[JBoss JIRA] Created: (EJBTHREE-1975) Initial OSGi JPA implementation

by Thomas Diesler (JIRA)

Initial OSGi JPA implementation ------------------------------- Key: EJBTHREE-1975 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1975 Project: EJB 3.0 Issue Type: Feature Request Reporter: Thomas Diesler Part of Enterprise OSGi there is JPA specification that we would like to have support for. This issue is the entry point for the initial implementation. Apache Aries ------------------ http://wiki.apache.org/incubator/AriesProposal Apache OpenJPA - http://openjpa.apache.org/ Apache OpenJPA is a Java persistence project. It is related to Aries as a JPA persistence provider, including entity scanning and enhancement. The Aries project will make it easy for JPA persistence providers such as OpenJPA to be used in an OSGi environment and will provide container managed persistence for the Blueprint container. Eclipse Gemini -------------------- http://eclipse.org/proposals/gemini/ The subprojects will be created with the following initial IP components and donating companies: * Blueprint Service Implementation — SpringSource * Web Container Integration code — SpringSource * JPA Integration code for EclipseLink — Oracle * Implementation of JMX Mbeans and composite data types — Oracle * Derby JDBC Service Implementation — Oracle * JNDI Service Integration code — Oracle http://www.eclipse.org/eclipselink/ -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBBUILD-523) Issues with custom packaging in maven

by Paul Gier (JIRA)

Issues with custom packaging in maven ------------------------------------- Key: JBBUILD-523 URL: https://jira.jboss.org/jira/browse/JBBUILD-523 Project: JBoss Build System Issue Type: Task Components: Maven Reporter: Paul Gier Fix For: Maven Build - Maint 2009 Steve ran into some issues when using custom packaging for the jdocbook plugin. - Transitive dependency resolution does not work - Two dependencies with the same packaging but different artifact handlers cannot both be resolved, because no info about the handler is encoded into the repo - The plugin containing the custom packaging needs to programmatically register the artifact handler in addition to specifiying it in the components.xml this has to be done by: (1) retrieve the handler using @parameter expression="${component.org.apache.maven.artifact.handler.ArtifactHandler#jdocbook-style}" (2) manually register it using project.getArtifact().setArtifactHandler( artifactHandler ); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JGRP-1053) UNICAST: set retransmission timeout based on actual retransmission times

by Bela Ban (JIRA)

UNICAST: set retransmission timeout based on actual retransmission times ------------------------------------------------------------------------ Key: JGRP-1053 URL: https://jira.jboss.org/jira/browse/JGRP-1053 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.9 UNICAST needs to compute a rolling average of retransmission times, per sender (AckSenderWindow). The retransmission timeout per sender can then be set based on the actual average retransmission times. The advantage is that we throttle retransmission when we have a lot of message loss, and speed it up again when there are no message drops. The function to set the timeout should always compute the new timeot value based on (1) the old value times a decay factor and (2) a new value. The average should go up relatively quickly if the actual retransmission values go up, but come down slowly when the actual values go down. A potential function is shown below: static final double SLOW_DECAY_FACTOR=0.9, FAST_DECAY_FACTOR=0.7; static final double FAST_UP= 1 / FAST_DECAY_FACTOR, SLOW_UP= 1 / SLOW_DECAY_FACTOR; static final double SAFETY_BUFFER=0.3; static double avg=200; public static void main(String[] args) { final long[] times={200,200,400,400,500,500,500,500,500,100,100,100,100,100,100,100,100,100,100,100,100,100}; // final long[] times={200,200,200,200,200,200,200,200,200,200,200}; for(Long val: times) { double result=avg(val); System.out.println(val + ": " + result); } } private static double avg(long val) { double decay, up; if(val > avg) { decay=FAST_DECAY_FACTOR; up=FAST_UP; } else { decay=SLOW_DECAY_FACTOR; up=SLOW_UP; } double old_val=avg * decay; double result=(old_val + val * up) / 2; avg=result; return result * (1 + SAFETY_BUFFER); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JGRP-1054) NAKACK: retransmission timeouts based on actual retransmission values

by Bela Ban (JIRA)

NAKACK: retransmission timeouts based on actual retransmission values --------------------------------------------------------------------- Key: JGRP-1054 URL: https://jira.jboss.org/jira/browse/JGRP-1054 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.9 Currently, timeouts in NAKACK are static, e.g. 300,600,1200. The goal is to make the retransmission timeouts a function of the actual average retransmission times. Ideally, we maintain rolling averages of actual retransmission times per sender and adjust the retransmit timeout based on these values. This would dynamically slow down retransmission on heavy traffic/congetion/message loss etc, and speed it up when those problems disappear again -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JGRP-592) Pluggable policy for picking coordinator

by Bela Ban (JIRA)

Pluggable policy for picking coordinator ---------------------------------------- Key: JGRP-592 URL: http://jira.jboss.com/jira/browse/JGRP-592 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assigned To: Bela Ban Priority: Minor Fix For: 2.6 Make policy to pick coordinator pluggable. Pick new coordinator after existing coordinator crashes by calling this policy. Default policy is to pick the next in line. Other policies could pick the next in line from a set of pinned coordinator, so certain members can never become coordinators. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JGRP-495) Memory leak in NAKACK

by Bela Ban (JIRA)

Memory leak in NAKACK --------------------- Key: JGRP-495 URL: http://jira.jboss.com/jira/browse/JGRP-495 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assigned To: Bela Ban Priority: Blocker Fix For: 2.5 Probably due to the changes introduced in NAKACK/NakReceiverWindow (http://jira.jboss.com/jira/browse/JGRP-281). To reproduce, run perf.Test on 2 nodes with 1 million 1K messages each. JProfiler shows that we are leaking Map.Entry instances in NAKACK. They seem to accumulate in xmit_table. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
