Avro 1.5.0 (10 March 2011)
INCOMPATIBLE CHANGES
AVRO-751. C: Each avro_datum_t instance now contains a reference to
the schema that the datum is an instance of. As a result, the
signatures of several of the functions that operate on avro_datum_t
instances have changed.
AVRO-647. Java: Break avro.jar up into multiple parts: avro.jar,
avro-compiler.jar, avro-ipc.jar, avro-mapred.jar, avro-tools.jar,
and avro-maven-plugin.jar.
Summary of artifacts:
* avro.jar
Contains 'core' avro features: schemas, data files,
specific, generic, and reflect APIs.
Dependencies: slf4j, Paranamer, Jackson.
* avro-ipc.jar
Contains Trancievers, Requestors, and Responders.
Dependencies: avro.jar, Jetty, Netty, and Velocity
* avro-compiler.jar
Contains SpecificCompiler, IDL compiler and Ant tasks.
Dependencies: avro.jar, commmons-lang, and Velocity.
* avro-maven-plugin.jar
A Maven plugin for Avro's compiler.
Dependencies: avro-compiler.jar
* avro-mapred.jar
API for Hadoop MapReduce with Avro data.
Dependencies: avro-ipc.jar, hadoop-core, and jopt-simple.
* avro-tools.jar
Avro command-line tools stand-alone jar.
Dependencies are contained within the jar.
Dependencies: all of the above.
(scottcarey)
AVRO-737. Java: Improve correlation between packages and modules.
Each module introduced by AVRO-647 now exclusively provides
different java packages. This required moving several classes
around into new packages and will therefore require users to
change their package imports when upgrading to Avro 1.5.0.
Summary of changes:
* AvroRemoteException has moved to org.apache.avro
* ByteBufferInputStream and ByteBufferInputStream have moved
to org.apache.avro.util
* InduceSchemaTool has moved to org.apache.avro.tools
* SpecificCompiler, SchemaTask, and ProtocolTask have moved
to org.apache.avro.compiler.specific
* The Idl compiler has moved to org.apache.avro.compiler.idl
* ReflectRequestor and ReflectResponder have moved to
org.apache.avro.ipc.reflect
* GenericRequestor and GenericResponder have moved to
org.apache.avro.ipc.generic
* SpecificRequestor and SpecificResponder have moved to
org.apache.avro.ipc.specific
(scottcarey)
AVRO-753. Java: Improve BinaryEncoder Performance.
The Encoder API has several resulting changes:
* Construction and configuration is handled by EncoderFactory. All
Constructors are hidden, and Encoder.init(OutputStream) is removed.
* Some Encoders previously did not buffer output. Users must call
Encoder.flush() to ensure output is written unless the EncoderFactory
method used to construct an instance explicitly states that the Encoder
does not buffer output.
(scottcarey)
AVRO-769. Java: Align Decoder/Encoder APIs for consistency and long term
stability. Avro's Decoder and Encoder APIs are aligned and now consist of
only read and write operations. EncoderFactory and DecoderFactory handle
all construction and common configuration. Some specialized implementations
have separate configuration APIs.
(scottcarey)
AVRO-670. Allow DataFileWriteTool to accept schema files as input with new
--schema-file and --schema command-line flags. (Ron Bodkin via philz)
AVRO-671. Java: Check that type and field names conform to

(Douglas Creager via brucem)
AVRO-656. Java: Add required Schema parameter to GenericData.Fixed
and GenericData.EnumSymbol constructors. Also fix union dispatch
to conform to specification, using full schema name for records,
enums and fixed.
NEW FEATURES
AVRO-762. C: New and improved schema resolution API. The new API
correctly handles all of the schema resolution rules listed in the
spec. It performs resolution against two schemas separately from
reading in any data, so that we don't have to re-resolve for each
data record. Please see the avro/consumer.h header file for
details. (dcreager)
AVRO-463. C: Error message API. The new avro_strerror() function
can be used to get a textual description of the error codes returned
by the other C API functions. In particular, this includes any JSON
parse errors that occur while trying to load a schema. (dcreager)
AVRO-684. Java: Add command-line "recodec" tool to change file
