Hello
The following snippet taken from a generated deserialize method may lead to a
memory leak:
axutil_hash_index_t *hi;
for (hi = axutil_hash_first(attribute_hash, env); hi; hi =
axutil_hash_next(env, hi))
{
axutil_hash_this(hi, &key, NULL, &val);
if(!strcmp((axis2_char_t*)key, "someName"))
{
parent_attri = (axiom_attribute_t*)val;
break;
}
}
hi gets allocated in axutil_hash_first.
hi is freed in axutil_hash_next, but only when the end of the hash array has
been reached. However, in the code above, we exit the for loop when we find the
desired hash entry. In such a case, axutil_hash_next never gets to the and of
the hash array and thus hi is never freed.
A possible fix might be to change the CADBBeanTemplateSource.xsl so that the
generated code looks something like this:
axutil_hash_index_t *hi;
for (hi = axutil_hash_first(attribute_hash, env); hi; hi =
axutil_hash_next(env, hi))
{
axutil_hash_this(hi, &key, NULL, &val);
if(!strcmp((axis2_char_t*)key, "someName"))
{
parent_attri = (axiom_attribute_t*)val;
// added from here
AXIS2_FREE(env->allocator, hi);
// added up to here
break;
}
}
