Nathan Scott c5808c56db Consolidate repeated macro definitions into one header
The MIN, MAX, CLAMP, MINIMUM, and MAXIMUM macros appear
throughout the codebase with many re-definitions.  Make
a single copy of each in a common header file, and use
the BSD variants of MINIMUM/MAXIMUM due to conflicts in
the system <sys/param.h> headers.

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.

Arnavion 81b64691a7 Move sysfs-reading code to LinuxProcessList.c and add average frequency.
This way the frequency is read from sysfs only once per update cycle
instead of every time the UI is redrawn.

This also changes the code to read from /proc/cpuinfo instead. This is because
reading from scaling_cur_freq stalls for 10ms if the previous read for the file
was more than one second ago. [1] Since htop's update cycle is
longer than that, it would cause the read of each CPU's scaling_cur_freq file
to block the UI for 20ms. This easily led to a noticeable half-second lag on
a 20+ CPU machine.

/proc/cpuinfo also has a 10ms delay, but this applies for the whole file
so the delay does not scale with the number of CPUs. [2]

Arnavion 9703a25d1b Divide by 1000, not 1024, and show more decimals. 2019-08-09 23:22:05 -07:00
Arnavion 4b0600d8f8 Add new display option to also show CPU frequency in CPU meters.
The option is only implemented on Linux. On other platforms, and on Linuxes
that do not expose the relevant sysfs file, the frequency will be 0.

The "CPU average" meter does not show a frequency, only
the individual per-CPU meters.

Tomasz Kramkowski 2b5c1b4b13 Replace all uses of sprintf with snprintf
In all the cases where sprintf was being used within htop, snprintf
could have been used. This patch replaces all uses of sprintf with
snprintf which makes sure that if a buffer is too small to hold the
resulting string, the string is simply cut short instead of causing
a buffer overflow which leads to undefined behaviour.

`sizeof(variable)` was used in these cases, as opposed to `sizeof
variable` which is my personal preference because `sizeof(variable)`
was already used in one way or another in other parts of the code.

Explorer09 9dea20e068 Rename Meter.setValues() functions to updateValues()
Rationale (copied from htop issue #471):
The function name "setValues" is misleading. For most OOP (object-
oriented programming) contexts, setXXX functions mean they will change
some member variables of an object into something specified in
function arguments. But in the *Meter_setValues() case, the new values
are not from the arguments, but from a hard-coded source. The caller
is not supposed to change the values[] to anything it likes, but
rather to "update" the values from the source. Hence, updateValues is
a better name for this family of functions.

Explorer09 99fb3070a2 Explicit "maxItems" property of meters
Two changes in this commit:
- All meters now explicitly specify "maxItems" property, even for just
  1 item. (Exception is "container" CPU meter classes, which use
  CUSTOM_METERMODE.)
- "maxItems" being 0 is now allowed. This will let bar meters and graph
  meters render an empty meter.
