[jira] [Updated] (AXIS2C-1628) axiom_node_create_from_buffer
modifies the buffer.
[ https://issues.apache.org/jira/browse/AXIS2C-1628?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmitry Utkin updated AXIS2C-1628:
---------------------------------
Attachment: echo_xml_from_buffer.tar.bz2
The patch axis2c-1628.patch causes axis2c server to crash, when axiom_node_create_from_buffer is used on server side.
echo_xml_from_buffer.tar.bz2 is a test service which reads axis2.xml (or any other xml you provide) and sends it as service response.
Before axis2c-1628.patch server does not crash, after that patch, it charshes.
To reproduce unpack echo_xml_from_buffer.tar.bz2 to samples/server/echo (replacing original files) compile and install.

> axiom_node_create_from_buffer modifies the buffer. Running this code
> char * xml = strdup("<foo>T1 & T2</foo>");
> AXIS2_LOG_DEBUG(env->log, AXIS2_LOG_SI, "before: %s", xml);
> axiom_node_create_from_buffer(env, xml);
> AXIS2_LOG_DEBUG(env->log, AXIS2_LOG_SI, "after: %s", xml);
> produces this output:
> before: <foo>T1 & T2</foo>
> after: <foo>T1 & T2; T2</foo>
> In some environments, if the strdup is omitted, a SEGV results, presumably on attempting to modify the string literal.
