- Adds `LanguagePrimitives.IsNullLike()` method to account for `DBNull.Value` and `NullString.Value` so that they can be considered the same as a null value where sensible in PowerShell.
- Updates `-ne` and `-eq` binders to treat `DBNull.Value` and `NullString.Value` as equal to null/AutomationNull.
- Update code paths for comparing objects in LanguagePrimitives to ensure consistency with how the `-eq` and `-ne` binders work when calling LanguagePrimitives methods to do the comparisons.
- Make `LanguagePrimitives.IsNull()` and `LanguagePrimitives.IsNullLike()` public methods.
- Added tests for null behaviours in `NullRepresentatives.Tests.ps1`
This PR does 4 things:
* Adds a new cmdlet `New-PSBreakpoint` which creates new `Breakpoint` objects and writes them to the pipeline
* Adds a `-Breakpoint` parameter to `Debug-Runspace` which will receive `Breakpoint` objects
* Makes the constructors for `*Breakpoint` public for use with the API
* Makes `Debugger.GetBreakpoint(string id)` and `Debugger.GetBreakpoints()` public since `SetBreakpoints` is public
Note: `New-PSBreakpoint` and `Set-PSBreakpoint` (which already exists) are similar... but `Set-PSBreakpoint` also sets the breakpoints in the _current_ runspace. This is not ideal if we want to set breakpoints in a _different runspace than the current one_.
## PR Context
The "Attach to process" debugging experience in the PowerShell extension for VSCode is _ok_ but it's not great.
The reason it's not great is due to the `BreakAll` feature of PowerShell debugging which, when you run `Debug-Runspace`, will break at the first piece of code that gets run. This is not ideal when you "Attach to process" _and then_ run your code in the other runspace.
Today, the experience drops you in `PSReadLine`'s psm1 if PSRL is available or in the vscode PowerShell helper psm1.
It's unexpected for the user and not ideal.
This PR will allow the extension to pass in the breakpoints that need to be set initially with `BreakAll` turned off for none of this silly behavior.
### Silly behavior example
If you want a repro, try this:
PowerShell instance 1:
```
Enter-PSHostProcess -Id $otherprocesspid
Debug-Runspace 1
```
PowerShell instance 2:
```
./runfoo.ps1
```
Note that you end up NOT `runfoo.ps1`
Major changes are:
- Make all commands return 'ConfirmImpact.None' if `SupportsShouldProcess` is not set to `true`.
- Update some cmdlets to explicitly use `ConfirmImpact.Low`.
- Update `DefaultCommands.Tests.ps1` to test for 'ConfirmImpact' level.
[breaking change]
Major changes are as follows:
- Add `Enable-ExperimentalFeature` and `Disable-ExperimentalFeature` cmdlets.
- Remove `-ListAvailable` from `Get-ExperimentalFeature`.
- Add `ArgumentCompleter` for `Get-ExperimentalFeature` cmdlet.
- Refactor some existing Experimental Feature tests.
- Make `ConfigScope` public and renamed `SystemWide` to `AllUsers`. Also update experimental feature code to prefer the current user config over the all user config.
Major changes are as follows:
- Avoid `SecuritySupport.IsProductBinary` and unnecessary AMSI/suspicious code scan at startup time
- Update `CompiledScriptBlockData.IsProductCode` to avoid unnecessary calls to `IsProductBinary`, which attempts to retrieve catalog signature of the target file.
- Update `PerformSecurityChecks` to skip AMSI and suspicious code scan for the `.psd1` file that contains a safe `HashtableAst` only.
- Use customized `ReadOnlyBag` instead of `ImmutableHashSet` so that we can avoid loading the `System.Collections.Immutable.dll` completely.
- Replace `SHA1` with `CRC32` when generating module analysis cache file name
- This remove the loading of `System.Security.Cryptography.Algorithms.dll` at startup
- Move `ConvertFrom-SddlString` to C# to remove the `Utility.psm1` file.
- Crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation
- Even pwsh with crossgen assemblies spends a lot time in jitting at the startup, about `191.6ms` comparing with `24.7ms` for Windows PowerShell.
- Jitting `Microsoft.ApplicationInsights.dll` takes about `51.6ms`.
- By crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation, the jitting time drops to about `98.9ms`.
There a some differences in support of named pipes for Windows and non-Windows. Named pipes on Unix have a 104 character path limit. On macOS, the `$env:TMPDIR` (on my system) is already 49 characters; corefx adds 12 more. Since AppDomainName isn't really used, changed it from `DefaultAppDomain` to `None` to shorten the name. Need to keep it since Windows PowerShell expects it. Changed `starttime` part of pipe name to 8 hex characters which is to provide uniqueness to the pipe name.
