| f927f23 | wiktorg | 29 April 2020, 12:44:57 UTC | Use custom type instead of alias for SecretUniquePtr This allows ensuring that non-empty SecretUniquePtr is always created with MakeSecretUniquePtr.

| f569639 | ckl | 29 April 2020, 01:13:22 UTC | Refine run_tests.sh to fix test execution in the Kokoro macos_external environment. run_tests.sh * Decouple protoc installation and Tink installation via pip. * Install protoc to a temporary directory, removing the need for superuser permissions to unzip an archive to a system folder with overwrite enabled. * During macos_external init, install the Python protobuf package via pip3. * Refactor to reduce code duplication and simplify Kokoro platform detection logic. * Provide a bit more environment context information in the logs. envelope_test.sh * Include the Google root certificates as a data dependency. On macos_external hosts, these aren't included on the system in a location where gRPC can find it. PiperOrigin-RevId: 308936419 | 29 April 2020, 01:13:59 UTC |
