From 427684c39563a6b13423c1077b7215d4b356c152 Mon Sep 17 00:00:00 2001 From: Jaroslav Bachorik Date: Thu, 5 Feb 2026 10:35:50 +0100 Subject: [PATCH 01/31] Replace Gradle cpp plugins with custom buildSrc tasks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Eliminated fragile "parasite pattern" that relied on cpp-library/cpp-application plugins. These plugins had version parsing issues with newer compilers and JNI header detection problems. Created custom SimpleCppCompile/SimpleLinkShared/SimpleLinkExecutable task types that: - Directly invoke compilers without version string parsing - Explicitly specify JNI include paths from JAVA_HOME - Support parallel compilation for faster builds - Maintain all existing build configurations (release/debug/asan/tsan/fuzzer) Migrated modules: - ddprof-lib: Main profiler library - ddprof-lib/gtest: C++ unit tests - ddprof-lib/fuzz: Fuzzer targets - ddprof-lib/benchmarks: Benchmark executable - malloc-shim: Memory interceptor Code reduction: ~530 lines removed (parasite pattern, task disabling workarounds) Code addition: ~600 lines in buildSrc (clean, maintainable task types) Verified: assembleDebug, gtestDebug (127 tests passed), benchmarks build successful 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- CLAUDE.md | 17 + buildSrc/build.gradle | 12 + buildSrc/src/main/groovy/CompilerUtils.groovy | 220 ++++++++++++ .../src/main/groovy/SimpleCppCompile.groovy | 141 ++++++++ .../main/groovy/SimpleLinkExecutable.groovy | 110 ++++++ .../src/main/groovy/SimpleLinkShared.groovy | 112 ++++++ ddprof-lib/benchmarks/build.gradle | 103 +++--- ddprof-lib/build.gradle | 205 +++++------ ddprof-lib/fuzz/build.gradle | 340 ++++++++---------- ddprof-lib/gtest/build.gradle | 264 ++++++-------- malloc-shim/build.gradle | 74 +++- 11 files changed, 1064 insertions(+), 534 deletions(-) create mode 100644 buildSrc/build.gradle create mode 100644 buildSrc/src/main/groovy/CompilerUtils.groovy create mode 100644 buildSrc/src/main/groovy/SimpleCppCompile.groovy create mode 100644 buildSrc/src/main/groovy/SimpleLinkExecutable.groovy create mode 100644 buildSrc/src/main/groovy/SimpleLinkShared.groovy diff --git a/CLAUDE.md b/CLAUDE.md index 11dc420af..ae308e581 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -278,6 +278,23 @@ The profiler uses a sophisticated double-buffered storage system for call traces - **Symbol Processing**: Automatic debug symbol extraction for release builds - **Library Packaging**: Final JAR contains all platform-specific native libraries +### Custom Native Build Tasks (buildSrc) +The project uses custom Gradle task types in `buildSrc/` instead of Gradle's `cpp-library` and `cpp-application` plugins.

Task Registration (afterEvaluate) + +After project evaluation, the plugin: + +1. Validates that `testSourceDir` and `configurations` are set +2. Checks if Google Test is available (via `hasGtest` project property) +3. Creates the master `gtest` aggregation task +4. Filters configurations by current platform/architecture +5. For each matching, active configuration: + - Creates per-config aggregation task (`gtest{Config}`) + - Discovers all `.cpp` files in `testSourceDir` + - For each test file, creates compile, link, and execute tasks + - Wires up task dependencies + +### 3. Compiler and Linker Args + +The plugin adjusts compiler and linker arguments: + +**Compiler Args**: +- Removes `-DNDEBUG` if `enableAssertions = true` +- Ensures `-std=c++17` is used +- Adds `-D__musl__` on musl libc systems + +**Linker Args**: +- For release configs with `keepSymbols = true`, skips minimizing flags +- Adds Google Test libraries: `-lgtest`, `-lgtest_main`, `-lgmock`, `-gmock_main` +- Adds platform libraries: `-ldl`, `-lpthread`, `-lm` +- On Linux, adds `-lrt` +- On macOS, adds `-L{googleTestHome}/lib` or default Homebrew path + +### 4. Source Compilation + +Each test is compiled by combining: +- All `.cpp` files from `mainSourceDir` +- The single test `.cpp` file + +This creates a complete executable with both main library code and test code. + +## Integration with Other Projects + +### malloc-shim Example + +```groovy +// malloc-shim/build.gradle +apply plugin: GtestPlugin + +gtest { + testSourceDir = file('src/test/cpp') + mainSourceDir = file('src/main/cpp') + + includes = files( + 'src/main/cpp', + 'include' + ) + + configurations = [debug, release] +} +``` + +### Integration with Java Tests + +The `ddprof-test` module shows how to integrate C++ gtest tasks with Java test tasks: + +```groovy +buildConfigNames().each { + def testTask = tasks.findByName("test${it}") + def gtestTask = project(':ddprof-lib').tasks.findByName("gtest${it.capitalize()}") + if (testTask && gtestTask) { + testTask.dependsOn gtestTask + } +} +``` + +This ensures C++ unit tests run before Java integration tests. + +## Troubleshooting + +### Google Test Not Found + +If you see "WARNING: Google Test not found", check: + +1. **macOS**: Install via Homebrew: `brew install googletest` +2. **Linux**: Install development packages: `sudo apt-get install libgtest-dev libgmock-dev` +3.

