+Tue May  6 2008 - wnl (3.8beta1)
+	Main code: fixed bugs in screen_cleareol and in display code. Fixed
+	bug in i_swap when all data is 0.  Added ^W patch (from thaquis).
+	Fixed bug in xdprintf.  Added command line options for the "t" and
+	"m" commands.
+	SunOS 5 changes:  Support for showing individual threads.  Redid
+	allocation of prpsinfo structures.  Added a pidthr hash that uses
+	both pid and thread id for a key. Changed format_process_header
+	and format_next_process to use a table-driven method for generating
+	the columns.  Status files from /proc (psinfo and lpsinfo) are now
+	cached to avoid repeatedly reopening them.  Column showing number of
+	LWPs is now called "NLWP" and column showing lwpid is "LWP".
+	FreeBSD changes: Runtime check to ensure binary is running on
+	the same machine type it was compiled for.  Lots of cleanup and
+	changed nearly everything to use sysctl rather than kvm, and
+	inability to open kvm is no longer fatal. Improved thread reporting:
+	disabled for 7.x and lower.  Added lwpid hash for proper tracking
+	of threads.  Changed format_process_header and format_next_process
+	to use a table-driven method for generating the columns.
+	Dec Alpha: configure uses compile-time options to properly trap
+	and handle exceptions from the Alpha FPU (from Brian Maly).
+
+Tue Feb 26 2008 - wnl (3.7)
+	Prepare for version 3.7 release.
+
+Fri Feb  1 2008 - wnl (3.7beta4)
+	Using the $ notation in printf formats for freebsd apparently was
+	causing problems on 64-bit systems. All such usage has been
+	removed and the process line is formatted piecemeal.
+
+Thu Dec 27 2007 - wnl (3.7beta3)
+	Improved function comments in display.c for message_error functions.
+	Changed some of the error messages in top.c to be more succint.
+
+Fri Dec  7 2007 - wnl (3.7beta3)
+	Changes to freebsd port: moved some functions up front to
+	eliminate forward references. Use sysctl to get all vm stats
+	information, as some of this isn't updated in the struct
+	vmmeter under FreeBSD 7.0.  Added routines to support large-scale
+	sysctl access.
+
+Wed Nov 28 2007 - wnl (3.7beta3)
+	Changes to documentation: FAQ, README, man page.
+
+Tue Nov 27 2007 - wnl (3.7beta3)
+	For freebsd, added page faults, pageins, pageouts, and pages
+	freed to the kernel display line.  These numbers reflect the
+	values presented in vmstat.  For sunos5, added page faults,
+	pageins and pageouts to the kernel display line.
+
+Fri Nov  2 2007 - wnl (3.7beta3)
+	Added copyright notices to the top of every source and include file.
+	Added copyright information to the man page.
+	Removed a few outdated things from the manifest.
+	Minor changes to sigconv.awk. 
+
+Sat Oct 27 2007 - wnl (3.7beta3)
+	Added check for sys_signame at configure time and if it is
+	present then it is used in commands.c to translate signal names
+	in to numbers.
+	Added alternate snprintf and vsnprintf functions from apache (in
+	ap_snprintf.c).  Added configure magic to define and compile them in
+	where needed.  Added check to configure for variadic macros.
+	Preprocessor defintion of dprintf (in utils.h) now depends on
+	support for variadic macros.  Cleaned up m_linux code.
+
+Wed Oct  3 2007 - wnl (3.7beta3)
+	Lots of changes, thanks to Mark Wong.  Most changes were to
+	clean the code up so that it would compile cleanly with -Wall
+	(all warnings).  Changed function names in screen.c so that
+	they all start with "screen_".  Isolated all interaction with
+	termcap to screen.c by adding a real function for cursor
+	addressing (in the past it was just a macro).  Only screen.c
+	now needs to worry about defining templates for the termcap
+	functions.  Added configure and preprocessor magic to ensure
+	that all the termcap functions used in the code are defined
+	with templates.  Changed names of some other functions and
+	global variables to avoid name conflicts with functions in
+	curses and other well established libraries.  Changed dprintf
+	macro to use variadic arguments so that the preprocessor can
+	gobble up the entire call when compiling without debugging
+	(this will have to be made more portable). All include files
+	are surrounded by #ifndef statements to accomodate multiple
+	inclusions.  Platform module is now compiled with
+	-fno-strict-aliasing as some of the modules do type punning
+	that can confuse the optimizer.
+
+Wed Sep 26 2007 - wnl (3.7beta3)
+	For freebsd, priority is no longer normalized by PZERO.  This
+	contradicts the behavior used by ps when it displays priority.
+	But normalizing by PZERO has become a bit of an anachronism
+	and it actually obscures the meaning of the priority without
+	adding any real value.
+
+Wed Sep 19 2007 - wnl (3.7beta3)
+	Many changes to improve the display of threads.  Changed
+	process summary line to use the word "threads" when showing
+	individual threads.  Added the system command to toggle the
+	display of system processes.  Fixed bug in hash.c remove_pos.
+	For freebsd: count threads correctly when they are being
+	displayed, nice column is more closely in line with ps
+	(nothing fancy for real time processes), add two more process
+	states that didn't exist in older releases of freebsd (wait
+	and lock).
+	For linux: Threads done right.  Now track individual threads
+	of multi-threaded processes separately so that we always know
+	their %cpu.  Switch to format_process_header so that we can
+	change the column headings and remove the THR column when
+	displaying individual threads.  Switched process (and thread)
+	tracking over to use generic hash table functions included
+	with the new version of top.  Process states and total now
+	include threads when they are being shown. Added "SHR" column
+	to show the amount of shared memory per process. Improved
+	calculation of elapsed time and percent cpu to avoid
+	overflows. Remove weighted cpu calculations entirely as it is
+	an anachronism.
+	For Solaris: Moved check for libelf to accomodate older systems.
+	
+Sun Sep  9 2007 - wnl (3.7beta2)
+	Documentation changes.  Fixes to sunos5 port.  Added display of
+	thread count and selection by command name to linux port.  Removed
+	the use of inline functions from hash.c as that doesn't appear to
+	be very portable.
+
+Wed Sep  5 2007 - wnl (3.7beta1)
+	Fixed freebsd and linux configuration bugs.  Added configuration
+	options for tweaking program defaults.  Rewrote top level code
+	(top.c) from scratch, including command handling so that adding
+	new commands is much easier.  Changed message-line handling to
+	ensure that the message is displayed for at least 5 seconds
+	regardless of the update frequency.  Added a "miniupdate" that
+	occurs one second after the initial screen on systems that don't
+	already delay the first screen.  The mini-update shows cpu state
+	percentages.  Added ability to select output by command name on
+	some systems.  Fixed color toggling via the "C" command.  Added
+	long options via getopt_long to complement the existing single
+	character options.  Added the freebsd "m" command to chose
+	alternate display modes.  On freebsd this gives a process i/o
+	display.  Added the freebsd "H" command to select the display of
+	individual threads.  Added "-a" option ("all") to set number of
+	displays and number of processes to infinity (equivalent to
+	"-d all all").  Added dual architecture compilation for Solaris
+	to generate both a 32-bit and a 64-bit binary.  This is on by
+	default when compiling on a 64-bit system and can be explicitly
+	set via "configure --enable-dualarch".  Added uniform hashing
+	functions that use bucket hash for uint, pid, and string.  Changed
+	username.c and the sunos and freebsd modules to use these functions.
+	Added the "kernel" information line to the display to show
+	statistics on what the kernel is doing (context switches, forks, 
+	traps, etc.).  This requires explicit support by the platform
+	module, currently only freebsd, linux, and sunos.
+
+Wed Apr 18 2007 - wnl (3.6.1)
+	Fixed a few bugs in sigconv.awk that were causing incorrect
