Hi Guillaume, Your “I've recently added a bunch of important features related to spring in blueprint” sounds promising. Are there some documentation of those new features?
Regards, JP De : Guillaume Nodet [mailto:gno...@apache.org] Envoyé : mardi 12 juillet 2016 17:58 À : user@aries.apache.org Objet : Re: blueprint:cm multiple bundle but same config file I can happily review a patch if you're fancy writing one... And I disagree with the 'blueprint is dead and nobody cares about it anymore'. What's dead is the blueprint osgi specification for blueprint, not the Aries Blueprint project. I've recently added a bunch of important features related to spring in blueprint. DS also has some drawbacks as it's not extensible at all : this is leading the OSGi Alliance to write a new spec for transaction support !!! I think the CDI+DS extension I've been working on those past weeks could bring the best of both world : strong DS semantics for the OSGi bits, but extensibility and support for proxies provided by CDI ;-) 2016-07-12 17:24 GMT+02:00 Brad Johnson <brad.john...@mediadriver.com<mailto:brad.john...@mediadriver.com>>: David, I'm all for multilocation support in blueprint. Can't wait for it. But it sounds like your saying blueprint is dead and nobody cares about it anymore so it doesn't seem likely to happen anytime soon. It certainly wouldn't be relevant to Fuse which uses R4 in any case.

That's off the top of my head so take it with a grain of salt for syntax. When you run the features install it will overwrite the files in the etc directory with the ones in the maven bundle which have now been updated. So instead of modifying configuration files in the etc directory you modifying them in your Maven configuration project and recompile the bundle and then pull it from the repo in order to update the values. But you can still modify them in the etc if you wanted. You just have to make sure you have the cm properties set to reload. <cm:property-placeholder persistent-id="com.foo" update-strategy="reload"> On Tue, Jul 12, 2016 at 9:45 AM, Pablo Gómez Pérez <pablo.go...@faw.jku.at<mailto:pablo.go...@faw.jku.at>> wrote: Brad, if I understand your approach too that would lead to not being able to dynamically change common properties in a single config place during runtime, as the fill made by maven would be only done once at build time right? But at runtime I would need to that as David mention, still n times right? as a use case for instance, with blueprint:cm update-strategy configured as 'reload' in combination with felix-fileinstall as directory watcher, bundles are reloaded automatically so that when I modify at anytime during runtime a property e.g with just a text editor the bundle is initiated again with the new property values which is a quite nice feature best Pablo On 12/07/2016 12:31 AM, David Jencks wrote: I’d like to make sure I understand what you are doing here…. IIUC during the build of your project you are generating multiple configuration files with the same or similar content, and each of these is loaded into a configuration which is bound to a particular bundle location? So, at build time you can change all the duplicate properties at once but if you need to change them later you have to alter n (== number of duplicate configs) independently? Whereas if you had multi-location support (and possibly multi-pid support such as DS provides) you could share a single Configuration and change the property while the framework was running in one place? thanks david jencks On Jul 11, 2016, at 1:42 PM, Brad Johnson <brad.john...@mediadriver.com<mailto:brad.john...@mediadriver.com>> wrote: Pablo, One possible solution to this problem that I'm currently looking at is using a configuration bundle along with my features bundle. In the configuration bundle I have all the cfg files and use properties placeholders ${value} to set the value for key/value. In the POM I load properties files using the Maven properties plugin and that lets me set a global set of properties values that can be used in filling in the cfg values. So if a port or URI is shared across a large number of them that automatically gets filled in. The features file can then specify the cfg files to install and what name to install them with. This gets rid of a lot of tedium and by using profiles I should be able to switch dev, test and production, and have the properties automatically set correctly. I'd like to modify this a bit so that dev, test and product cfg files are all created simultaneously and simply installed in different directories inside the configuration bundle. Then by using different features installs I can easily switch between the different configurations without having to tediously edit each configuration file.

How does one use blueprint to not use OSGi appropriately? In the 5 years I've been consulting with Fuse/Karaf/OSGi and going to various clients not one of them used or uses DS. Not one. They all use bundles, services, and Camel with blueprint. The last time I worked with DS I didn't find it provided any serious advantage and added another layer that I'd have to teach my clients. Not that I wouldn't consider it or use it if I found a real advantage but I haven't. Red Hat is still shipping Karaf 2.x with Fuse so it is still in OSGi 4.x land much less 5 or 6. So for Camel are you using the Java DSL?

You guys might be using blueprint every day, but there is no OSGI spec work to keep it up to date or even specify obviously necessary features such as config admin integration. If blueprint is so great why aren’t the proponents keeping the spec related to current OSGI? This is a part of my, admittedly extreme, theory that use of blueprint is related to not wanting to make the app actually use osgi appropriately. And, the project I work on every day uses DS exclusively and still finds plenty of ways to abuse osgi in all sorts of inventive ways :-) david jencks On Jul 7, 2016, at 11:11 AM, Johan Edstrom <seij...@gmail.com<mailto:seij...@gmail.com>> wrote: It is in here; https://osgi.org/javadoc/r4v42/org/osgi/service/cm/ConfigurationAdmin.html A bundle is in aries bound to the pid. So it is actually working as expected, bit of a hassle since spring-dm allowed it. And yes selling DS into “regular" organizations is about as easy as selling snow in Alaska. /je On Jul 7, 2016, at 12:00 PM, Brad Johnson <brad.john...@mediadriver.com<mailto:brad.john...@mediadriver.com>> wrote: David, You live in a very different world than I do. In all the consulting I do with Fuse/karaf blueprint is used almost exclusively. I understand DS and its uses but also its limits and overhead. It's like telling me one should only use Camel Java DSL. That may be one's perspective but that isn't everyone's. Brad On Thu, Jul 7, 2016 at 12:53 PM, David Jencks <david_jen...@yahoo.com<mailto:david_jen...@yahoo.com>> wrote: IMNSHO blueprint is only really plausible if you have a large amount of Spring based code and you need to convert it to be sort of osgi-compatible really quickly without understanding osgi or the code. Otherwise taking the time to understand DS and use it is much more satisfactory. DS provides this configuration override ability with support for multiple pids, although only one of the pids can turn out to be a factory configuration. There’s no obvious way of correlating factory configurations, so this restriction makes some sense. I don’t think there really are any blueprint folks. The cm stuff, while obviously required to make the spec remotely plausible, hasn’t made it into the spec in the many many years it’s been sitting around. david jencks On Jul 7, 2016, at 10:41 AM, Brad Johnson <brad.john...@mediadriver.com<mailto:brad.john...@mediadriver.com>> wrote: If I were to sit down with the blueprint folks today to create a wish list one thing I'd like to see is for an ability to have a configuration hierarchy specified with parent/child relationships much like one has in Maven. Have a base configuration file and be able to have another cfg file specify that one as its parent. Override properties or add them to the child. When the configuration admin fires up it would read up the chain and construct the properties. On Thu, Jul 7, 2016 at 12:37 PM, Brad Johnson <brad.john...@mediadriver.com<mailto:brad.john...@mediadriver.com>> wrote: Ray, If I understand your question right the answer is the Aries extension is referencing configuration. In karaf/fuse for example the following: <cm:property-placeholder persistent-id="com.my.foo" update-strategy="reload"> will load properties from etc/com.my.foo.cfg Installing that file is done either manually or by use of a features file. Whenever I've attempted to use the PID in more than one bundle it has failed and I don't think it is permitted. That's a problem I think and something that should be fixed through some other configuration management mechanism. Making microservices that might share common properties, for example, becomes problematic in that regard and I've resorted to using my own OSGi services to overcome that problem.
