prior to cgroups getting mounted, /sys/fs/cgroup will still exist,
but attempts to make directories in it will fail, change cgroup2_set_limits() to
verify that cgroups are mounted instead of just checking that /sys/fs/cgroup
exists.
This fixes#307.
This fixes#321.
We have used /run for some time now and we have had this migration
script for 6 years. Linux users should have upgraded by now to a version
of OpenRC which stores its information in /run.
I do not know of a need to have the default shell be a build-time
configurable setting. All *nix systems I am aware of have /bin/sh as a
default posix compatible shell.
If some systems running OpenRC do not make that assumption about
/bin/sh, I will consider bringing this back, so feel free to open an
issue.
Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.
The pidfile of the supervisor doesn't need to be adjustable by the
service script. It is only used so the supervisor can stop itself when
the --stop option is used.
Health checks are a way to monitor a service and make sure it stays
healthy.
If a service is not healthy, it will be automatically restarted after
running the unhealthy() function to clean up.
The current check only tries to detect whether /sys/fs/cgroup exists and
whether it is writable or not. But when the init system doesn't mount
cgroups then /sys/fs/cgroup will just be an empty directory. When paired
with unprivileged containers that mount sysfs this will cause misleading
errors to be printed since /sys/fs/cgroup will be owned by user
nobody:nogroup in this case. Independent of this specific problem this
check will also be misleading when the /sys/fs/cgroup exists and is in
fact writable by the init system but isn't actually a mountpoint.
Note from William. "grep -qs" doesn't need to redirect output to
/dev/null since it is completely silent.
This fixes#209.
Add the following variables to expose more arguments that can be passed
to start-stop-daemon or supervise-daemon:
- directory will be passed to --chdir
- error_log will be passed to --stderr
- output_log will be passed to --stdout
- umask will be passed to umask
This is for #184.
Add the ability to force-kill a service if it does not go down
successfully. Also, adjust the default wait time for an s6 service to go
down to 60 seconds.
This is to be used if the service is being supervised and the
supervisor is somehow killed.
Currently, this is very linux specific, but I will expand to other
platforms, patches are welcome.
Instead of looping and sending multiple signals to child processes in
cgroup_cleanup, we send sigterm followed by sleeping one second then
sigkill.
This brings us more in line with systemd's "control group" killmode
setting.
Also, this commit includes several shellcheck cleanups.
The --retry option for supervise-daemon defines how the supervisor will
attempt to stop the child process it is monitoring. It is defined when
the supervisor is started since stopping the supervisor just sends a
signal to the active supervisor.
This fixes#160.
This creates --respawn-delay, --respawn-max and --respawn-period. It was
suggested that it would be easier to follow if the options were
separated.
This is for #126.
Allow limiting the number of times supervise-daemon will attempt to respawn a
daemon once it has died to prevent infinite respawning. Also, set a
reasonable default limit (10 times in a 5 second period).
This is for issue #126.
We do not need to care about the path on the shebang line of a service
script as long as the shebang line ends with "openrc-run".
This fixes#119 and #120.
