99d71ad581 bprocps: fix order of operations for %use of slabinfo
In some environments, 100 * nr_active_objs is calculated at first,
and lower 32bit of the result is divided by nr_objs.
If 100 * nr_active_objs > 42949672, %use will be incorrect.

3f5b75035e 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.

dad56cc954 top: minimal necessary corrections to the man document
After experimenting with those 4.5 kernel enhancements
to /proc/<pid>/status, that newly added overview topic
'Memory Types' was found to be in need of some tweaks.

In addition, the 'DATA' description wasn't quite broad
enough since explicit private file mappings impact it.

( have been the original issue 21 commit. instead it )
( showed an invalid SHA-1 hash. i believe i have now )

5dcbcd00fe top: add additional memory information to the man page
In response to Issue #21, the commit referred to below
provided some much needed improvements and corrections
to topic `3a. DESCRIPTIONS of Fields' in the man page.
However, it assumed a reader possessed much background
knowledge that may not, in truth, actually be present.

So without, hopefully, insulting anyone's intelligence
this patch offers an expanded discussion of some terms
and concepts within a separate section under OVERVIEW.

[ plus it affords an opportunity to incorporate that ]
[ extremely useful table from Florent Bruneau's post ]

e4bbd3ca1a top: improve/correct several memory fields in man page
Due to quirks in kernel memory management plus limited
information available from /proc/<pid>/status & statm,
some of the top resident memory fields were capable of
exceeding available physical memory. So this commit is
a bit of a band-aid until the kernel has been changed.

Such a change appears to be on the horizon in the form
of three new fields to be added to /proc/<pid>/status.
While not preventing 'resident' memory from apparently
exceeding physical memory, the new fields will help to
clarify any such contingency, if/when we exploit them.

717d73f1dd top: tweaks to vertical scroll management & 'i' toggle
The commit referenced below claims to disable vertical
scrolling when idle tasks weren't being shown. However
it really addresses only a point in time when that 'i'
toggle is keyed. Left untouched were the up/down keys.

So this commit will simply finish the job of disabling
vertical scrolling whenever tasks which have used some
CPU are the only ones which are currently being shown.

1af18812b2 enable transparent large file support
Historically LFS mattered only to open/read large files.  A few programs
here use open/seek, but not generally on files that are large.  However,
LFS also applies to stat which procps does in a bunch of places -- some
filesystems have 64bit inodes and attempts to do a 32bit stat will throw
an error.

Enable transparent LFS everywhere to avoid this.

da715e3ca0 Replace %Lu with standard %llu
Multiple scanf()s use the GNU-permitted %Lu. This is not supported in
other libraries and isn't to the POSIX specification. The L modifier
is only used for floats in POSIX.

Replacing %Lu with %llu is the same for GNU libc (scanf(3) says as much)
but means other libraries will work fine.

Closes: #19

32e1b2e297 A locale-independent strtod
There is a need in some utilities to have a way of accepting both
types of decimal points "." and ",". The only way seems to be to
rebuild strtod().

This new function will accept "123.456" and "123,456" as 123.456
and considers them the same number. It means we lose thousands
separator, but this is rarely used.

test scripts are added to check the function returns the proper
values. There was simpler predecessor that got stuck on negative
0 or -0.123 which these tests flushed out.

94e4749be3 top: extend '=' key to include active 'locate' request
It is documented behavior that when certain other keys
are active, sorts column highlighting will temporarily
be disabled. Among those keys is the 'L' (locate/find)
provision. The equals ('=') key can be used to restore
column highlighting by resetting other keys, except 1.

When a locate/find is active, the '=' key will have no
effect on 'x' column highlighting, which still remains
disabled. Further, when 'L' is active an 'x' keystroke
is processed changing the state of column highlighting
but without any visual clue (since it's yet disabled).

So this commit just extends the '=' key to embrace 'L'
processing resets, just like other highlight disabling
keys while avoiding 'x' state changes if approproiate.

Craig's recent commit under that newlib branch dealing
with namespace support has prompted me to review top's

is zero, top displays a dash ('-'). This will mean the
justification toggles ('j/J') will behave incorrectly.

This patch simply allows the potential zero to display
or be suppressed with the already existing '0' toggle.

b2f49b105d Closes: #9 ps: Remove Unix98 output limitations
ps previously followed the Unix98 standard when it comes to
user-defined output, sometimes. This meant you could have
user output format with a header that included commas and
equals signs. It was dependent on if ps thought you wanted
sysv or bsd format and THAT was dependent on things in previous
options.

It was very confusing to a user because
 ps p $$ -o pid=,comm=
gave you a two-column output but
 ps -p $$ -o pid=,comm=
would give you a one column output with the header ",comm="

The -p versus p means (to ps) you want sysv or bsd parsing.
Unix98 standard or not, this is plainly just silly.

The commit removes any of the quirks Unix98 has with user defined
output.  If you really wanted a ps header with commas in the output,
today isn't your day.

Closer examination revealed that if a valid float string is

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().
