All calls to ScreenManager_new always pass the same first
five values, the orientation is always HORIZONTAL and the
y1 parameter is always the height of the passed-in header
struct pointer. I think its safe to assert at this point
that no VERTICAL orientation will arrive (if it does, its
no harm in re-adding this then) - so we can remove unused
conditionals (and TODOs) based on orientation too.
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.
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.
The (this_) token was not expanded properly, but the bug was not caught
because all uses of this macro specifies (this_)=this .
Also parenthesize macro tokens to prevent further problems.
* Performance improvements
* Support for splitting CPU meters into two or four columns
(thanks to Wim Heirman)
* Switch from PLPA, which is now deprecated, to HWLOC.
* Bring back support for native Linux sched_setaffinity,
so we don't have to use HWLOC where we don't need to.
* Support for typing in user names and column fields in selection panels.
