| Avro Change Log |
| |
| Avro 1.2.0 (14 October 2009) |
| |
| INCOMPATIBLE CHANGES |
| |
| AVRO-115. Remove RPC's session notion to facilliate the use of |
| stateless transports like UDP and HTTP. Add a UDP transport. |
| (cutting) |
| |
| AVRO-120. Improved package and namespace handling, including: |
| |
| * Removed explicit package-name specification from specific and |
| reflect public APIs. Package names are now determined either |
| by namespace declarations or by a Java classes, as appropriate. |
| |
| * Changed the specific compiler to generate separate java files |
| per class, rather than nested classes. This permits generated |
| classes to be in packages declared in their schema namespaces. |
| |
| * Fix namespace defaulting. The default namespace is declared in |
| the outermost schema or protocol. Nested schemas can now |
| declare different namespaces than the default. |
| |
| * Names may now be specified with a dotted notation, e.g., |
| "foo.bar.Baz", to indicate the name "Baz" in namespace |
| "foo.bar". This permits one to refer to schemas in a namespace |
| other than the default. |
| |
| NEW FEATURES |
| |
| AVRO-121. Permit reflect and specific datum readers to read data |
| written with a different version of the schema than is current. |

| without running checkstyle or javadoc. (Thiruvalluvan M. G. via |

| the command line that depend on ivy, ivy does not fail. (phunt |
| via cutting) |
| |

| Avro 1.1.0 (8 September 2009) |
| |
| INCOMPATIBLE CHANGES |
| |
| AVRO-110. GenericData and ReflectData have been converted to use a |
| singleton pattern. Calls to static methods on these classes must |
| be replaced with calls on the singleton instance. (cutting) |
| |
| AVRO-41. GenericArray's constructor now requires a Schema, so that |
| it may implement Comparable consistently with AVRO-108. (cutting) |
| |
| AVRO-41. Several GenericDatumWriter methods (instanceOf(), |
| isRecord(), etc.) have been moved to GenericData, where they can |
| better be shared with comparators. Applications which subclassed |
| GenericDatumWriter overriding these methods must now instead |
| subclass GenericData and pass their subclass to |
| GenericDatumWriter. (cutting) |
| |
| AVRO-41. SpecificRecord's schema() method has been renamed |
| getSchema(), since it now implements the new GenericContainer |
| interface shared with GenericRecord. (cutting) |

| M. G. & cutting) |

| document. (cutting) |
| |
| AVRO-108. Add Java implementation of binary comparator. |
| (cutting) |
| |
| AVRO-41. Java generic and specific data instances now implement |
| Comparable. The implementation is consistent with the binary |
| comparator added in AVRO-108. (cutting) |
| |
| AVRO-109. Add Java support for controlling sort order via schema |
| annotations. Record fields now support an "order" attribute whose |
| possible values are "increasing" (the default), "decreasing", and |
| "ignore". (cutting) |
| |
| AVRO-111. Document sort ordering in the specification. (cutting) |
| |
| IMPROVEMENTS |
| |
| AVRO-71. C++: make deserializer more generic. (Scott Banachowski |
| via cutting) |

| order and to ignore extra attributes. (Scott Banachowski via cutting) |

| correctly in Java. (Thiruvalluvan M. G. via cutting) |
| |
| AVRO-87. Fix broken links in javadoc introduced by AVRO-82. Also |
| change test-java build target to fail on javadoc warnings. |
| (Thiruvalluvan M. G. and cutting) |
| |
| AVRO-90. Fix Java's JSON codec to correctly encode unions. (cutting) |
| |
| AVRO-95. Fix writing of Java reflect-based unions. Also extend |
| DataFileWriter to permit adding branches to a union schema while |
| writing. |
| |
| AVRO-88. Fix Java's BlockingBinaryEncoder to correctly override |
| writeEnum(). (Ravi Gummadi via cutting) |
| |

| throw ClassCastException when a fixed schema is compared to |
| non-fixed. (cutting) |
| |
| AVRO-112. Turn off C++ debug output. (Scott Banachowski via cutting) |
| |
| AVRO-114. Fix "cdoc" Ant target to correctly run doxygen. |
| (Matt Massie via cutting) |
