GlobalizationNative_LoadICUData never called when using Invariant mode (Mac Catalyst and other Apple platforms) #2759

rolfbjarne · 2022-04-20T16:55:37Z

Description

The problem occurs on Apple platforms (Mac Catalyst, iOS) when using .NET 7.

The initial symptom I get is this exception at startup:

Arg_ExternalException (System.Runtime.InteropServices.ExternalException)
   at System.Globalization.CompareInfo.SortHandleCache.GetCachedSortHandle(String )
   at System.Globalization.CompareInfo.IcuInitSortHandle(String )
   at System.Globalization.CompareInfo.InitSort(CultureInfo )
   at System.Globalization.CompareInfo..ctor(CultureInfo )
   at System.Globalization.CultureInfo.get_CompareInfo()
   at System.Globalization.CompareInfo..cctor()

Debugging in lldb shows that this occurs due to an error in ICU, the udata_openChoice function returns an error here:

(lldb) bt

Debugging a bit more reveals that GlobalizationNative_LoadICUData is never called, and I'm guessing this is the underlying cause for the exceptions above.

Now the question obviously becomes why GlobalizationNative_LoadICUData is never called.

Usually GlobalizationNative_LoadICUData is called like this (for another test app that works fine):

So I traced all managed code (setting MONO_TRACE=all): iTerm2 Session 20 Apr 2022 at 6:28:03 PM.txt.zip

And I found that:

System.Globalization.GlobalizationMode/Settings:.cctor is never called.
System.Globalization.GlobalizationMode:get_Invariant is never called.
However, System.Globalization.CultureData:CreateCultureWithInvariantData is called.

Then I compared the IL for System.Globalization.CultureData:CreateCultureWithInvariantData between a working app and a failing app, and it turns out there's no call to System.Globalization.GlobalizationMode:get_Invariant in the failing app.

I'm guessing the linker linked it away.

App that fails: BundleStructure.app.zip - download, unzip, and execute ./BundleStructure.app/Contents/MacOS/BundleStructure in Terminal to see the exception (due to a different issue on our side the app ends up in an infinite loop, but this is the cause for the loop in the first place).

Note: this is not a problem in .NET 6, only in .NET 7.

Reproduction Steps

If the above description isn't enough, I can try to find a way to reproduce it.

Expected behavior

No exception at startup

Actual behavior

See above

Regression?

Yes.

This started happened when maestro did this bump: xamarin/xamarin-macios@d9eacac.

Issue Details

Description

The problem occurs on Apple platforms (Mac Catalyst, iOS) when using .NET 7.

The initial symptom I get is this exception at startup:

Arg_ExternalException (System.Runtime.InteropServices.ExternalException)
   at System.Globalization.CompareInfo.SortHandleCache.GetCachedSortHandle(String )
   at System.Globalization.CompareInfo.IcuInitSortHandle(String )
   at System.Globalization.CompareInfo.InitSort(CultureInfo )
   at System.Globalization.CompareInfo..ctor(CultureInfo )
   at System.Globalization.CultureInfo.get_CompareInfo()
   at System.Globalization.CompareInfo..cctor()

Debugging in lldb shows that this occurs due to an error in ICU, the udata_openChoice function returns an error here:

Now the question obviously becomes why GlobalizationNative_LoadICUData is never called.

Usually GlobalizationNative_LoadICUData is called like this (for another test app that works fine):

So I traced all managed code (setting MONO_TRACE=all): iTerm2 Session 20 Apr 2022 at 6:28:03 PM.txt.zip

And I found that:

System.Globalization.GlobalizationMode/Settings:.cctor is never called.
System.Globalization.GlobalizationMode:get_Invariant is never called.
However, System.Globalization.CultureData:CreateCultureWithInvariantData is called.

Then I compared the IL for System.Globalization.CultureData:CreateCultureWithInvariantData between a working app and a failing app, and it turns out there's no call to System.Globalization.GlobalizationMode:get_Invariant in the failing app.

I'm guessing the linker linked it away.

App that fails: BundleStructure.app.zip - download, unzip, and execute ./BundleStructure.app/Contents/MacOS/BundleStructure in Terminal to see the exception (due to a different issue on our side the app ends up in an infinite loop, but this is the cause for the loop in the first place).

Note: this is not a problem in .NET 6, only in .NET 7.

Reproduction Steps

If the above description isn't enough, I can try to find a way to reproduce it.

Expected behavior

No exception at startup

Actual behavior

See above

Regression?

Yes.

This started happened when maestro did this bump: xamarin/xamarin-macios@d9eacac.

Issue Details

Description

The problem occurs on Apple platforms (Mac Catalyst, iOS) when using .NET 7.