+	results on FreeBSD.  Changed configure.ac to fix a few linux
+	problems: signal include file and /proc/1/stat.
+
+Fri Apr 13 2007 - wnl (3.6.1)
+	Removed the use of VPATH for compiling the system module and used
+	an explicit dependency in the Makefile instead.  VPATH is now set
+	to just srcdir to ensure that top will compile correctly when
+	configured from a different directory.  On systems without VPATH
+	support, top will still configure and compile, but only
+	from within the source directory.  This fixes bug 1699526.
+
+Fri Feb  2 2007 - wnl (3.6.1)
+	Revised the way that configure figures out owner, group, and mode.
+	For systems that don't use the kernel, it tries to match install
+	settings to allow access to stuff in /proc.  More importantly, if
+	mode is 755 then neither owner nor group are set.  This fixes bug
+	1631136.  Added patch from haanjdj@xs4all.nl to fix an occasional
+	core dump in m_decosf1.c.  This checks return code from task_threads.
+	Made sure all get_system_info functions are declared void.  Fixed
+	string termination bug.  Cleaned up documetation for sunos5.
+
+Tue Aug  8 2006 - wnl (3.6.1)
+	For Solaris, changed the tag "swap" to "total swap" to clarify
+	what is beign displayed.  Note that the calculations are still the
+	same: the display is just showing total rather than total - free.
+
+Thu Apr 27 2006 - wnl (3.6)
+	Added patches for linux-style sort shortcuts and for Unixware
+	support in configure (patch 1474427).  Fixed sunos5 to do slow start
+	and to ensure cpucount is set (patch 1477386).  Added pagination
+	routines to display.c and modified show_help to use it, since the
+	help screen is now longer than 24 lines.  Applied patch for unixware
+	support that adds check for mas library (patch #1474423).  Solaris
+	cpu percent now reflects a percentage of the entire server, rather
+	than a single cpu (bug 1478138).
+
+Mon Mar 27 2006 - wnl (3.6)
+	The production release of version 3.6.  Fixed a minor scaling
+	bug in the decosf1 module.  Support for MacOS X is officially
+	withdrawn although the macosx module is still part of the
+	distribution.  Hopefully this is a temporary situation.
+	Documentation updated.
+
+
+Wed Feb 15 2006 - wnl (3.6beta5)
+	Minor changes to eliminate warnings from the Sun Studio compiler.
+	These were mostly sloppy argument declarations.  I also added
+	message.h to provide an interface file for just the message
+	related functions of display.c.
+
+Mon Dec 26 2005 - wnl (3.6beta4)
+	Added new netbsd module, courtesy of Simon Burge.
+	Fixed a few bugs in SVR4 module and added its use to
+	configure.ac, thanks to Sanchet Dighe.  Also ensured that the
+	novpath Makefile was in the distribution.
+	Fixed portability problem in display.c
+
+
+Mon Oct 24 2005 - wnl (3.6beta3)
+	Set up a color tagging mechanism in color.c to allow for the
+	dynamic creation of tag names to contol color highlighting.
+	These names are partially derived from the tags used to label
+	memory and swap information on the screen, thus are driven by
+	the machine module itself.  Added -T option to list color 
+	highlighting information.  Help screen now includes the actual
+	list of sort order names.  Incorporated some minor fixes to
+	the main code from the Freebsd source tree.  Fixed bug #1324582.
+	Freebsd 5: removed WCPU column and added THR column.  Display
+	for freebsd 4 and earlier unchanged since they don't track
+	threads in the kernel.  Added LICENSE file to distribution.
+
+Wed Oct 12 2005 - wnl (3.6beta2)
+	Major overhaul to display.c.  All lines of the display are
+	directly tracked and controlled via display_write and its
+	companion display_fmt.  Added support for complete control
+	of ANSI color on the screen: this will be used in the future
+	to allow for full use of color everywhere on the screen.
+	Signal handling code now uses sigaction on all systems that
+	support it.  Restored the freebsd module and did away with
+	freebsd4, and upgraded freebsd module to support 5.x.
+	Fix bug #1306099 (wio(wait) timer ignored on OSF1).
+
+Fri Sep 23 2005 - wnl (3.6beta1)
+	Fixed bugs #1266341 (compilation errors with gcc 4.x),
+	#1156464 (cpu% field for sunos), #1156243 (compilation
+	errors on AIX).  Applied patches #1217855 (Solaris 10
+	xarch flag).  Overhaul of sunos5 module, making code more
+	efficient and easier to follow.  Got rid of need for MEMTYPE
+	type in utils.h.  Changed all memory statistics data in the
+	module specification from an int to a long to better support
+	64-bit systems with lots of memory. Moved all unused modules
+	out of the distribution (I will add them back in as needed).
+	Moved freebsd module to freebsd4 as it won't work with 5.x
+	(a new module will be necessary). Added support to configure
+	for makes that don't understand VPATH. Updated documentation:
+	man page, FAQ, README, INSTALL.
+
+Mon Jan 24 2005 - wnl (3.6alpha10)
+	Updated aix43 module with ANSI function declarations and fixed
+	declaration of get_system_info.  Configure now uses irixsgi
+	module for irix6* systems.  Updates to the following modules:
+	irixsgi, sunos5.  Fixed null pointer bug in color.c. Removed
+	some useless code and definitions in display.c
+
+
+Sun Nov 28 2004 - wnl (3.6alpha9)
+	Replace AIX 5 module with alternate (bug 1056565).
+	Fixed vulnerability in use of snprintf.
+
+Fri Oct 22 2004 - wnl (3.6alpha8)
+	Support for linux 2.6, added more stuff to memory and swap lines.
+	Updated linuxthr module, which is only useful on 2.4 and earlier.
+	Added some color support back in (feature request 930588), but
+	still need to add it back to the per-process display.  Added
+	OSF 5 support (untested).
+	Fixed bug 1017951 (invalid process count argument not caught)
+
+Tue Apr 20 2004 - wnl (3.6alpha7)
+	Added 64 bit support for AIX.
+
+Thu Apr 15 2004 - wnl (3.6alpha6)
+        Included fixes for decosf1 pid size and updated module.  Also
+        added osf1 to list of recognized operating systems in configure.ac.
+
+Tue Mar 30 2004 - wnl (3.6alpha5)
+	Minor bug fixes and some code rearrangement.  Changes to install
+	rule.  Added several more platforms including: aix 4.2 thru 5,
+	MacOS 10, Dec OSF, HPUX 7 thru 11.  Fixed the core dumping bug
+	in linux.  Code cleanup, including sigdesc.h (by changing
+	sigconv.awk).  Startup error messages are displayed on the
+	first screen rather than beforehand (no more pause).  Cleaned
+	up interrupt handling to avoid a race condition.  Eliminated
+	top.local.h.  REMOVED Configure!!!
+
+Mon Mar 22 2004 - wnl (3.6alpha1)
+	Now using gnu autoconf.  Eliminated the need for CFLAGS and LIBS
+	tags in the module source files.  Autoconf tries to figure all
+	that out now.  Machine module interface now uses flags to determine
+	if module supports sorting, selective display of idle processes,
+	viewing full commands.  Added display of uptime for modules that
+	support it.  Added display of full command lines for modules that
+	support it.  3.5 modules must be changed a bit to work for 3.6:
+	ORDER is no longer defined, and the module must fill in the
+	appropriate fields in struct statics to get the extra features.
+	Added a extenstion interface to allow for putting extra stuff
+	on the screen -- this is still half baked and not documented.
+
+Mon Feb 23 2004 - wnl (3.5)
+	Turned rc1 in to version 3.5.  Only changes were to the FAQ.
+
+Mon Feb  2 2004 - wnl (3.5rc1)
+	Changed format_k (utils.c) to use MEMTYPE for its parameter.
+	On most systems this is a long, but if the module defines 
+	USE_SIZE_T, this is set to be a size_t.  The sunos5 module
+	now defines it, so that it will work correctly on 64-bit
+	machines.  New "linuxthr" module for rolling up processes
+	that are really threads.  Configure autodetects when running
+	on a 64-bit Solaris machine.
+
+Tue Dec 16 2003 - wnl (3.5beta13)
+	Improved linux module.  For Solaris, changed "THR" column
+	heading to "LWP" since that's what they really are.
+
 Thu Mar 30 2000 - wnl (3.5beta12)
 	Updated modules: m_aix41.c, m_aix43.c, m_mtxinu.c, m_sco5.c,
 	and m_ultrix4.c.

-"LoadMax", then top will put the cursor home immediately after the space
-is pressed before the next update is attempted.  This serves as a visual
-acknowledgement of the command.  "LoadMax" should always be specified as a

+                    Frequently Asked Questions and their Answers
 
-FREQUENTLY ASKED QUESTIONS AND THEIR ANSWERS
 
-This FAQ is broken out in to several topics.
 
+     GENERAL
 
-GENERAL
+ 1.  What is top? 
 
- 1.  "Where do I get the latest version of top?"
+     Top provies the user with a regularly updated display showing
+     information about the system and its top cpu-using processes. Think
+     of it as a full-screen "ps" output that gets updated at regular
+     intervals.
 
-The official site for top is "ftp.groupsys.com" in the directory
-"/pub/top".  It is also available from the following mirror sites:
-"pharos.dgim.doc.ca" in /packages/top, "uiarchive.uiuc.edu" in
-/pub/packages/top, "sunsite.auc.dk" in /pub/unix/top.  European
-users should consider using the Denmark (dk) site.
- 
- 2.  "Is there a web page for top?"
+ 2.  Where do I get the latest version of top? 
 
-Yes.  Point your browser at http://www.groupsys.com/top.  It includes
-all documentation, a nice interactive display which describes the
-various components of the output of top, web-based retrieval of the
-package, year 2000 information, and pointers to the mailing list.
+     The official site for top is "ftp.unixtop.org" in the directory
+     "/pub/top". Top is also a SourceForge project, and the most recent
+     releases are available on any of the SourceForge mirrors. The
+     SourceForge project page is at
+     http://sourceforge.net/projects/unixtop.
 
- 3.  "Is there a mailing list for top?"
+ 3.  Is there a web page for top? 
 
