Labview CLI hangs and does not leave memory

[pawhan11]

Hello,

I experience strange problems when using labviewcli - sometimes it hangs forever and must be terminated.

So i try to spawn it as process using powershell but when I run broken build process never ends and has to be terminated.

$arg = [string]::Format(' -OperationName ExecuteBuildSpec -ProjectPath "{0}" -LabVIEWPath "{1}" -Verbosity Detailed -LogFilePath "{2}" -TargetName "{3}" -BuildSpecName "{4}"',$projectPath,$labviewPath,$logPath,$buildTarget,$buildSpecName)
        
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = "labviewcli"
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $arg
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    $done = $p.WaitForExit($timeoutSec*1000)

My understanding is that after build fails log is generated and process should end just like when build works

I can confirm that log is generated with fail message: ExecuteBuildSpec operation failed.

In current situation it will wait full timeout despite fact that build failed and labviewcli process should be long gone.

Issue solved, it was caused by not reading redirected outputs

    #format labviewcli args
    $arg = [string]::Format(' -OperationName ExecuteBuildSpec -ProjectPath "{0}" -LabVIEWPath "{1}" -Verbosity Detailed -LogFilePath "{2}" -TargetName "{3}" -BuildSpecName "{4}"',$projectPath,$labviewPath,$logPath,$buildTarget,$buildSpecName)
    #setup process
    $pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = "labviewcli"
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $arg
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    $errTask = $p.StandardError.ReadToEndAsync()
    $outTask = $p.StandardOutput.ReadToEndAsync()
    $done = $p.WaitForExit($timeoutSec*1000)

    if ($done -eq $false)
    { 
        $p.Kill() 
        throw 'labviewcli exceeded build timeout'
    }
    else
    {   
        if($p.ExitCode -ne 0)
        {
            Write-Host 'build failed: '(Get-Content -Path $LVlogPath)
            throw 'build failed'
        }
        else{ Write-Host 'build succeeded'}
    }
