2344	Tar Revert Pipe Drain Patch	willimmn	lfs-book@…	"CLFS is using two other Tar patches that apply for 1.21.

The first one, tar-1.21-manpage-1.patch, just makes a Tar manpage, and I don't think LFS will use it anyday.

The second one, tar-1.21-revert_pipe_drain-1.patch, is a patch that is considered to be in LFS. Why? As a example with unpatched Tar 1.21, download this example tarball: (of Glibmm, BTW)

ftp://ftp.gnome.org/pub/gnome/sources/glibmm/2.18/glibmm-2.18.1.tar.bz2

And try to unpack it by running this command:

bzip2 -dc glibmm-2.18.1.tar.bz2 | tar xof -

Tar runs with no error, however, run strace and you will get this output:

{{{
write(1, ""glibmm-2.18.1/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0""..., 4096) = -1 
EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
+++ killed by SIGPIPE +++
}}}

Look at this output closly and you will see that bzip2 acualy died because of a broken pipe. Now you see why this patch is a good idea for LFS? It is attached with this ticket."	defect	closed	normal	7.0	Book	SVN	normal	fixed
