Log Message:
Updated protobuf to 3.3.0.
2017-04-05 version 3.3.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)
Planned Future Changes
* There are some changes that are not included in this release but are
planned for the near future:
- Preserve unknown fields in proto3: please read this doc:
\
https://docs.google.com/document/d/1KMRX-G91Aa-Y2FkEaHeeviLRRNblgIahbsk4wA14gRk/view
for the timeline and follow up this github issue:
https://github.com/google/protobuf/issues/272
for discussion.
- Make C++ implementation C++11 only: we plan to require C++11 to build
protobuf code starting from 3.4.0 or 3.5.0 release. Please join this
github issue:
https://github.com/google/protobuf/issues/2780
to provide your feedback.
C++
* Fixed map fields serialization of DynamicMessage to correctly serialize
both key and value regardless of their presence.
* Parser now rejects field number 0 correctly.
* New API Message::SpaceUsedLong() thatâs equivalent to
Message::SpaceUsed() but returns the value in size_t.
* JSON support
- New flag always_print_enums_as_ints in JsonPrintOptions.
- New flag preserve_proto_field_names in JsonPrintOptions. It will instruct
the JSON printer to use the original field name declared in the .proto
file instead of converting them to lowerCamelCase when printing JSON.
- JsonPrintOptions.always_print_primtive_fields now works for oneof message
fields.
- Fixed a bug that doesnât allow different fields to set the same json_name
value.
- Fixed a performance bug that causes excessive memory copy when printing
large messages.
* Various performance optimizations.
Java
* Map field setters eagerly validate inputs and throw NullPointerExceptions
as appropriate.
* Added ByteBuffer overloads to the generated parsing methods and the Parser
interface.
* proto3 enum's getNumber() method now throws on UNRECOGNIZED values.
* Output of JsonFormat is now locale independent.
Python
* Added FindServiceByName() in the pure-Python DescriptorPool. This works only
for descriptors added with DescriptorPool.Add(). Generated descriptor_pool
does not support this yet.
* Added a descriptor_pool parameter for parsing Any in text_format.Parse().
* descriptor_pool.FindFileContainingSymbol() now is able to find nested
extensions.
* Extending empty [] to repeated field now sets parent message presence.
PHP
* Added file option php_class_prefix. The prefix will be prepended to all
generated classes defined in the file.
* When encoding, negative int32 values are sign-extended to int64.
* Repeated/Map field setter accepts a regular PHP array. Type checking is
done on the array elements.
* encode/decode are renamed to serializeToString/mergeFromString.
* Added mergeFrom, clear method on Message.
* Fixed a bug that oneof accessor didnât return the field name that is
actually set.
* C extension now works with php7.
* This is the first GA release of PHP. We guarantee that old generated code
can always work with new runtime and new generated code.
Objective-C
* Fixed help for GPBTimestamp for dates before the epoch that contain
fractional seconds.
* Added GPBMessageDropUnknownFieldsRecursively() to remove unknowns from a
message and any sub messages.
* Addressed a threading race in extension registration/lookup.
* Increased the max message parsing depth to 100 to match the other languages.
* Removed some use of dispatch_once in favor of atomic compare/set since it
needs to be heap based.
* Fixes for new Xcode 8.3 warnings.
C#
* Fixed MapField.Values.CopyTo, which would throw an exception unnecessarily
if provided exactly the right size of array to copy to.
* Fixed enum JSON formatting when multiple names mapped to the same numeric
value.
* Added JSON formatting option to format enums as integers.
* Modified RepeatedField<T> to implement IReadOnlyList<T>.
* Introduced the start of custom option handling; it's not as pleasant as it
might be, but the information is at least present. We expect to extend code
generation to improve this in the future.
* Introduced ByteString.FromStream and ByteString.FromStreamAsync to
efficiently create a ByteString from a stream.
* Added whole-message deprecation, which decorates the class with [Obsolete].
Ruby
* Fixed Message#to_h for messages with map fields.
* Fixed memcpy() in binary gems to work for old glibc, without breaking the
build for non-glibc libcâs like musl.
Javascript
* Added compatibility tests for version 3.0.0.
* Added conformance tests.
* Fixed serialization of extensions: we need to emit a value even if it is
falsy (like the number 0).
* Use closurebuilder.py in favor of calcdeps.py for compiling JavaScript.
