| Apache Tomcat Trunk Proposals |
| ================================= |
| |
| |
| PATCHES PROPOSED FOR INCLUSION in 6.1.x: |
| [ The alpha/beta branch that will be the basis of the stable 6.2.x releases ] |
| [ No date has been set for the creation of a 6.1.x branch at this point ] |
| [ New proposals should be added at the end of the list ] |
| |
| |
| * Proposal |
| svn revision or other reference |
| +1: |
| -1: |
| |
| |
| * catalina-tribes.jar improvements |
| Messaging |
| ========= |
| Add in support for UDP messages |
| - fire and forget |
| - ack on message |
| - ack on batch of messages |
| - periodic ack, time or message count |
| - support multicast fire and forget |
| - autoswitch TCP/UDP based on size, number of recipients, or on message flag |
| - add in versioning to the message structure |
| - Add in a delay between bind failures, to give the JVM a chance to recover |
| Priority Messaging |
| - Being able to send through high priority messages through a channel |
| pause existing messages |
| |
| Failure Detection |
| ================= |
| Improvements to the current failure detector |
| - NIO based |
| - avoid multiple member failed messages, keep a lock on a recipient basis |
| - different levels of failure check (accept, send/receive ack) |
| Networking |
| ========== |
| Add in support to leverage multiple network cards in parallel (research |
| if any OS features are available to leverage this) |
| |
| Performance/Concurrency |
| ======================= |
| - Remove usage of "synchronized" (previously used for JDK 1.4 compatibility) |
| - make JDK 1.5 minimum version |
| - take advantage of java.util.concurrent |
| |
| Membership |
| ========== |
| - implement payloadChange(...) event on membership listener |
| |
| * Make OSGi Bundles of each jar |
| |
| * Include tomcat-juli and tomcat-juli-adapters as an add on package when doing a release |
| |
| Session Replication |
| =================== |
| - New feature - only replicate upon demand |
| Runtime tomcat doesn't do live session replication |
| but you can move the sessions upon demand before shutting down a tomcat instance |
| and draining sessions |
| |
