The `_CONSOLE_API_MSG` buffer is resized to cover an entire message.
Later on any UTF-8 data is cached in a separate temporary
buffer inside `til::u8state` to prevent lone surrogate pairs.
Both cases are problematic as neither buffer is freed after the read
has finished. Passing a 100MB buffer to conhost once will thus cause it
to continue using ~220MB of physical memory until the conhost process exits.
This change releases unneeded memory as soon as the requested buffer
size has halved. In practice this means that once a command has returned
all buffers will shrink, as the shell commonly sends very small messages.

Change accessibility notifier creation so we do not create one when we're in PTY mode. (Guard all call sites to skip math/event work when the notifier is null.) MSAA events are legacy events that are registered for globally and used by some screen readers to find content in the conhost window. The PTY mode is not responsible for hosting the display content or input window, so it makes sense for it to not broadcast these events and delegate the accessibility requirement to the connected terminal.

## Detailed Description of the Pull Request / Additional comments
It turns out that there's a bit of ownership that goes on with the original inbox `conhost.exe` and the operating system/driver. The PID of that original `conhost.exe` is stowed when the initial connection is established and it is verified for several activities. This means that the plan of letting it go completely away and having the `OpenConsole.exe` take over all of its activities must be slightly revised.
I have tested the following two alternatives to keeping `conhost.exe` around and they do not work:
1. Replacing the original owner `conhost.exe` with `OpenConsole.exe` - A.) The driver does not allow this. Once the owner is registered, it cannot be replaced. B.) There's no way of updating this information inside the client process space and it is kept there too in the `kernelbase`/`conclnt` data from its initial connection.
2. Attempting to pick up the first packet (to determine headed/headless and other initial connection information that we use to determine whether handoff is appropriate or not) prior to registering any owner at all. - The driver doesn't allow this either. The owner must be registered prior to a packet coming through.
Put this mental model in your head:
CMD --> Conhost (inbox) --> OpenConsole (WT Package) --> Terminal (WT Package)
So since the `conhost.exe` needs to stick around, here's what I'm doing in this PR:
- `conhost.exe` in the OS will receive back the `OpenConsole.exe` process handle on a successful handoff and is expected to remain alive until the `OpenConsole.exe` exits. It's now waiting on that before it terminates itself.
- `conhost.exe` in the OS will establish a signal channel pipe and listen for control commands from `OpenConsole.exe` in a very similar fashion to how the `ConPTY` signal pipe operates between the Terminal and the PTY (provided by `OpenConsole.exe` in this particular example.) When `OpenConsole.exe` needs to do something that would be verified by the OS and rejected... it will instead signal the original `conhost.exe` to do that thing and it will go through.
- `conhost.exe` will give its own handle through to `OpenConsole.exe` so it can monitor its lifetime and cleanup. If the owner is gone, the session should end.
- Assorted handle cleanup that was leading to improper exits. I was confused between `.reset()` and `.release()` for some of the `wil::unique_any<T>` handling and it lead to leaked handles. The leaked handles meant that threads weren't aware of the other sides collapsing and wouldn't cleanup/terminate appropriately.
How does this fix things?
- For the WSL cases... WSL was specifically looking up the owner PID of the console session from the driver. That was the `conhost.exe` PID. If it exits, that PID isn't valid and is recycled. Thus the parameter is incorrect or other inappropriate WSL setup behaviors.
- Ctrl+C not passed... this is a signal the operating system rejects from a PID that is not the owner. This is now relayed through the original owner and it works.
- Leftover processes... I believe I explained this was both not-enough-monitoring of each others' process lifetimes coupled with mishandling of release/resetting handles and leaking them.
- Powershell sometimes fails to attach... my theory on this one is that it's a race that became upset when the `conhost.exe` disappeared while something about Powershell/.NET was still starting, much like the WSL one. I believe now that it is sticking around, it will be fine.
Also, this WILL require an OS update to complete improvement of functionality and I have revised the interface ID. This is considered an acceptable breaking change with no mitigation because we said this feature was an alpha preview.
