Upgrading an old configuration to later i3status-rust versions

[Kabouik]

Someone recently updated i3status-rust for Guix, which is great news because we were so far stuck with a 0.20ish version. However, old configurations are not compatible.

I could make a few easy changes after running i3status-rs in the terminal and checking the first errors, but now they are fixed and upon running i3status-rs, my device freezes immediately (I can't even use C-c immediately in the terminal to interrupt) with all my blocks just showing "Configuration error", and the terminal output not showing anything particularly useful (unless there are errors before it dumps my config in the output, but I can't scroll up due to the freeze; might need to try catching all that in a file). The freeze forces a hard reboot, which makes it really hard to troubleshoot and find what more to alter in the configuration.

Is there some kind of hidden dry-run option available? Alternatively, how could I proceed to launch i3status-rs without it freezing the system?

For reference, below is my configuration in case you would see something obvious that may cause the freeze:

[MaxVerevkin]

I cannot reproduce the freeze using your config. For updating the config, I would recommend commenting everything out and updating the config block by block. Most of the breaking changes are listed here.

[Kabouik]

Thank you for the help and for your time testing my config, I failed finding the breaking changes but I didn't look in the release notes. With that, I could at least alter my config to at least show the bar again. It still shows several configuration errors, but it was just a quick first pass, I'll now need to check blocks individually more carefully.

The problem is this did not fix the freezing behavior, which again makes it much harder to debug and fix (especially with every reboot being a tad long due to LUKS encryption).

In the meantime, I'm back to Sway's default bar, but don't quite like it and didn't really configure it so it's missing a lot of information.

So I finally got back to trying to fix my configuration on that computer. All blocks look okay now with the config below, but the system still freezes 2 to 3 seconds after launching i3status-rs, with a rapid fan speed increase suggesting a CPU hog.

[MaxVerevkin]

Can you bisect which block causes this? Or at least bring the configuration to a minimum example: remove all comments, click handlers, theming, and remove blocks one by one while the issue is still there.

PS: You can write

```toml
<your toml here>
```

to make the config nice to read. This also adds a "copy" button, which is pretty useful.

[ammgws]

Maybe first try removing all custom blocks, and see if the issue persists with the 'native' i3status-rs blocks.

[Kabouik]

Thanks for the replies. Sorry I'm not replying fast, I'm currently away without that computer.

Yeah I did post code as toml before but this time just wanted to collapse it to avoid cluttering the issue, but now I realized it messed the syntax up so I edited.

You were both right, the issue was with the custom blocks, in particular the ryzenadj ones. Turns out ryzenadj
is supposed to be whitelisted in my /etc/sudoers file but it doesn't work anymore, so running it without sudo no longer works. So on the one hand, the issue is with the command I'm using (I'll need to fix my sudoers whitelist), and on the other hand, I don't think i3status-rs should fail in a way that freezes the whole system when a block uses a custom command that fails without sudo, so this might be a valid bug?
