Subject cvs commit: httpd-test/perl-framework/Apache-Test Changes
Date Mon, 12 Apr 2004 19:34:14 GMT

  Modified:    perl-framework/Apache-Test/lib/Apache TestUtil.pm
               perl-framework/Apache-Test Changes
  Log:
  Use function prototypes in Apache::TestUtil functions t_cmp() and
  t_is_equal() to handle the case when an argument to the function, is a
  function call itself which may return undef (previously had to
  explicitly force a scalar context to get the undef value). The idea
  was borrowed from Test::More.

  -When comparing to a return value from a function, that may return an
  -C<undef> value, there is a catch -- in the list context the C<undef>
  -value disappears and you end up comparing with the next argument.
  -Therefore you can either explicitly call the function prior to
  -comparison:
  -
  -  my $received = foo();
  -  t_cmp($expected, $received, "may return undef")
  -
  -or use a scalar context:
  -
  -  t_cmp($expected, scalar foo(), "may return undef")
   
   This function is exported by default.

   Fixed a Windows-only segment which would result in a
   'use of uninitialised value' error if a hash being traversed
   had an entry with a key but an undefined value.  [Ken]
