This is pre-release announcement for the Jabber Component Runtime (JCR). The JCR is designed to allow components written in "C" for the jabberd 1.4.x codebase to be run as standalone processes. What this means is that you compile the library, and then compile your component against this library (and the included 'main.c') to produce a standalone component.
Most of the commonly used jabberd 1.4.x functions (in the initial release) are included with some notable exceptions:
--- mtq_* functions:
These functions allow the developer to queue up data for a
function using 'pth' queues. While this is a nice feature, it
is not necessary (for the most part) to handle the packet
volume. --- mio_* functions:
Currently, the mio_* functions are not ported (or wrapped) for
inclusion in the library. I have found that using the 'glib'
I/O channels provide the same functionality. For porting
purposes, the code will have to be altered slightly to use
'g_io' rather than mio.The porting effort will depend how many of the above functions are used. To maintain compatibility with compiling using the jabberd 1.4.x codebase, a define is set at compile time to allow the developer to know whether the component is being compiled normally, or with the jcr. The define, '_JCOMP' is set in the Makefile provided (jcomp.mk) as an example.
The only dependency for the JCR is glib-2.0. This library provides the asynchronous I/O as well as the event loop used in the main() function.
More information will be coming in the next few days, as well as a preliminary release. The JCR has been compiled and used to build a standalone MU-C component with great success. This implementation is currently under test, and the configurations, etc. will be included in the release as the primary example.
You can read the full README and INSTALL files at http://jabber.terrapin.com/JCR. I am looking for more feedback to determine interest and what other functions need to be included. In addition, this library and runtime should make the transition to jabberd 2 much easier.
Any and all feedback is welcome, as well as questions ....
Paul
