On windows, group policy settings from registry takes precedence over the configuration file.
If a policy is not defined in GP, then we query from configuration file.
Issue #4029 exposed two problems when failing to load libpsrpclient.
WSManAPIDataCommon.ctor was not identifying the binary that failed DLLImport; hindering diagnosability
PrioritySendDataCollection.Clear() would throw a NullReferenceException when called from the finalizer after an error path.
This change addresses both of the above:
Guard against null arrays in PrioritySendDataCollection.Clear() - called from finalizer in error paths.
Diagnosability: Log the DllNotFoundException in WSManAPIDataCommon ctor and also include it as the internal exception when throwing PSRemotingTransportException.
- Remove the unneeded base type;
- Rename 'ConfigPropertyAccessor' to 'PowerShellConfig';
- Move 'PowerShellConfig' to the namespace 'System.Management.Automation.Configuration'

Underpinnings to make calling of Extension methods /Linq easier from PowerShell.
Enables the following that previously had to be done via reflection.
class M {
[int] Twice([int] $value) { return 2 * $value }
[int] DoubleSum([int[]] $values) {
return [Linq.Enumerable]::Sum($values, [M]::Twice)
}
}
Each PSMethod is created as with a unique type for the combinations of method signatures in the MethodInfos it represents.
PSMethod<T> where T is a MethodGroup<>, potentially recursive in the last template argument.
This way, we can determine by just looking at the type of a PSMethod if there exists a conversion from the PSMethod to a delegate.
CoreCLR doesn't call finalizer on process exit. PowerShell relies on the CLR finalizer to clean up state on exit. In this case, a Runspace pool was not closed or disposed and any pipeline worker threads created to run concurrent scripts won't end, causing the hang. The same thing can happen if any individual Runspace is created to run a concurrent script and is not closed.
We cannot use the `AppDomain.DomainUnload` event because it's not supported by the default load context. The `AppDomain.ProcessExit` event is also not helpful since it is only called during application exit which means threads already have to be cleaned up.
The fix introduces a static property called `PrimaryRunspace` to `Runspace`. When the PrimaryRunspace is closing it means that the PowerShell session is ending and on exit clean should be performed. The static property `PrimaryRunspace` can only be set once per process.

