91df65b9e7 docs: Document I idle state in ps and top
Linux 4.2 provided a new process state of I which is used for an idle
kernel thread. This new state means that kernel threads do not
contribute to the loadavg as they are no longer state D or S but I.

While both ps and top displayed this state, it wasn't documented in
either manual page until now.

55a42ae040 top: allow more flexible approach for startup defaults
Those references below offer more detail regarding the
default startup changes beginning with version 3.3.10.

It is important to remember that all such changes were
supposed to impact only new users or users who had not
saved the personal config file (via that 'W' command).
However, I introduced a bug wherein the rcfile was not
fully honored. This gave the changes a bad reputation.

That bug was corrected in release 3.3.11 but the issue
of default startup options keeps resurfacing. And it's
clear there's no consensus on what should be included.

Our --disable-modern-top configure option is of little
help since it remains an all-or-nothing approach. What
we need is an answer offering unlimited customization.
So, this commit will provide distribution packagers or
system administrators with a much more flexible way to
set their own preferred startup default configuration.

A new rcfile is being introduced: '/etc/topdefaultrc',
whose format/content is the same as a personal rcfile.
Thus once a 'proper' enterprise configuration has been
established and saved via 'W', it can be copied to the
/etc/ directory. Thereafter, startup in the absence of
a saved rcfile will use that configuration as default.

Now if a distribution packager or system administrator
wishes to expose their users to some of top's advanced
capabilities they can do so gradually. Perhaps setting
up graph mode for summary area task and memory display
while retaining the %CPU sort could be tried. Or maybe
showing colors, but better customized for a particular
terminal emulator. Such possibilities are now endless.

[ in exploiting this new capability, i hope that the ]
[ other windows (alt display mode) aren't overlooked ]

aab30a0aad top: protect against the anomalous 'Mem' graph display
Until this patch, top falsely assumed that there would
always be some (small) amount of physical memory after
subtracting 'used' and 'available' from the total. But
as the issue referenced below attests, a sum of 'used'
and 'available' might exceed that total memory amount.

I'm not sure if this is a problem with our calculation
of the 'used' amount, a flaw in the kernel 'available'
algorithms or some other reason I cannot even imagine.

Anyway, this patch protects against such a contingency
through the following single line addition of new code
. if (pct_used + pct_misc > 100.0 || pct_misc < 0) ...

The check for less than zero is not actually necessary
as long as the source numbers remain unsigned. However
should they ever become signed, we'll have protection.

[ Most of the changes in this commit simply separate ]
[ a variable's definition from its associated logic. ]

62da5ee3ce top: refresh interval accepts non-locale decimal value
For the past 3 years top has fully honored that locale
LC_NUMERIC setting which impacts his refresh interval.
For the past nearly 5 years top has saved that refresh
value in a locale independent form in his config file.

With this commit we'll intentionally break top so that
a comma or period will be accepted for the radix point
regardless of what that LC_NUMERIC may have suggested.

The current locale LC_NUMERIC will, however, determine
how the delay interval is displayed in the 'd' prompt.

[ This position is better than the approach employed ]
[ by those coreutils 'sleep' and 'timeout' programs. ]
[ Both claim to permit floating point arguments. But ]
[ neither one will accept the comma separator should ]
[ the locale be a country that in fact uses a comma. ]

aa41c309dd kill: -l space between name parses correctly
This was supposed to be just a cherry-pick of the referenced
commit. However there were two problems:
 1. kill code was moved out to its own file
 2. strtosig() had a latent bug where signal numbers were not
 converted to names.

Original note:
kill -lHUP would work correctly, but kill -l HUP would not.

The list option in kill was hit by a quirk of getopt_long where an
option with an optional argument would not attempt to get the argument
beyond the space, even though a mandatory argument would do that.

The fix is a kludge to scan to the next argument and if it looks
like something we can use, use it. Lucky for us, the list option is
one where parsing can stop immediately.

Thanks to Brian Vandenberg for the way forward.

3ad417c0c0 top: address the argument parsing quirk involving '-h'
There exists the possibility that a 'putp' call can be
issued before the 'setupterm' invocation has occurred,
as is reflected in a bugzilla report referenced below.

