Cutter freezes when scrolling disassembly #3328

Open praschke opened 3 months ago

praschke commented 3 months ago

Environment information

Describe the bug

Scrolling too quickly in the disassembly freezes Cutter.

To Reproduce

Steps to reproduce the behavior:

  1. Open Cutter in a wayland session and analyze the attached binary.
  2. Click on Disassembly.
  3. Scroll vigorously.
  4. Cutter freezes.

Expected behavior

Cutter doesn't freeze.

Additional context

The freeze only occurs on Wayland. On Xwayland it functions normally.

If you scroll at moderate speed do you see a bunch of warnings in the builtin console widget?

also now i'm not so sure that wayland is related, i'm now getting freezes in X when trying to open the same executable again.

Ok this looks like combination of two problems:

Rot127 commented 2 months ago

I cannot reproduce it on Debian. And the PCRE2 and NixOS issues don't mention problems with JIT anywhere. This will need a little time until I have set up a NixOS VM. Also because we want to report this to the PCRE2 folks. But we could just disable JIT for NixOS as well.

Rot127 commented 2 months ago

@praschke Setting up NixOS takes pretty long for me (installing qt6/5 doesn't work and more). And I don't know unfortunately, when I will find time to take care of it.

So if you are willing, you can test the following patches, which disables JIT for the regex engine.

If they do work, it means NixOS has problems with the PCRE2 JIT as well. We shoud report this in https://github.com/NixOS/nixpkgs/issues/300056 in this case. And than see how they'd like to solve it.

Diffs

They are for rizin. Not for Cutter. So they need to be applied in the rizin submodule.
