tar 1.14 had a bug related to not correctly padding files that
got smaller during archiving. Doing this:
diff -bur tar-1.14/src/create.c tar-1.16.1/src/create.c
shows this change:
@@ -868,39 +1034,54 @@
quotearg_colon (st->orig_file_name),
STRINGIFY_BIGINT (size_left, buf)));
if (! ignore_failed_read_option)
- exit_status = TAREXIT_FAILURE;
- pad_archive (size_left);
+ exit_status = TAREXIT_DIFFERS;
+ pad_archive (size_left - (bufsize-count));
return dump_status_short;
}
}
which I suspect is the change mentioned in the ChangeLog:
2005-05-12 Sergey Poznyakoff <[EMAIL PROTECTED]>
* src/create.c (dump_regular_file): Correctly pad archive members
that shrunk during archiving. Repored by Frank Heckenbach.
So I recommend trying a newer version of tar. However, I don't know
if OSX adds features for resource forks to tar, so the vanilla GNU
tar might not handle resource forks. Does a newer OSX have a newer
tar version?
