Description

The Apple mobile CoreCLR library test apps are published as a composite ReadyToRun image with IL bodies stripped, which the SDK turns on by default for iOS-like runtime identifiers. A stripped body is replaced with an invalid stub, so any test that needs the real IL at run time fails. System.Runtime.Loader.Tests, System.Reflection.DispatchProxy.Tests, and System.Xml.XmlSerializer.ReflectionOnly.Tests load assemblies into collectible AssemblyLoadContext instances, which cannot use the R2R native code and recompile from IL, so they throw InvalidProgramException; System.Reflection.Metadata.Tests reads a stripped method body directly and throws BadImageFormatException.

The on-Helix AOT build reads only the properties forwarded through the _ApplePropertyNames allowlist in tests.ioslike.targets, so this change adds PublishReadyToRunStripILBodies to that allowlist and sets it to false on these four test projects, leaving stripping on for every other Apple mobile CoreCLR test app.

Pull request overview

This PR updates the Apple mobile (“ioslike”) CoreCLR library test publish pipeline to preserve IL bodies for a small set of test projects that require IL at runtime, by explicitly disabling ReadyToRun IL-body stripping and ensuring that setting is forwarded through the Helix proxy-project property allowlist.

Changes:

  • Set PublishReadyToRunStripILBodies=false in four library test projects that need IL bodies at runtime.
  • Add PublishReadyToRunStripILBodies to the _ApplePropertyNames allowlist in eng/testing/tests.ioslike.targets so the Helix AOT/proxy build sees the project-level setting.

[clr-ios] Disable R2R IL-body stripping for more library tests that n…
a90733c
…eed IL at run time (#130468)
## Description
Follow-up to #130360. The SDK strips IL bodies from the Apple mobile
CoreCLR composite ReadyToRun image by default, replacing each body with
an invalid stub, so any test that needs the real IL at run time fails.
Three more projects hit this: `System.Runtime.Extensions.Tests`
(`AppDomainTests.ExecuteAssembly` invokes a stripped entry point,
`InvalidProgramException`), `System.IO.Hashing.Tests`
(`Crc64ParameterSet.ForwardCrc64.InitializeVectorized`, a `Vector128`
intrinsic fallback), and `System.Diagnostics.StackTrace.Tests` (the
runtime-async `V2Methods.Quuux` in `ToString_Async`). This sets
`PublishReadyToRunStripILBodies` to `false` on those three test
projects, which #130360 already forwards through the
`_ApplePropertyNames` allowlist, leaving stripping on for every other
Apple mobile CoreCLR test app.

Pull request overview
This PR updates the Apple mobile (“ioslike”) CoreCLR library test publish pipeline to preserve IL bodies for a small set of test projects that require IL at runtime, by explicitly disabling ReadyToRun IL-body stripping and ensuring that setting is forwarded through the Helix proxy-project property allowlist.
Changes:
  • Set PublishReadyToRunStripILBodies=false in four library test projects that need IL bodies at runtime.
  • Add PublishReadyToRunStripILBodies to the _ApplePropertyNames allowlist in eng/testing/tests.ioslike.targets so the Helix AOT/proxy build sees the project-level setting.

[clr-ios] Disable R2R IL-body stripping for more library tests that n…
a90733c
…eed IL at run time (#130468)
## Description
Follow-up to #130360. The SDK strips IL bodies from the Apple mobile
CoreCLR composite ReadyToRun image by default, replacing each body with
an invalid stub, so any test that needs the real IL at run time fails.
Three more projects hit this: `System.Runtime.Extensions.Tests`
(`AppDomainTests.ExecuteAssembly` invokes a stripped entry point,
`InvalidProgramException`), `System.IO.Hashing.Tests`
(`Crc64ParameterSet.ForwardCrc64.InitializeVectorized`, a `Vector128`
intrinsic fallback), and `System.Diagnostics.StackTrace.Tests` (the
runtime-async `V2Methods.Quuux` in `ToString_Async`). This sets
`PublishReadyToRunStripILBodies` to `false` on those three test
projects, which #130360 already forwards through the
`_ApplePropertyNames` allowlist, leaving stripping on for every other
Apple mobile CoreCLR test app.

## Description
The Apple mobile CoreCLR library test apps are published as a composite
ReadyToRun image with IL bodies stripped, which the SDK turns on by
default for iOS-like runtime identifiers. A stripped body is replaced
with an invalid stub, so any test that needs the real IL at run time
fails. `System.Runtime.Loader.Tests`,
`System.Reflection.DispatchProxy.Tests`, and
`System.Xml.XmlSerializer.ReflectionOnly.Tests` load assemblies into
collectible `AssemblyLoadContext` instances, which cannot use the R2R
native code and recompile from IL, so they throw
`InvalidProgramException`; `System.Reflection.Metadata.Tests` reads a
stripped method body directly and throws `BadImageFormatException`.
The on-Helix AOT build reads only the properties forwarded through the
`_ApplePropertyNames` allowlist in `tests.ioslike.targets`, so this
change adds `PublishReadyToRunStripILBodies` to that allowlist and sets
it to `false` on these four test projects, leaving stripping on for
every other Apple mobile CoreCLR test app.

