From f0510d2f90467de8e8f260b47d79a9baaf9bef17 Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Thu, 17 Sep 2009 07:15:29 +0200 Subject: Start tracking XSD with git --- NEWS | 1048 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 1048 insertions(+) create mode 100644 NEWS (limited to 'NEWS') diff --git a/NEWS b/NEWS new file mode 100644 index 0000000..60f7071 --- /dev/null +++ b/NEWS @@ -0,0 +1,1048 @@ +Version 3.3.0 + + * When built with Xerces-C++ 3-series, enable handling of multiple + imports for the same namespace. Before, all subsequent imports for + a namespace were ignored which caused error in some schemas. + + * Warning id's have changed to start with a letter identifying the + component issuing the warning. F - compiler frontend, D - compiler + driver, P - C++/Parser mapping, T - C++/Tree mapping. + + C++/Tree + + * New option, --generate-element-type, triggers generation of types + instead of parsing/serialization functions for root elements. This + is primarily useful to distinguish object models with the same root + type but with different root elements. For more information refer + to the messaging example and Section 2.9.1, "Element Types" in the + C++/Tree Mapping User Manual. To support customization of the + element type naming the --element-type-regex option has been added. + See the NAMING CONVENTION section in the compiler command line manual + (man pages) for details. + + * New option, --generate-element-map, triggers generation of a root + element map. The element map allows uniform parsing and serialization + of multiple root elements. This option can only be used together with + --generate-element-type. For more information refer to the messaging + example and Section 2.9.2, "Element Map" in the C++/Tree Mapping + User Manual. + + * New option, --export-xml-schema, causes the compiler to export/import + types in the XML Schema namespace using the export symbol provided + with the --export-symbol option. + +Version 3.2.0 + + * New option, --disable-warning, disables printing of a warning with + the specified id. Specifying 'all' for the warning id disables all + warnings. + + * New options, --export-maps and --import-maps, provide support for + splitting a polymorphic type hierarchy across several Win32 DLLs. + See the compiler command line manual (man pages) for details. + + C++/Tree + + * During serialization the generated code automatically assigns + generic prefixes (p1, p2, etc) to XML namespaces used in the + vocabulary and for which no custom prefix-namespace mapping + was provided via the xml_schema::namespace_infomap argument. + The xml_schema::namespace_infomap argument in the serialization + functions is now default-initialized to an empty map. The + xml_schema::no_namespace_mapping and xml_schema::xsi_already_in_use + exceptions have been removed. + + * New example, performance, measures the performance of parsing and + serialization. This example also shows how to structure your code + to achieve the maximum performance for these two operations. + + * New example, xpath, shows how to use the C++/Tree mapping together + with XPath. + + * New options, --one-accessor-regex, --opt-accessor-regex, + --seq-accessor-regex, --one-modifier-regex, --opt-modifier-regex, + and --seq-modifier-regex, allow specification of transformations + for accessor and modifier function names for elements and attributes + with specific cardinalities. For more information see the NAMING + CONVENTION section in the compiler command line manual (man pages). + + * Support for comparison (--generate-comparison) and printing + (--generate-ostream) of polymorphic object models. + + * New serialization flag, xml_schema::flags::dont_pretty_print, + disables extra spaces and new lines that make the resulting XML + slightly bigger but easier to read. + + * New example, custom/double, shows how to customize parsing and + serialization code for the xsd:double XML Schema built-in type. + It can be used as a guide on how to customize built-in XML Schema + types that are mapped to fundamental C++ types. + + * Support for fractionDigits and totalDigits facets in serialization + of types derived from xsd:decimal. + + * New set of compile-time macros that control how the xsd:float, + xsd:double, and xsd:decimal types are serialized. The following + macros control the format: + + XSD_CXX_TREE_FLOAT_FIXED + XSD_CXX_TREE_FLOAT_SCIENTIFIC + XSD_CXX_TREE_DOUBLE_FIXED + XSD_CXX_TREE_DOUBLE_SCIENTIFIC + + The following macros control the precision: + + XSD_CXX_TREE_FLOAT_PRECISION_MAX + XSD_CXX_TREE_FLOAT_PRECISION + XSD_CXX_TREE_DOUBLE_PRECISION_MAX + XSD_CXX_TREE_DOUBLE_PRECISION + XSD_CXX_TREE_DECIMAL_PRECISION_MAX + XSD_CXX_TREE_DECIMAL_PRECISION + + If the *_PRECISION_MAX macro is defined then the maximum number