| Subject: | Windows shell hardcoded to obsoleted 'command.com' (t/run test 19 fails on XP x64) |
t/run test 19 fails on XP x64 complaining that it can't find 'command'.
This is because the Windows shell has changed from command.com to
cmd.exe. In earlier versions of XP 32-bit both were available, but in
the 64-bit version command.com has been removed. This probably also
applies to later versions of the OS. I haven't found authoritative
documentation on which versions of Windows no longer have command.com.
The problem occurs due to this code (in 0.82 at line 1653 of lib/Run.pm):
if ( Win32_MODE ) {
@args = ( [ qw( command /c ), win32_parse_cmd_line $_[0] ] );
}
If this is changed to:
if ( Win32_MODE ) {
@args = ( [ qw( cmd /c ), win32_parse_cmd_line $_[0] ] );
}
Then the test will pass. However, this is not an acceptable patch
because it would break older OS which do not have cmd.exe. The OS
version needs to be checked before deciding whether to use command.com
or cmd.exe. With this change, all tests pass.
Without this change:
