NEWS: what has changed recently with procps, in reverse cronological order.
Please send bug reports to [e-mail]


NEWS for version 2.0.7 of procps

SMP support has been added to top.  This adds one line to the screen
for every processor.  There is also an (off by default) field to show
the last processor that a process used that replaced the long-dead
LIB field.  Please send feedback, positive and negative, on these
changes to [e-mail]

The libproc soname has changed to 2.0.7 because of a structure
change required to add SMP support.

Two programs inspired by Solaris's /usr/proc/bin collection have
been added: pgrep and pkill.  By default, for FSSTND/FHS/LSB compliance,
these are installed in /usr/bin; if you want, you can change PROCDIR
in Makefile to move them.  You can also make a symlink from
/usr/proc/bin to /usr/bin if you like.

The Makefiles have been sanitized a bit more; they are now less messy
than they were.  There is less duplication between the Makefiles now.

The man pages that use tables have been fixed to work work broken
versions of man.

The old wmconfig file (specific to Red Hat) has been replaced with a
desktop file (common across GNOME and KDE).

sysctl returns an error code in a condition in which it didn't before,
and handles EOF correctly.

top now only loads System.map when it is actually going to make use
of it.

vmstat has its buffer size increased and handles page size dynamically.

w has its year display fixed to show the year 2000 as 00 instead of 0,
and to try harder to find a process to display.

watch has a fix for ncurses in recent versions of glibc, and expands
tabs so that they display correctly.

libproc tries to get the default page size from the system header
files, but still has a fallback.  It also has been extended to allow
applications to handle their own error reporting in some important
cases.  The pwcache has been expanded in size to correctly handle
user names longer than 8 characters.  It has been expanded to
provide the lproc field that shows up as top's LC field.  A segfault
when /proc is not mounted was fixed.  Missing files will cause
applications to exit with an error code instead of good exit code.
A warning when libproc cannot calculate the HZ value (probably due
to a kernel bug) has been supressed by default because it broke
people's scripts unnecessarily.  A 64-bit memory size reading
bug was fixed (/proc/meminfo was read incorrectly).

A couple of error messages in ps had newlines added to them.  ps
only opens System.map when it is going to make use of it.  The
full-page error message has been replaced with a shorter usage
message; the full-page command summary is available with --help,
and the usage message tells about --help; the full-page summary
is now no longer an error message and so it is sent to stdout
insteada of stderr.  Processes with run times longer than a day
now have their runtime displayed correctly.  ruser output was fixed.
An attempt was made to support one more piece of BSD syntax in the
command line arguments, where pids can follow options with no
intervening space.  The ps man page was made a bit more
internally consistent and typos fixed.  Fixed a segfault when the
PS_FORMAT environment variable was set wrong.


NEWS for version 2.0.6 of procps

Support for large-memory systems has been added.

LIBVERSION has been incremented because of an incompatible change
in the libproc interface, necessitated by the large-memory support.

A little more error checking in device idle time calculations.

The signames.h file is now properly built.

Fixed an almost-impossible file descriptor leak in libproc that
occasionally showed up in long-running top sessions.

The fix for top no longer depending on NR_TASKS in 2.0.5 was
broken; top would die with more than 204 tasks.  This has been
fixed.


NEWS for version 2.0.5 of procps

procps can build against the 2.3.18 kernel source; top no longer
depends on NR_TASKS.

skill/snice no longer complain on Linux/SPARC

sysctl no longer segfaults with -A; has a few parsing fixes


NEWS for version 2.0.4 of procps

sysctl can save/restore settings using /etc/sysctl.conf file

top has -p option and N and A commands.

vmstat doesn't mind interrupt counter overflow on long-running machines

ps can now sort by PCPU.


NEWS for version 2.0.3 of procps

Time calculations fixed (or at least improved...) for SMP machines.
In particular, hertz is calculated correctly.

ps doesn't mind terminal resizing happening while it runs.

sysctl is a nifty new program!  Try it!  Carefully!  :-)

w PCPU and WHAT output fixed.

top batch mode now works without a tty (for instance, via rsh).

new version of watch has a few new features like --differences.

sessreg removed; it belongs where it has been for a long time, in X.


NEWS for version 2.0.2 of procps

Removed xproc entirely; the only thing left there was XConsole, which
was equivalent to xconsole -file /proc/kmsg.  Added an XConsole shell
script which does
exec xconsole -file /proc/kmsg "$@"
so that folks who depend on XConsole won't be left behind.  This also
fixes the bug that XConsole effectively removed limitations on which
users were allowed to read /proc/kmsg without root having much choice
in the matter other than to remove XConsole...

Removed unused psupdate code (still available as part of procps-1.2.x
for anyone who wants to play with it).

Removed sessreg, as it is included in XFree86 and there is no reason
for the duplication.

Fixed version number generation so that it happens in one place.  I'm
tired of releasing versions that misreport their version number...


NEWS for version 2.0.1 of procps

Reverted my changes that had broken Albert's Unix98 compliance.

Major bugs fixed:
 o  ps now returns failure for "ps <non-existant-pid>"
 o  ps h has reverted to old linux behaviour except in BSD personality;
    --headers and --no-headers long options have been added
 o  watch buffer overrun fixed (no, not a security hole).

top has -b and -n options added.


NEWS for version 2.0 of procps

Thanks to Albert Cahalan for his rewrite of ps, and for making
the time for new development of ps that I just didn't have.  His
research into how ps worked on lots of different UNIX systems
really made this version much more usable for a lot of people.

