Hello tbsky,

Can you give example code for a service you run, together with the command sequence you issue to control service installation, etc.? So far, I’ve not been able to get your code to work — but that’s likely because I don’t know enough about the Win32::Daemon module. :-(

In the meantime, perhaps you could try a module such as Test::LeakTrace. Here’s how I would proceed:

  • Wrap the top-level code into its own subroutine, say sub main
  • Change each exit statement into a return statement; for example, exit 1; becomes return 1;
  • Add the following at the top level:
    use Test::LeakTrace; { my $result; leaktrace { $result = main(); }; exit $result; }
  • Redirect program output to a log file, to facilitate analysis of the leak reports after the service has been stopped and uninstalled.

BTW, the following isn’t very informative:

print "Failed to install service: $!\n";

From the documentation, the correct way to report failure is like this:

print 'Failed to install service: ', Win32::FormatMessage(Win32::Daemon::GetLastError()), "\n";

Also, you have use Fcntl;, but I don’t think it’s actually used anywhere, is it?

Hope that helps,

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
