Infer Pulse Static Analysis Evaluation Dataset
Dataset Description
This dataset contains 523 C functions extracted from Meta's Infer static analyzer test suite, specifically the Pulse analyzer tests. It's designed for evaluating Large Language Models (LLMs) on static analysis tasks, particularly memory safety bug detection in C code.
Note: This is an evaluation-only dataset. All examples are provided in the test split.
Key Features
- 523 individual C functions with ground truth bug annotations
- 51 unique source files from Infer's test suite
- 5 bug categories: NULL pointer dereference, memory leak, use-after-free, uninitialized value, resource leak
- Smart anonymization: Function names preserve semantic meaning while removing evaluation hints (
_bad,_oksuffixes) - Multiple bugs per function: Some functions contain multiple bug types (2.5% of dataset)
- Realistic code: Actual test cases from a production static analyzer
Dataset Statistics
- Total examples: 523
- With bugs: 217 (41.5%)
- Safe (no bugs): 306 (58.5%)
- Unique source files: 51
Bug Category Distribution
| Category | Count | Percentage |
|---|---|---|
| safe | 306 | 58.5% |
| nullptr_dereference | 112 | 21.4% |
| other | 68 | 13.0% |
| memory_leak | 18 | 3.4% |
| uninitialized_value | 12 | 2.3% |
| use_after_free | 4 | 0.8% |
| resource_leak | 3 | 0.6% |
Dataset Structure
Each example contains:
- id: Unique identifier
- source_file: Original file in Infer test suite
- original_function_name: Original name from Infer tests
- anonymized_function_name: Name with hints removed (e.g.,
malloc_no_check_bad→malloc_no_check) - function_code: Complete C function code
- context: Unified context including:
- #include statements
- Struct, enum, and typedef definitions (with nested dependencies)
- Global variable declarations
- Dependency function implementations
- has_bug: Boolean indicating if function has bugs
- bug_types: List of bug types (NULLPTR_DEREFERENCE, MEMORY_LEAK, etc.)
- bug_line_offsets: Line numbers relative to function start
- bug_absolute_lines: Absolute line numbers in original file
- bug_severities: Bug severity levels
- bug_traces: Detailed trace information from Infer
- category: Primary bug category or "safe"
- requires_interprocedural: Whether analysis requires understanding function calls
- start_line/end_line: Location in original source file
Example
from datasets import load_dataset
dataset = load_dataset("YOUR_USERNAME/infer-pulse-eval")
# Get first test example
example = dataset['test'][0]
print(f"Function: {example['anonymized_function_name']}")
print(f"Has bug: {example['has_bug']}")
if example['has_bug']:
print(f"Bug types: {example['bug_types']}")
print(f"\nCode:\n{example['function_code']}")
Intended Use
This dataset is designed for:
- Evaluating LLMs on static analysis tasks
- Benchmarking bug detection capabilities
- Training models for code understanding
- Researching AI-assisted program analysis
Evaluation Protocol
Send the LLM:
- System prompt with bug type definitions and analysis rules
- User prompt with the
function_codeand thecontext(includes, types, globals, dependencies)
Expected LLM response format:
{
"has_bug": true|false,
"bugs": [
{
"type": "NULLPTR_DEREFERENCE",
"line": 3,
"explanation": "malloc can return NULL, dereferenced without check"
}
]
}
Compare against ground truth has_bug and bug_types fields.
Anonymization Strategy
Function names are "anonymized" by removing evaluation hints while preserving semantic meaning:
- Removed:
_bad,_ok,_good,_latentsuffixes,FP_,FN_prefixes - Preserved: Descriptive parts (e.g.,
malloc_no_check,use_after_free_simple)
This maintains realistic code analysis conditions without giving away answers.
