Dataset Banner

A curated dataset of breaking changes, compiler/runtime diagnostics, unified codemod patch diffs, and verification suites covering **Python, TypeScript/JavaScript, and Go**. Specifically engineered for training automated code repair models, AST codemod engines, DevSecOps agents, and software migration copilots. Each record represents an end-to-end migration lifecycle: $$\text{Deprecated Code} \longrightarrow \text{Compiler/Runtime Error} \longrightarrow \text{Architectural Reasoning} \longrightarrow \text{Unified Codemod Diff} \longrightarrow \text{Verification Test}$$ --- ## Dataset Splits & Commercial Licensing | Split | Records | Format | Primary Use Case | License | | :--- | :--- | :--- | :--- | :--- | | **Community Evaluation** (This Repo) | 250 | Parquet | Benchmarking, zero-shot evaluation, academic research | **CC BY-NC 4.0** | | **Enterprise Commercial Corpus** | 2,500 | Parquet + JSONL | Full fine-tuning (SFT/LoRA/DPO), proprietary copilot integration | **Commercial Enterprise License** | ### Complete Enterprise Package (2,500 Records) For commercial model fine-tuning, automated pull-request bot deployment, or integrating AST refactoring tools without non-commercial restrictions: 👉 **[Purchase Enterprise Commercial License via Dodo Payments](https://checkout.dodopayments.com/buy/pdt_0Nr7oeLBUeikL9WKxpLvI)** * **Instant Automated Delivery:** Immediate access to `enterprise_api_migrations_v1.parquet` and `.jsonl`. * **Perpetual Commercial Grant:** Complete indemnity for model training, weights redistribution, and commercial SaaS deployment. --- ## Dataset Schema Each entry contains 9 structured fields: ```json { "migration_id": "MIG-2026-SQLALCHEMY-9112", "ecosystem": "Python", "package_name": "sqlalchemy", "breaking_version_transition": "1.4.x -> 2.0.x", "deprecated_code_snippet": "from sqlalchemy import Column, Integer, String\n\nclass User(Base):\n __tablename__ = 'users'\n id = Column(Integer, primary_key=True)\n name = Column(String)", "runtime_error_or_warning": "DeprecationWarning: The Column class is deprecated and will be removed in a future version.

migration trace (e.g., `MIG-2026-NEXT-4174`). | | `ecosystem` | `string` | Primary runtime ecosystem and programming language (`Python`, `TypeScript`, `Go`). | | `package_name` | `string` | Specific upstream library, framework, or runtime undergoing migration (e.g., `next`, `react`, `sqlalchemy`, `pydantic`, `gin`, `vite`, `aws-sdk-go-v2`). | | `breaking_version_transition` | `string` | Version boundary introducing breaking changes (e.g., `13.x (Pages) -> 14.x/15.x (App Router)`, `18.x -> 19.x`, `1.4.x -> 2.0.x`). | | `deprecated_code_snippet` | `string` | Complete, executable source code snippet relying on legacy APIs, obsolete decorators, or deprecated patterns. | | `runtime_error_or_warning` | `string` | The exact compiler error, TypeScript diagnostic, or runtime deprecation warning emitted under the modern version. | | `migration_reasoning` | `string` | Structural root-cause analysis detailing why the upstream API broke and outlining the AST refactoring strategy. | | `codemod_patch_diff` | `string` | Minimal, unified git patch diff (`--- a/`, `+++ b/`, `@@ ... @@`) transforming deprecated patterns into modern idioms. | | `verification_test` | `string` | Executable unit test verifying that the migrated code runs cleanly on the modern runtime environment. | --- ### Core Migration Taxonomies Covered * **Next.js (`13.x Pages` -> `14.x/15.x App Router`)** * Replacing `pages/api` routes with standard `export async function POST(req: Request)` route handlers. * Migrating `getStaticPaths` to `generateStaticParams`. * Replacing `getServerSideProps` and `getStaticProps` with React async Server Components and direct `fetch()`. * Replacing `next/head` with the unified `export const metadata` API. * Adding the mandatory `'use client'` directive to components consuming interactive hooks (`useState`, `useEffect`). * **React (`18.x` -> `19.x`)** * Simplifying Context usage from `` to direct ``. * Deprecating `React.forwardRef` in favor of standard component `ref` props. * Replacing `useFormState` (from `react-dom`) and `useOptimistic` with the unified `useActionState` hook. * Eliminating legacy component lifecycle methods (`UNSAFE_componentWillMount`) and string refs in favor of `constructor` / `componentDidMount` and `createRef`. * **Python Pydantic (`1.10.x` -> `2.x`)** * Migrating legacy `@root_validator` and `@validator` decorators to `@model_validator(mode='before'|'after')` and `@field_validator`. * Refactoring inner `class Config` configurations to `model_config = ConfigDict(...)`. * Replacing deprecated serialization methods `.dict()` and `.json()` with `.model_dump()` and `.model_dump_json()`. * Moving from `GenericModel` to direct `BaseModel` generic parameterization. * **SQLAlchemy (`1.4.x` -> `2.0.x`)** * Replacing legacy `Column()` definitions with typed `Mapped[T]` and `mapped_column()` declarative mappings. * Replacing the legacy ORM query interface (`session.query(Model).filter(...)`) with 2.0 executable queries (`session.scalars(select(Model).where(...))`). * Removing `sessionmaker(autocommit=True)` to enforce explicit transaction management with `session.commit()`. * Enforcing explicit `text('SELECT ...')` constructs instead of passing raw string queries to `.execute()`. * Migrating model base classes from `declarative_base()` factory calls to subclassing `DeclarativeBase` directly. * **Go Standard Library & Generics (`Go 1.17` -> `Go 1.18+`)** * Replacing custom interface type switches and `interface{}` sorting with `constraints.Ordered` type parameters. * Replacing reflection-based map key loops with the generic `maps.Keys(m)` function. * Using the `golang.org/x/exp/slices` / `slices` package for generic containment and sorting operations. * Migrating generic storage containers from `interface{}` casting to parametric types (`Container[T any]`). * **Go Gin Engine (`v1.8.x` -> `v1.9.x+`)** * Requiring `ctx := c.Copy()` before spawning background goroutines to prevent memory corruption from recycled context pools. * Enforcing explicit `c.Next()` continuation or `c.AbortWithStatus(...)` termination in middleware. * Requiring `engine.SetTrustedProxies(...)` to mitigate IP spoofing when calling `c.ClientIP()`. * Updating struct tags to comply with strict `binding.Validator` v10 structural JSON validation rules. * **TypeScript Tooling & Bundlers (`Vite 4` -> `5`, `Rollup 4`, `Axios 0.27` -> `1.x`)** * Updating Rollup 4 plugin hooks (`resolveId`, `transform`) from synchronous return values to async promises returning `{ id }` or `{ code, map }` objects. * Removing the leading tilde prefix (`~`) in Sass/Less `@import` paths in favor of direct module imports or configured path aliases. * Changing `worker.format` defaults from `'iife'` to `'es'`. * Updating Axios imports from default imports to named/ESM-compatible exports (`import { Axios } from 'axios'`). * Migrating Axios proxy configurations from `{ host, port, auth }` objects to full URL strings. * **AWS SDK for Go (`v1.x` -> `v2.x`)** * Enforcing mandatory `context.Context` parameters as the first argument in all client SDK calls (`svc.ListBuckets(ctx, ...)` instead of `svc.ListBuckets(nil)`). * Moving primitive pointer helpers (`aws.String`, `aws.Int64`) to the `aws-sdk-go-v2/aws` module path. * Migrating client instantiation to `config.LoadDefaultConfig(ctx)` and `s3.NewFromConfig(cfg)`. --- ## Quickstart ```python from datasets import load_dataset #Load Community Evaluation Split dataset =
