8fe6c21ef8 Keep the font size delta across settings reloads (#20230)
This is a trivial fix for an issue we get a somewhat outsized number of
complaints about.

When the user has adjusted the font size in any direction, we'll just
keep track of the magnitude and apply it every time the settings change.

Yes, this means that if you zoom once and then change your real font
size it's going to zoom even more.

That probably doesn't matter.

abeac1b135 Use PlaySoundW for profile bell sounds (#20031)
We believed that this would fix an issue on Windows 10, where the volume
mixer would forget Windows Terminal after every relaunch. It turns out
that it does not.

Still, this code is much more concise and doesn't require yet another
WinRT object. Story of our lives.

12e3455bb2 Make DECSTR cursor restore behave like xterm in alt screen buffer (#20032)
There is some disagreement among terminal emulators as to whether DECSTR
(and therefore, soft reset) restores the cursor in the active buffer or
in all buffers.

We had previously chosen to restore the cursor in all buffers.

xterm restores the cursor only in the active buffer.

fb71a0462e Add safeUriSchemes setting (#20207)
This adds a `safeUriSchemes` global setting which lets you define
hyperlink URI schemes which the user considers safe. No confirmation
dialog will be shown when trying to open hyperlinks which use these
schemes.

- This solves the root issue, but doesn't introduce any UI or
  documentation changes. I wanted to validate the approach and
  implementation with you first.
- I closely followed the code handling the `disabledProfileSources`
  setting, which is of the same type.
- This feature does not change the behavior of `http`, `https` and
  `file` schemes.

Validation

I ran the dev terminal, and tested the behavior by clicking on `vscode`
hyperlinks generated by ripgrep with various `safeUriSchemes` settings:

- Setting not defined - asks for confirmation
- `["vscode"]` - does not ask for confirmation
- `["foo", "vscode"]` - does not ask for confirmation
- `["foo"]` - asks for confirmation
- `null` - asks for confirmation
- `[]` - asks for confirmation
- `[""]` - asks for confirmation
- `[{"foo": "bar"}]` - fails to deserialize (as expected)

A few uinit tests failed, but they seem unrelated to these changes:
- `KeyBindingTests` in `UnitTests_SettingsModel`, probably because I use
  an AZERTY keyboard.
- A few `Conhost` tests, but I didn't touch this part

c829d4ca54 sixel: prevent allocating an absurd amount of memory or writing OOB (#20213)
This commit implements two fixes for the integer overflow/out-of-bounds
write reported in #20149.

First, it catches any exception generated in sixel char processing
(which will prevent `out_of_memory` or `bad_alloc` from being ignored
sight-unseen, and will prevent the consumption of further DCS content).

Second, it prevents us from allocating memory for an image which will
never be displayed (because it exceeds the height of the display.)

This supersedes prior work in #20153 for the same issues.

b991eb048e Only set startingTitle once, clear up title fallback handling (#20214)
This commit ensures that we only set the starting title once when we
open a new terminal pane.

It also consolidates all title selection into Terminal::GetConsoleTitle,
which is now used in the TitleChanged event.

TitleChanged no longer stores a separate copy of the starting title if
an application attempts to _clear_ the title; that seems like a poorer
implementation of what we already had.

This supersedes work in #20204.

a325a2fa5a Fix settings error text legibility in High Contrast mode (#20098)
Closes #18147

`SystemErrorTextColor` doesn't adapt to High Contrast themes, so the
error details in the "Failed to reload settings" dialog are illegible
(yellow on cream in HC White, for example).

Fix: skip the `ErrorTextBrush` foreground override when High Contrast is
active, letting the text inherit the system HC text color from its
parent element. This matches the existing HC detection pattern used in
`TermControl.cpp` and `MainPage.cpp`.

Validated manually on High Contrast White and Night sky themes.

dadde2fb11 fix(resizePane): Mark as handled only when resize succeeds (#20001)
This fix addresses issue #19983 where resizePane actions unconditionally
consume keystrokes even when no resize can occur.

