cbbe8fe324 top: ensure an EXIT_FAILURE with bad command line args
When getopt usage was added (plus long options) in the
patch shown below, top no longer returned EXIT_FAILURE
when the error message was generated by getopt itself.

This commit will restore the proper behavior no matter
who might issue a command line argument error message.

Thanks to Bastian Bittorf for discovering this buglet.

133a833942 library: become more tolerant of /proc/cpuinfo formats
In the issue referenced below, it is now apparent that
not all architectures follow a logical/expected format
for the /proc/cpuinfo file. Specifically, the expected
empty line after each processor entry might be missing
under some architectures for the last processor shown.

[ and a belated review of kernel source confirms it. ]

So this commit makes our stat module a little bit more
tolerant of some potential missing newline characters.

[ along the way, it's also now tolerant of a missing ]
[ cpuinfo file plus more efficient whenever a cpu is ]
[ is not linked to a core or toggled offline/online. ]

8c81808de0 pgrep: Use only --signal option for signal
When pgrep was used to match on signal, it makes sense to use
the same signal parsing code as pkill. Unfortunately the
"find the signal" part is a little too enthusaistic about what a
signal is, meaning

pgrep -u -42

fails because the signal becomes "42" and then there is no UID.

This is a bit sad for pkill but has been that way for a long
time. For pgrep this is new so now only the long form
pgrep --signal <X>
will work.

In addition, when using --signal if pgrep/pkill couldn't work
out what the signal was it just silently ignored it. It now
complains and aborts.

2532b5d2dd ps: Add configurable date format for lstart field
The lstart field has been converted to use the strftime()
function so that it uses the locale. A new option -D
allows the user to define the format that would want this
field to show.

This may mean the field will be longer than it should be,
especially for French locales and the user defined field,
but the field length can be specified too.

---

This commit started off making all the relevant fields use the
locale correctly so it could solve #226 as well. The issue
is there an implied restriction (or not) around
strftime("%b") and probably strftime("%a") for abbrievated month
and day names respectively.

English, and some/most other languages put an additional
restriction that all abbreviations are 3 characters long.
The problem is, not all languages do this.

French is a good example:
janv. févr. mars avril mai juin juil. août sept. oct. nov. déc.

Maybe strip the . at the end?
 That helps for some months, not all
Maybe take the first three characters?
 Several wide languages will have big issues
Maybe convert wide, get wcslen then use that.
 Even after that June "juin" and July "juil" are both "jui".

So, anything that uses the month (bsdstart,start) use ctime which
doesn't use locale. That solves the length issue.

stime does, which means it has this issue but its been like that
for years. You get stuff like this:

janv.13 482261
00:00 1151918
 2022 1458628
06:12 1957584

The only way to fix that would be to
 a)Make the field two characters longer
 b)Convert it back to ctime() which means everyone else
   loses.

This could have be oh-so easy if everyone made %b and %a three
(wide) characters everywhere.

Fix conversion errors due to precision issues in function unitConvert

Because we do (unsigned long)(float)98720620 in function unitConvert
and this is wrong! We should do (unsigned long)(double)98720620 here.

8a65a304e0 watch: Fix buggy line-deletion behaviour with --no-linewrap
This change is largely based upon Justin's patch, I just moved the
reset_ansi() parts out otherwise you get strange colour reset
behaviours.

Original patch message:
I used the --no-linewrap (-w) option for the first time today, watching
some wide output that didn't quite fit in my tmux pane. Quickly I
noticed a problem: while --no-linewrap did indeed eliminate the
spillover of lines too long for the terminal "window" width, it *also*
resulted in a bunch of lines from the program output being hidden
entirely.

After some fiddling around, the exact problematic behavior appears to be
as follows:
 1. Lines which would have wrapped (more than $COLUMNS chars long) are
    handled correctly.
 2. Lines which would *not* have wrapped (shorter than $COLUMNS) are
    printed; but then the next line is *not* printed! For long sequences
    of non-wrap-length lines, you get an every-other-line-is-visible
    sort of effect.

The logic underlying the problem seems to be this: in the run_command
loop, if the x loop goes all the way to completion (meaning we've
reached the right-side edge of the window area), there's a small block
of code for --no-linewrap whose main purpose is to call find_eol, which
eats input until it hits a newline (or EOF). Clearly this is intended to
be done for lines that are too long, so that the excess characters are
discarded and the input pointer is ready to go for the subsequent line.

However, this code isn't in any way conditional on the value of eolseen!
Short/wouldn't-wrap lines will have encountered a newline character
before exhausting the entire x loop, and therefore eolseen will be true.
Long/would-wrap lines will not have encountered a newline when the x
loop is exhausted, and so eolseen will be false.

Nevertheless, find_eol is called in *both* cases. For long lines, it
does what it's meant to do. For short lines, *the newline has already
been encountered and dealt with*, and so the actual effect of find_eol
is to eat the entirety of the next line, all the way through to its
newline, such that it isn't printed at all.

866abacf88 pgrep: Support matching on the presence of a userspace signal handler
In production we've had several incidents over the years where a process
has a signal handler registered for SIGHUP or one of the SIGUSR signals
which can be used to signal a request to reload configs, rotate log
files, and the like. While this may seem harmless enough, what we've
seen happen repeatedly is something like the following:

1. A process is using SIGHUP/SIGUSR[12] to request some
   application-handled state change -- reloading configs, rotating a log
   file, etc;
2. This kind of request is deprecated and removed, so the signal handler
   is removed. However, a site where the signal might be sent from is
   missed (often logrotate or a service manager);
3. Because the default disposition of these signals is terminal, sooner
   or later these applications are going to be sent SIGHUP or similar
   and end up unexpectedly killed.

I know for a fact that we're not the only organisation experiencing
this: in general, signal use is pretty tricky to reason about and safely
remove because of the fairly aggressive SIG_DFL behaviour for some
common signals, especially for SIGHUP which has a particularly ambiguous
meaning. Especially in a large, highly interconnected codebase,
reasoning about signal interactions between system configuration and
applications can be highly complex, and it's inevitable that on occasion
a callsite will be missed.

In some cases the right call to avoid this will be to migrate services
towards other forms of IPC for this purpose, but inevitably there will
be some services which must continue using signals, so we need a safe
way to support them.

This patch adds support for the -H/--require-handler flag, which matches
on processes with a userspace handler present for the signal being sent.

With this flag we can enforce that all SIGHUP reload cases and SIGUSR
equivalents use --require-handler. This effectively mitigates the case
we've seen time and time again where SIGHUP is used to rotate log files
or reload configs, but the sending site is mistakenly left present after
the removal of signal handler, resulting in unintended termination of
the process.

1db14dafd9 top: include the '5' toggle on the primary help screen
When the p/e-cores support (via the '5' key) was added
in the patch referenced below, I intentionally omitted
that key from the top primary help screen. This seemed
appropriate since it only applied to select Intel cpus
and, besides, that screen was getting kind of crowded.

[ it remains an objective to fit on a 80x24 terminal ]

Upon reflection, I found a way to squeeze it into that
help screen and have decided to included it. Hopefully
its presence will encourage use of top's new provision
on any Intel platforms that distinguish between cores.

In the commits referenced below special code was added
to make the bottom window sticky and fix the bug after
'Cap_nl_clreos' was traded for the 'Cap_clr_eol' loop.

However, there's always major overhead associated with
interacting with a terminal. So we'll only abandon the
single 'Cap_nl_clreos' putp in favor of repeated calls
with 'Cap_clr_eol' when a bottom window isn't present.
