It is called *open* source for a reason. Did you look at the svn history for 
the file in question? The same info is available by searching the archives of 
the dev list.

Search the archives of this list and you might find a few useful hints too.

There is no such document. The best you'll get is the change log.

 for example architecture , execution

Broadly, no fundamental difference. At the detail level, lots of changes, 
mainly bug fixes and improcements.

MapListener update

[jim ma]

Hi ,

When I update my code for embedding tomcat 5.x to embedding 6.x, a null
pointer exception blocks me .
I dug the code , I found it cause by the
org.apache.catalina.connector.MapperListener difference :

Tomcat5.x
---
/**
 * Register host.
 */
private void registerHost(ObjectName objectName)
throws Exception {
String name=objectName.getKeyProperty("host");
if( name != null ) {
String[] aliases = (String[])
mBeanServer.invoke(objectName, "findAliases", null, null);
mapper.addHost(name, aliases, objectName);
if(log.isDebugEnabled())
log.debug(sm.getString
 ("mapperListener.registerHost", name, domain));

}
}

Tomcat6.x
-
/**
 * Register host.
 */
private void registerHost(ObjectName objectName)
throws Exception {
String name=objectName.getKeyProperty("host");
if( name != null ) {
Host host = (Host) ServerFactory.getServer().findService(
domain).getContainer().findChild(name);
String[] aliases = host.findAliases();
mapper.addHost(name, aliases, objectName);
host.addContainerListener(this);
if(log.isDebugEnabled())
log.debug(sm.getString
 ("mapperListener.registerHost", name, domain));

}
}


Is this change to fix an issue ? Or Tomcat6.x totally change the host name
looking up mechanism .
Could you also point to me where can I find the Tomcat6.x document about
difference with Tomcat5.x if there is ? for example architecture , execution
etc.

Thanks in advance .
