History

Tony Liao fe535930d3 Bump minimum C++ version to C++17 after branch cut for v29. Branch cut for v29 is done on 2024-09-30: https://github.com/protocolbuffers/protobuf/releases/tag/v29.0-rc1 The next version v30 will be a breaking release. The release date is scheduled after the EOL of C++14 support on 2024-12-15 for Google open source projects generally: https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md This commit allows us to start taking advantage of C++17 features now. Some issues I ran into while upgrading: Two GCC 9.5 bugs related to -Wunused-but-set-parameter: - https://godbolt.org/z/qo51cKe7b - https://godbolt.org/z/65qW3vGhP Another GCC warning related to -Wself-assign in a template. There is a custom ASAN check that is not yet open sourced. I'll see if I can open source them in a subsequent commit. #test-continuous PiperOrigin-RevId: 687435042		1 month ago

README.md

This directory contains CI-specific tooling.

Clang wrappers

CMake allows for compiler wrappers to be injected such as ccache, which intercepts compiler calls and short-circuits on cache-hits. This can be done by specifying CMAKE_C_COMPILER_LAUNCHER and CMAKE_CXX_COMPILER_LAUNCHER during CMake's configure step. Unfortunately, X-Code doesn't provide anything like this, so we use basic wrapper scripts to invoke ccache + clang.

Bazelrc files

In order to allow platform-specific .bazelrc flags during testing, we keep 3 different versions here along with a shared common.bazelrc that they all include. Our GHA infrastructure will select the appropriate file for any test and overwrite the default .bazelrc in our workspace, which is intended for development only.
