with the provided examples from tauri's, and I encountered the same issues.

tauri.rs - path:"../../../core/tauri" [1.0.0-beta.1] (no lockfile)

About that part, it's when I've checked the earliest commit to find out when it started to produce the bug.

Here is the right cargo tauri dev when I check out the latest tag "git checkout tauri-v1.0.0-beta.2" (still with the bug)

active toolchain

1.52.1-aarch64-apple-darwin (overridden by '/Users/j/www/tauri/rust-toolchain')
rustc 1.52.1 (9bc8c42bb 2021-05-09)

[nothingismagick]

I am on the same rustc as a matter of fact - although we should both move to 1.53.0 :|

[dizda]

I've also tried with yarn tauri dev, same result.

I wonder what else could be different from your environment and mine?
Do you get normal CPU consumption?

This is closed but I also have this issue.
Using npx create-tauri-app and picking the vanilla.js version.
If I run it cpu is at 100%.

Hmm. You know, something I remembered is that I actually transferred the contents of my Intel mac to the M1, and I am actually still using the Intel version of rustc: x86_64-apple-darwin - I never bothered to switch over since everything was working fine.

Maybe @wusyong can help us out here, since he also has an m1
