6a5ca2ab36 make the procedure for killing child processes of services configurable 2017-09-14 16:17:20 -05:00
William Hubbs
2b0345165e 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.

17b5cc78d3 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.

4c89e3f5fa supervise-daemon:create multiple options from --respawn-limit
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.

3673040722 supervise-daemon: add a --respawn-limit option
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.

50fccf47d4 sh/gendepends.sh.in: fix detection of service scripts
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.

sh/openrc-run.sh: expose default start/stop/status
Supervisor setups break easily when start/stop/status functions are not
default.

Applications that write multiple PIDs to a pidfile (eg HAProxy as
described in bug 601540), can also benefit from being able to call the
default start/stop/status with modified environment variables.

Expose the default start/stop/status functions as
default_start/stop/status, and use them for the defaults
start/stop/status.

Trivial usage example:
```
  stop()
  {
    t=$(mktemp)
    for pid in $(cat $pidfile) ; do
      echo $pid >$t
      pidfile=$t default_stop
    done
    rm -f $t
  }
```

bbf98befb8 sh/init.sh.Linux.in: update test for live /proc to use md5sum
This allows us to avoid the warnings from bash-4.4 about null bytes in
command substitutions.

If you have separate /usr, are not using an initramfs, and have a file
called /proc/self/environ on your root file system, this will break.

beaa71df0a binfmt.sh: use read in raw mode
The read builtin in most shells will interpret backslash characters
as escapes, and they are lost when reading binfmt files line-by-line.
This causes magic strings containing backslashes to be mangled and
become invalid, resulting in erroneous 'invalid entry' messages.

The -r option to read disables special handling of backslashes and
keeps all lines intact.

000503fad7 Convert OpenRC to a centralized copyright/license structure
In the past, OpenRC was a hybrid of a centralized and file-scope
license/copyright structure.

I followed the instructions from the Software Freedom Law Center [1] to
convert to a Centralized structure where possible, for easier future
maintenance.

33d3f33b3c Implement "want" dependency
The want dependency is similar to the use dependency. If a service
script, for example called service1, adds "want service2" to its depend
function, OpenRC will attempt to start service2, if it exists on the
system,  when service1 is started.

However, service1 will start regardless of the status of
service2.

a59365a582 start-stop-daemon.sh: complain in start if command is undefined
The default start-stop-daemon start function expects the command
variable to be defined to point to the daemon we want to start.

If the variable is undefined, this means that there will be nothing to
start, and in this case we should complain because it is possible that
the script writer made a typo in the variable name.

6a42298257 tmpfiles: run restorecon on the entire path
The tmpfiles "d" entry will create a full path and only the last dir in
the path will have its SELinux label set correctly. This patch will
restorecon the parents as well so that the selinux labels are correct.

eg, "d /run/libvirt/lxc", then "lxc" would have the correct SELinux
label but "libvirt" would not.
