Christian Göttsche 89473cc9ae Rework enum ProcessField 
Use only one enum instead of a global and a platform specific one.
Drop Platform_numberOfFields global variable.
Set known size of Process_fields array

Benny Baumann 77db240b48 Split boilerplate and platform-independent field comparison 
This acheives two things:
- Allows for simple tie-breaking if values compare equal (needed to make sorting the tree-view stable)
- Allows for platform-dependent overriding of the sort-order for specific fields

Also fixes a small oversight on DragonFlyBSD when default-sorting.

Hisham Muhammad 3d1703f16f Invert Process_compare resolution so that superclass matches run first 
* This removes duplicated code that adjusts the sort direction from every
  OS-specific folder.
* Most fields in a regular htop screen are OS-independent, so trying
  Process_compare first and only falling back to the OS-specific
  compareByKey function if it's an OS-specific field makes sense.
* This will allow us to override the sortKey in a global way without having
  to edit each OS-specific file.

Nathan Scott 75e9f9a8d9 Cull the definitions of pageSize and pageSizeKB from CRT.c 
By storing the per-process m_resident and m_virt values in the form
htop wants to display them in (KB, not pages), we no longer need to
have definitions of pageSize and pageSizeKB in the common CRT code.

These variables were never really CRT (i.e. display) related in the
first place.  It turns out the darwin platform code doesn't need to
use these at all (the process values are extracted from the kernel
in bytes not pages) and the other platforms can each use their own
local pagesize variables, in more appropriate locations.

Some platforms were actually already doing this, so this change is
removing duplication of logic and variables there.

Christian Göttsche 157086e750 Split RichString_(append|appendn|write) into wide and ascii 
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.

Christian Göttsche 4c4ba9d949 DragonFlyBSDProcessList: fix missing type 2020-12-06 00:43:41 +01:00
Nathan Scott f704baeb82 Drop unused global ProcessList memory fields 
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

Nathan Scott c75c5ef9c6 Minor cleanups to platform-specific init and done 
Move platform-specific code out of the htop.c main function
and into the platform sub-directories - primarily this is
the Linux procfs path check and sensors setup/teardown; not
needed on any other platforms.  No functional changes here.

Christian Göttsche 397b5c4bd0 Introduce spaceship comparison for Processes 
If currently two unsigned values are compared via `a - b`, in the case b
is actually bigger than a, the result will not be an negative number (as
-1 is expected) but a huge positive number as the subtraction is an
unsigned subtraction.

Avoid over-/underflow affected operations; use comparisons.
Modern compilers will generate sane code, like:
    xor     eax, eax
    cmp     rdi, rsi
    seta    al
    sbb     eax, 0
    ret

Christian Göttsche 96e2a4259e Continue to update generic data in paused mode

In paused mode they would stop receiving updates and especially Graph
Meters would stop showing continuous data.

multi 9ee72568dc CPUMeter: add octuple-column CPU meters.

Zev Weiss a1a027b9bd Axe automated header generation. 
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.
