OTHER (please specify)?
[Please indicate whether ACE/TAO/CIAO, your application, or both are affected.]
SYNOPSIS:
A call of Session_Container::get_objref blocks forever.
DESCRIPTION:
I'm running two clients simultaneously callings the methods acquireSession
and releaseSession of the CORBA component TSEC_CheckPoint ( please see
sample code in TSEC_CheckPoint_exec.cpp lines 233... and 283... and also
controller.cpp line 150... ) configured with realtime policies. After the
start of the second client the component TSEC_CheckPoint blocks in the
method Session_Container::get_objref ( please see the log file
DebuggerCallStack.log ).
The serious code line of TSEC_CheckPoint_exec.cpp is:
CORBA::Object_var obj = this->getObjRef( p_sessionImpl) ;
If only one client is calling acquireSession every thing works fine.
But if I start a second client which is calling acquireSession then the
block happens.
I'm using the patch from 20051612 for the files
Container_Base.cpp and Container_Base.h which I merge with the CIAO
version 047.
If i use CIAO version < 043 everythings works fine with no blocks.
REPEAT BY:
Please build the sample code:
- cd interfaces
- mwc.pl -type nmake
- nmake realclean clean depend all
- touch *.idl
- nmake
- cd SEC_CheckPoint
- mwc.pl -type nmake
- nmake realclean clean depend all
Please run the sample:
- cd descriptors
- start_da.bat
- start_am.bat
- start_test.bat
- start_testcase_1.bat
- start_testcase_2.bat
