fix: remove GBulb, require PyGObject 3.50.0+ by HastD · Pull Reque...

According to the documentation, GBulb is unnecessary and non-functional with recent versions of PyGObject. I removed GBulb, bumped the minimum required version of PyGObject to 3.50.0, and modified ...

Ttulip man i wish we could use the rpm-ostree rechunker

Zeglius•4/18/25, 2:14 PM

About that, I thought of something really dumb. Can we rechunk, but instead of relying on rpm-ostree, doing it manually with containerfiles

COPY

COPY

antheas•4/18/25, 2:16 PM

No, you'd need to fork buildah

antheas•4/18/25, 2:17 PM

I built rechunk I thought about that

Zeglius•4/18/25, 2:17 PM

Isn't rechunking just copying package related files into a layer?

antheas•4/18/25, 2:17 PM

You can't do dynamic copy instructions

Zeglius•4/18/25, 2:17 PM

Oh you can with dagger

antheas•4/18/25, 2:17 PM

You can't ensure the layer has the correct file order

all set!

Zeglius•4/18/25, 2:17 PM

File order?

antheas•4/18/25, 2:17 PM

And fix the timestamps

antheas•4/18/25, 2:17 PM

Yes

antheas•4/18/25, 2:18 PM

In order for a layer to have the same hash you need the same tar atream

antheas•4/18/25, 2:18 PM

The only tool that can create custom tar streams is ostree RS ext

Zeglius•4/18/25, 2:18 PM

Could someone in theory do the same with just the tar command?

antheas•4/18/25, 2:18 PM

Could you in theory rebuild ostree RS ext?

antheas•4/18/25, 2:18 PM

Yes

antheas•4/18/25, 2:19 PM

But it exists already so

Zeglius•4/18/25, 2:19 PM

Yeah but it depends on buildah I'm assuming

antheas•4/18/25, 2:19 PM

Ostree RS ext builds tar streams manually

Zeglius•4/18/25, 2:20 PM

Mmm ideally I would get rid of ostree dependency completely on CI

antheas•4/18/25, 2:20 PM

Then you eat that on deployment

antheas•4/18/25, 2:20 PM

Either you make the commit or the client does and it explodes

ZZeglius Mmm ideally I would get rid of ostree dependency completely on CI

Robert•4/18/25, 2:21 PM

Honestly, I'd wait and see how things pan out with composefs.
This will remove ostree dependency throughout the entire stack

Zeglius•4/18/25, 2:21 PM

Well yeah, still need to figure out how to do rechunking

antheas•4/18/25, 2:21 PM

Ostree is still the backend and there is no proposed replacement

antheas•4/18/25, 2:22 PM

They're just trying to obfuscate it

Robert•4/18/25, 2:22 PM

The composefs-rs project is a Rust implementation of composefs that is capable of generating composefs images from container images.

We should integrate it in bootc as an alternative to the ostree backend.

antheas•4/18/25, 2:22 PM

Damn Colin has been busy

Zeglius•4/18/25, 2:22 PM

Ah, right, because it already handles the deduplication

Zeglius•4/18/25, 2:23 PM

Nvm then

antheas•4/18/25, 2:23 PM

Nothing here is currently expected to be useful to anybody at all, and probably never will be. If these experiments go well, this code will probably end up merged in other places.

Zeglius•4/18/25, 2:23 PM

Wait nvm still need it, otherwise we end up downloading all the layers

antheas•4/18/25, 2:23 PM

Look all rechunk is is a grouping algorithm for files that wraps ostree RS ext

antheas•4/18/25, 2:24 PM

It's not backend dependent but there is no other backend

antheas•4/18/25, 2:24 PM

It's also not particularly insightful, it just works
