[JBoss JIRA] Created: (JGRP-931) Logical addresses: canonicalize UUIDs with IDs (shorts)

by Bela Ban (JIRA)

Logical addresses: canonicalize UUIDs with IDs (shorts) ------------------------------------------------------- Key: JGRP-931 URL: https://jira.jboss.org/jira/browse/JGRP-931 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.9 Instead of using UUIDs as addresses, the cluster members should agree on shorts, e.g. 1 for A, 2 for B and so on, and use these instead of UUIDs. This happens after a certain warmup time. E.g. the coord could assign these IDs, so they're unique. IdAddress and UUID have to be able to do equals() or compareTo() with each other ! Advantage: - we send a short (2 bytes) instead of a UUID (16 bytes) - we use an IdAddress (class with a short) instead of a UUID. This is 6 bytes less per instance - IdAddress might be faster with equals() and hashCode() than UUID -- 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-670) Migrate existing Nexus Audit information to standard XML format

by Paul Gier (JIRA)

Migrate existing Nexus Audit information to standard XML format --------------------------------------------------------------- Key: JBBUILD-670 URL: https://issues.jboss.org/browse/JBBUILD-670 Project: JBoss Build System Issue Type: Task Reporter: Paul Gier Assignee: John Casey Fix For: Build Support 2011 We currently have audit information (username, timestamp) stored in .json files in the repository. Nexus uses an XML format to store this information, and recent versions of Nexus allow easy way to view this information in the Nexus UI. The existing audit information should be migrated to the standard Nexus XML format. These XML files are located in the directory "sonatype-work/nexus/proxy/attributes". For each file in each Maven repository hosted by Nexus, there is a file with the same name in this attributes directory. For example, "sonatype-work/nexus/proxy/attributes/jboss-releases/org/jboss/javaee/jboss-servlet-api/2.5.0.GA/jboss-servlet-api-2.5.0.GA.jar" is actually an XML file containing the attributes for the named jar file. -- This message is automatically generated by 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-1302) RELAY: issues with shared transport

by Bela Ban (JIRA)

RELAY: issues with shared transport ----------------------------------- Key: JGRP-1302 URL: https://issues.jboss.org/browse/JGRP-1302 Project: JGroups Issue Type: Task Affects Versions: 2.12 Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.12.1 JBoss 6 creates a separate channel for each of its webapps that are marked as <distributable/> when mode=distribution. The reason is outlined in https://issues.jboss.org/browse/ISPN-658. This is a problem if we have for example a stack called "relay" (and in infinispan-configs.xml the "web" configuration refers to "relay"), and the transport is shared (singleton_name is set): - webapp web.war is deployed - A channel for web.war is created by Infinispan - The channel creates the shared transport and RELAY establishes the TCP bridge cluster as first member - Webapp SessionDemo.war is deployed - A new channel is created. The shared transport is not initialized again, as it already was for web.war - However, RELAY joins the TCP bridge cluster and thus is in the same cluster as web.war ! ==> However, both subclusters are named the same ! This leads to issues -- This message is automatically generated by JIRA. 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: (JBRULES-2700) Allow setting globals for access by the scoring rules

by Wouter Horré (JIRA)

Allow setting globals for access by the scoring rules ----------------------------------------------------- Key: JBRULES-2700 URL: https://jira.jboss.org/browse/JBRULES-2700 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-planner Reporter: Wouter Horré Assignee: Mark Proctor Currently, it is not possible to set a global variable in the working memory used by the solver. If a scoring rule needs an external helper for calculating scores (e.g. a dependency injected with OSGi DS), a workaround using a static variable in some class accessible by the scoring rules is needed. The easiest implementation is probably a new method in the Solver interface: public WorkingMemory getWorkingMemory(); which provides access to the working memory used by the solver. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
