It's an overhaul of the Save As mechanism to utilize the file reader/writer classes to better align with the patterns laid out by the rest of the query execution. Why make this change? This change makes our code base more uniform and adherent to the patterns/paradigms we've set up. This change also helps with the encapsulation of the classes to "separate the concerns" of each component of the save as function.
* Replumbing the save as execution to pass the call down the query stack as QueryExecutionService->Query->Batch->ResultSet
* Each layer performs it's own parameter checking
* QueryExecutionService checks if the query exists
* Query checks if the batch exists
* Batch checks if the result set exists
* ResultSet checks if the row counts are valid and if the result set has been executed
* Success/Failure delegates are passed down the chain as well
* Determination of whether a save request is a "selection" moved to the SaveResultsRequest class to eliminate duplication of code and creation of utility classes
* Making the IFileStream* classes more generic
* Removing the requirements of max characters to store from the GetWriter method, and moving it into the constructor for the temporary buffer writer - the values have been moved to the settings and given defaults
* Removing the individual type writers from IFileStreamWriter
* Removing the individual type writers from IFIleStreamReader
* Adding a new overload for WriteRow to IFileStreamWriter that will write out data, given a row's worth of data and the list of columns
* Creating a new IFileStreamFactory that creates a reader/writer pair for reading from the temporary files and writing to CSV files
* Creating a new IFileStreamFactory that creates a reader/writer pair for reading from the temporary files and writing to JSON files
* Dramatically simplified the CSV encoding functionality
* Removed duplicated logic for saving in different types and condensed down to a single chain that only differs based on what type of factory is provided
* Removing the logic for managing the list of save as tasks, since the ResultSet now performs the actual saving work, there's no real need to expose the internals of the ResultSet
* Adding new strings to the sr.strings file for save as error messages
* Completely rewriting the unit tests for the save as mechanism. Very fine grained unit tests now that should cover majority of cases (aside from race conditions)
* Refactoring maxchars params into settings and out of file stream factory
* Removing write*/read* methods from file stream readers/writers
* Migrating the CSV save as to the resultset
* Tweaks to unit testing to eliminate writing files to disk
* WIP, moving to a base class for save results writers
* Everything is wired up and compiles
* Adding unit tests for CSV encoding
* Adding unit tests for CSV and Json writers
* Adding tests to the result set for saving
* Refactor to throw exceptions on errors instead of calling failure handler
* Unit tests for batch/query argument in range
* Unit tests
* Adding service integration unit tests
* Final polish, copyright notices, etc
* Adding NULL logic
* Fixing issue of unicode to utf8
* Fixing issues as per @kburtram code review comments
* Adding files that got broken?
This basically is a replacement to the fix for Adding Milliseconds to DateTime fields. I didn't take into consideration that `DATE` columns would report as DateTime type. Date columns have a numeric scale set to 255, leading to the formatting string for the date time to include 255 millisecond places, which is invalid.
This change also reverses the change to store DateTime precision in the buffer file. Instead, the column metadata is now used when deserializing the rows from the db. `DATETIME` and `DATETIME2` columns are differentiated by their numeric scale while `DATE` columns are differentiated by their datatype name field.
More unit tests were added. Additionally, this fixes an unreported bug that `DATE` columns were being displayed with times, which is incorrect.
* Revert "Adding Milliseconds to DateTime fields (#173)"
This reverts commit 431dfa4156.
* Reworking the reader to use the column metadata for date types
* DbColumn -> DbColumnWrapper
* Fina tweaks to support DATETIME2(0)
* Removing the unused arguments
* DbColumn and ReliableConnection tests
* More retry connection tests
* More tests
* Fix broken peek definition integration tests
* Fix test bug
* Add a couple batch tests
* Add some more tests
* More tests for code coverage.
* Validation and Diagnostic tests
* A few more tests
* A few mote test changes.
* Update file path tests to run on Windows only
This is a slightly larger change than anticipated due the difference between `DATETIME`, `DATETIME2`, and `DateTime`. The `DATETIME` type always uses 3 decimal points of a second, while the `DATETIME2` type has 7 (although since `DATETIME2(7)` is default in SSMS suggesting that it is a variable precision type). Regardless of the db type, the engine returns `DateTime` C# type. The db types are only made visible via the column info, via the numeric precision and numeric scale. My findings were as such:
`DATETIME `: Precision = 23, Scale = 3
`DATETIME2`: Precision = 255, Scale = 7
The scale corresponds neatly with the number of second decimal points to show. The buffer file writer was modified to store both the scale and the number of ticks. Then the buffer file reader was modified to read in the precision and the number of ticks and generate the ToString version of the DateTime to add "f" as many times as there is scale, which corresponds to milliseconds.
* Code for writing milliseconds of datetime/datetime2 columns
* Adding unit tests
* Fixing potential bug with datetime2(0)
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
Next round of code coverage test cases. Please review the commit for next iteration.

Note: This feature contains changes that will break the contract for
saving as CSV and JSON. On success, null is returned as a message instead
of "Success". Changes will be made to the vscode component to handle this
change.
