Subject: [PATCH v2 1/1] maintenance: use systemd timers on Linux
Date: Sun, 9 May 2021 23:32:17 +0200 [thread overview]
Message-ID: <20210509213217.449489-2-lenaic@lhuard.fr> (raw)
In-Reply-To: <20210509213217.449489-1-lenaic@lhuard.fr>
The existing mechanism for scheduling background maintenance is done
through cron. On Linux systems managed by systemd, systemd provides an
alternative to schedule recurring tasks: systemd timers.
The main motivations to implement systemd timers in addition to cron
are:
* cron is optional and Linux systems running systemd might not have it
installed.
* The execution of `crontab -l` can tell us if cron is installed but not
if the daemon is actually running.
* With systemd, each service is run in its own cgroup and its logs are
tagged by the service inside journald. With cron, all scheduled tasks
are running in the cron daemon cgroup and all the logs of the
user-scheduled tasks are pretended to belong to the system cron
service.
Concretely, a user that doesn’t have access to the system logs won’t
have access to the log of its own tasks scheduled by cron whereas he
will have access to the log of its own tasks scheduled by systemd
timer.
Although `cron` attempts to send email, that email may go unseen by
the user because these days, local mailboxes are not heavily used
anymore.
In order to choose which scheduler to use between `cron` and user
systemd timers, a new option
`--scheduler=auto|cron|systemd|launchctl|schtasks` has been added to
`git maintenance start`.
When `git maintenance start --scheduler=XXX` is run, it not only
registers `git maintenance run` tasks in the scheduler XXX, it also
removes the `git maintenance run` tasks from all the other schedulers to
ensure we cannot have two schedulers launching concurrent identical
tasks.
The default value is `auto` which chooses a suitable scheduler for the
system.
On Linux, if user systemd timers are available, they will be used as git
maintenance scheduler. If not, `cron` will be used if it is available.
If none is available, it will fail.
`git maintenance stop` doesn't have any `--scheduler` parameter because
this command will try to remove the `git maintenance run` tasks from all
the available schedulers.
In order to schedule git maintenance, we need two unit template files:
* ~/.config/systemd/user/git-maintenance@.service
to define the command to be started by systemd and
* ~/.config/systemd/user/git-maintenance@.timer
to define the schedule at which the command should be run.
Those units are templates that are parametrized by the frequency.
Based on those templates, 3 timers are started:
* git-maintenance@hourly.timer
* git-maintenance@daily.timer
* git-maintenance@weekly.timer
The command launched by those three timers are the same than with the
other scheduling methods:
git for-each-repo --config=maintenance.repo maintenance run
--schedule=%i
with the full path for git to ensure that the version of git launched
for the scheduled maintenance is the same as the one used to run
`maintenance start`.
The timer unit contains `Persistent=true` so that, if the computer is
powered down when a maintenance task should run, the task will be run
when the computer is back powered on.

TROUBLESHOOTING

+BACKGROUND MAINTENANCE ON LINUX SYSTEMD SYSTEMS
+-----------------------------------------------
+
+While Linux supports `cron`, depending on the distribution, `cron` may
+be an optional package not necessarily installed. On modern Linux
+distributions, systemd timers are superseding it.
+
+If user systemd timers are available, they will be used as a replacement
+of `cron`.
+
+In this case, `git maintenance start` will create user systemd timer units
+and start the timers. The current list of user-scheduled tasks can be found
+by running `systemctl --user list-timers`. The timers written by `git
+maintenance start` are similar to this:
+
+-----------------------------------------------------------------------
+$ systemctl --user list-timers
+NEXT LEFT LAST PASSED UNIT ACTIVATES
+Thu 2021-04-29 19:00:00 CEST 42min left Thu 2021-04-29 18:00:11 CEST 17min ago git-maintenance@hourly.timer git-maintenance@hourly.service

+-----------------------------------------------------------------------
+
+One timer is registered for each `--schedule=<frequency>` option.
+
+The definition of the systemd units can be inspected in the following files:
+
+-----------------------------------------------------------------------
+~/.config/systemd/user/git-maintenance@.timer
+~/.config/systemd/user/git-maintenance@.service
+~/.config/systemd/user/timers.target.wants/git-maintenance@hourly.timer
+~/.config/systemd/user/timers.target.wants/git-maintenance@daily.timer
+~/.config/systemd/user/timers.target.wants/git-maintenance@weekly.timer
+-----------------------------------------------------------------------
+
+`git maintenance start` will overwrite these files and start the timer
+again with `systemctl --user`, so any customization should be done by
+creating a drop-in file, i.e. a `.conf` suffixed file in the
+`~/.config/systemd/user/git-maintenance@.service.d` directory.
+
+`git maintenance stop` will stop the user systemd timers and delete
+the above mentioned files.
+
+For more details, see systemd.timer(5)
