Crest is a 'top/ps' like application. Forked from https://openrepos.net/content/miska/crest
As of version 1.8.1, Crest will no longer use the external 'ps' command, but gather this process info itself.
The default view is apps only. But what defines an app? Crest simple used to filter names like "harbour-", "jolla-" or processes with dots. Lighthouse also has an app view, but filters app names found in /usr/share/applications.
Crest now also matches the desktop files in /usr/share/applications and ~/.local/share/applications, but also includes sailfish-qml apps/processes (which seems more accurate than the old method Crest used).
In "Show all processes" mode Crest does not show the processes that appear between brackets; processes that do not have an associated command line (mostly kernel threads and some system services). They do not display memory usage, but can use CPU power. Not showing these processes shortens the process list a lot.
If "Incl. no cmdline [top 60]" is actived, those processes are also shown. To shorten the list and prevent higher cpu load, the list is limited to the top 60 entries.
RSS vs PSS
Crest shows the resident set size (RSS). It is less accurate than proportional set size (PSS), as PSS handles used shared memory use better. The downside of PSS is that you need to have privileged access to collect that info.
Colors used for procesname
nemo/defaultuser = Theme.secondaryColor
root = Theme.primaryColor
others (android, media, system etc.) = Theme.secondaryHighlightColor
License to kill
Running as nemo/defaultuser, you can only kill your own processes.
But when /usr/bin/sudo is located and does not ask for a password, it will use that when needed (assuming sudo is configured correctly, else it fails of course), so root and android processes can be terminated as well. Needless to say killing random processes can make your system unstable or even crash.
