commit d492a16d24a8e57032132007114096704fc9ff91 Author: Robert Lazarski <[email protected]> AuthorDate: Mon Jan 12 15:53:48 2026 -1000 Add defensive xsd:any type handling to native WSDL2C generator (AXIS2C-1580) When deserializing xsd:any elements, axiom_element_get_qname() returns NULL because xsd:any elements don't have a fixed qname. The generated deserialization code now checks for NULL element_qname before performing qname comparison, preventing crashes when processing extensible schemas. Changes: - Add schema parsing to detect xsd:any elements in WSDL - Generate safe deserialization code with NULL qname checks - Add unit tests for xsd:any detection and NULL qname handling Co-Authored-By: Claude Opus 4.5 <[email protected]> --- tools/codegen/native/include/wsdl2c_native.h | 17 + tools/codegen/native/src/stub_generator.c | 20 +- tools/codegen/native/src/wsdl_parser.c | 139 +++++++++ tools/codegen/native/test/Makefile.am | 1 + .../native/test/include/adb_test_framework.h | 16 + tools/codegen/native/test/src/adb_test_framework.c | 1 + .../native/test/src/test_axis2c_1580_any_type.c | 346 +++++++++++++++++++++ 7 files changed, 539 insertions(+), 1 deletion(-) diff --git a/tools/codegen/native/include/wsdl2c_native.h b/tools/codegen/native/include/wsdl2c_native.h index c3c92cca2..522df7c4e 100644 --- a/tools/codegen/native/include/wsdl2c_native.h +++ b/tools/codegen/native/include/wsdl2c_native.h @@ -135,6 +135,21 @@ typedef struct wsdl2c_options { axis2_bool_t sync_only;
