* Working on a better database abstraction
After [this question in the chat](https://matrix.to/#/!oJFtttFHGfnTGrIjvD:matrix.cashu.space/$oJFtttFHGfnTGrIjvD:matrix.cashu.space/$I5ZtjJtBM0ctltThDYpoCwClZFlM6PHzf8q2Rjqmso8)
regarding a database transaction within the same function, I realized a few
design flaws in our SQL database abstraction, particularly regarding
transactions.
1. Our upper abstraction got it right, where a transaction is bound with `&mut
self`, so Rust knows how to handle its lifetime with' async/await'.
2. The raw database does not; instead, it returns &self, and beginning a
transaction takes &self as well, which is problematic for Rust, but that's not
all. It is fundamentally wrong. A transaction should take &mut self when
beginning a transaction, as that connection is bound to a transaction and
should not be returned to the pool. Currently, that responsibility lies with
the implementor. If a mistake is made, a transaction could be executed in two
or more connections.
3. The way a database is bound to our store layer is through a single struct,
which may or may not internally utilize our connection pool. This is also
another design flow, in this PR, a connection pool is owned, and to use a
connection, it should be requested, and that connection is reference with
mutable when beginning a transaction
* Improve the abstraction with fewer generics
As suggested by @thesimplekid
* Add BEGIN IMMEDIATE for SQLite
* feat: add keyset u32 mapping migration and duplicate handling
- Add new database migration (version 3) to include u32 representation for keysets
- Implement migration for both redb and SQL databases
- Add duplicate detection and handling for keyset entries
- Create unique index constraint for keyset_u32 column in SQL
- Update keyset storage to include u32 identifiers
- Handle backwards compatibility for existing databases
* chore: clippy
* refactor(cashu): simplify keyset ID verification logic
- Consolidate match expression into a single expression
- Use direct comparison with ensure_cdk macro
- Improve readability of keyset ID validation
* refactor(cdk): rename `fetch_keyset_keys` to `load_keyset_keys` for clarity
- Renamed `fetch_keyset_keys` to `load_keyset_keys` across multiple modules to better reflect its behavior of loading keys from local storage or fetching from mint when missing.
- Added debug logging to indicate when keys are being fetched from the mint.
- Simplified key loading logic in `update_mint_keysets` by removing redundant existence checks.
* chore: remove unused vec
* feat(cdk-integration-tests): refactor regtest setup and mintd integration
- Replace shell-based regtest setup with Rust binary (start_regtest_mints)
- Add cdk-mintd crate to workspace and integration tests
- Improve environment variable handling for test configurations
- Update integration tests to use proper temp directory management
- Remove deprecated start_regtest.rs binary
- Enhance CLN client connection with retry logic
- Simplify regtest shell script (itests.sh) to use new binary
- Fix tracing filters and improve error handling in setup
- Update dependencies and configurations for integration tests
fix: killing
chore: comment tests for ci debugging
chore: compile
Revert "chore: comment tests for ci debugging"
This reverts commit bfc594c11cf37caeaa6445cb854ae5567d2da6bd.
* chore: sql cipher
* fix: removal of sqlite cipher
* fix: auth password
* refactor(cdk-mintd): improve database password handling and function signatures
- Pass database password as parameter instead of parsing CLI args in setup_database
- Update function signatures for run_mintd and run_mintd_with_shutdown to accept db_password
- Remove direct CLI parsing from database setup logic
- Fix auth database initialization to use correct type when sqlcipher feature enabled
- Add new Goose recipes for generating conventional commit messages and updating changelogs
- Include recipes for both staged changes and recent commits analysis
- Add convenient Just commands for running the new recipes
- Update README with usage instructions for the new recipes ([thesimplekid]).
The primary purpose of this new crate is to have a common and shared codebase
for all SQL storage systems. It would force us to write standard SQL using best
practices for all databases.
This crate has been extracted from #878
Remove crane and fenix dependencies along with their associated build
infrastructure. This simplifies the flake to focus on development
environments while removing package builds and applications.
Move Nix flake input checking from the main CI pipeline to a dedicated
daily scheduled workflow to reduce CI build time while maintaining
regular dependency monitoring.
Custom currency units were incorrectly being converted to uppercase
during deserialization. This change ensures custom units maintain
their original case while still allowing case-insensitive matching
for standard units.
