mongo_dart

• Fixed a problem in Timestamp class so that seconds and increment were inverted in reading from db.
• Decoupled the Timestamp class from the newly created BsonTimestamp one.

• Added SCRAM-SHA-256 authentication mechanism If no authentication mechanism is set, as a first try the driver analyze the server response that returns the available scram mechanisms for the required user, otherwise, SCRAM-SHA-256 is set starting from release 4.0.

  BREAKING CHANGE Incidentally a potential breaking change has been introduced. If there is any problem during authentication, in previous versions a map containing the error message was thrown. Now a MongoDartError object is thrown.

  Please NOTE By default the driver automatically sets SCRAM-SHA-256 if the server release is equal or greater to 4.0. Unfortunately Atlas does not yet support SHA-256, and does not return informations about the supported authentication mechanisms for the user, so the driver, when detects the connection error, automatically downgrades to SHA-1 If you want to avoid the first attempt, you can set the autentication mechanism to SHA-1 in the connection string.

• Removed deprecated MD5 calculation in GridFs

• changed documentation references, now pointing directly on GitHub

• Fix in README. There was a wrong example on how to call the replaceOne method.

• Fixed problem with tls CAFile parameter if passed more than once.

• Documentation and examples

• distinct()
• reorganized folder with new commands
• more examples and docs

• Renamed DeleteRequest classes as DeleteStatement
• updateOne(), replaceOne() and updateMany()
• modermFindAndModify()
• bulkWrite()
• watch()
• all crud methods have been modified to call the modern version if MongoDb has a version of 3.6 or greater.

• DbCollection.deleteOne()
• DbCollection.deleteMany()

Breaking Changes

• The hidden class _Connection has been renamed Connection. If you have already your own Connection class may be that they conflict. In this case, you shoul hide the Connection class while importing MongoDart in your sources. Ex.dart import 'package:mongo_dart/mongo_dart.dart' hide Connection;

Other Changes

• OP_MSG operations and commands. See the README file.
• Decimal128 Type (inherited from BSON enhancements)

• Added tls client and server certificate management
• Created method .onlyFirst() in class ModernCursor

• Test for text index.
• Fix problem wit "OPENING" state in db. When a socket error happened during opening, the state was't resetted so that any new db.open() attempt failed.
• Closing a db when the connection socket was null threw error.
• Changed the way the socket error is thrown on db.open(): All errors detected are collected.
  1. If after all the attempts the master connection is not on, an error is thrown relative to the the first server tested. This for compatibility reason with the previous way the message was thrown.
  2. If the master connection is on, the errors are logged as warning.
• The socket error message has been changed to comprehend also the address of the server, so it is easier to identify the problem.
• If an authentication error occurs, the relative socket is closed.

• New isConnected Db getter. It returns true if the state of the database is open and at least the primary connection is on.
• db._masterConnectionVerified() now throws an explicit error if the db state is not OPEN (it was throwing a NoSuchMethodError).

• New Db constructor (Db.create()) that accepts also the url in DNS Seedlist Connection Format (mongodb+srv://)

Secure connection implementation

• Lint clean-up

• Upgraded to mongo_dart_query 0.4.1. The update adds aggregation pipeline builder.

• Updates for Dart 2.5 compatibility. As of Dart 2.5, the Socket class emits Uint8List, rather than plain List<int>, so some fixes were necessary to allow the package to continue to function.
  • Courtesy of @a14n, thank you!
  • Resolves https://github.com/mongo-dart/mongo_dart/issues/160, among other issues.

• Upgraded uuid constraint to ^2.0.0.

• Added cursor option to DbCollection.aggregate.
  • Courtesy of @jodinathan, thank you!
  • Resolves https://github.com/mongo-dart/mongo_dart/issues/120
  • See PR: https://github.com/mongo-dart/mongo_dart/pull/139
• Added "Tobe O" to authors in pubspec.yaml.

• Cast fixes, for compatibility with Dart 2.
• Moved from dart:convert usage to package:dart2_constant, for the sake of backwards compatibility.

• Changed the signature of DbCollection.remove; its selector parameter is now required, while writeConcern is now a named optional parameter.

Future remove(selector, {WriteConcern writeConcern});

Resolves #73.

• Strong mode compliance. Preparing for Dart 2.0

• Fix bad type in _Connection class

• Minor changes, commented out code removed
• Big chunk of tests was commented out in 0.2.6 by error. All tests restored.

• update for new sdk (with 1.17.0 [MongoMessageHandler] was broken in checked mode)
• upgrade to current version of crypto package, and it's new (Converter based) API

• Fixed markdown for pub.

• Moved mongo_dart project to a new organization on GitHub.
• Authentication schemes now use Secure Random coming from dart:math since 1.14. Note that this version now required SDK version >= 1.14 because of this
• Added sort by text score to the query builders.
