Source code of test application is attached to this ticket.
Import the 'Test' class and create some objects of it.
root@SC-1:~# immcfg -f test_class.xml
root@SC-1:~# immpopulate -p 10 Test
Run the OI. The OI has a sleep of 7 seconds in SaImmOiRtAttrUpdateCallbackT.
root@SC-1:~# ./test_oi &
Try to read all objects of 'Test' class
root@SC-1:~# ./test_search
IMMND crashes when receiving respose from the OI.
Apr 22 11:27:51 SC-2 osafimmnd[431]: immnd_evt.c:1080: search_req_continue:
Assertion 'strncmp((const char *)rsp->objectName.buf, (const char
*)reply->runtimeAttrs.objectName.buf, rsp->objectName.size) == 0' failed.
-----
Analysis:
When the upcall to OI is timed out, IMMND erases the Continuation from the
sSearchReqContinuationMap but it still keeps the search-node (and the searchOp).
On the search client, after getting timeout, it doesn't finalize the search
handle and continues to do SearchNext().
That makes the searchOp in IMMND pop out a new object and store it to
mLastResult.
When the response from OI arrives at IMMND, it fails to assert because a new
object in searchOp has been popped out.
