Rust build possibly running out of RAM

[Benji377]

Intro

I am creating a Tauri app. It has a frontend in Next.js and the backend in Rust. Using the Tauri command with cargo, I can build the project for different platforms like Ubuntu, Windows and Mac. Unfortunately, I am not able to compile the project for the Raspberry Pi because it has a different chip architecture. Therefore, I wanted to use your runner to try and build it using GitHub actions.

Problem

When I execute the GitHub action, everything seems to work fine, up until it tries to install tauri with the cargo command: cargo install tauri-cli. Then it starts compiling the needed dependencies and eventually fails because it doesn't have enough RAM to continue. It doesn't say that it doesn't have enough RAM, but when I tried to install tauri on my Raspberry Pi 3B+ with 1 GB of RAM, I encountered the same error. I solved it by increasing swap to 4 GB.

Well, never mind, I just run the free -m command in the Runner, and it does have about 7 GB of RAM. That's more than the Raspberry I used with SWAP.

               total        used        free      shared  buff/cache   available
Mem:            6943         617         205          22        6121        6010
Swap:           4095           0        4095

I really don't know what the issue could be now

@Benji377 It might be due to the disk space. By default, it is about 24GB available, see #75

[Benji377]

I executed df -h just before the runner exits to check the size and here is the output:

 + df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/loop3p2     11G  4.1G  6.0G  41% /
/dev/loop3p1    127M   32M   96M  26% /boot
devtmpfs        3.4G     0  3.4G   0% /dev
+ cargo install tauri-cli

After I execute the cargo install tauri-cli command, the Runner exits.
@razr Maybe it has to do with disk space, but how do I increase it?

[razr]

I'm doing it like this for the GH runner:

    - name: Increase free space
      # Remove Android and dotnet
      run: |
        df -h
        sudo rm -rf /usr/local/lib/android
        sudo rm -rf /usr/share/dotnet
        df -h

I see that you set image_additional_mb: 10240. Maybe it should be more?

[Benji377]

Unfortunately, even when doubling the size, I get the same error

[pguyot]

This seems to be related:
rust-lang/rust#64248 (comment)

But the workaround (cleaning up registry), didn't work unfortunately.

[Benji377]

What you are saying is that this issue is more likely related to Rust not being able to download some crates, right?

[pguyot]

The issue is Rust related. It's not that it cannot download crates but rather that it cannot download the index.
I did find a workaround and created a PR on your repo. It's still running but past the installation of taurus-cli.

See https://github.com/pguyot/Raspirus/actions/runs/5039610464/jobs/9037866452
