[ http://issues.apache.org/jira/browse/HARMONY-27?page=all ]
Paulex Yang updated HARMONY-27:
-------------------------------
Attachment: OSNetworkSystem.h
OSNetworkSystem.c
OSNetworkSystemWin32.c
Following the JNI interfaces I attached before, here goes the native
implementations. The OSNetworkSystem.h is the JNI header file generated by
javah, and OSNetworkSystem.c is portable implementation, OSNetworkSystemWin32.c
is the complement of OSNetworkSystem.c, which are win32 platform dependent.
Most (I guess 90%) of these methods are refactored from the original socket
native codes located in luni component, including simpl.c, psimpl2.c,
pssimpl.c, pmsimpl.c and pdsimpl.c (and for sure, these files can be replaced
if relevant Java files are done), the modification to these methods only
limited to change name to Java_java_net_***Socket_*** to
Java_com_ibm_platform_OSNetworkSytem_***, etc. Others are added to meet
channels' needs.
Those methods in OSNetworkSystem.c depend heavily on the port library, so that
they should be compiled on different platform easiy without change, I've tested
on RedHat 9 and Win32. Further more, the two methods in OSNetworkSystemWin32.c
are platform specific just because there are some pitfalls in port library:),
hope we can get around it later.
There are still some TODOs left to use these files
1. Java codes
2. Some minor changes to other native files, i.e., the method declarations
within original sockect.c should be moved to socket.h
3. The JCL_CACHE_GET/SET macros using is not refactor yet, and temporarily I
work around it by using reflection directly, and the nethelp.c needs some
straightforward modification to add these reflection helper methods. I will
attach a patch later to refactor the caching mechanism and avoid performance
regression.