Strangely, such a SEGV isn't always triggered as logic
would suggest it ought to be. I experienced a fault in
these environments with the associated curses version:
. archlinux, procps-ng 3.3.12, ncurses 6.0.20170429
. fedora-25, procps-ng 3.3.10, ncurses 6.0.20160709
. opensuse-42.2, procps-ng 3.3.9, ncurses 5.9.20140201
. gentoo, procps-ng 3.3.12, ncurses 6.0.20150808
. slackw-14.2, procps-ng 3.3.12, ncurses 6.0.20160910

Whereas under these environments there was no problem:
. ubuntu-17.04, procps-ng 3.3.12, ncurses 6.0.20160625
. debian-test, procps-ng 3.3.12, ncurses 6.0.20161126
. mageia-5.1, procps-ng 3.3.9, ncurses 5.9.20140323

[ as an aside, the expected result in the bug report ]
[ is incorrect and should mention the '1' parameter. ]

[ however, until release 3.3.13 when the '1' becomes ]
[ a valid switch, numbers are not detected when used ]
[ with any switch which doesn't require an argument. ]

[ you're welcome to treat that as a separate bugglet ]

5e708c5db7 top: provide -1 command line switch as 'Cpu(s)' toggle
If built without ./configure --disable-modern-top, the
program displays each cpu individually providing there
is sufficient vertical screen real estate. For massive
SMP environments this will necessitate use of a config
file where the cpu summary toggle ('1') could be saved
via the 'W' command. But, an rcfile may not be viable.

So this commit introduces a '1' command line switch to
emulate exactly the effects of the interactive toggle.

And since it is our first numeric switch some existing
parsing logic had to be changed slightly. Such changes
are, in truth, an improvement. For example, instead of
seeing "inappropriate '2'" with ./top -2 we'll now see
the vastly more appropriate error "unknown option '2'.

b2bd65407a top: provide -E command line switch for memory scaling
In their 3.2.7 version of top, Redhat introduced an -M
switch to automatically scale Summary Area memory data
to avoid truncation (and the resulting '+' indicator).

The procps-ng top does not employ suffixes with memory
data nor does it allow for different scaling with each
separate value. Rather, scaling appears at line start.

If built without ./configure --disable-modern-top, the
Summary Area memory will be scaled at GiB which should
lessen chance of truncation. Otherwise KiB was used to
reflect such memory, increasing the truncation chance.

And while 'W' can be used to preserve some appropriate
scaling value, there are arguments against such rcfile
approaches as cited in the issue and bug report below.

So this commit will bump the Summary Area memory scale
factor from KiB to MiB when using --disable-modern-top
as a concession to that Redhat bug report noted below.

And it also introduces a new command line switch which
can force any desired scaling regardless of the rcfile
or which ./configure option might have been specified.

[ for top's help text we'll show 'E' as if it were a ]
[ switch without arguments in order to keep the help ]
[ text displayable without wrap in an 80x24 terminal ]

[ the man page, however, will show all k-e arguments ]

f318be467b top: show fewer decimal places for memory (by default)
After much reflection I've come to the conclusion that
displaying 3 decimal places (usually) when memory data
had been scaled is no longer optimal with today's ever
increasing amounts. And given that not all task memory
fields are the same widths, inconsistencies can easily
arise as illustrated and discussed in the issue below.

Instead of unilaterally reducing the number of decimal
places, this commit will sneak in such a change via an
existing configure option that was very likely unused.

The former 'disable-wide-memory' option has now become
'enable-wide-memory', which can be used if the current
behavior (3 decimal places) is preferred. Without that
option, whenever memory is scaled beyond KiB, just one
decimal place will be shown in Summary and Task areas.

And Task area field width will no longer be changed by
this revised configure option. Instead, all such field
widths will now be fixed at the former maximum values.

ff05573f0d pkill: Return 0 if successfully killed process
Original report:
When trying kill a process with insufficient privileges (see blow),
pkill displays the error message “... failed: Operation not permitted”,
but returns 0. Surely it should return 3?

$ pkill syslogd ; echo $?
pkill: killing pid 373 failed: Operation not permitted
0

Return value 0 means one of more things matched. For a pgrep (which
shares code with pkill) this makes sense, there was a match. It seems
wrong for pkill to return 0 when it in fact could not do what you told
it to.  However return value 3 means a fatal error and it's not fatal.

Looking at other programs when trying to kill things it cannot kill.
shell kill returns 1, procps kill returns 1, killall returns 1, skill
returns 0 (and says it was successful!, ah well poor old skill)

The consensus seems to be that you return 1 if you cannot kill it, even
if you found it. In other words the return value for both not found and
not able to kill it is the same.

pkill only returns 0 if something was killed. This means we found a
match AND the kill() system call worked too.

f888a30d23 library: find tty device name of process quicker
The procps library attempts to work out the tty of a process
through several methods. For things like /dev/tty123 or
/dev/foo it works fine.

