This commit primarily involves renaming functions plus
reorganizing logic in preparation for the next changes
which will hopefully yield the 'final solution' to the
excessive SIGWINCH signals under most window managers.
In this specific patch, the most significant change is
the introduction of a new 'ioa' function (io avail) to
focus all logic dealing with unsolicited user keyboard
input and exposed to signals and/or optional timeouts.
That new function is where our signal overload will be
ultimately defeated, if it is at all humanly possible.

Prior to this commit, top has always taken the easiest
(safest?) approach when dealing with those troublesome
SIGWINCH interrupts. Whenever the user was on a screen
other than the main display, any signal received would
force an immediate exit, returning to the main screen.
With these changes, top will retain the user's current
position regardless of what screen he/she was viewing.
In support the following additional changes were made:
* the initial help screen requires an explicit end key
` not 'any other key' formerly used to request an exit
* the colors mapping screen instructions were improved
* ^Z response was made immediate, eliminating the flag
* the sigaction's SA_RESTART flag had to be eliminated
* sigprocmask logic was normailize to the bare minimum
* the POSIX.1-2004 async-signal safe functions used in
` the signal handlers were acknowledged and documented

There existed a small chance that the display could be
corrupted when a search string was found within a row.
For that to happen, conditions like these were needed:
. a very short Locate string was active in some window
. the string matched part of a terminfo <esc> sequence
. that sequence was used in highlighting running tasks
. the 'x' toggle was active (sort column highlighting)
One solution to this potential problem was to manually
turn off sort column highlighting before using Locate.
But rather than rely on a user remedy, we'll automate.
Since other top provisions were already being enforced
when Locate was in use (off 'i' and/or 'u'/'U'), we'll
now also force column highlighting off when the search
string in a given window is not empty. However, unlike
idle tasks and user filtering, when that search string
*is* emptied, we restore highlighting for that window.

This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.

Earlier this year, the switch from KiB to Mib as shown
in top's summary area was postponed to those occasions
when KiB exceeded 8 digits. In hindsight that may have
moved top in the wrong direction, given the difficulty

This commit adds a new 'E' interactive command used to
cycle the displayed memory amounts ranging from KiB to
TiB. Thus, users can choose the radix they wish shown.

With the recent inspect search highlight provisions in
place, the lack of highlighting in task based searches
has grown from being only irritating to a real defect.
Thus, this commit introduces parallel functionality to
those searches initiated within a visible task window.
And just as separate inspect searches are possible for
each selection, per window task searches are provided.
However, it should be noted that there are differences
between task based searches and inspect type searches:
* There is no concept of out-of-view data when dealing
. with task rows -- if the data can't bee seen, it has
. not, in fact, been constructed from a proc_t struct.
* While inspect data is output at the character level,
. up to now all task display data was only potentially
. output and it was always based on a complete string.
* With task search highlighting, rows now containing a
. match must be output in pieces and, therefore, can't
. be optimized away like other rows which haven't been
. been altered. This is because top cannot predict the
. the contents of a search string or, how many matches
. might occur in a given row. Short search strings and
. many matches would raise buffer needs geometrically.

This commit extends Inspect provisions for 'find/next'
to each individual selection. Thus a user can maintain
multiple active searches without having to reissue the
locate command whenever the current selection changes.
To emphasize this feature the View screen now displays
the current active locate string or 'N/A' if inactive.
Such a reminder is important when no found matches are
present on the 1st display page, given that they would
otherwise be apparent via the additional highlighting.

We have modeled the Inspect search provisions on those
provided by the 'less' pager. With this commit we take
the next step and provide for highlighting any strings
matched (and in view). Of course, top will continue to
adjust the beginning column so as to bring out-of-view
matches into view, while highlighting visible matches.
However, top won't emulate every 'less' behavior since
the following are seen as flaws in the user interface.
* when viewing true binary data, less makes no attempt
. to smooth the right margin by truncating unprintable
. symbols, thus creatng ragged unappealing right edges
* when viewing true binary data, less will always fail
. search requests regardless of surrounding characters
* less refuses to bring out-of-view found matches into
. view by adjusting the left-most column, if necessary

Previously top would warn users if an older version of
an rcfile was about to be overwritten. That's assuming
that RCFILE_NOERR was not defined. This left, however,
other potential rcfile issues or questions unattended.
For example, if a faulty 'inspect' redirected echo had
overwritten all window entries or if the inspect entry
was not 'pipe' or 'file' (actually, just a 'p' or 'f')
then top would silently accept it but look no further.
With this commit top will try to process every inspect
entry, while preserving unrecognized entries. Plus all
other non-fatal rcfile errors will now alert a user to
the potential overwrite when the 'W' command is given.

This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.

The 'refactor and enhance column width management'
recent redesign produced many subsequent benefits,
the latest of which is automatically sized fixed-width
non-scalable columns.
As expected, there was a cost associated with these
many enhancements. That cost has now been identified
as a 1-4% performance degradation, depending on which
fields are being displayed.
This increased cost arises principally from current
drawing related function calls, whereas top-3.3.3 did
most of its drawing via macros effectively inlining
those duties.
This commit inlines the equivalent drawing functions,
thus eliminating the function call penalty, and places
this top on a par with top-3.3.3. The trade off is a
modest additional 4k in executable size.

The recent introduction of a column widths override
(the 'X' command) provided for a user input amount
to be added to default field size which ranged from
5 to 10 bytes.
While that approach could prevent truncated data, the
different default sizes would almost certainly mean
some precious screen real estate was waisted.
This commit introduces the concept of dynamic widths
where top will add only enough to a field default to
prevent truncation for that specific field.
Now users have a choice between their explicit width
override or a width chosen by top to exactly match
display needs. The former is immediate but likely
wastes some horizontal space while the latter is
iterative but will be sized precisely.

