Implements the suggestion from https://github.com/htop-dev/htop/issues/399#issuecomment-747861013
Thanks to the refactors from 0bd5c8fb5da and 6393baa74e5, this was really easy
and clean to do.
It maintains the "Tree view always by PID" option in the Settings, which
results in some specific behaviors such as "clicking on the column header to
exit tree view" and "picking a new sort order to exit tree view", for the sake
of the muscle memory of long time htop users. :)
RichString_writeFrom takes a top spot during performance analysis due to the
calls to mbstowcs() and iswprint().
Most of the time we know in advance that we are only going to print regular
ASCII characters.
Generic data, as CPU and memory usage, are used by Meters.
In paused mode they would stop receiving updates and especially Graph
Meters would stop showing continuous data.
Improves: #214Closes: #253
- Move swap() macro to source file and implement as function
- Implement Vector_get() and Vector_size() as inline functions
to make them type safe and avoid lhs usage
- Comment comparison statistics, they are only needed for performance
testing
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.
Fixes#688, the bug regressed on 584a9bc.
On Mac OS X 10.11.6, all processes have their parents since there's a
special process named "kernel_task", whose PID and PPID are 0. As a
result, `this->processes` is never changed causing infinite `while`.
This simplifies the protocol between the platform-independent
and platform-specific parts. The platform-specific parts
were supposed to re-determine the value of process->show
on each iteration, and the Darwin subsystem wasn't doing that.
Instead of adding the code to the Darwin part, I lifted the
burden of the OS-specific of resetting process->show: now
they can choose to hide a process if they want to (e.g.
detecting kernel threads) but are not required to
(e.g. on Darwin where we're not listing threads separately (yet?)).
Fixes tree view collapsing/expanding on OSX. Closes#416.
