Right now, we do not use a sufficiently unique name to disambiguate
Terminal instances running on the same desktop.
Mutexes (mutants) are named objects that live in the user's session,
under `Sessions\1\BaseNamedObjects` (for the local desktop session).
When multiple users are logged into the same session--such as with "Run
as different user"--they share a local BaseNamedObjects namespace. Ugh.
We cannot use [`CreatePrivateNamespace`] as it requires a boundary
descriptor, and the only boundary descriptors supported by the current
API are based on package identity. I also fear that
`CreatePrivateNamespace` is subject to a race condition with
`OpenPrivateNamespace`; Create will not Open an existing one, so we
would need to back off and retry either opening or creating. Yuck.
After this commit, we will hash the user's SID into the name of both the
window class and the mutant, right after the path hash (if running
unpackaged).
Closes#18704

The crash occurs because WinRT `abort()`s when it encounters
a `std::wstring_view` without null-terminator.

## Validation Steps Performed
* Set `wtd` as the default terminal
* Launch `cmd`
* Launch `wtd`

When we first transitioned to the `R1` network isolation
environment--which required us to _not_ contact
powershellgallery.com--we had to give up on the `AzureFileCopy` task.
Since then, the `AzurePowerShell` task has also become somewhat broken
while OneBranch fixed the issue that prevented us from using
`AzureFileCopy`.
In short, we now need to:
- Install the Azure PowerShell modules directly from our own feed (which
satisfies the network constraint)
- ... using `PSResourceGet` ...
- ... for Windows PowerShell 5.1 ...
- which is used by `AzureFileCopy` to later perform authentication.
This changes the ConPTY handoff COM server from `REGCLS_SINGLEUSE`
to `REGCLS_MULTIPLEUSE`. The former causes a race condition, because
handoff runs concurrently with the creation of WinUI windows.
This can then result in the a window getting the wrong handoff.
It then moves the "root" of ConPTY handoff from `TerminalPage`
(WindowEmperor -> AppHost -> TerminalWindow -> TerminalPage)
into `WindowEmperor` (WindowEmperor).
Closes#19049
## Validation Steps Performed
* Launching cmd from the Start Menu shows a "Command Prompt" tab ✅
* Win+R -> `cmd` creates windows in the foreground ✅
* Win+R -> `cmd /c start /max cmd` creates a fullscreen tab ✅
* This even works for multiple windows, unlike with Canary ✅
* Win+R -> `cmd /c start /min cmd` does not work ❌
* It also doesn't work in Canary, so it's not a bug in this PR ✅
Introduces an ABI change to the ConptyClearPseudoConsole signal.
Otherwise, we have to make it so that the API call always retains

Closes#18732Closes#18878
## Validation Steps Performed
* Launch `ConsoleMonitor.exe`
* Create some text above & below the cursor in PowerShell
* Clear Buffer
* Buffer is cleared except for the cursor row ✅

Fixes a crash when multiple panes were closed simultaneously (i.e. using
broadcast input).
The root cause of this crash was that we would get a null pointer
exception when trying to access a member/function off of a null
`_content`. This is because `Pane::_CloseChild()` would always pass over
the content from the non-closed pane and attempt to hook everything up
to it.
The fix was to operate similarly to `Pane::Close()` and raise a `Closed`
event and return early. Since there's no alternative content to attach
to, might as well just close the entire pane. This propagates up the
stack of listeners to update the UI appropriately and close the parent
pane and eventually the entire tab, if necessary.
Closes#18071Closes#17432
## Validation Steps Performed
1. Open 2 panes
2. Use broadcast input to send "exit" to both panes
3. ✅ Terminal doesn't crash and the tab closes gracefully

Adds logic to display a warning popup if the settings.json is marked as
read-only and we try to write to the settings.json file. Previously,
this scenario would crash, which definitely isn't right. However, a
simple fix of "not-crashing" wouldn't feel right either.
This leverages the existing infrastructure to display a warning dialog
when we failed to write to the settings file. The main annoyance here is
that that popup dialog is located in `TerminalWindow` and is normally
triggered from a failed `SettingsLoadEventArgs`. To get around this,
`CascadiaSettings::WriteSettingsToDisk()` now returns a boolean to
signal if the write was successful; whereas if it fails, a warning is
added to the settings object. If we fail to write to disk, the function
will return false and we'll raise an event with the settings' warnings
to `TerminalPage` which passes it along to `TerminalWindow`.
Additionally, this uses `IVectorView<SettingsLoadWarnings>` as opposed
to `IVector<SettingsLoadWarnings>` throughout the relevant code. It's
more correct as the list of warnings shouldn't be mutable and the
warnings from the `CascadiaSettings` object are retrieved in that
format.
## Validation Steps Performed
- ✅ Using SUI, save settings when the settings.json is set to read-only
Closes#18913
sgr_n previously used a mutable list (`seq=[]`) as its default parameter.
In Python, default arguments are instantiated once at
function‐definition time and then shared across all calls.
If any caller mutated that list (e.g., `seq.append(...)`), later
invocations would inherit the mutated state, producing unpredictable or
corrupted VT-test sequences.
## Summary of the Pull Request
Some applications that make use of the `OSC 52` clipboard sequence will
only do so if they can be certain that the terminal actually has that
functionality. Indicating our support for `OSC 52` in the `DA1` report
will give them an easy way to detect that.
## References and Relevant Issues
`OSC 52` support was added to Windows Terminal in issue #5823, and to
ConHost in issue #18949.
## Detailed Description of the Pull Request / Additional comments
Support for writing to the clipboard is indicated in the primary device
attributes report by the extension parameter `52`. This is obviously not
a standard DEC extension, but it's one that's been agreed upon by a
number of modern terminals. The extension is only reported when writing
to the clipboard is actually permitted (Windows Terminal has an option
to disable that).
## Validation Steps Performed
I've updated the Device Attributes unit test to check that we're
reporting extension `52` when clipboard access is enabled, and not
reporting it when disabled.