[clr-ios] Disable R2R IL-body stripping for more library tests that n…
a90733c
…eed IL at run time (#130468)
## Description
Follow-up to #130360. The SDK strips IL bodies from the Apple mobile
CoreCLR composite ReadyToRun image by default, replacing each body with
an invalid stub, so any test that needs the real IL at run time fails.
Three more projects hit this: `System.Runtime.Extensions.Tests`
(`AppDomainTests.ExecuteAssembly` invokes a stripped entry point,
`InvalidProgramException`), `System.IO.Hashing.Tests`
(`Crc64ParameterSet.ForwardCrc64.InitializeVectorized`, a `Vector128`
intrinsic fallback), and `System.Diagnostics.StackTrace.Tests` (the
runtime-async `V2Methods.Quuux` in `ToString_Async`). This sets
`PublishReadyToRunStripILBodies` to `false` on those three test
projects, which #130360 already forwards through the
`_ApplePropertyNames` allowlist, leaving stripping on for every other
Apple mobile CoreCLR test app.

## Description
The Apple mobile CoreCLR library test apps are published as a composite
ReadyToRun image with IL bodies stripped, which the SDK turns on by
default for iOS-like runtime identifiers. A stripped body is replaced
with an invalid stub, so any test that needs the real IL at run time
fails. `System.Runtime.Loader.Tests`,
`System.Reflection.DispatchProxy.Tests`, and
`System.Xml.XmlSerializer.ReflectionOnly.Tests` load assemblies into
collectible `AssemblyLoadContext` instances, which cannot use the R2R
native code and recompile from IL, so they throw
`InvalidProgramException`; `System.Reflection.Metadata.Tests` reads a
stripped method body directly and throws `BadImageFormatException`.
The on-Helix AOT build reads only the properties forwarded through the
`_ApplePropertyNames` allowlist in `tests.ioslike.targets`, so this
change adds `PublishReadyToRunStripILBodies` to that allowlist and sets
it to `false` on these four test projects, leaving stripping on for
every other Apple mobile CoreCLR test app.

This PR updates the Apple mobile (“ioslike”) CoreCLR library test publish pipeline to preserve IL bodies for a small set of test projects that require IL at runtime, by explicitly disabling ReadyToRun IL-body stripping and ensuring that setting is forwarded through the Helix proxy-project property allowlist.
Changes:

`PublishReadyToRunStripILBodies` to `false` on those three test
projects, which #130360 already forwards through the
`_ApplePropertyNames` allowlist, leaving stripping on for every other
Apple mobile CoreCLR test app.

2207811
…L at run time (#130360)
## Description
The Apple mobile CoreCLR library test apps are published as a composite
ReadyToRun image with IL bodies stripped, which the SDK turns on by
default for iOS-like runtime identifiers. A stripped body is replaced
with an invalid stub, so any test that needs the real IL at run time
fails. `System.Runtime.Loader.Tests`,
`System.Reflection.DispatchProxy.Tests`, and
`System.Xml.XmlSerializer.ReflectionOnly.Tests` load assemblies into
collectible `AssemblyLoadContext` instances, which cannot use the R2R
native code and recompile from IL, so they throw
`InvalidProgramException`; `System.Reflection.Metadata.Tests` reads a
stripped method body directly and throws `BadImageFormatException`.
The on-Helix AOT build reads only the properties forwarded through the
`_ApplePropertyNames` allowlist in `tests.ioslike.targets`, so this
change adds `PublishReadyToRunStripILBodies` to that allowlist and sets
it to `false` on these four test projects, leaving stripping on for
every other Apple mobile CoreCLR test app.

## Description
Follow-up to #130360. The SDK strips IL bodies from the Apple mobile
CoreCLR composite ReadyToRun image by default, replacing each body with
an invalid stub, so any test that needs the real IL at run time fails.
Three more projects hit this: `System.Runtime.Extensions.Tests`
(`AppDomainTests.ExecuteAssembly` invokes a stripped entry point,
`InvalidProgramException`), `System.IO.Hashing.Tests`
(`Crc64ParameterSet.ForwardCrc64.InitializeVectorized`, a `Vector128`
intrinsic fallback), and `System.Diagnostics.StackTrace.Tests` (the
runtime-async `V2Methods.Quuux` in `ToString_Async`). This sets
`PublishReadyToRunStripILBodies` to `false` on those three test
projects, which #130360 already forwards through the
`_ApplePropertyNames` allowlist, leaving stripping on for every other
Apple mobile CoreCLR test app.

Pull request overview
This PR updates the Apple mobile (“ioslike”) CoreCLR library test publish pipeline to preserve IL bodies for a small set of test projects that require IL at runtime, by explicitly disabling ReadyToRun IL-body stripping and ensuring that setting is forwarded through the Helix proxy-project property allowlist.
Changes:
  • Set PublishReadyToRunStripILBodies=false in four library test projects that need IL bodies at runtime.
  • Add PublishReadyToRunStripILBodies to the _ApplePropertyNames allowlist in eng/testing/tests.ioslike.targets so the Helix AOT/proxy build sees the project-level setting.
