# Summary of the Pull Request
This PR will allow the cursor to be double width when on top of a double width character. This required changing `IsCursorDoubleWidth` to check whether the glyph the cursor's on top of is double width. This code is exactly the same as the original PR that addressed this issue in #2932. That one got reverted at some point due to the crashes related to it, but due to a combination of Terminal having come further since that PR and other changes to address use-after-frees, some of the crashes may/may not be relevant now. The ones that seemed to be relevant/repro-able, I attempt to address in this PR.
The `IsCursorDoubleWidth` check would fail during the `TextBuffer::Reflow` call inside of `Terminal::UserResize` occasionally, particularly when `newCursor.EndDeferDrawing()` is called. This is because when we tell the newCursor to `EndDefer`, the renderer will attempt to redraw the cursor. As part of this redraw, it'll ask if `IsCursorDoubleWidth`, and if the renderer managed to ask this before `UserResize` swapped out the old buffer with the new one from `Reflow`, the renderer will be asking the old buffer if its out-of-bounds cursor is double width. This was pretty easily repro'd using `cmatrix -u0` and resizing the window like a madman.
As a solution, I've moved the Start/End DeferDrawing calls out of `Reflow` and into `UserResize`. This way, I can "clamp" the portion of the code where the newBuffer is getting created and reflowed and swapped into the Terminal buffer, and only allow the renderer to draw once the swap is done. This also means that ConHost's `ResizeWithReflow` needed to change slightly.
In addition, I've added a WriteLock to `SetCursorOn`. It was mentioned as a fix for a crash in #2965 (although I can't repro), and I also figured it would be good to try to emulate where ConHost locks with regards to Cursor operations, and this seemed to be one that we were missing.

## Validation Steps Performed
Manual validation that the cursor is indeed chonky, added a test case to check that we are correctly saying that the cursor is double width (not too sure if I put it in the right place). Also open to other test case ideas and thoughts on what else I should be careful for since I am quite nervous about what other crashes might occur.
## Summary of the Pull Request
When WSL vim prints the initial empty buffer (the one that's just a bunch of '\~'s), it prints this by doing the following:
* Print '\~' followed by enough spaces to clear the line
* Use CUP (`^[[H`) to move the cursor to the start of the next line
* repeat until the buffer is full
When we'd get the line of "\~ "... in conhost, we'd mark that line as wrapped.
Logically, it doesn't really make any sense that when we follow that up by moving the cursor, the line is wrapped. However, this is just how conhost is right now.
This wasn't ever a problem in just conhost before, because we really didn't care if lines in the alt buffer were "wrapped" or not. Plus, when vim would get resized, it would just reprint it's own buffer anyways. Nor was this a problem in conpty before this year (2020). We've only just recently added logic to conpty to try and preserve wrapped lines.
Initially, I tried fixing this by breaking the line manually when the cursor was moved. This seemed to work great, except for the win32 vim.exe. Vim.exe doesn't emit a newline or a CUP to get to the next line. It just _goes for it_ and keeps printing. So there's _no way_ for us to know the line broke, because they're essentially just printing one long line, assuming we'll automatically move the cursor.
So instead, I'm making sure to emit the proper number of spaces at the end of a line when the line is wrapped. We won't do any funny business in that scenario and try to optimize for them, we'll _just print the spaces_.

