Subject: [PATCH] core, job: fix breakage of ordering dependencies by systemctl
|
|
|
4b8c80 |
reload command
|
|
|
4b8c80 |
|
|
|
4b8c80 |
Currently, systemctl reload command breaks ordering dependencies if it's
|
|
|
4b8c80 |
executed when its target service unit is in activating state.
|
|
|
4b8c80 |
|
|
|
4b8c80 |
For example, prepare A.service, B.service and C.target as follows:
|
|
|
4b8c80 |
|
|
|
4b8c80 |
# systemctl cat A.service B.service C.target
|
|
|
4b8c80 |
# /etc/systemd/system/A.service
|

Start them.

4b8c80 |
|
|
|
4b8c80 |
# systemctl daemon-reload
|
|
|
4b8c80 |
# systemctl start C.target
|
|
|
4b8c80 |
|
|
|
4b8c80 |
Then, we have:
|
|

4b8c80 |
|
|
|
4b8c80 |
# LANG=C journalctl --no-pager -u A.service -u B.service -u C.target -b

The issue occurs not only in reload command, i.e.:
|
|
|
4b8c80 |
|
|
|
4b8c80 |
- reload
|
|
|
4b8c80 |
- try-restart
|
|
|
4b8c80 |
- reload-or-restart
|
|
|
4b8c80 |
- reload-or-try-restart commands
|
|
|
4b8c80 |
|
|
|
4b8c80 |
The cause of this issue is that job_type_collapse() doesn't take care of the
|
|
|
4b8c80 |
activating state.
