13f20a4811 free: reusing 'shared' for Shmem
Previously the shared memory column was always zero
for 2.6 series kernels (and later) due to the fact,
that the value was taken from the MemShared entry
that disappeared with 2.6 series kernels.
Later a new Shmem entry appeared in the /proc/meminfo
file and the 'shared' column now displays either
the MemShared or the Shmem value (depending on their
presence - the presence is mutually exclusive).
If none of the two entries is exported by the kernel,
then the column is zero.

An unpleasant thing happened when I comitted the shmem support
for the 'free' tool. We already had a merge request from
Adrian Brzezinski in the queue, doing exactly the same.
As Adrian deserves credits, I'm reverting the change
and re-applying with the next commit in order to make
him a part of the project history.

06c19f5ba4 top: swat bug affecting batch mode and width provision
Normally, the internally tracked 'Screen_cols' can not
exceed the lessor of 512 or actual screen width. There
was one case, however, where that 512 byte upper limit
was no longer properly imposed as it should have been.

When operating in 'Batch' mode the actual screen width
was allowed to be exceeded when the optional -w switch
was also used. But, it should never have exceeded 512.

This patch ensures the upper limit is always observed.

80e6783436 top: modest efficiency change to message line handling
When the final solution for cursor positioning for all
^Z or ^C cases was introduced the revised placement of
message line management introduced with the window mgr
'screen' refactor was retained. Those two commits mean
that a former tgoto was no longer needed when clearing
that msg line or displaying the scroll coordinate msg.

This patch eliminates the tgoto employed by frame_make
while assimilating a now defunct show_scroll function.

764e27a4dd Increase watch interval.
watch would only use an interval of up to 4294 seconds and silently
change to this limit. The 4294 seconds is 2^32/10^6 or how many
microseconds fit into unsigned int.

This change increases the limit to 2^32 seconds which is
approximately 136 years. This should be ok for now. Anything above
the old limit now uses sleep() instead of usleep() which only uses
integers (so 9999.123 seconds will be 9999 seconds)

This bug was first reported in 2006 and included a patch by
Stephen Kratzer. The patch was updated to fit the current source.

46a1356219 top: correct cursor positioning for all ^Z or ^C cases
Some more (very obscure) conditions where a suspension
or program end might embed the shell prompt within top
output have been uncovered beyond the 2 already known.

We had already covered some suspend/end contingencies:
1. the users were using the 'fields management' screen
2. the users were prompted for any line oriented input

However, there remained some situations where ^Z or ^C
could still produce a misplaced cursor + shell prompt:
3. the 'g' command while waiting for the window choice
4. the 'W' command if about to overwrite an old rcfile
5. the '=' command when exploiting the Inspect feature
6. the period during which any error message was shown

But, even when all those bases are covered there still
remains a remote possibility that such interrupts will
occur during a top repaint cycle. So rather than throw
yet more code at these self-inflicted problems perhaps
it is better if we just throw in the proverbial towel.

Thus, I'll take the only sane approach and restore the
results expected ever since top's inception and before
scrollback buffers entered the picture. Namely, with a
^Z or ^C the cursor will be placed on the final screen
row. That usually means it will immediately follow the
last output line but it may follow many blank lines if
the user interrupts top when *not* on the main screen.

26ae657950 pwdx: fails when run in a nonexistent locale
pwdx rather mysteriously fails with "invalid process id" when run in a
nonexistent locale (e.g. "LC_ALL=foo pwdx $$").  This is because it
fails to obey the documented calling sequence for strtol - that is, set
errno to 0 before the call - and thus the errno from the setlocale
failure bleeds over into its check for whether strtol failed.

This commit extends that ability to embrace line input

5c974ff44d top: enable screen contents preservation at end-of-job
The title of this commit is actually quite misleading.

Were it more accurate, it would at least mention a tty
emulator's scrollback buffer, which was the cumulation
of a long pursuit to reduce the SIGWINCH overhead when
a window manager carelessly floods an application with
that signal *while* a user is still resizing a window!

Disabling and enabling that scrollback buffer resulted
in the final top display replaced with original screen
contents, a phenomenon acknowledged at the time but it
also represented a user interface change which has now
produced the first request for return to old behavior.

After the SIGWINCH dust settled, another problem arose
regarding behaviors under the 'screen' window manager.
In response, top was refactored a bit to avoid display
corruption. That was before discovering 'screen' could
duplicate the scrollback buffer behavior top expected.

As it turns out, the 'screen' refactoring had probably
made scrollback buffer manipulation unnecessary. Still
one could argue that a window should not be allowed to
scroll while a constantly updating program was active.

The solution represented in this commit returns former
behavior at program end (retaining top's last screen).
And if we ever wish to disable scrollback buffers, the
associated logic was retained but made conditional. It
is not reflected in configure.ac but might be someday.

Lastly, this commit corrects cursor positioning when a
^C is issued under 'Fields Management' at any terminal
that didn't have a scrollback buffer (i.e. a console).

ce5e995921 library: for atexit() support, fix fileutils for EPIPE
When fileutils with stream error checking was borrowed
from GNU lib, an omission was also propagated where an
errno of EPIPE wouldn't be preserved in close_stream()
making a test for EPIPE in close_stdout() meaningless.

