[JBoss JIRA] Created: (JBREM-1026) Add service metadata
by David Lloyd (JIRA)
Add service metadata
--------------------
Key: JBREM-1026
URL: https://jira.jboss.org/jira/browse/JBREM-1026
Project: JBoss Remoting
Issue Type: Task
Security Level: Public (Everyone can see)
Components: r3 api
Reporter: David Lloyd
Fix For: 3.0.0-M3
A RequestHandlerSource (aka a forwarded service) needs methods to query static metadata, such as:
1) The presence or absence of ordering guarantees across the total path
2) Security information about the total path (encryption strength for example)
3) Path information (like a traceroute, for cost as well as diagnostic information; could include link cost, transport type & version, etc)
4) Possibly authentication information about the total path
It should be possible to add new metadata types later on without interfering with backwards compatibility. So lack of a given metadata type must be considered to be possibly indicative of an older version along the path.

[JBoss JIRA] Created: (JBREM-1009) Streaming should work with packet-based channels as well as stream-based channels

Streaming should work with packet-based channels as well as stream-based channels
---------------------------------------------------------------------------------
Key: JBREM-1009
URL: http://jira.jboss.com/jira/browse/JBREM-1009
Project: JBoss Remoting
Issue Type: Task
Security Level: Public (Everyone can see)
Components: r3 api
Reporter: David Lloyd
Assigned To: David Lloyd
Fix For: 3.0.0-M3
OutputStreams and Writers are trivially implemented using streams - writes to the remote object are simply propagated across to channel. Other types of streams are more difficult to implement this way. InputStream for example has two types of messages - a data chunk and an exception chunk. Because of this, some basic framing is necessary; with only support for streams, this framing must take place within the stream handler which is a pain to implement.
So, a stream serializer should be able to register itself as a byte stream handler (using a StreamChannel) or a message stream handler (using a MessageChannel).
