Misuse of shell builtins (?) #22

Closed blambeau closed 12 years ago

blambeau commented 12 years ago

Hi,

All tests relying on exec seem failing under standard *nix config (cfr. http://travis-ci.org/#!/blambeau/posix-spawn) Typical example:

pid = _spawn('exec 2>/dev/null 101>&1 102>&2 || exit 1', :out => :close, :err => :close)
assert_process_exit_status pid, 1

which results in an exit status of 2 (misuse of shell builtins), not 1. I must confess that I'm not sure to understand what the test above is supposed to test (that out cannot be redirected? or err? or both?).

Any hint on this?

This is probably related to #6

Ooops sorry. I thought I've read all existing issues before submitting this one, something has failed in my process. I obvisouly close this one. Thanks

Does it work if you install bash instead of dash?
