NWN.ProcessEventInfiniteLoopRepro

Repro project for a bug in Anvil that throws System.IndexOutOfRangeException from VirtualMachine.cs::ExecuteInScriptContext after having reloaded services that contain subscriptions to events that are also subscribed to from nss.

Getting started

Run

These are the steps to reproduce the bug:

1. Build and run

dotnet build -c Debug
./run-commands.sh # to start the interactive menu

2. Use option 5 to pack the module
3. Use option 1 to start the container
4. Use option 7 to tail the server logs
5. Log in and sell something to the merchant. This should work fine.
6. Trigger a reload of dotnet, e.g. by starting a watcher in a separate terminal and saving a file

dotnet watch --project NWN.ProcessEventInfiniteLoopRepro/Repro.csproj build -c Debug

7. Watch Anvil reload plugins.
8. Try to sell something again.
9. Observe the process crash.

Use

Use nasher to manage the sources.

A utility script named ./run-commands.sh has been added to speed up running frequent commands, inlcuding a useful watch-utility to hot compile scripts on file save (option 2).

Requirements

• docker (with compose)
• nasher
• dotnet
• entr (to hot compile nss)