This patch corrects such oversight so that an errno of
EPIPE no longer produces 'write error' at program end.

( gnulib provides for optionally ignoring EPIPE, but )
( if a program chooses to ignore it, then their code )
( appears to suffer from this close_stream oversight )

b55f9b97db top: add the major version to dlopen of libnuma soname
When the plug-in approach to NUMA support was added, I
carelessly employed the compile-time linker convention
for naming the library. Technically this then required
the 'devel' package for NUMA support to be present for
the unqualified soname symlink to be available. Either
that or one must have manually created such a symlink.

This commit adds the missing major version to dlopen()
of libnuma.so.1 so simply having a more likely package
such as 'numactl' will enable both '2' & '3' commands.

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.

2ede50902f top: provide a build option to change memory precision
When summary & task area memory scaling was introduced
in release 3.3.6, the memory field widths were widened
slightly so unscaled KiB values could be provided more
consistently and scaled values (beyond MiB) could show
3 decimal places of precision. However, some users may
prefer the former widths/precisions for memory fields.

This commit will provide a build time configure option
to return top to those former defaults as a compliment
to a new %CPU & %MEM field precision configure option.

77abe18d01 top: revert %CPU and %MEM precision to former defaults
When summary & task area memory scaling was introduced
in release 3.3.6, the percentage columns were expanded
to provide 3 decimal places of precision. In hindsight
that may have been overkill, making those columns more
of a distraction than useful, with just too much info.

This patch will revert those columns to the former one
decimal place. And as was true, that decimal point may
be sacrificed depending on the number of cpus present.

And, in case anyone might prefer additional precision,
a build option can provide it (--enable-wide-percent).

a6c7923106 Fix btime handling reading from /proc/stat
Function getbtime() currently makes the assumption that btime==0 equals
btime not being present in /proc/stat. This is not quite accurate, as
timestamp 0 is, in fact, also a valid time (Epoch), and /proc/stat may
report it as such.

We introduce a flag to indicate whether btime was found in /proc/stat.
In this way, btime==0 becomes a valid case, provided /proc/stat
actually reports this as the boot time.

procps can still detect the case of btime actually not being reported
by the kernel.

edba932a7e top: introduce a plug-in approach for the NUMA support
The NUMA/Nodes support in top has gone through several
evolutions (primarily dealing with build-sys options).
With this commit the library dependency issues are now
moot and the responsibilities for run-time loading and
dynamic linking are assumed by the top program itself.

Henceforth, if top is executed in an environment where
libnuma.so is present, top will offer such extensions.
Even more importantly, when a missing libnuma is later
installed, top will offer numa support auto-magically.
All NUMA/Node build-sys dependencies are thus removed.

The former NUMA_ENABLED define has become NUMA_DISABLE
should anyone wish to test user interface implications
in an environment that *does* have libnuma. It is also
represented as the ./configure option: --disable-numa.

Lastly, the 't' (View_STATES) toggle will be forced on
for sanity whenever the '1', '2' or '3' keys are used.

Oh that poor ol' build system. With this patch it will
have gone through three separate incarnations in terms
of NUMA/Node support. Those 3 iterations consisted of:

1. A 'porridge too hot' where the top numa support was
enabled if it was built in the presence of libnuma and
the numa.h header. But if the numa library wasn't part
of core packages, that would have broken poor old top.

2. A 'porridge too cold' where numa support was off by
default and must have been explicitly enabled when the
./configure script was run. This could have meant that
distros might not distribute a numa-aware procps, even
though their numa library would have been distributed.

3. And this 'porridge' where the top numa support will
become a 'plug-in' feature activated when the presence
of libnuma.so can be verified at runtime. We'll do our
own loading and symbol resolution (with some help from
dlopen in libdl). Thus maintainers' responsibility for
enabling numa support and then satisfying that library
dependency is now an entirely optional --disable-numa.

As Goldilocks might say about our current configure.ac
"Ummm, I think this porridge tastes just about right".

7b50c2e918 ps: possibility to display seat for a process
Library systemd-login offers possibility to display
name of seat for a session on multi-seat systems.

This patch adds output option "sd_seat" which will
show name of seat or "-", when name of seat can not
be determined, but "seat0" should always exist.

To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.

38e8087d55 ps: possibility to display systemd user unit for a process
Library systemd-login offers possibility to display
name of systemd user unit for specific pid. Note that not all
processes are part of a user unit.

This patch adds output option "sd_uunit" which will
show name of user unit or "-", when process does not belong
to any user unit. This is similar to "sd_unit" but applies
to user units instead of system units.

To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.

Library systemd-login offers possibility to display
the name of the VM or container which process belongs to.

This patch adds output option "sd_machine" which will
show machine name or "-" when the name can not be determined.

To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.

785776c10d ps: possibility to display uid of session owner for a process
Library systemd-login offers possibility to display the Unix
user identifier of the owner of the session of a process.
This information will also be displayed for user processes which
are shared between multiple login sessions of the same user,
where sd_session will be blank.

This patch adds output option "sd_ouid" which will show
user UID or "-", when there is no owner for a process.

To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