PowerShell serialization has a list of known PowerShell types. When an object is deserialized containing a known type it tries to deserialize the object to that specific type and throws an exception if it can't succeed. SemanticVersion only exists in PSCore6 so when remoting from Windows PowerShell or importing clixml generated from PSCore6 that contains SemanticVersion, it fails.
With this fix, it will be rehydrated as a "PSObject" with "Deseriealized.System.Management.Automation.SemanticVersion" in the 'TypeNames' in both Windows PowerShell and PowerShell Core.
Convert ShouldBeErrorId to Should -Throw -ErrorId in PowerShell tests.
Get rid of try { } catch { } formula to assert that errors were thrown.
Small fixes in tests to obey the new Pester -Parameter syntax.
The Test-Connection cmdlet works on Windows and Unix.
Implemented:
Ping
Continues Ping
Traceroute
Detect MTU size (seems don't work on Unix because of .Net Core issue)
Connect to TCP port
Not jet implemented:
I'm putting this off for the future.
Detect blackhole routers
PingPath
Additional considerations
As you can see in the tests .Net Core has issues in API implementation. As a result, some tests are skipped on Unix. There is also one issue on Windows. Related comments added to tests.
I'm going to open an issue(s) in CoreFX repo.
I think we should break the feedback into two parts:
scripting functionality
interactive functionality (display output)
Now I have implemented the output to the screen as the progress bar and as text (without ETS) - we have to decide what is best to use.
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
* Test fixes and changes needed to support Pester 4.0.8
* Replace 'Should Contain' with new 'Should FileContentMatch' assertion
Explicitly check for string creation with write-output
* Use the current version of pester and install it in modulesDir
* Simplify logic for relative path test.
Multiple '..' is not needed for a relative path, a single one will do. Also, on multi-drive systems using split-path -noqualifier will probably do the wrong thing with regard to constructing a correct path.
Remove extraneous Should Not Throw test, if this throws, the test will fail, we don't need to explicitly assert the not throw
* In some environments it is possible that computer name is 'localhost', so that should be allowed
* [feature] Add link for migrating tests from Pester v3 to v4
Fix up capitalization and white space issues
Change one test to check FullyQualifiedErrorId rather than just `Should Throw`
* [feature] update invoke-item test to handle the case where multiple notepad processes are running
* Fix spelling issue with Pester 4x, calling it Pester 4 should be sufficient
* Add Remove-Alias Command. Add Remove-Alias Test. Add Remove-Alias to .psd1.
* Fix code-formatting. Fix ErrorAction on Remove-Alias instead of preference variable. Remove unnecessary Get-Alias calls. Switch Force parameter to auto property. Add ValueFromPipeline to Remove-Alias Name parameter.
* Remove empty lines. Add Remove-Alias to Unix Module .psd1. Add Remove-Alias to approved Commands test. Remove Try/Catch for SessionstateException. Add WriteError for aliasnotfound exception.
* Add ErrorAction Stop to all Get-Alias and Set-Alias Cmdlets in all tests for consistency. Add Should BeNullOrEmpty to "should throw if alias does not exist" test to verify that foo alias really is not there before removing it.
* Changed Remove-Alias parameter Name to String-Array. Changed Cmdlet Process Logic to work with String Array. Added Alias named "ral". Added test case for Alias "ral". Added "ral" Alias to list of approved Aliases. Replaced foo and bar values in all tests with better names.
* Remove "ral"-alias test as this is covered in DefaultCommands.Tests.ps1. Add test for removing multiple alias at once. Fix wrong curly braces positioning.
* Remove $FullCLR in DefaultCommands.Tests.ps1 for Remove-Alias and "ral" alias.
* Add Alias "ral" to Remove-Alias Cmdlet.
* Remove "ral" alias as this is handled by using the [Alias()] attribute on the Remove-Alias Cmdlet.
* Replace alias names used in Remove-Alias Cmdlet tests with GUIDs to avoid collisions
Since DCOM is not supported in corefx there was a great deal of dead code in the computer cmdlets.
This PR removes all vestiges of DCOM support from:
- Rename-Computer
- Restart-Computer
- Stop-Computer
removing about 4500 lines of dead code. Also, tests are updated to provide more complete coverage.
I also removed test-connection completely to make way for @iSazonov upcoming PR to improve coverage in tests, I created some test hook code which will test the cmdlet code without actually calling the WMI method to restart/rename/stop the system
* Remove AllScope from most default aliases
To speed up scope creation, I removed AllScope from most default
aliases.
This results in a 15-20% speedup for:
function foo {}
for ($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.
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.
- Exclude 'Get-PSHostProcessInfo', 'Enter-PSHostProcess' and 'Exit-PSHostProcess' from Unix platforms.
- Update tests and add additional cmdlets need to be excluded
