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.
Enough memory is allocated.
Header.c: In function ‘Header_readMeterName’:
Header.c:157:4: error: ‘strncpy’ specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
157 | strncpy(name, Meter_name(meter), nameLen);
| ^
Header.c:154:18: note: length computed here
154 | int nameLen = strlen(Meter_name(meter));
| ^
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.
* size_t nmemb (number of elements) first, then size_t size
* do not assume char is size 1 but use sizeof()
* allocate for char, not pointer to char (found by Michael McConville,
fixes#261)
* 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.
disable useless code in release builds such as runtime type-checking on
dynamic data structures and process fields that are not being computed,
faster(?) method for verifying the process owner (still need to ensure
correctness), don't destroy and create process objects for hidden kernel
threads over and over. Phew. I shouldn't be doing all this today, but I
could not resist.
