v0.5.1

Bug fixes

• remove_events_from_catalogue checked membership by Python id(), which broke whenever the caller resolved the event via get_events(uuid=...) (the 0.5.0 fast path returns wrappers backed by _LazyBackendEntity, a different Python object from the one stored in catalogue.events). Membership is now compared on the SQL primary key, matching add_events_to_catalogue.
• After event.remove(permanently=True), catalogue.events kept the deleted ORM Event in its in-memory collection. A later add_events_to_catalogue() with a freshly created event reusing the same UUID was wrongly rejected as "already in catalogue". Backend.remove now detaches the event from every catalogue's events collection before session.delete.
• The fast-path query was leaking _LazyBackendEntity proxies into SQLAlchemy relationships. Wrapper→backend boundaries (add/remove_events_to_catalogue, _BackendBasedEntity.remove) now resolve proxies to identity-mapped ORM entities before handing them to SQLAlchemy.

Two regression tests cover both scenarios.

v0.5.0

Highlights

This release modernizes the internals and migrates the on-disk schema. Existing databases are auto-migrated on first open and a timestamped .sqlite.backup is created next to them.

Storage / migrations

• Predicates serialized as JSON instead of pickle (Alembic migration 4a1d43bb9936)
• Tags & products stored as JSON arrays instead of comma-separated strings (Alembic migration df61d8f30e7c); the comma-restriction on tag/product values is removed
• sqlalchemy_utils dependency dropped
• event.rating field added (Alembic migration 9a655086fb51)

API / DSL

• New filtering DSL: from tscat.filtering import event then event.author == "Alice", combinable with & | ~
• get_catalogue(uuid=...) / get_catalogue(name=...) / get_catalogue(predicate=...) helper
• existing_tags() returns the union of all tags used across events and catalogues
• Predicate.to_dict() / Predicate.from_dict() for explicit JSON serialization

Internals

• Migrated to SQLAlchemy 2.0 (DeclarativeBase, Mapped[T], mapped_column, select())
• Build system migrated to uv + hatchling
• Python ≥ 3.10 (3.10 — 3.14 tested in CI)

Performance

• ~14 % faster event creation, 1.6× faster catalogue reads, 2.1× faster tag filtering on a 10K-event benchmark
• Raw-SQL fast path for bulk event loads (~2× speedup)

Fixes

• Eager session.add in Session._track — fixes silent relationship-skip warning on import (#)
• Mutable default arguments removed
• Identity-map cleared after rollback()
• Import dedup for catalogues batched by UUID set
• Set-based remove_events_from_catalogue (was O(n·m))
• is_removed() returns False after restore() again
• Bulk import on large catalogues no longer hits the SQLite bind-variable limit
