Hi Michael
I know/see a lot of activity here, so I assume you are always quite busy and may have missed my last reaction?
Yes, sorry, I missed this, or didn’t know what to say. Feel free to remind me if you didn’t hear from me within a couple of days.
Should I proceed with my proposition to add Summary: SUMMARY Services: SERVICES to the pak metadata including an INSTALL_SERVICE_INITSCRIPTS macro
I would say yes. Do we have any unanswered questions left?
Not for this patch-set at the moment, I think..
Is Jonatan happy?
I don't know.. @Jonatan, are you happy? :-)
Should I also add InitScripts: INITSCRIPTS for non-service initscripts.. just for completion of metadata ?
Hmm, I would say no. If there is no point to it, then leave it.
We can always add it later if we decide that we want it later.
In the light of possibly adding this later, I opt for the more generic INSTALL_INITSCRIPTS macro accepting a list of initscripts to install. Most common way of calling it from the lfs files would then be:
$(call INSTALL_INITSCRIPTS,$(SERVICES))
And in that case a more generic INSTALL_INITSCRIPTS macro accepting a list of initscripts to install? (see mail history below for explanation of my intentions)
Or should we find other methods to have this info ready for services.cgi and/or monitoring agents ?
No, I believe this is a good solution. We can then have a function that queries the package database and shows all services correctly.
That sounds clean to me and is re-usable and extensible.
I think so too.
I started working on changing all pak-lfs files with the additional fields. When finished and tested, how should I post this change ? As there are about 200+ lfs files that wil be modified, mostly just adding a SUMMARY and SERVICES field. Should I post those changes as one big patch? I assume no-one will be happy if I start posting 200+ patches into the mailing list?
I could try splitting up into patches containing only non-service paks, and another containing all paks installing initscripts, and then maybe some separate patches for lfs files that contain some corner cases should I encounter such paks ?
This of course next to patches to add the INSTALL_INITSCRIPTS macro and pakfire library change to read/use this additional metadata.

Hello Jonatan,
Yes I get your point. Just because a package has more than one initscript does not mean they both should be listed in services.cgi.
It is a weird corner case, but how do we want to handle this?
-Michael
Maybe a slight renaming of my proposed new variable INITSCRIPTS to SERVICES in the LFS files would make it a bit more clear that this concerns only service-initscripts?
The INSTALL_INITSCRIPTS macro could then be renamed to INSTALL_SERVICE_INITSCRIPTS.
If we then also keep the original INSTALL_INITSCRIPT macro, that macro can then be used to install non-service initscripts if required. Or even to install all required initscripts in the occasion that you want to skip some service-initscripts defined in SERVICES because they are included in the source, like the situation Jonatan pointed out (in this case the SERVICES variable is filled with the sole purpose to serve as metadata).
So this would then result in:
define INSTALL_INITSCRIPT install -m 754 -v $(DIR_SRC)/src/initscripts/packages/$(1) /etc/rc.d/init.d/$(1) endef
define INSTALL_SERVICE_INITSCRIPTS for service in $(SERVICES); do \ $(call INSTALL_INITSCRIPT,$$service) || exit 1; \ done endef
Optionally we could also add again a variable INITSCRIPTS with the purpose to list non-service initscripts. so SERVICES - for service-initscripts INITSCRIPTS - for non-service-initscripts
and in the meta-* files:
Name: NAME Summary: SUMMARY ProgVersion: VER Release: RELEASE Size: SIZE Dependencies: DEPS File: NAME-VER-RELEASE.ipfire Services: SERVICES InitScripts: INITSCRIPTS
Maybe that info could also come in handy sooner or later ?
This sounds rather complicated to me.
What are our objectives here? Does Zabbix want/need to start/stop services? And if so, why?
I was not directly thinking of Zabbix specifically here. The objective is to have a central 'database' of metadata for the pak's that can come in handy for current and possibly future functionality of IPFire. And a single way of retrieving this information (both by using "pakfire info" or directly accessing the pakfire library, in my proposal).
Knowing which pak's provide which services can be used in service.cgi (which currently does give users the possibility to start/stop services indeed) and can be used for monitoring agents like Zabbix, but also Nagios or possibly others to know which services to monitor.
This instead of my earlier proposal of re-using parts of the services.cgi code in a separate script for zabbix_agentd, which you pointed out that should be done cleaner using some central way of storing/retrieving that information.
Zabbix does have functionality to implement starting/stopping those services using a context menu in the Zabbix web GUI; and a user can easily implement that on it's own (as this should be done mainly on server-side anyway) if he wants to and has the information of which services should run. This could be done by zabbix server logging into the IPFire machine using ssh and using addonctrl or by the agent, which would then need permission to addonctrl start/stop. But I think that is something for the user to decide on his own as you pointed out previously, giving zabbix agent root permission on addonctrl start/stop is a possible extra security risk. So I don't think we should provide that out of the box. (Maybe it could be a configurable 'setting' in the IPFire webgui some time in the future, but not something to focus on currently)
But with that said, I don't really understand your remark here as I only propose a way for the LFS files to populate the "Services" meta- data and I only threw in "Initscripts" for non-service initscripts, just for completeness of the meta-data. And to prevent duplication of the list of initscripts, I added a macro to install those in one go instead of again 'defining' this list by needing to call INSTALL_INITSCRIPT individually for each initscript while we now have a list of them in a variable. And due to the remark of Jonatan I now also kept the original INSTALL_INITSCRIPT for the pak maintainer to use in corner cases.
But this has nothing to do with actually stopping/starting services other that providing information about which services are installed (and maybe could be stopped/started if wanted).
If it would make things more clear, I could work my last mail out in an actual patch ?
Regards Robin
In this case the INSTALL_SERVICE_INITSCRIPTS could again be renamed back to INSTALL_INITSCRIPTS, now accepting a parameter which is a list of initscripts to install, so one could call:
$(call INSTALL_INITSCRIPTS,$(SERVICES)) $(call INSTALL_INITSCRIPTS,$(INITSCRIPTS))
to install all initscripts.
Or even provide again an additional macro INSTALL_ALL_INITSCRIPTS which would then install both SERVICES and INITSCRIPTS (or even replace the above suggested INSTALL_SERVICE_INITSCRIPTS, so resulting in a macro to install all initscripts (SERVICES and INITSCRIPTS) and a macro to install a single initscript in case some of the ones listed in SERVICES and/or INITSCRIPTS need to be skipped..
But I think the INSTALL_INITSCRIPTS which takes a list of services to install as parameter is probably the most generic one, giving you the possibility to install all SERVICES in one go, and then individually install only those INITSCRIPTS not included in the source if INITSCRIPTS contains such initscript(s) or vice versa.