-The official list for announcements is "top-announce@groupsys.com".
-This list is managed by "majordomo@groupsys.com".  Announcements of
-importance to all top users will be sent to this list, including new
-releases, availability of beta test versions, emergency revisions and
-patches, etc.  Anyone is welcome to join top-announce.  This is a
-read-only list.  The list of subscribers will not (intentionally) be
-made available, and postings to the list are limited.
+     Yes. Point your browser at http://www.unixtop.org. It includes all
+     documentation, a nice interactive display which describes the various
+     components of the output of top, web-based retrieval of the package,
+     year 2000 information, and other neat stuff.
 
-In addition, there is a top developers mailing list that is used by
-beta testers and other people who help me port the program to various
-machines.  Membership to this list is solely at my discretion.  If you
-feel qualified to act as a beta tester, or if you are doing development
-work on top (such as porting to a new platform), you may submit a
-request by sending a message to "top-spinners-request@groupsys.com"
-containing the word "subscribe".  I will contact you within a few days,
-as my schedule permits.
+ 4.  Is there a mailing list or on-line bulletin board for top? 
 
- 4.  "What about Year 2000 compliance"?
+     There is a mailing list used for general announcements regarding top,
+     including new releases. This mailing list is available to sourceforge
+     members and can be accessed from the unixtop sourceforge project
+     page. Visit SourceForge and search for the project "unixtop", then
+     click on "mailing lists". There are also on-line forums available
+     through SourceForge where members can post questions and comments.
 
-Top should not experience any problems with the transition to the year
-2000.  A full statement concerning top and the year 2000 can be found
-in the file "Y2K" included with the distribution.
+ 5.  What about Year 2000 compliance? 
 
+     Top did not experience any problems with the transition to the year
+     2000. A full statement concerning top and the year 2000 can be found
+     in the file "Y2K" included with the distribution.
 
- 5.  "Why does it take so long for a new version of top to go through the
-      beta test process?"
+ 6.  Will there be another major release of top? Will there be a top
+     version 4? 
 
-This is completely my fault.  I have just not had the time to give top
-the attention it deserves.  I thank everyone for their patience, and I
-hope that with the recent changes in the direction of my career that I
-can spend more time on this.
+     I have some great ideas for the next major release of top, and I very
+     much want to make those ideas a reality. What I don't have much of
+     these days is free time. But I will keep poking at it and I hope to
+     have top version 4.0 ready by the fall of 2006.
 
- 6.  "Top is not written in ANSI C.  Do you ever plan to change that?"
+ 7.  Does top really support multi-processor systems? 
 
-Top predates ANSI C by about 5 years.  Yeah, it'll get "fixed" eventually.  
-Probably in 3.6.
+     On platforms that support multiple processors, top is able to detect
+     and correctly summarize the information about those processors. What
+     top does not do is break down the cpu states summary (the third line
+     of the display) by cpu. Instead it collects the cpu state information
+     from all processors and combines them in to a single line. Some
+     vendors  include a modified version of top that presents this
+     information for each cpu. Top 3.7 may have this functionality but it
+     is not present in the standard top 3.6 release.
 
+ 8.  Is top under CVS control? Can I access the sources via SourceForge
+     CVS or Subversion? 
 
-CONFIGURING
+     I maintain top using subversion, not CVS. Although I utilize my own
+     private subversion repository, it is regularly mirrored in to the
+     SourceForge Subversion repository. You can access the SourceForge
+     repository here: https://svn.unixtop.org/unixtop/top-3.
 
- 7.  "Configure said that it saw /proc and is recommending that I install top
-      setuid root.  Is there any way around this?  Is it safe?"
 
-There is no way around it.  Complain to POSIX.  Every effort has been   made 
-to make top a secure setuid program.  However, we cannot guarantee that 
-there are no security problems associated with this configuration.  The 
-places where top is most vulnerable are the builtin kill and renice 
-commands.  There is no internal top command that causes top to start a shell 
-as a subprocess.  Some SVR4 systems may contain a bug that enables a user to 
-renice his own processes downward (to lower nice values that are more 
-favorable for the process).  This problem has been fixed for the Solaris 2.x 
-modules, but may still exist in others.  We will hopefully fix this up in 
-the next release.
+     COMPILING
 
- 8.  "Why is Configure a c-shell script?  I thought c-shell scripts were 
-      evil?"
+ 9.  We just upgraded our operating system to a new version and top broke.
+     What should we do? 
 
-They are.  :-)  I'll probably be rewriting the Configure script for the
-next release, or switching to something like Gnu configure.
+     Recompile it. Top is very sensitive to changes in internal kernel
+     data structures. It is not uncommon for a new version of the
+     operating system to include changes to kernel data structures.
 
 
-COMPILING
+     RUNNING
 
- 9.  "We just upgraded our operating system to a new version and top broke.  
-      What should we do?"
+10.  I just finished compiling top and it works fine for root, but when I
+     try to run it as a regular user it either complains about files it
+     can't open or it doesn't display all the information it should. Did I
+     do something wrong? 
 
-Recompile it.  Top is very sensitive to changes in internal kernel data 
-structures.  It is not uncommon for a new version of the operating system to 
-include changes to kernel data structures.
+     Well, you're just not done. On many operating systems today, access
+     to many of the kernel memory devices and other system files is
+     restricted to either root or a particular group. The configure script
+     figures this out (usually) and makes sure that the "install" rule in
+     the Makefile will install top so that anyone can run it successfully.
+     However, you have to *install* it first. Do this with the command
+     "make install".
 
+11.  Top is (not) displaying idle processes and I don't (do) want it to. 
 
-RUNNING
+     This default has only changed about a dozen times, and I finally got
+     tired of people whining about it. Go read the manual page for the
+     current version and pay special attention to the description of the
+     "TOP" environment variable.
 
-10.  "I just finished compiling top and it works fine for root, but when
-      I try to run it as a regular user it either complains about files
-      it can't open or it doesn't display all the information it should.
-      Did I do something wrong?"
+12.  We have so much memory in our machine that the memory status display
+     (the fourth line) ends up being longer than 80 characters. This
+     completely messes up top's output. Is there a patch? 
 
