Fixes:
The streaming protocol is now tightened to ensure that only the last message for a result set contain isCompleted=true. Now isCompleted=true is never sent in isAvailable message.
Tightened logic in sending messages to make sure that no duplicate messages get sent out due to concurrent processing.
Made a fix to a null reference exception when processing special action which was a pre-existing benign bug.
Testing: Added 1 more new test that runs existing tests concurrently 1000 times to make sure no random timing issues are observed and tightened verifications to existing tests to ensure no duplicate messages and only one isComplete=true message is sent across.
* tightening the protocal to ensure only one message (the last one) with completed=true is sent back for a single result set within a query batch
This changes adds the following two notifications from the results processing within a batch. These new notifications allows a consumer to stream results from a resultset instead of getting them all at once after the entire resultset has been fetched.
ResultsAvailable
This is issued after at least 1 row has been fetched for this resultset.
ResultsUpdated
This is issued periodically as more rows are available on this resultset. The final send of this notification when all rows have been fetched has the property 'Complete' set to true in the ResultSummary object.
Detailed Change Log:
* Initial completed implementation of QueryResults stream feature. 3 unittests still need fixing
* Fix for the 3 failing test. I will look into making MockBehavior strict again for the three tests later
* Making GetReader/GetWriter use filestream objects in FileShare.ReadWrite mode so the file can be concurrently read and written
* Changing resultsAvailable also to fire off on a timer instead of after 1st row
* adding a project for clr TableValuedFunction to produce result set with delays after each row. This is helpful in end to end testing.
* Fixing up some tests and simplifying implementation of result update timer
* Address review comments
* Some test fixes
* Disabled flaky test verification
* Reopen connections prior to creating query execution data readers
* Reopen connection if an exception was rasied executing the query
* Fix unit tests
* Fix to make sql exceptions surface properly to user (with important notes!)
* Adding support for detecting column size issues when updating a cell
* Adding unit tests for the exception on read scenario
* change simple execute to open a new connection and close it every query
* updated tests for simple execute
* removed an unnecessary connect
* refactored code to be more readable
* global try catch on simple execute
* added multiple execution test
* update execution to be asynchrous; update tests to account for asynchrounous nature
* inital request
* refactored query execution failure callback to take exception
* added failure callback to execute and return
* added test for query execute and return
* updated params
* removed dead code
* addressed feedback; added multiple active result set support; updated tests
* addessed feedback and added testing and errors and verification
* change <= to ==
* changed name of trashQ to removedQuery
This change ensures that when calling `requestContext.SendError` you are only able to supply parameters that match the language service beta protocol expected Error object. In other words, you have to provide an error message and optionally and error code.
# **BREAKING API CHANGES**
This will break displaying errors in Microsoft/vscode-mssql. I will be making changes to properly handle the error object shortly.
* Adding contract for returning Error objects as per LanguageService "protocol"
* Fixes throughout codebase to send only error message in error cases
Cleanup of CredentialServiceTest unit test class
Adding standard error handling for event flow validator
* Adding optional data field as per protocol spec
https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md
* Adding optional validation for error objects
The goal of this make sure that test code is correctly organized to ensure that test suites aren't dependent on each other.
* UnitTests get their own project now (renaming Microsoft.SqlTools.ServiceLayer.Test to Microsoft.SqlTools.ServiceLayer.UnitTests) which is about 90% of the changes to the files.
* IntegrationTests no longer depends on UnitTests, only Test.Common
* Any shared components from TestObjects that spins up a "live" connection has been moved to IntegrationTests Utility/LiveConnectionHelper.cs
* The dictionary-based mock file stream factory has been moved to Test.Common since it is used by UnitTests and IntegrationTests
* Added a overload that doesn't take a dictionary for when we don't care about monitoring the storage (about 90% of the time)
* The RunIf* wrapper methods have been moved to Test.Common
* OwnerUri and StandardQuery constants have been moved to Test.Common Constants file
* Updating to latest SDK version available at https://www.microsoft.com/net/core#windowscmd
* Moving unit tests to unit test folder
* Changing namespaces to UnitTests
* Moving some constants and shared functionality into common project, making the UnitTests reference it
* Unit tests are working!
* Integration tests are working
* Updating automated test runs
* Fixing one last broken unit test
* Exposing internals for other projects
* Moving edit data tests to UnitTest project
* Applying refactor fixes to unit tests
* Fixing flaky test that wasn't awaiting completion