of + potentially significant decimal digits that the type can represent + is used. Otherwise, if the *_PRECISION macro is defined then its + value is used. By default the precision is set to the number of + decimal digits that the type can represent without change. For + more information on these options, refer to the following paper: + + http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1822.pdf + + The old macro, XSD_FP_ALL_DIGITS, that was equivalent to defining + all three *_PRECISION_MAX macros has been removed. + + An alternative to using these macros is to customize the floating + point type as shown in the custom/double example. + + * An additional constructor is generated in situations where a type + contains one or more required element of complex type (that is, + it itself contains elements or attributes). In this constructor, + initializers for such elements are passed as std::auto_ptr and the + newly created instance is directly initialized with and assumes + ownership of the pointed to objects. This constructor is a logical + addition to the non-copying modifiers that were introduced in the + previous version. + + * Extra conversion operators in the fundamental_base class template + which is used to emulate inheritance from fundamental types are now + disabled by default since they cause problems on several compilers. + To enable them compile your code with the XSD_TREE_EXTRA_FUND_CONV + macro defined. + + C++/Parser + + * New options, --generate-xml-schema and --extern-xml-schema, trigger + generation of the mapping for the XML Schema namespace to a separate + header file and inclusion of that header into other generated header + files instead of generating the necessary declarations inline, + respectively. See the compiler command line manual (man pages) for + details. + + * New example, performance, measures the performance of XML parsing. + This example also shows how to structure your code to achieve the + maximum performance for this operation. + + * Type map files can now include comments. A comment starts with # + and ends with a new line or end of file. To specify a name that + contains # enclose it in "". + + * In type map files the optional argument type now defaults to the + return type if the return type ends with * or & (that is, it is + a pointer or a reference) and 'const return type&' otherwise. + + * The interface for polymorphic parsing has been simplified. Calling the + *_parser() functions multiple times to specify several parsers is no + longer supported. Instead you need to pass the xml_schema::parser_map + object which contains the parsers. For more information refer to + Section 5.4, "Support for Polymorphism" in the C++/Parser Mapping + Getting Started Guide. + + * The use of virtual inheritance has been reduced which results in a + much smaller object code size (more than factor of 2 on some tests) + and faster C++ compilation with less RAM used. + + * The low-level Expat-specific parsing API (parse_begin() and parse_end()) + has been extended to provide XML and XML Schema error translation to + exceptions or error handler calls. See Section 7.2, "Expat Document + Parser" in the C++/Parser Mapping Getting Started Guide for more + information. + +Version 3.1.0 + + * New option, --file-per-type, triggers generation of a separate set + of C++ files for each type defined in XML Schema. This compilation + mode is primarily useful when some of your schemas cannot be compiled + separately or have cyclic dependencies which involve inheritance. + Other new options that are useful in this compilation mode are + --type-file-regex, --type-file-regex-trace, and --file-list. See the + compiler command line manual (man pages) for more information. + + * New option, --options-file, allows additional command line options + to be provided in files, with one option per line. + + * New option, --reserved-name, allows insertion of additional names + with optional replacements to the list of names that should not be + used as identifiers. See the compiler command line manual (man pages) + for details. + + * New options, --location-map, --location-regex, and + --location-regex-trace, allow re-mapping of schema locations + specified in the include and import elements without modifying the + schema files. See the compiler command line manual (man pages) for + more information. + + * New option, --guard-prefix, allows specification of a prefix that + should be added to generated header inclusion guards. + + * New option, --file-list, triggers creation of a file with a list of + generated C++ files. This option is primarily useful in the file-per- + type compilation mode (--file-per-type) to create a list of generated + C++ files, for example, as a makefile fragment. Other new options + that are useful with --file-list are --file-list-prologue, + --file-list-epilogue, and --file-list-delim. See the compiler command + line manual (man pages) for more information. + + * Support for the upcoming Xerces-C++ 3.0.0 release. + + C++/Tree + + * New option, --generate-intellisense, triggers generation of workarounds + for IntelliSense bugs in Visual Studio 2005 (8.0). When this option is + used, the resulting code is slightly more verbose. IntelliSense in + Visual Studio 2008 (9.0) does not require these workarounds. Support + for IntelliSense in Visual Studio 2003 (7.1) is improved with this + option but is still incomplete. + + * New options, --type-naming and --function-naming, allow specification + of the type and function naming conventions that should be used in the + generated code. Supported values for --type-naming are: knr (K&R), ucc + (upper-camel-case), and java. Supported values for --function-naming + are: knr (K&R), lcc (lower-camel-case), and java. For more information + see the NAMING CONVENTION section in the compiler command line manual + (man pages). + + * New options, --type-regex, --accessor-regex, --modifier-regex, + --parser-regex, --serializer-regex, and --enumerator-regex, allow + specification of transformations for type, accessor function, + modifier function, parsing function, serialization function, and + enumerator names in order to produce the generated code using a + custom naming convention. For more information see the NAMING + CONVENTION section in the compiler command line manual (man pages). + + * Generated list classes now provide a complete set of constructors and + conform to the standard C++ sequence interface. + + * String-based types now provide two extra constructors that expect a + C string and std::string as their arguments. This allows direct + initialization of string-based types from string literals. + + * New implementations of the XML Schema date/time types (date, dateTime, + duration, gDay, gMonth, gMonthDay, gYear, gYearMonth, and time) that + represent the information in the numerical form. + + * New binary serialization examples: binary/boost, which shows how to + save/load the object model to/from a custom format using the Boost + serialization library as an example, and binary/xdr, which shows how to + save/load the object model to/from XDR (eXternal Data Representation) + binary format using the XDR API provided as part of Sun RPC. + + * The non-copying modifier functions can now be used to assemble object + models from scratch. For more information see Section 4.4, "Creating + the Object Model from Scratch" in the C++/Tree Mapping Getting Started + Guide as well as Section 2.8, "Mapping for Local Elements and Attributes" + in the C++/Tree Mapping User Manual. + + * Doxygen documentation was added to the XSD runtime for the built-in XML + Schema types, exceptions, etc. This allows linking of the generated + documentation to the XSD runtime documentation using the Doxygen tags + mechanism. The Doxygen configuration file for the XSD runtime is + provided in the documentation/cxx/tree/reference/ directory. + + * Support for customization of anyType. Because anyType is a base type + for every generated type, customizing it allows one to implement custom + functionality that spans the entire type system. See the comments + example in the examples/cxx/tree/custom/ directory. + + * New option, --omit-default-attributes, triggers generation of extra + checks that exclude attributes with default and fixed values from the + serialized XML documents. + + * The parsing functions that used to read from DOMInputSource were changed + to use InputSource to ease support of Xerces-C++ 3 and 2 series in the + same code base. + + * The parsing function that used to parse DOMDocument* was changed to + parse xml_schema::dom::auto_ptr& instead. If the keep_dom + and own_dom flags are specified then this parsing function resets the + passed automatic pointer and the returned object model assumes + ownership of the DOM document. xml_schema::dom::auto_ptr is a simple + automatic pointer for Xerces-C++ DOM with the same interface as + std::auto_ptr. + + * The xml_schema::tree_node_key DOM user data key was moved to + xml_schema::dom::tree_node_key. + + C++/Parser + + * New option, --generate-polymorphic, triggers generation of polymorphism- + aware code. This option should be used on XML vocabularies which use + xsi:type and/or substitution groups. For more information see Section + 5.4, "Support for Polymorphism" in the C++/Parser Mapping Getting + Started Guide we well as the polymorphism and polyroot examples in the + examples/cxx/parser/ directory. + + * The date/time types (date, dateTime, gDay, gMonth, gMonthDay, gYear, + gYearMonth, and time) now represent time