This PR introduces automated code coverage reporting for valkey-search using Codecov and lcov, modeled after the Valkey core Codecov workflow.

Key Changes

  1. GitHub Actions Workflow (.github/workflows/codecov.yml):
    • Compiles debug binaries with coverage flags (--coverage for compiler and linker) inside the presubmit Docker container.
    • Runs Unit Tests and generates an isolated unittests.info trace.
    • Runs OSS Integration Tests and captures a cumulative combined.info trace.
    • Filters out third-party libraries, submodules, dependencies (/opt/*, /usr/*), and test harnesses to report metrics exclusively on src/ and vmsdk/src/.
    • Uploads traces via codecov/codecov-action@v5 with separate flags (unittests vs integration,combined).
  2. Codecov Configuration (codecov.yml):
    • Configures informational: true for both patch and project checks to provide visibility without blocking PR merges.

📝 Walkthrough

Walkthrough

Changes

The pull request adds automated coverage collection and Codecov reporting. It also adds debug build support, optional environment preparation, and configuration-aware artifact handling in the Ubuntu build script.

Coverage Reporting

Layer / File(s) Summary
Workflow triggers and test environment
.github/workflows/codecov.yml
The workflow defines triggers, concurrency cancellation, Docker image creation, and ccache restoration.
Coverage collection and artifact preparation
.github/workflows/codecov.yml
The container runs unit and integration tests with coverage flags. The workflow captures and filters lcov traces, resets permissions, and archives test results.
Codecov upload and reporting configuration
.github/workflows/codecov.yml, codecov.yml
The workflow uploads unit and combined traces. Codecov statuses are informational, comments use a condensed format, and GitHub Checks annotations are disabled.

Ubuntu Build Handling

Layer / File(s) Summary
Build configuration and output paths
ci/build_ubuntu.sh
The script defaults to release builds, accepts --debug, derives test output paths from BUILD_CONFIG, and copies available artifacts.
Build environment controls
ci/build_ubuntu.sh
The script supports --skip-prepare-env, adds the Benchmark CMake path, and conditionally configures core dumps.

50-53: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve argument boundaries when removing --skip-prepare-env.

BUILD_SH_ARGS is flattened into one string. ${BUILD_SH_ARGS/--skip-prepare-env/} removes the first matching substring, not the exact option. If an output path contains --skip-prepare-env, this can corrupt the path and forward the wrapper-only option to build.sh. Line 191 then reparses the result with word splitting.

Store arguments in a Bash array, remove the exact element, and invoke build.sh with "${BUILD_SH_ARGS[@]}".

Proposed fix
-BUILD_SH_ARGS=$@
+BUILD_SH_ARGS=("$@")

-        BUILD_SH_ARGS="${BUILD_SH_ARGS/--skip-prepare-env/}"
+        for i in "${!BUILD_SH_ARGS[@]}"; do
+            if [[ "${BUILD_SH_ARGS[$i]}" == "--skip-prepare-env" ]]; then
+                unset "BUILD_SH_ARGS[$i]"
+                break
+            fi
+        done
+        BUILD_SH_ARGS=("${BUILD_SH_ARGS[@]}")

-    (cd ${ROOT_DIR} && ./build.sh --test-errors-stdout ${BUILD_SH_ARGS})
+    (cd "${ROOT_DIR}" && ./build.sh --test-errors-stdout "${BUILD_SH_ARGS[@]}")
