A glTF Tools Problem Reproduction Project

A glTF Tools Problem Reproduction Project

An extension that only exists to reproduce a problem with the glTF Tools extension.

This extension (called Bencoder) has a function for bencoding JavaScript values. The function can't encode a JavaScript function in a meaningful way, but will encode it in some way. Unless, and this is the problem, the glTF Tools extension has been activated.

After activating the glTF Tools extension, encoding a function with the Bencode extension will cause the bencode function to enter an infinit recursion.

Steps to reproduce

0. Have the glTF Tools extension installed and enabled
1. Open this project (the Bencoder extension project) in VS Code
2. Press F5 to launch the Extension Host in the sub folder a-gltf-project.
3. From the Command Palette, run *Bencode Hello World
   • This bencodes a JavaScript object looking like so: {message: "Hello World from bencoder!"}
   • The result of the bencoding should pop up in an information message toast.
4. From the Command Palette, run Bencode a Function Object
   • This bencodes a JavaScript function defined like so: function(){}
   • The result of the bencoding should pop up in an information message toast.
   • Run the function more times to convince yourself that it works (for some defintion of “works”).
5. Open and then close the Box.gltf file.
6. From the Command Palette, run Bencode a Function Object
   • Expected: The result of the bencoding should pop up in an information message toast.
   • Actual: An error modal pops up with the message:

     Command 'Bencode a Function Object' resulted in an error Maximum call stack size exceeded

The command for bencoding the Hello World object keeps working. The command for bencoding a function will not work until the VS Code window is reloaded.
