[jira] Created: (AXIS2C-19) There is something wrong in the ops
hash map in service
There is something wrong in the ops hash map in service
-------------------------------------------------------
Key: AXIS2C-19
URL: http://issues.apache.org/jira/browse/AXIS2C-19
Project: Axis2-C
Type: Bug
Components: core/description
Reporter: Samisa Abeysinghe
Priority: Critical
Fix For: M0.3
The following piece of code crashes unexpectedly: Note that ops count is one, but it tries to read a second op.
for (hi = axis2_hash_first (svc_map, &env);
NULL != hi; hi = axis2_hash_next (&env, hi))
{
axis2_hash_t *ops= NULL;
axis2_hash_this(hi, NULL, NULL, &service);
ops = AXIS2_SVC_GET_OPS(((axis2_svc_t *)service), &env);
if(ops)
{
printf("ops count = %d\n", axis2_hash_count(ops));
axis2_hash_index_t *hi2 = NULL;
void *op = NULL;
axis2_char_t *oname = NULL;
int count = 0;
for(hi2 = axis2_hash_first(ops, &env); hi2; axis2_hash_next(&env, hi2))
{
printf ("count = %d \n", count++);
if (!hi2)
break;
axis2_hash_this(hi2, NULL, NULL, &op);
if (op)
{
axis2_qname_t *qname = NULL;
qname = AXIS2_OP_GET_QNAME((axis2_op_t *)op, &env);
oname = AXIS2_QNAME_GET_LOCALPART(qname, &env);
printf("op name = %s\n", oname);
}
}
}
else
printf("ops count = zero\n");
}

[jira] Closed: (AXIS2C-19) There is something wrong in the ops hash
map in service
Posted by "Samisa Abeysinghe (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/AXIS2C-19?page=all ]
Samisa Abeysinghe closed AXIS2C-19:
-----------------------------------
Resolution: Fixed
The problem was in the for loop.
for(hi2 = axis2_hash_first(ops, &env); hi2; axis2_hash_next(&env, hi2))
axis2_hash_next(&env, hi2) should be hi2 = axis2_hash_next(&env, hi2)
