Revision history for IPC::Exe

1.007    2009/05/05
         - Changed: removed POSIX::_exit() because it got in the way of threads.
           Unfortunately, END blocks are performed as a result of die() or exit().
           I haven't found a reliable way to avoid END blocks inside a thread.
           Addressed by updating CAVEAT section in pod.

         - Added: $IPC::Exe::is_forked to tell if code is not in main process/thread.
           Added is_forked test.

         - Fixed: smoke test failures duplicating STDIN. We'll see if the fix works.
         - Added: check for undef values in LIST. Added undef_cmd test.
         - Minor pod corrections.

1.006    2009/05/02
         - RT #45413: A chain of trivial scripts is stuck under Win2k, works under Linux
           Threaded fork-emulation has limitations.
           Addressed by updating CAVEAT section in pod.
           Added *_pipe tests to account for this.

         - RT #45263: wrong constant intermediate exit code
           Fixed: $? was getting clobbered by waitpid(). Added exit tests.

         - &READER is now called with ($child_pid, LIST) as arguments.
           $child_pid allows waitpid($_[0], 0); to be called in &READER to set $?

         - Deprecated 'exec' option in %EXE_OPTIONS. No more use of system().
         - Changed: improved non-Unix quoting. Added quoting test.
         - Added: manually flush STDERR/STDOUT after &PREEXEC.
         - Added: use POSIX::_exit() upon failed exec to avoid calling END blocks.
         - Added: use lib "../lib"; to examples/*.pl
         - Minor changes to "README" and "Makefile.PL".

1.005    2009/04/21
         - Fixed: unknown open() mode '>&' to be compatible with Perl 5.6+.
         - Minor changes.
         - Added: LICENSE to "META.yml".

1.004    2009/04/20
         - Fixed: found = in conditional, should be ==.
           use warnings; doesn't understand what I mean.

1.003    2009/04/20
         - Changed: exec() failure code sequence.
         - Fixed: unknown open() mode '<&' to be compatible with Perl 5.6+.
         - Fixed: minor mistakes in pod.
         - Added: PREREQ_PM for POSIX module.

1.002    2009/04/17
         - Fixed: barewords STDIN/STDOUT/STDERR while "strict subs".
         - Extracted examples into new EXAMPLES section in pod.
         - Included "META.yml" in dist.
         - Extracted license info from "README" into its own file "LICENSE".
         - Skip 'background' test in "02_IPC-Exe.t" if not in DEBUG mode.
           Testing bg() requires manual inspection.