If an application writes to the screen while not in VT mode, and the
user has scrolled forward in the screen buffer, the _virtual bottom_
location is not updated to take that new content into account. As a
result, the viewport can later jump back to the previous _virtual
bottom_, making the content disappear off screen. This PR attempts to
fix that issue by updating the _virtual bottom_ location whenever the
cursor moves below that point.
## PR Checklist
* [x] CLA signed.
* [x] Tests added/passed
## Detailed Description of the Pull Request / Additional comments
This simply adds a condition in the
`SCREEN_INFORMATION::SetCursorPosition` to check if the new _Y_
coordinate is below the current _virtual bottom_, and if so, updates the
_virtual bottom_ to that new value.
I considered trying to make it only update when something is actually
written to the screen, but this seemed like a cleaner solution, and is
less likely to miss out on a needed update.
## Validation Steps Performed
I've manually tested the case described in issue #5302, and confirmed
that it now works as expected. I've also added a unit test that checks
the virtual bottom is updated correctly under similar conditions.
Closes#5302
This fixes an issue where a shift+click selection with `copyOnSelect`
enabled would result in copying the content as a single line.
## Detailed Description of the Pull Request / Additional comments
I've been thinking a lot about this issue and how it relates to the
copy/paste discussions we've been having over the past few weeks.
Considering that the majority of users want regular copy, it makes sense
to default to that in this case too.
If a user wants to perform a special form of copy, it makes sense that
they should use their custom keybinding to accomplish that. This kind of
behavior aligns with that kind of philosophy.
## Validation Steps Performed
The following scenarios were tested with `copyOnSelect` enabled.
| scenario | behavior |
|-----------------------------------------|-------------------------------|
| Perform a shift+click selection | content copied w/ newlines |
| right-click | clipboard paste |
| copy keybinding (`singleLine` disabled) | content copied w/ newlines |
| copy keybinding (`singleLine` enabled) | content copied as single line |

## Summary of the Pull Request
Renderer: Add support for backoff and auto-disable on failed retry
This commit introduces a backoff (150ms * number of tries) to the
renderer's retry logic (introduced in #2830). It also changes the
FAIL_FAST to a less globally-harmful render thread disable, so that we
stop blowing up any application hosting a terminal when the graphics
driver goes away.
In addition, it adds a callback that a Renderer consumer can use to
determine when the renderer _has_ failed, and a public method to kick it
back into life.
Fixes#5340.
This PR also wires up TermControl so that it shows some UI when the renderer tastes clay.
## PR Checklist
* [x] Closes#5340
* [x] cla
* [ ] Tests added/passed
* [ ] Requires documentation to be updated
* [x] I've discussed this with core contributors already.
## Validation Steps Performed
I tested this by dropping the number of retries to 1 and forcing a TDR while doing `wsl cmatrix -u0`. It picked up exactly where it left off.
As a bonus, you can actually still type into the terminal when it's graphically suspended (and `exit` still works.). The block is _entirely graphical_.
We received a request from our localization team to switch from
printf-style format strings (%s, %u) to format strings with positional
argument support. I've been hoping for a long time to take a dependency
on C++20's std::format, but we're just not somewhere we can do that.
Enter fmt. fmt is _exactly_ the library we need.
Minor comparison:
std::wstring_view world = /* ... */;
auto str{ wil::str_printf<std::wstring>(L"hello %.*s",
gsl::narrow_cast<size_t>(world.size()),
world.data()) };
---
auto str{ fmt::format(L"hello {0}", world) };
If you really want to use the print specifiers:
auto str{ fmt::printf(L"hello %s", world) };
It's got optional compile-time checking for format strings and is
MIT-licensed. Eventually, we should be able to replace fmt:: with std::
and end up pretty much where we left off.

## Summary of the Pull Request
Adjusts DirectX renderer to use `til::bitmap` to track invalidation
regions. Uses special modification to invalidate a row-at-a-time to
ensure ligatures and NxM glyphs continue to work.
## References