Note:
There are no restrictions on the amount added to
the defaults. The user is free to vastly exceed
screen limits which simply means such fields can

The TREE_RESCANS #define (formerly TREE_ONEPASS) has

redesigned. The chance of dangling children has been
eliminated and overhead reduced.
We now order processes on start_time (non-display)
and are therefore immune to any pid, ppid or tgid
anomalies when pid values wrap.
The new algorithm also accommodates any distortions
caused by the 3.3 kernel 'hidepid' provisions --

When top introduced true line input editing, the
ability to paste keystrokes was lost. This remains
a necessary evil so that top has an opportunity to
translate cursor motion keystrokes into terminfo
escapes during line input. Motion keys themselves,
of course, can never be pasted.
If pasting ever became more important than input
editing, then native termios support should have been
available via a define called TERMIOS_ONLY. But a
recent commit, eliminating what was thought to be
obsolete logic, rendered the alternate linein()
function virtually useless.
Similar to top-3.2.8, when native termios input is
functional, these abberations can be experienced:
. cursor motion keys will appear as escapes
. excessive input can cause line wraps
. ^Z during i/p is not be honored until <Enter>
. SIGWINCH during i/p corrupts screen temporarily
In hindsight, it now seems that the ability to paste
keystrokes may indeed outweigh any shortcomings of
native termios support. This is especially true if
one is preparing to search ('L') for some lengthy
process command line contined in the clipboard.
Thus, this patch fixes the alternate linein() function
and changes TERMIOS_ONLY to TERMIO_PROXY so that top
now defaults to using native termios input. In turn,
that will restore the paste keystrokes capability.

Under openSUSE, old top uses additional fields for
out-of-memory reporting. As a result, under the
original approach to rcfile conversion, new top would
issue a fatal corrupt window entry message asking that
the rcfile be deleted.
This patch extends the conversion range to include
the extra openSUSE field characters. It's effective
when ./configure specifies the --enable-oomem option
which in turn defines OOMEM_ENABLE.
This commit also makes the conversion logic slightly

less than that will be handled seemlessly.

At one time, new top silently defaulted when an rcfile
was found to be incompatible. This is exactly what
the old top did. However, after some discussion it
was decided top should alert the user and thereby
save the system administrator some headaches.
Now, some are upset over the fatal error, proving you
can't please everybody. But in all fairness, given
the difficulty of customizing old top, any reluctance
to delete an old saved rcfile is understandable.
To ease transition to this new top, old style rcfiles
will now be honored and converted to the new format.
And if not disabled at ./configure time via CFLAGS,
a user will be warned when an old style rcfile is
about to be overwritten using the 'W' command.
Lastly, the config validation logic was enhanced to
help ensure both types of rcfile haven't been edited
manually and possibly made unuseable.

We originally approached the potential problem of

The latest information suggests that it may have
been due to a kernel anomaly that has since been
corrected.
Yet even without such a cpu, wide disparities in
tics allocation among all available cpus have
sometimes been observed -- spikes as it were in
the normal pattern. This has happened under both
version 2.26.38-13 and 3.0.0-15 kernels.
The small amount of additional code addressing the
original problem carries very little overhead. It
is being retained to afford protection against any

Due to a poorly constructed temporary fprintf
used during development, an earlier commit went
a little too far in its computations. The net
result was the code looked nice but actually
accomplished nothing.
It is the /proc/stat line 1 (summary line)
whose tics must be used in establishing the
threshold boundary. And that calculation
need be performed just once per frame.
This commit ensures one threshold calculation
per delay interval no matter how many cpus
are ultimately displayed.
It also corrects scalability by factoring in
the total number of online processors.
Reference:
commit 9e7dd43ab7
The original approach to potential % CPU distortion due
to Nehalem type cores being turned off completely when
idle worked ok until the user typed something.
At that point, elapsed tics would no longer equal the
calculated value producing an undesirable 100% idle
condition until the next update or <Enter/Space> key.
This commit employs actual elapsed tics in determining
whether a cpu should be considered idle and thus makes
top's individual cpu display immune to user keystrokes.
This patch provides for cpu cores which can be turned
off completely when idle (Nehalem, etc.) thus registering
very few or no tics since the last update cycle.
When CPU_ZEROTICS is not defined (the default), any
displayed cpu with less than a certain amount of total
tics will show as 100% idle. That amount is tempered
by the delay interval and total number of cpus.
This commit also satisfies the Debian 'top_nohz' patch
(11/24/09) in a slightly more efficient manner. That
patch concerned kernels built with CONFIG_NO_HZ.

Prior to this patch, top was able to handle any hotplugged
cpus *added* to the system in two distinct ways.
1) Newly added cpus would be detected by sysinfo_refresh
calling the library's cpuinfo function, which occurs
at most every 5 minutes.
2) The user could force a refresh using either the
<Enter> or <Space> keys.
Unfortunately, the *loss* of a cpu would produce an early
exit due to a /proc/stat read failure. Such a failure
can be produced in the following way:
sudo echo 0 > /sys/devices/system/cpu/cpu??/online
This commit allows top to tolerate the loss of cpus.
It also provides for more efficient CPU_t management,
especially for massively parallel cpu environments.
Note: Changes to the cpu compliment can produce a single
cycle distortion of cpu percentages. Such distortion is
most visible when each cpu is being displayed. It can
be eliminated with a forced refresh via <Enter>/<Space>.
This commit addresses a long standing buglet (debian #441166) which
surfaces when the display mode is switched between task and threads.
An extra procps refresh is now forced upon such a transition which
parallels the approach used at startup for the exact same reason.
