| * Extension overhaul.Max Cai2014-01-101-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* | Add validation when parsing enum fields.Max Cai2014-01-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | Invalid values from the wire are silently ignored. Unlike full/lite, the invalid values are not stored into the unknown fields, because there's no way to get them out from Nano's unknown fields without a matching Extension. Edited README and slightly moved it towards a standalone section for Nano, independent of the Micro section. Change-Id: I2c1eb07f4d6d8f3aea242b8ddd95b9c966f3f177
* | Allow whitespace in nano codegen options.Max Cai2014-01-141-1/+5
|/ | | | | | So we don't need to keep all option in a single line in the .mk files. Change-Id: I786b879b334cac4cd13b32fabcb76efe53b4ac80
* Align with main: two ways of parsing repeated packable fields.Max Cai2013-11-181-0/+1
| | | | | | | | | | | | | | | 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
* Implement hashCode() and equals() behind a generator option.Brian Duff2013-10-251-4/+4
| | | | | | | | | | | | | | | | 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.

* Fix repeated field merging semantics.Max Cai2013-10-151-0/+1
| | | | | | | | | | The public doc states that repeated fields are simply concatenated and doesn't impose a different semantics for packed fields. This CL fixes this for packed fields and adds tests covering all cases. Also fixed a bit of missed null-repeated-field treatments. Change-Id: Ie35277bb1a9f0b8171dc9d07b6adf9b9d3308de2
* Add reftypes field generator option.Brian Duff2013-10-071-0/+6
| | | | | | | | This option generates fields as reference types, and serializes based on nullness. Change-Id: Ic32e0eebff59d14016cc9a19e15a9bb08ae0bba5 Signed-off-by: Brian Duff <bduff@google.com>
* Implement enum_style=java option.Max Cai2013-09-251-0/+8
| | | | | | | | | | This javanano_out command line option creates a container interface at the normal place where the enum constants would reside, per enum definition. The java_multiple_files flag would now affect the file- scope enums with the shells. If the flag is true then file-scope container interfaces are created in their own files. Change-Id: Id52258fcff8d3dee9db8f3d8022147a811bf3565
* Accessor style for optional fields.Max Cai2013-09-231-0/+6
| | | | | | | | | | | This CL implements the 'optional_field_style=accessors' option. All optional fields will now be 1 Java field and 1 bit in a shared bitfield behind get/set/has/clear accessor methods. The setter performs null check for reference types (Strings and byte[]s). Also decentralized the clear code generation. Change-Id: I60ac78329e352e76c2f8139fba1f292383080ad3
* Fix outer classname for javamicro/javanano.Max Cai2013-08-051-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - File class name is defined as the java_outer_classname option value or the file name ToCamelCase; never the single message's ClassName. - File-scope enums are translated to constants in the file class, regardless of java_multiple_files. - If java_multiple_files=true, and file's class name equals a message's class name, no error. This is done by detecting that the outer class is not needed and skipping the outer class codegen and clash checks. Note: there is a disparity between java[lite] and the previous java{micr|nan}o: when generating code for a single-message proto, the outer class is omitted by java{micr|nan}o if the file does not have java_outer_classname. This change makes java{micr|nan}o align with java[lite] codegen and create the outer class, but will print some info to warn of potential change of code. - Also fixed the "is_own_file" detection and made all parseX() methods static. Previously, all messages in a java_multiple_files=true file are (incorrectly) considered to be in their own files, including nested messages, causing them to become inner classes (instance- bound) and forcing the parseX() methods to lose the static modifier. - This change supersedes c/60164 and c/60086, which causes javanano to put enum values into enum shell classes if java_multiple_files=true. We now always use the parent class to host the enum values. A future change will add a command line option to provide more flexibility. - Elaborated in java/README.txt.

* Add an option to inspect "has" state upon parse.Ulas Kirazci2013-07-291-0/+8
| | | | | | If has is set, also always serialize. Change-Id: I2c8450f7ab9e837d722123dd1042991c0258ede3
* Per-file java_multiple_files flag.Max Cai2013-07-251-0/+2
| | | | | | | | | | | | | | | Imported source files may have different values for the 'java_multiple_files' option to the main source file's. Whether the fully qualified Java name of an entity should include the outer class name depends on the flag value in the file defining the referenced entity, not the main file. This CL loads the flag values from the main and all transitively imported files into the params, and generates the fully qualified Java names accordingly. If the generator option 'java_multiple_files' is set, its value overrides any in-file values in all source/imported files. This is because this generator option is typically used on either none or all source files. Change-Id: Id6a4a42426d68961dc669487d38f35530deb7d8e
* Nano support for extensions and unknown fields.Brian Duff2013-06-241-0/+6
| | | | | | | | | | | | | | | | | | | | You can use the processor option store_unknown_fields to switch this support on: aprotoc --javanano_out=store_unknown_fields=true:/tmp/out A separate option for extensions isn't required. Support for unknown fields must be turned on to allow storing and retrieving extensions, because they are just stored as unknown fields. If unknown fields are switched on, extension related code will be generated when a proto message includes an extension range, or an extension is encountered. By default, store_unknown_fields is false. No additional code is generated, and the generator will error out if protos contain extension ranges or extensions.

* Nano protobufs.Ulas Kirazci2013-04-011-0/+52
| | | | | | | | | | | | | | | | | | Like micro protobufs except: - No setter/getter/hazzer functions. - Has state is not available. Outputs all fields != their default. - CodedInputStream can only take byte[] (not InputStream). - Repeated fields are in arrays, not ArrayList or Vector. - Unset messages/groups are null, not "defaultInstance()". - Required fields are always serialized. To use: - Link libprotobuf-java-2.3.0-nano runtime. - Use LOCAL_PROTOC_OPTIMIZE_TYPE := nano Change-Id: I7429015b3c5f7f38b7be01eb2d4927f7a9999c80
* Changed speed optimization for strings.Wink Saville2010-06-071-1/+0
| | | | | | | | | | | Removed use of StringUtf8Micro and instead use an extra byte array instance variable directly in the class. This allows the list returned for repeated strings to be a String instead of a StringUtf8Micro making the class compatible with existing code. Removed PerfTimer.java which isn't used.