Right now, image validation accepts web-sourced icons (boo) and rejects
images whose paths begin with `\\?\`. In addition, it will warn the user
for things out of their control like images set by fragments.
This pull request adds a filesystem path validator (which accepts images
with fully-qualified paths and UNC paths), makes the URI validator
reject any web-origin URIs (only `file` and `ms-*` are allowable), and
suppresses warnings for any images that were not _directly_ set by the
user.
Since we want to avoid using fragment images that fail validation, we no
longer `Clear` each image property but rather set it to the blank or
fallback value.
This does **not** actually add support for images at absolute paths
beginning with `\\?\`. Such images are still rejected by `Image` and the
other XAML fixtures we use for images. It's better than a warning,
though.

If High Contrast mode is enabled in the OS settings, we now
automatically enable `adjustIndistinguishableColors`. To accomplish
this, a new `Automatic` value is added to
`adjustIndistinguishableColors`. When it's chosen, color nudging doesn't
occur in regular contrast sessions, but we interpret the value as
`Indexed` respectively.
The new default value is `AutomaticIndexed`. Meaning that regular
contrast sessions will see no difference in behavior. However, if they
switch to high contrast mode, Windows Terminal will interpret the value
as `Indexed` at runtime. This was chosen because `Always` is more
performance intensive.
## References and Relevant Issues
#12999
## Validation Steps Performed
✅ Toggling High Contrast mode immediately triggers an updated terminal
instance with `adjustIndistinguishableColors`
Prevents a crash when no storage items are returned from a dropped path.
Terminal no longer crashes when a relative path is dragged and dropped
into the tool.

With the latest winget-create release, the preferred method for
providing the GitHub token in CI/CD environment is via the environment
variable `WINGET_CREATE_GITHUB_TOKEN`. Removed use of `--token` and
switched to environment variable. See https://aka.ms/winget-create-token
for details.
This is an attempt to improve the correctness of the background fill
that the Sixel parser performs when an image is scrolled because it
doesn't fit on the screen.
This new behavior may not be exactly correct, but does at least match
the VT330 and VT340 hardware more closely than it did before.
The initial Sixel parser implementation was in PR #17421.
When a Sixel image has the background select parameter set to 0 or 2, it
fills the background up to the active raster attribute dimensions prior
to writing out any actual pixel data. But this fill operation is clamped
at the boundaries of the screen, so if the image doesn't fit, and needs
to scroll, we have to perform an additional fill at that point to cover
the background of the newly revealed rows (this is something we weren't
doing before).
This later fill uses the width of the most recent raster attributes
command, which is not necessarily the same as the initial background
fill, and fills the entire height of the new rows, regardless of the
height specified in the raster attributes command.
## Validation Steps Performed
Thanks to @al20878 and @hackerb9, we've been able to test on both a
VT330 and a VT340, and I've confirmed that we're matching the behavior
of those terminals as closely as possible. There are some edge cases
where they don't agree with each other, so we can't always match both.
I've also confirmed that the test case in issue #17946 now matches what
the OP was expecting, and the test case in #17887 at least works more
consistently now when scrolling (this is not what the OP was expecting
though).
Closes#17887Closes#17946
This adds support for copying to the clipboard in conhost using the OSC
52 escape sequence, extending the original implementation which was for
Windows Terminal only.
The Windows Terminal implementation was added in PR #5823.
Because the clipboard can't be accessed from a background thread, this
works by saving the content in a global variable, and then posting a
custom message to the main GUI thread, which takes care of the actual
copy operation.
Validation:
I've manually confirmed that tmux copy mode is now able to copy to the
system clipboard.
Closes#18943
Some minor styling tweaks to the about page.
- Tweaking the spacing of the version-checking / update available text.
- Wrapping the hyperlinkbuttons in a StackPanel so it's easier to set a
negative margin so they are visually aligned with the version / title
text.
Closes#18994
It's the fzf algorithm!
Repurposed work from #16586
- I think the fzf algo fits here where it optimizes to find the optimal
match based on consecutive chars and word boundaries.
- There are some edge cases where a match with a small gap could get a
higher score than a match of consecutive chars when the match with a
gap has other bonuses (FirstChar * Boundary Bonus). This can be
adjusted by adjusting the bonuses or removing them if needed.
- From reading the thread in #6693 it looked like you guys were leaning
towards something like the fzf algo.
- License file is now updated in
https://github.com/nvim-telescope/telescope-fzf-native.nvim repository
- https://github.com/nvim-telescope/telescope-fzf-native.nvim/pull/148
- https://github.com/junegunn/fzf/issues/4310
- Removed the following from the original implementation to minimize
complexity and the size of the PR. (Let me know if any of these should
be added back).
- Query expressions "$:StartsWith ^:EndsWith |:Or !:Not etc"
- Slab to avoid allocating the scoring matrix. This felt like overkill
for the number of items in the command pallete.
- Fallback to V1 algorithm for very long strings. I want to say that the
command palette won't have strings this long.
- Added the logic from GH#9941 that copies pattern and text chars to
string for comparision with lstrcmpi
- It does this twice now which isn't great...
Closes#6693
