wait-for-process.cmd

• Location: %WPKGSOFTWARE%\wpkg\tools\waitforprocess.cmd
• Purpose: Some (un)installers spawn a child process, but the wpkg command terminates and then wpkg continues on to the next line. This is not helpful! Thus, we have a helper script that sits in an infinite loop and only exits when the named process terminates
• Example usage:

<install cmd='%WPKGSOFTWARE%\wpkg\tools\waitforprocess.cmd Au_.exe' />
<install cmd='%WPKGSOFTWARE%\foo\bar\setup.exe' />
<install cmd='%WPKGSOFTWARE%\wpkg\tools\waitforprocess.cmd Au_.exe' />

• Note: the rationale for having three commands in that order is:

1. wait for any pre-existing Au_.exe process to finish (usually this will be a no-op)
2. run setup.exe which we've determined somehow will spawn Au_.exe
3. then wait for the Au_.exe to finish, which we are pretty confident can only be the child spawned in line 2 because we waited for any other Au_.exe processes we might have in line 1 Whilst there's a narrow window for another Au_.exe to start executing between line 1 and 2, in practice this formulation seems to work rather reliably.
