WSDL2C:
--------
Key: AXIS2-3462
URL: https://issues.apache.org/jira/browse/AXIS2-3462
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: codegen
Affects Versions: 1.3
Environment: Windows XP
Reporter: Dave Meier
Priority: Blocker
Using:
org.apache.axis2.wsdl.WSDL2C -f -uri aewebservices70.wsdl -o
aewebservicesaxis70 -d adb -ss -sd
Problem:
In the serialize methods, the namespaces hashtable is being freed for many of
my adb objects, but one object that is nested frees this hashtable, then
returns and the calling serialize method then tries to use the freed table and
crashes.
Here's a code fragment showing the calling serialize method
(adb_NameValue_serialize(...)):
if (!_NameValue->is_valid_setValueBy)
{
/* no need to complain for minoccurs=0 element */
}
else
{
start_input_str = (axis2_char_t*)AXIS2_MALLOC(env->allocator,
sizeof(axis2_char_t) *
(4 + axutil_strlen(p_prefix) +
axutil_strlen("setValueBy") +
ADB_DEFAULT_DIGIT_LIMIT* 2));
end_input_str = (axis2_char_t*)AXIS2_MALLOC(env->allocator,
sizeof(axis2_char_t) *
(5 + ADB_DEFAULT_DIGIT_LIMIT + axutil_strlen("setValueBy")));
/*
* parsing setValueBy element
*/
sprintf(start_input_str, "<%s%ssetValueBy",
p_prefix?p_prefix:"",
(p_prefix && axutil_strcmp(p_prefix, ""))?":":"");
start_input_str_len = axutil_strlen(start_input_str);
sprintf(end_input_str, "</%s%ssetValueBy>",
p_prefix?p_prefix:"",
(p_prefix && axutil_strcmp(p_prefix, ""))?":":"");
end_input_str_len = axutil_strlen(end_input_str);
if(!adb_Set_Value_By_is_particle())
{
axutil_stream_write(stream, env, start_input_str, start_input_str_len);
}
adb_Set_Value_By_serialize(_NameValue->property_setValueBy,
env, current_node, parent_element,
adb_Set_Value_By_is_particle() || AXIS2_FALSE, namespaces,
next_ns_index); // THIS IS WHERE namespaces gets freed
if(!adb_Set_Value_By_is_particle())
{
axutil_stream_write(stream, env, end_input_str, end_input_str_len);
}
}
if(!(p_prefix = (axis2_char_t*)axutil_hash_get(namespaces,
"urn:aewebservicesaxis70", AXIS2_HASH_KEY_STRING))) // THIS IS WHERE it gets
used again and crashes
...
I will attach my wsdl file and the two adb files involved in the code above (
adb_NameValue.c which contains the above code and adb_Set_Value_By.c which
contains the adb_Set_Value_By_serialize(...) method that frees the namespaces
hashtable.
