Don't short-circuit 0 sized stat entries if they don't belong to regular files.

enami | Don't truncate at microseconds while preserving timestamps.
One of motivation of this change is to make the behavior of test(1)
-nt/ot with preserved copy (like cp -p) closer to the NetBSD 6.
Of course whether full timestamps are kept or not depends also on
underlying file system.
The ifdef added in mv(1) since existing ifdefs was our local change
to compile it on solaris (though I couldn't test it):

manu | branches: 1.40.2;
Make cp -p and mv preverve extended attributes, and complain if they cannot.
Also introduce library functions for copying extended attributes from one
file to another:
- extattr_copy_file, extattr_copy_fd, extattr_copy_link, with FreeBSD style,
where a namespace is to be supplied
- cpxattr, fcpxattr, lcpxattr, with Linux style, where all namespaces
accessible to the caller are copied, and the others are silently ignored.

Non-standard option similar to Gnutools cp(1)

tron | Re-enable support for reading files of at most 8MB via mmap(2).
Write out the mmap-ed data in small chunks to avoid locking the output
file for a long time.
Suggested by David Holland on "source-changes-d" mailing list.
|
| 1.35 |
| 22-Oct-2010 |
pooka | Disable mmap path. With the current vnode locking scheme it has
a very annoying property: if the source media is slow (like a slow
network), the target file will be locked for the duration of the
entire max 8MB write and cause processes attempting to e.g. stat()
it to "tstile" (for several minutes in the worst case). Revisit
this if/when vnode locking gets a little smarter.
chs ok (although he would rather see vnode locking improvements,
but that's a slightly larger project)

jschauma | The last commit introduced a bug. Revert until that's found and fixed.
|

| 15-Jul-2006 |
jschauma | As suggested on tech-userlevel:
"-R" claims:
-R [...] Created directories have the same mode as the corre-
sponding source directory, unmodified
by the process' umask.
Make this actually true.
In addition, make '-P' (no symbolic links are followed) apply even if
'-R' is not specified. This allows users to overwrite symbolic links
with files and/or to copy symbolic links over a file without indirecting
through the link (ie a copy of a link turns the target into a link, not
a copy of the file pointed to by the source).

jschauma | As discusses a little while back on tech-userlevel:
If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.
While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

mjl | Correct behaviour in case of dangling symlinks: they would be (contrary
to what the manpage and POSIX say) copied as symlinks, even without -R.
Return ENOENT instead. Closes PR 6975 by Johan Danielsson <joda@pdc.kth.se>.
From FreeBSD: return correct error message if source directory is
unreadable; remove unnecessarily included headers.

wsanchez | Fix bug where "cp -f" didn't work.
It's suppsed to remove the file and then copy, which it wasn't doing.
But no wait, it turns out that the described behaviour in the manual doesn't
agree with POSIX. So we change the above fix and the manual to "try copy, and
if fail, try remove, then copy".
Fix bug where "cp -R" didn't work on read-only directories:
It would make the directory, set the mode, and not be able to write files into it.
Don't bother mmap()ing files of zero length. Was a workaround for a bug in Rhapsody
mmap(), which didn't get along with such files, but makes sense anyway.
Fix race condition where "cp -p" would set the mod time of a file before close()ing
the file, which would update the mod time and therefore screw up the "-p" idea,
except, of course, while running in gdb, which sucked.
Add -f option to usage message in binary and man page. Already documented in man page.