The fix follows the same pattern used for moveFocus and swapPane fixes:
- Changed Tab::ResizePane to return bool indicating success
- Changed TerminalPage::_ResizePane to return bool from ResizePane  
- Updated _HandleResizePane to set args.Handled() based on whether
resize succeeded

This allows the keychord to propagate to the terminal when no resize can
occur, matching the behavior of moveFocus and swapPane (#6129).

Closes #19983

b753e3dee3 Replace confirmCloseAllTabs with confirmOnClose (#20055)
## Summary of the Pull Request
Replaces the `warning.confirmCloseAllTabs` setting with a
`warning.confirmOnClose` enum setting that accepts the following:
- `never`: don't present a warning dialog when closing a session
- `automatic`: present a warning dialog when closing multiple tabs/panes
at once
- `always`: present a warning dialog when closing any session

The confirmation dialog contains a "don't ask me again" checkbox. When
checked, we update the setting to `never`.

This setting also affects the following actions:
- "close other tabs"
- "close tabs after"
- "close other panes"
- "quit"
The appropriate confirmation dialog is shown in these scenarios. We also
present an aggregate dialog instead of prompting the user once per
tab/pane. If there are no other tabs/panes, we don't present a dialog
and treat the key binding as unhandled (passing the key through).

## References and Relevant Issues
Iteration of #19944 

## Validation Steps Performed
- closing a tab:
   -  1 pane --> no dialog
   -  2 panes --> dialog
   -  action and middle clicking tab trigger same flow
- close all other tabs:
   -  no other tabs --> no dialog
   -  1 other tab --> dialog
- close all other panes:
   -  1 pane --> no dialog
   -  2 panes --> dialog
- close all tabs after the current tab:
   -  no tabs after --> no dialog (even if tabs before)
   -  1 tab after --> dialog
- close window:
   -  2 tabs --> dialog
   -  2 panes --> dialog
   -  1 tab with one pane --> no dialog
- Quit the Terminal:
   -  3 windows --> dialog
   - 1 window --> dialog
-  "don't ask me again" checkbox checked --> setting changed to "never"
-  "never" --> no dialog for scenarios above
-  "always" --> dialog always appears, even when closing a single pane

059986ebce [Unpackaged] Fix taskbar glomming due to AUMID (#20064)
The bug was caused by an AUMID mismatch between the Taskbar's .lnk file
and Windows Terminal. Since no AUMID was associated with the .exe, the
OS automatically creates one for us. However, #20018 added an AUMID for
unpackaged scenarios, so now there was a mismatch, resulting in a new
taskbar entry being created.

To fix this, we check if a .lnk points to our .exe in the taskbar.
There's 3 cases here:
1. no .lnk of interest exists --> set the AUMID normally
2. the .lnk carries our AUMID --> set the AUMID normally
3. the .lnk doesn't have an AUMID (aka uses the auto-resolved one) -->
- for this launch: don't set the AUMID so that we both use the
auto-resolved one
- on next launch: set the AUMID on the .lnk and process so that they all
agree

## Validation Steps Performed
In unpackaged folder, move WindowsTerminal.exe to the taskbar (creates
.lnk)...
 Double-click the .exe --> Same taskbar entry is used
 Double-click the .exe _again_ --> second window goes to same taskbar
entry

The first window doesn't have to close for this to work. It just * works
*!

e4e3f08efc Add toast notification infrastructure (#20010)
## Summary of the Pull Request
Adds the infrastructure for toast notifications. Breakdown:
- `DesktopNotification`:
- `DesktopNotificationArgs` includes the struct to group all
notification-related data together.
   - `SendNotification()` actually sends it
- `AppCommandlineArgs.cpp`: added a check for the `--from-toast` no-op
sentinel; ensures no new window is created
- Most of the other changes are just bubbling up the notification from
the `TerminalPaneContent` to `TerminalPage`
- `TabManagement.cpp`: `_SendDesktopNotification()` does the final
packaging of the notification before calling the `DesktopNotification`
API

This supports finding the right tab when it's been reordered or even
moved to a new window!
This also has expanded to support finding the right pane, which is
resilient to pane swaps/closing too. When the pane can't be found, we
just fallback to the tab.
If the pane is already focused, we don't send a notification.

