If any target data exists (e.g. `proof`, `blind_signature`, `keyset`), abort the migration to prevent corruption. + - Verify that the source database contains the standard Nutshell schema. +5. **Data Extraction & Migration**: Transfer the records from the source database to the target database in topological order inside a single database transaction. +6. **Auxiliary Index / Total Recovery**: Populate the CDK aggregate tables (like `keyset_amounts`) and history ledgers. +7. **Verify**: Run a sanity check comparing row counts and log completion. + +--- + +## 2.

Handling Critical Edge Cases + +1. **Chunked Pagination / Bounded Memory Streaming**: To prevent out-of-memory errors on massive nutshell databases (like Minibits), we retrieve all large datasets (`mint_quotes`, `melt_quotes`, `promises`, `proofs_used`, `proofs_pending`) in constant-sized batches of 2000 rows. This guarantees flat, highly predictable, and negligible memory overhead throughout the entire process. +2. **Pre-flight Corruption Check**: We query `SELECT COUNT(*) FROM proof` and `keyset` on the target DB. If any target data exists (e.g. `proof`, `blind_signature`, `keyset`), abort the migration to prevent corruption. +3. **Byte Conversions**: Binary columns are decoded from Hex strings to raw byte vectors (`Vec`) to ensure database queries in CDK continue to hit indexes correctly. +4. **Aggregate Keyset Metrics Recovery**: To repopulate `keyset_amounts` in CDK, we run three aggregate insert/update statements at the end of the migration: + - Compute total issued per keyset from `blind_signature` + - Compute total redeemed per keyset from spent `proof`s +5. **Resilient Date / Timestamp Parsing**: + - Check if a timestamp value is integer-string; if so, parse as unix timestamp. + - If stored as string (e.g. `"2026-05-12 14:00:23.123"`), parse with format specifiers (e.g., `"%Y-%m-%d %H:%M:%S"` or `"%Y-%m-%d %H:%M:%S.%f"`) to convert to standard epoch seconds. + +--- + +## 4. Implementation Steps + +1. **Direct DB Connectors**: Direct, performant connections to target and source databases are handled with `rusqlite` and `tokio-postgres`. +2. **Cargo configuration**: Include database driver dependencies under target compile features (`sqlite`/`postgres`) in `cdk-mintd/Cargo.toml`. +3. **Register Subcommand**: Add `Subcommand::MigrateNutshell` to `cli.rs` and configure `main.rs` to route to `migrate::run_migration(...)` if specified. +4. **Implement Migration Logic**: Create `cdk-mintd/src/migrate.rs` containing chunk-paged query mappings, row-decoders, and transactional bulk insertion logic. diff --git a/crates/cdk-integration-tests/Cargo.toml b/crates/cdk-integration-tests/Cargo.toml index 989c057cdc..62c90d33cf 100644 --- a/crates/cdk-integration-tests/Cargo.toml +++ b/crates/cdk-integration-tests/Cargo.toml @@ -26,6 +26,7 @@ cdk-lnd = { workspace = true } cdk-ldk-node = { workspace = true } cdk-axum = { workspace = true } cdk-sqlite = { workspace = true } +rusqlite = { version = "0.31", features = ["bundled"] } cdk-redb = { workspace = true } cdk-fake-wallet = { workspace = true } cdk-common = { workspace = true, features = ["mint", "wallet", "http"] } diff --git a/crates/cdk-integration-tests/tests/nutshell_migration_fuzzer.rs b/crates/cdk-integration-tests/tests/nutshell_migration_fuzzer.rs new file mode 100644 index 0000000000..2275b70579 --- /dev/null +++ b/crates/cdk-integration-tests/tests/nutshell_migration_fuzzer.rs @@ -0,0 +1,718 @@ +use std::collections::{HashMap, HashSet};
