Catch a lot of old URL's and update them. Also remove a couple of old files that aren't used.
Changed the server to use the external util package. Quite a minor change, but does affect a lot of files.
Added URL to GPL headers.
i-scream is now licensed under the GPL. I've added the GPL headers to every source file, and put a full copy of the license in the appropriate places. I think I've covered everything. This is going to be a mad commit ;)
Split the CORBA side of the filter in two. The Filter interface still does the receiving of data, just like it used to. This can optionally be turned off in the configuration if required. The new interface, FilterInfo, is used to provide information (host and ports) to other parts of the server about the Filter - namely the FilterManager. This split has been done so that the data receiving part of the Filter can be turned off, without breaking the FilterManager.
Major change in the java package naming. This has been held off for some time now, but it really needed doing. The future packaging of all i-scream products will be; uk.org.iscream.<product>.<subpart>.* In the case of the central monitoring system server this will be; uk.org.iscream.cms.server.* The whole server has been changed to follow this structure, and tested to a smallish extent. Further changes in other parts of the CMS will follow.
Fixed a long standing problem with the Filter not returning it's own host address (fqdn) on windows machines. It's a bit of a workaround, but at least it works :)
The whole server package structure has been changed. Old Package: uk.ac.ukc.iscream.* New Package: uk.org.iscream.*
General tidy up, specifically focussing on the verbosity of logging messages.
Fixed a blatantly wrong comment !
Changes to reflect move of Component, ComponentStartException, and the ReferenceManager from util to componentmanager.
A structural change to the Filter. The old setup looked like this; UDPReader ------> FilterThread (thread) --> (parent) TCPReader ------> FilterThread (thread) --> (parent) FilterServant --> FilterThread (thread) --> (parent) Seeing this from a threaded point of view, each time a packet came in (through whatever means - UDP, TCP or CORBA), a FilterThread instance was created to deal with it. If the link to the parent was slow this resulting in a build-up of FilterThreads all waiting to talk to the parent - and there is only one actual parent object, with a synchronised thread, so they have to queue up anyway. As a result of this, the following change has been made. UDPReader -------\ TCPReader ----------> Queue (single) >-- FilterThread --> (parent) FilterServant ---/ In this setup, each of the three objects that generate packets only see the single instance of a Queue. They all add their data to this Queue, and then carry on with the task of listening. The FilterThread (having it's role changed slightly) now acts as a consumer of the Queue, in that it grabs data from the Queue and deals with passing it on to the parent. This setup should be more efficient in the long run, especially under a high load situation. The only problem could be the Queue growing to an unlimited size, but this is a Queue design issue.
componenterized the filter and tidied all child classes, no all conform to toString standard
Changed package structure uk.ac.ukc.iscream.refman and xml -> uk.ac.ukc.iscream.util
Changed all classes so that references to the Logger and ConfigurationManager are no longer passed around between classes. All of the classes now utilise the new ReferenceManager, which makes life much easier. Also tidied everything so that they all use the same conventions for attributes, namely the _ prefix to the name.
Update for package move. Fixed bug in constructors.
Made changes to fit into the new package structure. Also made all classes, namely the UDPReader and FilterThread, conform to the Template class specification.
We don't really need this test line.
Changes to reflect the alterations Paul made in the FilterThread.
This needed to be able to provide port details, and the hostname.
Added passing of parent filter reference.
Added comments as a reminder to what will be done.
Servant for the Filter. Listens for incoming connections over CORBA.
