e1d071dbfd Removed the broken code which claimed to lose the set[ug]id bits in
the !(pflag && setfile()) case for regular files unless the copy is
owned by the same user and group.  These bits have already been lost
(or never gained) in the correct way.  The code didn't actually lose
the bits; it depended on them being lost already (apparently in all
cases) and attempted to gain them as necessary, but it often gained
them (and sometimes collateral bits) when wrong:
- pflag && setfile() == 0 case (i.e., for a successful cp -p):
  setfile() copies all the attributes as correctly as possible (as
  specified by POSIX), and we sometimes messed up the up the mode by
  setting it again.  Also, if the file is immutable, then setting the
  mode again gave spurious errors (PR 20646).
- !pflag case.  If the target is created, POSIX requires it to not
  have the set[ug]id bits, but we sometimes copied them from the source.
  If the target already exists, POSIX requires its mode to be unchanged,
  but we sometimes copied the whole mode from the source.

b931f9b350 In the hope of saving others from hours of tedious recovery work,
document that cp still isn't very useful for recursive copies even
with the -R flag.  This is because hard links are broken by cp.

426e9c1dcc First set of fixes to keep egcs happy. These include {} around single
statement if blocks[*] when the else could be ambiguous, not defaulting
to int type and removal of some unused variables.

[*] This is explicitly allowed by style(9) when the single statement
spans more than one line.

40fc4ee2de Don't use mmap() for non-regular files, since st_size is only meaningful
for regular files.  This fixes recent breakage of cp'ing from /dev/zero.
/dev/zero doesn't support mmap(), but the device driver mmap routines are
not called for mapping 0 bytes, so the error was not detected.  mmap()
can't even be used for cp'ing special files that support mmap(), since
there is general way to determine the file size.

4faaa03777 Don't attempt to change owner/mode/flags that don't need to changed.
This should calm down attempts to `cp -p' to a nfs mount or some other
filesystem that doesn't accept flags or all combinations of flags.
It will warn if it fails to change flags though.

8abdc2eb40 Sweep through the tree fixing mmap() usage:
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

6a834fc3f1 Don't unlink the target file if the copy failed. This behaviour isn't
documented and is incompatible with gnu cp.  It has very few good effects
(it recovers some disk space) and many bad ones:
- special files are unlinked after certain errors.
- the data may not be recoverable if the source is a special file or fifo.
- unlinking destroys the target attributes as well as the target data.
- unlinking doesn't actually remove the target data if the target is multiply
  linked.

7658fd20d7 Don't strip off the last slash in the pathname "/". cp used to
stat the pathname "" in order to decide that the pathname "/" is
a directory.  This caused `cp kernel /' to fail if the kernel has
the POSIX behaviour of not allowing the pathname "" to be an alias
for ".".  It presumably also caused `cp /etc/motd /' to fail in
the unlikely event that "." is not stat'able.

Be more careful about concatenating pathnames: don't check that
the pathname fits until prefixes have been discarded (the check
was too strict).  Print the final pathname in error messages.
Terminate the target directory name properly for error messages.
Don't add a slash between components if there is already a slash.