## Validation Steps Performed
- Launched WSL with defapp set, it works
- Launched WSL with defapp set and the debug tap on, it works and opens in two tabs
- Launched CMD, ran ping, did Ctrl+C, it now receives it
- Launched Win+X powershell a ton of times. It seems fine now
- Launched cmd, powershell, wsl, etc. Killed assorted processes in the chain (client/conhost/openconsole/windowsterminal) and observed in Process Explorer (with a long delta timer so I could see it) that they all successfully tear down now without leftovers.
## Summary of the Pull Request
This commit introduces a copy constructor/operator for
`_CONSOLE_API_MSG`. The change is not trivial as the struct contains a
union of unnamed structs that cannot be copied using regular language
features. As such a copy operator using `memcpy` was implemented.
Additionally all access specifiers were removed, as those allow a C++
compiler to reorder struct members. This would break message passing.
This commit is a good opportunity to prevent such miscompilations
proactively.
## Validation Steps Performed
* Command prompts of WSL2 fish-shell and pwsh still work ✔️Closes#10076
This pull request converts four of our existing `#ifdef` (or `#ifndef`)
`INSIDE_WINDOWS` blocks to til::features:
* Attempting to establish a handoff session (inside Windows only)
* The ability to *receive* a handoff session (outside Windows only)
* The DX engine (outside Windows only) and shaders (also outside only)
* Whether we use numpad event synthesis for clipboard/conpty (inside
Windows only)
Most of these are using the preprocessor verison of til::feature, only
because it is more difficult to gate the inclusion of headers on
constant expressions. I'd love to prefer the compile time version.
Set keyword flags on all events so those sharing a provider with

## PR Checklist
* [x] Closes#10093
* [x] I work here
* [x] Tests passed
* [x] Documentation added in `til.h` about how keywords work and at the
only other site of keywords we define in the Host project tracing

## Detailed Description of the Pull Request / Additional comments
I initially thought that we would need to split providers here to
accomplish this... but @DHowett helped me realize that might be a lot of
additional metadata and bloat binary size. So with help from a friend
from fundamentals, I realized that we could use Keywords to
differentiate here. We can no longer define 0 keywords as that
represents an any/all scenario. Every `TraceLoggingWrite` event now
needs a keyword. When our events have a keyword, they're not included in
any trace. Additionally, when we have an explicit keyword to check that
is different from the ones used for the telemetry pipeline, we can
ensure that we only do "hard work" to generate debug trace data when an
"ALL" type listener like TraceView or Windows Performance Recorder with
our profiles is listening to these providers for ALL keyworded events.
## Validation Steps Performed
- [x] - Built with full release build config to confirm performance is
worse than dev builds BECAUSE of the telemetry event collector camping
our provider and triggering full trace event generation on shared
providers.
- [x] - Built with full release build config to enable statistics
collection and validated trace event collection is excluded and trace
event short-circuits work with this change.
- [x] - Checked that TraceView still sees both telemetry and tracing
events
- [x] - Checked that WPR with our .wprp profile sees both telemetry and
tracing events
Until there's a "Wait", there's usually only one API message inflight at
a time.
In our quest for performance, we put that single API message in charge
of its own buffer management: instead of allocating buffers on the heap
and deleting them later (storing pointers to them at the far corners of
the earth), it would instead allocate them from small internal pools (if
possible) and only heap allocate (transparently) if necessary. The
pointers flung to the corners of the earth would be pointers (1) back
into the API_MSG or (2) to a heap block owned by boost::small_vector.
It took us months to realize that those bare pointers were being held by
COOKED_READ and RAW_READ and not actually being updated when the API
message was _copied_ as it was shuffled off to the background to become
a "Wait" message.
It turns out that it's trivially possible to crash the console by
sending two API calls--one that waits and one that completes
immediately--when the waiting message or the "wait completer" has a
bunch of dangling pointers in it. It further turns out that some
accessibility software (like JAWS) attaches directly to the console
session, much like winpty and ConEmu and friends. They're trying to read
out the buffer (API call!) and sometimes there's a shell waiting for
input (API call!). Oops.
