Dear tar people,
I felt today into trouble after an upgrade to 1.15.91 version of tar on my
Debian GNU/Linux machine.
I'm running a little bit complecate environment (Debian-> UserModeLinux->
loopback mounted file as ext3) where extractions of a tar archive with
sym-links fails (only 0 byte files are there). Tar extraction is not
interrupted!
The tar arhive is extracted within UserModeLinux on the loopback mounted fs.
I invested some time to identify the problem because I thouhght is a problem of
me. Now here is my patch to fix TAR:

+++ lib/timespec.h 2006-07-20 08:22:57.000000000 +0200

- : a.tv_nsec - b.tv_nsec);
+ : 0);
}
# if ! HAVE_DECL_NANOSLEEP
---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---
For my opinion is to accurate to check nano seconds (nsec) to identify files
with stat(), lstat() and fstat() in src/extract.c when process symbolic links!
I get all the time a difference in the UserModeLinux -> loopback mounted fs
while extracting (maybe my machine is too slow AMD3.2GHZ). Despite that why
it's important to diff in nano seconds ?
Looking for a solution,
Raphael Bossek