- Revert refactoring changes so that it doesn't break remoting to Windows PowerShell 5.1
- Fix the rest of the supported types for remoting
- Put remoting sensitive private members in a descriptive region
This PR is divided into the following areas:
1. Add/Rename the PowerShell/Windows ETW manifest to the repo and change both the provider id (guid) and name. See #4939.
The manifest is at tools/resxgen/PowerShell-Core-Instrumentation.man
2. Generate a resx file containing the string resources needed for logging ETW events to syslog.
This is accomplished by tools\resxgen\resxgen.psm1 and resxgen.ps1. The tool generates two files
A resx file containing string resources for each message string from the manifest. This is generated in the System.Management.Automation\gen directory.
A C# class (EventResource) that provides the mapping between the integer event id and the associated string resource name. The file is generated in the System.Management.Automation\CoreCLR directory with a compile-time condition of UNIX
NOTE: The EventResource.cs class generated by resgen is explicitly ignored in the csproj file; it is not used.
3. SMA\utils\tracing\PSSysLogProvider.cs
Implements the abstract LogProvider class and is the syslog equivalent of PSEtwLogProvider. The class contains a number of logical methods for logging lifecycle, health, and normal events.
4. SMA\utils\tracing\SysLogProvider.cs
This is the Syslog equivalent of ETW's log provider class and implements a Log method versus ETW's EventWrite. It is also responsible for resolving event ids to resource names and performing the Syslog call. There is a large comment block in the class XML doc that describes the types of log output it produces.
5. SMA\utils\tracing\PSEtwLog.cs
PowerShell's current implementation is tightly coupled to this class; with code calling it directly for all events. To simplify integration of syslog, I updated the class to create an instance of PSSysLogProvider on Linux and removed the Linux-specific stub file.
6. SMA\engine\PropertyAccessor.cs
This class provides a wrapper around PowerShellProperties.json and has been extended to have Unix-specific assessors for configuring logging. Note that the file is expected to be in the $PSHOME directory to ensure SxS.
Currently, there are four configuration properties:
- LogIdentity - the string identifier for the source application. This defaults to 'powershell' and can be configured to enable distinguishing between side-by-side installations.
- LogLevel - configures the tracing level (log level). Informational is the defauilt.
- LogChannels - used to enable operational and analytic logging. Operational is the default.
- LogKeywords - used to configure enabling tracing by keyword. All keywords other than `UseAlwaysAnalytic` are enabled by default.
NOTE: This will likely change. PowerShell sometimes confuses the analytic channel with this keyword and sends logging to the wrong channel. Once this is cleared up, `UseAlwaysAnalytic` and `UseAlwaysOperational` keywords will likely be removed.
Additional Notes:
1. The current implementation writes directly to syslog and writing to a separate log file is still pending.
2. The generated class and resx are not part of the build; instead, it is expected that Resxgen should be run when events are added to the manifest. To fully automate the process, resxgen will need to be updated to generate the other dependent enums such as 'PSChannel', 'PSEventId', 'PSTask', 'PSOpcode', etc. You will see parsing logic in resxgen.psm1 to prepare for that but it is not enabled at this point.
4. Documentation is pending that documents the format of the syslog output as well as associated configuration.
5. As mentioned at the start, tests are pending
This replaces the code that scanned a script block for suspicious strings.
The previous implementation:
* Tokenized input (generating many strings for garbage collection)
* Used multiple threads
This approach is based on Rubin-Karp and does not allocate any memory
other than a small array to hold the running hash values.
I tested the new and old approaches on 2200 files in the PowerShell repo.
The old code ran in about 1.8-2.1s (ignoring time spent reading files)
The new code runs in about 0.6s and is more stable due to no garbage.
Using the assembly name to hint at the source of the classes was
problematic in multiple ways.
This change stores the actual filename in an attribute on the assembly.
So for a given type, one can get the assembly this way:
[SomeType].Assembly.GetCustomAttributes() |
? { $_ -is [System.Management.Automation.DynamicClassImplementationAssemblyAttribute] } |
% { $_.ScriptFile }
Since DCOM is not supported in corefx there was a great deal of dead code in the computer cmdlets.
This PR removes all vestiges of DCOM support from:
- Rename-Computer
- Restart-Computer
- Stop-Computer
removing about 4500 lines of dead code. Also, tests are updated to provide more complete coverage.
I also removed test-connection completely to make way for @iSazonov upcoming PR to improve coverage in tests, I created some test hook code which will test the cmdlet code without actually calling the WMI method to restart/rename/stop the system
Previously we used IScriptPosition for context (e.g. error reporting)
during parameter binding, but in some cases we want more information, so
we'll use the Ast instead.
This change just adds the Ast, it doesn't make explicit use of it.
* Remove AllScope from most default aliases
To speed up scope creation, I removed AllScope from most default
aliases.
This results in a 15-20% speedup for:
function foo {}
for ($i = 0; $i -lt 100kb; $i++) { & { foo } }
I left AllScope of a few frequently used aliases because it does
make command lookup faster. If we introduce something like dynamic
sites for command lookup, then we could probably remove the rest
of the AllScope aliases.
This is a low-risk breaking change. One can ask for aliases at
a particular scope:
Get-Alias -Scope 1 nsn
This could now fail if the scope number doesn't correspond to global
scope.
The class CommandFactory served no real purpose in command lookup
other than to unnecessarily add a few frames to the call stack,
introduce an extra indirection, and add a couple of unnecessary
checks that essential instances like ExecutionContext are not null.
Added the following to the Get-Service command:
•BinaryPathName (Was suggested as ServicePath )
•Description
•UserName (Was suggested as LogOnAs )
•DelayedAutoStart
•ServiceStartupType
The ServiceStartupType was also added, providing the user access to use services like in services.msc , having Automatic , Automatic (Delayed Start) , Manual and Disabled as options (Also includes InvalidValue as an initial value for ServiceStartupType )
This unifies file encoding across the inbox cmdlets to be UTF-8 without a BOM for all platforms. This is a breaking change as cmdlets on windows have a number of different encodings. This supports better interoperability with tradition Linux shells as we are using the same encoding.
Validate that files are created with UTF-8 encoding without BOM
Update tests to validate Encoding parameter to new type and create new tests for
parameter type validation.
[Breaking Change] The '-Encoding Byte' has been removed from the filesystem provider cmdlets. A new parameter '-AsByteStream' is now added to indicate that a byte stream is required as input, or output will be a stream of bytes.
* Add depth to ProcessPathItems
* Honors capped recursion when using Include or Exclude filters with Get-ChildItem

Updated fwlinks to pull new help content for PSv6.
Fwlink for Microsoft.PowerShell.Core module is not updated since about_*help.txt is not available yet.
Unwrapping of 'ValueFromRemainingArguments' was being performed only for 'object[]' arrays (which covers the most common PowerShell binding scenarios) but could be skipped if a collection of any other type were passed to the parameter. This change unwraps 'ValueFromRemainingArguments' if the single element is a collection.
- Exclude 'Get-PSHostProcessInfo', 'Enter-PSHostProcess' and 'Exit-PSHostProcess' from Unix platforms.
- Update tests and add additional cmdlets need to be excluded
For PSCore 6, we are only supporting InitialSessionState. The RunspaceConfiguration APIs were already made internal. This PR removes all the code related to RunspaceConfiguration. This also means that some public APIs have changed. Was deciding between leaving the RunspaceConfiguration parameters and throwing Unsupported, but thought it was better to have it a compile-time error. This should simplify the code base.

