cvs commit: jakarta-tomcat-connectors/jk/native2/include jk_handler.h jk_endpoint.h jk_map.h jk_pool.h jk_uriEnv.h jk_uriMap.h jk_worker.h jk_workerEnv.h
costin 01/12/05 12:45:13
Modified: jk/native2/include jk_endpoint.h jk_map.h jk_pool.h
jk_uriEnv.h jk_uriMap.h jk_worker.h jk_workerEnv.h
Added: jk/native2/include jk_handler.h
Log:
Changed 'unsigned' to normal 'int's - unsingneds are a bit confusing ( for a java
programmer :-), and the code already had few 'foo>0' or even 'foo=-1' with foo
unsigned. Please avoid unsigned if possible, for most of our stuff int should be
enough.
Continued the data structure consolidation. As I mentioned in a previous commit,
we lose some of the data hiding (the 'private' fields ), but we gain the ability
to extract detailed informations about what's going in and to control all
data structures using callbacks from tomcat.
Long term we need some 'introspection' capabilities, most likely a generic
getProperty/setProperty ( or getNote/setNote - 3.3 style ) plus getPropertyNames().
Now load balancing properties are visible in the main worker. Of course, most
of it is quite generic - for example 'realEndpoint' is to be used by any
worker that is using another worker to do the work. Having lb exposed will
eventually allow us to finish jni worker in multiprocess mode.
Added prototypes, get rid of most warnings.