This plugin automates the process of splitting debug information from production binaries, reducing deployed library size while maintaining separate debug files for debugging and symbolication. - -## Overview - -The plugin handles the complete workflow of debug symbol extraction: -- **Extracts** debug symbols using platform-specific tools -- **Links** debug information back to stripped binaries (Linux only) -- **Strips** production binaries to minimize size -- **Copies** both debug symbols and stripped libraries to target locations - -### Platform Support - -- **Linux**: Uses `objcopy` to extract symbols and add GNU debuglink, `strip` to remove symbols -- **macOS**: Uses `dsymutil` to create .dSYM bundles, `strip -S` to remove symbols - -### Size Reduction - -Typical results for native profiling libraries: -- Original library with embedded debug info: ~6.1 MB -- Stripped library for production: ~1.2 MB (80% reduction) -- Separate debug symbols file: ~6.1 MB - -## Usage - -### Basic Configuration - -```groovy -// Apply the plugin -apply plugin: DebugSymbolsPlugin - -// Call setupDebugExtraction after link task is created -buildConfigurations.each { config -> - def linkTask = tasks.register("linkLib${config.name.capitalize()}", SimpleLinkShared) { - // ... link configuration - } - - // Setup debug extraction for release builds - if (config.name == 'release') { - setupDebugExtraction(config, linkTask, "copyReleaseLibs") - } -} -``` - -The `setupDebugExtraction` method takes three parameters: -1. **config**: The build configuration object (must have `name == 'release'` and `active == true`) -2. **linkTask**: The link task that produces the library file -3. **copyTaskName**: Optional name of the copy task to wire dependencies into - -### Automatic Configuration - -The plugin automatically configures reasonable defaults: - -- **`libraryFile`**: Set from linkTask.outputFile -- **`debugOutputDir`**: `build/lib/main/${config.name}/${os}/${arch}/debug` -- **`strippedOutputDir`**: `build/lib/main/${config.name}/${os}/${arch}/stripped` -- **`libraryExtension`**: `'so'` on Linux, `'dylib'` on macOS -- **`libraryBaseName`**: `'libjavaProfiler'` - -### Advanced Configuration - -You can customize the extension before calling `setupDebugExtraction`: - -```groovy -// Apply plugin -apply plugin: DebugSymbolsPlugin - -// Configure debug symbols extraction -debugSymbols { - libraryBaseName = 'myLibrary' - skipExtraction = false // Set to true to disable extraction -} - -// Then call setupDebugExtraction as usual -``` - -## Configuration Properties - -### DebugSymbolsExtension Properties - -- **`libraryFile`** (RegularFileProperty): The linked library file to extract symbols from - - Automatically set from linkTask.outputFile - -- **`debugOutputDir`** (DirectoryProperty): Output directory for debug symbol files - - Linux: Creates `.debug` files (e.g., `libjavaProfiler.so.debug`) - - macOS: Creates `.dSYM` bundles (e.g., `libjavaProfiler.dylib.dSYM/`) - -- **`strippedOutputDir`** (DirectoryProperty): Output directory for stripped libraries - - Contains production-ready libraries with debug symbols removed - -- **`targetDir`** (DirectoryProperty): Optional target for copying final artifacts - - If set, both debug and stripped files are copied here - -- **`skipExtraction`** (Property): Skip extraction even if tools are available - - Default: `false` - - Can also be controlled via `-Pskip-debug-extraction=true` property - -- **`libraryExtension`** (Property): Library file extension without dot - - Default: `'so'` on Linux, `'dylib'` on macOS - -- **`libraryBaseName`** (Property): Base name of library without extension - - Default: `'libjavaProfiler'` - -- **`toolPaths`** (MapProperty): Custom tool paths - - Keys: `'objcopy'`, `'strip'`, `'dsymutil'` - - Use when tools are not in PATH - -## Generated Tasks - -For each release configuration, the plugin creates: - -### 1. extractDebugLib{Config} -**Description**: Extract debug symbols from the linked library - -**Linux**: -```bash -objcopy --only-keep-debug input.so output.so.debug -``` - -**macOS**: -```bash -dsymutil input.dylib -o output.dylib.dSYM -``` - -### 2. addDebugLinkLib{Config} (Linux only) -**Description**: Add GNU debuglink section to the original library - -This creates a link from the stripped library to its debug symbols file, allowing debuggers to automatically locate symbols. - -```bash -objcopy --add-gnu-debuglink=output.so.debug input.so -``` - -### 3. stripLib{Config} -**Description**: Strip debug symbols from the library - -Creates a copy of the library and strips debug information: - -**Linux**: -```bash -cp input.so stripped/output.so -strip --strip-debug stripped/output.so -``` - -**macOS**: -```bash -cp input.dylib stripped/output.dylib -strip -S stripped/output.dylib -``` - -### 4. copy{Config}DebugFiles -**Description**: Copy debug symbol files to target directory - -Copies `.debug` files (Linux) or `.dSYM` bundles (macOS) to the final artifact location. - -## Workflow - -The complete debug symbol extraction workflow: - -``` -linkLibRelease - ↓ -extractDebugLibRelease - ↓ -addDebugLinkLibRelease (Linux only) - ↓ -stripLibRelease - ↓ -copyReleaseLibs (wired via setupDebugExtraction) - ↑ - └─ copyReleaseDebugFiles -``` - -### Linux Workflow - -1. **Link**: Produce `libjavaProfiler.so` with full debug info (~6.1 MB) -2. **Extract**: Create `libjavaProfiler.so.debug` with only debug info -3. **Add Link**: Add `.gnu_debuglink` section to original library -4. **Strip**: Create `stripped/libjavaProfiler.so` (~1.2 MB) -5. **Copy**: Copy both stripped library and `.debug` file to target - -### macOS Workflow - -1. **Link**: Produce `libjavaProfiler.dylib` with full debug info (~6.1 MB) -2. **Extract**: Create `libjavaProfiler.dylib.dSYM/` bundle with debug info -3. **Strip**: Create `stripped/libjavaProfiler.dylib` (~1.2 MB) -4. **Copy**: Copy both stripped library and `.dSYM` bundle to target - -## Skip Conditions - -The plugin automatically skips debug extraction when: - -1. **Tools not available**: `objcopy`/`strip` (Linux) or `dsymutil`/`strip` (macOS) -2. **Property set**: `-Pskip-debug-extraction=true` -3. **Skip native**: `-Pskip-native=true` -4. **Non-release build**: Only processes configs with `name == 'release'` -5. **Inactive config**: Only processes configs with `active == true` -6. **Extension configured**: `debugSymbols.skipExtraction = true` - -When skipped, the original library with embedded debug info is used. - -## Tool Installation - -### Linux - -**Debian/Ubuntu**: -```bash -sudo apt-get install binutils -``` - -**RHEL/CentOS**: -```bash -sudo yum install binutils -``` - -**Arch Linux**: -```bash -sudo pacman -S binutils -``` - -### macOS - -**Xcode Command Line Tools**: -```bash -xcode-select --install -``` - -The tools (`dsymutil` and `strip`) are included with Xcode Command Line Tools. - -## Integration Examples - -### Integration with Copy Tasks - -The plugin automatically wires dependencies into the specified copy task: - -```groovy -if (config.name == 'release') { - setupDebugExtraction(config, linkTask, "copyReleaseLibs") -} -``` - -This makes `copyReleaseLibs` depend on: -- `stripLibRelease` (copies stripped library) -- `copyReleaseDebugFiles` (copies debug symbols) - -### Multiple Configurations - -```groovy -buildConfigurations.each { config -> - def linkTask = tasks.register("linkLib${config.name.capitalize()}", SimpleLinkShared) { - // ... configuration - } - - // Only for release builds - if (config.name == 'release' && config.active) { - setupDebugExtraction(config, linkTask, "copy${config.name.capitalize()}Libs") - } -} -``` - -### Custom Base Name - -```groovy -debugSymbols { - libraryBaseName = 'myprofilinglib' -} - -// Results in: -// - myprofilinglib.so / myprofilinglib.dylib -// - myprofilinglib.so.debug / myprofilinglib.dylib.dSYM -``` - -## Debugging - -### Verify Tool Availability - -**Linux**: -```bash -objcopy --version -strip --version -``` - -**macOS**: -```bash -dsymutil --version -strip --version -``` - -### Check Task Creation - -List all tasks to verify debug extraction tasks were created: - -```bash -./gradlew tasks --all | grep -i debug -``` - -Expected tasks: -- `extractDebugLibRelease` -- `addDebugLinkLibRelease` (Linux only) -- `stripLibRelease` -- `copyReleaseDebugFiles` - -### Inspect Generated Files - -**Linux**: -```bash -# Check stripped library size -ls -lh build/lib/main/release/.../stripped/libjavaProfiler.so - -# Check debug file exists -ls -lh build/lib/main/release/.../debug/libjavaProfiler.so.debug - -# Verify debuglink section -readelf -p .gnu_debuglink build/lib/main/release/.../stripped/libjavaProfiler.so -``` - -**macOS**: -```bash -# Check stripped library size -ls -lh build/lib/main/release/.../stripped/libjavaProfiler.dylib - -# Check dSYM bundle -ls -lh build/lib/main/release/.../debug/libjavaProfiler.dylib.dSYM/Contents/Resources/DWARF/ - -# Verify symbols -dsymutil -s build/lib/main/release/.../stripped/libjavaProfiler.dylib -``` - -## Troubleshooting - -### Tools Not Found - -**Error**: "dsymutil or strip not available" - -**Solution**: Install Xcode Command Line Tools (macOS) or binutils (Linux) - -### Debug Link Not Working (Linux) - -**Issue**: Debugger cannot find debug symbols - -**Solutions**: -1. Verify `.gnu_debuglink` section exists: `readelf -p .gnu_debuglink library.so` -2. Ensure `.debug` file is in same directory as stripped library -3. Check debug file has correct name (matches debuglink section) -4. Verify GDB searches correct paths: `(gdb) show debug-file-directory` - -### Stripped Library Still Large - -**Issue**: Stripped library is still several MB - -**Possible causes**: -1. Debug extraction was skipped - check for warnings in build log -2. Library has other non-debug data (relocation tables, symbols for dynamic linking) -3. On macOS, use `strip -S` (strips only debug) not `strip -x` (strips everything) - -### .dSYM Bundle Empty (macOS) - -**Issue**: .dSYM/Contents/Resources/DWARF/ directory is empty - -**Solutions**: -1. Verify original library was compiled with `-g` flag -2. Check dsymutil output for errors -3. Ensure original library hasn't been stripped before extraction -4. Try manual extraction: `dsymutil -o output.dSYM input.dylib` - -## Implementation Notes - -### GNU Debuglink - -On Linux, the plugin uses GNU debuglink to connect stripped binaries to debug files: - -1. Extract symbols: `objcopy --only-keep-debug input.so output.so.debug` -2. Add link section: `objcopy --add-gnu-debuglink=output.so.debug input.so` -3. Strip binary: `strip --strip-debug input.so` - -The debuglink section contains: -- Debug file name -- CRC32 checksum of debug file - -Debuggers (GDB, LLDB) automatically locate debug files using this information. - -### dSYM Bundles (macOS) - -On macOS, dsymutil creates a directory bundle structure: - -``` -libjavaProfiler.dylib.dSYM/ - Contents/ - Info.plist - Resources/ - DWARF/ - libjavaProfiler.dylib # Debug information -``` - -The bundle contains: -- DWARF debug information -- Symbol tables -- Source line mappings -- Type information - -### Strip Behavior - -**Linux `strip --strip-debug`**: -- Removes DWARF debug sections (.debug_*) -- Keeps symbol tables for dynamic linking -- Keeps relocation information -- Typical size: ~20% of original - -**macOS `strip -S`**: -- Removes debug symbols -- Keeps global symbols for linking -- Keeps relocation information -- Typical size: ~20% of original - -## See Also - -- `SimpleLinkShared.groovy` - Custom C++ linking task -- `buildSrc/README_GTEST_PLUGIN.md` - Google Test plugin documentation -- GNU binutils documentation: https://sourceware.org/binutils/docs/ -- DWARF Debugging Standard: http://dwarfstd.org/ -- Apple dSYM documentation: https://developer.apple.com/documentation/xcode/building-your-app-to-include-debugging-information diff --git a/buildSrc/README_GTEST_PLUGIN.md b/buildSrc/README_GTEST_PLUGIN.md deleted file mode 100644 index 7062deb21..000000000 --- a/buildSrc/README_GTEST_PLUGIN.md +++ /dev/null @@ -1,349 +0,0 @@ -# Google Test Gradle Plugin - -A reusable Gradle plugin for integrating Google Test C++ unit tests into Gradle builds.

