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
