Commit d8dfbbd3 ("Tidy up process state handling") did change the
highlighting of the UNINTERRUPTIBLE_WAIT state (D) from red to gray.
As this state might means the process probably still has work to do and
can hint at bottlenecks, revert this particular change.
Fixes: d8dfbbd3 ("Tidy up process state handling")
Do not underflow count at the last iteration, which triggers UBSAN when
using -fsanitize=unsigned-integer-overflow. This is useful as those
underflows can be a result of a flawed counting logic (e.g. a counter
gets reduced more than increased).
When we close the application using the quit function F10, the last line
is cleared so that on terminals which do not support ALTBUF the last
line is not clobbered. This do not happen when the application exits as
a result of a signal (SIGINT,SIGTERM,SIGQUIT).
Move the logic to clear the last line into the CRT_done function. This
ensures that it will be executed when the CRT_handleSIGTERM is called.
Use PF_KTHREAD flag in /proc/[pid]/stat to detect kernel threads.
This fixed an issue when a process's cmdline is empty, htop think
it is a kernel thread.
This ensures the initial read of the data is not misinterpreted as arbitrarily large values.
Also this forces the maximum update interval between two subsequent reads to within 30s.
Fixes#860
While most Unix-like systems use 16-bit user IDs,
Linux supports 32-bit UIDs since version 2.6.
UIDs above 65535 are used for UID namespacing of containers,
where a container has its own set of 16-bit user IDs.
Processes in such containers will have (much) larger UIDs than 65535.
Because the current format strings for `ST_UID` and `USER`
are `%5d` and `%9d` respectively, processes with such UIDs
lead to misaligned columns.
Dynamically scale the `ST_UID` column and increase the size of `USER`
to 10 characters (length of UINT32_MAX) to ensure that the user ID always fits.
Additionally: clean up how the titlebuffer size calculation and ensure
the PID column has a minimum size of 5.
Limit the maximum width (instead of only the minimum width), pad the
header width accordingly, and also remove extra stray spaces from the
format string (the main spacing should just come from the alignment of
the value).
Fixes#850.
The names array is terminated by a NULL entry, thus allocate space for
one more than entries.
Fixes: #844
