* feat: Implement `get_transaction_depth` for drivers * test: Verify `get_transaction_depth()` on postgres * Refactor: `TransactionManager` delegation without BC SQLite implementation is currently WIP * Fix: Avoid breaking changes on `AnyConnectionBackend` * Refactor: Remove verbose `SqliteConnection` typing * Feat: Implementation for SQLite I have included `AtomicUsize` in `WorkerSharedState`. Ideally, it is not desirable to execute `load` and `fetch_add` in two separate steps, but we decided to allow it here since there is only one thread writing. To prevent writing from other threads, the field itself was made private, and a getter method was provided with `pub(crate)`. * Refactor: Same approach for `cached_statements_size` ref: a66787d36d62876b55475ef2326d17bade817aed * Fix: Add missing `is_in_transaction` for backend * Doc: Remove verbose "synchronously" word * Fix: Remove useless `mut` qualifier * feat: add Connection::begin_with This patch completes the plumbing of an optional statement from these methods to `TransactionManager::begin` without any validation of the provided statement. There is a new `Error::InvalidSavePoint` which is triggered by any attempt to call `Connection::begin_with` when we are already inside of a transaction. * feat: add Pool::begin_with and Pool::try_begin_with * feat: add Error::BeginFailed and validate that custom "begin" statements are successful * chore: add tests of Error::BeginFailed * chore: add tests of Error::InvalidSavePointStatement * chore: test begin_with works for all SQLite "BEGIN" statements * chore: improve comment on Connection::begin_with * feat: add default impl of `Connection::begin_with` This makes the new method a non-breaking change. * refactor: combine if statement + unwrap_or_else into one match * feat: use in-memory SQLite DB to avoid conflicts across tests run in parallel * feedback: remove public wrapper for sqlite3_txn_state Move the wrapper directly into the test that uses it instead. * fix: cache Status on MySqlConnection * fix: compilation errors * fix: format * fix: postgres test * refactor: delete `Connection::get_transaction_depth` * fix: tests --------- Co-authored-by: mpyw <ryosuke_i_628@yahoo.co.jp> Co-authored-by: Duncan Fairbanks <duncanfairbanks6@gmail.com>
