CHANGES.txt - platform/external/protobuf-javalite - Gitiles

 ????-??-?? version 2.0.4:

   General
   * Repeated fields of primitive types (types other that string, group, and
     nested messages) may now use the option [packed = true] to get a more
     efficient encoding.  In the new encoding, the entire list is written
     as a single byte blob using the "length-delimited" wire type.  Within
     this blob, the individual values are encoded the same way they would
     be normally except without a tag before each value (thus, they are
     tightly "packed").
   * For each field, the generated code contains an integer constant assigned
     to the field number.  For example, the .proto file:
       message Foo { optional int bar_baz = 123; }
     would generate the following constants, all with the integer value 123:
       C++:     Foo::kBarBazFieldNumber
       Java:    Foo.BAR_BAZ_FIELD_NUMBER
       Python:  Foo.BAR_BAZ_FIELD_NUMBER
     Constants are also generated for extensions, with the same naming scheme.
     These constants may be used as switch cases.

   protoc
   * --error_format=msvs option causes errors to be printed in Visual Studio
     format, which should allow them to be clicked on in the build log to go
     directly to the error location.

   C++
   * UnknownFieldSet now supports STL-like iteration.
   * Message interface has method ParseFromBoundedZeroCopyStream() which parses
     a limited number of bytes from an input stream rather than parsing until
     EOF.
   * GzipInputStream and GzipOutputStream support reading/writing gzip- or
     zlib-compressed streams if zlib is available.
     (google/protobuf/io/gzip_stream.h)
   * Generated constructors explicitly initialize all fields (to avoid warnings
     with certain compiler settings).

   Java
   * Fixed bug where Message.mergeFrom(Message) failed to merge extensions.
   * Message interface has new method toBuilder() which is equivalent to
     newBuilderForType().mergeFrom(this).
   * All enums now implement the ProtocolMessageEnum interface.
   * Setting a field to null now throws NullPointerException.
   * Fixed tendency for TextFormat's parsing to overflow the stack when
     parsing large string values.  The underlying problem is with Java's
     regex implementation (which unfortunately uses recursive backtracking
     rather than building an NFA).  Worked around by making use of possesive
     quantifiers.

   Python
   * Added slicing support for repeated scalar fields. Added slice retrieval and
     removal of repeated composite fields.
   * Updated RPC interfaces to allow for blocking operation.  A client may
     now pass None for a callback when making an RPC, in which case the
     call will block until the response is received, and the response
     object will be returned directly to the caller.  This interface change
     cannot be used in practice until RPC implementations are updated to
     implement it.

 2008-11-25 version 2.0.3:

   protoc
   * Enum values may now have custom options, using syntax similar to field
     options.
   * Fixed bug where .proto files which use custom options but don't actually
     define them (i.e. they import another .proto file defining the options)
     had to explicitly import descriptor.proto.
   * Adjacent string literals in .proto files will now be concatenated, like in
     C.
   * If an input file is a Windows absolute path (e.g. "C:\foo\bar.proto") and
     the import path only contains "." (or contains "." but does not contain
     the file), protoc incorrectly thought that the file was under ".", because
     it thought that the path was relative (since it didn't start with a slash).
     This has been fixed.

   C++
   * Generated message classes now have a Swap() method which efficiently swaps
     the contents of two objects.
   * All message classes now have a SpaceUsed() method which returns an estimate
     of the number of bytes of allocated memory currently owned by the object.
     This is particularly useful when you are reusing a single message object
     to improve performance but want to make sure it doesn't bloat up too large.
   * New method Message::SerializeAsString() returns a string containing the
     serialized data.  May be more convenient than calling
     SerializeToString(string*).
   * In debug mode, log error messages when string-type fields are found to
     contain bytes that are not valid UTF-8.
   * Fixed bug where a message with multiple extension ranges couldn't parse
     extensions.
   * Fixed bug where MergeFrom(const Message&) didn't do anything if invoked on
     a message that contained no fields (but possibly contained extensions).
   * Fixed ShortDebugString() to not be O(n^2).  Durr.
   * Fixed crash in TextFormat parsing if the first token in the input caused a
     tokenization error.
   * Fixed obscure bugs in zero_copy_stream_impl.cc.
   * Added support for HP C++ on Tru64.
   * Only build tests on "make check", not "make".
   * Fixed alignment issue that caused crashes when using DynamicMessage on
     64-bit Sparc machines.
   * Simplify template usage to work with MSVC 2003.
   * Work around GCC 4.3.x x86_64 compiler bug that caused crashes on startup.
     (This affected Fedora 9 in particular.)
   * Now works on "Solaris 10 using recent Sun Studio".

