sync error #45

Iwark · 2022-10-21T08:02:46Z

Hello! Thanks for the great work 👍
Let me submit a bug report here.

Example code:

Let's say there's a Diff model to record every update from yjs doc.
The following code will raise an exception.

doc = Y::Doc.new
Page.first.diffs.order(:id).take(50).pluck(:diff).each do |diff|
  doc.sync(diff)
end

Exception:

thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', /home/runner/work/yrb/yrb/tmp/cargo-vendor/yrs/src/block.rs:125:82
/app/vendor/bundle/ruby/3.1.0/gems/y-rb-0.3.0-aarch64-linux/lib/y/transaction.rb:22:in `ytransaction_apply_update': called `Option::unwrap()` on a `None` value (fatal)

Here's some other information that may help solve the bug:

If I take 40 diffs instead of 50, it works correctly.
If I give the same data to javascript yjs, then Y.applyUpdate can handle them properly without any errors.
- It's my workaround to return every diff to the client for now.

// This works 
diffs.forEach((diff) => {
  Y.applyUpdate(this.ydoc, Uint8Array.from(diff))
})

Here are the 50 diffs I used above.

maybe It's related to this issue?

Thanks!

@Iwark thanks for reporting. I am going to take a look.

Could you provide which type (Map, Array, Text, XMLElement, XMLText) and ID you use, e.g. doc.get_text("id")?

I can narrow down the issue to two updates (index: 1, 2), the others seem to work.

eliias · 2022-10-21T10:20:29Z

I have decoded the two updates, and I can't really see a problem. I then skipped the other updates and they worked, so I thought it might be conflicting updates and I found the pair that caused the issue. @Horusiath could you help here?

@eliias Could you tell some details about the environment? I'm running your Rust debug example in windows rustc 1.65.0-nightly, yrs main branch (v0.12), and this check executes without issues. I can try to use macos as well, but I need to confirm if this issue is related to a particular build or not.

@Horusiath I can deterministically produce the error on a M1/Arm64 (MacOS 12.6), rustc version 1.63.0. I updated to 1.64.0, but same result. yrs is on 0.12 (the crate, not the main branch).