-- **`testSourceDir`** (DirectoryProperty): Directory containing C++ test files (*.cpp) -- **`mainSourceDir`** (DirectoryProperty): Directory containing main C++ source files -- **`includes`** (ConfigurableFileCollection): Include paths for compilation -- **`configurations`** (ListProperty): Build configurations to test (e.g., debug, release) - -### Optional Properties - -- **`googleTestHome`** (DirectoryProperty): Google Test installation directory (macOS) -- **`enableAssertions`** (Property): Remove `-DNDEBUG` to enable assertions (default: true) -- **`keepSymbols`** (Property): Skip minimizing flags for release gtest builds (default: true) -- **`failFast`** (Property): Stop on first test failure (default: false) -- **`alwaysRun`** (Property): Always re-run tests (default: false) -- **`gtestIncludePaths`** (MapProperty): Custom Google Test include paths per platform -- **`gtestLibPaths`** (MapProperty): Custom Google Test library paths per platform -- **`buildNativeLibs`** (Property): Build native test support libraries (Linux only, default: true) -- **`nativeLibsSourceDir`** (DirectoryProperty): Source directory for native test libraries -- **`nativeLibsOutputDir`** (DirectoryProperty): Output directory for built native test libraries - -## Generated Tasks - -### Per-Test Tasks - -For each test file `foo_ut.cpp` in each matching configuration: - -- **`compileGtest{Config}_{TestName}`**: Compile all main sources + test file - - Example: `compileGtestDebug_foo_ut` - - Uses SimpleCppCompile custom task - - Combines main sources and test file into single compilation unit - -- **`linkGtest{Config}_{TestName}`**: Link test executable with gtest libraries - - Example: `linkGtestDebug_foo_ut` - - Uses SimpleLinkExecutable custom task - - Links with gtest, gtest_main, gmock, gmock_main, and platform libs - -- **`gtest{Config}_{TestName}`**: Execute the test - - Example: `gtestDebug_foo_ut` - - Runs the compiled test executable - - Respects `failFast` and `alwaysRun` settings - -### Aggregation Tasks - -- **`gtest{Config}`**: Run all tests for a specific configuration - - Example: `gtestDebug`, `gtestRelease` - - Depends on all test execution tasks for that config - - Useful for running all debug or all release tests - -- **`gtest`**: Run all tests across all configurations - - Master aggregation task - - Depends on all test execution tasks across all matching configs - - Useful for comprehensive test runs - -### Support Tasks (Linux Only) - -- **`buildNativeLibs`**: Build native test support libraries - - Only created if `buildNativeLibs = true` - - Scans `nativeLibsSourceDir` for library source directories - - Executes `make` in each directory to build test libraries - - Test execution tasks depend on this if enabled - -## Platform Support - -The plugin automatically filters build configurations by platform: - -- **macOS**: Uses Homebrew Google Test by default (`/opt/homebrew/opt/googletest`) -- **Linux**: Links with system Google Test libraries and includes `-lrt` -- **musl libc**: Automatically adds `-D__musl__` compiler flag when detected - -Only configurations matching the current OS and architecture are processed. - -## How It Works - -### 1. Plugin Application - -When applied to a project, the plugin creates a `GtestExtension` configuration object accessible via the `gtest {}` block. - -### 2. Task Registration (afterEvaluate) - -After project evaluation, the plugin: - -1. Validates that `testSourceDir` and `configurations` are set -2. Checks if Google Test is available (via `hasGtest` project property) -3. Creates the master `gtest` aggregation task -4. Filters configurations by current platform/architecture -5. For each matching, active configuration: - - Creates per-config aggregation task (`gtest{Config}`) - - Discovers all `.cpp` files in `testSourceDir` - - For each test file, creates compile, link, and execute tasks - - Wires up task dependencies - -### 3. Compiler and Linker Args - -The plugin adjusts compiler and linker arguments: - -**Compiler Args**: -- Removes `-DNDEBUG` if `enableAssertions = true` -- Ensures `-std=c++17` is used -- Adds `-D__musl__` on musl libc systems - -**Linker Args**: -- For release configs with `keepSymbols = true`, skips minimizing flags -- Adds Google Test libraries: `-lgtest`, `-lgtest_main`, `-lgmock`, `-gmock_main` -- Adds platform libraries: `-ldl`, `-lpthread`, `-lm` -- On Linux, adds `-lrt` -- On macOS, adds `-L{googleTestHome}/lib` or default Homebrew path - -### 4. Source Compilation - -Each test is compiled by combining: -- All `.cpp` files from `mainSourceDir` -- The single test `.cpp` file - -This creates a complete executable with both main library code and test code. - -## Integration with Other Projects - -### malloc-shim Example - -```groovy -// malloc-shim/build.gradle -apply plugin: GtestPlugin - -gtest { - testSourceDir = file('src/test/cpp') - mainSourceDir = file('src/main/cpp') - - includes = files( - 'src/main/cpp', - 'include' - ) - - configurations = [debug, release] -} -``` - -### Integration with Java Tests - -The `ddprof-test` module shows how to integrate C++ gtest tasks with Java test tasks: - -```groovy -buildConfigNames().each { - def testTask = tasks.findByName("test${it}") - def gtestTask = project(':ddprof-lib').tasks.findByName("gtest${it.capitalize()}") - if (testTask && gtestTask) { - testTask.dependsOn gtestTask - } -} -``` - -This ensures C++ unit tests run before Java integration tests. - -## Troubleshooting - -### Google Test Not Found - -If you see "WARNING: Google Test not found", check: - -1. **macOS**: Install via Homebrew: `brew install googletest` -2. **Linux**: Install development packages: `sudo apt-get install libgtest-dev libgmock-dev` -3. Set `googleTestHome` to point to your installation -4. Verify `hasGtest` property is set correctly in your build - -### No Tasks Created - -If no tasks are created, check: - -1. `testSourceDir` is