The property descriptors of `@backDeployed` properties aren't available on OSes prior to the "back deployed before" OS version, so the descriptors cannot be referenced by clients that may run against older versions of the library that defines the property. See https://github.com/apple/swift/pull/59214 for prior art. Resolves rdar://106517386

|
|
// At a high level, this test is designed to verify that use of declarations
|
|
// annotated with @backDeployed behave as expected when running a client binary
|
|
// on an older OS that does not have the back deployed APIs. The
|
|
// BackDeployHelper framework has a number of APIs that are available in the
|
|
// OSes identified by the "BackDeploy 1.0" availability macro and are back
|
|
// deployed before OSes identified "BackDeploy 2.0". Verification is performed
|
|
// the following way:
|
|
//
|
|
// 1. Build the helper framework with both BackDeploy 1.0 defined to an
|
|
// OS version before Swift ABI stability and 2.0 defined to an OS version
|
|
// after Swift ABI stability. Note that stradling ABI stability is not
|
|
// a necessary requirement of this test; it's just convenient to use OS
|
|
// versions that correspond to existing lit substitutions.
|
|
// 2. Build the client executable with a deployment target set to the same
|
|
// OS version as BackDeploy 2.0.
|
|
// 3. Run the client executable, verifying that the copies of the functions in
|
|
// the framework are used (verified by runtime logic using #dsohandle).
|
|
// 4. Build a new copy of the helper framework, this time with BackDeploy 2.0
|
|
// set to a distant future OS version.
|
|
// 5. Build a new copy of the client executable using the new framework and
|
|
// the deployment target set to the same OS version as BackDeploy 1.0.
|
|
// 6. Run the new executable, verifying with #dsohandle that client copies of
|
|
// the APIs are used.
|
|
// 7. Re-build the framework in place, this time stripping the definitions of
|
|
// the back deployed APIs entirely.
|
|
// 8. Re-run the unmodified executable, with the same expectations as in (6).
|
|
// However, this time we're also verifying that the executable can run even
|
|
// without the original API symbols present in the linked dylib.
|
|
//
|
|
|
|
// REQUIRES: executable_test
|
|
// REQUIRES: OS=macosx
|
|
|
|
// The deployment targets and availability versions hardcoded into this test
|
|
// aren't compatible with the environment of the back deployment CI bots.