In this commit, we fix up the message's internal pointers (in lieu of
giving it a proper copy constructor; see GH-10076) and then tell the
wait completion routine (which is going to be a COOKED_READ, RAW_READ,
DirectRead or WriteData) about the new buffer location.
This is a scoped fix that should be replaced (TODO GH-10076) with a
final one after Ask mode.

This commit fixes two issues:
1. We were pushing ConsoleWaitBlocks into the wait queue before they
were fully constructed. This resulted in the wait being called before
it even had an API message in it. [MSFT-24113101]
2. Drawing DBCS characters and resizing (a lot) would cause a crash
because of an invalid DBCS cell state. This hits in both Terminal and
conhost. [MSFT-17364373] [GH-4907]
The DBCS state check was promoted from an NT_ASSERT (which never fired
in release) to a FAIL_FAST in !1794053. The console kept chugging along
without failing in fre for all those years.

## Detailed Description of the Pull Request / Additional comments
Transient allocations are those that are new'd, used, then delete'd. Going back and forth to the system allocator for things we're just going to throw away or use rapidly again is a performance detriment. Not only is it a bunch of time to go ask the system with a syscall, it also hits a whole bunch of locks on the allocators. This PR identifies a few places where we were accidentally allocating and didn't mean to or were allocating and freeing just to turn around and allocate again. I chose other strategies to avoid this.
## Validation Steps Performed
- Ran `big.txt` sample (~6MB file) before and after. Observed heap allocations with WPR.
This commit replaces DeviceComm with the interface IDeviceComm and the
concrete implementation type ConDrvDeviceComm. This work is done in
preparation for different device backends.
In addition to separating out ConDrv-specific behavior, I've introduced
a "handle exchange" interface.
HANDLE EXCHANGE
---------------
There are points where we give ConDrv opaque handle identifiers to our
input buffer, output buffer and process data. The exact content of the
opaque identifier is meaningless to ConDrv: the driver's only
interaction with these identifiers is to hold onto them and send back
whichever are pertinent for each API call.
Because of that, we used the raw register-width pointer value of the
input buffer, output buffer or process data _as_ the opaque handle
value.
This works very well for ConDrv <-> conhost using the ConDrvDeviceComm.
It works less well for something like the "logging" DeviceComm that will
log packets to a file: those packets *cannot* contain pointer values (!)
To address this, and to afford flexibility to DeviceComm implementers,
I've introduced a two-member complement of handle management functions:
* `ULONG_PTR PutHandle(void*)` registers an object with the DeviceComm
and returns an opaque identifier.
* `void* GetHandle(ULONG_PTR)` takes an opaque identifier and returns
the original object.
ConDrvDeviceComm implements PutHandle and GetHandle by casting the
object pointer to the "opaque handle value", which maintains wire format
compatibility[1] with revisions of conhost prior to this change.
Simpler DeviceComm implementations that require handle tracking but
cannot bear raw pointers can implement these functions by returning an
autoincrementing ID (or similar) and registering the raw object pointer
in a mapping.
I've audited all existing handle exchanges with the driver and updated
them to use Put/GetHandle.
(I intended to add DestroyHandle, but we are not equipped for handle
removal at the moment. ConsoleHandleData/ConsoleProcessHandle are
destroyed during wait routine completion, on client disconnect, etc.
This does mean that an id<->pointer mapping will grow without bound, but
at a cost of ~8 bytes per entry and a short-lived console session I am
not too concerned about the cost.)
[1] Wire format compatibility is not required, and later we may want to
switch ConDrvDeviceComm to `EncodePointer` and `DecodePointer` just to
insulate us against a spurious ConDrv packet allowing for an arbitrary
4/8-byte read and subsequent liftoff into space.
Many include statements use forward slashes, while others use backwards
slashes. This is inconsistent formatting. For this reason, I changed the
backward slashes to forward slashes since that is the standard.
