ScriptsToProcess is only processed for the first import

[alx9r]

The scripts named in ScriptsToProcess are processed only for the first module that is imported. This has the following implications for SessionStates that need to include the alterations caused by ScriptsToProcess:

• An Import-Module statement that usually causes changes to the active SessionState does not make those changes if the module named in the statement happens to already be loaded.
• Where more than one SessionState imports the same module, at most one of those SessionStates will have the alterations caused by ScriptsToProcess. Which one depends on the order the module importing occurs.

A workaround for this might be to use Import-Module -Force. However, if the module also involves PowerShell classes, then it might run afoul of #2505.

Steps to reproduce

ScriptsToProcess.psd1

@{
    ModuleVersion = '0.1.0'
    RootModule = 'ScriptsToProcessTest.psm1'
    ScriptsToProcess = 'ScriptsToProcessTest.ps1'
}

ScriptsToProcess.psm1

empty file

ScriptsToProcess.ps1

Write-Host 'ScriptsToProcessTest.ps1'
$v = 'importerscope.v'

Invoke the following

Remove-Variable v -ea si
Remove-Module ScriptsToProcessTest -ea si

New-Module m {
    Write-Host 'module'
    Import-Module ScriptsToProcessTest
    function Get-V {$v}
} | Import-Module

Write-Host 'global'
Import-Module ScriptsToProcessTest
"v: $v"
"Get-V: $(Get-V)"

Expected behavior

module
ScriptsToProcessTest.ps1
global
ScriptsToProcessTest.ps1
v: importerscope.v
Get-V: importerscope.v

Actual behavior

module
ScriptsToProcessTest.ps1
global
v:
Get-V: importerscope.v
