* Better support for using the proto library from a framework.Thomas Van Lenten2016-06-131-36/+135
| | | | | | | | | | | | | | - Add generator constant for the default framework name. - Add generator api for making the CPP symbol from the name. - Add generator api to see if it is a bundled proto file. - Output a CPP conditional and two imports for the core library headers. - Add helper for generating the #import for file headers to deal with the framework imports. - Add a reference from the unittests to a WKT to use that to inspect how imports generate. - Update the podspec to define the CPP symbol and require pods 1.0 (or later). Fixes https://github.com/google/protobuf/issues/1457

* Shrink ObjC overhead (generated size and some runtime sizes)Thomas Van Lenten2016-03-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NOTE: This is a binary breaking change as structure sizes have changed size and/or order. - Drop capturing field options, no other options were captured and other mobile targeted languages don't try to capture this sort information (saved 8 bytes for every field defined (in static data and again in field descriptor instance size data). - No longer generate/compile in the messages/enums in descriptor.proto. If developers need it, they should generate it and compile it in. Reduced the overhead of the core library. - Compute the number of has_bits actually needs to avoid over reserving. - Let the boolean single fields store via a has_bit to avoid storage, makes the common cases of the instance size smaller. - Reorder some flags and down size the enums to contain the bits needed. - Reorder the items in the structures to manually ensure they are are packed better (especially when generating 64bit code - 8 bytes for every field, 16 bytes for every extension, instance sizes 8 bytes also). - Split off the structure initialization so when the default is zero, the generated static storage doesn't need to reserve the space. This is batched at the message level, so all the fields for the message have to have zero defaults to get the saves. By definition all proto3 syntax files fall into this case but it also saves space for the proto2 that use the standard defaults. (saves 8 bytes of static data for every field that had a zero default) - Don't track the enums defined by a message. Nothing in the runtime needs it and it was just generation and runtime overhead. (saves 8 bytes per enum) - Ensure EnumDescriptors are started up threadsafe in all cases. - Split some of the Descriptor initialization into multiple methods so the generated code isn't padded with lots of zero/nil args. - Change how oneof info is feed to the runtime enabling us to generate less static data (8 bytes saved per oneof for 64bit). - Change how enum value informat is capture to pack the data and only decode it if it ends up being needed. Avoids padding issues causing bloat of 64bit, and removes the needs for extra pointers in addition to the data (just the data and one pointer now).
* HeaderDoc support in the library and generated sourcesThomas Van Lenten2016-03-071-6/+8
| | | | | | | - Convert most of the core library headers over to HeaderDoc format. - Switch the generated comments over to HeaderDoc. - Create GPBCodedOutputStream_PackagePrivate and move some things into there that should be more internal.
* Support ObjC Generic CollectionsThomas Van Lenten2016-02-181-4/+6
| | | | | | | - Extend GPB*ObjectDictionary to support generic syntax. - Update the generator to output generics so the enclosed type is exposed for compiler checks. - Use generics in a the public interfaces. - Update the generated sources that are checked in.
* Tweak the error message as the generate is in the core binary these days.Thomas Van Lenten2015-12-021-1/+1

* Add support for a file listing expected package to objc prefixes for validation.Thomas Van Lenten2015-08-141-3/+0
| | | | | | - Add a env var to pass a set of expected prefixes for validation. - Report warnings/errors based on the expected prefixes vs. the data in the files compiled. - Use some helpers from common directory.
* Remove unused .pb.h #includes.Bo Yang2015-08-061-1/+0

* Add nonnil markup to ObjC library.Thomas Van Lenten2015-06-161-7/+11
| | | | Add the clang annotations to the objc library and generated code to help with Swift bridging and compiler checks.
* Beta quality drop of Objective C Support.Thomas Van Lenten2015-06-081-167/+126
| | | | | | | | | | | | | | | - Add more to the ObjC dir readme. - Merge the ExtensionField and ExtensionDescriptor to reduce overhead. - Fix an initialization race. - Clean up the Xcode schemes. - Remove the class/enum filter. - Remove some forced inline that were bloating things without proof of performance wins. - Rename some internal types to avoid conflicts with the well know types protos. - Drop the use of ApplyFunctions to the compiler/optimizer can do what it wants. - Better document some possible future improvements. - Add missing support for parsing repeated primitive fields in packed or unpacked forms. - Improve -hash. - Add *Count for repeated and map<> fields to avoid auto create when checking for them being set.
* Objective C Second Alpha DropThomas Van Lenten2015-05-221-60/+76
| | | | | | | | | | - Style fixups in the code. - map<> serialization fixes and more tests. - Autocreation of map<> fields (to match repeated fields). - @@protoc_insertion_point(global_scope|imports). - Fixup proto2 syntax extension support. - Move all startup code to +initialize so it happen on class usage and not app startup. - Have generated headers use forward declarations and move imports into generated code, reduces what is need at compile time to speed up compiled and avoid pointless rippling of rebuilds.
* Getting the ObjC generator building on Windows.Thomas Van Lenten2015-05-191-3/+4
| | | | | | | | | Remove the ClassList support (maybe bring it back in the future). Trim the includes to hopefully get a working Window build. Add some more returns after switches for compilers that warn even when all values of the enum are handled. Use ghtonl instead of htonl. Change the use of [u]int(8,32)_t within the ObjC generator code to [u]int(8,32) to match the rest of the compiler. Add objective-c generator files to Visual Studio project.
* Alpha 1 drop of Google's Objective C plugin and runtime support for protobufs.Thomas Van Lenten2015-05-061-0/+392