We were using std::basic_string_view as a stand-in for std::span so that
we could change over all at once when C++20 dropped with full span
support. That day's not here yet, but as of 54a7fce3e we're using GSL 3,
whose span is C++20-compliant.
This commit replaces every instance of basic_string_view that was not
referring to an actual string with a span of the appropriate type.
I moved the `const` qualifier into span's `T` because while
`basic_string_view.at()` returns `const T&`, `span.at()` returns `T&`
(without the const). I wanted to maintain the invariant that members of
the span were immutable.
* Mechanical Changes
* `sv.at(x)` -> `gsl::at(sp, x)`
* `sv.c{begin,end}` -> `sp.{begin,end}` (span's iterators are const)
I had to replace a `std::basic_string<>` with a `std::vector<>` in
ConImeInfo, and I chose to replace a manual array walk in
ScreenInfoUiaProviderBase with a ranged-for. Please review those
specifically.
This will almost certainly cause a code size regression in Windows
because I'm blowing out all the PGO counts. Whoops.
Related: #3956, #975.
There is going to be a very long tail of applications that will
explicitly request VT SGR 40/37 when what they really want is to
SetConsoleTextAttribute() with a black background/white foreground.
Instead of making those applications look bad (and therefore making us
look bad, because we're releasing this as an update to something that
"looks good" already), we're introducing this compatibility quirk.
Before the color reckoning in #6698 + #6506, *every* color was subject
to being spontaneously and erroneously turned into the default color.
Now, only the 16-color palette value that matches the active console
background/foreground color will be destroyed, and only when received
from specific applications.
Removal will be tracked by #6807.
Michael and I discussed what layer this quirk really belonged in. I
originally believed it would be sufficient to detect a background color
that matched the legacy default background, but @j4james provided an
example of where that wouldn't work out (powershell setting the
foreground color to white/gray). In addition, it was too heavyhanded: it
re-broke black backgrounds for every application.
Michael thought that it should live in the server, as a small VT parser
that righted the wrongs coming directly out of the application. On
further investigation, however, I realized that we'd need to push more
information up into the server (so that it could make the decision about
which VT was wrong and which was right) than should be strictly
necessary.
The host knows which colors are right and wrong, and it gets final say
in what ends up in the buffer.
Because of that, I chose to push the quirk state down through
WriteConsole to DoWriteConsole and toggle state on the
SCREEN_INFORMATION that indicates whether the colors coming out of the
application are to be distrusted. This quirk _only applies to pwsh.exe
and powershell.exe._
NOTE: This doesn't work for PowerShell the .NET Global tool, because it
is run as an assembly through dotnet.exe. I have no opinion on how to
fix this, or whether it is worth fixing.
VALIDATION
----------
I configured my terminals to have an incredibly garish color scheme to
show exactly what's going to happen as a result of this. The _default
terminal background_ is purple or red, and the foreground green. I've
printed out a heap of test colors to see how black interacts with them.
Pull request #6810 contains the images generated from this test.
The only color lines that change are the ones where black as a
background or white as a foreground is selected out of the 16-color
palette explicitly. Reverse video still works fine (because black is in
the foreground!), and it's even possible to represent "black on default"
and reverse it into "default on black", despite the black in question
having been `40`.
Fixes#6767.
## Summary of the Pull Request
This PR implements a pair of shims for `cmd` and `powershell`, so that their `cls` and `Clear-Host` functions will clear the entire terminal buffer (like they do in conhost), instead of just the viewport. With the conpty viewport and buffer being the same size, there's effectively no way to know if an application is calling these API's in this way with the intention of clearing the buffer or the viewport. We absolutely have to guess.
Each of these shims checks to see if the way that the API is being called exactly matches the way `cmd` or `powershell` would call these APIs. If it does, we manually write a `^[[3J` to the connected terminal, to get he Terminal to clear it's own scrollback.
