When calling powershell from powershell (called the minishell for historical reasons), the arguments are passed as a base64 encoded string.
The native command parameter binder was trying to match up the ast to the argument value, which in this case, doesn't make sense.
The fix is to ignore the ast during parameter binding for this case of calling powershell from powershell.
Fix#5733
The symbol resolver was properly resolving the type to the class
definition, but that resolution was ignored at runtime because we used
the string instead of the ITypeName - the ITypeName kept the reference
to the class definition.
Fix#5661
Make PowerShell Core reads group policy settings from different registry keys (Windows only) and the configuration files (both Windows and Unix).
- On Windows, move to different GPO registry keys.
- On both Windows and Unix, read GPO related settings from the configuration file `powershell.config.json`.
- On Windows, the policy settings in registry take precedence over the configuration file.
- Enable policy controlled logging and transcription on Unix.
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.
- Remove the unneeded base type;
- Rename 'ConfigPropertyAccessor' to 'PowerShellConfig';
- Move 'PowerShellConfig' to the namespace 'System.Management.Automation.Configuration'
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.
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.

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
