# Anchor v0.29 → v0.30 Codemod Automated migration tool for upgrading Solana Anchor projects from v0.29 to v0.30. Built with [ast-grep](https://ast-grep.github.io/) (sg/jssg engine) + Codemod workflow. Submitted to the [Boring AI Hackathon](https://dorahacks.io/hackathon/boring-ai/detail) on DoraHacks. ## Quick Start ```bash # Install ast-grep (jssg engine) cargo install ast-grep # Navigate to your Anchor 0.29 project cd /path/to/your-anchor-project # Preview changes (dry run) sg scan --config /path/to/anchor-029-to-030-codemod/sgconfig.yml . # Apply changes sg scan --apply --config /path/to/anchor-029-to-030-codemod/sgconfig.yml . # Migrate all Cargo.toml files under current directory (safe mode) # No-arg mode: uses `rg` when installed; otherwise uses `find` (skips ./target and ./.git) # Safe mode default: does NOT force `idl-build` feature on anchor-lang bash /path/to/anchor-029-to-030-codemod/migrate-cargo.sh # Or migrate one specific Cargo.toml bash /path/to/anchor-029-to-030-codemod/migrate-cargo.sh programs/your-program/Cargo.toml # Optional aggressive mode: force add `idl-build` on anchor-lang bash /path/to/anchor-029-to-030-codemod/migrate-cargo.sh --with-idl-build programs/your-program/Cargo.toml # Format after migration cargo fmt --all ``` **Version note:** this codemod upgrades on-chain crates to **`anchor-lang` / `anchor-spl` `0.30.1`**, which matches the commonly installed **`anchor-cli 0.30.1`** patch line and avoids patch-mismatch warnings. ## Migration Coverage Covers all **23 breaking changes** from the official Anchor **0.30.0** changelog (release notes); `migrate-cargo.sh` pins **`anchor-lang` / `anchor-spl` `0.30.1`** to match common `anchor-cli 0.30.1` installs: ### Automation Boundary (for evaluation) | Layer | What it handles | Evaluation claim | |------|------------------|------------------| | Deterministic rules/scripts | Well-scoped mechanical rewrites only | **Primary automation claim** (safety first) | | AI step | Edge cases, project-specific cleanup, semantic decisions | Coverage extension, not counted as deterministic fix | | Manual follow-up | Rare repo-specific dependency/build reconciliation | Explicitly tracked in validation notes | Current practical claim: - **Deterministic auto-fix:** 6 high-confidence migration classes - **AI-assisted coverage:** 11 classes - **Reminder/separate handling:** 6 classes - **Overall workflow automation target:** 80%+ with deterministic + AI pipeline ### Auto-fixed (6 items) | Change | Rule / Script | |--------|--------------| | `ctx.bumps.get("x").unwrap()` → `.copied()` | `anchor-bumps-option-type.yml` | | `AnchorProvider(conn, wallet, {})` → 2 args | `anchor-ts-provider-init.yml` | | `new Program(idl, programId[/PROGRAM_ID][, provider])` migration | `anchor-ts-program-id-arg-*` (4 scoped Program rules) | | `anchor-lang = "0.29.x"` → `0.30.1` (optional `--with-idl-build`) | `migrate-cargo.sh` | | `anchor-spl = "0.29.x"` → `0.30.1` | `migrate-cargo.sh` | | Remove `idl-parse` / `seeds` features + add `overflow-checks` | `migrate-cargo.sh` | ### Marked for AI review (11 items) | Change | Rule / Handler | |--------|---------------| | `anchor_spl::shared_memory` removed | `anchor-remove-shared-memory.yml` (TODO) | | `CLOSED_ACCOUNT_DISCRIMINATOR` removed | `anchor-remove-closed-account-discriminator.yml` (warning) | | `anchor_syn::idl` → `anchor_lang_idl` imports | `anchor-idl-import-path.yml` (TODO) | | Optional account bump types `u8` → `Option<u8>` | AI step | | IDL enums `#[non_exhaustive]` | AI step | | `accounts()` no longer accepts resolvable accounts | `anchor-ts-auto-accounts-system-program`, `anchor-ts-auto-accounts-clock`, `anchor-ts-auto-accounts-rent`, `anchor-ts-auto-accounts-token-program` | | camelCase method names | AI step | | Remove discriminator functions | AI step | | Remove `associated` / `associatedAddress` methods | AI step | | Remove `anchor-deprecated-state` feature | AI step | | `anchor-syn` features removed | AI step | ### Zero-FP Guardrails - `Program` constructor rewrite is now **strictly scoped** to explicit `programId`/`PROGRAM_ID` forms (2-arg and 3-arg with provider); it does not rewrite arbitrary argument forms. - `.accounts()` migration rules are scoped to explicit `.accounts({...