* Inline unknownFieldData{Equals,HashCode} to generated code.Brian Duff2015-04-061-2/+8
| | | | | | | | | | 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.

|\ | | | | | | | | | | | | Parcelable message." * commit 'eff5d5b33b3ef8b655ce43e9f64578a8c8e4e482': Generate a CREATOR for each Parcelable message.
| * Generate a CREATOR for each Parcelable message.Jeff Davidson2015-04-031-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Expose generate_clear as an option.Brian Duff2015-02-211-0/+2
|/ | | | | | | | | | | | | | | | | | I wasn't able to get the clear() method to inline into the constructor when optimizations are on in proguard. As a result, every message has an extra superfluous kept method assuming the app never uses clear() directly. There are a couple of instances where setting this option false is necessary in order to get code dexing successfully without hitting the method limit, e.g. https://goto.google.com/tltzq In this example, I tried turning on the method/inlining/unique and method/inlining/short optimizations before resorting to adding the generate_clear option, but the method count did not decrease. The clear() methods were contributing over a thousand extra methods. Change-Id: If6a9651d6a59cdf70b1040d8248779710ac73105

* Upgrade protobuf library to v2.6.1.Jeff Davidson2015-01-20229-265/+502
| | | | | | | | | | | | | | | | 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".

| * When no clear() is generated, still initialize fields.Brian Duff2015-01-092-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://android-review.googlesource.com/#/c/67890/ removed field initialization from the ctor, making it just call clear() instead. When I added the generate_clear option back (as part of the reftypes compat mode) in https://android-review.googlesource.com/#/c/109530/, I forgot to ensure that what clear() used to do was inlined in the constructor. This change fixes NPEs that are happening for users of reftypes_compat_mode who rely on unset repeated fields being empty arrays rather than null. Change-Id: Idb58746c60f4a4054b7ebb5c3b0e76b16ff88184

* Fix bug with large extension field numbers.Brian Duff2014-10-032-1/+4
| | | | | | | | | | | | | | | | | | | Previously, extensions with field numbers greater than 268435455 would result in a compile time error in generated code that looks something like this: Foo.java:3178: error: integer number too large: 3346754610 3346754610); This is because we were trying to represent the tag number (an unsigned int) using a java int constant, but java int constants are signed, and can't exceed Integer.MAX_VALUE. Fixed by declaring it as a long instead, and casting it down to an int in the implementation. This is safe, because the tag value always fits in 32 bis.

* Support generation of Parcelable nano messages.Jeff Davidson2014-04-253-2/+20
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Invalid values from the wire are silently ignored.

* | Correctness: floating point equality using bits instead of ==.Max Cai2014-01-103-40/+62
| | | | | | | | | | | | | | | | | | | | | | 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 Cai2013-12-1010-76/+219
| | | | | | | | | | | | | | | | | | | 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.

* Nano: don't generate accessor methods for nested methodsAndrew Flynn2013-12-093-119/+6
| | | | | | | | | For nested message objects, don't generate accessor methods because they have a default value that is not a valid value (null), so there is no reason to have get/set/has/clear methods for them. Clients and protos (while serializing) can check against the invalid value to see if it's been set. Change-Id: Ic63400889581271b8cbcd9c45c84519d4921fd4b
* Align with main: two ways of parsing repeated packable fields.Max Cai2013-11-188-106/+252
| | | | | | | | | | | | | | | It is a requirement for parsing code to handle packed and unpacked forms on the wire for repeated packable fields. This change aligns the javanano's behavior with the java's. Bonus: optimize array length calculation when parsing repeated fixed-size-element-type fields. Bonus 2: lose "xMemoizedSerializedSize" for repeated enum fields, and make the serialized size calculation match that for repeated int32 fields. Change-Id: I8a06103d9290234adb46b0971b5ed155544fe86a

| | | | | | | | | | | | | | | | | | | Strip the null elements out before serializing the array. This is helpful in the cases where the user wants to construct an array of an inexact size for serialization. For example: User constructs array of size 5 because they anticipate adding more than 1 element before serialization. Only 3 get added, so the array looks like [Obj, Obj, Obj, null, null]. This would curently crash without this CL. All repeated fields of ref-type elements can contain null elements: repeated strings, repeated bytes, and repeated messages/groups.

* Implement hashCode() and equals() behind a generator option.Brian Duff2013-10-2513-57/+456
| | | | | | | | | | | | | | | | The option is only called 'generate_equals' because: - equals() is the main thing; hashCode() is there only to complement equals(); - it's shorter; - toString() should not be included in this option because it's more for debugging and it's more likely to stop ProGuard from working well. Also shortened the "has bit" expression; was ((bitField & mask) == mask), now ((bitField & mask) != 0). Both the Java code and the bytecode are slightly shorter.

| | | | | | | | | | | | Also pre-inlines set() and has() in serialization code. This could theoretically help ProGuard: the message class size is usually large, and because of this only, it may refuse to inline an accessor into the serialization code, and as a result keeps the accessor intact. Chances are, after pre-inlining all accessor calls within the message class, those accessors become unused or single-use, so there are more reasons for ProGuard to inline and then remove them.
