* test/lisp/proced-tests.el (proced--cpu-at-point): New function.
(proced--assert-process-valid-cpu-refinement)
(proced-refine-test, proced-refine-with-update-test): If %CPU for any
process visited is a NaN skip the test.
(proced-update-preserves-pid-at-point-test): Fix typo in comment.
(proced--assert-process-valid-cpu-refinement-explainer): Add process
attributes to the explainer along with tweaking how the process %CPU is
obtained to account for circumstances where it's not numeric (most
notably '-nan').
* test/lisp/proced-tests.el
(proced--assert-process-valid-cpu-refinement-explainer): New function
for explaining refinement test failures in greater detail.
* test/lisp/proced-tests.el (proced-refine-test)
(proced-refine-with-update-test): Use the much simpler CPU refinement
for testing 'proced-refine'. The previous tests made the incorrect
assumption that refining on the PID of process A only filtered the
buffer to contain process A and its children, whereas in actuality
the children of process A's children, their children, and so on will
also be shown.
(proced-update-preserves-pid-at-point-test): Mark as unstable.
* test/lisp/proced-tests.el (proced-refine-test)
(proced-refine-with-update-test): Also check if the parent
process id of each process matches the process id refined
on before failing, since the refiner for process id returns
the children of a process in addition to the process itself.
(Bug#64800)
Fix unstable proced test by omitting the revert parameter in
'proced-update'. This was caused by the process being refined on
exiting between the initial 'proced' call and the successive
'proced-update' call. This resulted in proced skipping the refinement
in 'proced-update', causing all processes to be shown again and the
test to fail.
* test/lisp/proced-tests.el (proced-refine-with-update-test): Do not
use revert parameter when calling 'proced-update'.
Preserve the window position for windows which display a proced
buffer, but are not the selected window when a proced buffer is
updated. Previously, the window position would be set to the
start of the buffer when a proced buffer was updated and it was
not displayed in the selected window.
Similarly, preserve the position in proced buffers which are not
displayed in any window by setting
'switch-to-buffer-preserve-window-point' to nil in proced buffers.
* lisp/proced.el (proced-auto-update-timer): Only update a given
proced buffer if it is displayed in a window.
(proced-update): Set the window position if the proced buffer is
displayed in a window.
(proced--position-info, proced--determine-pos): New Functions.
(proced-mode): Set 'switch-to-buffer-preserve-window-point' to
nil in proced buffers.
* test/lisp/proced-tests.el
(proced-update-preserves-pid-at-point-test): New test.
* test/lisp/proced-tests.el (proced-format-test)
(proced-update-test, proced-revert-test, proced-color-test):
Remove the 'skip-unless' condition, as it is unnecessary.
(proced-refine-test, proced-refine-with-update-test): Use PID, not
Args, as the column to test, as PID is more portable.