zone in the numerical form. + + * In order to support parsing of polymorphic XML documents, the signatures + of the start_* functions (_start_element, _start_any_element, and + start_root_element) have changed to include a third argument of type + const ro_string*. This argument contains the resolved type name and + namespace in case the xsi:type attribute was specified. + +Version 3.0.0 + + * Anonymous type morphing (automatic type naming) is now performed by + default in both mappings. The --morph-anonymous option does not have + any effect but is preserved for backwards compatibility. A new option, + --preserve-anonymous, disables anonymous type morphing. This option is + useful together with --show-anonymous if you want to make sure your + schemas do not have any anonymous types. + + * A number of bugs fixed in both C++/Tree and C++/Parser mappings. + + C++/Tree + + * The new C++/Tree Mapping Getting Started Guide is available in the + documentation/cxx/tree/guide/ directory. + + * The type definitions for local elements and attributes in the form + name::type have been changed to name_type. For example, an element + bar in type foo with maxOccurs="unbounded" used to have its iterator + type defined as foo::bar::iterator. With this change it becomes + foo::bar_iterator. Furthermore, the container type name for sequence + elements has changed from foo::bar::container to foo::bar_sequence + and for optional elements and attributes from foo::bar::container + to foo::bar_optional. This is a backwards incompatible change and + may require application code adjustments (the C++ compiler will + pinpoint the affected places). + + * New option, --generate-doxygen, triggers generation of documentation + comments suitable for extraction by the Doxygen documentation system. + Documentation from annotations is added to the comments if present in + the schema. + + * New option, --generate-wildcard, triggers generation of the new + wildcard (any and anyAttribute) mapping. This mapping represents the + content matched by wildcards as DOM fragments. For more information on + the new mapping see Section 2.12, "Mapping for any and anyAttribute" + in the C++/Tree Mapping User Manual as well as the wildcard example in + the examples/cxx/tree/ directory. + + * New option, --generate-comparison, triggers generation of comparison + operators (== and !=) for complex types. Comparison is performed + memberwise. + + * Support for the RPC XDR binary stream in addition to ACE CDR. + + * New constructor is generated for complex types with ultimate bases + that are simple types and can be default-initialized. This constructor + includes initializers for all required members but omits the initializer + for the base type. See Section 2.7, "Mapping for Complex Types" in the + C++/Tree Mapping User Manual for more information. + + * Support for polymorphic binary serialization and extraction. Note that + the semantics of the --generate-insertion and --generate-extraction + options has changed. See the the compiler command line manual (man + pages) for details. + + * New parsing function with the DOMDocument* argument and the own_dom + flag allow the tree to assume the ownership of the DOM document + being parsed when DOM association is requested (keep_dom flag). + See the C++/Tree Mapping User Manual for more information. + + * New example, multiroot, shows how to handle XML vocabularies with + multiple root elements. + + * New example, caching, shows how to parse several XML documents while + reusing the underlying XML parser and caching the schemas used for + validation. + + * The mapping of built-in XML Schema type decimal has changed from + long double to double. The old mapping can be obtained by providing + a custom mapping for this type. + + * The xml_schema::errors type which is used in the xml_schema::parsing + and xml_schema::serialization exceptions has been renamed to + xml_schema::diagnostics and extended to include warnings in addition + to errors. + + * Serialization operators now clear the element being serialized to from + existing child nodes and attributes (except for special attributes such + as prefix-namespace mappings, etc.). + + * Improved built-in type parsing, including support for normalization and + whitespace collapsing. + + * Optimizations for the generated code size and compilation time, + including space optimizations for polymorphic parsing and + serialization. Optimizations for XML parsing speed. + + C++/Parser + + * The C++/Parser mapping have been significantly redesigned. See the new + Getting Started Guide in documentation/cxx/parser/guide/ for details. + + * The new C++/Parser Mapping Getting Started Guide is available in the + documentation/cxx/parser/guide/ directory. + + * The mapping now provides