Christian Göttsche 436808ff99 Use RichString_appendnAscii where possible
`RichString_appendnAscii()` avoids a `strlen(3)` call over
` RichString_appendAscii()`.
Use the former where the length is available from a previous checked
`snprintf(3)` call.

Keep `RichString_appendAscii()` when passing a string literal and
rely on compilers to optimize the `strlen(3)` call away.

Stuart Henderson feec16cbb5 don't include offline CPUs in summary for OpenBSD
By default, OpenBSD disables SMT (hyperthreading) cpu pseudo-cores.
This can be changed at runtime by setting the hw.smt sysctl so they
may become active later, therefore they are still present in cpu
stat structures but are marked as offline.

As done with native top(1), this drops them from the cpu summary
graphs.

* Use devname(3) on BSD derivate to show the actual terminal,

Nathan Scott 356488aa53 Request the realtime and monotonic clock times once per sample
Refactor the sample time code to make one call to gettimeofday
(aka the realtime clock in clock_gettime, when available) and
one to the monotonic clock.  Stores each in more appropriately
named ProcessList fields for ready access when needed.  Every
platform gets the opportunity to provide their own clock code,
and the existing Mac OS X specific code is moved below darwin
instead of in Compat.

A couple of leftover time(2) calls are converted to use these
ProcessList fields as well, instead of yet again sampling the
system clock.

Sohaib 421bdeec60 Merging all the points related to calculating time in one place
The end goal is to consolidate all the points in htop that can only work in
live-only mode today, so that will be able to inject PCP archive mode and have
a chance at it working.
The biggest problem we've got at this moment is all the places that are
independently asking the kernel to 'give me the time right now'.
Each of those needs to be audited and ultimately changed to allow platforms to
manage their own idea of time.
So, all the calls to gettimeofday(2) and time(2) are potential problems.
Ultimately I want to get these down to just one or two.

Christian Göttsche 8163b8164f TaskMeter: always show number of threads
Always show the number of kernel and userland threads, even when they
are disabled to not be shown in the process list.

The data is already available and might improve understanding the system
utilization.

Use a shadow color in case the kind of thread is hidden, else the normal
meter one.

Abstract htop main function to allow for a platform binary
2021-03-25 15:57:15 +11:00
Nathan Scott 36389fb0da Abstract htop main function to allow for a platform binary
One review request relating to the PCP platform is to have
a clearly separate binary from the regular htop so that we
have no confusion as to what is being requested to run, to
aid debugging, and a bunch of other good reasons.

This commit renames htop.c to CommandLine.c and provides a
minimal htop main function for 'native' platforms to use.
The PCP version of this will setup libpcp.so and then call
the same CommandLine_run function as regular htop.

Nathan Scott 0ada9f325f Move libcap use to (Linux) platform-specific code
The libcap code is Linux-specific so move it all below
the linux/ platform subdirectory.  As this feature has
custom command-line long options I provide a mechanism
whereby each platform can add custom long options that
augment the main htop options.  We'll make use this of
this with the pcp/ platform in due course to implement
the --host and --archive options there.

Benny Baumann 57e0ce7b4f Use `#if defined()` syntax when `#elif defined()` is present
This prefers the `#if defined()` syntax over the `#ifdef` variant
whenever there's also a `#elif defined()` clause, thus making the
multiple branching structure more obvious and the overall use
more consistent.
