|

|
||||
Make cgroup_cleanup send only one sigterm and sigkill
|
||||
|
||||
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.

|

add retry option to supervise-daemon
|
||||
|
||||
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.

Deprecate automatic loading of modules
|
||||
|
||||
In the hwclock, procfs and sysfs service scripts, we automatically
|
||||
attempt to load the kernel modules we need before we take any action. We
|
||||
shouldn't do this, because there are systems which do not use kernel
|
||||
modules and do not have the kmod package installed.
|
||||
|
||||
With this change, we continue to load the modules ourselves, but we warn
|
||||
the admin that they need to be added to /etc/conf.d/modules or built
|
||||
into the kernel.
|
||||
|
||||
In the future, this automatic loading will be dropped.

# ulimit and CGroups

Setting `ulimit` and `nice` values per service can be done through the `rc_ulimit`
|
||||
variable.
|

Setting `ulimit` and `nice` values per service can be done through the
|
||||
`rc_ulimit` variable.
|
||||
|
||||
Under Linux, OpenRC can optionally use CGroups for process management.
|
||||
By default each service script's processes are migrated to their own CGroup.
|
||||
Under Linux, OpenRC can use cgroups for process management as well. Once
|
||||
the kernel is configured appropriately, the `rc_cgroup_mode` setting in
|
||||
/etc/rc.conf should be used to control whether cgroups version one,,
|
||||
two, or both are used. The default is to use both if they are available.
|
||||
|
||||
By changing certain settings in the service's `conf.d` file limits can be
|
||||
enforced per service. These settings are documented in detail in the
|
||||
default /etc/rc.conf under `LINUX CGROUPS RESOURCE MANAGEMENT`.
|
||||
|
||||
# Dealing with Orphaned Processes
|
||||
|
||||
It is possible to get into a state where there are orphaned processes
|
||||
running which were part of a service. For example, if you are monitoring
|
||||
a service with supervise-daemon and supervise-daemon dies for an unknown
|
||||
reason. The way to deal with this will be different for each system.
|
||||
|
||||
On Linux systems with cgroups enabled, the cgroup_cleanup command is
|
||||
added to all services. You can run it manually, when the service is
|
||||
stopped, by using:
|
||||
|
||||
```
|
||||
# rc-service someservice cgroup_cleanup
|
||||
```
|
||||
|
||||
The `rc_cgroup_cleanup` setting can be changed to yes to make this
|
||||
happen automatically when the service is stopped.
|
||||
|
||||
By changing certain values in the `conf.d` file limits can be enforced per
|
||||
service. It is easy to find orphan processes of a service that persist after
|
||||
`stop()`, but by default these will NOT be terminated.
|
||||
To change this add `rc_cgroup_cleanup="yes"` in the `conf.d` files for services
|
||||
where you desire this functionality.
