# LCA (Bug Localization)
This is the data for **Bug Localization** benchmark as part of LCA. 
The bug localization problem can be formulated as follows: given an issue with a bug description and a repository snapshot in a state where the bug is reproducible, identify the files within the repository that need to be modified to address the reported bug.

The dataset provides all required components for evaluation of bug localization approaches in real project-level large-scale data collected from GitHub, including:
* Bug issue description
* Repositories from which the content on the state of the commit SHA where the bug is reproducible can be extracted
* List of files that should be changed in order to solve the bug
* Other additional data and metrics, that can be useful in approach development

The collected dataset was carefully filtered, enhances with useful metrics and, what is more, manually labeled, which assures the data quality and provides a golden subset of good examples for evaluation.\
Moreover, the dataset was splitted into several categories, naming:

| **Category**   |  **Description**  |  **Number of data points**  |
|:------------------:|:----------------------------------------:|:----------------------------------------:|
| `py` | Only `.py` files in changes | 4,339 |
| `java` | Only `.java` files in changes | 2,522  | 
| 'kt'  | Only `.kt` files in changes | 618  |
| 'mixed' | At list one `.java`, `.py`, or `.kt` file in changes with any other changed files | 2,322 |

And splits, naming:
| **Split**   |  **Description**  |
|:------------------:|:----------------------------------------:|
| `dev` | All collected data point |
| `test` | Manually verified data point |
| `train` | Rest data point from `dev` except `test` | 

The following sections will describe the utilities around the dataset as well as detailed dataset content description.

## How-to

* Load the data via [`load_dataset`](https://huggingface.co/docs/datasets/v2.14.3/en/package_reference/loading_methods#datasets.load_dataset):

    ```py
    from datasets import load_dataset
    
    # Select a configuration from ["py", "java", "kt", "mixed"]
    configuration = "py"
    # Select a split from ["dev", "train", "test"]
    split = "dev"
    # Load data
    dataset = load_dataset("JetBrains-Research/lca-bug-localization", configuration, split=split)  
    ```

* Load repos via [`hf_hub_download`](https://huggingface.co/docs/huggingface_hub/v0.20.3/en/package_reference/file_download#huggingface_hub.hf_hub_download)
    ```py
    from huggingface_hub import hf_hub_download
    from datasets import load_dataset
    import zipfile
    import os
    
    # Load json with list of repos' .tar.gz file paths
    paths_json = load_dataset("JetBrains-Research/lca-bug-localization", data_files="paths.json")

    # Load each repo in .tar.gz format, unzip, delete archive
    repos = paths_json[configuration][0]
    repos_path = "path/to/repos"

    for i, repo_zip_path in enumerate(repos):
        repo_name = os.path.basename(repo_zip_path).split('.')[0]
        repo_path = os.path.join(repos_path, repo_name)

        # Load repo zip
        local_repo_zip_path = hf_hub_download(
            "JetBrains-Research/lca-bug-localization",
            filename=repo_zip_path,
            repo_type="dataset",
            local_dir="path/to/zips"
        )

        # Unzip repo
        with zipfile.ZipFile(local_repo_zip_path, 'r') as zip_ref:
            zip_ref.extractall(repo_path)
        os.remove(local_repo_zip_path)
   ```

* Data streaming by [HFDataSource](https://github.com/JetBrains-Research/lca-baselines/blob/main/bug_localization/src/baselines/data_sources/hf_data_source.py) \
  Besides data loading, `HFDataSource` returns data point for running baseline along with the content of the repository in the state the bug is reproducible (aka `base_sha` commit of the pull request which resloves the bug issue). \
  All source code for working with the GitHub history of repositories (commits, diffs, etc.) are available in [`git_utils.py`](https://github.com/JetBrains-Research/lca-baselines/blob/main/bug_localization/src/utils/git_utils.py) as so as example of baselines, utilizes this dataset.

### Bug localization data

Each data point contains main subset of field as well as additional metrics calculated upon them. \
The main fields are:

|    `repo_owner`    |            Bug issue repository owner.            |
|    `repo_name`    |            Bug issue repository name.            |
|    `issue_url`      |       GitHub link to issue <br> `https://github.com/{repo_owner}/{repo_name}/issues/{issue_id}`.       |
|    `pull_url`      |       GitHub link to pull request <br> `https://github.com/{repo_owner}/{repo_name}/pull/{pull_id}`.       |
|    `comment_url`      |       GitHub link to comment with pull request to issue reference <br> `https://github.com/{repo_owner}/{repo_name}/pull/{pull_id}#issuecomment-{comment_id}`.       |
|    `issue_title`       | Issue title.  |

### Repositories data
The compressed repositories provided in section [repos](https://huggingface.co/datasets/JetBrains-Research/lca-bug-localization/tree/main/repos) separately from data point to provide access to the various stages of repository, saving its initial structure, as well as to reuse one's content for different data point connected to the same repository.
To extract the required information from repositories, each zip file should be unarchived. Afterwords, we recommend to use [GitPython](https://github.com/gitpython-developers/GitPython) or [PyDriller](https://github.com/ishepard/pydriller) python library to navigate thought repository history and extract one's content on required commit or calculate diff. 
Most of the required utility methods are provided in our repository in [`git_utils.py`](https://github.com/JetBrains-Research/lca-baselines/blob/main/bug_localization/src/utils/git_utils.py), so you may reuse them to access required repository data.
