| # SWE-DockerLess |
|
|
| A SWE-bench-shaped benchmark that needs **no Docker, no network and no prebuilt |
| image**. Every row carries its own repo snapshot, so an instance is reproduced by |
| writing files to a temp directory, `git init`, `git apply` and running pytest. |
|
|
| Rows are byte-for-byte SWE-bench compatible: same field names, same |
| `FAIL_TO_PASS` / `PASS_TO_PASS` JSON-string encoding, same "resolved" rule. One |
| extra `dockerless` object carries the snapshot and the test command. |
|
|
| ``` |
| SWE-DockerLess.jsonl 4 instances, 62.9 KiB (~16k tokens total) |
| build_dataset.py rebuilds the jsonl from repos/ + fixed/ + newtests/ and |
| derives F2P/P2P by actually running pytest |
| run_harness.py scoring harness (--gold, or --predictions preds.jsonl) |
| repos/ the four buggy base repos (the source of the snapshots) |
| fixed/ gold-fix versions of the touched files |
| newtests/ the tests that become test_patch |
| tools/validate.py schema, patch-application and budget checks |
| tools/make_controls.py generates empty / cross / partial negative controls |
| reports/ harness output for gold and the three controls |
| ``` |
|
|
| ## Instances |
|
|
| | instance_id | repo | the bug | F2P | P2P | gold patch | |
| | --- | --- | --- | --- | --- | --- | |
| | `swedl__miniconf-1` | swedl/miniconf | `${k}` interpolation recurses on cycles (no `CircularReferenceError`) and `$$` never escapes | 9 | 15 | 41 added lines | |
| | `swedl__ttlcache-1` | swedl/ttlcache | LRU order ignores reads and overwrites; `len()` counts expired rows | 5 | 12 | 12 added lines | |
| | `swedl__cronlite-1` | swedl/cronlite | `5/15` collapses to `{5}`; day-of-week `7` rejected | 8 | 21 | 11 added lines | |
| | `swedl__semverlite-1` | swedl/semverlite | prerelease ordering is lexicographic; prereleases satisfy release ranges | 7 | 19 | 23 added lines | |
| |
| 29 FAIL_TO_PASS tests, 67 PASS_TO_PASS tests. Difficulty is SWE-bench-like rather |
| than toy-like: each fix needs a behaviour change in a real algorithm (recursive |
| descent with cycle detection, an LRU invariant, cron field expansion, semver |
| precedence), and the hidden tests pin exact semantics — error message text, the |
| 0-6 weekday scale, the "prerelease must opt in" range rule — that a shallow |
| patch misses. The `partial` control below scores 5/9, 2/5, 6/8 and 3/7 F2P |
| without resolving a single instance. |
| |
| ## Row schema |
| |
| | field | notes | |
| | --- | --- | |
| | `instance_id` | `swedl__<repo>-1` | |
| | `repo` | `swedl/<repo>` | |
| | `base_commit` | real 40-char sha of the snapshot commit (deterministic) | |
| | `patch` | gold fix, `git diff` unified diff against `base_commit` | |
| | `test_patch` | adds test files only, never touches source | |
| | `problem_statement` | issue-style report; states the contract, never names a test | |
| | `hints_text` | `""` | |
| | `created_at`, `version` | `2026-10-30`, `1.0` | |
| | `environment_setup_commit` | equals `base_commit` | |
| | `FAIL_TO_PASS`, `PASS_TO_PASS` | JSON-encoded strings, as in SWE-bench | |
| | `dockerless.files` | `{path: content}` snapshot of the repo at `base_commit` | |
| | `dockerless.test_cmd` | `python -m pytest -v --tb=no -p no:cacheprovider {tests}` | |
| | `dockerless.test_files` | the node-id prefixes to run | |
| |
| ## Running it |
| |
| ```bash |
| python -m pip install pytest # the only dependency |
| python build_dataset.py # regenerate + re-verify the jsonl |
| python run_harness.py --gold # sanity check, expect 4/4 |
| python run_harness.py --predictions predictions/partial.jsonl --out reports/partial.json |
| ``` |
| |
| A predictions file is JSONL of `{"instance_id", "model_name_or_path", |
| "model_patch"}` — the SWE-bench format. `resolved` requires **all** F2P and |
| **all** P2P to pass. |
| |
| ## Verified results |
| |
| ``` |
| $ python run_harness.py --gold |
| instance resolved F2P P2P note |
| swedl__miniconf-1 yes 9/9 15/15 ok |
| swedl__ttlcache-1 yes 5/5 12/12 ok |
| swedl__cronlite-1 yes 8/8 21/21 ok |
| swedl__semverlite-1 yes 7/7 19/19 ok |
| resolved 4/4 (100.0%) in 10.3s |
| |
| $ python run_harness.py --predictions predictions/empty.jsonl -> 0/4 |
| $ python run_harness.py --predictions predictions/cross.jsonl -> 0/4 |
| $ python run_harness.py --predictions predictions/partial.jsonl -> 0/4 |
| ``` |
| |
| `build_dataset.py` is the ground truth for F2P/P2P: it materialises a clean |
| checkout, applies `test_patch`, runs pytest, applies `patch`, runs pytest again, |
| and classifies every test by observed outcome. It refuses to write a row if the |
| gold patch leaves any failure behind, if F2P is empty, or if a test disappears. |
| |
| ## Budget |
| |
| Measured for `max_tokens = 2048`, `context = 240000`: |
| |
| - prompt per instance: ~2.0k–2.6k tokens (problem statement + snapshot) |
| - gold patch: 11–41 added lines, ~200–700 tokens — comfortably inside 2048 |
| - whole dataset: ~16k tokens, so all four rows fit in one context if you want |
| |
| ## Deliberate deviations from SWE-bench |
| |
| - **Synthetic repos.** These are four purpose-built Python packages, not real |
| GitHub projects, so there is no `repo` clone step and no upstream history. |
| - **Snapshot in the row** instead of a Docker image. `base_commit` is a genuine |
| commit sha of that snapshot, so `git apply` and `git diff` behave normally. |
| - **No install step.** Packages are importable from the repo root, so |
| `dockerless.install` is empty and pytest runs with the repo as rootdir. |
| - **Python only**, single language, to keep the harness to `python + git + pytest`. |
