I /thought/ I had resolved the problem by exporting TAR_OPTIONS=--hard-dereference.

I believe my only choice at this point is to forbid "make dist" if tar is detected to be old (less than 1.29), and keep doing --hard-dereference. I open to new ideas though. :-) >> >> Using "tar-ustar" format for distribution you are supposed to raise some >> of the limits of the "v7" tar format but retain portability.

I don't think this solution is worth the trouble in my case, since the directory included has a deep and complex structure (hence some files surpass 100 characters).

BTW: the german translation of the help output for that gtar option is rubbish.

In ustar link name must fit into 100 characters and the file path can be theoretically max 256 (if it is splittable correctly into prefix/name). You seem to have *directory* in some distribution sensitive variable, like: # Directory contains 'file' and 'link -> file'. EXTRA_DIST = directory .. Because if you had: EXTRA_DIST = directory/file directory/link then automake (via 'cp -p') would follow the link for you. In case of directories (before the actual 'tar ch' happens) automake copies the directory recursively by 'cp -fpR' [2] into temporary directory. Could we add '-L' option to this cp call (dist target is not supposed to be portable to everywhere and -L is POSIX)? Obviously, the archive bloat is not something automake tries to avoid. Anyway, I don't feel the handling of symbolic-links this way is correct. Don't we wan't to use something like $LN_S [autoconf manual] in such cases?

IMO, the Using "tar-ustar" format for distribution you are supposed to raise some of the limits of the "v7" tar format but retain portability. Indeed, the length limit for regular files used to be 256 characters [2], and since all symlinks were stored as files that was universal. Now that symlinks are stored as hard links, the limit is 100 characters for those, thus I've hit this problem.

What solution you exactly propose? Note that 'h' tar option is used for dist from Y1996 commit [1] and its removal is unlikely. It is quite portable and it, as the "default", works for many packages. What is not clear to me also is your motivation to change GNU tar to behave differently, or to change something so old in automake. IMO, the reason why you hit this issue is not the "hardlinking" change itself, but rather just small mistake of the maintainer who did not read STDERR tar's warnings while doing 'make dist'. We could make those warnings more obvious.. is that what you want? [1] http://git.savannah.gnu.org/cgit/automake.git/commit/?id=7930983ab1c620 Pavel

Of course, and that's what one would expect, cp makes copies by default, and the
copies have a different inode from the original.
I was referring to something like this:
touch blah
ln -s blah link_to_blah
mkdir dir
cp -a --dereference blah link_to_blah dir
This creates two hard links in dir, to the same new file. ("-a" attempts to
make "cp" act as much like "tar" as it can.)

Tar's current behavior is compatible with these other > utilities, whereas its old behavior was incompatible. Well out of the utilities you mentioned, only "cp" actually writes something, so it's related to the issue with tar. So I tried the behaviour of --dereference in cp: $ touch blah $ ln -s blah link_to_blah $ cp --dereference link_to_blah blah2 The result is that "blah" and "blah2" have different inode! So --dereference causes the symlink to be dereferenced to a separate file, *not* to a hardlink of the source. But in tar, --dereference causes a symlink to be dereferenced as a hardlink to the source file. So how is their behaviour consistent? BTW, my version of "cp" is: $ cp --version cp (GNU coreutils) 8.21 Thanks, Dimitris

This is not the right way to go for collecting files for a distribution.
In former times, I distributed symlinks with my distro tarballs but now I
include shell scripts that create the symlinks if needed and on platforms that
do not support symlinks, these shell scripts automatically try to create
hardlinks.
Maybe you should contact the respobsible person for your distro tarball.

But when the tarball is extracted, two files with same inode are created, which is kind of unexpected behaviour - at least for me - after creating the tarball with --dereference, i.e. I've explicitly asked to follow symlinks. And it beats the purpose some users have been using --dereference - to avoid storing links which have more restrictions (e.g. 100 char limit). > Using -hard-dereference bloats the tar image, but if that's a price you're > willing to pay then you have a solution to the problem. Indeed that's what I chose as workaround, compression deals well with duplicated information so size bloating was minimal. Thanks, Dimitris

I believe I've read that it is for portability, because symlinks are handled in a variety of manners in different tar implementations. However as seen above, what actually happens is that GNU tar stores the symlinks as hardlinks. Because the total path length of the hardlinks is more than 100 characters, they get truncated due to "ustar" format limitations (ustar format is chosen using the "tar-ustar" automake option). Please notice that removing "-h" fixes the problem. Symlinks are stored properly as their length is much smaller than 100 chars (because they are relative symlinks). Another workaround (the one I chose to use) is to pass the --hard-dereference to GNU tar in order to store the content of the files itself, avoiding all kind of links, and maintaining best portability. So I've added the following lines in my Makefile.am: TAR_OPTIONS = --hard-dereference export TAR_OPTIONS Regarding GNU tar, I've read at [1] and [2] that this behaviour was introduced recently, but is the intended behaviour. [1] https://bugs.launchpad.net/ubuntu/+source/tar/+bug/887107 [2] http://lists.gnu.org/archive/html/bug-tar/2011-11/msg00025.html My opinion is that it's really deceiving, given what the man page mentions: "follow symlinks; archive and dump the files they point to". It took me a while to figure out what those "hard link" messages mean, looking if I introduced hard links by accident. And since the hard links have no direction, some messages show the linking direction reversed, which made the issue even stranger. Why is such behaviour desirable? Are the reasons important enough to break expectations of users? Thank you in advance, Dimitris
