The root cause is that `OutputBuffer` is not cleaned up (set to `null`) in `Stop` and `BeginStop/EndStop` when the powershell instance owns the `OutputBuffer` object. Since the pipeline has been intentionally stopped by the caller, the `OutputBuffer` should be set to `null` as well when it's owned by the PowerShell instance, just like how it's cleaned up in `EndInvoke`.
- Adds y suffix that is used to specify a numeric literal as the sbyte data type.
- Can be combined with the existing u suffix as uy to specify the byte data type.
Replace code like BoundParameters.ContainsKey("Delimiter") with BoundParameters.ContainsKey(nameof(Delimiter)). Old pattern come from old C# (<6.0) without nameof().
The type System.IntPtr has an explicit cast operator defined that takes a pointer type System.void* parameter. Now we handle that type properly in GetPSMethodProjectedType.
Fixes#7230.
Adding the concept of a PSSyntheticTypeName, derived from PSTypeName,
that extends it with a list of synthetic members.
This allows us to express the inferred type of
```
[pscustomobject] @{
A = 1
B = "2"
}
```
as a "PSObject#A:B" and with information about the types of A and B.
This is also used to annotate the output of
```
Select-Object -Property
Select-Object -ExcludeProperty
Select-Object -ExpandProperty
```
Finally, it adds information about the types of the
`Group` and `Value` properties of the output of `Group-Object`
'cd +' adds the ability to revert 'cd -' by having another bounded stack with the same limit for 'redo' actions.
Behaviour is similar to back/forward navigation in explorer.exe
When the location is set to a path and the redo stack is non-empty then the redo stack gets flushed.
When cd + happens, then the redo stack is pushed to as well for a more intuitive way of navigating backwards and forwards.
All the work is done of course on the Set-location cmdlet, which is aliased to cd on all platforms.
Support calling methods with ByRef-like type parameters in PowerShell, as long as the argument specified for the parameter can be implicitly/explicitly converted to the ByRef-like type.
We cannot create an instance of a ByRef-like type in PowerShell, but there are types that can be implicitly or explicitly converted to ByRef-like types, such as `T[] -> Span<T>`, `T[] -> ReadOnlySpan<T>`, `String -> ReadOnlySpan<T>`. `ArraySegment<T> -> Span<T>`, `ArraySegment<T> -> ReadOnlySpan<T>`. With changes in this PR, we can call methods with ByRef-like parameter types by providing the arguments of the types that can be cast to the target ByRef-like type.
**What is enabled?**
1. Invoking methods that have ByRef-like parameters, but the return type is not ByRef-like.
2. Invoking constructors with ByRef-like parameters via `[target-type]::new` syntax, but the `target-type` is not ByRef-like.
3. Accessing indexers that have ByRef-like parameters, but the return type is not ByRef-like.
This change updates ModuleIntrinsics.GetModulePath to handle the case where the Windows PowerShell module path is already in the environment's PSModulePath or when launched from a different version of PowerShell.
Previously, GetModulePath would append $PSHOME\Modules to the PSModulePath after removing the path for the launching version without considering the Windows PowerShell module path. The result, was the Windows PowerShell modules were found first and loaded incompatible modules; such as the built-in modules.
The change detects the Windows PowerShell module path and inserts $PSHOME\Modules path before it. The new test simulates launching from a different version of pwsh that has already added the Windows PowerShell module path.
Fixes#7679
This change enables index operations on objects that implement `ITuple` and other interfaces that have `DefaultMemberAttribute` declared, including slicing and negative indexing.
* Remove regions in HistoryInfo class
* Auto properties refactoring in HistoryInfo
* Adding Duration property to HistoryInfo
* Rename ExecutionTime => Duration
ByRef-like types are supposed to be used on stack only, so we need to fail gracefully when accessing properties, calling methods, or creating objects related to ByRef-like types.
Default to DefaultConsoleWidth when DotNet says WindowWidth is 0
This resolves an issue in an environment like VSTS when pwsh is spawned and DotNet is not able to determine the Console Width.

Fix#7089. Native globbing on UNIX was turning absolute paths into relative paths when it shouldn't. The code suppresses generating a relative path for paths starting with '~'. It also need to do the same for paths starting with '/'.
`PSMemberInfoInternalCollection<T>` uses OrderedDictionary class internally. `OrderedDictionary` in dotnet core 2.1 allocates `ArrayList` and `Hashtable` after any first using any property. Even if the `OrderedDictionary` object is actually empty.
The commit postpones the internal allocations until it's really necessary. Given that `PSMemberInfoInternalCollection<T>` is used in each PSObject and is often empty, this change dramatically reduces memory allocations.
Speed up the creation of PSObjects in CSV cmdlets by
- Use the overload Add(PSMember, bool prevalidated) for all objects except the first when adding the `NoteProperty` members.
- Add a new constructor to PSObject that preallocates the `_instanceMembers` collection with an initial capacity.
- Improve performance of AddToTypesXmlCache by avoiding an expensive copying of members just to check for the existence of one of them, perf is significantly increased, and allocations are reduced.
- Reduce allocations and GC pressure by preallocating and reusing `StringBuilders` and `List<string>` for line parsing in CSV cmdlets.
- Use `List<string>` instead of `Collection<string>` to get fewer virtual calls and better inlining.
- Reduce allocations by using a preallocated value factory in `TypeTable.GetMembers(ConsolidatedString types)`.
- Replace a `Linq.Any()` with a `List.Count > 0` in binder code.
The main gain is from taking advantage of the fact that all objects created by `Import-Csv` have the same shape (the same properties).
Before the fix the TryConvertTo() is implemented in terms of Convert(), but with wrapping exception handling. This is costly performance wise. By inlining the implementation of ConvertTo(), and getting access to the FigureConversion output we can determine upfront on at least some occations that a conversion is not available.
Before the fix when using Get-Variable or Get-Alias cmdlets with the -Scope parameter with wrong value, the error message refers to 'scopeID' parameter instead of 'Scope'.
- Formatting file should be used for `MarkdownOptionInfo` object instead of the types file for adding script property.
- Downlevel windows consoles which do not support VT100 escape sequences should be handled gracefully.
- Add helpuri fwlink for cmdlets.
- Make `-Path` a positional parameter for `ConvertFrom-Markdown`
- make `-InputObject` a positional parameter for `Set-MarkdownOption`
A comment from the existing `Utils.IsComObject` mentions that: "We can't use System.Runtime.InteropServices.Marshal.IsComObject(obj) since it doesn't work in partial trust."
Partial trust is a concept of Code Access Security (CAS)/Security-Transparent. CAS and Security-Transparent are no longer supported in .NET Core, so we should use `Marshal.IsComObject` instead.
