From 52b5f222dbe4e1f9b7dc678971f5663f03637529 Mon Sep 17 00:00:00 2001 From: Karl Burtram Date: Sat, 8 Oct 2016 19:18:26 +0000 Subject: [PATCH] Merge dev to master for 0.0.7 release (#86) * Disable failing test while investigating * Made connection errors more user-friendly (#57) * Bug/negativeOneRowsAffected strings file fix (#61) * Adding changes to sr.strings files * Fixing bug by changing valid filename check to fail on whitespace (#55) Fixing a bug from the unit tests on OSX/Unix where attempting to create a file with a name that's all whitespace succeeds when it should fail. This was passing in Windows because File.Open throws an ArgumentException when an all whitespace name is provided. In Unix systems, File.Open does not throw, causing the test to fail. Solution is to check for whitespace in the sanity check. * Format Cell Values (#62) * WIP for ability to localize cell values * Changing how DateTimeOffsets are stored, getting unit tests going * Reworking BufferFileStreamWriter to use dictionary approach * Plumbing the DbCellValue type the rest of the way through * Removing unused components to simplify contract * Cleanup and making sure byte[] appears in parity with SSMS * CR comments, small tweaks for optimizing LINQ * Feature/batch line info (#56) * 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 * Remove deleted file with whitespace name * Feature/autocomp options (#63) * Enable IntelliSense settings * Fix up some bugs in the IntelliSense settings. * Code cleans for PR * Fix a couple exceptions that are breaks query execute and intellisense. * Add useLowerCase flag and settings tests * Remove task.wait from test to avoid break on build machine. (#67) This is to fix test breaks so I'll merge now. Please let me know if there are comments on this commit. * Do not use ReliableCommand in the query execution service (#66) * Do not use ReliableCommand in the query execution service. * Fixing the logic to remove InfoMessage handlers from ReliableSqlConnection * Adding test to query UDT * Bump SMO to 140.1.6 to pick up perf fixes (#69) * Enable Quick Info hover tooltips (#65) Pushing to include in tomorrow's partner release build. Please send me any feedback and I'll address in the next Intellisense PR. * Added grouping between system/user dbs when listing (#70) * Feature/timestamp messages (#68) * added support for timestamps * fixed tests * Moved message class to own file; added 'z' to end of date strings * added default time constructor * removed unnecessary z * added time string format info in comment * changed from utc time to using local time * Feature/save selection (#64) * Save selection * Add tests * Change filename in test * Code cleanup * Refactor handler * Code cleanup * Modify tests to have query selection * Change variable declaration * Bump SMO to 14.0.7 to pick Batchparser updates (#72) ...bumping versions. No review needed. * Lingering File Handles (#71) 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 * Add IntelliSense binding queue (#73) * Initial code for binding queue * Fix-up some of the timeout wait code * Add some initial test code * Add missing test file * Update the binding queue tests * Add more test coverage and refactor a bit. Disable reliabile connection until we can fix it..it's holding an open data reader connection. * A few more test updates * Initial integrate queue with language service. * Hook up the connected binding queue into al binding calls. * Cleanup comments and remove dead code * More missing comments * Fix build break. Reenable ReliabileConnection. * Revert all changes to SqlConnectionFactory * Resolve merge conflicts * Cleanup some more of the timeouts and sync code * Address code review feedback * Address more code review feedback * Feature/connect cancel (#74) * 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 * Fix an issue with queue deadlocks causing test failures (#77) * Fixed issue where connecting could take very long and cancellation would not work (#78) * Fixed issue where connecting could take very long and cancellation would not work * Addressing feedback * Remove warning suppression * Adding unlimited timeout for query execution (#76) Adding explicitly setting the timeout for command execution to unlimited. We can change this to be user configurable at a later time * Support 'for XML and for JSON' queries (#75) * Set isXMl and isJson for 'for xml/json' resultSets * Change string comparison * Modify if-else * VSTS 8499785. Close SqlToolsService after VS Code exits. (#80) VSTS 8499785. Close SqlToolsService after VS Code exits. * Remove extra level of tasks in binding queue (#79) * Remove extra layer of tasks in binding queue * Change order of assigning result to avoid race condition * Add timeout log for the metadata lock event * Fix test cases --- .gitignore | 5 + nuget.config | 1 + .../Connection/ConnectionService.cs | 201 ++++- .../Contracts/CancelConnectParams.cs |