})` calls only; non-`.accounts()` object arguments are ignored. - Cargo feature cleanup only edits `anchor-lang` / `anchor-syn` dependency lines (no global string replacement across unrelated crates). ### CLI reminders (4 items) | Change | Handler | |--------|---------| | `build-bpf` → `build-sbf` | AI step prompt | | `idl upgrade` closes buffer | AI step prompt | | Remove `--jest` option | AI step prompt | | Solana upgraded to 1.18.8 | AI step prompt | ### Separate codemod (2 items) | Change | Handler | |--------|---------| | IDL v0 → v1 schema migration | Tracked as separate codemod | | `anchor-syn` idl-parse/seeds removal | AI step + Cargo.toml sed (anchor-lang/anchor-syn lines) | ## Project Structure ``` anchor-029-to-030-codemod/ ├── codemod.yaml # Codemod Registry package metadata ├── workflow.yaml # workflow: 多段 YAML ast-grep（rules/*.yml）→ Cargo 脚本 → AI → fmt ├── sgconfig.yml # ast-grep root config: ruleDirs → rules/ ├── migrate-cargo.sh # Cargo.toml dependency migration script ├── CLAUDE.md # AI-readable project documentation ├── 需求文档.md # Chinese requirements document ├── README.md # This file │ ├── rules/ # ast-grep YAML rules (5 files, 13 rules) │ ├── anchor-bumps-option-type.yml │ ├── anchor-idl-import-path.yml │ ├── anchor-remove-shared-memory.yml │ ├── anchor-remove-closed-account-discriminator.yml │ └── anchor-ts-provider-init.yml # 9 rules: provider, 4 Program variants, 4 auto-accounts variants │ └── test-fixtures/ # Test fixtures for rule validation ├── old_program.rs # Rust 0.29 patterns └── old_program.ts # TypeScript 0.29 patterns + false-positive tests ``` ## Testing ### Synthetic fixtures ```bash export PATH="$HOME/.cargo/bin:$PATH" # Scan Rust fixtures sg scan --config sgconfig.yml test-fixtures/old_program.rs # Scan TypeScript fixtures sg scan --config sgconfig.yml test-fixtures/old_program.ts ``` ### Real-world projects (validated) | Project | Git | Dry-run | Apply | Build | Notes | |---------|-----|---------|-------|-------|-------| | Anchor official `v0.29.0` (framework mono-repo) | https://github.com/solana-foundation/anchor/tree/v0.29.0 | PASS | PASS | FAIL | Workflow works, but this repo is Anchor framework source (not a typical target program repo), so build failures are not used as codemod success criteria. | | `solana-presale-smart-contract` | https://github.com/rustjesty/solana-presale-smart-contract | PASS | PASS | PASS (`anchor build --no-idl`) | Required post-migration dependency cleanup in target repo: remove hard-pinned legacy deps and align to Anchor 0.30 dependency graph. | Validation date: `2026-05-01 (UTC+8)` Command shape used in both real repos: ```bash ROOT="$(pwd)" npx codemod workflow run -w /path/to/anchor-029-to-030-codemod/workflow.yaml \ -t "$ROOT" --param "target=$ROOT" \ --dry-run --no-interactive --allow-dirty --allow-fs --allow-child-process ``` ### Local verification in this repository Verified in this repo (2026-04-30): - `npx codemod workflow validate -w workflow.yaml` passed - `npx codemod workflow run -w workflow.yaml -t <fixture> --param target=<fixture> --dry-run` passed (ast-grep steps + workflow wiring) - `sg scan --config sgconfig.yml test-fixtures/old_program.rs` matched expected Rust patterns - `sg scan --config sgconfig.yml test-fixtures/old_program.ts` matched expected TypeScript patterns For reproducible real-repo evidence recording, use local template: `REAL_WORLD_VALIDATION_TEMPLATE.md`. ### Safety vs Coverage Modes - **Safe mode (default script behavior):** prioritizes lower false-positive risk; does not force `idl-build`. - **Coverage mode (workflow default):** `workflow.yaml` runs `migrate-cargo.sh --with-idl-build` to align with Anchor 0.30 breaking requirement around IDL build. ## Using the Full Workflow If you have the Codemod CLI installed: ```bash npx codemod workflow validate -w workflow.yaml npx codemod workflow run -w workflow.yaml -t /path/to/anchor-project --param target=/path/to/anchor-project --dry-run npx codemod workflow run -w workflow.yaml -t /path/to/anchor-project --param target=/path/to/anchor-project ``` Notes: - **YAML `ast-grep` steps** expect `config_file` to point at **rule YAML** (each rule has a top-level `id`). That is what lives under `rules/`. Do not point `config_file` at `sgconfig.yml` (that file uses `ruleDirs` and will fail Codemod parsing with `missing field id`). - **Shell steps** (`migrate-cargo.sh`, `cargo fmt`) run with the host working directory, not `-t`. Pass the same Anchor repo path for `-t` and `--param target=...` so Cargo steps execute inside the project being migrated. ## Hackathon - **Category**: Production-grade Migration Recipes (XL tier) - **Pre-approved**: Anchor v0.29 → v0.30 Rust API changes — Changelog - **Coverage**: 23/23 breaking changes mapped (6 deterministic auto-fix + 11 AI-assisted + 6 reminders/separate handling) - **False-positive policy**: deterministic rules are intentionally narrow; zero-FP target applies to deterministic transforms (AI/manual layer handles ambiguous cases) ### Evaluator Notes - Deterministic transforms are intentionally conservative to minimize false positives on real repositories. - Ambiguous or project-specific migration cases are explicitly delegated to the AI/manual layer instead of risky auto-rewrites. - Workflow execution is reproducible on real open-source repos with documented dry-run/apply/build evidence. - Safety-first defaults are provided for scripts, while workflow mode enables stronger breaking-change coverage when required. ## License MIT
