* Replacing the awful and inflexible Dictionary<string, string>[][] with a much better test data set class
* Applying all changes
* Removing unused RequestParamTests
Adding new methods for executing queries from other services (such as the upcoming edit data service). The code is written to avoid duplicating logic by using lambdas to perform custom logic.
Additionally, the service host protocol has been slightly modified to split the IMessageSender into IEventSender and IRequestSender. This allows us to use either a ServiceHost or any RequestContext<T> to send events. It becomes very convenient to use another service's request context to send the events for query execution.
**Breaking Change**: This removes the messages property for query dispose results and instead elects to use error for any errors encountered during query disposal. A result is only used when something is successful.
* Splitting IMessageSender into IEventSender and IRequestSender
* Adding inter-service method for executing queries
* Adding inter-service method for disposing of a query
* Adding null checking for the success/error handlers
This is a small API addition that allows us to execute queries directly as strings. This will make it easier to execute queries outside the confines of a workspace like VS Code.
* Refactor execution requests and events are now named less redundantly and moved into a separate namespace for organization. This is the bulk of the changes.
* QueryExecuteBatchNotification -> ExecuteRequests/BatchEvents
* QueryExecuteMessageNotification -> ExecuteRequests/MessageEvent
* QueryExecuteCompleteNotification -> ExecuteRequests/QueryCompleteEvent
* QueryExecuteResultSetCompleteNotification -> ExecuteRequests/ResultSetEvents
* QueryExecuteSubsetRequest -> SubsetRequest.cs
* Creating an inheritance pattern where
* `ExecuteRequestParamsBase` has execution options and ID for a query execute request
* `ExecuteDocumentSelectionParams` inherits from `ExecuteRequestParamsBase` and provides a document selection
* `ExecuteStringParams` inherits from `ExecuteRequestParamsBase` and provides the query text
* Adding a helper method to get SQL text based on request type
* Through the AWESOME POWER OF POLYMORPHISM, we are able to create a request for executing straight SQL basically for free.
* **Breaking change:** query/execute => query/executeDocumentSelection to make it more obvious what is expected.
* Adding unit tests for the code that gets SQL text
* Refactoring of execute contracts into their own namespace
* Refactoring application
* Adding new request for executing queries as strings
* Adding forgotten string request
* Changing the logic for checking the request param types
* Removing redundant declarations
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
This is a reworking of the unit tests to permit us to better test events from the service host. This new Event Flow Validator class allows creating a chain of events that can then be validated after execution of the request. Each event can have its own custom validation logic for verifying that the object sent via the service host is correct. It also allows us to validate that the order of events are correct.
The big drawback is that (at this time) the validator cannot support asynchronous events or non-determinant ordering of events. We don't need this for the query execution functionality despite messages being sent asynchronously because async messages aren't sent during unit tests (due to the db message event only being present on SqlDbConnection classes). If the need arises to do async or out of order event validation, then I have some ideas for how we can do that.
* Applying the event flow validator to the query execution service integration tests
* Undoing changes to events that were included in cherry-picked commit
* Cleaning up event flow validation to query execution
* Add efv to cancel tests
* Adding efv to dispose tests
* Adding efv to subset tests
* Adding efv to SaveResults tests

This change is part of the progressive results code. It will submit a notification from the service layer to indicate when execution of a batch has completed. This notification will contain the selection for batch, execution start time, and its ID. This will enable the extension to produce a header for the batch before the batch completes, in order to make it more clear to the user that execution is going on.
* Adding new event for batch start
* Unit tests
* Fixing comments as per @kevcunnane
The main change in this pull request is to add a new event that will be fired upon completion of a resultset but before the completion of a batch. This event will only fire if a resultset is available and generated.
Changes:
* ConnectionService - Slight changes to enable mocking, cleanup
* Batch - Moving summary generation into ResultSet class, adding generation of ordinals for resultset and locking of result set list (which needs further refinement, but would be outside scope of this change)
* Adding new event and associated parameters for completion of a resultset. Params return the resultset summary
* Adding logic for assigning the event a handler in the query execution service
* Adding unit tests for testing the new event /making sure the existing tests work
* Refactoring some private properties into member variables
* Refactor to remove SectionData class in favor of BufferRange
* Adding callback for batch completion that will let the extension know that a batch has completed execution
* Refactoring to make progressive results work as per async query execution
* Allowing retrieval of batch results while query is in progress
* reverting global.json, whoops
* Adding a few missing comments, and fixing a couple code style bugs
* Using SelectionData everywhere again
* One more missing comment
* Adding new notification type for result set completion
* Plumbing event for result set completion
* Unit tests for result set events
This includes a fairly substantial change to create a mock of the
ConnectionService and to create separate memorystream storage arrays. It
preserves more correct behavior with a integration test, fixes an issue
where the test db reader will return n-1 rows because the Reliable
Connection Helper steals a record.
* Adding locking to ResultSets for thread safety
* Adding/fixing unit tests
* Adding batch ID to result set summary
This is a fairly large set of changes to the unit tests that help isolate the effectiveness of the unit tests.
* Unit tests for query execution have been split into separate files for different classes.
* Unit tests have been added for the ResultSet class which previously did not have tests
* The InMemoryStreamWrapper has been improved to share memory, creating a simulated filesystem
* Creating a mock ConnectionService to decrease noisy exceptions and prevent "row stealing". Unfortunately this lowers code coverage. However, since the tests that touched the connection service were not really testing it, this helps keep us honest. But it will require adding more unit tests for connection service.
* Standardizing the await mechanism for query execution
* Cleaning up the mechanism for getting WorkspaceService mocks and mock FileStreamFactories
* Refactor the query execution tests into their own files
* Removing tests from ExecuteTests.cs that were moved to separate files
* Adding tests for ResultSet class
* Adding test for the FOR XML/JSON component of the resultset class
* Setting up shared storage between file stream readers/writers
* Standardizing on Workspace mocking, awaiting execution completion
* Adding comment for ResultSet class
