scoop uninstall blocked when app is running

[deevus]

Example:

$ scoop uninstall openssh
uninstalling openssh (5.4p1-1)
removing shim for scp
removing shim for sftp
removing shim for slogin
removing shim for ssh-add
removing shim for ssh-agent
removing shim for ssh-keygen
removing shim for ssh-keyscan
removing shim for ssh
couldn't remove ~/appdata/local/scoop\apps\openssh\5.4p1-1: it may be in use

I'm thinking that users should be able to uninstall apps regardless of whether it is running or not - which means that we need some way of stopping services before uninstalling, so that the user doesn't need to figure it out themselves.

Agreed! But then there should be a way to add services in the first place not ?

First thing to do when uninstalling should be check for directory is in use. With information about folder is in use and two options: (it would require --force parameter for uninstallation)

1. Some aggresive uninstallation with process killing
2. just exit and let user manage of killing.

I could think only using Get-Process. Something like:

$procs = Get-Process -FileVersionInfo -ErrorAction SilentlyContinue | ? { $_.FileName -like '$dir`*'}
# or
# Create some hashtable from Get-Process with ID as key and Path as Value Get-Process | Select-Object Path, ID
if ($procs.Count -gt 0 -and !$forceParam) {
     abort 'Folder is in use. if you want to let scoop kill all process use unisntall -f'
} else {
    #Kill all process, which are running and continue uninstallation
    $procs | ForEach-Object { Stop-Process $_ }
}

@r15ch13 Do you have better solution?

Good idea 👍

It's a bit faster when the -FileVersionInfo isn't used. We don't need the file version for this. The Path property is enough.
Warning the user and do nothing would be the best way. This should also be implemented in the update process to skip running programs.
