🏟️ Long Code Arena (Commit Message Generation)

This is the benchmark for Commit Message Generation task as part of 🏟️ Long Code Arena benchmark.

How-to

Since the dataset is private, if you haven't used HF Hub before, add your token via huggingface-cli first:
```
huggingface-cli login
```
List all the available configs via datasets.get_dataset_config_names and choose an appropriate one

Load the data via load_dataset:

from datasets import load_dataset

configuration = "TODO"  # select a configuration
dataset = load_dataset("JetBrains-Research/lca-cmg", configuration, split="test")

Note that all the data we have is considered to be inthe test split.

Note. Working with git repositories under repos directory is not supported via 🤗 Datasets. Download and extract the contents of each repository. We provide a full list of files in paths.json.

Dataset Structure

This dataset contains three kinds of data:

full data about each commit (including modifications)
metadata with quality labels
compressed git repositories

Full data

This section concerns configuration with full data about each commit (no -labels suffix).

Each example has the following fields:

Field	Description
`repo`	Commit repository.
`hash`	Commit hash.
`date`	Commit date.
`license`	Commit repository's license.
`message`	Commit message.
`mods`	Modifications from commit (see below for details).

We consider two possible commit modifications formats:

lists of file diffs
full file sources before and after commit

Currently, only CommitChronicle is considered as an input source, so only the first commit modifications format is used.

List of diffs (CommitChronicle)

Data point example:

{'hash': 'b76ed0db81b3123ede5dc5e5f1bddf36336f3722',
 'repo': 'apache/libcloud',
 'date': '05.03.2022 17:52:34',
 'license': 'Apache License 2.0',
 'message': 'Add tests which verify that all OpenStack driver can be instantiated\nwith all the supported auth versions.\nNOTE: Those tests will fail right now due to the regressions being\nintroduced recently which breaks auth for some versions.',
 'mods': {'diff': [{'change_type': 'MODIFY',
    'new_path': 'libcloud/test/compute/test_openstack.py',
    'old_path': 'libcloud/test/compute/test_openstack.py',
    'diff': '@@ -39,6 +39,7 @@ from libcloud.utils.py3 import u\n<...>'}],
  'file_src': None}}

Labels

This section concerns configuration with metadata and labels (with -labels suffix).

Each example has the following fields:

Field	Description
`repo`	Commit repository.
`hash`	Commit hash.
`date`	Commit date.
`license`	Commit repository's license.
`message`	Commit message.
`label`	Label of current commit as a target for CMG task.
`comment`	Comment for a label for current commit (optional, might be empty).

Labels are in 1-5 scale, where:

1 – strong no
2 – weak no
3 – unsure
4 – weak yes
5 – strong yes

Data point example:

{'hash': '1559a4c686ddc2947fc3606e1c4279062cc9480f',
 'repo': 'appscale/gts',
 'date': '15.07.2018 21:00:39',
 'license': 'Apache License 2.0',
 'message': 'Add auto_id_policy and logs_path flags\n\nThese changes were introduced in the 1.7.5 SDK.',
 'label': 1,
 'comment': 'no way to know the version'}

Git Repositories

This section concerns repos directory, which stores compressed Git repositories for all the commits in this benchmark. After you download and extract it, you can work with each repository either via Git or via Python libraries like GitPython or PyDriller.
