1b9d0472b7
the src/contrib/top part right now). This tools is simply too system- dependant to maintain it in the ports collection.

Thu Aug 29 1996 - wnl (3.4)
|
|
Replaced modules (from Tim Pugh): next 32, next40.
|
|
Fixed bug in username.c: hashing negative uids.
|
|
|
|
Thu Aug 22 1996 - wnl (3.4beta3)
|
|
Patched modules: ultrix4, sunos4, sunos5, utek, decosf1, irix5.
|
|
Added modules: next40, next32.
|
|
Fixed procstates update bug in display.c.
|
|
Fixed divide by zero bug in utils.c.
|
|
Fixed bad number in layout.h
|
|
Minor fixes to Configure.
|
|
Complete overhaul of FAQ.
|
|
|
|
Tue Feb 13 1996 - wnl (3.4beta3)
|
|
Added convex module from Warren Vosper (originally written by
|
|
William Jones).
|
|
|
|
Tue Feb 13 1996 - wnl (3.4beta2)
|
|
Fixed format_k in utils.c to calculate K and M values correctly.
|
|
Added check for gigabyte values ('G'). Changed sumamry_format
|
|
in display.c to use format_k where appropriate.
|
|
Changed creation of distribution tar file to place everything in
|
|
a top level directory.
|
|
|
|
Tue Jan 30 1996 - wnl (3.4beta2)
|
|
Added m_aix41 module. Added new tag type to module comments:
|
|
TERMCAP, which defined the library to use for a termcap library.
|
|
If no TERMCAP tag is found in the module's initial comment, then
|
|
Configure will default to "-ltermcap". AIX needs this since it
|
|
put all the termcap routines in libcurses(!)
|
|
|
|
Added m_bsdos2 (found lingering in my mailbox).
|
|
Updated m_svr4 to include support for NCR multiprocessors.
|
|
Fixed small bug in utils.c
|
|
|
|
Thu Jan 25 1996 - wnl (3.4beta1)
|
|
Fixed m_sunos5 invocation of gettimeofday to include "NULL" as
|
|
second argument. This provides compatability with the Posix-
|
|
compliant template provided with SunOS 5.5, but doesn't hurt
|
|
previous versions since they do bother with a template for that
|
|
function.
|
|
|
|
Made changes (recommended by net users) to hpux10, ultrix4,
|
|
netbsd10, aux3 (replaced aux31). Added module for linux.
|
|
|
|
Fri Oct 10 1995 - wnl (3.4beta1)
|
|
Added user-contributed modules for SCO Unix, IRIX 5, HP/UX 10,
|
|
Pyramid DC/OSX. Changed Configure so that it runs in environments
|
|
whose c-shells have no 'eval'(!). Added support for multiple sort
|
|
ordering methods via the -o switch. This option requires support
|
|
from the machine dependent module: such support was added to
|
|
sunos5 (thus sunos54) and sunos4.
|
|
|
|
display.c: Changed CPU states display line to shorten the leading
|
|
tag if the data won't fit in the current width. Fixed a divide-by-
|
|
zero bug that affected ultrasparc servers (and potentially other
|
|
systems).
|
|
|
|
m_sunos5.c: Now asks the system for the correct pagesize rather than
|
|
assuming it is 4K.
|
|
|
|
Thu Mar 2 1995 - wnl (3.3 RELEASE)
|
|
Added module netbsd10 and renamed netbsd to netbsd08. Changed
|
|
Configure so that it does not use an initial default module name.
|
|
Made other compatability fixes to Configure. Added comments to
|
|
decosf1 concerning optimizer bug. Other documentation changes.
|
|
Added use of "prime.c" to Configure script.
|
|
|
|
Tue Feb 7 1995 - wnl (3.3beta6)
|
|
Still one more beta....
|
|
Fixes for sunos5 2.4 gcc core dump (it was an alignment problem).
|
|
Fixed and improvements for decosf1 (including use of format_k
|
|
for proper SIZE column formatting). Added modules freebsd20 and
|
|
ncr3000.
