* Lookup uname/gname if not provided by the archive (I copied the
uname/gname lookup cache from bsdtar)
* Format device number instead of size for device nodes
* Format date.
There's still a few improvements that I could copy from
bsdtar, especially the locale-aware safe_fprintf() code
and the locale-aware setup for day_first date formatting.
(And, of course, I need to think through a clean way to
push this stuff down into libarchive.)
Thanks to Peter Wemm for reminding me of this overlooked TODO item.
In particular, this fixes the oddity that -dumpl would apply
umask to copied dirs (which are created in the target tree)
but not to "copied" files (which are only linked). After
this change:
$ ls -ld a a/b a/b/c
d--x-w-r-- 3 tim tim 512 Jul 29 20:08 a
drwxr----x 3 tim tim 512 Jul 29 20:09 a/b
dr----x-w- 2 tim tim 512 Jul 29 20:09 a/b/c
$ (echo a; echo a/b; echo a/b/c) | cpio -dumpl o
$ cd o
$ ls -ld a a/b a/b/c
d--x-w-r-- 3 tim tim 512 Jul 29 20:08 a
drwxr----x 3 tim tim 512 Jul 29 20:09 a/b
dr----x-w- 2 tim tim 512 Jul 29 20:09 a/b/c
link, just ignore the -l option and copy the file instead.
In particular, this should fix the COPYTREE_* macros used in the
ports infrastructure which use -l to preserve space but often get
used for cross-device copies.
A new implementation of cpio that uses libarchive as it's back-end
archiving/dearchiving infrastructure. Includes test harness;
"make check" in the bsdcpio directory to build and run the test
harness.
