Re: API? Or Make PowerShell Work?

[Pavel Lyalyakin]

Hello Adam,

Could you please tell us what automation tools do you plan to implement?
What management tasks do you want to automate and how?

The most likely reason why you are seeing the exception in the first
example is because the session created via *InitialSessionState.Create()*
does not include the definitions of the built-in commands (such as
*Export-ModuleMember*) which are required to successfully load and execute
commands from the CDXML module.

Could you please try the following code snippet that creates the session
using the InitialSessionState.CreateDefault() method that automatically
includes the necessary definitions for such built-ins?

// Or InitialSessionState.CreateDefault2(), see
// https://docs.microsoft.com/dotnet/api/system.management.auto
mation.runspaces.initialsessionstate.createdefault2
var session = InitialSessionState.CreateDefault();
session.ImportPSModule(new[] { "VisualSVN" });

using (var runspace = RunspaceFactory.CreateRunspace(session))
{
runspace.Open();
using (var invoker = new RunspaceInvoke(runspace))
{
var output = invoker.Invoke("Get-SvnRepository");
}
}

Re: API? Or Make PowerShell Work?

[Adam Humpherys]

Odd. I went back to using just the basics:

ps.AddCommand("Get-SvnRepository");
Collection output = ps.Invoke();

And now it's working. Initially, it told me it found the command in a 
module that hadn't been imported yet. But now it's working. So that's a bit 
weird.

API? Or Make PowerShell Work?

[adam]

I found one old message (from 2008) that asked for an API And I'm curious 
if this is in consideration.

We're building some automation tools to free up some developer time for 
managing SVN repositories in VisualSVN. I've been trying to use the 
PowerShell cmdlets from within a Windows service but it's not working very 
well.

But maybe if I can figure out what's wrong with the PowerShell execution 
then that will be good enough.


using (PowerShell ps = PowerShell.Create())
{
var psSession = InitialSessionState.Create();
psSession.ImportPSModule(new string[] { "VisualSVN" });
var ps_rSpace = RunspaceFactory.CreateRunspace(psSession);
ps_rSpace.Open();
var ps_invoker = new RunspaceInvoke(ps_rSpace);

Collection output = ps_invoker.Invoke("Get-SvnRepository");
}

at ps_rSpace.Open() I get an error: 

Cannot process Cmdlet Definition XML for the following file: C:\Program 
Files\VisualSVN Server\PowerShellModules\VisualSVN\SvnRepository.cdxml. 
Value cannot be null.
Parameter name: key ---> System.Xml.XmlException: Cannot process Cmdlet 
Definition XML for the following file: C:\Program Files\VisualSVN 
Server\PowerShellModules\VisualSVN\SvnRepository.cdxml. Value cannot be 
null.
Parameter name: key ---> System.ArgumentNullException: Value cannot be null.

I just upgraded to VisualSVN Server 3.8.0.

The Windows service will have a web interface/rest api so we can hook up 
our dashboard to it. Any ideas?

Thanks.
