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

And splits, naming:

Split	Description
`dev`	All collected data point
`test`	Manually verified data point
`train`	Rest data point from `dev` except `test`

The results of evaluation of various bug localization approaches can be found in Long Code Arena 🏟 leaderboard.

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:

from datasets import load_dataset

# Select a configuration from ["py", "java", "kt"]
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

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="repos.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
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 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:

Field	Description
`repo_owner`	Bug issue repository owner.
`repo_name`	Bug issue repository name.
`issue_url`	GitHub link to issue `https://github.com/{repo_owner}/{repo_name}/issues/{issue_id}`.
`pull_url`	GitHub link to pull request `https://github.com/{repo_owner}/{repo_name}/pull/{pull_id}`.
`comment_url`	GitHub link to comment with pull request to issue reference `https://github.com/{repo_owner}/{repo_name}/pull/{pull_id}#issuecomment-{comment_id}`.
`issue_title`	Issue title.
`issue_body`	Issue body.
`base_sha`	Pull request base SHA.
`head_sha`	Pull request head SHA.
`diff_url`	Pull request diff link between base and head SHA `https://github.com/{repo_owner}/{repo_name}/compare/{base_sha}...{head_sha}`.
`diff`	Pull request diff content.
`pull_create_at`	Data of pull request creation in format yyyy-mm-ddThh:mm:ssZ.
`repo_stars`	Number of repo stars.
`changed_files`*	List of changed files parsed from diff.
`repo_language`	Main programming language used in the repository.
`repo_languages`	All programming languages used in the repository.
`repo_license`	Licenses assigned to the repository.

* Excluding test files that do not contain bug causes, rather changed in order to add test for proving that bug is gone.

The metrics-related fields are:

Field	Description
`changed_files_exts`	Dict from changed files extension to count.
`changed_files_count`	Number of changed files.
`java_changed_files_count`	Number of changed `.java` files.
`kt_changed_files_count`	Number of changed `.kt` files.
`py_changed_files_count`	Number of changed `.py` files.
`code_changed_files_count`	Number of changed `.java`, `.kt` or `.py` files.
`repo_symbols_count`*	Number of symbols in repository.
`repo_tokens_count`*	Number of tokens** in files in repository.
`repo_lines_count`*	Number of lines in files in repository.
`repo_files_without_tests_count`*	Number of files in repository.
`changed_symbols_count`*	Number of symbols in changed lines in diff.
`changed_tokens_count`*	Number of tokens** in changed lines in diff.
`changed_lines_count`*	Number of changed lines in diff (including added and deleted).
`changed_files_without_tests_count`*	Number of files in diff.
`issue_symbols_count`*	Number of symbols in issue body.
`issue_words_count`*	Number of words in issue body (separated by space symbols).
`issue_tokens_count`*	Number of tokens** in issue body.
`issue_lines_count`*	Number of text lines in issue body (separated by \n).
`issue_links_count`	Number of links ([...](...)) presented in issue body.
`issue_code_blocks_count`	Number of code blocks (```...```) presented in issue body.

* Excluding test files that do not contain bug causes, rather changed in order to add test for proving that bug is gone.
** Using GPT-4 tokenizer via ticktoken.

Repositories data

The compressed repositories provided in section 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 or 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, so you may reuse them to access required repository data.
