* ci: add -Dcoverage_tool=gcov|llvm option, wire native llvm-cov in matrix
introduces native llvm source-based coverage as an alternative to the
existing gcov + gcovr pipeline. driven by a new -Dcoverage_tool cache
variable (default 'gcov' for backwards compat; 'llvm' enables
-fprofile-instr-generate / -fcoverage-mapping + llvm-profdata + llvm-cov).
cmake:
- RippledSettings.cmake: add coverage_tool with validation
- RippledInterface.cmake: split coverage compile/link flags by tool
- RippledCov.cmake: dispatch to the new helper when tool=llvm
- CodeCoverageLLVM.cmake (new): setup_target_for_coverage_llvm() driving
profraw -> profdata -> export with format-aware output (lcov/json/txt/html)
ci:
- new clang-20 llvm-cov coverage matrix row (apt.llvm.org bootstrap for
clang >= 19 since 24.04 default repos cap at clang-18)
- conditional install of llvm-N vs gcovr based on coverage_tool
- artifact + codecov upload generalised to coverage.lcov | coverage.xml
- coverage cmake-args switched to *_FLAGS_DEBUG so the build action's
stdlib flag isn't clobbered
temp (revert before merging to dev):
- matrix narrowed to just the llvm-cov row on non-main refs so we can
iterate without burning runners
- 'coverage-llm' added to push trigger for direct-push CI runs
* ci: drop coverage-llm from push triggers, PR trigger covers it
* ci: actually narrow matrix to just the llvm-cov row
prior guard checked base_ref against ['dev','candidate','release'] which
excluded the very PR we're iterating on. drop the guard - this branch
is for iteration only and must be reverted before merging anyway.
* ci(deps): apply Wno-missing-template-arg-list workaround to Linux clang
grpc 1.50.1 hits -Werror=missing-template-arg-list-after-template-kw on
clang-19+. macOS clang already had this workaround in the conan profile;
mirror it to the Linux branch, gated on compiler==clang.
* ci(temp): disable all workflows except Nix GA on this branch
renames every non-nix workflow to .yml.disabled so they stop firing on
PR pushes while we iterate on the llvm-cov coverage row. MUST be
reverted before merging to dev.
* fix(cov): use absolute binary path in llvm-cov run command
bare 'rippled' wasn't on PATH and the build dir isn't '.', so the
profile-collection step failed with 'No such file or directory'.
splice the resolved absolute path back into Cov_EXECUTABLE before
the run command consumes it.
* ci(deps): replace hardcoded grpc workaround with matrix-driven conan_deps_cxxflags
new dependencies action input `conan_deps_cxxflags` (json list, default
'[]') drives `tools.build:cxxflags` in the conan profile. clearly named
to indicate the flags only apply to conan dependency builds, not the
rippled build itself.
removes the per-os/per-compiler hardcoded workaround (linux clang
conditional + unconditional macOS block) that used to set the same flag
in two places kept-in-sync by hand.
call sites:
- xahau-ga-nix.yml: clang-20 coverage row gets the
-Wno-missing-template-arg-list-after-template-kw workaround for grpc 1.50.1
- xahau-ga-macos.yml.disabled: same flag plumbed through (preserves
prior behaviour when re-enabled)
drop the workaround entries when grpc is bumped past the fix.
* fix(cov): tighten coverage_tool=llvm validation + macOS tool discovery
two bugs caught in review:
- RippledSettings.cmake: the clang-only guard for coverage_tool=llvm ran
before coverage_test could auto-enable coverage. so
'-Dcoverage_tool=llvm -Dcoverage_test=Foo' on a gcc build slipped past
the guard and produced an instrumentation/tool mismatch. move the
guard after the auto-enable block.
- CodeCoverageLLVM.cmake: _find_llvm_cov_tools unconditionally
preferred xcrun's tools on APPLE, which on a homebrew clang-N build
would pair the user's clang with xcode's llvm-cov - exactly the
version mismatch the helper is trying to avoid. gate the xcrun branch
on CMAKE_CXX_COMPILER_ID == AppleClang.
* chore(cov): drop dead BASE_DIRECTORY arg + revert .disabled file edit
- CodeCoverageLLVM.cmake: BASE_DIRECTORY was parsed but never used
(no analog to gcovr's -r in the llvm-cov commands we emit). dead arg.
- xahau-ga-macos.yml.disabled: revert the conan_deps_cxxflags addition.
the file is disabled so the edit was bit-rotting in unreachable code.
whoever revives the macOS workflow can wire up the field then.
* Revert "chore(cov): drop ... .disabled file edit" (partial)
restore the conan_deps_cxxflags addition to xahau-ga-macos.yml.disabled.
prior commit framed it as dead code, but the .disabled rename is itself
a TEMP measure being reverted before merge - the field is needed for the
macOS workflow to keep building grpc 1.50.1 once it's re-enabled, since
the unconditional workaround was removed from the dependencies action.
* fix(ci): restore conan_deps_cxxflags on macOS workflow
reverts part of f8a30c528d - removing this line dropped the apple-clang
grpc workaround that the dependencies action used to apply
unconditionally before the matrix-driven refactor. the .disabled rename
is itself a TEMP measure being reverted before merge, so the field needs
to be in place when the macOS workflow comes back.
* ci: restore matrix-row comments explaining clang-20 + grpc workaround
* ci: dedupe conan_deps_cxxflags in macOS workflow row
prior turn-of-events created two identical conan_deps_cxxflags entries
in the same matrix row from overlapping restore commits. keep one.
* ci: undisable workflows, drop gcc-13 coverage row, keep clang-20 llvm-cov as sole codecov reporter
- restore the 8 .yml.disabled workflows back to .yml
- drop the gcc-13 gcov coverage matrix row; native clang-20 llvm-cov is
now the only codecov reporter
- update minimal_matrix indices to match
- remove the TEMP narrowing block that filtered to just the llvm-cov row
- log line says '7 configs (build x6 + clang-20 llvm-cov coverage)' to
reflect the new shape
* fix(ci): scope conan_deps_cxxflags per Conan package pattern
prior shape (bare json list -> 'tools.build:cxxflags=[...]') leaked into
the consumer/rippled build via the conan-generated toolchain
(CMAKE_CXX_FLAGS_INIT). on macOS, where the build action doesn't
override CMAKE_CXX_FLAGS, this would silently apply the workaround flag
to rippled itself.
reshape the input to a json object keyed by Conan package pattern:
{"grpc/*":["-Wno-..."]}
action emits package-pattern scoped lines:
grpc/*:tools.build:cxxflags=["-Wno-..."]
flags only apply while building the matching dependency. consumer
toolchain stays clean. python validator rejects the consumer pattern
('&') and malformed shapes.
* ci: bump apt retries to 5 to handle ppa.launchpadcontent.net flakes
* ci: relax patch coverage for PeerImp
These are modules and sources that support our CMake build.
== FindBoost.cmake ==
In order to facilitate updating to latest releases of boost, we've made a local copy of the FindBoost cmake module in our repo. The latest official version can generally be obtained here.
The latest version provided by Kitware can be tailored for use with the version of CMake that it ships with (typically the next upcoming CMake release). As such, the latest version from the repository might not work perfectly with older versions of CMake - for instance, the latest version might use features or properties only available in the version of CMake that it ships with. Given this, it's best to test any updates to this module with a few different versions of cmake.
