Add support to experimental features
RFC: https://github.com/PowerShell/PowerShell-RFC/pull/114
Goals:
Allow experimental features to be declared by PowerShell engine and modules.
Allow experimental features to be enabled via powershell.config.json
Allow Function, Cmdlet, parameters and parameter sets to be shown to the user or hiden from the user depending on whether the associated experimetnal feature is on or off.
Allow discover experimental features using cmdlet Get-ExperimentalFeature
Update PowerShell Direct to try pwsh then fallback to powershell
- Forward port changes from Windows Powershell to fall back
- change the order from powershell->pwsh to pwsh->powershell
fixes#7237
* Use `nameof` where appropriate
* Factor out a repeated `entry.Key.ToString()` call
* Use a `StringBuilder` in the `ToString()` method
* Dissect a trick comparison method into something simpler
* Use HashCode.Combine() method
Previously, we limited use of UseShellExecute when starting a new process to only Windows Desktop. However, CoreFx now supports UseShellExecute (appropriately calling `open` on macOS and `xdg-open` on Linux) so we can have a consistent code and remove some of the existing redundant code or unnecessary limiting code.
* The major refactoring changes are:
- In `ModuleIntrisic.cs`, remove unneeded Windows-PowerShell-only code.
- In `ModuleUtils.cs`
- use the new API `Directory.GetDirectories(string path, string searchPattern, EnumerationOptions enumerationOptions)` and `Directory.GetFiles(string path, string searchPattern, EnumerationOptions enumerationOptions)` to enumerate files and sub-directories within a directory path.
- remove the unused parameter `bool force` from `GetDefaultAvailableModuleFiles(bool force, bool isForAutoDiscovery, ExecutionContext context)`
- refactor the method `GetModuleVersionsFromAbsolutePath`. Add more comments and rename the method name.
- In `ModuleCmdletBase.cs`, refactor the method `GetModuleForNonRootedPaths` to `GetModuleForNames` to simply its implementation.
- In `PSModuleInfo.cs`
- group the declarations of `Declared*Exports` fields together
- rename `_detected*Exports` fields to `Detected*Exports` to group them together. They are internal fields and used outside `PSModuleInfo`.
* There is some perf improvement after this refactoring change:
- For `Get-Module -ListAvailable`, there is about 36% speed improvement for 94 default modules.
- For `Get-Module -ListAvailable -All`, there is about 14% speed improvement for totally 600 module files.
- For `Get-Module <name> -ListAvailable -List`, there is over 17x speed improvement for finding 13 modules from 600 modules. This is because we now filter names using the module file before creating a `PSMdouleInfo` object.
PSRP currently relies on XML for the transport messages. When using PSRP over SSH, if the target side fails, it sends back a text message. PSRP sees this and doesn't know what to do so it throws
a generic message which makes troubleshooting the issue more difficult. Change here is to throw
the text message which now looks like:
>new-pssession : [test-machine] There is an error processing data from the background process. Error reported: Invalid argument '-np', did you mean:.
Previously:
>new-pssession : [test-machine] There is an error processing data from the background process. Error reported: Cannot process an element with node type "Text". Only Element and EndElement node types are supported..
Since it's processing one line at a time, not able to get the whole message.
* [FEATURE] Allow Basic Auth over HTTPS
* WSManTransportManager.cs: Simplify HTTPS check
Update comment in test to refer to the right exception type.
* Disable test until limi crash fo selected connection error paths is fixed
* Use Hex format for defining the expected HRESULT
The fix causes a problem in debugging. When stepping over the scripts in debugging mode, the debugger will stop at the switch statement condition expression twice at the very beginning -- one for evaluating the condition, and one for iterating the condition.
Table formatter was overly aggressive in removing padding so even right justified output (default of numbers) gets incorrectly stripped of padding. Fix is when right justified, always add padding (because it's right justified, there's never trailing whitespace).
* Implement location history feature for Set-Location.
This makes it possible to go back to the last directory using 'cd -',
which is exactly the same syntax as on Linux shells.
* Use an existing stack implementation instead of relying on an environment variable and move logic for 'cd -' into the internal class of SessionState.Path.SetLocation
Keep the (additional) setting of an environment for Unix system in case of mixed usage of cd and Set-Location to provide consistency.
* Use a bounded stack with a limit of 1000 and adapt tests.
Remove setting environment variable on Linux as discussed in PR.
* Fix test: use get-location explicitly to avoid subtle difference in the path string (e.g. an additional slash at the end)
Make syntax to .net call of environment consistent with surrounding code
* Move initialization of _workingLocationHistoryStack into constructor of SessionStateInternal and set the limit to 20 as discussed in PR 5051.
* Make new BoundedStack class in engine utils internal
setdate.cpp was incorrectly assigning an int to a struct, fixed to initialize struct zero'd
update the typegen project in the bash script
added some help text at top of script for someone trying to build it
updated runtime to linux-musl-x64 instead of linux-x64 as Alpine distro uses the musl libc libraries instead of glibc which is used by most distros.
* Fix error when using Get-ChildItem c:
* Fix New-Item test issue.
* Add tests for Get-ChildItem cmdlet.
* Add tests for New-Item cmdlet.
* Fix tests for New-Item cmdlet.
