NamedPipeConnectionInfo <= Enter-PSHostProcess #881

TylerLeonhardt · 2019-03-18T20:37:30Z

Before, we relied on Enter-PSHostProcess... I noticed that this wasn't working and instead the GeRunspace function would return results from the current runspace instead.

This switches to using NamedPipeConnectionInfo API way of invoking something on a remote runspace.

@SeeminglyScience let me know if you see anything wrong with this in the scope of the threading model... I think it will be fine since it's a totally separate runspace...

+                {
+                    var psCommand = new PSCommand().AddCommand("Get-Runspace");
+                    StringBuilder sb = new StringBuilder();


Use var here - channeling my inner @rjmholt. :-)

-                    foreach (var p in runspaces)
+                    // Create a remote runspace that we will invoke Get-Runspace in
+                    using(var rs = RunspaceFactory.CreateRunspace(new NamedPipeConnectionInfo(pid)))


Will this work with all supported versions of PowerShell?

Good catch... this use to be a runtime check using Enter-PSHostProcess but now it's an assembly load check...

This will work in PowerShell 5.1+ so it's not a problem in this PR.

But when I backport I need to ifdef this properly...

LGTM :)

Just some optional nits

runspaces = ps.AddCommand("Microsoft.PowerShell.Utility\\Get-Runspace").Invoke<PSObject>();

Consider using a more descriptive variable name like runspace or even pso.

Edit: didn't realize this was existing code, but maybe still worth fixing.