-Well, you're just not done.  On many operating systems today, access to
-many of the kernel memory devices and other system files is restricted to
-either root or a particular group.  The Configure script figures this out
-(usually) and makes sure that the "intsall" rule in the Makefile will
-install top so that anyone can run it successfully.  However, you have to

+     Most modules have been changed to use new memory formatting functions

+     FREEBSD PROBLEMS
 
-14.  "The cpu state percentages are all wrong, indicating that my machine is 
-      using 95% system time when it is clearly idle.  What's wrong?"
+15.  This version of top does not show individual threads with the "t" or
+     "H" commands. Instead it says "command not available." Why? 
 
-This can happen if you compiled with gcc using the wrong include files.
-See the previous question.
+     Previous versions of top attempted to support the display of
+     individual threads under FreeBSD through the use of the "t" command.
+     However,  the FreeBSD kernel does not supply sufficient or correct
+     information on the individual threads within a process. So the data
+     that was being displayed was incorrect and misleading. Therefore, top
+     version 3.8 disables the use of this command to prevent the display
+     of incorrect information. FreeBSD 8.0 will correctly report
+     per-thread information and top version 3.8 supports the use of the
+     "t" command for version 8.0.
 
+16.  The "f" command (to display full command lines for the processes)
+     does not work and instead says "command not available". Why? 
+
+     The current version of top is able to use sysctl to retrieve almost
+     all of the information it needs without having to open /dev/kmem. The
+     one piece of information not available via sysctl is the full command
+     line of each argument. If you run top as a regular user and it cannot
+     open /dev/kmem (in other words, it is not installed set-gid to the
+     kmem group) then it will disable the "f" command. Make sure the top
+     binary is installed with a group ownership of "kmem" and with the
+     set-gid bit on if you want the "f" command to work properly.
+
+
+     MACOSX PROBLEMS
+
+17.  I tried to configure top on my Mac OSX system and I got an error
+     claiming "macosx not supported". What up? 
+
+     Since I don't have full time root access to a Mac OSX system I cannot
+     provide effective support for the platform. MacOSX uses Mach, and it
+     is very difficult to extract accurate system and process information
+     from the system. It takes a lot of trial and error, along with root
+     access. I have included the most up-to-date version of the macosx
+     module in the distribution, but I do not claim that it works. If you
+     want to try to use it, you can configure with "./configure
+     --with-module=macosx".
+
+
+     SUNOS PROBLEMS
+
+18.  I tried compiling top under SunOS version 4.1.x and it got compile
+     time errors or run time errors. Is there a patch? 
+
+     If you try compiling top in a "System V environment" under SunOS
+     (that is, /usr/5bin is before /usr/bin on your path) then the
+     compilation may fail. This is mostly due to the fact that top thinks
+     its being compiled on a System V machine when it really isn't. The
+     only solution is to put /usr/bin and /usr/ucb before /usr/5bin on
+     your path and try again.
+
+
+     SOLARIS PROBLEMS
+
+
+     NOTE: the most common source of problems with top under Solaris is
+     the result of compiling it with the wrong front end. Make sure that
+     /usr/ucb is not on your path before attempting to compile top under
+     Solaris.
+
+19.  Is there somewhere I can get a pre-compiled package? 
+
+     Yes. Although I don't provide pre-compiled binaries, you can get a
+     Sun-style package from www.sunfreeware.com.
+
+20.  Under Solaris 2, when I type "make", the system says "language
+     optional software package not installed." What's going on? 
+
+     You tried to compile with /usr/ucb/cc. Make sure /usr/ucb is not on
+     your path. Furthermore, you do not have a Sun compiler installed on
+     your system. You need a compiler to make top. Either Sun's C compiler
+     or the Gnu C compiler will work fine.
+
+21.  Under Solaris 2, when I run top as root it only shows root processes,
+     or it only shows processes with a PID less than 1000. It refuses to
+     show anything else. What do I do? 
+
+     You probably compiled it with /usr/ucb/cc instead of the real C
+     compiler. /usr/ucb/cc is a cc front end that compiles programs in BSD
+     source-level compatability mode. You do not want that. Make sure that
+     /usr/ucb is not on your path and try compiling top again.
+
+22.  Under Solaris 2, I compiled top using what I am sure is the correct
+     compiler but when I try to run it it complains about missing dynamic
+     libraries. What is wrong? 
+
+     Check to see if you have LD_LIBRARY_PATH defined in your shell. If
+     you do, make sure that /usr/ucblib is not on the path anywhere. Then
+     try compiling top again.
+
+23.  Under Solaris 2, when I try to run top it complains that it can't
+     open the library "libucb.so.1". So I changed the LIBS line in
+     m_sunos5.c to include -R/usr/ucblib to make sure that the dynamic
+     linker will look there when top runs. I figured this was just an
+     oversight. Was I right? 
+
+     No, you were not right. As distributed, top requires no alterations
+     for successful compilation and operations under any release of
+     Solaris 2. You probably compiled top with /usr/ucb/cc instead of the
+     real C compiler. See FAQ 22 for more details.
+
+24.  On my 64-bit system some processes show up with incorrect information
+     (such as zero memory). 
+
+     If you are running a 64-bit system, then you need to make sure that
+     you are running the 64-bit top binary. Top's configure script
+     attempts to detect 64-bit systems, and will automatically generate
+     both 32-bit and 64-bit binaries on such systems. If you use or
+     install the 32-bit binary on a 64-bit system top will still run but
+     will not produce the correct results. This will also happen if you
+     configure your distribution on a 32-bit system then compile with that
+     configuration on a 64-bit system. You must configure and compile on
+     the same system. For Sparc systems the 32-bit binary will be created
+     in the subdirectory "sparcv7" and the 64-bit binary will be created
+     in the subdirectory "sparcv9". For Intel systems the directories will
+     be "i386" (32-bit) and "amd64" (64-bit). In all cases a copy of 
+     /usr/lib/isaexec is made in the main directory and called "top". This
+     program will choose the correct binary to run from one of these
+     subdirectories. See isaexec(3c) for more details.
+
+25.  Can I install both 32-bit and 64-bit binaries on a central file
+     server and have machines which mount it automatically use the correct
+     one? 
+
+     Yes. If you configure and compile on a 64-bit system, top's configure
+     script and makefile will automatically create both 32-bit and 64-bit
+     binaries. The "install" rule in the makefile will install these
+     binaries in subdirectories of /usr/local/bin appropriate to the
+     architecture (sparcv7/sparcv9 or i386/amd64) then create a copy of
+     /usr/lib/isaexec named "top" in /usr/local/bin to ensure that the
+     appropriate is run when a user types "top". If you make sure that you
+     configure and compile on a 64-bit system, then "make install" will do
+     the right thing.
+
+26.  This version of top show less available swap space than previous
+     versions. Why does it no longer match the output of the swap summary
+     produced with "swap -s"? 
+
+     Starting with version 3.6 of top, the amount of swap space reported
+     by top has been changed to reflect only disk-based swap space. The 
+     swap summary produced with "swap -s" also includes memory-based swap
+     space. This changed was made for several reasons. It makes the
+     display under Solaris more like those of other operating systems. The
+     display is more what users expect (except those used to previous
+     versions of top). Most importantly, "swap -s" gets its data via an
+     undocumented system interface. Now that top no longer displays that
+     data it can use publically documented and maintained system
+     interfaces to retrieve its data.
+
+
+     SVR4-DERIVED PROBLEMS
+
+27.  When I run top on my SVR4-derived operating system, it displays all
+     the system information at the top but does not display any process
+     information (or only displays process information for my own
+     processes). Yet when I run it as root, everything works fine. What's
+     wrong? 
+
+     Your system probably uses the pseudo file system "/proc", which is by
+     default only accessible by root. Top needs to be installed setuid
+     root on such systems if it is going to function correctly for normal
+     users.
+
+
+     SVR42 PROBLEMS
+
+28.  The memory display doesn't work right. Why? 
+
+     This is a known bug with the svr42 module. The problem has been
+     traced down to a potential bug in the "mem" driver. The author of the
+     svr42 module is working on a fix.
+
+
+     STILL STUCK
+
+29.  I'm still stuck. To whom do I report problems with top? 
+
+     The most common problems are caused by top's sensitivity to internal
+     kernel data structures. So make sure that you are using the right
+     include files, and make sure that you test out top on the same
+     machine where you compiled it. Sun's BSD Source Compatability Mode is
+     also a common culprit. Make sure you aren't using either /usr/ucb/cc
+     or any of the libraries in /usr/ucblib. Finally, make sure you are
+     using the correct module. If there does not appear to be one
+     appropriate for your computer, then top probably will not work on
+     your system.
+
+     If after reading all of this file and checking everything you can you
+     are still stuck, then please use SourceForge to submit a support
+     request or a bug. Top is supported by the SourceForge project  named
+     "unixtop". On SourceForge you will find defect tracking, a mailing
+     list, and on-line forums. You can also contact the author through
+     SourceForge.

 INSTALLATION
 
-Configuration and installation of top is very straightforward.  After
-unpacking the sources, run the script "Configure".  It will present you
-with a series of questions, all of which should be explained in the
-presentation.  After you have answered all the questions, "Configure" will
-perform all the necessary configuration.  Once this is finished, type
-"make install".  Make will compile the sources then install the resulting
-executable and manual page in the appropriate places.
+Configuration and installation of top is easy.  Top version 3.6
+comes with a configure script generated by gnu autoconf.  After
+unpacking the tar file, simply run "./configure".  The script will
+automatically perform a series of checks on the system and determine
+what settings are appropriate for the Makefile and certain include
+files.  Once configure completes, simply type "make install" and
+top will be compiled and installed.  By default, the installation
+location is /usr/local/bin.  You can change the destination location
+with the --prefix option to configure.
 
-The most difficult step in the configuration is the choice of an
-appropriate machine-specific module.  The Configure script gives you a
-list of choices complete with brief descriptions of when each choice is
-appropriate.  Each module is contained in a separate c file in the
-directory "machine".  The module contains all of the machine-specific code
-that makes top work correctly on the architecture in question.  All of the
-code in the top-level directory is machine-independent (or at least
-strives to be).  Hints for some module choices that are not obvious are
-given at the end of this file.
+In addition to the standard options, top's configure script supports
+the following:
 
-The first comment in each c file in that directory contains the synopsis
-AND a detailed description of the machines for which that module is
-appropriate.  It also contains a list of authors for that module.  If you
-are really stumped in this choice, use grep to find your machine
-manufacturer's name or operating system name in machine/*.c.  If you still
-can't find one that is appropriate, then chances are very good that one
-hasn't been written yet.  If that is the case, then you are out of luck.
+    --with-module=name
 
-HANDLING MULTIPLE ARCHITECTURES
+	Force the use of a particular module.  Modules are located
+	in the subdirectory "machine".  A module's name is derived
+	from the file's basename without the leading "m_".
 
-If you need to recompile top for a different architecture (that is, using
-a different module) you need to reconfigure top.  A short cut is available
-to make this a little easier.  If all of your previous answers to the
-configuration questions (except for the module name of course) are
-adequate for the new architecture, then you can just use the command
-"Configure <modulename>".  The configuration script will reconfigure top
-using the new module and all the answers you gave last time.  It will
-finish with a "make clean".  Once that completes, type "make install"
-and make will compile the sources and do the installation.
+    --with-ext=name
 
-HANDLING MULTIPLE OS VERSIONS
+	Compile with the extension "name", found in the subdirectory
+	"ext". At the present time, there are no extensions in the
+	standard distribution.
 
-By far the most frequently received bug report for top is something like
-this: "We just upgraded our operating system to version 99.9.9.9 and top
-broke.  What should we do?"  The simple answer is "recompile".
+    --enable-debug
+    --disable-debug
 
-Top is very sensitive to changes in internal kernel data structures
-(especially the proc and user structures).  Some operating systems
-(especially SunOS) are notorious for changing these structure in every
-minor release of the OS.  This means that a top executable made under one
-version of the OS will not always work correctly (if even at all) under
-another version.  This is just one of those tough facts of life.  There is
-really no way around it.
+	Default off. Include debugging output in the compilation,
+	which can be seen with the -D switch.
 
-To make life even worse, some operating systems (SunOS again) will use
-slightly different proc and user structures on different models.  For
-example, "top" built on a SparcStation 2 will not run correctly on a
-SparcStation 10, even if they are both running SunOS 4.1.3.  These
-unfortunate circumstances make maintaining top very difficult, especially
-in an environment that runs several different versions of the same
-operating system.
+    --enable-color
+    --disable-color
 
-But there is hope.  If your operating system has a properly functioning
-"uname" command then you can handle this problem rather gracefully.
-Included in the distribution is a shell file called "metatop".  All this
-shell file does is:
+	Default on.  Include code that allows for the use of color
+	in the output display.  Use --disable-color if you do not
+	want this feature compiled in to the code.  The configure
+	script also recognizes the spelling "colour".
 
-	exec top-`uname -m`-`uname -r` "$@"
-
-So when you run this script, it execs a filename that is unique to your
-specific machine architecture and your OS revision number.
-
-To use "metatop", do the following:
-
-	. on any machine, run Configure and choose the module that is
-	  appropriate for the machine
-	. for all machines which use the same module:
-	    . group machines according to machine architecture AND OS
-	      revision number (i.e.: sun4-4.1.1, sun4c-4.1.1, sun4c-4.1.2,
-	      sun4-4.1.3, sun4c-4.1.3, sun4m-4.1.3, ...)
-	    . for each group, choose one machine from that group and on it
-	      run "make clean; make installmeta".
-
-
-The "installmeta" rule in the makefile will insure that top is compiled,
-install the shell file "metatop" as "top", then install the executable
-"top" with a name appropriate to the machine architecture and OS revision.
-
-
-HINTS FOR CHOOSING THE CORRECT MODULE:
-
-SOLARIS 2.x
-
-All versions of Solaris will now work with the module sunos5.  Version
-specific modules (such as sunos54) no longer exist.
-
-
-SUNOS 4.x AND MULTIPROCESSOR ARCHITECTURES
-
-First, we need to be speaking the same language:
-
-sun4	a regular sparc sun 4 architecture machine (sparc station 1,
-	sparc station 2, IPC, SLC, etc.)
-
-sun4m	a multiprocessor sparc (Sparc 10, 4/670, 4/690)
-
-I intended to write the sunos4 module so that an executable compiled on a
-sun4m machine would work correctly on a sun4 machine.  Unfortunately my
-experiments indicate that this cannot be done.  It turns out that the user
-structure is so different between these two architectures that nothing
-short of a serious hack will make the same executable work correctly on
-both machines.  I recommend that you use the separate module "sunos4mp"
-when making an executable for a sun4m architecture, and use "sunos4" when
-making an executable for sun4 or sun4c architectures.

-DIGITAL UNIX V4.0
-
-This is the successor to DECOSF/1.  Use the module decosf1.
-
-SOLBOURNE OPERATING SYSTEM (OS/MP)
-
-If you are running OS/MP version 4.1A, then use the module "osmp4.1a".
-
-If you are running a version of OS/MP OLDER than 4.1A (that is, one
-of its predecessors), use the module "sunos4".
-
-If you are running OS/MP 4.1B or LATER, use the module "sunos4mp".
-
-HP/UX OPERATING SYSTEM
-
-The module hpux8 works on all version 8 systems.  Some say that it works
-with version 9 as well, but one user did send me a separate module for
-version 9.  This module has only been tested on series 800 machines.  I
-would recommend the following for those running version 9: try hpux9 and
-if it doesn't work then try hpux8.  If neither work, then send mail to me
-and/or the modules' authors.  Another note:  we have a model 730 supposedly
-running version 9.01.  The module hpux9 did not compile successfully, but
-the module hpux8 worked fine.  The module hpux10 works on all revisions of
-HP/UX 10 except 10.10, where HP removed the definition of the proc structure
-from the system include files.
-
-NET/2 386BSD SYSTEMS
-
-If your version of the operating system has patchkit 2.4 installed,
-then you will need to modify machine/m_386bsd.c and uncomment the
-definition of PATCHED_KVM.  This patchkit makes what more than a few
-people believe to be a wholly unnecessary patch to the way the kvm
-routines work.
-
-A/UX SYSTEMS
-
-There is a module for A/UX 3.0 and 3.1.  Whether or not it works for
-any other version is not known.  Proceed at your own risk.
-
-Although AUX does not generally have a renice systemcall, it can be
-implemented by tweeking kernel memory.  The flag IMPLEMENT_SETPRIORITY
-controls the inclusion of this code.  It is off be default.  While
-such a simple hack should not be difficult to get right, USE THIS
-FEATURE AT YOUR OWN RISK!
+    --enable-kill
+    --disable-kill
 
+	Default on.  Include code that allows for renicing and sending

@@ -163,3 +161,69 @@ change in one of the existing files, please contact me so that we can
 discuss the details.  I want to keep such changes as general as
 possible.
 
+--------
+
+Changes were made to the module interface between 3.5 and 3.6.  Here are
+the changes that need to be made to port a 3.5 module to 3.6:
+
+The array that stores memory statistics and is passed back in the system
+information structure as "memory" must now be an array of (signed) longs.
+This was done to more easily accomodate systems that have gigabytes of
+memory.  Since the numbers are supposed to be kilobytes, a long can still
+represent up to 2 terabytes.  Look for "int memory_stats[X]" (where "X"
+is some arbitrary number) and change it to "long memory_stats[X]".  If
+the module support reporting swap information on a separate line, then
+its "swap_stats" array also needs to be an array of longs.
+
+The argument to proc_owner should be an int, as in "int pid".  When it is
+used in proc_owner it should be cast as necessary.  Many operating systems
+will require it to be cast to a pid_t before being compared to the appropriate
+element in the proc structure.
+
+In the function format_next_process, the last argument in the main call
+to sprintf is the string that contains the command for the process.
+Make sure that this last argument is enclosed in a call to "printable".
+For example:  "printable(MPP(pp, p_comm))".
+
+The third argument to "get_process_info" needs to be changed to an integer,
+typically "int compare_index".  The call to qsort in get_process_info may
+be guarded by "if (compare != NULL)".  If it is, remove the if statement.
+
+The other changes to get_process_info depends on whether or not the module
+supports multiple sort orders.
+
+To support multiple keys:
+
+Create an array int (*proc_compares[])() and assign to it the list of
+comparison functions, NULL terminated.  For example:
+
+int (*proc_compares[])() = {
+    compare_cpu,
+    compare_size,
+    compare_res,
+    compare_time,
+    NULL };
+
+In get_process_info there is a call to qsort which uses one of the
+functions in proc_compares.  It should be changed so that its fourth
+argument is "proc_compares[compare_index]".
+
+If the module contains the function "proc_compare", it should be removed.
+
+There should also be a NULL-terminated array of strings which list the names
+for the sort keys, for example:
+
+char *ordernames[] = 
+{"cpu", "size", "res", "time", NULL};
+
+To indicate that this module supports multiple sort keys, add the following
+line in machine_init:
+
+	statics->order_names = ordernames;
+
+If there is no support for multiple keys:
+
+Leave statics->order_names alone and call the comparison function of
+your choice in get_process_info, ignoring the third argument.

 reorganized in a major way to make it easy to port to other platforms.
 All system dependent code is now contained in one file.
 
-Top now includes a configuration script called "Configure".  It helps
-the installer choose the correct parameters for this particular
-installation.  This script MUST be run before attempting to compile top.
-
-Top requires read access to the memory files "/dev/kmem" and "/dev/mem"
-as well as the system image "/vmunix".  Some installations have these
-files protected from general access.  These sites would have to install
-this program in the same way that programs such as "ps" are installed.
-In addition, on those Unix variants that support the proc filesystem
-(such as SVR4 and Solaris 2), top requires read access to all the files
-in /proc: typically dictating that top be installed setuid to root.
+Starting with version 3.6, top includes a "configure" script generated
+by Gnu's autoconf.  This script MUST be run before attempting to
+compile top.  It will explore the system and generate approriate
+contents for Makefile, config.h, and top.1.
+
+On some systems, top requires read access to the memory files
+"/dev/kmem" and "/dev/mem" as well as the system's kernel image.  Most
+installations have these files protected from general access.  These
+sites would have to install this program in the same way that programs
+such as "ps" are installed.  On most systems with a /proc file system,
+top will try to read everything it can from /proc, but may need extra
+permissions to do so.  The configure script will determine the
+permissions needed by the top binary, and a "make install" as root
+will get the binary installed correctly.  Sometimes this requires that
+the binary be installed with set-group-id privileges and, in rare
+cases, set-user-id to root.
 
 CAVEAT: version 3 of top has internal commands that kill and renice
 processes.  Although I have taken steps to insure that top makes
 appropriate checks with these commands, I cannot guarantee that these
-internal commands are totally secure.  IF YOU INSTALL top as a SETUID
-program, you do so AT YOUR OWN RISK!  I realize that some operating
-systems will require top to run setuid, and I will do everything I can
-to make sure that top is a secure setuid program.
-
-Configure will ask you to input values for certain parameters.  Before
-each parameter, Configure will display a description of what the
-parameter does.  Read the description and choose an appropriate value.
-Sometimes a default will appear in brackets.  Typing just return will
-choose the default.
-
-System support now takes the form of "modules".  Adding support for
-a different architecture requires only adding a module.  Configure
-asks which module to use when it is configuring top.  See the file
-"Porting" for a description of how to write your own module.

+System support now takes the form of "modules".  Adding support for a

+are contained in the subdirectory "machine".  The "configure" script
+automatically determines which module is approproate.  However, it may
+not be able to determine what the correct module is.  This can happen
+either because it doesn't know about the system or there is no module
+to support the system.  In the former case, if you know which module
+to use, you can force "configure" to choose a particular module with
+the option "--with-module".  For example, if you want to force the use
+of the svr4 module (which appears as "machine/m_svr4.c") then use
+"configure --with-module=svr4" to generate the correct Makefile.  See
+the file "Porting" for a description of how to write your own module.
 
 To compile and install "top", read the file "INSTALL" and follow the
 directions and advice contained therein.
 
-Once you have created a binary for one particular type of machine, you
-can reconfigure for another type with "./Configure modulename" where

+Version 3.6 incorporated the idea of using ANSI color sequences to
+enhance information on the screen.  By default, no color is used.  But
+you can configure the use of color through the environment variable
+TOPCOLORS (or, for compatibility, TOPCOLOURS).  The interface is
+identical to the one first implemented by chris@spang.uk.eu.org, but

+to diable the feature entirely.

+Any information at the top of the screen can be enhanced with color.
+However, due to implementation difficulties, the per-process area
+cannot be color-enhanced.  A complete description of color support can
+be found in the man page.  References for ANSI color codes can be
+found all over the Internet, but if you want a handy reference, look

-is tickled by the decosf1 module when compiled under V3.0 (and perhaps
-earlier versions).  Top compiled using DEC's compiler with optimization
-will consistently produce a segmentation fault (in format_next_process

+ * "tag" is the name of the value to display with color.
+ *

+\`configure' configures top 3.8beta1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR           user executables [EPREFIX/bin]
+  --sbindir=DIR          system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR       program executables [EPREFIX/libexec]

+  --includedir=DIR       C header files [PREFIX/include]
+  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
+  --datarootdir=DIR      read-only arch.-independent data root [PREFIX/share]

+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
