Subject: [PATCH] systemctl: suppress errors with "show" for nonexistent units
|
|
|
c79076 |
and properties
|
|
|
c79076 |
|
|
|
c79076 |
Show is documented to be program-parseable, and printing the warning about
|
|
|
c79076 |
about a non-existent unit, while useful for humans, broke a lot of scripts.
|
|
|
c79076 |
Restore previous behaviour of returning success and printing empty or useless
|
|
|
c79076 |
stuff for units which do not exist, and printing empty values for properties
|
|
|
c79076 |
which do not exists.
|
|
|
c79076 |
|
|
|
c79076 |
With SYSTEMD_LOG_LEVEL=debug, hints are printed, but the return value is
|
|
|
c79076 |
still 0.
|
|
|
c79076 |
|
|
|
c79076 |
This undoes parts of e33a06a and 3dced37b7 and fixes #3856.
|
|
|
c79076 |
|
|
|
c79076 |
We might consider adding an explicit switch to fail on missing units/properties
|
|
|
c79076 |
(e.g. --ensure-exists or similar), and make -P foobar equivalent to
|
|
|
c79076 |
--ensure-exists --property=foobar.
