      Update the ObjC version checks to support a min and current version. · 1aa65000
      Thomas Van Lenten authored
      - Capture the version used to generated.
      - Check at compile time and runtime that generated code isn't from a newer
        version, also check that the min version required is also supported.
      - Keep the old constants/macros/functions to special case the last version
        that was working so those generated sources still work until we decide
        otherwise.

      Add ObjC helpers for Any WKT. · 337ec306
      Thomas Van Lenten authored
      - Capture the ObjC prefix used when generating the the file.
      - Track the containing type on descriptors.
      - Mark descriptors where the message class name got a suffix added to it.
      - Expose a fullName property on Descriptors.
      - Add helpers for packing/unpacking Any messages.
      - Bump the ObjC runtime version number. Since we added methods and invoke them
        in the generated code, ensure the code is running against a matching version.
        Otherwise, someone could compile against headers, but run with a framework
        that is older and get unknown selector failures.  This should trip clearer
        messaging.

      Add more warnings to for the ObjC runtime build · c8a440df
      Thomas Van Lenten authored
      Working on https://github.com/google/protobuf/issues/1599, specifically:
      - Turn on more warnings that the Xcode UI calls out with individual controls.
      - Manually add:
        -Wundef
        -Wswitch-enum
      - Manually add and then diable in the unittests because of XCTest's headers:
        -Wreserved-id-macro
        -Wdocumentation-unknown-command
      - Manually add -Wdirect-ivar-access, but disable it for the unittests and in
        the library code (via #pragmas to suppress it). This is done so proto users
        can enable the warning.

      Shrink ObjC overhead (generated size and some runtime sizes) · 79a23c43
      Thomas Van Lenten authored
      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).

      Objective C Second Alpha Drop · 1dcc3294
      Thomas Van Lenten authored
      - 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.
