Turso is a distributed SQLite database built on libSQL, offering HTTP-based
connectivity with auth token authentication. This change adds full support:
- New DatabaseType::Turso and PoolKind::Turso variants
- TursoClient driver using libSQL HTTP pipeline API (/v2/pipeline)
- Bearer token auth via password or url_params (auth_token=)
- Multi-statement batch pipeline for transactional integrity
- Standalone BEGIN/COMMIT/ROLLBACK treated as no-ops (pipeline is auto-commit)
- Full metadata support: tables, columns, indexes, foreign keys, triggers, DDL
- Frontend: connection form, SQL completion (SQLite syntax), capability sets
- Built-in databases (SQLite/Turso/DuckDB/RQLite/Access) placed first in selector
- Unit tests (15) + integration tests against live libsql-server (12)
- Single connection pool, skips TCP probe
Closes#948
- Add accessCapabilities based on UCanAccess DDL support testing
- CREATE TABLE, ADD COLUMN, CREATE INDEX are supported
- DROP COLUMN, ALTER COLUMN, RENAME COLUMN, DROP INDEX are not supported
- Use H2 SQL dialect for generated DDL
Add IRIS as a new agent-driven database type with:
- iris:// connection URL scheme (default port 1972, user _SYSTEM)
- JDBC driver via agent (com.intersystems.jdbc.IRISDriver)
- Oracle-compatible DDL dialect and schema-aware SQL dialect
- Capability sets: schema-aware, tree schema, diagram, search, table structure
Closes#368
DuckDB was not recognized as a schema-aware database, so only the
default "main" schema was shown in the object tree and schema selector.
Added DuckDB to schema-aware type lists, implemented schema listing via
information_schema.schemata, and replaced hardcoded table_schema = 'main'
with parameterized queries.
