From cbcceaf2bf78a17ffc12ff5c642064e0d6020d52 Mon Sep 17 00:00:00 2001 From: Marek Habersack Date: Tue, 31 Mar 2020 13:08:40 +0200 Subject: [PATCH] Return of the Strings Fixes: https://github.com/xamarin/xamarin-android/issues/4415 Context: https://github.com/xamarin/xamarin-android/commit/ce2bc689a19cb45f7d7bfdd371c16c54b018a020 This commit partially reverts ce2bc689a19cb45f7d7bfdd371c16c54b018a020 in the sense that it restores the use of type names for Java-to-Managed and Managed-to-Java type lookups for **Debug** builds only. The reason for the change is that in order for the MVID and type token based lookups to work we need two things: - for the MVID to remain unchanged in each mapped assembly - for the type token to remain unchanged in each mapped assembly However, in incremental builds neither of the above requirements is met **unless** the application is fully rebuilt and, thus, the typemaps are regenerated from scratch, which obviously doesn't sit well with the incremental nature of incremental builds :) With MVID/token id maps, every change to any source code that's built into a mapped assembly, may cause the assembly to change its MVID and renaming of any type, removing or adding a type, will rearrange the type definition table in the resulting assembly, thus changing the type token ids (which are basically offsets into the type definition table in the PE executable). This is what may cause an app to crash on the runtime with an exception similar to: android.runtime.JavaProxyThrowable: System.NotSupportedException: Cannot create instance of type 'com.glmsoftware.OBDNowProto.SettingsFragmentCompat': no Java peer type found. at Java.Interop.JniPeerMembers+JniInstanceMethods..ctor (System.Type declaringType) [0x0004b] in :0 at Java.Interop.JniPeerMembers+JniInstanceMethods.GetConstructorsForType (System.Type declaringType) [0x00031] in :0 at Java.Interop.JniPeerMembers+JniInstanceMethods.StartCreateInstance (System.String constructorSignature, System.Type declaringType, Java.Interop.JniArgumentValue* parameters) [0x00038] in :0 at AndroidX.Preference.PreferenceFragmentCompat..ctor () [0x00034] in <005e3ae6340747e1aea6d08b095cf286>:0 at com.glmsoftware.OBDNowProto.SettingsFragmentCompat..ctor () [0x00026] in :0 at com.glmsoftware.OBDNowProto.SettingsActivity.OnCreate (Android.OS.Bundle bundle) [0x00083] in :0 at Android.App.Activity.n_OnCreate_Landroid_os_Bundle_ (System.IntPtr jnienv, System.IntPtr native__this, System.IntPtr native_savedInstanceState) [0x00011] in :0 at (wrapper dynamic-method) Android.Runtime.DynamicMethodNameCounter.3(intptr,intptr,intptr) at crc64596a13587a898911.SettingsActivity.n_onCreate(Native Method) at crc64596a13587a898911.SettingsActivity.onCreate(SettingsActivity.java:40) at android.app.Activity.performCreate(Activity.java:7825) at android.app.Activity.performCreate(Activity.java:7814) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1306) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3245) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3409) at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:83) at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:135) at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:95) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2016) at android.os.Handler.dispatchMessage(Handler.java:107) at android.os.Looper.loop(Looper.java:214) at android.app.ActivityThread.main(ActivityThread.java:7356) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:492) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:930) Thus, we need to revert the Debug builds to the variation of the old string-based type name mapping. This commit implements it in a slightly leaner form than it was implemented before ce2bc689a19cb45f7d7bfdd371c16c54b018a020 landed in that only one copy of each set of type names (Java and managed) is maintained in both memory and on disk, at a tiny (sub millisecond) expense at the run time to fix up pointers between the two tables. --- src/Mono.Android/Android.Runtime/JNIEnv.cs | 20 +- .../Tasks/GenerateJavaStubs.cs | 2 +- .../ARMNativeAssemblerTargetProvider.cs | 1 + .../NativeAssemblerTargetProvider.cs | 1 + .../Utilities/NativeTypeMappingData.cs | 14 +- .../Utilities/TypeMapGenerator.cs | 360 +++++++++----- ...TypeMappingDebugNativeAssemblyGenerator.cs | 136 ++++++ ...eMappingReleaseNativeAssemblyGenerator.cs} | 20 +- .../X86NativeAssemblerTargetProvider.cs | 1 + .../Xamarin.Android.Common.targets | 4 + src/monodroid/CMakeLists.txt | 15 +- src/monodroid/jni/application_dso_stub.cc | 27 ++ src/monodroid/jni/embedded-assemblies.cc | 453 +++++++++++------- src/monodroid/jni/embedded-assemblies.hh | 23 +- src/monodroid/jni/external-api.cc | 6 - src/monodroid/jni/monodroid-glue-internal.hh | 3 + src/monodroid/jni/monodroid-glue.cc | 8 + src/monodroid/jni/xamarin-app.hh | 34 +- 18 files changed, 774 insertions(+), 354 deletions(-) create mode 100644 src/Xamarin.Android.Build.Tasks/Utilities/TypeMappingDebugNativeAssemblyGenerator.cs rename src/Xamarin.Android.Build.Tasks/Utilities/{TypeMappingNativeAssemblyGenerator.cs => TypeMappingReleaseNativeAssemblyGenerator.cs} (90%) diff --git a/src/Mono.Android/Android.Runtime/JNIEnv.cs b/src/Mono.Android/Android.Runtime/JNIEnv.cs index 04774035485..85ca85536fe 100644 --- a/src/Mono.Android/Android.Runtime/JNIEnv.cs +++ b/src/Mono.Android/Android.Runtime/JNIEnv.cs @@ -670,8 +670,9 @@ public static string GetClassNameFromInstance (IntPtr jobject) } } - [DllImport ("__Internal", CallingConvention = CallingConvention.Cdecl)] - static extern IntPtr monodroid_typemap_managed_to_java (byte[] mvid, int token); + // TODO: `type_name` is temporary, until https://github.com/mono/mono/issues/19377 is fixed + [MethodImplAttribute(MethodImplOptions.InternalCall)] + static extern unsafe IntPtr monodroid_typemap_managed_to_java (Type type, byte* mvid, string type_name); internal static void LogTypemapTrace (StackTrace st) { @@ -685,19 +686,24 @@ internal static void LogTypemapTrace (StackTrace st) } } - internal static string TypemapManagedToJava (Type type) + internal static unsafe string TypemapManagedToJava (Type type) { if (mvid_bytes == null) mvid_bytes = new byte[16]; - Span mvid = new Span(mvid_bytes); - byte[] mvid_slow = null; + var mvid = new Span(mvid_bytes); + byte[] mvid_data = null; if (!type.Module.ModuleVersionId.TryWriteBytes (mvid)) { monodroid_log (LogLevel.Warn, LogCategories.Default, $"Failed to obtain module MVID using the fast method, falling back to the slow one"); - mvid_slow = type.Module.ModuleVersionId.ToByteArray (); + mvid_data = type.Module.ModuleVersionId.ToByteArray (); + } else { + mvid_data = mvid_bytes; } - IntPtr ret = monodroid_typemap_managed_to_java (mvid_slow == null ? mvid_bytes : mvid_slow, type.MetadataToken); + IntPtr ret; + fixed (byte* mvidptr = mvid_data) { + ret = monodroid_typemap_managed_to_java (type, mvidptr, type.FullName); + } if (ret == IntPtr.Zero) { if (LogTypemapMissStackTrace) { diff --git a/src/Xamarin.Android.Build.Tasks/Tasks/GenerateJavaStubs.cs b/src/Xamarin.Android.Build.Tasks/Tasks/GenerateJavaStubs.cs index 2570de86a1d..a738f99f28e 100644 --- a/src/Xamarin.Android.Build.Tasks/Tasks/GenerateJavaStubs.cs +++ b/src/Xamarin.Android.Build.Tasks/Tasks/GenerateJavaStubs.cs @@ -402,7 +402,7 @@ void SaveResource (string resource, string filename, string destDir, Func types) { var tmg = new TypeMapGenerator ((string message) => Log.LogDebugMessage (message), SupportedAbis); - if (!tmg.Generate (SkipJniAddNativeMethodRegistrationAttributeScan, types, TypemapOutputDirectory, GenerateNativeAssembly, out ApplicationConfigTaskState appConfState)) + if (!tmg.Generate (Debug, SkipJniAddNativeMethodRegistrationAttributeScan, types, TypemapOutputDirectory, GenerateNativeAssembly, out ApplicationConfigTaskState appConfState)) throw new XamarinAndroidException (4308, Properties.Resources.XA4308); GeneratedBinaryTypeMaps = tmg.GeneratedBinaryTypeMaps.ToArray (); BuildEngine4.RegisterTaskObject (ApplicationConfigTaskState.RegisterTaskObjectKey, appConfState, RegisteredTaskObjectLifetime.Build, allowEarlyCollection: false); diff --git a/src/Xamarin.Android.Build.Tasks/Utilities/ARMNativeAssemblerTargetProvider.cs b/src/Xamarin.Android.Build.Tasks/Utilities/ARMNativeAssemblerTargetProvider.cs index e563f64ffe6..755e63fcd88 100644 --- a/src/Xamarin.Android.Build.Tasks/Utilities/ARMNativeAssemblerTargetProvider.cs +++ b/src/Xamarin.Android.Build.Tasks/Utilities/ARMNativeAssemblerTargetProvider.cs @@ -14,6 +14,7 @@ class ARMNativeAssemblerTargetProvider : NativeAssemblerTargetProvider public override string AbiName => Is64Bit ?