set and contains `.cpp` files -2. `configurations` is set and not empty -3. At least one configuration matches your current platform/arch -4. At least one configuration has `active = true` - -Enable debug logging by adding to your gradle.properties: -```properties -org.gradle.logging.level=debug -``` - -### Compilation Errors - -If compilation fails: - -1. Verify `includes` contains all necessary header paths -2. Check compiler args are appropriate for your platform -3. Ensure main source files compile independently -4. Review `compilerArgs` in your build configuration - -### Linking Errors - -If linking fails: - -1. Verify Google Test libraries are installed -2. Check `googleTestHome` or `gtestLibPaths` are correct -3. Ensure platform-specific libraries are available -4. Review linker args in your build configuration - -## Implementation Notes - -### SimpleCppCompile Integration - -The plugin uses the `SimpleCppCompile` task in simple mode: - -```groovy -sources = fileTree(mainSourceDir) { include '**/*.cpp' } + files(testFile) -``` - -This combines main sources and test file without using source sets, avoiding complexity and potential issues with source set instantiation. - -### Platform Detection - -The plugin uses `osIdentifier()` and `archIdentifier()` functions from `common.gradle` to match configurations: - -```groovy -def matches = (config.os == project.osIdentifier() && - config.arch == project.archIdentifier()) -``` - -This ensures tasks are only created for the current platform. - -### Task Dependencies - -Task dependencies flow as follows: - -``` -gtestDebug_foo_ut (Exec) - ↓ depends on -linkGtestDebug_foo_ut (SimpleLinkExecutable) - ↓ depends on -compileGtestDebug_foo_ut (SimpleCppCompile) -``` - -Aggregation tasks depend on all test execution tasks: - -``` -gtestDebug - ↓ depends on - gtestDebug_foo_ut, gtestDebug_bar_ut, ... - -gtest - ↓ depends on - gtestDebug_foo_ut, gtestRelease_foo_ut, ... -``` - -## Migration from ddprof-lib/gtest Module - -If you're migrating from the old `ddprof-lib/gtest` module: - -1. Remove `include ':ddprof-lib:gtest'` from `settings.gradle` -2. Remove `project(':ddprof-lib:gtest')` from dependencies -3. Apply `GtestPlugin` to your project -4. Configure the `gtest {}` block -5. Update task references from `project(':ddprof-lib:gtest')` to `project(':ddprof-lib')` -6. Delete the old `ddprof-lib/gtest` directory - -## Future Enhancements - -Potential future improvements: - -- **XML Reports**: Generate JUnit XML format test reports -- **Test Filtering**: Run only tests matching a pattern -- **Parallel Execution**: Run tests in parallel with configurable concurrency -- **Test Timeouts**: Automatically timeout hung tests -- **Custom Arguments**: Pass arguments to test executables -- **Test Discovery Patterns**: Support for subdirectories and custom file patterns - -## See Also - -- `SimpleCppCompile.groovy` - Custom C++ compilation task -- `SimpleLinkExecutable.groovy` - Custom C++ linking task -- `CompilerUtils.groovy` - Compiler detection utilities -- `common.gradle` - Build configuration definitions diff --git a/buildSrc/build.gradle b/buildSrc/build.gradle deleted file mode 100644 index b941b0c8b..000000000 --- a/buildSrc/build.gradle +++ /dev/null @@ -1,12 +0,0 @@ -plugins { - id 'groovy' -} - -repositories { - mavenCentral() -} - -dependencies { - implementation gradleApi() - implementation localGroovy() -} diff --git a/buildSrc/src/main/groovy/CompilerUtils.groovy b/buildSrc/src/main/groovy/CompilerUtils.groovy deleted file mode 100644 index 1bd10b8ef..000000000 --- a/buildSrc/src/main/groovy/CompilerUtils.groovy +++ /dev/null @@ -1,220 +0,0 @@ -/* - * Copyright 2026, Datadog, Inc. - * - * Licensed under the Apache License, Version 2.0 (the "License"); - * you may not use this file except in compliance with the License. - * You may obtain a copy of the License at - * - * http://www.apache.org/licenses/LICENSE-2.0 - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, - * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - * See the License for the specific language governing permissions and - * limitations under the License. - */ - -/** - * Utility class for compiler detection and configuration. - * Provides simple, reliable methods to find compilers without parsing version strings. - */ -class CompilerUtils { - - /** - * Find an available C++ compiler on the system PATH. - * Tries clang++ first (generally better error messages), then g++. - * - * @return The compiler executable name or full path - */ - static String findCxxCompiler() { - // Preference order: clang++ (better errors), then g++ - def candidates = ['clang++', 'g++', 'c++'] - - for (compiler in candidates) { - if (isCompilerAvailable(compiler)) { - return compiler - } - } - - // Default fallback - let it fail with a clear error if not found - return 'g++' - } - - /** - * Find an available C compiler on the system PATH. - * - * @return The compiler executable name or full path - */ - static String findCCompiler() { - def candidates = ['clang', 'gcc', 'cc'] - - for (compiler in candidates) { - if (isCompilerAvailable(compiler)) { - return compiler - } - } - - return 'gcc' - } - - /** - * Check if a compiler is available and executable. - * - * @param compiler The compiler name or path - * @return true if the compiler can be executed - */ - static boolean isCompilerAvailable(String compiler) { - try { - def proc = [compiler, '--version'].execute() - proc.waitForOrKill(5000) - return proc.exitValue() == 0 - } catch (Exception e) { - return false - } - } - - /** - * Get the system include directories for a compiler. - * Parses the output of `compiler -E -Wp,-v -xc++ /dev/null`. - * - * @param compiler The compiler to query - * @return List of system include directory paths - */ - static List getSystemIncludes(String compiler) { - try { - def nullDevice = System.getProperty('os.name').toLowerCase().contains('win') - ?

