The commit referenced below forced a return to row one
whenever there was a thread mode transition. Now, with
our new focus ('F') feature, we should adopt a similar
philosophy so as to avoid potential display anomalies.

The commit shown below introduced two abreast printing
for %Cpu statistics. But, the Memory & Swap lines have
always been printed on separate lines when '4' was on.
With this commit, those lines will now be treated just
like %Cpu stats, either separate lines or two abreast.

Signed-off-by: Jim Warner <james.warner@comcast.net>
When the '4' toggle is on, and Summary Area %Cpu lines
are shown two abreast, it's not always clear where the
separation is between the two processors. So with this
patch we'll now print a vertical bar separator between
them (looking similar to the existing field headings).
We will also reduce that 'GRAPH_suffix' constant to 1,
reflecting the the trailing ']' bracket only, so as to
maximize top's exploitation of available screen width.

Just to see if I could, the new #define will force the
indentation of a parent task to be reset to zero while
maintaining the proper child indentation relationship.
Signed-off-by: Jim Warner <james.warner@comcast.net>
Sometimes, it might be useful to isolate a parent task
and its forked children from other system activity. As
an example, a user might want to examine workload in a
specific lxc container. Or maybe there is some need to
question what's happening under the same tmux session.
Since forest view mode tends to be a relatively stable
display, it will sometimes satisfy the above need. But
that mode can't currently guarantee the target process
always remains as the topmost task or even is visible.
So, this patch will enable focusing on any parent task
and keeping it as the topmost process while displaying
it and its forked children only. It then appears as if
there is no other activity in that system by virtue of
the blank lines which follow that final child process.
To implement this new feature, top's redundant 'F' key
has been repurposed. It made little sense devoting two
keys to the Fields Management screen (especially since
the key we've taken required two separate keystrokes).

commit 0bf15c004d
Signed-off-by: Jim Warner <james.warner@comcast.net>
In the patch referenced below, 2 potential abends were
fixed both of which involved 'alternate display mode'.
The root cause of those abends was a negative value in
the 'begnext' field for other than the current window.
And while that potential is fixed for now the existing
code almost invites such problems again in the future.
So, this patch will remove any temptation to name some
other window in the 'mkVIZrow1' macro. And, since that
macro is not the only source of 'begnext' changes, the
'mkVizrowX' is being added to identify such occasions.
[ and for symmetry i've added a 'mkVIZyes' macro and ]
[ ameliorated an otherwise surreptitious assignment! ]

Signed-off-by: Jim Warner <james.warner@comcast.net>
- Simplify control flow a bit. We don't need two loop variables, either.
- Consistently use %lld for bytes.
- Fix the base handling for human-readable output. The code used to
calculate *mebibytes* first, then scale that to the required exponent
with the selected base, which is patently wrong.
Fixes https://gitlab.com/procps-ng/procps/-/issues/133
This commit will address potential abends upon leaving
the windows help or color mapping screens and invoking
alternate display mode ('A'). It only happens if that
current window was changed with multiple 'a'/'w' keys.
So now, rather than leaving a trail of negative values
in the 'begtask' field, compliments of that win_select
function, we'll remove the mkVIZrow1 macro. Henceforth
it will be issued just once per user interaction. Thus
a promise of 'Curwin' only being impacted is restored.

in include/c.h we check if HAVE___PROGNAME is defined, but the
corresponding macro for setting (or not setting) it is missing from
the configure script. This commit adds the missing macro, by
copying it from the macro in tmux.
When top calls malloc, if a signal is received, it will
call sig_endpgm to process the signal. In the bye_bye function, if the
-b option is enable, the Batch variable is set, the fputs function
will calls malloc at the same time. The malloc function is not reentrant, so
it will cause the program to crash.

Sometimes the testing sequence would leave a source tree
under procps-ng-(version) which, if update-potfiles was
run, would include these temporary files in the list, causing issues
later.
The script now explicitly ignores those temporary files.
Since this master library isn't quite as sophisticated
as the newlib version, this patch will protect against
the possibility of multibyte characters in a program's
name combined with some locale without UTF-8 encoding.

This patch is intended to bring the master branch into
closer alignment with the newlib branch functionality.
The commit shown below replaced that 'escape_str' with
'escaped_copy' so that the ps program wouldn't execute
some code twice. However, it created a problem for the
top program when the UTF-8 encoding was not available.
Unlike ps who calls the escape functions directly, top
outputs those library provided strings unaltered. That
means there is no workaround (like LANG=) when such an
encoding was unavailable. This, in turn, can lead to a
corrupted display (especially with the linux console).
Now, when a UTF-8 encoding is not available, multibyte
chars are converted to '?', reducing display problems.

[ should program names contain multibyte characters. ]

commit eea5626bb1
Signed-off-by: Jim Warner <james.warner@comcast.net>
Now that the ps program is using 'escape_str' for most
of the library's returned strings, this patch tries to
lessen the prospects of executing that function twice.
Our newlib branch has achieved such a goal through the
elimination of nearly all escape.c code. However, here
we avoid API change by trading some 'escape_str' calls
(with wide character overhead) for a slightly extended
'escaped_copy' call (which incurs no multibyte costs).
Note: until we migrate to the newlib version, there is
a remaining call to 'escape_str' which we can't avoid.
Such code involves the 'escape_command' function call.
[ As we prepare for this new (final?) release, there ]
[ were already internal library changes that require ]
[ a new 'revision'. This patch won't impact the API! ]

When any process' command line contains multibyte utf8
characters, two separate display problems could arise.
1. If that COMMAND column is not displayed as the very
last field, then field(s) to the right are misaligned.
2. Even when last, should utf8 string length (not that
display length) exceed allowable screen width, it will
nonetheless suffer from improper premature truncation.
Number 1 is less of a concern since the cmdline column
is likely to always be the last field to be displayed,
if only to enable right and left scrolling provisions.
Number 2 is much more likely to occur, especially with
additional fields which might be shown before COMMAND.
Or, forest view child tasks can yield the same effect.
So, this commit will permit the correct utf8 multibyte
display regardless of field position or string length.
And, we'll bring top into line with the ps program for
additional fields potentially subject to utf8 display.

Form its inception (back in May of 2011), escaped_copy
has always been a flawed function. It does not operate
on 'escaped' strings but instead treats all input as a
regular string incapable of containing utf8 sequences.
As such, it should only be used for strings guaranteed
to NOT contain multibyte characters (like supgid). For
all other strings, which could contain utf8 stuff, the
correct function should have been that escape_str guy.
So this commit changes nearly every escaped_copy call.

Use NULL in format_array to indicate that the print function shall be
used also for sorting. Change sr_nop() to NULL for all fields which
don't use pr_nop() for printing.
Before the commit (note that '--sort label' has no effect: the rows
are not sorted according to label field):
$ ps -A -o command,label --sort label | grep /lib/systemd
/lib/systemd/systemd-journa system_u:system_r:syslogd_t:s0
/lib/systemd/systemd-udevd system_u:system_r:udev_t:s0-s0:c0.c1023