* [x] Automated tests for `til` changes.
* [x] Am core contributor. And discussed with @DHowett-MSFT.
## Detailed Description of the Pull Request / Additional comments
- Applies `til::bitmap` as the new invalidation scheme inside the
DirectX renderer and updates all entrypoints for collecting
invalidation data to coalesce into this structure.
- Semi-permanently routes all invalidations through a helper method
`_InvalidateRectangle` that will expand any invalidation to cover the
entire line. This ensures that ligatures and NxM glyphs will continue
to render appropriately while still allowing us to dramatically reduce
the number of lines drawn overall. In the future, we may come up with
a tighter solution than line-by-line invalidation and can modify this
helper method appropriately at that later date to further scope the
invalid region.
- Ensures that the `experimental.retroTerminalEffects` feature continues
to invalidate the entire display on start of frame as the shader is
applied at the end of the frame composition and will stack on itself
in an amusing fashion when we only redraw part of the display.
- Moves many member variables inside the DirectX renderer into the new
`til::size`, `til::point`, and `til::rectangle` methods to facilitate
easier management and mathematical operations. Consequently adds
`try/catch` blocks around many of the already-existing `noexcept`
methods to deal with mathematical or casting failures now detected by
using the support classes.
- Corrects `TerminalCore` redraw triggers to appropriately communicate
scrolling circumstances to the renderer so it can optimize the draw
regions appropriately.
- Fixes an issue in the base `Renderer` that was causing overlapping
scroll regions due to behavior of `Viewport::TrimToViewport` modifying
the local. This fix is "good enough" for now and should go away when
`Viewport` is fully migrated to `til::rectangle`.
- Adds multiplication and division operators to `til::rectangle` and
supporting tests. These operates will help scale back and forth
between a cell-based rectangle and a pixel-based rectangle. They take
special care to ensure that a pixel rectangle being divided downward
back to cells will expand (with the ceiling division methods) to cover
a full cell when even one pixel inside the cell is touched (as is how
a redraw would have to occur).
- Blocks off trace logging of invalid regions if no one is listening to
optimize performance.
- Restores full usage of `IDXGISwapChain1::Present1` to accurately and
fully communicate dirty and scroll regions to the underlying DirectX
framework. This additional information allows the framework to
optimize drawing between frames by eliminating data transfer of
regions that aren't modified and shuffling frames in place. See
[Remarks](https://docs.microsoft.com/en-us/windows/win32/api/dxgi1_2/nf-dxgi1_2-idxgiswapchain1-present1#remarks)
for more details.
- Updates `til::bitmap` set methods to use more optimized versions of
the setters on the `dynamic_bitset<>` that can bulk fill bits as the
existing algorithm was noticeably slow after applying the
"expand-to-row" helper to the DirectX renderer invalidation.
- All `til` import hierarchy is now handled in the parent `til.h` file
and not in the child files to prevent circular imports from happening.
We don't expect the import of any individual library file, only the
base one. So this should be OK for now.
## Validation Steps Performed
- Ran `cmatrix`, `cmatrix -u0`, and `cacafire` after changes were made.
- Made a bunch of ligatures with `Cascadia Code` in the Terminal
before/after the changes and confirmed they still ligate.
- Ran `dir` in Powershell and fixed the scrolling issues
- Clicked all over the place and dragged to make sure selection works.
- Checked retro terminal effect manually with Powershell.

## Summary of the Pull Request
When a pane is closed by a connection, we want to wait until the connection is actually `Closed` before we fire the actual `Closed` event. If the connection didn't close gracefully, there are scenarios where we want to print a message to the screen.
However, when a pane is closed by the UI, we don't really care to wait for the connection to be completely closed. We can just do it whenever. So I've moved that call to be on a background thread.
## PR Checklist
* [x] Closes#1996
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated
## Detailed Description of the Pull Request / Additional comments
Previously we'd wait for the connection to close synchronously when closing tabs or panes. For misbehaving applications like `ssh.exe`, that could result in the `Close` needing to `WaitForSingleObject` _on the UI thread_. If the user closed the tab / pane either with a keybinding or with some other UI element, they don't really care to see the error message anymore. They just want the pane closed. So there's no need to wait for the actual connection to close - the app can just continue on with whatever it was doing.
## Validation Steps Performed
Messed around with closing tabs, panes, tabs with many panes, the entire window. Did this with keybindings, or by clicking on the 'x' on the tab, the 'x' on the window, or using middle-click.
I'm always scared of things like this, so there's a 50% chance this makes things horribly worse.
## Summary of the Pull Request

I was mainly looking for two things:
- the key/value pair is found and read
- the value did not change before/after the pair was read
This pull request makes sure we still get a usable (for troubleshooting purposes) version number in the about dialog and settings file when the user is running unpackaged.
This introduces a magic LCID constant (0x0409).B y default, Package ES emits
version resource information that says we're localized to ... language zero.
It also emits a language-coded version block for 0x0409 (en-US).
These two things cannot both be true. Collapse the wave function by hardcoding
0x0409.
This adds support for the VT escape sequence that requests the
terminal's operating status. There is no attempt to actually verify the
status of the app, though. We always return a response indicating a good
operating condition (the same as most terminal emulators).

## Detailed Description of the Pull Request / Additional comments
This required an update to the `OutputStateMachineEngine` to accept the
`DSR-OS` type, since it only dispatches types that it recognises (I
think that's unnecessary, but that's an issue for another day).
The actual processing of the request is handled in the `AdaptDispatch`
class, where it simply responds with a hard coded sequence (`CSI 0 n`),
indicating a good operating condition.
## Validation Steps Performed
I've added unit tests to confirm that the request is dispatched
correctly, and the appropriate response is returned. I've also manually
confirmed that the test of the _Device Status Report_ in _Vttest_ is now
succeeding.

Now that the Terminal is doing a better job of actually marking which
lines were and were not wrapped, we're not always copying lines as
"wrapped" when they should be. We're more correctly marking lines as not
wrapped, when previously we'd leave them marked wrapped.
The real problem is here in the `ScrollFrame` method - we'd manually
newline the cursor to make the terminal's viewport shift down to a new
line. If we had to scroll the viewport for a _wrapped_ line, this would
cause the Terminal to mark that line as broken, because conpty would
emit an extra `\n` that didn't actually exist.
This more correctly implements `ScrollFrame`. Now, well move where we
"thought" the cursor was, so when we get to the next `PaintBufferLine`,
if the cursor needs to newline for the next line, it'll newline, but if
we're in the middle of a wrapped line, we'll just keep printing the
wrapped line.
A couple follow up bugs were found to be caused by the same bad logic.
See #5039 and #5161 for more details on the investigations there.

When the connection printed text immediately, synchronously, as part of
Start() it would cause terminal to deadlock. We should start the
connection outside of lock.
The ConptyConnection would do this when it failed to launch something
(trivial repro: `wt -- xyz`).
The TelnetConnection would do this all the time, because local loopback
telnet is fast and easy.
This commit introduces another template replacement for the user's
default settings, COMMAND_PROMPT_LOCALIZED_NAME, which will be replaced
with the contents of the CommandPromptDisplayName resource.
By default, that will be "Command Prompt." This name change will apply
only for new users, and only on first launch. Changes in the system
locale after first launch will not impact the name of the profile.
If the user _removes_ the name from their command prompt profile, its
name will revert irrecoverably to "Command Prompt". They will not be
given a chance to regenerate a localized name.

But we really know that `dark` is the one we care about here 😉
My basic idea was that `WM_CHAR` is just the better `WM_KEYDOWN`.
The latter fails to properly support common dead key sequences like in
#3516.
As such I added some logic to `Terminal::SendKeyEvent` to make it return
false if the pressed key represents a printable character.
This causes us to receive a character event with a (hopefully) correctly
composed code unit, which then gets sent to `Terminal::SendCharEvent`.
`Terminal::SendCharEvent` in turn had to be modified to support
potentially pressed modifier keys, since `Terminal::SendKeyEvent` isn't
doing that for us anymore.
Lastly `TerminalInput` had to be modified heavily to support character
events with modifier key states. In order to do so I merged its
`HandleKey` and `HandleChar` methods into a single one, that now handles
both cases.
Since key events will now contain character data and character events
key codes the decision logic in `TerminalInput::HandleKey` had to be
rewritten.

This pull request introduces unexpanded variables (`%DEFAULT_PROFILE%`,
`%VERSION%` and `%PRODUCT%`) to the user settings template and code to
expand them.
While doing this, I ran into a couple things that needed to widen from
accepting strings to accepting string views. I also had to move
application name and version detection up to AppLogic and expose the
AppLogic singleton.
The dynamic profile generation logic had to be moved to before we inject
the templated variables, as the new default profile depends on the
generated dynamic profiles.

The terminal lock is really only for the terminal; since the renderer is
fully owned by the control, not the Terminal, and we'll only be
receiving swap chain events after we register them during
initialization, we don't need to lock before _or_ after firing off the
coroutine.

