Profiler hangs #88620

Open Wad67 opened 7 months ago

Wad67 commented 7 months ago

Tested versions

V4.2.1 stable b09f793f5

System information

Godot v4.2.1.stable - Ubuntu 23.04 23.04 - X11 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 6GB (nvidia; 535.146.02) - AMD Ryzen 5 2600X Six-Core Processor (12 Threads)

Issue description

When profiling particularly slow code, the profiler hangs, the graph shrinks as to indicate a huge peak but fails to show said huge peak. image

The game instance continues to run albeit at very reduced frame-rate, inputs are not handled. Including window buttons.

I would expect that profiling would work normally, a gigantic 6000ms or so peak appearing and game execution continuing as normal.

Steps to reproduce

Have a large project with a large convoluted procedural level generator written in GDscript. Attempt to profile it

Minimal reproduction project (MRP)

N/A

This is hard to do anything with, because you haven't provided any actionable reproduction steps, and a MRP is anything but nonapplicable.

The profiler received a crucial bugfix in 4.3, could you test if this bug still exists in that the latest dev version?

Wad67 commented 7 months ago

A convoluted procedural level generator is pretty much the opposite of a MRP, so I can't include that, no.

I will try the latest development version and report back, thanks.

I'm able to reproduce this issue with a build from master at 06d51891678e3abf360d6fcd2e8bd1ba96704fcc

The platformer demo suffices.

The steps to reproduce are:

  1. Run the project and start the profiler.
  2. Click on the profiler graph to inspect a certain data point.
  3. The running project should hang in some way -- user input should no longer work. The profiler also hangs.

Edit: I'm not sure if the way I'm reproducing it reflects the same issue described originally by @Wad67, but the profiler hangs either way.

Wad67 commented 6 months ago

This is more or less it, yes. I thought it was due to the size of the project, but evidently not.