|
|
|
|
Thu Feb 2 1995 - wnl (3.3beta5)
|
|
One more beta....
|
|
Fixed a few bugs in the sunos5 port pertaining to casting and
|
|
very large memory counts. Added "ifndef HAVE_GETOPT" to getopt.c
|
|
to provide for conditional compilation of the getopt function.
|
|
Those systems that have getopt in libc can add -DHAVE_GETOPT to
|
|
the CFLAGS line in the module to prevent the function from being
|
|
compiled. Added sunos54 module to accomodate SunOS 5.4
|
|
peculiarities. Added module for aux3.1.
|
|
|
|
Wed Jan 4 1995 - wnl (3.3beta4)
|
|
This is really taking too long......sigh.
|
|
Fixed SIGWINCH handling once and for all. It now remembers the
|
|
number of processes you want displayed even thru window resizes.
|
|
Fixed buffer conflict in utils.c (itoa and itoa7).
|
|
Lots of small improvements to the various modules were made over
|
|
the past month: too numberous to list here. SunOS 5 module made
|
|
more secure thru use of seteuid calls (other SVR4 modules should
|
|
be modified similarly). One final MP fix to sunos5, too. Module
|
|
for decosf1 was modified to accomodate V3.0.
|
|
|
|
Mon Apr 18 1994 - wnl (3.3beta3)
|
|
I think I finally got a sunos5 module that will work on MP
|
|
machines. Fixed cpu states figure in osmp41a so that
|
|
percentages never exceed 100%. Added shell script "install"
|
|
since Unix vendors can't seem to make up their minds on what
|
|
options they want to use for the one that comes with the OS.
|
|
Added netbsd modules from Christos. Fixed lots of other little
|
|
things over the past few months that I have long since forgotten.
|
|
|
|
Wed Dec 15 1993 - wnl (3.3beta2)
|
|
Added module patches from various users: hpux9, sunos5.
|
|
Fixed bug with batch mode (screen_width wasn't getting set).
|
|
Changes to accomodate 64 bit machines.
|
|
Fixed some bugs in command parsing ("renice 19 " did something
|
|
unexpected).
|
|
|
|
Mon Aug 30 1993 - wnl (3.3beta)
|
|
Added lots of little patches from various users.
|
|
Added routines to utils.c for intelligent formatting of kilobytes
|
|
and time. These are intended to be used in the modules when
|
|
formatting a process line. Added code to "summary_format" in
|
|
display.c to do intelligent formatting of memory quantities.
|
|
Redid display.c to allow for varying line widths and dynamic
|
|
reallocation of the screen buffer.
|
|
Added a SIGWINCH handler to top.c!
|
|
Added a constant, MAX_COLS, to top.h which defines the absolute
|
|
widest line we will ever allow. Changed allocations of "char fmt"
|
|
in all machine modules to use this constant rather than an abitrary
|
|
number.
|
|
|
|
Fri Aug 13 1993 - wnl (3.3)
|
|
Changed return value definition of time-related functions in top.c,
|
|
display.c, and m_ultrix4.c to time_t (stuart@coral.cs.jcu.edu.au).
|
|
Fixed bug in display.c: line_update when start != 0.
|
|
|
|
Wed Aug 4 1993 - wnl (3.2 release)
|
|
Changes to Configure from Paul Vixie. Added modules for hpux9 and
|
|
bsd386.
|
|
|
|
Tue Jul 13 1993 - wnl (3.1 release)
|
|
More small changes and minor bug fixes. Brought bsd44 up to date
|
|
and added a module for svr4.2. Changed shar packaging to use Rich
|
|
Salz's cshar stuff.
|
|
|
|
Wed Jul 7 1993 - wnl (3.1BETA)
|
|
More changes and bug fixes to Configure. Applied some other
|
|
minor bug fixes and suggestions from the beta testers. Added
|
|
the "metatop" shell script and the "installmeta" rule to the
|
|
Makefile to make handling multiple machine models and OS versions
|
|
easier. Added INSTALL and FAQ files.