For tty devices that put the minor number in a directory
of the major name this fails. So then we have to fallback
to stating things like the processes STDERR and try again.

Considering a lot of processes sit on ttys such as
/dev/pts/3 this is a lot of wasted time. At the point of
entering driver_name we know "/dev/pts" and we know "3"
we just didn't join them up the right way as this is old
code.

This change now looks for /dev/pts/3 as well. It does it
after looking for /dev/pts3 so the behaviour is the same.

7fdab1fcc8 pidof: check cmd if space in argv0
A difference in behaviour between the sysvinit and procps pidof
was that the procps one would sometimes not find process that
the sysvinit one did.

The difference is that if a space is found in argv[0] then sysvinit
would look at cmd for a match. This isn't perfect and more of a
best guess but does often work.

procps pidof now follows the same "standard". The most obvious
difference is with kde based processes and incoming ssh connections
with sshd.

If the -s option was the first option on the command line, free
would report seconds argument failed. This only appeared on the
Debian free, not the one in git.

Closer examination revealed that if a valid float string is
given to strtof() it doesn't set errno to 0, but just leaves it
alone. As we are explicitly testing errno for overflows, this
means the previous errno change is picked up here.

The simple answer is to set errno to 0 before calling strtof().

313f936739 ps: enable sort by etimes
ps has two columns showing the same data which is elapsed time, just
the format is changed:
 etimes - elapsed time in seconds
 etime  - elapsed time in DD-hh:mm:ss

ps used to only sort by etime but not etimes, by making etimes
and alias of etime for sorting both flags work.

92071e963e pmap: print process even if smaps unreadable
pmap would previously print the process name if
/proc/PID/smaps could be opened, even if subsequent
reads failed.  This actually occurs with other users
PIDs.

Kernel 3.18rc1 introduced a change where the file could
not been opened, meaning pmap -X 1 previously showed
the process name and nothing else but NOW shows nothing
make check failed because of this.

This change prints the process name even before trying to open
the file, returning it to previous behaviour.
Thanks to Vincent Bernat for some analysis.

7610b3128e skill: fix command line with signal
If skill was used with a signal number then it would intepret
the command line with last option interpreted twice. This often
confused the program so it just would end up killing nothing.
So this would work:
skill -t pts/0
This would not:
skill -9 -t pts/0

The kill path (in the same file) uses the same logic that has
been introduced here.

8ef6cd91fc top: retire old stale startup defaults in favor of new
For over a decade top has used a startup configuration
mimicking the original redhat top. This decision dates
back to when the forked Sourceforge version was trying
to win over users in battles with that ancient kludge.

Will anybody deny that those defaults are coyote ugly?

Well, it is time that top presented a more modern look
at startup, providing that no saved rcfile exists. But
just in case some distro prefers that old, comfortable
look, there's the '--disable-modern-top' build option.

[ Pssst. With the widened memory fields it turns out ]
[ the 'Mem' default window had become almost useless ]
[ on an 80x24 terminal since %CPU & COMMAND were out ]
[ of view. So some other defaults were tweaked a bit ]
[ whether or not --disable-modern-top was specified. ]

2199af404a top: maximize recent locale aware numeric enhancements
When startup argument parsing was recently enhanced to

This patch extends such enhancements to a running top.

SIGCONT is a continue signal.  It seems that some zsh setups can send

This change just uses the default handler which will continue a stopped

0fe393ff27 top: inoculated against a window manager like 'screen'
If top were invoked under the 'screen' window manager,
writing the terminfo string 'exit_ca_mode' at top exit
would not restore the display to the state existing at
the time top was started. That's what occurs normally.
The net result of that failure was a corrupted screen.

However, there is a 'screen' configuration option that
will produce proper 'rmcup' behavior, but it is off by
default. That screencr option is known as 'altscreen'.
I stumbled across this provision by cloning the screen
git repository then searching for references to 'cup'.

If 'altscreen on' had been in either the /etc/screenrc
or the $HOME/.screenrc configuration file, my poor old
top would never have been accused of such corruptions.
Of course, the Programming Gods decree that any simple
solution for our problem must always be revealed last.

So before discovering that rc option, another approach
was taken involving top only. With just a little extra
refactoring of top display logic he was made immune to
any such quirk in the implementation of 'smcup/rmcup'.

I always feel good about any enhancement that actually
reduces the total number of lines of code. Even though
this change involved mostly rearranging some logic, it
yielded one less line (can't judge by diffstat because
of braces & notes). Anyway, rather than requiring some
change to a screenrc file, now we are self-sufficient.