The initial symptom I get is this exception at startup:

Arg_ExternalException (System.Runtime.InteropServices.ExternalException)
   at System.Globalization.CompareInfo.SortHandleCache.GetCachedSortHandle(String )
   at System.Globalization.CompareInfo.IcuInitSortHandle(String )
   at System.Globalization.CompareInfo.InitSort(CultureInfo )
   at System.Globalization.CompareInfo..ctor(CultureInfo )
   at System.Globalization.CultureInfo.get_CompareInfo()
   at System.Globalization.CompareInfo..cctor()

Debugging in lldb shows that this occurs due to an error in ICU, the udata_openChoice function returns an error here:

Debugging a bit more reveals that GlobalizationNative_LoadICUData is never called, and I'm guessing this is the underlying cause for the exceptions above.

Now the question obviously becomes why GlobalizationNative_LoadICUData is never called.

Usually GlobalizationNative_LoadICUData is called like this (for another test app that works fine):

So I traced all managed code (setting MONO_TRACE=all): iTerm2 Session 20 Apr 2022 at 6:28:03 PM.txt.zip

And I found that:

System.Globalization.GlobalizationMode/Settings:.cctor is never called.
System.Globalization.GlobalizationMode:get_Invariant is never called.
However, System.Globalization.CultureData:CreateCultureWithInvariantData is called.

Then I compared the IL for System.Globalization.CultureData:CreateCultureWithInvariantData between a working app and a failing app, and it turns out there's no call to System.Globalization.GlobalizationMode:get_Invariant in the failing app.

I'm guessing the linker linked it away.

App that fails: BundleStructure.app.zip - download, unzip, and execute ./BundleStructure.app/Contents/MacOS/BundleStructure in Terminal to see the exception (due to a different issue on our side the app ends up in an infinite loop, but this is the cause for the loop in the first place).

Note: this is not a problem in .NET 6, only in .NET 7.

Reproduction Steps

If the above description isn't enough, I can try to find a way to reproduce it.

Expected behavior

No exception at startup

Actual behavior

See above

Regression?

Yes.

This started happened when maestro did this bump: xamarin/xamarin-macios@d9eacac.

If you're using Invariant mode, I don't believe loading icu should be called at all.

tarekgh · 2022-04-20T17:10:58Z

A quick note, when enabling the invariant mode, it is expected that GlobalizationNative_LoadICUData not get called. But GlobalizationMode.Invariant should get called. And the IcuInitSortHandle should return early in the line
https://source.dot.net/#System.Private.CoreLib/CompareInfo.Icu.cs,21.

@steveisok could be the linker trimmed all invariant mode code somehow disabling all Invariant mode code paths?

steveisok · 2022-04-20T17:12:10Z

@steveisok could be the linker trimmed all invariant mode code somehow disabling all Invariant mode code paths?

That would be my guess. @rolfbjarne can you validate?

rolfbjarne · 2022-04-21T07:26:46Z

I got the logic reversed, this is when Invariant=false, but the problem is really the same, that the call to System.Globalization.GlobalizationMode/Settings.get_Invariant is inlined, and thus the Settings static constructor isn't called.

This is the decompiled IcuInitSortHandle:

This call to GlobalizationMode.Invariant is also removed: https://source.dot.net/#System.Private.CoreLib/CultureData.cs,651

See end of the decompiled CreateCultureWithInvariantData:

The maestro bump that resulted in this failure includes a linker bump: e8b0ba0...3292e23, which includes this interesting commit: Add constant propagation through methods with parameters or complex bodies, maybe that's got something to do with it?

marek-safar · 2022-04-21T09:31:16Z

This looks like linker related so I'll look into it.

tlakollo · 2022-04-25T01:12:59Z

I see an entry in the runtime substitution files that shortcircuits both GlobalizationMode.get_Invariant() and GlobalizationMode/Settings.getInvariant() to a specific boolean value. See https://github.com/dotnet/runtime/blob/main/src/libraries/System.Private.CoreLib/src/ILLink/ILLink.Substitutions.Shared.xml#L11-L17

marek-safar · 2022-04-25T08:39:35Z

As I wrote I'm looking into it and have local fix already

rolfbjarne · 2022-05-05T07:01:55Z

@marek-safar any idea when this can be fixed?

jonathanpeppers · 2022-05-11T21:05:10Z

I tried a @(TrimmerRootDescriptor) like:

<?xml version="1.0" encoding="utf-8" ?>
<linker>
	<assembly fullname="System.Private.CoreLib">
		<type fullname="System.Globalization.GlobalizationMode" preserve="all" />
	</assembly>
</linker>

This preserves members like GlobalizationMode.Invariant, but it still seems to trim away some of the if-statements that cause this problem.

@marek-safar is there another workaround we could try? I was going to put something in the Android workload for now to get us on a newer .NET 7.
