ASF subversion and git services commented on VCL-966:
-----------------------------------------------------
Commit 1793863 from [email protected] in branch 'vcl/trunk'
[ https://svn.apache.org/r1793863 ]
VCL-966
Reworked Upstart.pm to be able to control some service control functions for
services that can't be controlled by initctl.
Added Upstart.pm::_get_service_info. Much of it was previously in
get_service_names. Added call to 'service --status-all' after 'initctl list' is
executed. The service command may show additional services which can't be
controlled by initctl such as xrdp. A hash is constructed containing service
name keys and the utility used to control the service (service/initctl) as the
values.
Added subroutines:
* Upstart.pm::_controlled_by_service_command
* Upstart.pm::_call_service_start
* Upstart.pm::_call_service_stop
* Upstart.pm::_call_service_restart
* Upstart.pm::_call_service_status
Added code to start_service, stop..., etc to check if the initctl or service
command should be used via _controlled_by_service_command. If service is used,
the corresponding _call_service_* subroutine is called.
Included code in _call_service_stop to overcome problems due to bugs in the
xrdp service. It doesn't always clean up the .pid file and this prevents the
service from being restarted.
> Ubuntu not detecting SysV-controlled services if chkconfig is not installed
> ---------------------------------------------------------------------------

> Key: VCL-966
> URL: https://issues.apache.org/jira/browse/VCL-966
> Project: VCL
> Issue Type: Improvement
> Components: vcld (backend)
> Affects Versions: 2.4.2
> Reporter: Andy Kurth
> Fix For: 2.5
>
>
> SysV-controlled services are not being correctly detected in Ubuntu if the
> _chkconfig_ utility is not installed. An example is xRDP. When installed
> via apt-get, the xRDP service is controlled by SysV. The service appears if
> you run *service --status-all*:
> {noformat} [ + ] xrdp{noformat}
> The code is attempting to call *chkconfig*. On Ubuntu 14 and possibly
> others, this utility is not available on recent versions of Ubuntu.
> As a result, warnings are generated in vcld.log:
> {noformat}
> Linux.pm:command_exists|5567|'chkconfig' command does NOT exist on vm1,
> command: which chkconfig
> Linux.pm:service_exists|3438|'xrdp' service is not controlled by Upstart init
> module (0)
> Linux.pm:service_exists|3443|'xrdp' service does not exist on vm1
> {noformat}
