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.

When a child is receiving SIGSTOP, eval continues with the next

and you get the prompt back), it is wrong for a shellscript, which
just continues with the next command, never again waiting for the

make more processes (by wosch).
The fix is not to return from a job wait when the wait returned for a
stopped child while in non-interactive mode. This bahaviour seems to
be what bash2 and ksh implement. I tested for correct behaviour for
finnaly killing the child with and without forgrounding it first.
When not foregrouding before killing, the shell continues with the

These functions, upon reflection and discussion, are too generically

Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world

the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be

add a -j flag that tells date not to try to set the date. This allows you
to use date as a userland interface to strptime.
example:
TZ=GMT date -j -f "%a, %d %b %Y %T %Z" "Sun, 08 Nov 1998 02:22:20 GMT" +%s
which is the standard format for Last-modified headers in HTTP requests.

This is a seriously beefed up chroot kind of thing. The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.
For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact: "real virtual servers".
Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.
Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.
It generally does what one would expect, but setting up a jail
still takes a little knowledge.
A few notes:
I have no scripts for setting up a jail, don't ask me for them.
The IP number should be an alias on one of the interfaces.
mount a /proc in each jail, it will make ps more useable.
/proc/<pid>/status tells the hostname of the prison for
jailed processes.
Quotas are only sensible if you have a mountpoint per prison.
There are no privisions for stopping resource-hogging.
Some "#ifdef INET" and similar may be missing (send patches!)
If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!
Tools, comments, patches & documentation most welcome.
Have fun...

and CPU runtime because it can't access the user area via /proc/<pid>/mem.
This is because the uarea is not mapped into the process address space
at USRSTACK on the alpha like it is on the x86.
Since I'm haven't been able to wrap my brain around the VM system enough
to be able to figure out how to achieve this mapping, and since it's
questionable that such an architectural change is correct, I implemented
a workaround to allow ps(1) to read the uarea from /dev/kmem using
kvm_read() instead of from the process address space via kvm_uread().
The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact
the x86. (Note that top(1) probably uses this same gimmick since it works
on FreeBSD/alpha.)

pattern matches will occur at offset zero of the source string. The bug causes
the input source string pointer to be incremented by the offset of the end of
the match, instead of it's length. The fix is to only increment the pointer by
the length of the pattern match (eo-so).
Of course, the one example in the man page shows a situation where the match
occurs at offset 0.

/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.

tag support. These changes have been tested with a Breeze Hill
Q47 DLT and a DEC DLT2500 media changer. The latter has no
volume tag support.
The chio(1) command was updated to include various flags to the
status subcommand. These flags can be used to select additional
information to be displayed (like volume tags).
A new chio(1) subcommand named 'voltag' has been added which allows
for changes to volume tags inside the media changer controller.
This could not be tested as the Q47 does not provide the functio-
nality.