This simply adds the infrastructure! Looks like nothing can actually
take advantage of it yet, but it's been tested with the changes in
#20011.

## Summary of the Pull Request
Changes how/when we display the "restart connection" item in the tab's
context menu. Now, we always display it, but it's disabled if we're not
in a terminal tab.

Applies similar enable/disable logic to the rest of the menu items.

didn't make any sense).

c72600dd4f Add more settings model unit tests (#20117)
## Summary of the Pull Request
Adds tests to `UnitTests_SettingsModel` to improve coverage. Tests
include:
- `SettingInheritanceFallback`: Settings inherit from user defaults;
unset settings fall back to built-in defaults
- `ClearSettingRestoresInheritance`: `ClearXxx()` removes the value at
the current layer, causing fallback to the parent
- `HasSettingAtSpecificLayer`: `HasXxx() `distinguishes explicitly set
values from inherited ones
- `ModifyProfileSettingAndRoundtrip`: Change a profile setting via
setter and `ToJson()` reflects it
- `ModifyGlobalSettingAndRoundtrip`: Change global settings via setter
and `ToJson()` reflects them
- `ModifyColorSchemeAndRoundtrip`: Change a color scheme property and
the serialized JSON reflects it
- `FixupUserSettingsDetectsChanges`: A clean roundtrip produces
idempotent FixupUserSettings() (returns false)
- `FixupCommandlinePatching`: 4 sub-cases: CMD/PowerShell short names
get patched to full paths, no-op when already clean, custom profiles are
untouched

This also updates `TestCloneInheritanceTree` to verify that `HasXxx()`
and settters that modify the clone don't modify the original.

This is being done in preparation for auto-save to help ensure we don't
have any regressions.

## Validation Steps Performed
 Tests pass
 Manually reviewed the new tests, they make sense and do add value
(though some are less valuable than others, admittedly)
 Sent Copilot on a quest to ensure we're not adding redundant tests. It
did catch a few and remove them fwiw.

0a6c3d71fb build: Add a 1ES Pipeline Templates version of Canary (#20127)
This pipeline runs on our agents, rather than OneBranch's, and doesn't
use all of the OneBranch machinery--which is only required for producing
a vpack that we check into Windows. Since Canary will never be a vpack,
we don't need to worry.

It runs at about twice the speed _and_ we control the build images!

This pull request also adds support for the "Terrapin Retrieval Tool,"
which will allow us to move away from having vcpkg contact remote
servers directly to download source code (and which may become mandatory
even in our OneBranch pipelines.)

7a83c0f167 Fix Korean IME overlay hiding characters to the right of cursor (#20041)
This commit fixes a regression in v1.24, where composing Korean text
in-between existing characters causes text to the right to be hidden.
This is problematic for the Korean IME, because it commonly inserts
the composed syllable between existing characters.

The fix compresses (removes/absorbs) available whitespace to the right
of the composition to make space for any existing text. This means
that a composition now virtually acts in insert mode.