The code in `AssemblyLoadContext.dll` doesn't need to be in a separate DLL anymore.
S.M.A.dll depends on `AssemblyLoadContext.dll`, so keeping that code out of S.M.A.dll doesn't help make S.M.A smaller size or less dependent. So the code in `AssemblyLoadContext.dll` is moved to `S.M.A.dll` and then we remove `AssemblyLoadContext.dll`.
The changes are:
- Move `CorePsAssemblyLoadContext.cs` to `src\S.M.A\CoreCLR\`
- Update `CorePsAssemblyLoadContext.cs` to get the test took moved to `Utils.InternalTestHooks` and update tests
- Update `build.psm1` and `.csproj` accrodingly
- Update `pwrshcommon.cpp` to remove `AssemblyLoadContext.dll` from the TPA list.
- `S.M.A.AssemblyExtensions` is removed as `PackageManagement` has finished their move to .NET Core 2.0. (I will work with Bryan to get the latest version uploaded to powershell-core)
It's to solve a side-by-side problem we have with powershell core. If a .NET Core version assembly has the same name as it's .NET ancestor in GAC, then even if you specify the file path to `Import-Module`, powershell core will still load the one in GAC because it tries 'Assembly.Load' first.
Now we change it to use `Assembly.LoadFrom` first when a file path is given, so it works for modules that have side-by-side assemblies.
Transcription was relying on reading the screen buffer to record output from native commands.
This resulted in an unhandled exception calling an unimplemented API on non-Windows.
The fix is to use redirected output/error if reading the screen buffer is not supported.
We check whether screen scraping is supported or not only when the application is running standalone.

When handling file redirection for CommandExpression, we don't call 'DoComplete' on the underlying PipelineProcessor of the FileRedirection object, and thus the EndProcessing method is not called on Out-File, which causes different behaviors between <expr> > out.txt and <expr> | Out-File out.txt.
The fix is to make sure 'DoComplete' is called after the stream output has been written to the redirection pipe.
Also fix another issue
This PR also fixes an issue that could mess up restoring the original pipes. Here is the repro:
PS> 1 *> b.txt > a.txt; 123
Cannot perform operation because object "PipelineProcessor" has already been disposed
The root cause is that we don't always restore pipes in the correct order. Please see the code changes in Compiler.cs for more details.

This round of cleanup focuses on the following areas
- Tab completion code

Changes in the rest affected files are mainly some corresponding changes due to the cleanup work in the above areas.
When dotting a script cmdlet, the locals of automatic variables from the `PSScriptCmdlet` is not set up in the current scope before parameter binding. The fix is to push the locals in `CommandProcessor.OnSetCurrentScope` and pop them in `CommandProcessor.OnRestorePreviousScope`, which will be called from `SetCurrentScopeToExecutionScope` and `RestorePreviousScope` respectively.
Summary of changes:
1. When a new local scope is used, currently we set the locals for `CommandProcessor` right before parameter binding (in `BindCommandLineParametersNoValidation`); we set the locals for `ScriptCommandProcessor` in `Prepare`. I moved both to the constructor, right after the new scope is created so that the code is more consistent.
2. In `CmdletParameterBinderController.cs`, we set up the `PSBoundParameters` and `MyInvocation` variables in `HandleCommandLineDynamicParameters` again, which I think is unnecessary because this method is only called from `BindCommandLineParametersNoValidation`, where the setup is done for the first time.
3. Currently, the locals will be set for dotted script cmdlet in `EnterScope()` and `ExitScope()`. Now, that logic is moved to `OnSetCurrentScope` and `OnRestorePreviousScope` of `CommandProcessor`. This not only makes sure that locals are set before parameter binding, but also is consistent with the `ScriptCommandProcessor`.
`Compiler.LoadModule` assumes that when `ps.HadErrors == true` the error stream is not empty. However, when `SilentlyContinue` is specified as the error action, the non-terminating error is not kept in `ErrorOutputPipe` of the cmdlet and thus does not appear in `ps.Streams.Error`. So when `ps.HadErrors == true` while `ps.Streams.Error` is empty, it suggests it's OK to ignore the errors because they are explicitly suppressed with `SilentlyContinue` error action.
So in my opinion, the expected behavior of `"using module .\mod.psm1"` in this case should be successful as if `ps.HaddErrors` is false.
* AlternateStreams support relies on pinvoke to win32 APIs which don't work on non-Windows and produces errors about not loading a DLL in the case of copy-item
* Address PR feedback, remove -Stream parameter for Unix added new -stream tests
* if/def out alternate stream syntax checks not applicable to Unix
GetMember/SetMember/InvokeMember operations on a COM object will generate code to unwrap the COM object if it's wrapped in PSObject. Due to a loose restriction, if you have a string wrapped to a PSObject with an ETS member of the same name, then the string PSObject will be unwrapped too and the ETS member will be lost. The fix is to use a more restricted rule by checking if the base object is a COM object.

