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.
|
||||
Included m_irixsgi.c from some source that's been floating around
|
||||
SGI. Don't yet know how it compares to m_irix62.
|
||||
|
||||
Fri Mar 10 2000 - wnl (3.5beta11)
|
||||
top.c: avoid potential loop if stdout gets closed, use macro
|
||||
for p_active to avoid collision with system macros.
|
||||
m_sunos5: widened some fields to accomodate 5.8.
|
||||
m_decosf1: added ordering support
|
||||
m_irix62_64: provides 64-bit module based on m_irix62.
|
||||
m_irix62: skip bogus files in /proc directory
|
||||
m_svr42MP and m_svr5: complete replacement with updated copies
|
||||
m_mtxinu: complete replacement with updated copies
|
||||
m_aix43: new module for 4.3
|
||||
getans: replaced with a Bourne shell script
|
||||
|
||||
Mon Mar 6 2000 - wnl (3.5beta10)
|
||||
m_sunos5.c: workaround for curses bug: ensure that TERMINFO has
|
||||
a value.
|
||||
|
||||
Fri Jan 15 1999 - wnl (3.5beta10)
|
||||
top.c: now check return code from read to avoid looping on eof.
|
||||
top.c: delay of 0 now only valid for root.
|
||||
decosf1.c: patches from Rainer Orth should fix most of the
|
||||
problems with this module (including the display of certain
|
||||
processes and runtime errors).
|
||||
sunos5.c: Rainer insisted on putting the slash back in the
|
||||
state field ("run/4") and widened the field to accomodate it.
|
||||
aix.c: widened PID field for 6-digit pids (shortened NICE field)
|
||||
module macosx added, thanks to Andrew Townley.
|
||||
|
||||
Fri Dec 18 1998 - wnl (3.5beta9)
|
||||
Configure checks status of "make" and complains if it fails.
|
||||
|
||||
Thu Dec 17 1998 - wnl (3.5beta9)
|
||||
Added module sco5 from Mike Hopkirk.
|
||||
Added module netbsd132 from moto kawasaki.
|
||||
|
||||
Sun Oct 25 1998 - wnl (3.5beta9)
|
||||
Added Casper's patches for sunos5 for the following:
|
||||
produce same results as swap -s (5.5 and higher),
|
||||
don't use system_pages kstat when /dev/kmem can be opened,
|
||||
skip . and .. when reading /proc, replace use of SOLARIS24
|
||||
with OSREV.
|
||||
|
||||
Fri Sep 11 1998 - wnl (3.5beta9)
|
||||
Added workaround to getans for the absence of $< in SCO Unix.
|
||||
|
||||
Wed Jul 1 1998 - wnl (3.5beta9)
|
||||
Changed structure member "errno" to "errnum" in commands.c.
|
||||
Replaced hpux10 module with one from John Haxby.
|
||||
|
||||
Fri Apr 17 1998 - wnl (3.5beta8)
|
||||
Moved definition of _KMEMUSER earlier in m_sunos5.c. This should
|
||||
fix the compilation problem with gnu 2.7.2.3, obviating the need
|
||||
for the fixinc.svr4 patch, but hopefully will not affect anything
|
||||
else.
|
||||
Added -DORDER to m_sunos4mp.c
|
||||
|
||||
Tue Nov 18 1997 - wnl (3.5beta7)
|
||||
Added gcc 2.7.2.3 patch for fixinc.svr4 and changed INSTALL and
|
||||
FAQ to refer to it.
|
||||
Added NetBSD HP9000 fix. Hopefully it doesn't break other
|
||||
NetBSD platforms.
|
||||
|
||||
Fri Oct 24 1997 - wnl (3.5beta7)
|
||||
Modified m_dcosx.c to change uses of procdir to xprocdir, avoiding
|
||||
a name clash with an include file (Bryn Parrott)
|
||||
|
||||
Sat Oct 11 1997 - wnl (3.5beta6)
|
||||
Incorporated Casper's patches for Solaris 2.6 and for the multi-
|
||||
processor bug ("kstat finds too many cpus").
|
||||
|
||||
Sun Jan 20 1996 - wnl (3.5beta5)
|
||||
Fixed Casper's m_sunos5 module: there was a poor interaction with
|
||||
his use of OSREV and SunOS 5.5.1.
|
||||
|
||||
Fri Dec 20 1996 - wnl (3.5beta4)
|
||||
Replaced m_sunos5 with a reworked version by Casper Dik. This one
|
||||
should work under 2.6 and may not require that top be run setuid
|
||||
to root under 2.5 or 2.6. This also fixed a bug in m_sunos5 that
|
||||
was introduced in beta3.
|
||||
Fixed calculation of OSREV in Configure.
|
||||
|
||||
Wed Nov 20 1996 - wnl (3.5beta3)
|
||||
Incorporated contributed fixes to: bsdos2, irix62, freebsd20,
|
||||
ultrix4, sunos5. Changed calculation of swap area in sunos5 (now
|
||||
uses swapctl). sunos5 now understands idled processors. Changed
|
||||
Configure to determine os revision using uname (when available)
|
||||
and adding it to machine.c compiliation in Makefile as -DOSREV.
|
||||
Changed calls to "exit" in modules to use "quit" instead.
|
||||
|
||||
Oct 20 1996 - wnl (3.5beta3)
|
||||
Removed "time" from list of ordering choices: there's no easy way
|
||||
to get cpu time for all processes (it's in the u area).
|
||||
|
||||
Fri Oct 18 1996 - wnl (3.5beta3)
|
||||
hpux10 and hpux9: using a better means for determining when a
|
||||
process is idle.
|
||||
decosf1 now includes utils.h.
|
||||
|
||||
Fri Sep 13 1996 - wnl (3.5beta2)
|
||||
Fixed Configure to build Make.desc in such a way that doesn't
|
||||
require a long argument to sed.
|
||||
|
||||
Thu Sep 12 1996 - wnl (3.5beta2)
|
||||
Fixed bug in display.c that affected empty cpustate names.
|
||||
Created hpux1010 module - a variant of hpux10 that does not use
|
||||
struct proc or struct user (suitable for HP/UX 10.10).
|
||||
|
||||
Wed Sep 11 1996 - wnl (3.5beta2)
|
||||
Changes to sunos5 module: Removed WCPU column since it is meaningless
|
||||
on a SVR4-based system. Added THR column to show number of threads
|
||||
for each process. This was not straightforward: the information is
|
||||
not stored in prpsinfo but rather in prstatus.
|
||||
|
||||
Tue Sep 10 1996 - wnl (3.5beta1)
|
||||
Added patches for sunos4mp to provide order support.
|
||||
Added irix62 module.
|
||||
Changed prime.c to include stdio.h for printf prototype.
|
||||
Added conditional code to os.h and utils.c to handle systems
|
||||
where sys_errlist is defined in stdio.h (such as NetBSD).
|
||||
|
||||
Mon Sep 09 1996 - wnl (3.5beta1)
|
||||
Removed tar and shar rules from Makefile.X -- don't need them anymore.
|
||||
Added -v option to display version number. Updated man page.
|
||||
|
||||
Thu Aug 29 1996 - wnl (3.4)
|
||||
Replaced modules (from Tim Pugh): next 32, next40.
|
||||
Fixed bug in username.c: hashing negative uids.

FREQUENTLY ASKED QUESTIONS AND THEIR ANSWERS
|
||||
@ -14,40 +15,57 @@ GENERAL
|
||||
|
||||
1. "Where do I get the latest version of top?"
|
||||
|
||||
The latest version of top is now available at the site "ftp.groupsys.com" in
|
||||
the directory "/pub/top". It is also available at "eecs.nwu.edu" in the
|
||||
directory "/pub/top".
|
||||
|
||||
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?"
|
||||
|
||||
Not at this time, but I am planning one. When it is finally available, you
|
||||
will be able to find it at "www.groupsys.com."
|
||||
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.
|
||||
|
||||
3. "Is there a mailing list for top?"
|
||||
|
||||
Currently 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.
|
||||
I am planning a general mailing list for announcements and such, but it is
|
||||
not yet available.
|
||||
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.
|
||||
|
||||
4. "How can I find out when all these things become available?"
|
||||
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. "What about Year 2000 compliance"?
|
||||
|
||||
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.
|
||||
|
||||
Information about the web site and the mailing list will be made available
|
||||
in future distributions of top. New distributions will be announced on the
|
||||
appropriate Usenet newsgroups (including comp.sources.unix).
|
||||
|
||||
5. "Why does it take so long for a new version of top to go through the
|
||||
beta test process?"
|
||||
|
||||
This is completely my fault. I have just not had the time recently 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.

Gnu CC likes very much to use its own include files. Not being a gcc

expert, I can't explain why it does this. But I can tell you that if you

upgrade your operating system (say from Solaris 2.4 to Solaris 2.5) after

installing gcc, then the include files that gcc uses will be incorrect,

rebuild and reinstall the "standard" include files for gcc (look for a

script in the distribution called "fixincludes"), (2) compile machine.c
|

with "CFLAGS=-I/usr/include" then make the rest of the object files

21. "When I try to run Configure, it complains about a syntax error."
|

Some versions of SCO's csh do not understand the syntax "$<". This breaks

Configure. You'll just have to hack around it for now: the Configure script
|
||||
is going to be completely redone in the near future anyway.

Some versions of SCO's csh do not understand the syntax "$<". Earlier

releases of top depended on this syntax to read input from the installer's

Top and the Year 2000
|
||||
|
||||
The software package top will not be affected by years numbering
|
||||
between 2000 and 2037. No portion of the top code stores dates on
|
||||
disk. All date processing in top is performed with functions from the
|
||||
Unix C library and Unix kernel. The specific functions are: time(2)
|
||||
and ctime(3S). These functions deal exclusively with conventional
|
||||
Unix time values (number of seconds since Midnight January 1, 1970
|
||||
GMT) and produce strings with a 4-digit year. At no point in the code
|
||||
for top are the last two digits used to represent a year.
|
||||
|
||||
Top and the Year 2038
|
||||
|
||||
In the year 2038 top will fail to represent the time of day correctly
|
||||
on 32-bit Unix operating systems. This is due to a limitation in the
|
||||
way Unix represents time. Top will only work on systems whose kernel
|
||||
call "time" and C library call "ctime" have been adjusted to represent
|
||||
time with a value greater than 32 bits. The exact date and time of
|
||||
this failure is 3:14:08 January 19, 2038 GMT. Note that this failure
|
||||
will only affect the display of the current time in the output from
|
||||
top.
|
||||
|
||||
|
||||
THERE IS ABSOLUTELY NO WARRANTY PROVIDED WITH THIS SOFTWARE.

||||