~~_⚠️ If another application were trying to clear the **viewport** with an exactly similar API call, this would also cause the terminal scrollback to get cleared ⚠️_~~
* [x] Should these shims be restricted to when the process that's calling them is actually `cmd.exe` or `powershell.exe`? Can I even do this? I think we've done such a good job of isolating the client process information from the rest of the host code that I can't figure out how to do this.
- YES, this can be done, and I did it.
* [ ] **TODO**: _While I'm here_, should I have `DoSrvPrivateEraseAll` (the implementation for `^[[2J`, in `getset.cpp`) also manually trigger a EraseAll in the terminal in conpty mode?

This commit cleans up and deduplicates all of the common build
preamble/postamble across exe, dll, lib and c++/winrt projects.
The following specific changes have been made:
* All projects now define their ConfigurationType
* All projects now set all their properties *before* including a common
build file (or any other build files)
* cppwinrt.pre and cppwinrt.post now delegate most of their
configuration to common.pre and common.post
* (becuase of the above,) all build options are conserved between
console and c++/winrt components, including specific warnings and
preprocessor definitions.
* More properties that are configurable per-project are now
conditioned so the common props don't override them.
* The exe, dll, exe.or.dll, and lib postincludes have been merged into
pre or post and switched based on condition as required
* Shared items (-shared, -common) are now explicitly vcxitems instead of
vcxproj files.
* The link line is now manipulated after Microsoft.Cpp sets it, so the
libraries we specify "win". All console things link first against
onecore_apiset.lib.
* Fix all compilation errors caused by build unification
* Move CascadiaPackage's resources into a separate item file
Fixes#922.
* Ensure rights check and increments pass before assigning an object to a handle (since deallocation of handles will automatically attempt to cleanup).
Adjusts the startup and shutdown behavior of most threads in the console host to alleviate race conditions that are either exacerbated or introduced by the VT PTY threads.
### User Stories:
1. A user wants to be able to use the executable path as their starting title
- Does anyone want this?
2. A user wants to be able to set a custom starting title, but have that title be overridable
3. A user wants to be able to set an overridable starting title, different from the profile name
- Presumably someone will want this
4. A user totally wants to ignore the VT title and use something else
- This will make more sense in the post [#1320] "Support runtime variables in the custom user title" settings
### Solutions:
1. `name`, `startingTitle`, `tabTitle`
* a. `name` is only ever used as the profile name.
* b. If `startingTitle` isn't set, then the executable path is used
* c. If `startingTitle` is set, it's used as the initial title
* d. If `tabTitle` is set, it overrides the title from the terminal
* e. Current users of `tabTitle` need to manually update to the new behavior.
2. `name` as starting title, `tabTitle` as a different starting title
* a. `name` is used as the starting title and the profile name in the dropdown
* b. If `tabTitle` is set, we'll use that as the overridable starting title instead.
* c. In the future, `dynamicTabTitle` or `tabTitleOverride` could be added to support [#1320]
* d. Current users of `tabTitle` automatically get the new (different!) behavior.
* e. User Story 1 is impossible
- Does anyone want the behavior _ever_? Perhaps making that scenario impossible is good?
3. `name` unchanged, `tabTitle` as the starting title
* a. `name` is only ever used as the profile name.
* b. If `tabTitle` is set, we'll use that as the overridable starting title.
* c. In the future, `dynamicTabTitle` or `tabTitleOverride` could be added to support [#1320]
* d. Current users of `tabTitle` automatically get the new (different!) behavior.
4. `name` as starting title, `tabTitle` as different starting title, `suppressApplicationTitle` Boolean to force it to override
* a. `name`, `tabTitle` work as in Solution 2.
* b. When someone wants to be able to statically totally override that title (story 4), they can use `suppressApplicationTitle`
* c. `suppressApplicationTitle` name is WIP
* d. We'll add `suppressApplicationTitle` when someone complains
* e. If you really want story 1, use `tabTitle: c:\path\to\foo.exe` and `suppressApplicationTitle`.
[#1320]: https://github.com/microsoft/terminal/issues/1320
