| # dataset_v2 — CodeNet Java compile errors, source-name aware |
| |
| Status: **compiled corpus, unlabelled**. Published at |
| <https://huggingface.co/datasets/criyle/codenet-compile-errors-v2> (private |
| false). Do not mix it with `dataset_v1/`: v1 uses the old `Main.java` convention |
| and the 65-leaf v1 taxonomy; v2 has no labels yet. |
|
|
| ## Build |
|
|
| | Step | Command / source | |
| |---|---| |
| | Source | `iNeil77/CodeNet`, Java split | |
| | Filter | `status == "Compile Error"` (53,023 submissions) | |
| | Sandbox | `http://10.0.0.162:5050`, OpenJDK 21.0.12.1 | |
| | Compile | javac under the declared public top-level class name; `Main.java` fallback | |
| | Build | `uploader/04_build_dataset_v2.py` | |
| | Publish | `uploader/05_publish_v2.py --repo criyle/codenet-compile-errors-v2` | |
|
|
| ## Result |
|
|
| | Outcome | Rows | |
| |---|---:| |
| | Ingested `Compile Error` submissions | 53,023 | |
| | Compiled cleanly once named after the class (file-name artefacts) | **18,465** | |
| | Still failing (the corpus) | **34,555** | |
| | javac internal crashes (excluded) | 3 | |
| | Rows with no `error:` line | **0** | |
|
|
| The source-name fix is the main difference from v1: `s053550749`, for example, |
| was a `Class name mismatch with file name` row under `Main.java`; it compiles |
| cleanly as `MyClass.java` and is excluded here. Of the 12,208 v1 rows labelled |
| `Class name mismatch with file name`, **10,741 now compile cleanly** and **944 |
| still fail** under the declared name (132 of the remaining corpus rows are |
| multiple-public-class errors, where no single file name satisfies javac). |
|
|
| ## Corpus columns |
|
|
| `row_id, sid, submission_id, pid, problem_id, uid, user_id, date, date_iso, |
| source_name, code, compilemessage, compile_status, exit_code, javac_version, |
| category, label_status, taxonomy_version, session_id, session_6h, source, |
| original_status, code_size` |
| |
| - `category` is empty and `label_status=unlabelled`; `taxonomy_version=2.1`. |
| - `session_id` is a `(user, problem)` 2-hour session, computed over the **full** |
| Java split (accepted submissions included); `session_6h` is the 6-hour variant. |
| - 7,251 users, 1,747 problems, **20,567 sessions** (mean 1.68, max 28 rows), |
| 100% session coverage. |
| - Date range 2010-01-04 → 2020-10-01. |
|
|
| ## Harness bug found and fixed during the build |
|
|
| The stock `go_judge` client asks the sandbox to copy out `Main.class`. When a |
| clean submission declares only package-private classes (e.g. `class q2`) it |
| produces `q2.class`, and go-judge returns |
| `File Error: open Main.class: no such file` even though javac exited 0. The first |
| pass therefore classified **3,583 clean submissions as `compile_error`**. A |
| compile-only request with no `copyOutCached` rechecked those rows: **3,580 were |
| clean, 3 were real errors**. The final corpus has 0 rows without an `error:` line. |
| The three `An exception has occurred in the compiler (21.0.12.1)` rows are |
| excluded as `compiler_crash`. |
