# ClickHouse Build Skill

Build ClickHouse in `build/${buildType}` directory (e.g., `build/Debug`, `build/ASAN`, `build/RelWithDebInfo`).

## Arguments

- `$0` (optional): Build type - one of: `Release`, `Debug`, `RelWithDebInfo`, `ASAN`, `TSAN`, `MSAN`, `UBSAN`. Default: `RelWithDebInfo`
- `$1` (optional): Target - specific target to build (e.g., `clickhouse-server`, `clickhouse-client`, `clickhouse`). Default: `clickhouse`
- `$2+` (optional): Additional cmake/ninja options

## Build Types

| Type | Description | CMake Flags |
|------|-------------|-------------|
| `Release` | Optimized production build | `-DCMAKE_BUILD_TYPE=Release` |
| `Debug` | Debug build with symbols | `-DCMAKE_BUILD_TYPE=Debug` |
| `RelWithDebInfo` | Optimized with debug info | `-DCMAKE_BUILD_TYPE=RelWithDebInfo` |
| `ASAN` | AddressSanitizer (memory errors) | `-DCMAKE_BUILD_TYPE=Debug -DSANITIZE=address` |
| `TSAN` | ThreadSanitizer (data races) | `-DCMAKE_BUILD_TYPE=Debug -DSANITIZE=thread` |
| `MSAN` | MemorySanitizer (uninitialized reads) | `-DCMAKE_BUILD_TYPE=Debug -DSANITIZE=memory` |
| `UBSAN` | UndefinedBehaviorSanitizer | `-DCMAKE_BUILD_TYPE=Debug -DSANITIZE=undefined` |

## Common Targets

- `clickhouse` - Main all-in-one binary
- `clickhouse-server` - Server component
- `clickhouse-client` - Client component
- `clickhouse-local` - Local query processor
- `clickhouse-benchmark` - Benchmarking tool

## Build Process

**IMPORTANT:** This skill assumes the build directory is already configured with CMake. Do NOT run `cmake` or create build directories - only run `ninja`.

1. **Determine build configuration:**
   - Build type: `$0` or `RelWithDebInfo` if not specified
   - Target: `$1` or `clickhouse` if not specified
   - Build directory: `build/${buildType}` (e.g., `build/RelWithDebInfo`, `build/Debug`, `build/ASAN`)

2. **Create log file and start the build:**

   **Step 2a: Create temporary log file first:**
   ```bash
   mktemp /tmp/build_clickhouse_XXXXXX.log
   ```
   - This will
