I would alway prefer a reference rather than a copy - specially
something like an array list. It is too costly yo copy.
Rather it is far better to keep track of stuff and release based on
life time. Inside the engine, for most of the cases, just a reference
serves the purpose.
I agree. But think about this. In the scenario I pointed out I'm
creating a completely new operation called create_seq_op.
app_msg_op_desc has flows and when it is freed those flows are freed. I
am not clear how to share these flows between the two operations and
avoid double free with the existing system. Could you please help me
with this case?

Hi,
In a situation like this
outflow = AXIS2_OP_GET_OUT_FLOW(app_msg_op_desc, env);
AXIS2_OP_SET_OUT_FLOW(create_seq_op, env, outflow);
Simply getting and setting the arraylist like this would leave to seg
faults
when both operations try to free the flow. Therefore I would like to
have
a new function in utilities
axis2_status_t AXIS2_CALL
axis2_utils_array_copy(
const axis2_env_t *env,
const axis2_array_list_t *array_to_copy)
{
int size = 0, i = 0;
axis2_array_list_t *new_array = NULL;
if(array_to_copy)
size = AXIS2_ARRAY_LIST_SIZE(array_to_copy, env);
if(size > 0)
{
new_array = axis2_array_list_create(env, 0);
if(!new_array)
{
AXIS2_ERROR_SET(env->error, AXIS2_ERROR_NO_MEMORY,
AXIS2_FAILURE);
return AXIS2_FAILURE;
}
}
for(i = 0; i < size; i++)
{
void *item = AXIS2_ARRAY_LIST_GET(array_to_copy, env);
AXIS2_ARRAY_LIST_ADD(new_array, env, item);
}
return new_array;
}
Or may be we can have this function in array_list it self