|
|
|
|
Tue May 18 1993 - wnl (3.1BETA)
|
|
Changed Configure to be compatible with most SVR4 environments
|
|
(differing output from "ls -lg"). Also changed Configure,
|
|
Makefile.X, etc., to look for module files in the subdirectory
|
|
"machine" (thanks to Christos Zoulas).
|
|
|
|
Tue Apr 20 1993 - wnl (3.1BETA)
|
|
Changed both occurences of "ls -1" in Configure to "ls". This
|
|
SHOULD produce the same result, and has the advantage that it
|
|
doesn't produce an error on a system 5 machine. Integrated other
|
|
changes recommended in the first round of beta testing.
|
|
|
|
Wed Mar 10 1993 - wnl (3.1BETA)
|
|
MAJOR CHANGE: I have added a required function to all machine
|
|
dependent modules, called proc_owner. It takes a pid as an argument
|
|
and returns the uid of the process's owner. Such capability is
|
|
necessary for top to run securely as a set-uid program, something
|
|
that is needed for SVR4 implementations to read /proc. I have
|
|
retrofitted all modules except dgux with this function, but was
|
|
not able to test most of them. Top should now run securely as
|
|
a setuid program. Added 386bsd and sunos5 modules. Added sunos4mp
|
|
module for MP Suns.
|
|
|
|
Sat Feb 20 1993 - wnl (3.1ALPHA)
|
|
Modified top.c and commands.c to compile correctly on System V
|
|
derived Unixes (especially SVR4), but in a way that doesn't rely
|
|
on an oracle-like declaration (that is, I don't use "ifdef SYSV").
|
|
Fixed some bugs in "Configure" and "getans". Added inspection of
|
|
env variable "TOP" for options, and made -I default to showing
|
|
idle processes. Added "u" command to change username restriction
|
|
on the fly. Created shell script "suntop" for poor multi-version
|
|
SunOS folks (like myself).
|
|
|
|
Wed Jun 3 1992 - wnl (3.0)
|
|
"max_topn" wasn't being used everywhere it was supposed to be
|
|
in top.c. Many cosmetic changes, including copyright notices in
|
|
all the .c files. Version number is now handled by version.c and
|
|
reflects the current patchlevel (which is initially set to 0).
|
|
Changed Configure and Makefile to allow configurable variables for
|
|
certain commands: shell, cc, awk, install. Updated README and
|
|
Porting. Ready to release to the world!
|
|
|
|
Mon May 18 1992 - wnl (2.9BETA)
|
|
Added modules provided by Christos Zoulas. Replaced screen.c
|
|
with one modified by Christos and that will appropriately select
|
|
and handle the sgtty, termio, or termios system. Integrated many
|
|
other changes recommended by Christos. Fixed (I hope) the "-b"
|
|
batch mode display bug. Had to change loadavg to load_avg to avoid
|
|
a conflict with 4.4BSD.
|
|
|
|
Mon Apr 27 1992 - wnl (2.8BETA)
|
|
Added modules provided by Daniel Trinkle. Added patchlevel.h,
|
|
but the patch level is not yet reflected in the version number.
|
|
Cleaned up m_sunos4.c a little.
|
|
|
|
Wed Apr 22 1992 - wnl (2.8BETA)
|
|
Major internal reorganization. All of the system dependent stuff
|
|
is now really and truly separated from everything else. The
|
|
system dependent functions are contained in a separate .c file
|
|
called a "module". The Configure script knows how to find and
|
|
set up these modules, but the human installer still needs to tell
|
|
Configure which module to use (no automagic determination of
|
|
machine type---sorry). Added -U option to specify one user's
|
|
processes, but there is no corresponding command...yet. Other
|
|
changes and improvements too numerous to mention here. Currently
|
|
there are only two modules: sunos4 and umax. But after this beta
|
|
release is sent around, I expect more to be written. I just hope
|
|
that the machine-dependent abstractions don't need to change in
|
|
the process.
|
|
|
|
Thu Mar 26 1992 - wnl (2.7BETA)
|
|
Beta release with minimal architecture support. Updated README
|
|
and added a first cut at a Porting guide. Added ioctl TIOCGWINSZ
|
|
code from top2.5+ (courtesy of David MacKenzie). I didn't even
|
|
try porting the Ultrix support since I don't have access to an
|
|
Ultrix machine.
|
|
|
|
Fri Oct 11 1991 - wnl (2.6)
|
|
This version was not widely released. It contained many changes.
|
|
Here are the major ones:
|
|
|
|
Put in Vixie's idle process hack.
|
|
|
|
Enhanced type field in new_message to handle delayed messages.
|
|
|
|
Changed u_process to automatically adjust for varying lines of
|
|
output. Management of screenbuf should now be completely contained
|
|
in display.c. Removed now extraneous code from CMD_number[12]
|
|
portion of command switch in top.c. This was the stuff that dealt
|
|
with zeroing out lines in screenbuf.
|
|
|
|
Finally made it all work correctly on a 386i. Problems I had to
|
|
overcome: kvm_nlist doesn't return 0 on success as advertised (it
|
|
returns 1 instead); the results of a kvm_nlist are different
|
|
(n_type can be zero even for a symbol that exists).
|
|
|
|
Serious rearrangement for processor dependent stuff. All nlists
|
|
are now in separate files with the suffix ".nlist". Most machine
|
|
specific code is in "machine.c" surrounded by appropriate ifdefs---
|
|
the goal is to eventually have all machine specific code in this
|
|
file. Managed to find a way to detect SunOS 4.x at compile-time:
|
|
this is contained in the include file "sun.h". Completely changed
|
|
the memory display line for SunOS 4.x---it now displays a far
|
|
more appropriate report.
|
|
|
|
Created the shell script "Configure" to aid in the configuration
|
|
step.
|
|
|
|
Fixed a bug in init_termcap: it will now tolerate an environment
|
|
which does not have TERM defined (thanks to Sam Horrocks for
|
|
pointing this out).
|
|
|
|
Tue Aug 9 1988 - wnl (2.5)
|
|
Added changes to make top work under version 4.0 of the Sun
|
|
operating system. Changes were provided by Scott Alexander of the
|
|
University of Pennsylvania. Thanks! Compile with "-Dsunos4" to
|
|
get them. Virtual memory statistics are not readily accessible
|
|
under 4.0, so they don't show up in the output.
|
|
|
|
Thu Jul 31 1987 - wnl (2.4)
|
|
Fixed a problem with the 4.0 Pyramid code. The label "cp_time"
|
|
doesn't exist in the 4.0 kernel anymore. I think the code Carl
|
|
sent me wants "percpu" instead. That is what I am using and it
|
|
appears to work. 375 code is still untested (at least by me).
|
|
Also picked a great deal of lint out of the source. Lint now only
|
|
complains about a very few nitpicky things (there are far too many
|
|
calls to "printf" to put a "(void)" in front of!), at least under
|
|
SunOS.
|
|
|
|
Tue Jul 28 1987 - wnl (2.4a)
|
|
Added changes for a Symmetrics Computer Systems s/375 machine.
|
|
Changes were provided by Paul Vixie. Thanks! According to Mr.
|
|
Vixie: "These changes were not made at, by, or for SCS proper.
|
|
SCS would probably be interested in them, but so far only the
|
|
users' group has them. They were made in February, 1987, to
|
|
version 2.1 of the program, by Paul Vixie
|
|
(dual!ptsfa!vixie!paul@ucbvax.Berkeley.EDU)." His changes were
|
|
integrated into version 2.3 to make version 2.4.
|
|
|
|
The SCS peculiarities are summarized in Changes.scs.
|
|
|
|
Tue Jun 9 1987 - wnl (2.3 for real)
|
|
Changed the includes for the extra code Carl sent me to only
|
|
compile on Version 4.0 Pyramid machines. This makes top still
|
|
compilable on pre-4.0 Pyramids. Specifically, this code is only
|
|
compiled when both "pyr" and "CPUFOUND" are defined.
|
|
|
|
Wed Jun 3 1987 - wnl (2.3 with Pyramid additions)
|
|
It's been a month and I still haven't done anything about
|
|
distributing this version. However, Carl Gutekunst from Pyramid
|
|
has sent me some extra patches for some of the Pyramid code. I
|
|
just added those and will make them part of 2.3. This fixes the
|
|
following Pyramid problems: adds the inclusion of <sys/systm.h>,
|
|
uses the correct size for getting the kernel value _ccpu (this bug
|
|
affected the Vax version as well), sums the elements of the percpu
|
|
array to calculate a cp_time value (for OSx 4.0).
|
|
|
|
Fri May 1 1987 - wnl (2.3)
|
|
I have finally finished all the changes for better support of
|
|
oddbal terminals. Added the low-level routine "clear_eol" which
|
|
makes handling terminals without "ce" easy: it uses spaces
|
|
instead. All direct uses of "clear_line" outside of screen.c have
|
|
been changed to use this primitive. A terminal with "os" is now
|
|
handled in such that all situations that need overwriting are
|
|
completely avoided (including several commands). This required
|
|
some changes to the way commands are translated into action (in
|
|
"top.c"). Made several important changes to display.c to prevent
|
|
overflowing of any of the fields. Specifically, more than 99
|
|
total processes and a cpu state that reaches 100%. Had to make a
|
|
small change to two casts in top.c, because the Sun 3.2 compiler
|
|
was giving warnings on them. Added the "-q" option which lets
|
|
root run top at a nice of -20 (in case he thinks he really needs it).
|
|
|
|
Tue Dec 30 1986 - wnl (2.2)
|
|
I think I fixed a bug reported by Julian Onions at Nottingham.
|
|
Occasionally, top will core dump when the sprintf in either
|
|
i_process or u_process overflows due to an exceptionally
|
|
unrealistic time value. I think it highly unlikely that top can
|
|
get a bad proc structure (although I suppose it is possible), but
|
|
the process time is read from the user structure, and that can
|
|
sometimes be part garbage. So, "get_ucpu" checks the value it
|
|
returns to make sure its formatted form will not overflow the
|
|
sprintf. If this doesn't fix the bug, then more drastic measures
|
|
will be necessary. I plan to make this version the official
|
|
"top 2.2". [[ This version was never distributed very widely. ]]
|
|
|
|
Tue Dec 2 1986 - wnl (2.2c)
|
|
Added to top.c the notion of a "failed command". When a command
|
|
produces a message (on the message line), an update does not
|
|
follow it. Before, the message was written and a new display was
|
|
shown---purposefully not overwriting the message. But the
|
|
improvements to handle overstriking terminals and terminals
|
|
without "ce" clear the screen before every display, which would
|
|
erase the message. Now, the message is displayed and top waits
|
|
another full time interval before updating the display. This
|
|
works much better all around.
|
|
|
|
Mon Nov 24 1986 - wnl (2.2b)
|
|
Created a new file, utils.c, and made appropriate changes to
|
|
Makefile. This new file holds all utility functions that can and
|
|
may be used by more than one "module". Improved i_memory and
|
|
u_memory (display.c) so that screen updates for the values
|
|
displayed are only changed when necessary. Also made the line
|
|
look better: the last fixes made for a rather ugly display.
|
|
Added the locally defined constant "LoadMax" and added code to
|
|
top.c to send the cursor home after a space command is entered if
|
|
the load average is higher than "LoadMax". This provides visual
|
|
feedback on loaded systems.
|
|
|
|
Mon Nov 3 1986 - wnl (2.2a)
|
|
Widened the format for memory usage so that it can display 5
|
|
digits. This makes that line look a little ugly---maybe I'll fix
|
|
that later. Screen handling now understands "os" and a missing
|
|
"ce". It treats them identically: clear the screen between each
|
|
display. Screen handling code now uses "cd" when appropriate
|
|
(i.e.: when user has shortened the screen). Made i_loadave clear
|
|
then screen and took out most of the explicit calls to "clear" in
|
|
top.c. This method is cleaner, especially in conjunction with
|
|
"os" handling. Added preprocessor variable "RANDOM_PW" for
|
|
systems that access the passwd file randomly (Sun's yp and 4.3).
|
|
With "RANDOM_PW" set, "getpwuid" is used instead of "getpwnam",
|
|
but uid->username mappings are still hashed internally (because
|
|
that is still faster than going to disk).
|
|
|
|
Mon Oct 6 1986 - wnl (2.1)
|
|
A bug with the kill command was pointed out by "dciem!tim"---
|
|
specifying a signal by name did not work correctly. This bug has
|
|
been fixed with a simple change to commands.c. Another bug made
|
|
the cpu state percentages incorrect the first time they were
|
|
displayed. This bug has also been fixed (changed top.c).
|
|
|
|
Thu Sep 4 1986 - wnl (2.0, at last)
|
|
This is the version that will (hopefully) get released to the
|
|
world as top 2.0.
|
|
Added the "r" and "k" commands for renice and kill, respectively.
|
|
This required adding a way to handle system call errors, and the
|
|
addition of the "e" command. Help screen and manual page were
|
|
changed to reflect this change. Changed all "#ifdef SUN" directives
|
|
to "#ifdef sun", and changed all "#ifdef PYRAMID" directives to
|
|
"#ifdef pyr". As much as I hate those choices of preprocessor
|
|
names (they too easily conflict with real variable names), it does
|
|
make automatic compilation possible---people don't have to change
|
|
the Makefile anymore for specific machines. The manual page was
|
|
changed to automatically incorporate the defaults as set in the
|
|
Makefile (including an infinite value for TOPN) and the way the
|
|
manual page is generated by the Makefile was changed to make
|
|
maintenance of this information automatic.
|
|
|
|
Mon Jul 28 1986 - wnl (still pre 2.0)
|
|
Real close now. I put in a new definition for the macro "pagetok"
|
|
that does an explicit shift of a constant expression involving
|
|
PGSHIFT. Appropriate checks are made if PGSHIFT is to small.
|
|
"pagetok" is now used exclusively everywhere to convert kernel
|
|
clicks to kilobytes. I added a full blown interactive mode with
|
|
the ability to change some of the runtime parameters (how many to
|
|
display, time delay, etc.) while top is running. I also
|
|
incorporated a few ideas from the net: control characters in the
|
|
command name are replaced with '?'; the '-S' option makes the
|
|
swapper and pager visible; options have been added to control the
|
|
number of displays produced (this makes it easier to make
|
|
performance snapshots with top). I have also added the notion of
|
|
"infinite" values for number of processes and number of displays.

I fixed a long-standing bug in the uid to username mapping code
|
|
that was only aggravated on the pyramids: it was an ill-defined
|
|
expression (akin to i = i++). I tweaked the proc_compar routine
|
|
for qsort slightly so that stopped processes were more likely to
|
|
show up. Manual page was updated to reflect all changes
|
|
noticeable to the user.

Tue Jul 1 1986 - wnl (pre 2.0 -- 1.9999?)
|
|
In the process of major revamping on the way to version 2.0.
|
|
I have completely done away with curses by adding my own screen
|
|
management routines in a separate file (screen.c). The rationale
|
|
for this is that top knows a whole lot more about what is and is
|
|
not redundant on the screen and can compare simple integer values
|
|
where curses would have to compare strings. This has turned out
|
|
to be a very big win speed-wise. The proc_compar routine for
|
|
sorting has been rewritten to include several more keys. I
|
|
decided this was necessary when I noticed that the "top" process
|
|
itself kept disappearing off the top 10 list on a Sun-3. All the
|
|
processes had the same percentage (0%) and the sort wasn't really
|
|
doing anything worthwhile. I changed the expression that computes
|
|
memory usage to use the ctob macro instead of just assuming that
|
|
pages were 512 bytes. More work still needs to be done before
|
|
this version is usable. I changed options-processing to use
|
|
getopt and added appropriate incantations to the Makefile.