   Java
   * New overload of mergeFrom() which parses a slice of a byte array instead
     of the whole thing.
   * New method ByteString.asReadOnlyByteBuffer() does what it sounds like.
   * Improved performance of isInitialized() when optimizing for code size.

   Python
   * Corrected ListFields() signature in Message base class to match what
     subclasses actually implement.
   * Some minor refactoring.
   * Don't pass self as first argument to superclass constructor (no longer
     allowed in Python 2.6).

 2008-09-29 version 2.0.2:

   General
   * License changed from Apache 2.0 to New BSD.
   * It is now possible to define custom "options", which are basically
     annotations which may be placed on definitions in a .proto file.
     For example, you might define a field option called "foo" like so:
       import "google/protobuf/descriptor.proto"
       extend google.protobuf.FieldOptions {
         optional string foo = 12345;
       }
     Then you annotate a field using the "foo" option:
       message MyMessage {
         optional int32 some_field = 1 [(foo) = "bar"]
       }
     The value of this option is then visible via the message's
     Descriptor:
       const FieldDescriptor* field =
         MyMessage::descriptor()->FindFieldByName("some_field");
       assert(field->options().GetExtension(foo) == "bar");
     This feature has been implemented and tested in C++ and Java.
     Other languages may or may not need to do extra work to support
     custom options, depending on how they construct descriptors.

   C++
   * Fixed some GCC warnings that only occur when using -pedantic.
   * Improved static initialization code, making ordering more
     predictable among other things.
   * TextFormat will no longer accept messages which contain multiple
     instances of a singular field.  Previously, the latter instance
     would overwrite the former.
   * Now works on systems that don't have hash_map.

   Java
   * Print @Override annotation in generated code where appropriate.

   Python
   * Strings now use the "unicode" type rather than the "str" type.
     String fields may still be assigned ASCII "str" values; they will
     automatically be converted.
   * Adding a property to an object representing a repeated field now
     raises an exception.  For example:
       # No longer works (and never should have).
       message.some_repeated_field.foo = 1

   Windows
   * We now build static libraries rather than DLLs by default on MSVC.
     See vsprojects/readme.txt for more information.

 2008-08-15 version 2.0.1:

   protoc
   * New flags --encode and --decode can be used to convert between protobuf text
     format and binary format from the command-line.
   * New flag --descriptor_set_out can be used to write FileDescriptorProtos for
     all parsed files directly into a single output file.  This is particularly
     useful if you wish to parse .proto files from programs written in languages
     other than C++: just run protoc as a background process and have it output
     a FileDescriptorList, then parse that natively.
   * Improved error message when an enum value's name conflicts with another
     symbol defined in the enum type's scope, e.g. if two enum types declared
     in the same scope have values with the same name.  This is disallowed for
     compatibility with C++, but this wasn't clear from the error.
   * Fixed absolute output paths on Windows.
   * Allow trailing slashes in --proto_path mappings.

   C++
   * Reflection objects are now per-class rather than per-instance.  To make this
     possible, the Reflection interface had to be changed such that all methods
     take the Message instance as a parameter.  This change improves performance
     significantly in memory-bandwidth-limited use cases, since it makes the
     message objects smaller.  Note that source-incompatible interface changes
     like this will not be made again after the library leaves beta.
   * Heuristically detect sub-messages when printing unknown fields.
   * Fix static initialization ordering bug that caused crashes at startup when
     compiling on Mac with static linking.
   * Fixed TokenizerTest when compiling with -DNDEBUG on Linux.
   * Fixed incorrect definition of kint32min.
   * Fix bytes type setter to work with byte sequences with embedded NULLs.
   * Other irrelevant tweaks.

   Java
   * Fixed UnknownFieldSet's parsing of varints larger than 32 bits.
   * Fixed TextFormat's parsing of "inf" and "nan".
   * Fixed TextFormat's parsing of comments.
   * Added info to Java POM that will be required when we upload the
     package to a Maven repo.

   Python
   * MergeFrom(message) and CopyFrom(message) are now implemented.
   * SerializeToString() raises an exception if the message is missing required
     fields.
   * Code organization improvements.
   * Fixed doc comments for RpcController and RpcChannel, which had somehow been
     swapped.
   * Fixed text_format_test on Windows where floating-point exponents sometimes
     contain extra zeros.
   * Fix Python service CallMethod() implementation.

   Other
   * Improved readmes.
   * VIM syntax highlighting improvements.
