As the sysvinit becomes obsolete, some of the bundled tools
need to find a new home. The procps-ng project seems to be
the most suitable project for adopting the pidof tool.
This commit introduces a redesigned version of pidof
that satisfies the LSB requirements.
In corner cases the behaviour might differ from the former
one as the new version doesn't use any stat(2) calls.
The automake AM_SILENT_RULES macro is supported since automake 1.11
(which is required for procps). The silent functionality is enabled by
default, you can change it by:
./configure --disable-silent-rules
or
make V=1
Note that make still prints compiler errors, etc.

Previously the libselinux support was present
in the sources, but disabled with a preprocessor
condition (#if 0).
From now the libselinux support can be enabled with
the --enable-libselinux switch available
in the configuration script. That way is more
flexible than local patches modifying the condition
value from 0 to 1.
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.

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).

The earlier commit purporting to allow top to be built
in the absence of that dynamic linking library stopped
just a little short of the truth. So this will fix it.

Been a while since we ran a re-scan over the autotools files. This
change modernises the configure file. Not a great deal of changes
required to bring us up to date, autoscan doesn't understand our
optional things, which is fine.
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".

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.
Library systemd-login offers possibility to display
name of a systemd unit file for specific pid. Note that
not all processes are part of a system unit/service

This patch adds output option "sd_unit" which will
show name of systemd unit or "-", when process does not
belong to any unit.

This patch provides the build system support for those
top extensions dealing with the NUMA summary displays.

For portability, check for error.h during configure and define
HAVE_ERROR_H accordingly.
If this header is not available, emulate the functionality of error()
from glibc with an inline wrapper in include/c.h.
For portability, check for stdio_ext.h during configure and define
HAVE_STDIO_EXT_H accordingly.
If the current system does not provide this header, use a fallback for
__fpending(). This definition will not work on all systems as it relies
on internal data structures of libc. A more portable solution should be
preferred, for example by using gnulib.
For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.
The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.
Fixes the following error in configure stage.
configure: error: cannot run test program while cross compiling

The newer tools/ subdirectory shares a common prefix
with the previously existing top/ subdirectory and
thereby hinders shell command completion.
There was already a minor conflict between testsuite/

The library used to be called libprocps but it was renamed to make sure
there was only one. However the formatting of the library SONAME has
changed so there cannot be any confusion.
libprocps makes it clear that its a library from this project and not a
set of functions directly on the filesystem.
The patch also removes fixed size of input, which can be problematic.
I do not know how long the string `yes' might be in all of the worlds
languages.

The utility library is for functions which are shared in commands,
but that does not belong to libproc-ng. The first function is a
wrapper for strtol that performs error checking, and exists if such
happen.

. 1 program uses curses (top)
. 2 programs use ncurses (slabtop, watch)
. all 3 include non-wide <curses.h> or <ncurses.h>
. those 3 do not currently need wide support
. but anticipating nls, we link against libncursesw
This patch ensures an environment consistent with current
and future ncurses needs.
Slackware seems to have this patch, while it is not in use(?) Well,
the upstream procps-ng allows one to disable warnings if that is
wanted. After all having this sort of 'feature' does not cost much,
while lacking it might annoy someone.

Previously the version of libproc always tracked the version of procps.
This doesn't work when other non-procps programs link to the library as
they are always playing catch up.
This change makes the library version independent of the procps version.
It will only be incremented when needed.
procps works well on Linux, on other arches there are some strange
differences due to their emulation of procfs which is not 100%
Disabling checks for non-linux until that can be sorted out.
