[ovirt-devel] removed some marked fields from instance type
Hi all, as you may know, a subpart of the instance type entity (the marked column from [1]) are the ones which are marked with the chain icon in the VM dialogs. The meaning is that this fields are so important that if you want the newly created VM to be based on that instance type, you can not change any of this fields. The problem was that too many of the fields was marked which would force the user to create lots of instance types like: big with soundcard, big with smardcard and soundcard, medium with smardcard and without soundcard etc. This after some more thinking seems to be an incorrect approach - the list of marked fields should be small and contain only the really most important fields which lets you to categorize the VMs and not all the devices. I have proposed two patches ([2], [3]) which implement this. According to this patches only the following fields will be marked: - memory size - num of sockets/cores per socket - HA - migration model/downtime - priority - balloon - min allocated memory So the behavior will now be: - the instance type still contains all kinds of devices we support - only a small part of them are marked - when the user creates a VM from an instance type, he will be provided by a big set of defaults from the instance type he can tune - he will also be provided by a small set of fields he can not change if does not want to be detached from the instance type Thoughts?

I see two approaches here. The typical one is to define APIs for modules to consume. For example, oVirt Engine extension API has API for auth stuff; oVirt UI plugin API has API for showing tabs and dialogs, etc. The advantage is strict consistency, disadvantage is burden of having to maintain the whole API. With this approach, you tell modules: This is the API to work with system, defining how you can plug into it. Now turn 180 degrees. The other approach, which is really interesting, is to let modules themselves export API. This naturally leads to module hierarchies. Ultimately, this leads to micro-kernel-style development, where all logic resides in modules. Now you might ask: What if we want to employ some consistent work flow across multiple modules? For example, have some pluggable *auth* infra? -- this can be done via some higher level module, that exports API and lower level modules consume that API. If you have any ideas, please share! Both solutions can be applied using existing extension api, an extension can locate other extension and interact with it the same way the core interacts with extensions.

In other words, extension would not need to implement core-specific API (there would be none), instead it would inject its dependencies (other modules/extensions) and

Re: [ovirt-devel] Thoughts on modularization
Hi, I can summarized that you want again to go into the Java way and not the Simple/primitive way. I think it is a mistake and will not have any benefit, API can be a wrapper over primitive interaction. We were there at past discussions, and as there is no leader of project we can discuss this to death, and I am not intend to do this yet another time (we have done this at branding, we have done this for aaa, partially for ui plugins [there we should kill gwt], and ...). I will make this short... 1. the current extension api is sufficient to construct a very complex implementation using very simple and primitive interface. 2. the current extension api enable implementing extensions using non java technologies, such as javascript/jpython. 3. the current extension api enable to not have any difference if core or extension interacts with extensions. 4. the current extension api enable forward and backward compatibility in simple methodology,. 5. a wrapper over the extension api can provide whatever high level api that is preferred by developer as an optional utility. we can always over engineer solution or have java specific solutions, I always vote for simplicity.

Both of which have polyglot bindings (GWTExported, will migrate to @JsType later). Implicitly Maven is our unit of modularity, with maven dependency tree to declare this - however this is not recognised in any internal registry. CDI just scans and picks up any @Screen, @Perspective etc. But could be added, to give physical representation of that unit of modality, with life cycle callbacks - we just haven’t had a need for this yet. For us, I'd like to have modularity implemented in a way to avoid the big GWT app compilation step. Doesn't matter if we ultimately go for pure modular approach or core that invokes modules approach, the big goal for us is to split frontend build into several projects. Maven as unit of modularity is cool but only for compile-time-known projects. I'd like to try a different approach, as you wrote - give them some physical representation and load them at runtime. Our plan over 2015 is to use JsType to create a contract for all the things a module needs. We will then compile modules separately against this, with iframe separation, so each Module is loaded as a separate GWT app. This does mean GWT core repetition, a pita, but that atleast gets us started and may be solvable by a custom GWT linker. Actually, this iframe approach is what we took in oVirt UI plugins! :) So I see that you're approaching modules from GWT perspective, sounds interesting. However, there are already existing JS frameworks and tools that solve modularization (but they come from JS perspective), like RequireJS (AMD) or ES6's module spec. Assuming JS is here to stay as the dominant web UI technology, I'd rather utilize existing ES6 modules than implementing some GWT-specific module system on my own. But let's discuss that in detail next week. Longer term we’d like to work with GWT team. They now use the Closure compiler, this support symbol tables, and I expect how their incremental compiler works for their super dev mode. We want to achieve two things 1) stop recompilation of maven modules, when aggregated into sub projects. 2) declare apis that cannot be pruned 3) export a symbol table to allow later compilation of runtime extensions against those, without requiring a repetition of the GWT core (i.e. problem with our first attempt). Very interesting stuff! :) We will still continue with our polyglot bindings approach, such as with the AngularJS stuff we have done. But I do not see this as the ideal programming model - it hides much of what Errai brings, around event bus, and general java refactoring capabilities. However it is still useful for our customers, who want to write extensions, but do not want to touch or learn GWT. If we take modular approach, nothing prevents us to implement root module in UberFire/Errai and expose high-level API for sub-modules to consume. Sure, GWT/Java brings advantages of Java statically typed language and its development/build tools, I agree. The concept of event bus is also good as it allows decoupling of application components. For me, learning lessons from oVirt UI plugins, I'd rather avoid the have core app as runtime monolith and just expose some JS API for small extensions customers can do scenario. I'd rather treat both core and 3rd party modules/extensions on the same level.

[ovirt-devel] GWT-Platform MVP tech session - anyone interested?
Hi guys, few days ago, I gave my ancient (Dec 2011!) GWT-Platform [1] Model-View-Presenter tech session to a couple of colleagues so that they better understand our frontend infra/structure. [1] https://github.com/ArcBees/GWTP This session was meant to explain the core concepts of GWTP framework. Would anyone from community be interested in this session? Regards, Vojtech ___ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel
