nit: can OpenChannel fail?

[aedla, 2013/12/05 23:16:21]

It can't. Well, at least for POSIX, the channel has already been set up for us
before fork. If it hasn't been set up, we can't see the error at this point.
GlobalDescriptors::Get() will DLOG(FATAL) and we'll die later in
ReplayProcess::OnChannelError().

+  if (!replay.OpenTestcase())

return EXIT_FAILURE or 1 to indicate failure.

[aedla, 2013/12/05 23:16:21]

Done.

+
+  replay.Run();
+  return 0;

[Tom Sepez, 2013/12/05 19:05:49]

nit: return EXIT_SUCCESS just because its more portable.

[aedla, 2013/12/05 23:16:21]

Done.