parser implementations for all built-in XML + Schema types. See Chapter 6, "Built-In XML Schema Type Parsers" in + the C++/Parser Mapping Getting Started Guide for more information. + + * The mapping now supports automatic generation of sample parser + implementations and a test driver. The --generate-noop-impl option + triggers generation of a sample implementation with empty function + bodies. The --generate-print-impl option triggers generation of a + sample implementation that prints the data stored in XML to STDOUT. + The --generate-test-driver option trigger generation of a test driver. + For more information on this feature see the compiler command line + manual (man pages) and the generated example in the examples/cxx/parser/ + directory. Other relevant options include: --force-overwrite, + --root-element-first, --root-element-last, and --root-element. + + * New example, wildcard, shows how to parse the XML data matched by + XML Schema wildcards (any and anyAttribute). + + * The xml_schema::document parser has been extended with overridable + virtual functions start_root_element and end_root_element to support + parsing of XML vocabularies with multiple document roots. See the + multiroot example in the examples/cxx/parser/ directory for more + information. + + * The xml_schema::errors type which is used in the xml_schema::parsing + exception has been renamed to xml_schema::diagnostics and extended to + include warnings in addition to errors. + +Version 2.3.1 + + * The compiler is now capable of translating multiple schemas with + one invocation. + + * New option, --sloc-limit, allows one to limit the amount of the + generated code. + + * New option, --proprietary-license, instructs the compiler not to + include the GPL banner in each generated file. Instead a short + notice about a required proprietary license is generated. You + should not use this option unless you have obtained a proprietary + license from Code Synthesis Tools CC. + + * The default encoding for the 'char' character type is now UTF-8. + To get the previous behavior (local code page via the Xerces-C++ + transcode functions) define the XSD_USE_LCP preprocessor macro + when compiling your source code. + + C++/Tree + + * The --parts option has been improved to split generated code more + evenly by analyzing the complexity of the generated schema constructs. + + * Ability to customize serialization, std::ostream, and binary + insertion/extraction operators. See examples/cxx/tree/custom/wildcard + for an example on how to handle XML Schema wildcards (xsd:any and + xsd:anyAttribute) by customizing the parsing constructor and + serialization operators. + + * Optimizations for the run-time memory consumption. + + * Optimizations for space in the generated code. + + * Number of bug fixes. + + C++/Parser + + * Proper handling of an xsd:any nested content. Nested elements, + attributes, and text are reported via _any_* hooks of the current + parser. + + * Number of bug fixes, mostly in the generated validation code. + + +Version 2.3.0 + + * Name conflicts across type inheritance hierarchies are now detected + and resolved via name escaping. + + C++/Tree + + * New option, --suppress-parsing, suppresses generation of the parsing + constructors and functions. This can be used to minimize the generated + code footprint when parsing from XML is not used. + + * New option, --generate-forward, triggers generation of a forward + declaration header file for types defined in the schema. A set of + --fwd-* options that control the resulting file name as well as + prologue and epilogue code are available. + + * New option, --generate-xml-schema, triggers generation of the mapping + for the XML Schema namespace to a separate header file. See the man + pages for details and examples/cxx/tree/custom/calendar for an example. + + * New option, --extern-xml-schema, triggers inclusion of a header + file for the XML Schema namespace instead of generating the + necessary declarations inline. See the man pages for details and + examples/cxx/tree/custom/calendar for an example. + + * New options, --custom-type and --custom-type-regex, instruct the + compiler to use custom C++ type for a type defined in the schema. + The standard mapping can still be generated (with a different name) + usually to be used as a base. Built-in XML Schema types can be + customized using this mechanism. See the man pages for details and + examples/cxx/tree/custom/* for examples. + + * The generated parsing constructors and serialization operators have + been changed to use the Xerces-C++ DOM elements and attributes + instead of the internal wrapper types. This should provide easier + integration with other code and libraries that use the Xerces-C++ + DOM types such as Berkeley DB XML. + + * New