[wpkg-users] Remove problem, wpkg checks success before remove completes

[Mike Moynihan]

I am having a problem with the wpkg.js checking for the status of the remove, before the remove completes.  

It works like this.
1.  Add the package
2.  Run the wpkg process which installs the package
3.  Remove the package, expecting it the next run of wpkg to uninstall it
4.  Run the wpkg process, which uninstalls the package ***
5.  The "check" after the remove occurs BEFORE the uninstall completes, so the package remains in the wpkg.xml file
   <here begins the problem>
6.  Run the wpkg process
7.  The package will check for the install before the removal, which will fail
8.  wpkg installs the package
9.  wpkg removes the package
10.  The uninstall completes before the recheck is done, the package remains in wpkg.xml
11.  successive runs of wpkg.js repeats the install / uninstall

This is a simple package, it's the one used in the WPKG QUICK INSTALL guide.  The remove command runs as a separte process, returning control back to wpkg.js before it has completed.  This causes the issue, as wpkg.js checks the install status immediately after the uninstall command returns control.

Is there a command switch that will cause the uninstaller to not return control until it completes?  Is there a way for wpkg to handle this?

I execute wpkg.js in a batch file via windows job scheduler.  Here is the info regarding the job, including the debug info written to the log.

wpkg.bat:
set software=\\server\software
cscript \\server\wpkg\wpkg.js /synchronize /debug > c:\wpkg.log

Package for DIA:
  <package id='dia' name='Dia Diagram Editor' revision='1' reboot='false' priority='800'>

    <install cmd='"%SOFTWARE%\dia\dia-setup-0.96.1-9.exe" /S'/>
    <upgrade cmd='"%SOFTWARE%\dia\dia-setup-0.96.1-9.exe" /S'/>
    <remove cmd='"%PROGRAMFILES%\dia\dia-0.96.1-9-uninstall.exe" /S'/>
  </package>
