Re: [Bug-tar] 25: terminal input FAILED (iotty.at:29)

[Jack Howarth]

In case this helps, if I edit the section in tests/ttyemu.c

#if 0
# define DEBUG(c) fprintf (stderr, "%s\n", c)

to

#if 1
# define DEBUG(c) fprintf (stderr, "%s\n", c)

and remake tests/ttyemu, then the following occurs. In the tests
subdirectory of the tar-1.28 build, if I execute...

# ./ttyemu -t5 -i/dev/null /sw/bin/tar -x
closing in
sent EOT
/sw/bin/tar: This does not look like a tar archive
/sw/bin/tar: Exiting with failure status due to previous errors
closing master
child exited

that is the output from the installed tar-1.26 release at /sw/bin/tar.
If I do the same with the newly built tar-1.28 release in ../src, I get...

# ./ttyemu -t5 -i/dev/null ../src/tar -x
child exited
closing in
closing master
