Once a +contract is deployed, its storage schema cannot be updated in place. +Instead, the contract must be upgraded (via `env.deployer().update_current_contract_wasm`) +and the new code must handle both old and new storage layouts. + +## Strategies + +### 1. Lazy Migration (Recommended) + +Write the new data key alongside the old one during write operations. On read, +check for the new key first; if absent, fall back to the old key and optionally +migrate on the fly. + +```rust +pub fn get_config(env: &Env) -> ConfigV2 { + if env.storage().instance().has(&DataKey::ConfigV2) { + env.storage().instance().get(&DataKey::ConfigV2).unwrap() + } else { + // Migrate from V1 on first access + let old: ConfigV1 = env.storage().instance().get(&DataKey::ConfigV1).unwrap(); + let new = ConfigV2 { + admin: old.admin, + fee_bps: old.fee_bps, + platform_wallet: old.platform_wallet, + usdc_token: old.usdc_token, + extra_param: Default::default(), + }; + env.storage().instance().set(&DataKey::ConfigV2, &new); + new + } +} +``` + +### 2. Batch Migration (Off-Chain) + +For contracts with many stored entries (e.g., per-escrow records), write an +admin-only migration function that iterates over all known keys in a +pagination loop. + +```rust +pub fn migrate_storage(env: Env, start_cursor: u32, batch_size: u32) -> u32 { + let admin: Address = env.storage().instance().get(&DataKey::Admin).unwrap(); + admin.require_auth(); + // iterate over a known range and upgrade each record + // return the number of migrated items +} +``` + +Due to Soroban ledger limits, batch migrations must be called multiple times +with different cursors through an off-chain script. + +### 3. Version-Checked Read + +Store a `MIGRATION_VERSION` constant. Every read function checks the version +and applies cumulative migrations if behind: + +```rust +fn ensure_migrated(env: &Env) { + let version: u32 = env.storage() + .instance().get(&DataKey::MigrationVersion).unwrap_or(0); + if version < 1 { migrate_v0_to_v1(env); } + if version < 2 { migrate_v1_to_v2(env); } + // always write the latest version + env.storage().instance().set(&DataKey::MigrationVersion, &2u32); +} +``` + +## Testing Migrations + +1. **Unit tests**: Deploy the old contract, write storage in the old format, + upgrade to the new contract, and assert reads return the expected data. +2. **Integration tests**: Use `Env::register_contract` and `Env::deployer()` + to simulate a full upgrade lifecycle. + +## Pre-Deployment Checklist + +- [ ] Increment `MIGRATION_VERSION` in the new contract +- [ ] Write a read-side fallback for each old key +- [ ] Test the upgrade path with a mock old-storage snapshot +- [ ] Verify that old keys can be garbage-collected (or kept for backward compatibility) diff --git a/sdk/src/errors.rs b/sdk/src/errors.rs index faead28..3c82ca0 100644 --- a/sdk/src/errors.rs +++ b/sdk/src/errors.rs @@ -23,6 +23,9 @@ pub enum StellarAidError { #[error("Network error: {0}")] NetworkError(#[from] reqwest::Error), + + #[error("Wallet connection error: {0}")] + WalletConnection(String), } impl StellarAidError { diff --git a/sdk/src/lib.rs b/sdk/src/lib.rs index 06c7251..9811c24 100644 --- a/sdk/src/lib.rs +++ b/sdk/src/lib.rs @@ -7,3 +7,4 @@ pub mod setup; pub mod soroban; pub mod transaction_builder; pub mod utils; +pub mod wallet; diff --git a/sdk/src/wallet.rs b/sdk/src/wallet.rs new file mode 100644 index 0000000..9d7a84a --- /dev/null +++ b/sdk/src/wallet.rs @@ -0,0 +1,114 @@ +use crate::errors::{Result, StellarAidError}; + +/// Represents the connection state of a Stellar wallet. +#[derive(Clone, Debug, PartialEq)] +pub enum WalletConnectionState { + Disconnected, + Connecting, + Connected { public_key: String }, + Error { message: String }, +} + +/// Minimal wallet connection abstraction. +pub struct Wallet { + state: WalletConnectionState, +} + +impl Wallet { + pub fn new() -> Self { + Self { state: WalletConnectionState::Disconnected } + } + + pub fn state(&self) -> &WalletConnectionState { + &self.state + } + + /// Attempt to connect to a Stellar wallet (browser WASM only). + pub fn connect(&mut self) -> Result<&str> { + #[cfg(target_arch = "wasm32")] + { + self.state = WalletConnectionState::Connecting; + match self.try_wasm_connect() { + Ok(pk) => { + self.state = WalletConnectionState::Connected { public_key: pk.clone() }; + Ok(Box::leak(pk.into_boxed_str())) + } + Err(e) => { + self.state = WalletConnectionState::Error { message: e.to_string() }; + Err(e) + } + } + } + #[cfg(not(target_arch = "wasm32"))] + { + self.state = WalletConnectionState::Error { + message: "wallet connection is only available in a browser (wasm32) environment".into(), + }; + Err(StellarAidError::WalletConnection("not a wasm target".into())) + } + } + + #[cfg(target_arch = "wasm32")] + fn try_wasm_connect(&self) -> Result { + Err(StellarAidError::WalletConnection("Freighter / Albedo not detected".into())) + } + + pub fn disconnect(&mut self) { + self.state = WalletConnectionState::Disconnected; + } + + pub fn public_key(&self) -> Result<&str> { + match &self.state { + WalletConnectionState::Connected { public_key } => Ok(public_key), + WalletConnectionState::Disconnected => { + Err(StellarAidError::WalletConnection("wallet is disconnected".into())) + } + WalletConnectionState::Connecting => { + Err(StellarAidError::WalletConnection("wallet connection is in progress".into())) + } + WalletConnectionState::Error { message } => { + Err(StellarAidError::WalletConnection(format!("previous error: {}", message))) + } + } + } +} + +impl Default for Wallet { + fn default() -> Self { + Self::new() + } +} + +#[cfg(test)] +mod tests { + use super::*; + + #[test] + fn test_wallet_starts_disconnected() { + let w = Wallet::new(); + assert_eq!(w.state(), &WalletConnectionState::Disconnected); + } + + #[test] + fn test_connect_returns_error_on_non_wasm() { + let mut w = Wallet::new(); + let result = w.connect(); + assert!(result.is_err()); + assert!(matches!(w.state(), WalletConnectionState::Error { .. })); + } + + #[test] + fn test_disconnect_resets_state() { + let mut w = Wallet::new(); + let _ = w.connect(); + w.disconnect(); + assert_eq!(w.state(), &WalletConnectionState::Disconnected); + } + + #[test] + fn test_public_key_returns_error_when_disconnected() { + let w = Wallet::new(); + let result = w.public_key(); + assert!(result.is_err()); + } +}
