jdk8backported package

by Radim Vansa

Hi, although we're on Java 8, there's still the package org.infinispan.*.jdk8backported in our codebase. Is there any plan (and possibility) to remove these and use implementation provided by runtime? Or have we tweaked them too much, so shall we rather rename them?

Status 2015-08-05

by Sebastian Laskawiec

Hey! Unfortunately I won't be able to join you during the status meeting on Monday, so here's what managed to do last week: - I mainly worked on HelthChack API: - https://issues.jboss.org/browse/ISPN-6679 - https://github.com/slaskawi/infinispan/tree/ISPN-6679/Healthcheck_api - Interfaces and JMX are done, the only missing bit is the Wildfly integrations (currently implemented as metrics) - Tomaz Cerar mentioned there is no way to use Custom Handlers for Management API (we can not implement gathering statistics with a custom URL like http://localhost:9990/health). We can use HTTP GET for obtaining resources or POST for operations and runtime resources. - I need to think it over and choose one of the solutions (using metrics seem to be the worst approach) - I talked with James about printing out last X lines of log - again it's not an easy task and James suggested that it can be using the logging subsystem. I will look into that too. - I fixed a couple of Windows errors for the product (they were ok in the upstream). - I started implementing a CI job for our Docker images and OpenShift - I also prepared a blog post about Infinispan and OpenShift (it will be released next week). - There are also some good news from my home city - we're opening Bydgoszcz JUG (I'd love to see you guys pronouncing "Bydgoszcz" :D) in September/October and I reserved 2 talks about Open Source (maintaining, contributing etc) and Infinispan+OpenShift/Kubernetes. Wish me luck! Thanks Sebastian

Sequential interceptors API

by Radim Vansa

Hi, I would like to encourage you to play with the (relatively) new API for sequential interceptors, and voice your comments - especially you corish devs, and Galder who has much experience with async invocations and that kind of stuff from JS-world. I am now trying to use the asynchronous methods only (the forkInvocationSync() is only temporary helper!); Dan has made it this way as he wanted to avoid unnecessary allocations, and I welcome this GC-awareness, but regrettably I find it rather hard to use, due to its handler-style nature. For the simplest style interceptors (do this, invoke next interceptor, and process result) it's fine, but when you want to do something like: visitFoo(cmd) { Object x = null; if (/* ... */) { x = invoke(new OtherCommand()); } invoke(new DifferentCommand(x)); Object retval = invoke(cmd); return wrap(retval); } I find myself passing handlers deep down. There is allocation cost for closures, so API that does not allocate CompletableFutures does not pay off. I don't say that I could improve it (I have directed my comments to Dan on IRC when I had something in particular), I just say that this is very important API for further Infinispan development and everyone should pay attention before it gets final. So please, play with it, and show your opinion. Radim -- Radim Vansa <rvansa(a)redhat.com> JBoss Performance Team

Hi all, I've created a wiki [1] for the "compatibility 2.0" ideas we talked about recently at the query meeting. This is mostly a dump of the minutes, so the form is not complete, but initial comments are welcome.
