memory leak at axis2_dep_engine_get_svc_dir
-------------------------------------------
Key: AXIS2C-1491
URL: https://issues.apache.org/jira/browse/AXIS2C-1491
Project: Axis2-C
Issue Type: Bug
Components: core/deployment
Affects Versions: 1.6.0
Environment: debian Linux
Reporter: H.Wang
I see the following memory leaks from the axis2c client stub code. When the
file_flag is set, "repos_path = axis2_dep_engine_get_svc_dir (dep_engine,
env);" allocates new memory, but at nowhere this memory is freed. It appears
that this leak occurs when AXIS2C_HOME points to the axis2.xml file instead of
the directory that holds axis2c.xml. We set AXIS2C_HOME to the axis2.xml file
because we have both axis2c server component and client sub on the same system,
and they need to point to different axis2c.xml files.

The leak comes from the following code,
AXIS2_EXTERN axis2_status_t AXIS2_CALL
axis2_arch_reader_process_svc_grp(
axis2_arch_reader_t * arch_reader,
const axutil_env_t * env,
axis2_char_t * file_name,
struct axis2_dep_engine * dep_engine,
axis2_svc_grp_t * svc_grp)
{
axis2_status_t status = AXIS2_FAILURE;
axis2_char_t *svc_grp_xml = NULL;
axis2_char_t *repos_path = NULL;
axis2_bool_t file_flag = AXIS2_FALSE;
AXIS2_PARAM_CHECK(env->error, file_name, AXIS2_FAILURE);
AXIS2_PARAM_CHECK(env->error, dep_engine, AXIS2_FAILURE);
AXIS2_PARAM_CHECK(env->error, svc_grp, AXIS2_FAILURE);
file_flag = axis2_dep_engine_get_file_flag (dep_engine, env);
if (!file_flag)
{
repos_path = axis2_dep_engine_get_repos_path(dep_engine, env);
svc_grp_xml = axutil_strcat(env, repos_path, AXIS2_PATH_SEP_STR,
AXIS2_SERVICE_FOLDER, AXIS2_PATH_SEP_STR,
file_name, AXIS2_PATH_SEP_STR, AXIS2_SVC_XML,
NULL);
}
else
{
repos_path = axis2_dep_engine_get_svc_dir (dep_engine, env);
svc_grp_xml = axutil_strcat (env, repos_path, AXIS2_PATH_SEP_STR,
file_name, AXIS2_PATH_SEP_STR, AXIS2_SVC_XML,
NULL);
}
