# Defects4C SWE-bench-style export
One instance per repository and fixing commit, joined from the local Defects4C
export. `all` includes projects, legacy projects_v1, and additional cached
commits. `projects` restricts to projects/. Duplicate metadata is retained in
bug_metadata_json. Cached-only instances use the first parent as base_commit.
The single test split is an organizational choice, not a validated benchmark
split. No repository-disjoint training partition is claimed.
## Load
```python
from datasets import load_dataset
ds = load_dataset("json", data_files="data/all.jsonl", split="train")
# Once this folder is uploaded to a Hugging Face dataset repository:
# ds = load_dataset("YOUR_NAME/DATASET_NAME", "projects", split="test")
```
## Fields and limitations
Core fields follow the [SWE-bench dataset structure](https://www.swebench.com/SWE-bench/guides/datasets/).
`base_commit` is the buggy revision; `head_commit` is the fixed revision.
`patch` contains changes outside the recorded test-file list; `test_patch`
contains changes to that list; `full_patch` contains both. The test-file list
is metadata, not an independently validated exhaustive classification.
Cached-only rows have no classification: their patch contains all changes.
`patch_source=local_git` and `patch_is_exact=true` mean a binary-capable diff
was generated directly between the two Git commits. API patches are reconstructed
text hunks and are **not guaranteed complete or applyable**: mode changes,
binary data, truncated hunks, or API file pagination may be absent. Known
missing file hunks are recorded in omitted_patch_files and flagged
cached_api_partial; other cached patches are cached_api_unverified. Missing
patches or base mismatches remain explicit. Empty patches do not imply no fix.
`problem_statement` uses a neutral repair request and the original diagnostic;
it does not insert the fixing commit message or gold code. The original errors
may be runtime/test output rather than compiler errors. No upstream issue text
is invented. `original_errors` preserves distinct messages; `commit_message`
and cached repair records are reference material that can leak the solution.
`FAIL_TO_PASS` and `PASS_TO_PASS` are JSON-encoded empty lists because test
transitions were not measured. `test_outcomes_verified` is false, and `version`
is empty because package versions were not established. This dataset needs
repository-specific environments, test runners, and result parsers before it
can be scored by the SWE-bench harness. Build success is not test validation.
`build_command` is provided for projects/ rows supported by checkout_build.py.
Legacy and cached-only rows retain available templates/configuration but have
no claimed runnable build command. `build_artifacts_json` includes existing
pre/post build scripts, logs, and summaries; no new builds are performed during
export. `build_templates_json` retains project and shared Jinja templates.
Fields ending in `_json`, plus original_errors, source_files, test_files,
omitted_patch_files and the test-transition fields, are JSON strings; decode
them with json.loads. This preserves heterogeneous source schemas in Arrow.
Other availability fields are booleans and all remaining columns are strings.
`source_data.tar.gz` preserves the complete original data/, projects/, and
projects_v1/ inputs and reproduction/export scripts, including unjoined records.
Cached source snapshots retain their original provenance; no revision identity
is asserted beyond the source record. checksums.json contains file SHA-256 sums.
## Coverage
```json
{
"instances": 365,
"repositories": 44,
"collections": {
"projects": 119,
"projects_v1": 241,
"cached_only": 5
},
"patch_sources": {
"cached_api_unverified": 295,
"cached_api_partial": 67,
"local_git": 2,
"missing": 1
},
"with_original_error": 362,
"with_build_artifacts": 2,
"verified_test_outcomes": 0
}
```
## Reproduce
From the original export (or after extracting source_data.tar.gz):
```sh
python3 export_hf_dataset.py --output /path/to/new/dataset
```
The exporter uses the Python standard library and performs no downloads. Put
existing builds under build/PROJECT/COMMIT/ before exporting to include their
artifacts and derive exact patches from their Git objects. Use a new destination
for each export. The archive does not include cloned repositories or binaries.
The JSONL files and this card use the [Hugging Face repository layout](https://huggingface.co/docs/datasets/repository_structure).
Upload this directory as a dataset repository to publish it. No upload is
performed by the exporter.
## Licensing
This export does not assign a new license to upstream code or cached content.
Each project's original license and attribution requirements continue to apply.
The source export does not establish a single dataset-wide redistribution license.
