RE : RE : [Tsp-devel] failure provider link on TSP_consumer_requ est_sample()

[ZXOPESOGE001, Ext]

Hi,

For my problem with TSP_consumer_request_sample(), i try  to do a step by step 
run inside a debugger
in order to see what happen after the buggy statement.In this way, i may be 
find the problem.
In tsp_consumer.c :
line 997 -> segmentation fault when i do the line > TSP_SSIList_copy(symbols, 
ans_sample->symbols);
In fact, the prevous line 991 > ans_sample = TSP_request_sample(&req_sample, 
otsp->server); ->probably return ans_sample=NULL

Moreover, i try to test a failure  provider link during a 
TSP_consumer_request_close().
To test that i have use this code:
    result = TSP_consumer_request_close(_scoe);
    MSG_TRACE(INOUT_LOW, "TSP_consumer_request_close" << result);
    if(TSP_STATUS_OK!=result) 
    {
      MSG_SW_ERROR("SCOE " << MSG_PTR(_scoeName) << " : Function 
TSP_consumer_request_close failed ");
      throw OCEIF_TSP_Exception(OCEIF_TSP_DISCONNECTION_PB_IDNB,
                              OCEIF_TSP_DISCONNECTION_PB_NAME,
                              OCEIF_TSP_DISCONNECTION_PB_REASON);  
    }

I have the TSP error   --> 
ERROR||/home/intocv61/VAla/TSP/sources/src/core/rpc/tsp_client.c##TSP_request_close##211:
 : RPC: Unable to receive; errno = Connection reset by peer
That's OK but the result returns by TSP_consumer_request_close() is 
TSP_STATUS_OK 
May be a retcode is not update in TSP_consumer_request_close() in tsp_consumer.c

if you have time, can you correct the TSP code. 

thank you in advance

OK then you have to file a bug in Savannah with just that.
You may add url the ML archive:
http://lists.nongnu.org/archive/html/tsp-devel/2007-04/msg00046.html

I currently do not have much time to reproduce and track this bug
may be someone else out there may investigate?

Nevertheless if you do not see any trace after the request_sample statement
the thread running that code should have died?

Is your application multi-threaded or multi-process?
If yes did you call any of the:
  pthread_cleanup_push/pop
  pthread_atfork
  atexit
and the like function

Did you try to do a step by step run inside a debugger
in order to see what happen after the buggy statement?
