Thomas Van Lenten	c8a440dfb6	Add more warnings to for the ObjC runtime build 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.	9 years ago
Thomas Van Lenten	79a23c435c	Shrink ObjC overhead (generated size and some runtime sizes) 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).	9 years ago
Thomas Van Lenten	d846b0b059	Beta quality drop of Objective C Support. - 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.	10 years ago
Thomas Van Lenten	1dcc329427	Objective C Second Alpha Drop - 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.	10 years ago
