There are three copies of each test in the 'testsuite' file,
and you should change all three copies consistently.

Or, you can run the test by hand, by looking in the appropriate
*.at file and executing its commands one by one.

This is the segment of pipe.at that I tested against ...

mkdir directory

genfile --length 10240 --pattern zeros --file directory/file1

genfile --length 13 --file directory/file2

tar cf archive directory

mv directory orig

cat archive | tar xfv - --warning=no-timestamp | sort

echo "separator"

cmp orig/file1 directory/file1

echo "separator"

cmp orig/file2 directory/file2],

So I cd into tests and ran the following commands:

$ mkdir directory

$ ./genfile --length 10240 --pattern zeros --file directory/file1

$ ./genfile --length 13 --file directory/file2

$ ../src/tar cf archive directory

../src/tar: directory/file1: file changed as we read it

../src/tar: directory/file2: file changed as we read it

$ rm archive

$ truss ../src/tar cf archive directory 2> /var/tmp/truss.1 (attached)

$ mv directory orig

$ cat archive | ../src/tar xfv - --warning=no-timestamp | sort

directory/

directory/file1

directory/file2

$ cmp orig/file1 directory/file1

cmp: EOF on directory/file1

$ cmp orig/file2 directory/file2

cmp: EOF on directory/file2

$ ls -al orig/*

-rw-r--r--    1 brottk   sysadmin      10240 Aug 18 09:34 orig/file1

-rw-r--r--    1 brottk   sysadmin         13 Aug 18 09:34 orig/file2

$ ls -al directory/*

-rw-r--r--    1 brottk   sysadmin          0 Aug 18 09:34 directory/file1

-rw-r--r--    1 brottk   sysadmin          0 Aug 18 09:34 directory/file2

$ ../src/tar tvf archive

drwxr-xr-x brottk/sysadmin   0 2011-08-18 09:34 directory/

-rw-r--r-- brottk/sysadmin   0 2011-08-18 09:34 directory/file1

-rw-r--r-- brottk/sysadmin   0 2011-08-18 09:34 directory/file2

Looks like tar isn't putting anything but zero-byte files into the archives - which of course would make all the tests related to contents fail.
