## Dataset Description

- **Homepage:** https://github.com/microsoft/CodeXGLUE/tree/main/Code-Code/Defect-detection

### Dataset Summary

CodeXGLUE Defect-detection dataset, available at https://github.com/microsoft/CodeXGLUE/tree/main/Code-Code/Defect-detection

Given a source code, the task is to identify whether it is an insecure code that may attack software systems, such as resource leaks, use-after-free vulnerabilities and DoS attack. We treat the task as binary classification (0/1), where 1 stands for insecure code and 0 for secure code.
The dataset we use comes from the paper Devign: Effective Vulnerability Identification by Learning Comprehensive Program Semantics via Graph Neural Networks. We combine all projects and split 80%/10%/10% for training/dev/test.

### Supported Tasks and Leaderboards

- `multi-class-classification`: The dataset can be used to train a model for detecting if code has a defect in it.

### Languages

- C **programming** language

## Dataset Structure

### Data Instances

An example of 'validation' looks as follows.
```
{
    "commit_id": "aa1530dec499f7525d2ccaa0e3a876dc8089ed1e", 
    "func": "static void filter_mirror_setup(NetFilterState *nf, Error **errp)\n{\n    MirrorState *s = FILTER_MIRROR(nf);\n    Chardev *chr;\n    chr = qemu_chr_find(s->outdev);\n    if (chr == NULL) {\n        error_set(errp, ERROR_CLASS_DEVICE_NOT_FOUND,\n                  \"Device '%s' not found\", s->outdev);\n    qemu_chr_fe_init(&s->chr_out, chr, errp);", 
    "id": 8, 
    "project": "qemu", 
    "target": true
}
```

### Data Fields

In the following each data field in go is explained for each config. The data fields are the same among all splits.

#### default

|field name| type |               description                |
|----------|------|------------------------------------------|
|id        |int32 | Index of the sample                      |
|func      |string| The source code                          |
|target    |bool  | 0 or 1 (vulnerability or not)            |
|project   |string| Original project that contains this code |
|commit_id |string| Commit identifier in the original project|