Read ALL of Albert's comments regarding his 1.9.0 release.  If
you do not, you may be surprised when scripts fail.  I've tried
to prepare people for the worst of this by giving out the much-detested
  warning: `-' deprecated; use `ps aux', not `ps -aux'
message for roughly a year and a half.


NEWS for version 1.9.0 of procps

The ps command now supports simultaneous BSD and Unix98 syntax.
There have been many other changes in ps. (complete rewrite)

Red Hat users should check /etc/sysconfig/network-scripts/ifdown-ppp
for the bogus command "ps aul" and change it to "ps axl".

Scripts that make assumptions about character position are and
were broken because fields may overflow. Scripts should parse by
whitespace and use -o to get the best results. Command names for
swapped out processes are now shown in square brackets instead of
parentheses, as required by the Unix98 standard. This problem can
be avoided entirely by using a SysV format without -f, using the
BSD "c" option, or using the format specifier "comm" with -o.

Some uses of ps in /etc/rc.d/init.d/functions should probably
eventually be changed to stuff somewhat like the following, which
would eliminate the need for awk:

PS_PERSONALITY=linux dead=`ps -p $pid -o pid=`
PS_PERSONALITY=linux echo -n `ps -C $1 -o pid=`
PS_PERSONALITY=linux pid=`ps -C $1 -o pid=`

Obsolete files you may have: /etc/psdatabase, /etc/psdevtab,
~/.psdevtab, /usr/man/man8/psupdate.8 and /usr/sbin/psupdate.


NEWS for version 1.2.9 of procps

psupdate has been REMOVED from the default install.  You can put it back
if you want to by removing two comment characters in the Makefile, but
I'm not going to tell you which ones.  <RANT>If you can't figure it out,
there's a good chance that it won't build on your machine and I don't
want the bug reports.  One of the main reasons I have removed it is that
it is not necessary on a properly-maintained system (that is, System.map
exists and is correct) and 4/5ths of the bug reports I have fielded in
the past are from users who are not able to maintain a working system
complaining that it doesn't work, despite the fact that the INSTALL file
explains how to build it in different ways and how to disable it.</RANT>
I will delete without response all email asking me how to build psupdate.

ps now accepts and ignores the g option for those with fingers tied to
the g key from too much exposure to BSD.  :-)

Should build properly on ultrasparc -- two people sent the patch and
the second time I didn't notice that the patch went in reverted.  So
I have now reverted the reverted patch to get the right behavior.

More reliable command-line parsing in vmstat has been added.  If vmstat
didn't die for you before, you won't notice the difference...

Fixed a bug where arbitrary users might have been able to corrupt the
screen of arbitrary other users running top by creating processes with
weird arguments.

"ps ce" was missing a space character; fixed.


NEWS for version 1.2.8 of procps

procps.spec now uses buildroot, and can be built by non-root users.
This means that the default install targets had to change in the
makefiles so that the default install does not require root privs
otherwise.  Also changed all "bin" ownership to "root" ownership,
as kmem-ps has died out and folks won't be automatically doing
"chmod u+s /bin/ps" and making their systems insecure thereby.

XConsole no longer installed setuid root by default.  This is safer,
if less convenient.  Change it if you want to use it as non-root.

top had disgustingly buggy ^Z handling: you could only suspend once,
and if you had suspended, you could no longer read WCHAN information.
Both bugs are now fixed.

xcpustate removed -- it was a very old, obsolete version.
Get a new version from ftp://ftp.cs.toronto.edu/pub/jdd/xcpustate

Now looks for kernel symbols in loadable modules.

psupdate no longer included in RPM package; the theory is that
systems maintained with RPM probably are reasonably recent and
up-to-date and so psupdate is extraneous on those systems, only
adding an unhelpful dependency on a particular version of
binutils.

top printed two spaces instead of just one between command-line arguments.


NEWS for version 1.2.7 of procps

Security hole in XConsole fixed.

Works better with very long uptimes.

Fixed RPM spec file to have correct libproc soname.

skill -i works.

Knows about more major numbers for smart serial boards.

Fixed some small problems in top.


NEWS for version 1.2.6 of procps

Signal handling in top fixed in several ways.  Main effect: suspending
works correctly with glibc now.

Patch from Linus for change in some kernel structures to 64-bit.
This means that libproc has changed soname, as the proc_t data
structure has changed incompatibly.

File descriptor leaks in libproc were fixed.


NEWS for version 1.2.5 of procps

Potential security hole fixed: if there was no /etc/psdevtab on
a system, a user could put a link from /tmp/psdevtab to a file
owned by another user, and when that other user ran ps, the
file it pointed to would be killed.  This wouldn't work for
root because root would be able to create /etc/psdevtab first,
so arbitrary system files would not be killable.  This was fixed
by avoiding psdevtab files that are symlinks or have link counts
higher than 1, and by not looking for /tmp/psdevtab anymore, as
the reason for it to exist is really obsolete.

w -s output has been fixed.  Scripts that depend on w -s output
should be examined.  The output was broken enough to warrant this
change; it was extremely buggy.


NEWS for version 1.2.4 of procps

I_WANT_A_BROKEN_PS environment variable turns off usage warning.

"w <username>" sense corrected.

argument order problem fixed.

XConsole doesn't dump core on exit any more (only fclose if the
file is open...)

NEWS for version 1.2.3 of procps
