  1. Inconsistent Array Initialization Behaviour

    Creating an array of arrays as below works well:

    $myArray = @(
    @(1,2,3),
    @(4,5,6)
    )
    $myArray[0] #outputs 1, 2, 3
    $myArray[1] #outputs 4, 5, 6

    $myBuggyArray = @(
    @(1,2,3)
    ,@(4,5,6)
    )
    $myBuggyArray[0] #outputs 1
    $myBuggyArray[3] #outputs 4, 5, 6

    I wouldn't expect the order of line break & comma to impact the behaviour of the command / can't find any documentation stating that it should.

    • Graphical bug in PSVersion 5.1.16299.248

      Hi there

      I've never used the powershell very much. Today I discovered this graphical bug in the rendering of the console text output:
      https://i.imgur.com/H40F15W.png
      This bug was very confusing at first. Then it just kept getting more irritating.
      The bug appears when I scroll up and down, at the bottom of the window. Sometimes text gets cut off at the sides too, but only if I change the window width.
      I think I remember I had similiar issues years ago on a different computer.

      I couldn't find anything related on google. Maybe I used the wrong search terms?

      Although totally…

        • Some new default cmdlet parameters?

          We have -ErrorVariable and -WarningVariable. To capture verbose output to a variable, you can $VerboseRecords = (Write-Verbose -Verbose "test") 4>&1 # and find it in $VerboseRecords.Message, but wouldn't it make sense to add a -VerboseVariable? Maybe even a -WriteHostVariable?

          • Add 'StopExisting' as a valid argument for New-ScheduledSettingsSet -MultipleInstances

            Only Parallel, Queue, and IgnoreNew are supported right now. One would expect that the option available from the Task Scheduler GUI would be available in the powershell interface.

            Steps to reproduce

            $a = New-ScheduledTaskSettingsSet -MultipleInstances StopExisting

            Expected behavior

            The task's multiple instances policy is set to kill existing tasks before starting another instance.
            Actual behavior

            value "StopExisting" to type "Microsoft.PowerShell.Cmdletization.GeneratedTypes.ScheduledTask.MultipleInstancesEnum".
            Error: "Unable to match the identifier name StopExisting to a valid enumerator name. Specify one of the following

            • PowerShell does not fully convert a hashtable passed to a PSCustomObject parameter

              When passing a hashtable to a function parameter that expects a PSCustomObject, PowerShell does not fully convert the hashtable to a PSCustomObject type.

              function Test-1 {
              param(
              [PSCustomObject] $Foo
              )

              Write-Host "`$Foo is a PSCustomObject: $( $Foo -is [PSCustomObject] )" -Fore Green
              Write-Host "`$Foo has these properties:" -Fore Green

              foreach ($prop in ($Foo | Get-Member -MemberType NoteProperty| Select -ExpandProperty Name))
              {
              Write-Host "`t$prop" -Fore Green

              • [Bug] Bitwise AND operation on long value is ignored when Most-Significant 32 bits is masked with zero

                [Bug] Bitwise AND operation on long value is ignored when Most-Significant 32 bits is masked with zero

                Sample Code to replicate issue:

                [BitConverter]::GetBytes([BitConverter]::ToInt64(@(1,1,168,192,255,255,255,255), 0) -band 0x00000000ffffffff)

                Should return: @(1,1,168,192,0,0,0,0)
                Actually returns : @(1,1,168,192,255,255,255,255)

                • Remote powershell should not return error for FileSystem validation

                  SCENARIO

                  The error belongs to I drive which should have been returned as a warning and not error. The invoke does not even use the I drive so why fail on it (we in this case dont even want the invoke to have access…

                  • Classes do not support data hiding.

                    I am grateful for the addition of classes in PS, and I know why PowerShell classes do not support true data hiding, but it is a significant shortcoming. It does not allow full control of setting a property for example. I can write my own class method for setting it, but it can be changed outside of that method. And if that method also updates the value of another class property, it can get changed directly, without going through the desired logic so the class method can be bypassed.
                    And it is nice to have the get_ and set_ automatically…

                    • BUG: Is it an error or not an error; Inconsistent output and error message

                      The following codes were extracted to test a simple $arrayName += $NewObject code that kept replacing the entire array with each new $NewObject.
                      # *** START
                      $dataArray = @() # Array to store data

                      • get-childitem should show listed directory, not the current one

                        reproduce:
                        go, for example, to c:\windows directory and type

                        get-childitem c:\users

                        -> get-childitem first line says Directory: c:\windows, and then it lists users directory contents. Is this intended behavior? If it is, it's quite confusing. Same with earlier versions. This is also very confusing when using filter to search subdirectories.