example, examples/cxx/tree/dbxml, shows how to use the C++/Tree + mapping on top of the Berkeley DB XML database. + + C++/Parser + + * Validation of the attribute structure in the generated code. + + * Validation of the character content models including mixed content in + the generated code. + + * Validation of the built-in XML Schema types. + + * Optimizations for space and time in the generated code. In particular + data coping during parsing and validation was significantly reduced. + + +Version 2.2.0 + + * Detection of a version mismatch between the generated code and + the runtime. + + C++/Tree + + * Escaping of a global element name that conflicts with a global type + name. This is a backwards-incompatible change. Previous versions + map them to the same name. + + * New options, --generate--insertion and --generate-extraction, + trigger generation of (binary) data representation stream + insertion and extraction operators, respectively. This allows + one to serialize/deserialize in-memory representation to/from + data representation streams such as XSD, CDR, etc. ACE CDR + streams are supported out of the box (see the binary example). + User-supplied streams can be used via an adaptation layer. + + * New serialization flag, no_xml_declaration, instructs the XML + serialization functions to omit an XML declaration. This is useful + for streaming serialization (see the streaming example). + + * Optimizations to reduce generated code size. + + + C++/Parser + + * New options, --generate-validation and --suppress-validation, + trigger and suppress generation of the validation code, + respectively. The validation code is the implementation of the + XML Schema validation in the generated code (also known as + "perfect" parser). In this version validation of the element + structure has been implemented. + + * New architecture for underlying XML parsers. This is a backwards- + incompatible change. Existing applications will have to be + modified. See examples for details. + + +Version 2.1.1 + + C++/Tree + + * New option, --namespace-map, allows direct mapping of XML Schema + namespaces to C++ namespaces without the use of regular expressions. + + * Further optimizations in the container code and enum mapping to + reduce generated code size. + + * Number of bug fixes in the generated code. + + + C++/Parser + + * New option, --namespace-map, allows direct mapping of XML Schema + namespaces to C++ namespaces without the use of regular expressions. + + +Version 2.1.0 + + * Automatic handling of forward inheritance. XML Schema allows + inheritance from yet undefined types while it is illegal to do + so in C++. Now the translator automatically handles forward + inheritance by re-arranging the schema during compilation. + + + C++/Tree + + * New enum mapping with support for inheritance. Enumerators are + now parsed using binary search instead of linear search. + + * Associated DOM nodes now retain "back" pointers to tree nodes. + + * Optimizations to reduce generated code size. + + + C++/Parser + + * Specialization for void. You can now use void as a hook argument + type if you don't want to pass any data between parsers. + + * Support for re-use of implementations of base parsers in derived + parsers using the mixin C++ idiom. See the examples/cxx/parser/mixin + for more information. + + * Support for uninitialized parser. If you don't provide a parser + for element/attribute, that element/attribute will be ignored + during parsing. + + +Version 2.0.0 + + * New cardinality calculator. This improves support for schemas that + use complex structures with repeated elements, e.g., + + + + + + + + + + + + + + + + * New identifier escaping code. With this feature xsd generates proper + code for schemas that use the same name for an element and an attribute + in the same type or use several elements/attributes with different + qualified names but with the same local name, e.g., + + + + + + + + + + + + + + + + + + + + + + + + + + C++/Tree + + * New option, --generate-polymorphic, triggers generation of + polymorphism-aware code. Before this release xsd used to always + generate polymorphism-aware code. However, it appears to be quite + wasteful in terms of the generated code size (up to 40%). You will + now need to explicitly specify this option if you use substitution + groups or xsi:type. A warning is issued if this option is not + specified but the schema makes use of substitution groups. + + * New options, --root-element-first, --root-element-last, + --root-element-all, --root-element-none, and --root-element, control + generation of parsing and serialization functions. With these options + you can avoid generating extra code for global elements that are not + document roots. See the man pages for details. + + * New