Subject cvs commit: httpd-test/perl-framework/Apache-Test/lib/Apache TestRun.pm
Date Sun, 06 Jan 2002 06:55:57 GMT
stas        02/01/05 22:55:57

  Modified:    perl-framework/Apache-Test/lib/Apache TestRun.pm
  Log:
  - use exec() to call itself for setting ulimit (this solves the lost
    status problem).
  
  - direct all exit() calls in PerlRun.pm into one place, for two reasons:
    + Enable easier debug in the future
    + functions like server->stop don't return 0/1 but -1..N, so it helps
      to handle the exit arguments properly.
  
  - in addition all exit() calls ends in exit_shell, to which you may
    want to pass a real return status which can have quite a few values.
