This reverts commit ca3674b7d5.
While there are savings, it ends up being to easy/common to run into issues with
AppStore validation since the selector usage now appears to be a possible match
for private apis vs. for selectors/properties in the generated code.
Adds an option to protoc `--objc_opt=elide_message_metadata` to remove all the property
metadata from message classes. This significantly reduces the codegen size of the clases.
The downside is that iterating through properties using objective c runtime calls will no
longer function. This is mitigated by the fact that most (all?) of the information that
folks are interested in can be extracted via the message descriptor.
We do this by defining our own classes using the `GPB_MESSAGE_SUBCLASS_IMPL` macro.
- Fix up -copyWithZone: to not leave the two registries sharing
some of the storage by using -addExtensions:.
- Improve -addExtensions: to clone the sub dict when there is
nothing to merge into.
- A ExtensionRegistry unittests.
- Update project schemes to not have extra things in perf scheme.
- Let Xcode 8 update settings on the projects/schemes.
- Migrate Swift tests to Swift 3 syntax.
- Update the build/test script:
- Require Xcode 8 (because of the Swift 3 requirement for tests)
- Update the devices to what Xcode 8 has (8.x simulator seem to fail even
though they can be downloaded in Xcode 8)
- Update the travis images to ones with Xcode 8.
- Let Xcode update the projects, schemes, and info.plists.
- Add workaround for shallow analyzer issues in current Xcode versions (deep analyze gets things correct).
- Tweak the Swift based tests to avoid warnings from Xcode 7's XCTest using optionals for autoenclosure results.
- No longer tag the ObjC iOS travis test as flaky, xctool seems to manage the simulator pretty well.
- 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.