This plugin automates the process of splitting debug information from production - * binaries, reducing deployed library size while maintaining separate debug files for - * debugging and symbolication. - * - *

Supported platforms: - *

    - *
  • Linux: Uses objcopy to extract symbols and add GNU debuglink
    • - *
  • macOS: Uses dsymutil to create .dSYM bundles
    • - *
- * - *

The plugin creates the following task workflow: - * 

- * extractDebugSymbols → addDebugLink (Linux only) → stripLibrary → copyDebugFiles
- *
- * - *

Usage: - * 

- * apply plugin: DebugSymbolsPlugin

- * debugSymbols {

The plugin automatically: - *

    - *
  • Detects platform and selects appropriate tools
    • - *
  • Checks tool availability and warns if missing
    • - *
  • Skips extraction if tools are unavailable or explicitly disabled
    • - *
  • Creates platform-specific debug symbol files (.debug on Linux, .dSYM on macOS)
    • - *
  • Strips production libraries to minimize size
    • - *
  • Maintains GNU debuglink on Linux for symbol resolution

double-buffered storage system for call traces: +- **Active Storage**: Currently accepting new traces from profiling events +- **Standby Storage**: Background storage for JFR serialization and trace preservation +- **Instance-based Trace IDs**: 64-bit IDs combining instance ID (upper 32 bits) and slot (lower 32 bits) +- **Liveness Checkers**: Functions that determine which traces to preserve across storage swaps +- **Atomic Swapping**: Lock-free swap operations to minimize profiling overhead + +### JFR Integration Architecture +- **FlightRecorder**: Central JFR event recording and buffer management +- **Metadata Generation**: Dynamic JFR metadata for stack traces, methods, and classes +- **Constant Pools**: Efficient deduplication of strings, methods, and stack traces +- **Buffer Management**: Thread-local recording buffers with configurable flush thresholds + +### Native Integration Patterns +- **Signal Handler Safety**: Careful memory management in signal handler contexts + +### Multi-Engine Profiling System +- **CPU Profiling**: SIGPROF-based sampling with configurable intervals +- **Wall Clock**: SIGALRM-based sampling for blocking I/O and sleep detection +- **Allocation Profiling**: TLAB-based allocation tracking and sampling +- **Live Heap**: Object liveness tracking with weak references and GC integration + +## Critical Implementation Details + +### Thread Safety and Performance +- **Lock-free Hot Paths**: Signal handlers avoid blocking operations +- **Thread-local Buffers**: Per-thread recording buffers minimize contention +- **Atomic Operations**: Instance ID management and counter updates use atomics +- **Memory Allocation**: Minimize malloc() in hot paths, use pre-allocated containers + +### 64-bit Trace ID System +- **Collision Avoidance**: Instance-based IDs prevent collisions across storage swaps +- **JFR Compatibility**: 64-bit IDs work with JFR constant pool indices +- **Stability**: Trace IDs remain stable during liveness preservation +- **Performance**: Bit-packing approach avoids atomic operations in hot paths + +### Platform-Specific Handling +- **musl libc Detection**: Automatic detection and symbol resolution adjustments +- **Architecture Support**: x64, arm64 with architecture-specific stack walking +- **Debug Symbol Handling**: Split debug information for production deployments + +## Development Guidelines + +### Code Organization Principles +- **Code Integration**: Datadog-specific extensions are integrated directly into base files (e.g., `stackWalker.h`) +- **External Dependencies**: Local code in `cpp/` + +### Performance Constraints +- **Algorithmic Complexity**: Use O(N) or better, max 256 elements for linear scans +- **Memory Fragmentation**: Minimize allocations to avoid malloc arena issues +- **Signal Handler Safety**: No blocking operations, mutex locks, or malloc() in handlers + +### Testing Strategy +- **Multi-configuration Testing**: Test across debug, release, ASan, and TSan builds +- **Cross-JDK Compatibility**: Test with Oracle JDK, OpenJDK, and OpenJ9 +- **Native-Java Integration**: Both C++ unit tests (gtest) and Java integration tests +- **Stress Testing**: JMH-based performance and stability testing + +### Debugging and Analysis +- **Debug Builds**: Use `buildDebug` for full symbols and debugging information +- **Sanitizer Builds**: ASan for memory errors, TSan for threading issues +- **Static Analysis**: `scanBuild` for additional code quality checks +- **Test Logging**: Use `TEST_LOG` macro for debug output in tests + +## Build System Architecture + +### Gradle Multi-project Structure +- **ddprof-lib**: Core profiler with native compilation +- **ddprof-test**: Integration and Java unit tests +- **ddprof-test-tracer**: Tracing context integration tests +- **ddprof-stresstest**: JMH performance benchmarks +- **malloc-shim**: Linux memory allocation interceptor + +### Native Compilation Pipeline +- **Platform Detection**: Automatic OS and architecture detection via `common.gradle` +- **Configuration Matrix**: Multiple build configs (release/debug/asan/tsan) per platform +- **Symbol Processing**: Automatic debug symbol extraction for release builds +- **Library Packaging**: Final JAR contains all platform-specific native libraries +- **Compiler Detection**: Auto-detects clang++ (preferred) or g++ (fallback); override with `-Pnative.forceCompiler` + +### Native Build Plugin (build-logic) +The project includes a Kotlin-based native build plugin (`build-logic/`) for type-safe C++ compilation: +- **Composite Build**: Independent Gradle project for build logic versioning +- **Type-Safe DSL**: Kotlin-based configuration with compile-time checking +- **Auto Task Generation**: Creates compile, link, and assemble tasks per configuration +- **Debug Symbol Extraction**: Automatic split debug info for release builds (69% size reduction) +- **Source Sets**: Per-directory compiler flags for legacy/third-party code +- **Symbol Visibility**: Linux version scripts and macOS exported symbols lists + +**See:** `build-logic/README.md` for full documentation + +### Custom Native Build Plugin (build-logic) +The project uses a custom Kotlin-based native build plugin in `build-logic/` instead of Gradle's `cpp-library` and `cpp-application` plugins. This is intentional: + +**Why not cpp-library/cpp-application plugins:** +- Gradle's native plugins parse compiler version strings which breaks with newer gcc/clang versions +- JNI header detection has issues with non-standard JAVA_HOME layouts +- Plugin maintainers are unresponsive to fixes +- The plugins use undocumented internals that change between Gradle versions + +**Plugin components (`com.datadoghq.native-build`):** +- `NativeCompileTask` - Parallel C++ compilation with source sets support +- `NativeLinkTask` - Links shared libraries (.so/.dylib) with symbol visibility +- `PlatformUtils` - Platform detection and compiler location + +**Plugin components (`com.datadoghq.gtest`):** +- `NativeLinkExecutableTask` - Links executables (for gtest) +- `GtestPlugin` - Google Test integration and task generation + +**Key principle:** Direct compiler invocation without version parsing. The tasks simply find `clang++` or `g++` on PATH and invoke them with the configured flags. + +#### Configuring Build Tasks + +All build tasks support industry-standard configuration options.

