4.6 iOS 64-bit beta

Hi.

Seem to have a IL2CPP crash under 4.6.6 that I didn't have yesterday with 4.6.5.

In il2cpp::vm::Runtime::GetInterfaceInvokeData(unsigned int, TypeInfo*, void*). Happens every time on dev and non-dev builds.

Have sent complete project.
Bug #702922.

 

Just grabbed the new 4.6.6p1 patch build and while I was building fine on 4.6.6f2, I'm now getting a compile error:

IL2CPP error for type 'Matrix.XPathFilter' in assembly '/Users/username/Documents/code/project-trunk/games/project/Temp/StagingArea/Data/Managed/Matrix.dll'
Additional information: Build a development build for more information. Cannot cast from source type to destination type.

Output from the development build is:

Getting an exception in IL2CPP under 4.6.6 with the System.Net.HTTPListener.Stop method:

NotSupportedException: /Users/builduser/buildslave/unity/build/Tools/il2cpp/il2cpp/libil2cpp/icalls/mscorlib/System.Threading/Thread.cpp(366) : Unsupported internal call for IL2CPP:Thread::Abort_internal - "Thread abortion is currently not implemented on IL2CPP; it is recommended to use safer mechanisms to terminate threads."



I realize Thread.Abort is not supported, but there does not seem to be a workaround for this.

Unrelated: Are you aware of the odd stack trace dumps being reported in exceptions and log statements? 9/10 it seems the stack trace is nonsense.

 

Just wanted to report that we're seeing an order of ~40MB memory usage reduction (specifically in System.ExecutableAndDlls, both in Unity's profiler and Xcode's) thanks to upgrading to the latest patch release 4.6.6p1

 

Hey Josh quick question, does the new unity 5.1 contain the patch rollup through 5.0.2p4? I didnt see anything in the release notes about il2cpp.

Thanks man

 

Just wanted to add that this issue also occurs in 4.6.6p1.

 

@JoshPeterson

Exactly how to fix it?

 

We are seeing a new issue in the 4.6.6p1 version that does not occur in 4.6.6. When trying to build with IL2CPP we get the following error with a third party DLL:

IL2CPP error for type 'Matrix.XPathFilter' in assembly '/il2cpp_playground/Temp/StagingArea/Data/Managed/Matrix.dll'
Additional information: Build a development build for more information. Cannot cast from source type to destination type.

A development build reveals:

Unhandled Exception: System.InvalidCastException: Cannot cast from source type to destination type.
at Unity.IL2CPP.Metadata.Fields.FieldDefaultValue.ConstantDataFor (Mono.Cecil.FieldDefinition field) [0x00000] in <filename unknown>:0

I have submitted a bug report with more details and full strack trace, number is 703294

 

@JoshPeterson The size of the xcodeproj file generated by Unity for our project has increased from 200 kB to a whopping 5.4 MB in Unity 4.6.6.

 

Considering how many .cpp and .h files it includes, that is hardly surprising.

 

To be clear, I'm talking about a difference between 4.6.5 and 4.6.6p1. Why does the new version generate that many more .cpp and .h files? Already the previous build had plenty.

The problem with a 5 MB project file is that the post processors are not built for so massive files. Our build time increased from 15 minutes to 30 minutes, mostly spent in post processors. Compare that to 3 minutes it used to be with a 32 bit build.

 

@JoshPeterson Just found and reported a bug in Unity 4.6.6p1 when building with IL2CPP. I think it happens in older versions of Unity as well.
The method "Directory.GetFiles(strSearchPath, strSearchPattern)" doesn't work in some usage situation on IL2CPP builds. It works ok on Mono builds.

More specifically, if you use a more complex search pattern for the 2nd parameter for example, "partialFileName_*.ext", it will always return zero results even if you have such files in the specified path. On Mono builds it works ok.

If you call it using the search pattern "*.ext" it will work ok and return a list of all the files that have the extension "ext".

The case number is: 703908.

 

Hey,

I think i have found a bug with IL2CPP.
We are using the json.net port for unity (version 4.6.6)
I might add that this was not present in the earlier unity version we used (4.6.4), so it could be a regression.

