Resolved Editor hangs with Profiling Progress - Parsing Profiler Data: 0/xxxkb processed

Guedez · Jul 10, 2020

As in the picture:

Since it's not a crash, I have no idea how to send any kind of related stack trace
Happens in 2020.1.0b14
Could be related to "Profiler: Fixed profiler collecting samples when Playmode is paused (1244286)" fixed in b15

Update: Still happens in b15

If you have a project where you're able to reproduce this issue, please submit a bug-report as described in this document:
https://unity3d.com/unity/qa/bug-reporting

It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

Bug Report Number: 1̶2̶6̶2̶8̶7̶8 1262892, the bug report needed to be uploaded twice due to connection failure. I can only hope the second one actually went with the files.

And I think I found the issue.
The player was also crashing when attempting to close it. I attached the debugger and got this here:
The code gets stuck at Library\PackageCache\com.unity.ui@1.0.0-preview.3\Core\Renderer\UIRenderer\UIRenderDevice.cs line 1057
I had not made the connection yet, but the issue did start quickly after updating my UI Toolkit to the new
"com.unity.ui": "1.0.0-preview.3"
package.
Could be something else, but this seems very suspicious

Code (CSharp):

private static void ProcessDeviceFreeQueue()

{

s_MarkerFree.Begin();

if (m_SynchronousFree)

Utility.SyncRenderThread(); <<this line

var freeNode = m_DeviceFreeQueue.First;

while (freeNode != null)

{

if (!Utility.CPUFencePassed(freeNode.Value.handle))

break;

freeNode.Value.Dispose();

m_DeviceFreeQueue.RemoveFirst();

freeNode = m_DeviceFreeQueue.First;

}

// After synchronizing with the render thread, all cpu fences should pass.

Debug.Assert(!m_SynchronousFree || m_DeviceFreeQueue.Count == 0);

if (m_ActiveDeviceCount == 0 && m_SubscribedToNotifications)

{

if (s_WhiteTexel != null)

{

UIRUtility.Destroy(s_WhiteTexel);

s_WhiteTexel = null;

}

if (s_DefaultShaderInfoTexFloat != null)

{

UIRUtility.Destroy(s_DefaultShaderInfoTexFloat);

s_DefaultShaderInfoTexFloat = null;

}

if (s_DefaultShaderInfoTexARGB8 != null)

{

UIRUtility.Destroy(s_DefaultShaderInfoTexARGB8);

s_DefaultShaderInfoTexARGB8 = null;

}

Utility.NotifyOfUIREvents(false);

m_SubscribedToNotifications = false;

}

s_MarkerFree.End();

}

Another update, I caught unity hanging again and this time the debugger managed to get me some info. one of the threads was hanging here at
PackageCache\com.unity.ui@1.0.0-preview.3\Core\IMGUIContainer.cs:333
Hopefully it's relevant. Pressing F5 never steps into nor F6 steps over. It is permanently stuck there. Since I seem to be the only person with this issue, I wonder if it is not hanging while attempting to draw some custom window or inspector I made. The issue is that I don't really know how to get any info out of
onGUIHandler
. This is what the VS Inspector has to say about it:

Most relevant piece of code:

Code (CSharp):

try

{

using (new GUIClip.ParentClipScope(parentTransform, clippingRect))

{

onGUIHandler(); <<< This line

#if DEBUG_IMGUI_CONTAINER_EVENTS

Console.WriteLine($"{s_OnGUICounter++} {this.GetDisplayName()}.OnGUI({evt.rawType}>{Event.current.type})");

#endif

}

}

catch (Exception exception)

{

// only for layout events: we always intercept any exceptions to not interrupt event processing

if (originalEventType == EventType.Layout)

{

isExitGUIException = GUIUtility.IsExitGUIException(exception);

if (!isExitGUIException)

{

Debug.LogException(exception);

}

}

else

{

// rethrow event if not in layout

throw;

}

}

finally

Managed to detect and fix the issue. This was caused by a bunch of (at least 60000 but I didn't count)
NativeArrays 
were being allocated with
TempJob 
and failing to deallocate fast enough. I changed them all to Persistent and the issue stopped happening.

@Guedez Can you say how to do that. Iam currently having this issues

Guedez · Jun 28, 2021

It was an issue specific to my code, try checking every place you allocate native containers to see if there is something doing it excessively.
