[Dazuko-devel] Dazuko 2.0.0 Released (and birthday!)

[John Ogness]

Hi,

Today (Feb 5) is Dazuko's birthday! 2 years old! For this special 
occasion I am very happy to announce the official release of Dazuko 
version 2.0.0. This version is truly a landmark in the history of 
Dazuko. The introduction of the abstraction layer, the new key/value 
device protocol, and the use of write() instead of ioctl() are major 
changes that will enable Dazuko to quickly advance to new platforms and 
allow for problem-free future expansion.

This new version also introduces a "call_" layer. For example, rather 
than xp_malloc() being directly called, the XP layer now calls 
call_xp_malloc(). This extra "call_" layer checks the arguments before 
calling the real function and checks the return values before they are 
returned. If problems exist (for example, kmalloc() returns NULL), then 
this information is output as warning messages. Although these 
situations are properly handled in the XP layer, this extra check 
provides additional information for a "just in case" scenario. Since 
these functions are inlined by the compiler, they have a minimal affect 
on performance.

I have also changed the package structure a bit. The Java interface has 
been integrated into the main package and the example programs have been 
moved into example_c and example_java sub-directories. Each of these 
directories has their own Makefile.

I have labeled 2.0.0 as stable. I am very comfortable with this version 
and recommend that all Dazuko 1.x developers make the switch. This 
version provides more features, more information with more events, has 
more safety checks, and runs on more platforms.

Dazuko's TODO list seems to be growing faster than it is shrinking. Some 
very important items have come up recently and I will need to prioritize 
(and make public) a plan of how we should proceed. Now that 2.0.0 is 
out, focus can be moved away from debugging/testing and moved back into 
new features.

This last year has been very exciting. I can hardly wait to see what 
this year brings. :)