options, --parts and -parts-suffix, allows you to split generated + source code into a number of parts. This is useful when translating + large, monolithic schemas and a C++ compiler is not able to compile + the resulting source code at once (usually due to insufficient memory). + + * New option, --generate-default-ctor, triggers generation of default + constructors even for types that have required members. Required + members of an instance constructed using such a constructor are not + initialized and accessing them results in undefined behavior. Thanks + to Jean-Francois Dube for suggesting this + feature. + + * New option, --generate-from-base-ctor, triggers generation of + constructors that expect an instance of a base type followed by all + required members. Thanks to Jean-Francois Dube + for suggesting this feature. + + * Information scopes for attributes and elements with default/fixed values + now define the public static default_value function which allows one to + obtain the default/fixed value for the element/attribute. Thanks to + Dave Moss for suggesting this feature. + + * MSVC 7.1 has a limit on the length of the "if else if" chain. This + results in ICE when compiling generated code for enumerations with + a large number of values. This version addresses this issue. Thanks + to Cyrille Chépélov for reporting this and + suggesting a fix. + + + C++/Parser + + * The parser construction API has changed. Now, for element 'foo', + the name of the parser modifier function is 'foo_parser'. Likewise, + operator() for setting all parsers at once has been changed to the + 'parsers' function. + + +Version 1.9.0 + + C++/Tree + + * The size modifier function in the base64_binary and hex_binary + built-in types automatically adjusts capacity if needed. + + * More internal names (names that start with _xsd_) were made + private or protected. + + C++/Parser + + * Typedef for the parser base in the xml_schema namespace. + + C++/Parser-E + + * C++/Parser mapping optimized for embedded systems. For now it + is equivalent to 'cxx-parser --xml-parser expat'. + + +Version 1.8.0 + + * Moved to the build 0.2 series. + + C++/Tree + + * Support for default and fixed values in attributes. An optional + attribute with a default or fixed value is mapped to the One + cardinality class instead of the Optional cardinality class. + + * Mapping for base64Binary and hexBinary has improved. Now these + types support a basic buffer abstraction and perform automatic + encoding and decoding. + + * Internal names are protected. We've noticed (via bug reports) a + wide use of internal names (names that start with _xsd_) in user + code. This is not portable and instead you should use public + names. To prevent this from happening in the future we've made + all internal names protected. + + C++/Parser + + * Support for Expat as the underlying XML parser in addition to + Xerces-C++. This allows one to use the C++/Parser mapping in + memory-constrained environments such as embedded systems. To + select Expat instead of Xerces-C++ (default) add + '--xml-parser expat' to the command line. At the moment only + 'char' (UTF-8) is supported as the base character type when + Expat is selected. + + * The invalid_instance exception has been renamed to parsing. + + * Generic error_handler interface has been added in addition + to Xerces-C++-specific DOMErrorHandler. It allows you to + handle parsing errors and warnings without having to deal + with Xerces-C++ specifics. + + * The default error handling behavior has changed in parsing + functions. Instead of printing errors and warnings to STDERR, + the errors are now collected and thrown as part of the parsing + exception. + + * In parsing functions, the name, namespace arguments order has + been reversed to be consistent with the one used in parsing + hooks. + +Version 1.7.0 + + * Number of bug fixes in libxsd and the generated code. + + C++/Tree + + * Comprehensive XML Schema C++/Tree Mapping User Manual. + + * Basic support for union. A simple type that is defined using + derivation by union is mapped to a C++ class that derives from + string. + + * The _clone function has its arguments default-initialized. + + * The invalid_instance exception has been renamed to parsing. + + * Generic error_handler interface has been added in addition + to Xerces-C++-specific DOMErrorHandler. It allows you to + handle parsing/serialization errors and warnings without + having to deal with Xerces-C++ specifics. See the user + manual for more information. + + * The default error handling behavior has changed in parsing + and serialization functions. Instead of printing errors and + warnings to STDERR, the errors are now collected and thrown + as part of the parsing/serialization exception. See the user + manual for more information. + + * The optional and sequence containers now support operators ==, + !