* Fix#4029 Ensure changeKernels always resolves, even in error states
This is necessary to unblock reverting the kernel on canceling Python install
- startSession now correctly sets up kernel information, since a kernel is loaded there.
- Remove call to change kernel on session initialize. This isn't needed due to refactor
- Handle kernel change failure by attempting to fall back to old kernel
- ExtensionHost $startNewSession now ensures errors are sent across the wire.
- Update AttachTo and Kernel dropdowns so they handle kernel being available. This is needed since other changes mean the session is likely ready before these get going
* Fix to handle python cancel and load existing scenarios
- Made changes to handle failure flow when Python dialog is canceled
- Made changes to handle initial load fail. Kernel and Attach To dropdowns show No Kernel / None and you can choose a kernel
- Added error wrapping in ext host so that string errors make it across and aren't lost.
* Fix#4452 Notebook is reloaded with wrong kernel
- Await all extension registration before getting providers and providerId
To do this, we need to await way up in the NotebookInput, and promise the model that we'll have values eventually
* #4339: Kernel change event occurs after model load
* #4347: Code cleanup - Notebooks Save
* Remove save method from sqlops
* Adding save method to api's
* Adding save method to ext host
* Misc change
* 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)

- 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.
- Editor layout gets called sometimes when other events happen (and Notebook isn't visible)
- Add in a layout call on re-setting input so the cell is updated. This fixes the problem by laying out once the UI is visible again.
Note: long term, should really be destroying the UI (while preserving the model), then restoring it including scroll selection etc. and hooking back up to the model. That is... much more work, but something we'll need long term to avoid issues where we have many Notebooks open at once. Not in scope for this PR
- Added `runCell` API. Updated runCell button to listen to events on the model so it'll reflect run cell when called from other sources
- Plumbed through kernelspec info to the extension side so when changed, it's updated
- Fixed bug in ConnectionProfile where it didn't copy from options but instead overrode with empty wrapper functions
Here's the rough test code (it's in the sql-vnext extension and will be out in a separate PR)
```ts
it('Should connect to local notebook server with result 2', async function() {
this.timeout(60000);
let pythonNotebook = Object.assign({}, expectedNotebookContent, { metadata: { kernelspec: { name: "python3", display_name: "Python 3" }}});
let uri = writeNotebookToFile(pythonNotebook);
await ensureJupyterInstalled();
let notebook = await sqlops.nb.showNotebookDocument(uri);
should(notebook.document.cells).have.length(1);
let ran = await notebook.runCell(notebook.document.cells[0]);
should(ran).be.true('Notebook runCell failed');
let cellOutputs = notebook.document.cells[0].contents.outputs;
should(cellOutputs).have.length(1);
let result = (<sqlops.nb.IExecuteResult>cellOutputs[0]).data['text/plain'];
should(result).equal('2');
try {
// TODO support closing the editor. Right now this prompts and there's no override for this. Need to fix in core
// Close the editor using the recommended vscode API
//await vscode.commands.executeCommand('workbench.action.closeActiveEditor');
}
catch (e) {}
});
it('Should connect to remote spark server with result 2', async function() {
this.timeout(240000);
let uri = writeNotebookToFile(expectedNotebookContent);
await ensureJupyterInstalled();
// Given a connection to a server exists
let connectionId = await connectToSparkIntegrationServer();
// When I open a Spark notebook and run the cell
let notebook = await sqlops.nb.showNotebookDocument(uri, {
connectionId: connectionId
});
should(notebook.document.cells).have.length(1);
let ran = await notebook.runCell(notebook.document.cells[0]);
should(ran).be.true('Notebook runCell failed');
// Then I expect to get the output result of 1+1, executed remotely against the Spark endpoint
let cellOutputs = notebook.document.cells[0].contents.outputs;
should(cellOutputs).have.length(4);
let sparkResult = (<sqlops.nb.IStreamResult>cellOutputs[3]).text;
should(sparkResult).equal('2');
try {
// TODO support closing the editor. Right now this prompts and there's no override for this. Need to fix in core
// Close the editor using the recommended vscode API
//await vscode.commands.executeCommand('workbench.action.closeActiveEditor');
}
catch (e) {}
});
});

- Fixes#3197 Notebooks: builtin provider always used on reopen with notebook file visible
- Fixes#3414 Can't refresh kernel after connect to big data cluster
There are 3 parts to this fix:
- If no notebook provider other than the default is installed, we warn users and prompt to install the SQL2019 extension
- We wait on the extension host registration to complete before determining which provider to use
- We know that the extension registration of the provider instance will be after package.json is read, so if we wait after registration for 10 seconds to give this a chance to happen before returning a provider to the front end
* Remove launch.json change that was added accidentally
* Fix timeout not being the expected value

- Add edit API that can be used in the extension
- Separated document and editor classes out since this is the point those get big. I can refactor back in if needed to ease code review
- Based this off text editing APIs but tweaked for the fact this is a cell/array based set of edits
* Allow for cell unselection
* PR Feedback: use event.stopPropagation() when multiple events can fire
* Ensure markdown goes into Preview mode when cell not selected
initial support for Notebook extensibility. Fixes#3148 , Fixes#3382.
## Design notes
The extensibility patterns are modeled after the VSCode Document and Editor APIs but need to be different since core editor concepts are different - for example Notebooks have cells, and cells have contents rather than editors which have text lines.
Most importantly, a lot of the code is based on the MainThreadDocumentsAndEditors class, with some related classes (the MainThreadDocuments, and MainThreadEditors) brought in too. Given our current limitations I felt moving to add 3 full sets of extension host API classes was overkill so am currently using one. Will see if we need to change this in the future based on what we add in the additional APIs
## Limitations
The current implementation is limited to visible editors, rather than all documents in the workspace. We are not following the `openDocument` -> `showDocument` pattern, but instead just supporting `showDocument` directly.
## Changes in this PR
- Renamed existing APIs to make clear that they were about notebook contents, not about notebook behavior
- Added new APIs for querying notebook documents and editors
- Added new API for opening a notebook
- Moved `New Notebook` command to an extension, and added an `Open Notebook` command too
- Moved notebook feature flag to the extension
## Not covered in this PR
- Need to actually implement support for defining the provider and connection IDs for a notebook. this will be important to support New Notebook from a big data connection in Object Explorer
- Need to add APIs for adding cells, to support
- Need to implement the metadata for getting full notebook contents. I've only implemented to key APIs needed to make this all work.