└── {os}-{arch}/ → final packaged libraries -``` - -## Core Architecture Components - -### Double-Buffered Call Trace Storage -The profiler uses a sophisticated double-buffered storage system for call traces: -- **Active Storage**: Currently accepting new traces from profiling events -- **Standby Storage**: Background storage for JFR serialization and trace preservation -- **Instance-based Trace IDs**: 64-bit IDs combining instance ID (upper 32 bits) and slot (lower 32 bits) -- **Liveness Checkers**: Functions that determine which traces to preserve across storage swaps -- **Atomic Swapping**: Lock-free swap operations to minimize profiling overhead - -### JFR Integration Architecture -- **FlightRecorder**: Central JFR event recording and buffer management -- **Metadata Generation**: Dynamic JFR metadata for stack traces, methods, and classes -- **Constant Pools**: Efficient deduplication of strings, methods, and stack traces -- **Buffer Management**: Thread-local recording buffers with configurable flush thresholds - -### Native Integration Patterns -- **Signal Handler Safety**: Careful memory management in signal handler contexts - -### Multi-Engine Profiling System -- **CPU Profiling**: SIGPROF-based sampling with configurable intervals -- **Wall Clock**: SIGALRM-based sampling for blocking I/O and sleep detection -- **Allocation Profiling**: TLAB-based allocation tracking and sampling -- **Live Heap**: Object liveness tracking with weak references and GC integration - -## Critical Implementation Details - -### Thread Safety and Performance -- **Lock-free Hot Paths**: Signal handlers avoid blocking operations -- **Thread-local Buffers**: Per-thread recording buffers minimize contention -- **Atomic Operations**: Instance ID management and counter updates use atomics -- **Memory Allocation**: Minimize malloc() in hot paths, use pre-allocated containers - -### 64-bit Trace ID System -- **Collision Avoidance**: Instance-based IDs prevent collisions across storage swaps -- **JFR Compatibility**: 64-bit IDs work with JFR constant pool indices -- **Stability**: Trace IDs remain stable during liveness preservation -- **Performance**: Bit-packing approach avoids atomic operations in hot paths - -### Platform-Specific Handling -- **musl libc Detection**: Automatic detection and symbol resolution adjustments -- **Architecture Support**: x64, arm64 with architecture-specific stack walking -- **Debug Symbol Handling**: Split debug information for production deployments - -## Development Guidelines - -### Code Organization Principles -- **Code Integration**: Datadog-specific extensions are integrated directly into base files (e.g., `stackWalker.h`) -- **External Dependencies**: Local code in `cpp/` - -### Performance Constraints -- **Algorithmic Complexity**: Use O(N) or better, max 256 elements for linear scans -- **Memory Fragmentation**: Minimize allocations to avoid malloc arena issues -- **Signal Handler Safety**: No blocking operations, mutex locks, or malloc() in handlers - -### Testing Strategy -- **Multi-configuration Testing**: Test across debug, release, ASan, and TSan builds -- **Cross-JDK Compatibility**: Test with Oracle JDK, OpenJDK, and OpenJ9 -- **Native-Java Integration**: Both C++ unit tests (gtest) and Java integration tests -- **Stress Testing**: JMH-based performance and stability testing - -### Debugging and Analysis -- **Debug Builds**: Use `buildDebug` for full symbols and debugging information -- **Sanitizer Builds**: ASan for memory errors, TSan for threading issues -- **Static Analysis**: `scanBuild` for additional code quality checks -- **Test Logging**: Use `TEST_LOG` macro for debug output in tests - -## Build System Architecture - -### Gradle Multi-project Structure -- **ddprof-lib**: Core profiler with native compilation -- **ddprof-test**: Integration and Java unit tests -- **ddprof-test-tracer**: Tracing context integration tests -- **ddprof-stresstest**: JMH performance benchmarks -- **malloc-shim**: Linux memory allocation interceptor - -### Native Compilation Pipeline -- **Platform Detection**: Automatic OS and architecture detection via `common.gradle` -- **Configuration Matrix**: Multiple build configs (release/debug/asan/tsan) per platform -- **Symbol Processing**: Automatic debug symbol extraction for release builds -- **Library Packaging**: Final JAR contains all platform-specific native libraries -- **Compiler Detection**: Auto-detects clang++ (preferred) or g++ (fallback); override with `-Pnative.forceCompiler` - -### Native Build Plugin (build-logic) -The project includes a Kotlin-based native build plugin (`build-logic/`) for type-safe C++ compilation: -- **Composite Build**: Independent Gradle project for build logic versioning -- **Type-Safe DSL**: Kotlin-based configuration with compile-time checking -- **Auto Task Generation**: Creates compile, link, and assemble tasks per configuration -- **Debug Symbol Extraction**: Automatic split debug info for release builds (69% size reduction) -- **Source Sets**: Per-directory compiler flags for legacy/third-party code -- **Symbol Visibility**: Linux version scripts and macOS exported symbols lists - -**See:** `build-logic/README.md` for full documentation - -### Custom Native Build Plugin (build-logic) -The project uses a custom Kotlin-based native build plugin in `build-logic/` instead of Gradle's `cpp-library` and `cpp-application` plugins. This is intentional: - -**Why not cpp-library/cpp-application plugins:** -- Gradle's native plugins parse compiler version strings which breaks with newer gcc/clang versions -- JNI header detection has issues with non-standard JAVA_HOME layouts -- Plugin maintainers are unresponsive to fixes -- The plugins use undocumented internals that change between Gradle versions - -**Plugin components (`com.datadoghq.native-build`):** -- `NativeCompileTask` - Parallel C++ compilation with source sets support -- `NativeLinkTask` - Links shared libraries (.so/.dylib) with symbol visibility -- `PlatformUtils` - Platform detection and compiler location - -**Plugin components (`com.datadoghq.gtest`):** -- `NativeLinkExecutableTask` - Links executables (for gtest) -- `GtestPlugin` - Google Test integration and task generation - -**Key principle:** Direct compiler invocation without version parsing. The tasks simply find `clang++` or `g++` on PATH and invoke them with the configured flags. - -#### Configuring Build Tasks - -All build tasks support industry-standard configuration options.

