- 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
* Including test cases to test include/exclude recursion
* Swap optional parameter for overload
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 native command receives the arg ".\test 1" as .\test 1" as the last \" is treated as escaping the quotes. Fix is to add an extra backslash to escape the last enclosing quote.
Code guarded by the following defines is ancient and has never been
used, so removing.
