Update on Async event doc

by Antoine Sabot-Durand

Hi all, I compiled all the feedback and decision we took regarding async events and updated the Google Doc : https://docs.google.com/document/d/1Tm_fZWS6569YqCH9lGxuqBGzS9gfupic-vv1d... <https://docs.google.com/document/d/1Tm_fZWS6569YqCH9lGxuqBGzS9gfupic-vv1d...> The following point stays open. I’d like to close them (if possible) during the next meeting on Tuesday 1) Async delivery mechanism (comment by Jozef) Should we write in the spec about how threads for events delivery should be used? Personally I’d rather not: I think this should be let to implementation, the specification should only describe the expected behavior (concurrency or not). now I may have missed something. 2) Exception Handling (comment by Jozef) I didn’t write anything about exception and we should decide what happens if an exception occurs in an observer during async event dispatch. I think that it shouldn’t impact other observers and that we should stick to the way CompletionStage API works today. 3) Async event activation on both ends We all agree that we need to explicitly fire event asynchronously on the producer side (fireAsync()). The discussion in 8.1 is about adding a way to accept async call on the consumer (observer) side. a) As events are often triggered in other parts of the application than the parts that consume them (most CDI framework lib fire events foe end user code) preventing user to decide if an observer can be called asynchronously could lead to issues and will prevent library developper to use fireAsync() (in a defensive coding approach). b) On the other hand, when placed in the same application, it’ll be very confusing for user to have to fireAsync() and enable async observer to activate this new feature. I propose an opt-out approach. We add ‘asyncSupported' member to ‘@Observes' annotation with ‘true’ as default value. So in case of b) the end user won’t have to explicitly activate async on observer and i case of a) user detecting issue coming from async treatment of an event can explicitly declares one or more observer not compatible with async resolution with @Observes(asyncSupported=False) 4) Support observer ordering with async events I think we should keep event ordering for synchronous event and ignore this feature in async event. I don’t see obvious use case to be async and ordered. 5) Context propagation I understand that propagating contexts in async event would impact easily context API. My only concern here is to be define async event to keep this feature possible. If I forgot points please comment this mail and the doc so we can take final decision during next meeting. Thank you Antoine

Async event material

by Antoine Sabot-Durand

Hi all, For the info there are 2 docs (https://docs.google.com/document/d/1wJFvThqS8SrmKiuWsWgWH252k58PHGvM_iKeP... <https://docs.google.com/document/d/1wJFvThqS8SrmKiuWsWgWH252k58PHGvM_iKeP...> and https://docs.google.com/document/d/1Tm_fZWS6569YqCH9lGxuqBGzS9gfupic-vv1d... <https://docs.google.com/document/d/1Tm_fZWS6569YqCH9lGxuqBGzS9gfupic-vv1d...>) and a lot meeting transcript on the subject (http://transcripts.jboss.org/meeting/irc.freenode.org/cdi-dev/2015/index.... <http://transcripts.jboss.org/meeting/irc.freenode.org/cdi-dev/2015/index....>). I know it’s not fun to read all these (some info is outdated) but it’s a nice way to understand all the point we already discussed and avoid going back on them without a good reason. Yes, we spent a looooot of time on this async stuff but remember it’s the number 1 requested feature by our end user so we should really avoid f***ing it up. Antoine

Re: [cdi-dev] Invitation: CDI weekly meeting - Toutes les semaines entre

by Werner Keil

It's all French, but I suppose the meeting is today not tomorrow? As mentioned, I can't use IRC in the office, and there's an overlap with JSR 364 (phone call works as long as it's not an international line) so I won't be able to join this week I'm afraid. If Europe also gets to Daylight Saving, the other call may be later, then I could probably attend both (from home;-) Werner On Tue, Mar 17, 2015 at 4:06 PM, <cdi-dev-request(a)lists.jboss.org> wrote: > Send cdi-dev mailing list submissions to > cdi-dev(a)lists.jboss.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.jboss.org/mailman/listinfo/cdi-dev > or, via email, send a message with subject or body 'help' to > cdi-dev-request(a)lists.jboss.org > > You can reach the person managing the list at > cdi-dev-owner(a)lists.jboss.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of cdi-dev digest..." > > > Today's Topics: > > 1.

CDI SE Google Doc Updated

by John D. Ament

HI all, Apologies for being a week late on getting this doc together. I had some personal issues pop up after my leg came out of its cast that consumed most of my week last week. Anywho, I've updated the doc with a summary of what was discussed with CDI SE bootstrap support. You can find that here: https://docs.google.com/document/d/1LgsGT-AAlrF72Z5pW4xNQiVjUHGUME46ZmB-w... There are two minor changes that I made from where we last discussed, as when I was putting together code I found some gaps and figured it best to fix them here than later. 1. CDIProvider does not implement AutoCloseable. Since CDI class maintains a reference to the provider, implementing AutoCloseable was not adding anything. 2. I added a method boolean isInitialized() so that the caller can know if they need to start the container (or if it's already running). Locally, I've also modified the CDI.current() method to use getCDIProvider() instead of internally finding the provider since we now have a getter. One thing I'd like to get feedback on is if calling initialize/shutdown in a container should throw IllegalStateException, or probably better to throw UnsupportedOperationException when called in EE containers. Let me know your thoughts. John

[JBoss JIRA] (CDI-26) Bootstrap API for CDI

by Jozef Hartinger (JIRA)

[ https://issues.jboss.org/browse/CDI-26?page=com.atlassian.jira.plugin.sys... ] Jozef Hartinger commented on CDI-26: ------------------------------------ An alternative proposal that does not prevent parallel container instances: {code:java} public abstract class ControlledCDI<T> extends CDI<T> implements AutoCloseable { public static ControlledCDI<Object> initialize() { // TODO: Use CDIProvider internally to talk to the impl } public static ControlledCDI<Object> initialize(Map<String, Object> properties) { // TODO: Use CDIProvider internally to talk to the impl } public abstract void close(); } {code} Usage: {code:java} try (ControlledCDI<Object> cdi = ControlledCDI.initialize()) { Foo foo = cdi.select(Foo.class).get(); System.out.println(foo.computeResult()); } {code} Note that this is a preliminary proposal. The class name is subject to change plus we'll most likely need a builder API instead of the static methods in the end. > Bootstrap API for CDI > --------------------- > > Key: CDI-26 > URL: https://issues.jboss.org/browse/CDI-26 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Packaging and Deployment > Affects Versions: 1.0, 1.1.PFD, 1.2.Final > Reporter: Pete Muir > Fix For: 2.0 (discussion) > > > Weld and other CDI impls allow an embedded mode. > See http://docs.jboss.org/weld/reference/latest/en-US/html/environments.html#... for example -- This message was sent by Atlassian JIRA (v6.3.11#6341)
