* Merge pane splitting methods
Having separate Horizontal/Vertical versions made it hard to manage, and App.cpp already made use of Pane::SplitState so it made sense to have that be the descriminator
* Rename Tab::(Can)AddSplit to (Can)SplitPane to align with Pane methods
Split was used as a noun in Tab but a verb in Pane, which felt odd
* Remove unused local variable in Pane::_CanSplit
* Remove redundant 'else' branches in Pane
Improves readibility for all 'low hanging fruit' cases where the 'if' was returning.
When the scrollback buffer is empty, the RIS escape sequence (Reset to Initial
State) will fail to clear the screen, or reset any of the state. And when there
is something in the scrollback, it doesn't get cleared completely, and the
screen may get filled with the wrong background color (it should use the
default color, but it actually uses the previously active background color).
This commit attempts to fix those issues.
The initial failure is caused by the `SCREEN_INFORMATION::WriteRect` method
throwing an exception when passed an empty viewport. And the reason it's passed
an empty viewport is because that's what the `Viewport::Subtract` method
returns when the result of the subtraction is nothing. The PR fixes the
problem by making the `Viewport::Subtract` method actually return nothing in
that situation.
This is a change in the defined behavior that also required the associated
viewport tests to be updated. However, it does seem a sensible change, since
the `Subtract` method never returns empty viewports under any other
circumstances. And the only place the method seems to be used is in the
`ScrollRegion` implementation, where the previous behavior is guaranteed to
throw an exception.
The other issues are fixed simply by changing the order in which things are
reset in the `AdaptDispatch::HardReset` method. The call to `SoftReset` needed
to be made first, so that the SGR attributes would be reset before the screen
was cleared, thus making sure that the default background color would be used.
And the screen needed to be cleared before the scrollback was erased, otherwise
the last view of the screen would be retained in the scrollback buffer.
These changes also required existing adapter tests to be updated, but not
because of a change in the expected behaviour. It's just that certain tests
relied on the `SoftReset` happening later in the order, so weren't expecting it
to be called if say the scrollback erase had failed. It doesn't seem like the
tests were deliberately trying to verify that the SoftReset _hadn't_ been
called.
In addition to the updates to existing tests, this PR also add a new screen
buffer test which verifies the display and scrollback are correctly cleared
under the conditions that were previously failing.
Fixes#2307.
On occasion, in certain delegated access scenarios, we'll fail to read
the name of one or more of the user's Azure tenants. We would summarily
explode (because we're being strict about our incoming JSON, and we
didn't know that this was possible.)
Now we'll substitute in an alternate name and present the ID.
Fixes#2249.
* Update src/cascadia/TerminalConnection/AzureConnection.cpp
When we change the client ID, we're going to need to force people to log
in again.
We can do that either by:
1. Trying to log in and refresh the user's token and failing (displaying
a cryptic message like "you aren't on the internet, please get on the
internet"), **OR** by...
2. Getting out ahead of it, detecting when we would have failed for client
ID (and other) reasons, and _not trying at all._
This is option 2.
Refactors the accessibility providers (ScreenInfoUiaProvider and UiaTextRange) into a better separated model between ConHost and Windows Terminal.
ScreenInfoUiaProviderBase and UiaTextRangeBase are introduced. ConHost and Windows Terminal implement their own versions of ScreenInfoUiaProvider and UiaTextRange that inherit from their respective base classes.
WindowsTerminal's ScreenInfoUiaProvider --> TermControlUiaProvider
Since we're rendering with antialiasing enabled, we need to make sure
we're stroking actual pixels; to do that, we need to adjust all of our
coordinates by the StrokeWidth / 2. We're always using a stroke width of
1, so that means 0.5.
While I was here, I took the opportunity to fix the color of the grid
lines. Fixes#543.
This is more trouble than it's worth. We had code before to re-serialize
settings when they changed, to try and gracefully migrate settings from old
schemas to new ones. This is good in theory, but with #754 coming soon, this
is going to become a minefield. In the future we'll just always be providing a
base schema that's reasonable, so this won't matter so much. Keys that users
have that aren't understood will just be ignored, and that's _fine_.
Fixes a crash that can occur when splitting pane that was so small that the target panes would have a width/height of 0, causing DxRenderer to fail when creating the device resources.
This PR prevents both the call to `App::AddHorizontal/VerticalSplit` and the creation of the `TermControl` if the split would fail.
Closes#2401
## Details
`App::_SplitPane` calls `focusedTab->CanAddHorizontalSplit/CanAddHorizontalSplit` before it initializes the `TermControl` to avoid having to deal with the cleanup. If a split cannot occur, it will simply return.
**Question: Should we beep or something here?**
It then follows the same naming/flow style as the split operation, so: `Tab::CanAddHorizontalSplit -> Pane::CanSplitHorizontal ->Pane::_CanSplit`. The public pane methods will handle leaf/child the same as the current Split methods.
`_CanSplit` reuses existing logic like `_root.GetActualWidth/Height`, `Pane::_GetMinSize`, and the `Half` constant.
## Validation Steps Performed
1. Open a new tab
2. Attempt to split horizontally/vertically more than 6-8 times
Success: Pane will will eventually stop splitting rather than crashing the process.

This is based on discussion with @dhowett-msft we had o*line. We're trying to
work through a way to prevent dynamic profiles from roaming to machines the
dynamic profiles might not exist on.
After writing this up, I'm not totally sure that it's a better design.
* Add some initial updates from discussion
* Pushing some updates here. I haven't given it a once over to ensure it's all consistent but it's worth reviewing @dhowett-msft