                        I would expect "directory:" to show the listed directory's name, not the current.

                          Add an optional switch to show the progress of an ongoing copy operation. Could be useful for large operation. Basically replicate as much information as the Explorer does, without the performance graph.

                          • BUG: PowerShell stderr redirect to file inserts newlines

                            If I run the following command in PowerShell:

                            $ .\long_error_message.exe 2>error.txt

                            , I get spurious newlines in error.txt. I generated a full repro and extremely clumsy solution at [1]. Can we declare this behavior as a bug? Note that cmd.exe operates exactly as one would expect.

                            • Inconsistent behaviour with [System.Environment]::GetFolderPath in Invoke-Command

                              Invoke-Command somepc.somedomain.net -credential Administrator -Scriptblock {
                              ([System.Environment]::GetFolderPath("MyDocuments") + "\WindowsPowerShell\Modules")
                              }

                              Run on a remote computer as-is this returns the module path for the Administrator user, as expected. However...

                              Invoke-Command somepc.somedomain.net -credential Administrator -Scriptblock {
                              Write-Output ([System.Environment]::GetFolderPath("MyDocuments") + "\WindowsPowerShell\Modules")
                              }

                              This instead returns the path for MY account, lgulliver, running locally. You get the same result passing this to New-Item and presumably other cmdlets.

                              • Powershell Core on IBM Power-series Hardware

                                With Powershell Core v6 in GA status, it would be nice to see it scaled to other architecture, including OpenPOWER (This would include IBM's Power8 and the more recent Power9 hardware). This would allow management of OSes on that hardware with Powershell Core.

                                • Low performance when transferring long arrays between PSSessions

                                  I faced with the problem when I tried to recive long array (file system entries) from remote pssession. It is obvious that Powershell has problems with it.
                                  For reproduce it you should run next code:

                                  $session = New-PSSession localhost

                                  $arrayLen = 1024000
                                  Measure-Command{
                                  Invoke-Command -Session $session -ScriptBlock {
                                  Write-Host ("Preparing test array {0} elements length..." -f $using:arrayLen)
                                  $global:result = [Byte[]]::new($using:arrayLen)
                                  [System.Random]::new().NextBytes($result)

                                  }
                                  } |% {Write-Host ("Completed in {0} sec`n" -f $_.TotalSeconds)}

                                  Measure-Command{
                                  Invoke-Command -Session $session -ScriptBlock {
                                  Write-Host ("Transfer array ({0})" -f $using:arrayLen)
                                  return $result
                                  } | Out-Null
                                  } |% {Write-Host ("Completed in {0} sec`n" -f $_.TotalSeconds)}

                                    Consider this code:

                                    [int]$end = 100
                                    [double]$Increment = 0.1

                                    1..$End | Foreach-Object {[double]$t += $Increment ; "$_ $t"}

                                    I'd expect the output always to give the line number and the current total, but look what happens at lines 60 and 101:

                                    • Implement `runas.exe` counterpart with `netonly` and `NoNewWindow` switches

                                      I need to open Powershell console (within the same window) as different user with /netonly option known from the runas.exe command. I would like to avoid typing manually passwords, because I will use this console to run some scripts automatically.

                                      As far as I know if it currently impossible.
                                      I added appropriate question on SO: https://stackoverflow.com/questions/48882958/powershell-open-new-console-as-different-user-in-the-same-window-runas-neto

                                      • Add-Content should create folder but returns error

                                        According to this documentation Add-Content should create a folder when it does not exist: "This command creates a new directory and file and copies the content of an existing file to the newly created file."

                                        https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/add-content?view=powershell-5.1

                                        However, I get an error: "Add-Content : Could not find a part of the path 'C:\tests\test134\logs\test134.log'."

                                        Seems like a clear issue to me. Either in the documentation or the functionality.
