[jira] [Commented] (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:comment-tabpanel&focusedCommentId=13621727#comment-13621727 ]
Alex Mantaut commented on AXIS2C-1628:
--------------------------------------
It seems that axiom_node_create_from_buffer() goes along carrying the reference to the buffer, and in the call to guththila_token_evaluate_references() the buffer gets modified.
The patch I've created just creates a local copy of the buffer for the reader to use. Other than that the modification of the buffer, the behaviour of the reader seemed correct.
I attach your test case to show how it is fixed... If possible I request the case to be incorporated to the tests...

> 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.