Closes #20040
Refs #19738
Refs #20039

## Validation Steps Performed

1. Korean IME: compose `ㄷ` between `가` and `나` → display shows `가ㄷ나`,
`나` visible.
2. TUI box (vim prompt with padding): compose inside padded text box →
border preserved in place.
3. Composition at end of line (no chars to right): unaffected.
4. English and other IME input: not affected (no active composition
row).

b2666fb346 Fix local tests (#20120)
## Summary of the Pull Request
Fixes TabTests.cpp. Changes include:
- add `"closeOnExit": "never"` to some tests to avoid the race condition
discussed in #14623. It keeps the tabs/panes around so that we can
actually test them.
- removes the `assert(false)` in `TermControl::MinimumSize()`. I've been
hitting this assert in dev builds _every time_ I split a pane. I think
it isn't adding value, but if we want to investigate it further, we can.
- update MRU tests to not use the command palette (aka tab switcher) UI.
The UI requires you to hold a modifier key down to keep it displayed.
That isn't something we can simulate. Instead we just use the relevant
APIs to simulate switching tabs. This is ok because the `MRU` list is
still updated, so we're still able to validate that we're updating it
properly.
- Add `Tab[idx]` and `MRU[idx]` notation to MRU tests to make them
easier to follow

8f4fdf9751 Normalize commandline in media resource tests (#20118)
## Summary of the Pull Request
Some of the Media Resource tests were failing on my machine. Turns out
that it's because my machine uses `C:\WINDOWS` instead of `C:\Windows`.

This PR fixes those tests by calling `Profile::NormalizeCommandline()`
on a few impacted strings. This also makes them loaded after enabling
filesystem redirection in `TEST_CLASS_SETUP` so that we resolve to the
correct path expected by x86.

Admittedly, I'm not the biggest fan of using that to fix the tests, but
it's better than the alternative which is a case-insensitive string
comparison. Also, the tests are testing fallback behavior, so this
doesn't really impact that. It just makes the tests more consistently
reliable.

This also removes the unused `pingCommandline` variable.

a6ebdd3d4a render: check the thread exit condition after every long operation (#20097)
We have received an internal report that teardown on OneCore is still
hanging. It looks like there's a chance that `TriggerTeardown` is called
during `PaintFrame`, which may result in `_threadShouldKeepRunning`
getting set to `false` (TriggerTeardown) and `_redraw` being set to
`false` as well (PaintFrame). The thread will wait forever on `_redraw`
to be signalled, which it never will, because `TriggerTeardown` is
waiting for the thread to exit.

That is:

```
Render Thread      | ConIoSrv Thread
------------------------------------
Check _enabled     |
Wait on _redraw    |
Check _keepRunning | TriggerTeardown
Paint              |   _keepRunning = false
                   |   _redraw = true
    _redraw = false|   Signal _enabled
Paint Completes    |   Wait on thread
Check _enabled     |
Wait on _redraw    |
**DEADLOCK**       | **DEADLOCK**
                   v
```

This may not be an ideal fix, but at least it checks
`_threadShouldKeepRunning` after every "long" operation (waiting and
painting) now.

81170aff78 Display a warning dialog for unsafe URLs (#20065)
We are getting a sufficient number of LLM-generated security reports
telling us that Ctrl+click and a tooltip are insufficient protection
from users clicking on links to dangerous things.

This commit displays a warning that prevents users from blindly clicking
on dangerous things.

Dangerous things include:
- any non-http and non-https and non-file URLs
- any file URLs that point to something understandable as a "program"
(so, something which resides in `PATHEXT`.)

In doing this, I learned that `til::ends_with_insensitive_ascii` was
broken.

I also learned that ContentDialogs summoned by any event handler out of
TermControl::Pointer* would lose focus immediately. It turns out that in
the absolute earliest days of Terminal, when we first created the
UserControl that became TermControl, we added our Tapped event handler.

It unconditionally focused the control.

Since `Tapped` is a higher-level event handler than `PointerPressed`, it
was firing after the gesture that opened the content dialog and stealing
focus back.

I'm fairly certain we don't need it.

WpfTerminalControl to depend on,) we're going to need to track these in
Interactivity too.

This also converts the arguments from the winrt-specific
Foundation::Point to Core::Point, and simplifies some of the signatures
to no longer pass things we do not need to pass.

Right now, this should result in no functional change.

Some of the tests are sensitive to the fact that we never loaded
`SPI_GETWHEELSCROLLLINES`
and instead defaulted to `1`. They've been hammered back into shape.

