# Enterprise API Breaking Changes & SDK Migration Diffs (Community Edition)
<p align="center">
<img src="./dataset_product_cover_1024.png" alt="Dataset Banner" width="700">
</p>
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:
$$\text{Deprecated Code} \longrightarrow \text{Compiler/Runtime Error} \longrightarrow \text{Architectural Reasoning} \longrightarrow \text{Unified Codemod Diff} \longrightarrow \text{Verification Test}$$

### Field Definitions
| Field | Type | Description |
| :--- | :--- | :--- |
| `migration_id` | `string` | Unique tracking identifier for the 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 `<Context.Provider value={x}>` to direct `<Context value={x}>`.
* 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)`.
