- Connection info cache is now per-DB instead of per-server. This has the downside of increasing #queries, but is required in order to correctly handle isSqlDW since this changes for each database on an Azure server.
* added a new tool to store SQL connections locally. Modified the peek definition tests to create test database before running test
* fixed failing test QueryExecutionPlanInvalidParamsTest
* Fixes based on code review comments
* fixed failing test GetSignatureHelpReturnsNotNullIfParseInfoInitialized
* Add CancelTokenKey for uniquely identifying cancelations of Connections associated with an OwnerUri and ConnectionType string.
* Update ConnectionInfo to use ConcurrentDictionary of DbConnection instances. Add wrapper functions for the ConcurrentDictionary.
* Refactor Connect and Disconnect in ConnectionService.
* Update ConnectionService: Handle multiple connections per ConnectionInfo. Handle cancelation tokens uniquely identified with CancelTokenKey. Add GetOrOpenConnection() for other services to request an existing or create a new DbConnection.
* Add ConnectionType.cs for ConnectionType strings.
* Add ConnectionType string to ConnectParams, ConnectionCompleteNotification, DisconnectParams.
* Update Query ExecuteInternal to use the dedicated query connection and GetOrOpenConnection().
* Update test library to account for multiple connections in ConnectionInfo.
* Write tests ensuring multiple connections don’t create redundant data.
* Write tests ensuring database changes affect all connections of a given ConnectionInfo.
* Write tests for TRANSACTION statements and temp tables.
This change is a reworking of the way that messages are sent to clients from the service layer. It is also a reworking of the protocol to ensure that all formulations of query send back events to the client in a deterministic ordering. To support the first change:
* Added a new event that will be sent when a message is generated
* Messages now indicate which Batch (if any) generated them
* Messages now indicate if they were error level
* Removed message storage in Batch objects and BatchSummary objects
* Batch objects no longer have error state
Add IntegrationTests project. Move all tests ifdef'd with LIVE_CONNECTION_TESTS to IntegrationTests project. Delete files that have no remaining code. Update codecoverage.bat to run integration tests