14f4271954 Fix Korean IME arrow key inserting character at wrong position (#20039)
Fix a regression introduced in v1.24 where pressing an arrow key during
Korean IME composition caused the committed character to be inserted at
the wrong cursor position.

Before #19738, the Korean IME activated through IMM32 (excluded from TSF
by `TF_TMAE_UIELEMENTENABLEDONLY`) and was not affected by
`TermControl::_KeyHandler` forwarding keys to the PTY during
composition. After #19738, the Korean IME activates through TSF, making
a missing composition guard in `_KeyHandler` visible as a bug.

The sequence of events that causes the bug:

1. User presses Left arrow during active Korean IME composition (e.g.
composing `가`).
2. `_KeyHandler` calls `_TrySendKeyEvent(VK_LEFT)` which enqueues
`\x1b[D` to the PTY input queue. The cursor moves.
3. TSF processes the key. The Korean IME sees the arrow and ends the
composition.
4. `OnEndComposition` schedules `_doCompositionUpdate` with
`TF_ES_ASYNC`.
5. The async session fires, reads finalized text `가`, calls
`HandleOutput("가")`.
6. PTY processes `[\x1b[D, "가"]`: cursor moves left first, then `가` is
inserted at the wrong (already-moved) position.

The fix adds a guard before `_TrySendKeyEvent`, which mirrors the
existing behavior in conhost (windowio.cpp). When TSF has an active
composition, key events are not converted into input. The Korean IME
re-injects navigation and confirmation keys after the composition ends,
at which point `HasActiveComposition()` returns false and they are
forwarded normally.

**Historical note:** This guard was not needed before PR #17067 (v1.22)
because the old implementation used WinRT `CoreTextServices` via XAML
(`TSFInputControl.xaml`). The XAML framework intercepted composition key
events before `_KeyHandler`. The new custom Win32 TSF context in #17067
no longer does this. The bug was latent from v1.22 but only became
visible for Korean in v1.24 when #19738 removed
`TF_TMAE_UIELEMENTENABLEDONLY`.

## Validation Steps Performed

1. Open Windows Terminal with Korean IME (Dubeolsik layout).
2. Type `rk` to begin composing `가` (composition active, syllable not
yet committed).
3. Press the Left arrow key.
4. Before fix: `가` is inserted one cell to the left of the intended
position.
5. After fix: `가` is inserted at the correct position, then cursor moves
left.

Also verified:
- Normal Korean text input (typing without arrow keys) still works
correctly.
- Arrow key navigation when no composition is active still works
correctly.
- English and other IME input is not affected.

2870a702f4 Reinstate the (apparently) load-bearing empty bracketed paste (#20037)
Some applications have come to rely on an "empty" bracketed paste packet
to indicate that the clipboard was _requested,_ but not sent. Some
agentic CLI tools use this to guess whether the clipboard contained e.g.
an image or otherwise unserializable data.

Apparently, gnome-terminal and VS Code do this; others as well (I tested
xterm, konsole, gnome-terminal and I can't remember which ones did and
which ones did not.)

ec939aabda Update 'restart connection' action to reset internal state (#19971)
## Summary of the Pull Request
I was becoming frustrated with getting in a state where a CLI app (i.e.
Copilot CLI) enters some VT state (like mouse mode) then doesn't unset
it when it accidentally exits. I normally use "Restart connection" to
keep the buffer and connect again. Problem is, "restart connection"
didn't actually reset the internal state! So I would type and get a
bunch of lingering VT escape sequences. This bug is tracked over in
#18425 in a more generic way.