|
|
|
|
Wed Feb 20 1985 - wnl (still 1.8)
|
|
Put in the ifdef FOUR_ONE statements to make top still compilable
|
|
on a 4.1 system. Apparently, there are some users out there that
|
|
need this functionality. Oh well. I don't guarantee any of it,
|
|
since I can't test it. Made appropriate changes to README and
|
|
final installation related changes to Makefile.
|
|
|
|
Sat Feb 2 1985 - wnl (1.8)
|
|
Removed all the ifdef FOUR_TWO statements and made "top" into a
|
|
4.2 only program. If someone really wants to still run it on 4.1,
|
|
then they can do all the work. We don't have a 4.1 machine
|
|
anymore, so I don't even know if the thing still works under 4.1.
|
|
Cleaned up the Makefile and the README. Added installation rules
|
|
to the Makefile, as requested by several sites. Fixed a very
|
|
obscure divide-by-zero bug. Added a second "key" to the qsort
|
|
comparison function (proc_compar) so that comparisons are based on
|
|
cpu ticks if the percentages are equal (provided by Jonathon
|
|
Feiber at Sun).
|
|
|
|
Tue Dec 11 1984 - wnl (1.7)
|
|
Added the virtual and real memory status line to the header area
|
|
(provided by Jonathon Feiber at Sun)
|
|
|
|
Tue Nov 20 1984 - wnl (1.6)
|
|
Added an "exit" if sbrk's fail. Added changes from Jonathon
|
|
Feiber at Sun: ifdef SUN to make top work on Suns (they don't use
|
|
doubles in the proc structure), register declarations, check for
|
|
getting a user structure that has disappeared since the proc array
|
|
was read (it used to die, now it just shows the process as swapped).
|
|
|
|
Tue Nov 13 1984 - wnl (1.5)
|
|
If the number of displayable processes ("active_procs") was less
|
|
than the number of requested processes ("topn"), top would
|
|
segmentation fault. This bug has been fixed. Thanks to Prentiss
|
|
Riddle at ut-sally for pointing out the existence of this bug.
|
|
|
|
Tue Oct 23 1984 - wnl (1.4)
|
|
Finally fixed the hash table bug that caused processes owned by
|
|
root to sometimes appear with either no name or a different name
|
|
that had UID 0 (such as "operator"). Removed all the ifdef DEBUG
|
|
blocks to make top ready for distribution to the real world.
|
|
|
|
Sun Apr 8 1984 - wnl (still 1.3)
|
|
Made some slight changes to the display format. It now looks more
|
|
aesthetically pleasing. Added some preprocessor constants so that
|
|
the two defaults (number of processes and seconds of delay) easier
|
|
to change.
|
|
|
|
Thu Apr 5 1984 - wnl (1.3)
|
|
Changed the order in which things are done at initialization time.
|
|
This way, if an error occurs before starting the main loop, curses
|
|
will never get started. Also changed other error handlers so that
|
|
endwin() is called before any flavor of exit. Specifying a number
|
|
of processes that is more than the screen can handle is no longer
|
|
fatal. It displays a warning message and pretends the user
|
|
specified the maximum for the screen. Finally cured all the TSTP
|
|
blues (well, almost all). I removed my TSTP handler and convinced
|
|
the system to always use the one that curses sets up. Turns out
|
|
that "sleep" was stepping all over it during a pause. So, I don't
|
|
use sleep anymore. The only problem that remains with it now is
|
|
redrawing the old display before updating it after a pause.
|
|
|
|
Tue Apr 3 1984 - wnl (from 1.0 to 1.2)
|
|
I changed the format of the TIME column from just "seconds" to
|
|
"minutes:seconds". I also made pausing work correctly. Screen
|
|
redraws with an up to date display. For compatibility with 4.2, I
|
|
changed the name of the "zero" function to "bzero". The makefile
|
|
has been altered to handle versions for 4.1 and 4.2, and README
|
|
has been updated to reflect these recent changes.