The code that is throwing the error looks like this:
uint8_t L_3 = (( uint8_t (*) (Object_t * /* static, unused */, JToken_t225 *, const MethodInfo*))IL2CPP_RGCTX_METHOD_INFO(method->rgctx_data, 0)->method)(NULL /*static, unused*/, (JToken_t225 *)L_2, /*hidden argument*/IL2CPP_RGCTX_METHOD_INFO(method->rgctx_data, 0));

(This throws a EXC_BAD_ACCESS in runtime when using the jToken.Value<T>(key))

It appears there is no NULL checking or handling here.
Let me know if i have repeated a known bug or if this is new.

Cheers

 

We are now into 64bit and are able to build properly since 4.6.5p2. We are currently on 4.6.6p1 and running into a couple of issues that have been occurring after 4.6.2p3. Our pre-June release was using 4.6.2p3 as we were still able to build to 32 bit for iOS submission. Now with the 64 bit requirement, we need to be on these later builds that have the following issues:

The main one is the frame rate increase that has been pending since April. This is really slowing down older devices and particularly devices still running iOS 7.

The next one is slightly minor but also started occurring at the same time. It has to do with the caret position on input text fields in UI.

Yes, i will put a project together.
I can also chime in with more info on this.
The problem appears to be when casting to generic type of bool.

Could this be an assumption of byte length 1, i think bools are 4 bytes in .net.
Just an idea.

The creator of the json.net library (talked to him) seems to think something similar as well.
The workaround was to not use bools but strings and then recast the return string value to bool.

Cheers

 

Found out it has to do with either the Facebook or Parse plugin. Always fun

 

I encountered an issue involving weird callstacks and serialization errors such as this one:

This wasn't happening when using Mono.

I found that if you have two different components in different assemblies sharing the same name (ie one MyScript.cs in a "standard" folder and one MyScript.cs in a Plugins folder), the player could get confused and use the code from the wrong assembly.

I submitted a bug with an example project: id 704197.

 

Hi. I know this is 4.6 thread but....
Seems we have problem with IL2CPP. (Unity5.0.3p1).The same project is behaving differently IL2CPP and Mono 2x
After several reload the main game field we receive "Received memory warning.WARNING -> applicationDidReceiveMemoryWarning()". On each reload, we increase the memory usage ~30MB. When the memory usage more then >302MB application stop.
We also have mono 2x build. And it is working properly. Memory usage after 5 reload : ~240 MB

I added a screenshots. On the first two (mono build) : mono1- after the start, mono2 -after 4 reload
On the second (IL2CPP) x64_1- after the start, x64_2 -after 4 reload

What we need to do to properly submit issue?

 

@JoshPeterson
I assume the fact that the app is killed by iOS (low memory warning) with IL2CPP and lives forever with mono isn't that unreliable.

 

Well, we (work at the same company as achooley) just cannot resumbit the app to Apple, so sorry if my reaction was a bit harsh as well .

So, we'll submit full project with bug report (not sure if it passes QA though) and try to get more specific info using Instruments. Anything we should look at first place, coz never used Instruments as always worked with Unity Profiler?

 

About the conversion between structure and byte stream, we use Marshal.PtrToStructure/Marshal.StructureToPtr to do the trick in our project.
For a complex structure which contains array, it doesn’t work on IOS, because of JIT/AOT or whatever.

For structure like this:

Code (CSharp):

1. [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode, Pack = 1)]
2. public struct Login_struct
3. {
4.     [MarshalAs(UnmanagedType.ByValArray, SizeConst = 12)]
5.     public char[] account;
6.     [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32)]
7.     public char[] password;
8.     [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32)]
9.     public char[] email;
10. }

Marshal tool cannot work properly, it can get the proper size of the structure, but cannot convert between intptr and structure.

Luckily, we can define the structure to be continuous in memory, so we use a memcpy plugin to dump structure or byte stream from memory and do the conversion.
——————————————————————
This method helps us to solve the issue about serialize/deserialize of structure（contains array）on IOS, and works properly under Mono.

But il2cpp just ruins it all. After il2cpp, the arrays in structure are replaced by 3 pointers. From Xcode I can tell those 3 pointers are not continuous in memory, which means the plugin we used to use cannot work properly any longer. The size of the structure even changes to 8*3=24(64bit), but not (12+32+32)*2(Unicode char) which we defined in C#.