This fixes that bug by doing the following:
- update `ITermDispatch::HardReset()` -->`HardReset(bool erase)`
   - `erase=true` does what `HardReset()` already did
- `erase=false` skips over clearing the screen and resetting the cursor
position
- expose `HardReset(false)` as `HardResetWithoutErase()` by piping it up
through `Terminal` --> `ControlCore` --> `TermControl`
-  update the restart connection handler
- `TerminalPage::_restartPaneConnection()` now calls
`HardResetWithoutErase()` before setting the new connection
- this is also the same route for the "Enter to restart connection"
scenario (text displayed when connection ends)

Relevant notes from PR discussion:
- `PSEUDOCONSOLE_INHERIT_CURSOR` is passed into the new connection via
`_restartPaneConnection()` --> `_duplicateConnectionForRestart()` -->
`_CreateConnectionFromSettings(profile,
*controlSettings.DefaultSettings(), true)`

## Validation Steps Performed
- Used this to enter mouse tracking mode: `Write-Host -NoNewline
"`e[?1003h`e[?1006h"`
- mouse selection doesn't work as usual (expected)
- invoke "restart connection" action
- mouse selection works as usual

be5dcf8e7a Fix MSB4019 error in ConPTY nupkg (#20029)
This commit fixes the following error that occurs when attempting to use the
`Microsoft.Windows.Console.ConPTY` nupkg in a Visual C++ project:

    MSB4019: The imported project "C:\Microsoft.Windows.Console.ConPTY.props" was not found.

Based on the list of reserved and well-known properties, the property
`MSBuildThisProjectDirectory` does not appear to exist.  This PR
replaces it with the correct property, `MSBuildThisFileDirectory`.

4ce79d7289 Implement OSC 7 for setting the CWD (#20019)
This adds support for OSC 7 which is the same as OSC 9;9 but using
file URIs. As per the previous discussion in #8214, the problem is
that WSL shells emit URIs that can't work because the hostname in
the URI translates to an UNC path with an non-existing hostname.
In my opinion this doesn't deter the fact though that OSC 7 works
just fine for a native Windows application.

In the future we should consider trying to detect WSL file URIs
and translating it to the `--cd` argument for `wsl.exe`.

All of the heavy lifting for parsing the URI is done by 
`PathCreateFromUrlW`. It just had to be plugged into the OSC 9;9 code.

Closes #3158

## Validation Steps Performed
* Launch fish-shell in WSL
* Duplicate tab works 
* (And because it doesn't work without using
  `IsValidDirectory` I know that OSC 7 works )

69e4590bc5 Add setting for customizable delimiter for file drag-and-drop (#19799)
## Summary of the Pull Request
This PR introduces a new profile setting, `dragDropDelimiter`, which
allows users to configure the string separator used when dragging and
dropping multiple files into the terminal. The default behavior remains
a single space (`" "`) for backward compatibility.

## References and Relevant Issues
* Closes #19565

## Detailed Description of the Pull Request / Additional comments
**Implementation Details:**
* **Settings:** Added `DragDropDelimiter` to `MTSMSettings.h` and
`Profile.idl`.
* **Control:** Wired the setting through `ControlProperties.h` so the
terminal logic can see it.
* **Logic:** Updated `TermControl::OnDrop` to use the new delimiter when
joining paths.
* **UI:** Added the text box in the Advanced Settings page and updated
the ViewModel.

## Validation Steps Performed
* **Manual Verification:**
    * Verified default behavior (space separator) works as before.
* Configured `dragDropDelimiter` to `", "`, `";"`, and custom strings in
`settings.json` and from settings UI.
    * Confirmed dropped files are joined correctly.
* **Build:** Validated that the solution builds cleanly.

## Notes for Reviewers
1. **Delimiter Length:** Currently, there is no limit on the maximum
length of the delimiter string. Let me know if this should be changed.
3.  **Localization:** I changed only `Resources/en-US` file.
4. **ViewModel:** In `ProfileViewModel.cpp`, I added the `else if` block
for the new setting, but left it empty because no other UI logic
currently depends on it.

## PR Checklist
- [x] Closes #19565
- [ ] Documentation updated
- [x] Schema updated (if necessary)
