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
The two main changes in this pull request:
Launching query execution as an asynchronous task that performs a callback upon completion or failure of a query. (Which also sets us up for callbacks progressive results)
Moving away from using the Result of a query execution to return an error. Instead we'll use an error event to return an error
Additionally, some nice refactoring and cleaning up of the unit tests to take advantage of the cool RequestContext mock tooling by @kevcunnane
* Initial commit of refactor to run execution truely asynchronously
* Moving the storage of the task into Query class
Callbacks for completion of a query and failure of a query are setup as
events in the Query class. This actually sets us up for a very nice
framework for adding batch and resultset completion callbacks.
However, this also exposes a problem with cancelling queries and returning
errors -- we don't properly handle errors during execution of a query
(aside from DB errors).
* Wrapping things up in order to submit for code review
* Adding fixes as per comments
* Implemented connection cancellation
* Made connect requests return immediately and created a separate connection complete notification
* Fix spelling
* Fix sorting
* Add separate lock for cancellation source map
Fixing a bug where in various situations, the files used for temporary storage of query results would be leftover. In particular, the following changes were made:
* When the dispose query request is submitted, the corresponding query is now disposed in addition from being removed from the list of active queries
* When a query is cancelled, it is disposed after it is cancelled
* If a query already exists for a given ownerURI, the existing query is disposed before creating a new query
* All queries are disposed when the query execution service is disposed (ie, at shutdown of the service)
A unit test to verify the action of the dispose method for a ResultSet was added.
* Ensuring queries are disposed
Adding logic to dispose any queries when:
* URI that already has a query executes another query
* A request to dispose a query is submitted
* A request to cancel a query is submitted
* Small tweaks for cleanup of query execution service
* inital pipe of line numbers and getting text from workspace services
* tests compile
* Fixed bug regarding tests using connections on mac
* updated tests
* fixed workspace service and fixed tests
* integrated feedback
* CredentialService initial impl with Win32 support
- Basic CredentialService APIs for Save, Read, Delete
- E2E unit tests for Credential Service
- Win32 implementation with unit tests
* Save Password support on Mac v1
- Basic keychain support on Mac using Interop with the KeyChain APIs
- All but 1 unit test passing. This will pass once API is changed, but checking this in with the existing API so that if we decide to alter behavior, we have a reference point.
* Remove Username from Credentials API
- Removed Username option from Credentials as this caused conflicting behavior on Mac vs Windows
* Cleanup Using Statements and add Copyright
* Linux CredentialStore Prototype
* Linux credential store support
- Full support for Linux credential store with tests
* Plumbed CredentialService into Program init
* Addressing Pull Request comments
