This patch fixes the following bugs of Ninf-G 2.4.0.

• Free memory will be accessed
• Ninf-G client aborts in grpc_function_handle_destruct() if there is an outstanding grpc_call() to the same function handle.
• A compile error occurs in AIX
• Java Client leaks memory and sockets

In addition, this patch adds Java API manual.
Instructions for applying patch are as follows (instructions are included in the patch file itself).

    % cd ng-2.4.0
    % patch -p1 < ng-2.4.0-2.4.1.diff
    % make distclean
    % ./configure
    % make

Ninf-G version 2 (Ninf-G2) is the supporting software for the development and execution of programs with the Grid Remote Procedure Call (GridRPC). Ninf-G2 is a full implementation of the GridRPC API, a proposed GGF standard. In addition to the GridRPC API, Ninf-G2 provides Ninf-G API for supporting 1) high performance on a large-scale computational Grid, 2) rich functionalities which are required to compensate for the heterogeneity and unreliability of a Grid environment, and 3) easy development and execution of Grid applications.

Details are described in Overview section in the Ninf-G version 2 users' manual. Installation instruction is described in the Installation section in the manual.
Ninf-G Version 2.4.0 is the latest version of Ninf-G2 and it is expected to be the final release of Ninf-G2. This release includes the following new features and bug fixes:

• New features
  
  • Thread-ID is put into log, when loglevel is set to 5(Debug).
  • Ninf-G Executable retries to establish a connection to the Ninf-G client when the Ninf-G Executable could not connect to the Ninf-G client.
  • The timeout value of a sessions can be specified by a session attribute.
  • stdout and stderr of Ninf-G Executable can be put into files.
  • "broadcast" and "allocate" modifier are added to Ninf-G IDL for MPI.
    • "broadcast" : broadcast the variable to all nodes
    • "allocate" : allocate memory area for the variable on all nodes, but the value is not copied.
  • ng_gen accepts CPP options.
  • The compression for filename type variables is supported.
  • Ninf-G client can re-read the client configuration file on-the-fly. An API for re-read the client configuration file is added (grpc_config_file_read_np()).
  • Ninf-G client can exit without waiting JOB_DONE message from the Globus jobmanager.
  • Information of compression is added to grpc_session_info_t_np.
  • Arguments and results can be divided into blocks when they are transferred between Ninf-G client and Ninf-G Executable.
  • A tutorial document and sample programs are added into tutorial directory.
• Changes
  
  • The default value of loglevel was changed from 0 (None) to 2 (Error).
  • More detailed messages are put into log of Ninf-G Executable
  • The performance of sending/receiving data has been improved
  • Filename type variables are transferred without using GASS.
  • Implementation of grpc_probe_or() was changed to be compliant with the GridRPC API specification.
  • Ninf-G system checks the result field in the protocol data.
  • Ninf-G Executable does not catch SIGFEP, SIGSEGV, SIGILL and SIGQUIT.
  • log_filePath can take the following keywords:
    • %t: the time of creation of the file (yyyymmdd-hhmmss-MMM)
    • %p: process-ID
    • %h: hostname
  • changed the name of API for getting information of the last session (grpc_get_last_error_np() -> grpc_last_error_get_np())
• Fixed BUGs
  
  • job_startTimeout is ignored when transfer_argument is set to "nowait".
  • ninfg-user-env.sh script removes ${NG_PATH}* from $PATH.
  • *_handle_is_ready() freezes when non-thread Ninf-G Client get information of Remote Class from Ninf-G Executable
  • Ninf-G Executable failes in making a log directory when multiple Ninf-G Executables are invoked at the same time.
  • Ninf-G Executable does not return an error immediately when it fails in making a directory for logfiles.
  • Ninf-G client aborted when negative variable is set as job_startTimeout
  • save_sessionInfo did't accept "-1" and "0".
  • Ninf-G callback which has only OUT mode arguments causes an error.
  • Ninf-G callback with no arguments causes an error.
  • pthread Ninf-G Client sometimes freezes when it waits the completion of a session.
    
  • Remote Function with no arguments cannot be called by "Calls".
  • ng_gen can not process a big IDL file whose size is more than 4K Bytes.
  • ng_gen overwrites the file which is specified as the 2nd argument.
  • ng_gen detects an error if the callback type variable with no arguments is specified as the last argument of a Remote Function.
    
  • Java client cannot invoke Ninf-G Executable without LocalLDIF files.
  • Java client cannot process Ninf-G Expression which has more than 30 terms.
  • Java client occasionally returns incorrect results.
    
  • Shrink does not work correctly.
  • Invalid parameter of shrink causes an abort.
    
  • The number of MPI processes cannot be specified by a handle attribute of an object handle.
  • handle_attr_get() causes Segmentation Fault for an initialized handle attribute.
