postgresql2: ^1.6.2 copied to clipboard

A fork of Greg's PostgreSQL driver (xxgreg/postgresql) using conserved substitution respecting strings and @@ operators. Also optimizing the pool implementation aggressivly.

Version 1.6.2 #

  • The stats parameter added to onQuery and onExecute to pass application-specific data for monitoring the connections, such as detecting abnormal access, such as a dead loop.
  • The onOpen callback added to PoolSettings to prepare the stats paremeter mentioned above.

Version 1.0.4 #

  • Pool.typeConverter added.

Version 1.0.3 #

  • runInTransaction supports nested transactions.

Version 1.0.2 #

  • The onExecute and onQuery callback are added to PoolSettings to detect unexpected patterns, such as a missing @ or low-performance statements.

Version 1.0.1 #

  • Fix #20: remove connections from the pool when detecting server restarted/crashed
  • Fix #21: retry if failed to establish a connection

Version 1.0.0 #

  • Migrate to null safety
  • Numeric and Decimal types are consider as double, instead of BigInt.
    • It means the precision is bounded by double.
  • The getConnectionName() and getDebugName() arguments are simplifed as String? connectionName and String? debugName.
  • Settings.fromMap and Settings.toMap are removed.
  • The mockSocketConnect argument is removed.

Version 0.7.7 #

  • Rename freeConnections to limitConnections
  • Add limitTimeout to control how long to wait when exceeding limitConnections

Version 0.7.6 #

  • If freeConnections is set, we'll wait up to 700ms, if number of connections exceeds [freeConnections]. It helps to reduce number of connections if there are a lot of short-lived connections.

Version 0.7.4 #

  • Settings.onMaxConnection introduced to monitor the usage of DB connections.

Version 0.7.3 #

  • freeConnections introduced to control maximal number of connections kept in a pool.

Version 0.7.0 #

  • Breaking: the substition with a Map instance won't treat number identifiers specially. For example, if @0 is specified, it will consider the identifier as '0' and retrieve values['0'].

Version 0.6.0 #

  • Array type with single dimension supported.
  • isUtcTimeZone removed from DefaultTypeConverter.decodeDateTime() and related functions.
  • DefaultTypeConverter.decodeDateTime() converts the DateTime instance to local time by calling DateTime.toLocal().

Version 0.5.8 #

  • encodeString() ignores the trimNull argument. Now it always removes the null characters.

Version 0.5.7 #

  • Pool.busyConnectionCount counts only inUse.

Version 0.5.6 #

  • Connect.runInTransaction returns the result of the transaction operation.

Version 0.5.5 #

  • Pool.debugName removed.
  • Make the pool more likely to shrink.

Version 0.5.4 #

  • PoolImpl with two new methods: pooledConnectionCount and busyConnectionCount

Version 0.5.3 #

  • Support BigInt.
    • Note: _PG_NUMERIC will be converted to BigInt, if possible (instead of String). Otherwise, it is converted to a String instance.

Version 0.5.2 #

  • Upgrade to Dart 2.5

Version 0.3.4 #

  • Update broken crypto dependency.

Version 0.3.3

  • Fix #73 Properly encode/decode connection uris. Thanks to Martin Manev.
  • Permit connection without a password. Thanks to Jirka Daněk.

Version 0.3.2

  • Improve handing of datetimes. Thanks to Joe Conway.
  • Remove manually cps transformed async code.
  • Fix #58: Establish connections concurrently. Thanks to Tom Yeh.
  • Fix #67: URI encode db name so spaces can be used in db name. Thanks to Chad Schwendiman.
  • Fix #69: Empty connection pool not establishing connections.

Version 0.3.1+1

  • Expose column information via row.getColumns(). Credit to Jesper Håkansson for this change.

Version 0.3.0

  • A new connection pool with more configuration options.

  • Support for json and timestamptz types.

  • Utc time zone support.

  • User customisable type conversions.

  • Improved error handling.

  • Connection.onClosed has been removed.

  • Some api has been renamed, the original names are still functional but marked as deprecated.

    • import 'package:postgresql/postgresql_pool.dart' => import 'package:postgresql/pool.dart'
    • Pool.destroy() => Pool.stop()
    • The constants were upper case and int type. Now typed and lower camel case to match the style guide.
    • Connection.unhandled => Connection.messages
    • Connection.transactionStatus => Connection.transactionState

    Thanks to Tom Yeh and Petar Sabev for their helpful feedback.
