dbe27d3ad1 Updated configure.ac
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.

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.

5686877cd4 build-sys: eliminate dependencies for the NUMA support
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".

95d0136281 library: dynamic buffer management even more efficient
One recent patch to dynamic buffer management involved
over-allocating the buffer increase to lessen calls to
xrealloc. That was successful, but the actual increase
amount did not attempt to optimize size or alignments.

With this commit, we'll copy an approach recently used
by the top program and round up buffer sizes to 1 KiB.
More importantly, while buffers are quickly reaching a
KiB optimum multiple, no memcpy will ever be employed!

To illustrate just how effective top's algorithm would
be, just change the initial and subsequent allocations
from the current 1024 bytes to just a single byte then
add an fprintf.  Those one byte reallocations while on
the way to optimum buffer size will be a one-time cost
and won't represent any recurring performance penalty.

( gosh, that top program *must be* one fart smeller, )
( or was that a smart feller, i can't remember which )

d16fd8e462 top: snapshot /proc/stat reads to minimize distortions
Almost forever, top has been accessing the /proc/stat/
directory one line at a time until either smp_num_cpus
was reached or (more recently) Screen_rows is reached.

When NUMA/Nodes support is enabled screen rows will no
longer serve as a limit because all cpus must be read.

With this commit, the entire /proc/stat/ directory can
be read at once so all statistics will be frozen. Thus
individual cpus will no longer keep "ticing" until top
gets around to accessing them via some separate fgets.

The distortion this commit eliminates was quite easily
seen when comparing old/new tops using: individual cpu
stats vs. cpu summary; a healthy delay interval of 3-5
seconds; manually synchronized update cycles (the hard
part); some system loading (maybe another top at -d0).

Additionally, this patch eliminates some long standing
unnecessary initialization made possible because of an
allocation via calloc. If some parts are never touched
by sscanf due to a kernel version, it's unnecessary to
repeatedly re-initialize those portions to zero again.

8d989c68c0 top: program code changes, enable NUMA/Node extensions
This commit extends the top Summary Area cpu states to
include information on Non-Uniform Memory Architecture
nodes. It is based upon changes originally proposed by
Lance Shelton who was instrumental in the final patch.

With this change, the user will have new commands that
will provide alternatives to the individual cpu stats:

. '2' toggles between cpu & numa node summary displays
. '3' provides node summary and related cpu statistics

These extensions required some minimal system support.
Typically, the numactl package (and maybe libnuma-dev)
are all that's needed to show a single node which owns
all the processors. Failing that, or for slightly more
variety, top also offers a #define named PRETEND_NUMA.

The change in pmap is necessary if it happens that the whole output of
pmap -X or -XX has been done before the second regexp is matched. Since
the matching is greedy, it is matched by the full output, so that
nothing is left for the third regexp and the test fails with
FAIL: extra extended output (footer).

526bc5dfa9 library: avoid SEGV if file2str should read zero bytes
When utility buffers were introduced for file2str read

such that a read of zero no longer returns a -1 value.

This commit ensures that zero bytes read returns a -1.

And although the solution differs from a merge request

4aa917455c top: fix the bug affecting certain Find/Locate results
When 'Other Filtering' was introduced the idea of what
constituted a displayed row changed. No longer was any
call to task_show assured of consuming one screen row.
Now the determining factor was whether or not the rows
were empty. This worked Ok until a certain Find string
was active then the entire display could be corrupted.

With Find active, the task_show() function alters each
returned row while highlighting each visible match. If
the search was on a single byte value & matched at the
beginning of a row the match got overwritten with '\0'
which then appears empty upon return to window_show().
So that row would not be counted as having been shown.

This was best illustrated with a Find on a single ' '.

This patch will restore proper 'Find/Locate' behavior.

a45dace4b8 library: utility buffers now immune to buffer overflow
A recent Debian bug report, dealing with release 3.2.8
and its even more restrictive buffer sizes (1024) used
in stat, statm and status reads via file2str calls, is
a reminder of what could yet happen to procps-ng. Size
needs are determined by kernel evolution and/or config
options so that bug could resurface even though buffer
size is currently 4 times the old procps-3.2.8 limits.

Those sizes were raised from 1024 to 4096 bytes in the
patch submitted by Eric Dumazet, and referenced below.

This patch makes libprocps immune to future changes in
the amount of stuff that is ultimately found in a proc
'stat', 'statm' or 'status' subdirectory. We now trade
the former static buffer of 4096 bytes for dynamically
allocated buffers whose size can be increased by need.

Even though this change is solely an internal one, and
in no way directly affects the API or the ABI, libtool
suggests that the LIBprocps_REVISION be raised. I hope
Craig remembers to do that just before a next release.

We don't want a repeat of the procps-ng-3.3.4 boo-boo,
but with no API/ABI impact that probably can't happen.

p.s. A big thanks to Jaromir Capik <jcapik@redhat.com>
who reviewed my original version and, of course, found
some of my trademark illogic + unnecessary code. After
his coaxing, he helped make this a much better commit.

If the 'Inspect' feature was used to view a file which

This was also the occasion where valgrind might object

It was a harmless situation and somewhat rare to begin
with. Anyway this commit will eliminate the potential.

Additionally, supporting readfile logic was simplified

field's data has only 4 bytes whereas the header is 5.

Moreover, this created a conflict with the top program
which used that name in a column header already. Plus,
top emitted a 'Translation Hint' that suggests the max
chars should be 8 which is a limit pmap needn't share!

The xgettext program provides no way to keep identical
strings separate. This meant both top and pmap will be
sharing not only the msgid but a Translation Hint too.
So, the solution will now be two distinct field names.

Besides the kernel folks document it as 'perm' anyway!

0c0c543466 pmap: wield my machete, achieve width-wise nls support
The existing gettext nls support in pmap exposed users
to some potentially ugly misalignments should the text
that's used in headers someday actually be translated.

The length issue had been addressed already for -X/-XX
modes, but the column headers weren't nls translatable
as yet. This commit makes any header (not literally in
/proc/#/smaps) nls aware. It provides translated width
protection to all modes except one that's header-less!

As part of this effort, the occasional two spaces that
preceeded the Mapping column have been reduced to one.

3262143a29 pmap: trade inept width approach for printf's built-in
When the new -X/-XX options were introduced, the width
and justification requirements were satisfied with a 2
step approach. First, format strings would dynamically
be built and then employed in the subsequent printf().

This was a total waste of time and resources since the
printf family of functions provide for the '*' width &
precision conventions to meet this need via arguments.

But even more importantly that foolish endeavor always
hides the potential warnings like the one shown below.

Henceforth this pmap will printf in the proper manner!

9db537503d pmap: formatting only changes, for minimum consistency
This patch just adjusts miscellaneous indentation etc.
so we can begin the odious task of addressing the pmap
nls needs with at least a consistently formatted base.

f85439e42d pmap: restore a proper response when arguments missing
Ever since pmap was refactored via the reference below
(and sprinkled with those damn tabs), the response for
the absence of any argument has been an error message.

This patch restores the proper behavior ('usage' text)
and updates the dejagnu 'no arguments' expect pattern.

088d77c3ae pmap: New switches - RC support (-n/-N,-c/C) & ShowPath (-p)
This commit introduces 4 new switches for the RC support
and 1 more switch for toggling the path printing
in the mapping field. the configuration file can be used
for a selection of columns to be displayed and for toggling
the path printing in the mapping field.