Fixes#1193 for most scenarios. The remaining scenario to be addressed is the Nano Server bring-up scenario. To continue supporting that scenario, I left the Install-PowerShellRemoting script in place.
This change
1. Ports Enable-PSRemoting and Disable-PSRemoting to PowerShell Core
2. Adds side-by-side PowerShell Core remoting support to the PSSessionConfiguration cmdlets and PSRemoting cmdlets.
3. Ports PSSessionConfiguration tests
This change also introduces a behavioral difference. The PSRemoting and PSSessionConfiguration cmdlets are now context-sensitive and only work for endpoints that match the PowerShell type. For example, Get-PSSessionConfiguration, when running in PowerShell Core, will only return PowerShell Core WinRM endpoints. It will only modify PowerShell Core WinRM endpoints and cannot be used to configure Windows PowerShell endpoints.

To improve code clarity and give better error messages when using ValidateRange, you can now specify:
```
[ValidateRange(ValidateRangeKind.Positive)]

```
Valid kinds are:
Positive
Negative
NonPostiive
NonNegative
Make `System.Management.Automation references` to package `System.Security.Permissions`, which brings back `SecurityZone` and `System.Security.Policy.Zone`.
On CoreFx, UseShellExecute for Process start is false by default to be cross platform compatible.
In the case of a folder, Process.Start() returns Access Denied as it's not an executable.
On Windows, we can use the ShellExecute path to have explorer open the folder. On Unix, we use `xdg-open` and `open` for Linux and macOS respectively.
- Fix invalid value error message on some properties of ParameterAttribute to point to the specific properties.
- Avoid wrapping argument exception into not a useful 'requires' exception.
This change fixes 3 issues:
- According to [PowerShell Language Specification Version 3.0](https://www.microsoft.com/en-us/download/details.aspx?id=36389), as quoted: "_The result is the (possibly empty) unconstrained 1-dimensional array_", `@(...)` should only return `object[]` array.
- `@([object[]]$null).GetType()` fails with error `"You cannot call a method on a null-valued expression."`
- `@([System.Collections.Generic.List[object]]$null)` fails with error `"Object reference not set to an instance of an object."`
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'ForEach-Object' (alias is '%' or 'foreach')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Where-Object' (alias is '?' or 'where')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Select-Object' (alias is 'select')
- Fix PSScriptAnalyzer warnings of type PSPossibleIncorrectComparisonWithNull. Essentially, $null has to be on the left-hand side when using it for comparison.
- A Test in ParameterBinding.Tests.ps1 needed adapting as this test used to rely on the wrong null comparison
- Replace a subset of tests of kind '($object -eq $null) | Should Be $true' with '$object | Should Be $null'
Summary
----------
When the same script file gets executed in multiple Runspaces, the RuntimeType generated from the powershell class defined in the file will be shared among those Runspaces. For different Runspaces, different SessionState should be used to run the static methods.
Fix
---
We use the `SessionStateKeeper` to query for the correct `SessionState` to use for a static method call.
We already use `SessionStateKeeper` to track the `Runspace/SessionState` where a PowerShell class is defined, and thus we can leverage this for the static method invocation.
Currently `ValidateSetAttribute` accepts only explicit constants as valid values. This is a significant limitation. Sometimes we need to get valid values dynamically, ex., Azure VMs, logged-on users and so on. The PR add follow possibilities:
- pass a _custom type_ (a valid values generator) implementing `IValidateSetValuesGenerator` interface to get valid values dynamically.
- pass a _custom type_ (a valid values generator) derived from `CachedValidValuesGeneratorBase` abstract class to get valid values dynamically and _cache_ the list to share with other ValidateSetAttribute attributes.
Add the dynamic parameter `-FollowSymlink` to `Get-ChildItem`.
Add a mechanism for tracking visited directories.
Add native code to get device/inode information on Unix/Windows.
Add warning when refusing to enter an already-visited directory.
* the default XmlResolver will attempt to resolve external resources, recommendation is to explicitly set to null which
will raise exception if malicious xml attempts to cause xmlreader to access external resources
* added DTDProcessing and related to XmlReaderSettings
`AssemblyVersion` and `FileVersion` are now inferred from the `Version` property, which is inferred by `VersionPrefix`. So now both `AssemblyVersion` and `FileVersion` are 6.0.0.0 for each of PowerShell assemblies, and the `ProductVersion` and `InformationalVersion` are 6.0.0.
* address static analysis issues
- remoteRunspaces is not used TFS:10618323