This is typically separate from the Gradle native build. + +**Basic configuration:** +```kotlin +plugins { + id("com.datadoghq.scanbuild") +} + +scanBuild { + // Directory containing Makefile (required) + makefileDir.set(layout.projectDirectory.dir("src/test/make")) + + // Where to output HTML reports + outputDir.set(layout.buildDirectory.dir("reports/scan-build")) + + // Clang analyzer to use + analyzer.set("/usr/bin/clang++") + + // Parallel make jobs + parallelJobs.set(4) + + // Make targets to build (default: ["all"]) + makeTargets.set(listOf("all")) +} +``` + +**Advanced configuration:** +```kotlin +scanBuild { + makefileDir.set(layout.projectDirectory.dir("src/test/make")) + outputDir.set(layout.buildDirectory.dir("reports/scan-build")) + + // Use specific clang version + analyzer.set("/usr/bin/clang++-15") + + // Increase parallelism for faster analysis + parallelJobs.set(Runtime.getRuntime().availableProcessors()) + + // Analyze multiple targets + makeTargets.set(listOf("library", "tests")) +} +``` + +**Example Makefile structure:** + +Create `src/test/make/Makefile`: +```makefile +# Compiler (will be intercepted by scan-build) +CXX = clang++ +CXXFLAGS = -std=c++17 -Wall -Wextra -I../../main/cpp + +# Source files +SOURCES = $(wildcard ../../main/cpp/*.cpp) +OBJECTS = $(SOURCES:.cpp=.o) + +# Targets +all: library + +library: $(OBJECTS) + $(CXX) -shared -o libjavaProfiler.so $(OBJECTS) + +%.o: %.cpp + $(CXX) $(CXXFLAGS) -c $< -o $@ + +clean: + rm -f $(OBJECTS) libjavaProfiler.so + +.PHONY: all clean +``` + +**Integration with CI:** +```kotlin +// Make scanBuild part of verification +tasks.named("check") { + dependsOn("scanBuild") +} +``` + +**Platform-specific configuration:** +```kotlin +import com.datadoghq.native.util.PlatformUtils +import com.datadoghq.native.model.Platform + +if (PlatformUtils.currentPlatform == Platform.LINUX) { + scanBuild { + makefileDir.set(layout.projectDirectory.dir("src/test/make")) + outputDir.set(layout.buildDirectory.dir("reports/scan-build")) + } +} +``` + +--- + +## Tips and Tricks + +### Performance Tips + +#### 1. Parallel Compilation +Gradle automatically parallelizes compilation at the file level. Each `.cpp` file compiles independently. + +```bash +# Use more parallel workers +./gradlew build --parallel --max-workers=8 +``` + +#### 2. Incremental Builds +The plugin tracks: +- Source file changes +- Header file changes (via `-MMD` dependency tracking) +- Compiler flag changes + +Only modified files recompile: +```bash +# First build +./gradlew assembleDebug # Compiles all files + +# Edit one file +vim src/main/cpp/profiler.cpp + +# Second build +./gradlew assembleDebug # Only recompiles profiler.cpp +``` + +#### 3. Build Faster During Development + +```bash +# Use debug config (no optimization) +./gradlew assembleDebug + +# Skip tests +./gradlew assembleDebug -Pskip-tests + +# Use clang++ (generally faster than g++) +./gradlew assembleDebug -Pnative.forceCompiler=clang++ +``` + +### Debugging Tips + +#### 1. Verbose Compiler Output + +```kotlin +tasks.withType { + doFirst { + println("Compiler: ${compiler.get()}") + println("Args: ${compilerArgs.get()}") + println("Sources: ${sources.files}") + } +} +``` + +#### 2. Inspect Generated Build Files + +```bash +# Debug symbols location +ls -lh build/lib/main/release/*/*/debug/ + +# Object files +ls -lh build/obj/main/release/ + +# Task dependency tree +./gradlew assembleRelease --dry-run +``` + +#### 3. Check Active Configurations + +```bash +# View all build tasks +./gradlew tasks --group=build + +# The plugin logs active configurations: +./gradlew assembleAll | grep "Active configurations" +``` + +#### 4. Validate Debug Symbol Extraction + +**Linux:** +```bash +# Check if symbols are stripped +nm build/lib/main/release/linux/x64/libjavaProfiler.so | wc -l + +# Verify debug link +readelf -p .gnu_debuglink build/lib/main/release/linux/x64/libjavaProfiler.so + +# Check debug file +file build/lib/main/release/linux/x64/debug/libjavaProfiler.so.debug +``` + +**macOS:** +```bash +# Check stripped library +nm -gU build/lib/main/release/macos/arm64/libjavaProfiler.dylib + +# Verify dSYM bundle +dwarfdump --uuid build/lib/main/release/macos/arm64/libjavaProfiler.dylib.dSYM +``` + +### Testing Tips + +#### 1. Run Specific Test + +```bash +# Run one test from specific config +./gradlew gtestDebug_test_callTraceStorage +``` + +#### 2. Test with Multiple Configurations + +```bash +# Run tests with sanitizers in parallel +./gradlew gtestDebug gtestAsan gtestTsan --parallel +``` + +#### 3. Investigate Test Failures + +```bash +# Enable detailed test output +./gradlew gtestDebug --info + +# Run specific test binary directly +./build/bin/gtest/debug_test_callTraceStorage/test_callTraceStorage +``` + +#### 4. Test Environment Variables + +ASan and TSan tests automatically set environment variables: +```kotlin +// In BuildConfiguration: +testEnvironment.put("ASAN_OPTIONS", "...") +testEnvironment.put("TSAN_OPTIONS", "...") + +// Add custom variables: +buildConfigurations { + named("debug") { + testEnvironment.put("LOG_LEVEL", "debug") + testEnvironment.put("TEST_DATA_DIR", "$projectDir/testdata") + } +} +``` + +### Static Analysis Tips + +#### 1. Reading scan-build Reports + +```bash +# Run analysis +./gradlew scanBuild + +# Open report in browser +open build/reports/scan-build/*/index.html + +# Reports are organized by bug type: +# - Dead store: Unused assignments +# - Memory leak: Leaked allocations +# - Null dereference: Potential null pointer access +# - Uninitialized value: Use of uninitialized variables +``` + +#### 2. Focus on High-Priority Issues + +scan-build categorizes bugs by severity. Start with: +1. **Logic errors** - Wrong behavior +2. **Memory errors** - Leaks, use-after-free +3. **Null pointer issues** - Crashes +4. **Dead code** - Optimization opportunities + +#### 3. Incremental Analysis + +```bash +# Analyze after significant changes +./gradlew scanBuild + +# Compare with previous run +diff -u old-report/index.html build/reports/scan-build/*/index.html +``` + +#### 4. Customize Analyzer Options + +```kotlin +scanBuild { + makefileDir.set(layout.projectDirectory.dir("src/test/make")) + outputDir.set(layout.buildDirectory.dir("reports/scan-build")) + + // Use latest clang for better analysis + analyzer.set("/usr/bin/clang++-15") + + // Faster analysis with more parallelism + parallelJobs.set(8) +} +``` + +#### 5. Integration with Code Review + +```bash +# Run in CI before merging +./gradlew scanBuild + +# Fail build on new issues (requires custom script) +if grep -q "bugs found" build/reports/scan-build/*/index.html; then + echo "Static analysis found issues" + exit 1 +fi +``` + +#### 6. Suppressing False Positives + +If scan-build reports false positives, add assertions in code: +```cpp +void processData(Data* data) { + // Tell analyzer this can't be null + assert(data != nullptr); + + // Now scan-build knows data is valid + data->process(); +} +``` + +#### 7. Combine with Other Tools + +```bash +# Static analysis + runtime sanitizers = comprehensive coverage +./gradlew scanBuild # Find logic errors +./gradlew gtestAsan # Find memory errors +./gradlew gtestTsan # Find race conditions +``` + +### CI/CD Tips + +#### 1. Minimal CI Build +```bash +# Quick validation build +./gradlew assembleRelease -Pskip-tests +``` + +#### 2. Full CI Build +```bash +# Build all configs and run all tests +./gradlew assembleAll gtest +``` + +#### 3. CI with Sanitizers +```bash +# Test memory safety in CI +./gradlew gtestAsan gtestTsan + +# These are conditionally skipped if libasan/libtsan not available +``` + +#### 4. CI with Static Analysis +```bash +# Run static analysis in CI (Linux only) +./gradlew scanBuild + +# Archive reports as CI artifacts +# GitHub Actions example: +# - name: Upload scan-build reports +# uses: actions/upload-artifact@v3 +# with: +# name: scan-build-reports +# path: build/reports/scan-build/ + +# GitLab CI example: +# artifacts: +# paths: +# - build/reports/scan-build/ +# when: always +``` + +#### 5. Comprehensive CI Pipeline +```bash +# Full verification pipeline +./gradlew clean \ + assembleAll \ + gtest \ + gtestAsan \ + gtestTsan \ + scanBuild + +# This covers: +# - Compilation for all configs +# - Unit tests +# - Memory safety (ASan) +# - Thread safety (TSan) +# - Static analysis (scan-build) +``` + +#### 6. Release Artifact Packaging +```bash +# Build release with extracted debug symbols +./gradlew assembleRelease + +# Package production library (stripped) +tar czf library.tar.gz \ + build/lib/main/release/linux/x64/libjavaProfiler.so + +# Package debug symbols separately +tar czf library-debug.tar.gz \ + build/lib/main/release/linux/x64/debug/ +``` + +### Platform-Specific Tips + +#### macOS: Homebrew Google Test +```bash +# Install Google Test +brew install googletest + +# Plugin auto-detects at: +# /opt/homebrew/opt/googletest (Apple Silicon) +# /usr/local/opt/googletest (Intel) +``` + +#### Linux: System Google Test +```bash +# Ubuntu/Debian +sudo apt-get install libgtest-dev libgmock-dev + +# Fedora/RHEL +sudo dnf install gtest-devel gmock-devel +``` + +#### musl libc Detection +The plugin automatically detects musl libc and adds `-D__musl__`: +```bash +# Check musl detection +./gradlew assembleRelease | grep __musl__ + +# Force musl detection (advanced) +./gradlew -Pnative.musl=true assembleRelease +``` + +#### Linux: scan-build Installation + +scan-build is typically available on Linux but needs separate installation: + +```bash +# Ubuntu/Debian - includes clang static analyzer +sudo apt-get install clang-tools + +# Fedora/RHEL +sudo dnf install clang-tools-extra + +# Arch Linux +sudo pacman -S clang + +# Verify installation +which scan-build +scan-build --version +``` + +**Common scan-build locations:** +- `/usr/bin/scan-build` (most distros) +- `/usr/lib/llvm-*/bin/scan-build` (Ubuntu with specific LLVM versions) + +If you have multiple clang versions: +```bash +# List available scan-build versions +ls /usr/lib/llvm-*/bin/scan-build + +# Use specific version in plugin +scanBuild { + analyzer.set("/usr/lib/llvm-15/bin/clang++") +} +``` + +--- + +## Troubleshooting + +### Compiler Not Found + +**Problem:** +``` +Could not find any suitable C++ compiler +``` + +**Solutions:** +1.