I’m afraid there is a bug that il2cpp doesn’t fully inherit the information from C# code, and it has a big influence on our project. I have no choice but counting on you guys now, please help me.

I can also provide a test demo if necessary.

Thanks a lot

 

Sure, Case 704696. Please take a look.
@JoshPeterson

 

@JoshPeterson

I just checked and the new file is 32 times larger. I think there are some extra files there but I think the biggest problem is that the whole format of the file is different. It's now XML! Is there some setting I can change to fix that?

What email address could I use to send the project files to you guys for inspection?

 

Hi,

I found an issue with respect to the treatment of NaNs when compiling with IL2CPP (at least for iOS): when comparing a NaN to another number, the result should be universally false, but it actually yields true instead. This leads to all kinds of undesired behaviour in various Mathf and Vector routines, and makes it really difficult to track down bugs due to the fact that the editor and the device behave differently.

Here's a simple example to reproduce the issue, just compile it for iOS:

Code (CSharp):

1. Test code:
2.  
3. Debug.Log("===== Start NaN handling test =====");
4. var nan2 = new Vector2(float.NaN, float.NaN);
5. Debug.Log("Mathf.Clamp01(NaN) = " + Mathf.Clamp01(float.NaN));
6. Debug.Log("Mathf.Sign(NaN) = " + Mathf.Sign(float.NaN));
7. Debug.Log("Mathf.Sqrt(NaN) = " + Mathf.Sqrt(float.NaN));
8. Debug.Log("Mathf.Lerp(NaN, 0, 0) = " + Mathf.Lerp(float.NaN, 0f, 0f));
9. Debug.Log("Mathf.Lerp(NaN, 0, 0.5) = " + Mathf.Lerp(float.NaN, 0f, 0.5f));
10. Debug.Log("Mathf.Lerp(NaN, 0, 1) = " + Mathf.Lerp(float.NaN, 0f, 1f));
11. Debug.Log("Mathf.Lerp(NaN, 0, NaN) = " + Mathf.Lerp(float.NaN, 0f, float.NaN));
12. Debug.Log("Mathf.Lerp(1, 0, NaN) = " + Mathf.Lerp(1f, 0f, float.NaN));
13. if (float.NaN > 10)
14. {
15.     Debug.Log("NaN > 10: IMPOSSIBLE!");
16. }
17. if (float.NaN < 10)
18. {
19.     Debug.Log("NaN < 10: IMPOSSIBLE!");
20. }
21. var newNaN = Mathf.Sqrt(-1f);
22. Debug.Log("newNaN = " + newNaN);
23. if (newNaN > 10)
24. {
25.     Debug.Log("newNaN > 10: IMPOSSIBLE!");
26. }
27. if (newNaN < 10)
28. {
29.     Debug.Log("newNaN < 10: IMPOSSIBLE!");
30. }
31. Debug.Log("nan2.magnitude = " + nan2.magnitude);
32. Debug.Log("nan2.normalized = " + nan2.normalized);
33. Debug.Log("Vector2.Distance(nan2, zero) = " + Vector2.Distance(nan2, Vector2.zero));
34. Debug.Log("Vector2.Lerp(nan2, zero, 0) = " + Vector2.Lerp(nan2, Vector2.zero, 0f));
35. Debug.Log("Vector2.Lerp(nan2, zero, 0.5) = " + Vector2.Lerp(nan2, Vector2.zero, 0.5f));
36. Debug.Log("Vector2.Lerp(nan2, zero, 1) = " + Vector2.Lerp(nan2, Vector2.zero, 1f));
37. Debug.Log("Vector2.Lerp(nan2, zero, NaN) = " + Vector2.Lerp(nan2, Vector2.zero, float.NaN));
38. Debug.Log("Vector2.Lerp(one, zero, NaN) = " + Vector2.Lerp(Vector2.one, Vector2.zero, float.NaN));
39. Debug.Log("===== End NaN handling test =====");
40.

I believe the XML is some old format, which shouldn't be used. Please confirm you are seeing the same behaviour.

 

@povilas Really interesting. I guess I have to believe you but how could this behaviour have changed between 4.6.5 and 4.6.6? Only Unity version was changed, the sources are 100% identical.

Also please confirm that your project.pbxproj is NOT xml in 4.6.6.
