SQLAlchemy 1.3 has been end-of-life since 2021, and alembic was held at 1.10
because newer releases need SQLAlchemy 2. This is a mechanical port; the code
stays synchronous.
- SQLAlchemy[asyncio]==2.0.54, alembic==1.20.0.
- Model annotations use Mapped[...] (2.0 rejects bare annotations on mapped
attributes); declarative_base moves to sqlalchemy.orm.
- Plain SQL strings go through text() or exec_driver_sql; schema_ddl.execute_sql
accepts a SQLAlchemy Connection or a raw sqlite3 connection, so rebuild_fts
works from the baseline migration again.
- Session.get replaces Query.get; session.in_transaction() replaces
session.transaction; cache_ok on MediaPathType and FancyJSON.
- The tag-directory sync query joins through TagFile's relationships instead of
the legacy two-entity outerjoin.
- Section-hint rows use attribute access (2.0 rows are tuples).
- Migrations run on an AUTOCOMMIT connection, matching 1.3, where each
statement committed on its own. 2.0 autobegins, so the unique-stem
migration's read snapshot could not become a writer after its helpers wrote
on another connection ("database is locked"). The begin listener emits no
BEGIN for AUTOCOMMIT connections.
- Newer alembic compares column types: WrolpiKV now describes the TEXT table
its migration created.
- The test database installs its DDL inside engine.begin(); 2.0 connections
no longer autocommit, so the FTS tables were rolled back.
- Dependabot now holds SQLAlchemy at 2.0 instead of 1.3.