=, <, >, <=, and >=. + + * Flags argument has been added to serialization functions. The + only flag that is currently supported is dont_initialize. + + * Generated code cleanups. + + C++/Parser + + * Basic support for union. A simple type that is defined using + derivation by union is mapped to a C++ class template that + is just an alias for the generic parser. You are expected to + override the _characters function in your implementation. + + * Properties argument to parsing functions which allows to + programmatically specify schemas for instance document + validation. + + * Flags argument to parsing functions. The following flags + are supported: + + dont_validate - do not validate instance documents + dont_initialize - do not initialize the Xerces-C++ runtime + +Version 1.6.0 + + * Number of bug fixes in libxsd and the generated code. + + C++/Tree + + * Support for xsi:type and substitution groups in parsing and + serialization. See examples/cxx/tree/polymorphism for a code + sample. + + * Properties argument to parsing functions which allows to + programmatically specify schemas for instance document + validation. + + * Extra checks in parsing code which prevents construction + of inconsistent in-memory representation from invalid + instance documents. Should be useful when validation is + disabled. + + * Accessors and modifier were made normal member functions. + Before they were implemented via functors. + + * Workaround for g++-3.3 bug# 16650: + + http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16650 + + C++/Parser + + * All "service" functions were renamed to start with '_'. + This should prevent hiding of service functions by + elements/attributes with the same names. + +Version 1.5.0 + + * Number of bug fixes in libxsd and the generated code. + + C++/Tree + + * Basic support for inheritance-by-restriction in complex types. + + * The following parsing flags have been introduced: + + keep_dom - keep association with underlying DOM nodes + dont_validate - do not validate instance documents + dont_initialize - do not initialize the Xerces-C++ runtime + + * "Type-less content" such as mixed content models, xsd:anyType/ + xsd:anySimpleType, and xsd:any/xsd:anyAttribute is supported by + exposing corresponding DOM nodes (see the keep_dom parsing flag). + Note that only a subset of XML Schema xsd:any functionality is + supported. The compiler will issue diagnostics for unsupported + cases. See examples/cxx/tree/mixed for a code sample. + + C++/Parser + + * Support for inheritance-by-restriction in complex types. + + * "Type-less content" such as mixed content models, xsd:anyType/ + xsd:anySimpleType, and xsd:any/xsd:anyAttribute is supported + by forwarding parsing events to a set of "unexpected" hooks. + Note that only a subset of XML Schema xsd:any functionality is + supported. The compiler will issue diagnostics for unsupported + cases. See examples/cxx/parser/mixed for a code sample. + +Version 1.4.0 + + * Number of improvements and bug fixes in the diagnostics code. + + * libxsd has been reorganized to provide a clean split of code with + regards to char/wchar_t use. It should be possible to use libxsd + and the xsd-generated code on platforms that lack wchar_t support, + such as mingw. + + C++/Tree + + * Work around for g++ bug# 23206. + + * Support for xsd:list. + + * Type/member name conflicts are auto-resolved. Such conflicts + occur when a type and an element or attribute withing this type + share the same name. + + * XML Schema extension, the 'refType' attribute, allows one to + specify referenced type for xsd:IDREF and xsd:IDREFS data types. + See examples/cxx/tree/library for details. + + * New option, --morph-anonymous, allows automatic morphing + of anonymous types to named ones. See the man pages for + details. + + * New option, --namespace-regex-trace, allows one to trace the + namespace mapping process. See the man pages for details. + + * Mapping for optional elements/attributes (cardinality 0..1) + has changed in a backwards-incompatible way. In the previous + version you would write: + + Bar& bar = ... + + if (bar.foo.present ()) // test + { + Foo& foo (bar.foo ()); // get + + bar.foo (Foo (...)); // set + + bar.foo.reset (); // reset + } + + Now you would write it like this: + + if (bar.foo ().present ()) // test + { + Foo& foo (bar.foo ().get ()); // get + + bar.foo (Foo (...)); // set + + bar.foo ().reset (); // reset + } + + Or using the pointer notation: + + if (bar.foo ()) // test + { + Foo& foo (*bar.foo ()); // get + + bar.foo (Foo (...)); // set + + bar.foo ().reset (); // reset + } + + C++/Parser + + * Support for xsd:list. + + * Type/member name conflicts are auto-resolved.
