dox_postgres_native 3.0.0-alpha.4

Fast native Postgres client for Dart, the default Postgres driver of the Dox ORM. Rust (tokio-postgres) owns the connections, your code stays in Dart.

3.0.0-alpha.4

• Less work per request. Rust copies a batch of requests once and keeps slices of it, instead of one copy of the SQL and of each parameter. A batch of plain queries uses one timeout timer, not one per query. Dart keeps waiting requests in a list, not a map.

3.0.0-alpha.3

• Column names and types are decoded once per result shape. The next result with the same columns reuses them.
• Breaking: this package no longer depends on dox_orm. PostgresNativeDriver moved into dox_orm, which now uses it as its default Postgres driver. This package keeps PgNativePool.
• Fix: a request never got an answer in two cases. A value that Dart can not decode (eg. a timestamp out of the DateTime range) lost every other result of the same batch. A request sent to a transaction after its end (eg. a second rollback) was dropped. Both now fail with a clear error.
• A request that gets no answer in 5 minutes fails with a timeout error (like queryTimeout of the postgres package). Connect timeout is 15 s. A transaction that Dart does not end in 5 minutes is rolled back, so its connection goes back to the pool.
• tool/stress.dart: a stress test that finds requests that never finish.
• Faster queries. Plain queries now share connections: tokio-postgres sends the queries of one connection together (pipelining). One tokio task runs each batch from Dart, not one task per query. The SQL bytes are cached, and binding named parameters builds no extra Set.

3.0.0-alpha.2

• First release.
• Native Postgres driver: Rust (tokio-postgres, deadpool-postgres) owns the connections. Your code stays in Dart.
• PostgresNativeDriver for the Dox ORM. Same types and exceptions as the postgres package.
• PgNativePool: queries, transactions, one pool for many isolates.
