* Throw OutOfSpaceException instead of IllegalArgumentException.Charles Munger2015-04-212-1/+28
| | | | | | | | | | | | | When a MessageNano containing a String is serialized into a buffer that is too small to contain it, and the buffer's boundary happens to be where the string field's length delimiting varint is serialized, and the string's length and 3*length have the same length when encoded as a varint, an IllegalArgumentException is thrown rather than an OutOfSpaceException.

* Generate a CREATOR for each Parcelable message.Jeff Davidson2015-04-033-36/+23
| | | | | | | | | | | | | | | This is less ideal from a dex count perspective because it requires a new variable for each message, and because most apps have proguard rules that will ensure that CREATOR classes are retained. However, it is required to be able to use nano protos inside of AIDL files, as the autogenerated AIDL code fails to compile otherwise. This is a substantial benefit as it allows for backwards-compatible parameters and return types in AIDL methods along the lines of safeparcel.

* Inline unknownFieldData{Equals,HashCode} to generated code.Brian Duff2015-03-202-33/+11
| | | | | | | | | | It turns out dex (apparently) was inlining these protected final methods from ExtendableMessageNano into every message class. Removing these methods from the base class and inlining their code reduces the method count by 2 methods / message when the store_unknown_fields option is on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous commit was actually between v2.6.0 and v2.6.1. This CL was created by generating a patch with: git format-patch edc5994525c79cd1919859a370837a6ff7c8e308..v2.6.1 and applying this patch to the tree. The patch was clean except for pom.xml, where the packaging type should have previously been changed from "jar" to "bundle".

Plan to upstream this fix per discussion with protobuf maintainers. Reran autogen.sh to update ./configure and associated scripts. Change-Id: I949d32fb5126f1c05e2a6ed48f6636a4a9b15a48

* | Keep pointers to extension values.Juan Silveira2014-07-148-256/+920
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of getExtension deserialises the field from bytes and returns a new object every time. This means that changes to those objects are reflected when the messages is serialised unless setExtension is called. It also means that every call to getExtension and setExtension is expensive. This change introduces a FieldData class that contains everything that's known about the field at the time. This can be all the tag/byte[] pairs associated with a given field or an Extension and a value object. This is so that two messages with a repeated extension can be compared even if the extension has been deserialised in one of them but not the other. This change also adds FieldArray class based on SparseArray from the Android compatibility library. This is used in ExtendableMessageNano to make lookup of FieldDatas by their field number faster. Implications: * calling getExtension multiple times deserialises the field only once and returns the same object. * calling setExtension doesn't cause the object to be serialised immediately, that only happens when the container message is serialised. * getExtension is no longer a read-only thread-safe operation. README.txt has been updated to relfect that. * comparison using equals and hashCode continues to work. Bug: 10863158 Change-Id: I81c7cb0c73cc0611a1f7c1eabf5eed259738e8bc

* Support generation of Parcelable nano messages.Jeff Davidson2014-04-256-1/+355
| | | | | | | | | | | | | | | | | | | | This CL adds the "parcelable_messages" option. When enabled, all generated message classes will conform to the Android Parcelable contract. This is achieved by introducing a new parent class for generated classes which implements the required functionality. Since the store_unknown_fields option also makes use of a superclass, ExtendableMessageNano, we have two versions of the new Parcelable superclass: one extending MessageNano, and one extending ExtendableMessageNano. These classes are otherwise identical. As these classes depend on Android framework jars, they are not included in the host .jar build of the nanoproto library. Finally, add a test suite for running tests of Android-specific functionality, as this cannot be done on a desktop JVM. Change-Id: Icc2a257f03317e947f7078dbb9857c3286857497

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of TypeLiteral<T>. It was introduced to read the component type of a List<T> at runtime. But we use arrays everywhere else, and we can always read the component type of an array type at runtime. - Properly read/write "minor" types (e.g. sint32, sfixed32). The old implementation could only read/write data as the "typical" types (one per Java type), e.g. java.lang.Integer -> int32, java.lang.Long -> int64. So if e.g. an extension specifies sfixed32 as the type, it would be read/written in the totally incompatible int32 format. - Properly serialize repeated packed fields. The old implementation doesn't do packed serialization. As an added bonus, and to be more aligned with the rest of protobuf nano / main, repeated packable extensions can deserialize both packed and non-packed data. - Split Extension class into a hierarchy so under typical usage a large chunk of code dealing with primitive type extensions can be removed by ProGuard.

| | | | | | | | | | | | | | | | | | | | | | Special values for float and double make it inaccurate to test the equality with ==. The main Java library uses the standard Object.equals() implementation for all fields, which for floating point fields means Float.equals() or Double.equals(). They define equality as bitwise equality, with all NaN representations normalized to the same bit sequence (and therefore equal to each other). This test checks that the nano implementation complies with Object.equals(), so NaN == NaN and +0.0 != -0.0. Change-Id: I97bb4a3687223d8a212c70cd736436b9dd80c1d7

* Avoid class initializers to help ProGuard.Max Cai2013-12-102-18/+29
| | | | | | | | | | | | | | | | | | | Class initializers prevent ProGuard from inlining any methods because it thinks the class initializer may have side effects. This is true for static methods, but instance methods can still be inlined, because to have an instance you will have touched the class and any class initializers would have run. But ProGuard only starts inlining instance methods of classes with class initializers from v4.11b6, and Android uses v4.4 now. This change tries to avoid the class initializers as much as possible, by delaying the initialization of the empty array and some fields' saved defaults until when they're needed. However, if the message hosts any extensions, they must be public static final and therefore introducing the class initializer. In that case we won't bother with lazy initialization.
