Upgraded GoogleTest to 1.13.0 + C++14

Changes

Revised the versions used for GoogleTest:

By default, upgraded to 1.13.0, which requires C++14
Still using 1.12.1 (unchanged) for CI builds that requires C++11

 if [ "x$GOOGLETEST_VERSION" = "x" ]; then
-  export GOOGLETEST_VERSION=1.12.1
+  export GOOGLETEST_VERSION=1.10.0


Why is default version changed to 1.10.0, can it remain as 1.12.1 ?

If GoogleTest version is not set on CI Pipeline, it was set as 1.10.0 by default. It could not be 1.12.1 version because GCC 4.8 oldish environment to support C++14.

lalitb · 2023-04-24T03:49:52Z

Can you update the description for the changes. As the latest version doesn't support C++11, how are we handling now CI tests for C++11 ?

@cngzhnp - I think this will break the builds for users who are building library (along with tests) using gcc4.8 (or any C++11 only compiler) ? Do you think we should revisit upgrade to googletest once we drop C++11 only compiler support in #1830.

Yes, you are right. However, it is like CI/CD pipeline design problem for opentelemetry-cpp. There are a lot of scripts which setup different versions of third party libraries or submodules etc. All of them are not in one page.

From my perspective, if we still want to support GCC 4.8 version with C++11 standard, we need a better CMake/CI-CD/Script design for this. Otherwise, like me people might only focus on passing the CI tests but not the real usecases.

This sets C++20 for all builds using tests, which breaks gcc4.8.

See related comment, to set C++14 is relevant ci/do_ci.sh targets instead.

Thanks for the PR, looking into this.

In the mean time, please merge the main branch into this PR, to resolve the conflicts.

cngzhnp · 2023-07-04T15:09:52Z

@marcalff Could you please verify the changes after your comments? Also, could you please take a look that why CodeQL build is failed, I am not sure that fail is directly related to my changes?

marcalff · 2023-07-10T10:01:52Z

@cngzhnp Thanks for the cleanup.

Remaining points below.

CodeQL

The CodeQL / CodeQL-Build build fails on:

  [  0%] Building CXX object api/test/core/CMakeFiles/version_test.dir/version_test.cc.o

    270 | #error C++ versions less than C++14 are not supported.
        |  ^~~~~

To fix this and keep the build in C++11, add:

GOOGLETEST_VERSION: 1.12.1

in file codeql-analysis.yml

setup-cmake.sh

Per previous comments, this code:

# This variable not set on CI pipeline for only legacy environment(GCC 4.8).
# With 1.13.0 version, C++14 must be set which does not supported by legacy environment anymore.
# Also with this version, release version path needs to be adapted.
if [ -z "${GOOGLETEST_VERSION}" ]; then
  # By default, GoogleTest version set the following version.
  export GOOGLETEST_VERSION=1.13.0
  GOOGLETEST_VERSION_PATH="v${GOOGLETEST_VERSION}"
  GOOGLETEST_FOLDER_PATH="googletest-${GOOGLETEST_VERSION}"
else
  GOOGLETEST_VERSION_PATH="release-${GOOGLETEST_VERSION}"
  GOOGLETEST_FOLDER_PATH="googletest-release-${GOOGLETEST_VERSION}"

fi

should decouple setting the default release with the release format.

Something like:

if [ -z "${GOOGLETEST_VERSION}" ]; then
  # Version by default. Requires C++14
  export GOOGLETEST_VERSION=1.13.0
fi

followed by something like:

if [  << GOOGLETEST_VERSION greater or equal to 1.13.0 >> ]; then
  GOOGLETEST_VERSION_PATH="v${GOOGLETEST_VERSION}"
  GOOGLETEST_FOLDER_PATH="googletest-${GOOGLETEST_VERSION}"
else
  GOOGLETEST_VERSION_PATH="release-${GOOGLETEST_VERSION}"
  GOOGLETEST_FOLDER_PATH="googletest-release-${GOOGLETEST_VERSION}"
fi

Expectation is that all the following use case works

unset GOOGLETEST_VERSION
setup_cmake

installs 1.13.0

GOOGLETEST_VERSION=1.13.0
setup_cmake

installs 1.13.0

GOOGLETEST_VERSION=1.12.1
setup_cmake

installs 1.12.1

GOOGLETEST_VERSION=1.10.0
setup_cmake

installs 1.10.0

@marcalff Could you please check & verify what I changed so for? Now, I fixed the CodeQL and split up GoogleTest version and its path.

@marcalff Could you please check & verify what I changed so for? Now, I fixed the CodeQL and split up GoogleTest version and its path.

Thanks.

How about this instead:

OLD_VERSION_REGEXP="^1\.([0-9]|10|11|12)(\..*)?$"

if [[ ${GOOGLETEST_VERSION} =~ ${OLD_VERSION_REGEXP} ]]; then
  # Old package name
else
  # New (starting with 1.13.0) package name
fi

marcalff · 2023-07-10T15:38:36Z

Somehow, adding quotes broke the regexp test.

Tested locally, this works:

if [[ ${GOOGLETEST_VERSION} =~ ${OLD_VERSION_REGEXP} ]]; then

Tested locally, this fails:

if [[ "${GOOGLETEST_VERSION}" =~ "${OLD_VERSION_REGEXP}" ]]; then

breaking the build for 1.10.0 (Gcc 4.8) and 1.12.1 (C++11 builds)

The code LGTM.

Please revise:

the PR description
code comments

for cleanup.

@owent

This change may cause merge collisions with your work, when setting CMAKE_CXX_STANDARD. I assume these will be trivial to fix, so not an issue.

@lalitb @esigo @owent

Please take a second look.

owent

LGTM and thanks.

@lalitb @esigo @owent

Please take a second look.

It's fine by me , we also use gtest 13 and a high CMAKE_CXX_STANDARD in some of our products.While for the users still use gcc 4.8 and C++11, them can still use gtest 1.10.0 and it works well now.