## Detailed Description of the Pull Request / Additional comments
I've added a condition at the start of the `AdaptDispatch::HardReset` method to check whether we're using the alt buffer, and if so, call the `ConGetSet::PrivateUseMainScreenBuffer` API to switch back to the main buffer.
Calling `AdaptDispatch::UseMainScreenBuffer` would probably be neater for this, but it would also attempt to restore the cursor state, which seems pointless when we're in the process of resetting everything anyway.
## Validation Steps Performed
I've added a screen buffer test to confirm that the `RIS` sequence does actually switch back to the main buffer. I've also manually confirmed that the test case in issue #3685 does now behave as expected.
A side effect of the `SetConsoleCursorInfo` API is that it resets the
cursor type to _Legacy_. This makes it impossible to change the cursor
visibility via the console APIs without also resetting the user's
preferred cursor type. This PR attempts to fix that limitation, by only
resetting the cursor type if the size has also been changed.
## PR Checklist
* [x] Closes#4124
* [x] CLA signed
* [ ] Tests added/passed
* [ ] Requires documentation to be updated
## Detailed Description of the Pull Request / Additional comments
I suspect the reason for the original behaviour was because the
`SetConsoleCursorInfo` API sets both the visibility and the size, and if
you're setting the size, it's assumed you'd want the _Legacy_ cursor
type, because that's the only style for which the size is applicable.
So my solution was to only reset the cursor type if the requested cursor
size was actually different from the current size. That should be
reasonably backwards compatible with most size-changing code, but also
allow for changing the visibility without resetting the cursor type.
## Validation Steps Performed
I've tested the example code from issue #4124, and confirmed that it now
works correctly without resetting the cursor type.
I've also tested the console's _mark mode_, which temporarily changes
the cursor size while selecting. I've confirmed that the size still
changes, and that the original cursor type is restored afterwards.

API remains unchanged. Things are not broken.
## Summary of the Pull Request
Minor cleanup on the schema. Globals isn't accepted anymore,
so the schema should not help you autocomplete anymore.
## Validation Steps Performed
Imported the new schema. You do _not_ get a warning when globals
is in. But, the schema won't suggest things when inside globals.
It's just treated as an unknown item.
However, "defaultProfile" is still required (more of a sanity test)
## Summary of the Pull Request
In preparation for getting more accessibility-related issues, I added an ID to the `ScreenInfoUiaProvider` (SIUP) and abstracted the one from `UiaTextRange`. Using this, I noticed that we are creating SIUPs when a new tab/pane is created. This is _good_. This means that we need to somehow notify a UIA Client that out structure has changed, and we need to use the new SIUP because the old one has been removed.
I'll be investigating that more after this PR lands.
Because we cannot set RequestedTheme at the application level, we
occasionally run into issues where parts of our UI end up themed
incorrectly. Dialogs, for example, live under a different Xaml root
element than the rest of our application. This makes our popup menus and
buttons "disappear" when the user wants Terminal to be in a different
theme than the rest of the system. This hack---and it _is_ a
hack--walks up a dialog's ancestry and forces the theme on each element
up to the root. We're relying a bit on Xaml's implementation details
here, but it does have the desired effect.
It's not enough to set the theme on the dialog alone.
Fixes#3654.
Fixes#5195.
## Summary of the Pull Request
Added `splitMode` to settings schema JSON and md files.
The definition might need some tweaking.

## Summary of the Pull Request
`TrimWhitespace` is misleading. So it is now renamed as 'singleLine'. If true, it comes out as a single line! That makes more sense!

Attempted the keybinding with both settings (and none set).
Attempted mouse copy with and without shift.

When conpty is in VT input mode, we pass through all the input we receive. This includes all the other `Action*Dispatch` methods, but missed this one.

## Detailed Description of the Pull Request / Additional comments
This will fix the <kbd>ctrl+alt+space</kbd> in the Terminal thing mentioned in #4192, but doesn't actually resolve the root cause of that bug (which is tracked in #5205).
## Summary of the Pull Request
When we're restoring from minimized, that `MonitorFromWindow` call is returning null. Curious that we're getting null here, when [MSDN states](https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-monitorfromwindow):
> If the window is currently minimized, MonitorFromWindow uses the rectangle of the window before it was minimized.
Turns out, `MONITOR_DEFAULTTONEAREST` just fixes this.

Verified manually
_Technically_, "wether" is a word but I'd be shocked if there's a scenario for
us to use it properly in this repo, so I'm pulling it from the dictionary.
Also, in #5200, we added "VTE", which is totally a valid acronym, to the codebase,
but not the whitelist. I'm not sure why the bot let me merge it anyways, but I'm
fixing it now.
