* Remove unnecessary 'use strict' lines and add hygiene check for them
* Move check to under tslint filters to reduce number of filters needed
* Only take first 10 lines of file
* Fixed#4772 create unique connection for each notebook by using notebook path as uri
Disconnect sqlConnection from SqlKernel to ensure no connection left after the notebook is closed.
* SqlSessionManager is ADS level manager
* Moved path to SqlKernel constructor
This is a partial fix that lays groundwork for full "Prompt to connect" if a kernel needs a connection.
I am waiting on Yurong's refactoring of connection handling before doing any of the prompt work.
- Adds kernel metadata about whether a connection is required.
- For Jupyter, only Spark kernels are listed as requiring a connection
- If this is true and there's no active connection, will show notification and not call execute
In the future, this path will still be used if user is prompted to connect and cancels out.
The future change will be to inject a "connect" handler from notebook.component to the cell callback and use to set connection context
* Fixed#4800 need to use ConnectionProfile in order to get the correct connection
* Go back to create connect in run cell to avoid to fail to run cell or close the connection used by other.

* Fix#4356 New Notebook from connection doesn't connect
Fix new notebook error by passing profile instead of ID.
- I could've just sent the ID over, but this fix sets the stage for disconnected connections to work (since we have enough info to properly connect).
- There's a bug in NotebookModel blocking the disconnected connection part working, but Yurong's in progress fixes will unblock this. Hence checking in as-is and working to properly unblock once that's in.
* Support connection profile in commandline service
- Added new context API for things that want to work on commandline and object explorer
- Refactored commandlineservice slightly to be async & have a simpler execution flow (far fewer if/else statements)
* Fix unit tests
- Fixed 2 issues raised by tests (sholdn't do new query if no profile passed, shouldn't error on new query failing)
- Updated unit tests to pass as expected given changes to the APIs.
* Start single client session based on the default kernel or saved kernel in NB.
* Added kernel displayName to standardKernel.
Modified name to allign wtih Juptyer Kernel.name.
So we can show the displayName during startup and use the name to start the session.
* Change session.OnSessionReady event in KernelDropDown
* Added model.KernelChnaged for switching kernel in the same provider
* Fixed session.Ready sequence
* Fixed merge issues
* Solve merged issue
* Fixed wrong kernel name in saved NB
* Added new event in Model to notify kernel change.
Toolbar depends on ModelReady to load
* Change attachTo to wait for ModelReady like KenelDropDown
* sanitizeSavedKernelInfo to fix invalid kernel and display_name. For example: PySpark1111 and PySpark 1111
* Added _contextsChangingEmitter to change loadContext msg when changing kernel
* Resolve PR comments
- Fixes#4129 Overlapping command help windows in notebook
- Do not show parameter hints for inactive cells, to avoid them hanging around when no longer selected
- Fixes#4116 Notebooks: Intellisense Doesn't Work using Add New Connection
- Move connect/disconnect logic to 1 place (code component) instead of 2
- Handle the case where you connect after choosing active cell. We now hook to the event and update connection
- Fix issues in sql session manager where result outputs 0 rows. This was failing to show the empty resultset contents, which is a regression vs. query editor. It also put unhandled error on the debug console
- Fix#3913 Notebook: words selected in other cells should be unselected on cell change
Note: after fix, now looks as follows. Need to do follow up to get correct grid min height

* Move to using notebook language by default, with override in cell
* Update cell language on kernel change
* Tweak language logic so that it prefers code mirror mode, then falls back since this was failing some notebooks
* Add new package.json contribution to define language magics. These result in cell language changing. Language is cleared out on removing the language magic
* Added support for executing Python, R and Java in the SQL Kernel to prove this out. It converts to the sp_execute_external_script format
TODO in future PR:
* Need to hook up completion item support for magics (issue #4078)
* Should add indicator at the bottom of a cell when an alternate language has been detected (issue #4079)
* On executing Python, R or Java, should add some output showing the generated code (issue #4080)
* Greatly reduce time to generate html table string
* change outer tag to table instead of html
* address PR feedback for more descriptive variable name
- Fix#3844
- Fix#3955
- Specs can be null on early load of Jupyter kernels
- Cells were missing in some reference test .ipynb files. We should be resilient to malformed files if possible.
* Fixed#3954
The problem is: connectionProfileId is not passed into New Notebook flow.
The fix is: plumbing connectionProfileId via NotebookInput.
* Resolved PR comments
* Fix#3985 Hide cell toolbar for markdown cells
* Note that I'm still hiding the overall toolbar section per UX feedback
* Also now hiding line numbers per UX feedback..
Fixes#3931
- Align run button correctly so it's centered in new cell
- Refactor to support multi-state button.
- Hidden state is set to show execution count
- Stopped state shows run button
- Running state shows stop button
- Error state (will) show error button. This isn't fully handled right now
- Add execution count to model and to SqlKernel, verify serialization, loading, update matches other notebook viewers
**Notes on implementation**:
I think this is a decent solution for a) showing execution count as text, and b) perfectly centering the run button.
The below solution shows count correctly up to 999 runs (that’s clicking 999 times in a single session), the icon lines up juuust about right with [ ] but for other numbers it is pretty close but probably not exactly right. I wish I could solve this to work better but trying to change text float to center etc. really isn’t working.
**Screenshots**:

With running cell:

- Handles empty file scenario, with fixes along the way for missing metadata (bonus win)
- In non-empty file still shows error and kernel stuck in loading state. #3964 opened to track this issue and fix later
This was reviewed / worked on with Smitha and will be signed off on by PM via mail.
1 thing left (make run button look better when not selected) will be one in separate review.
Changes
- Add top/bottom padding to editor so it's not cramped
- Added an (on by default) setting `notebook.overrideEditorTheming`. This controls whether new colors etc. are used for notebook editors or if users should see vanilla UI like in standard editor. Settings under this flag are:
- When unselected, editor has same color as toolbar. On selection it goes back to regular editor view so colors work "right"
- In standard light/dark themes we now use a filled in background color instead of border box.
- SQLKernel is the only place to listen for batch and query complete messages now
- It routes to the 1 and only future (since can only have 1 at a time
- It handles query cancelation and not-connected issues correctly
