Hi,
what would be the best way to test stuff like two binaries
communicating via a pipe, FIFO or such with DejaGNU? The gfortran
testsuite has by now quite extensive coverage of all the weird and
quirky corner cases of Fortran I/O behavior, but practically all these
tests are done using regular files. Over the years we've had some
embarrassing bugs in handling non-seekable files like terminals,
FIFO's, and pipes. I believe these would have been quickly caught if
only we had testing coverage.
(Something which works only on x86_64-unknown-linux-gnu and perhaps a
few other "mainstream" targets where we can expect the presence of a
"normal" shell environment etc., while not optimal, is certainly a lot
better than what we have now.)
Any ideas? See also the mail below which discusses the same issue.
