Description

When installed via DLL the script editor crashes navigating tabs when many are open

thread '<unnamed>' (5478342) panicked at /Users/tristanpoland/.cargo/git/checkouts/wgpui-c42402163a03b4ee/98e312e/src/app/entity_map.rs:272:13:
Leases must be ended with EntityMap::end_lease
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

thread '<unnamed>' (5478342) panicked at /rustc/ac68faa20c58cbccd01ee7208bf3b6e93a7d7f96/library/core/src/panicking.rs:233:5:
panic in a destructor during cleanup
thread caused non-unwinding panic. aborting.
zsh: abort      cargo run --release

To recreate

  • Install the code editor plugin's DLL to a compatible engine version
  • open a handful of scripts in tabs (10 or so)
  • Click around the tabs rapidly and randomly
  • Observe crash

Thoughts

This is likely related to UI state+DLL boundary issues rather than an issue specifically with the code editor

Contributor guide

Research direction
Investigate the panic at entity map.rs:272. Check if lease management is properly handled across DLL boundaries. Reproduce the crash and trace the lease lifecycle.
