Thomas Van Lenten	cf016a42e6	Work around strange error with atomic and swift under Xcode 8.3.3. Haven't been able to make a repo case, but this should "fix" the problem by avoid it completely. - Move readOnlySemaphore_ into the .m file so it isn't exposed in any header. - Move GPBGetObjectIvarWithField() also to go with the new limited visibility on the readOnlySemaphore_.	7 years ago
Thomas Van Lenten	3e1587fd4b	Add an explicit import of stdatomic.h. The generated code for enums needs atomics support, so generate the import instead of relying on it via transitive imports. This will make future changes to this likely likely to break generated code and runtime support are mixed. Followup to https://github.com/google/protobuf/pull/4184.	7 years ago
Thomas Van Lenten	6fd2ae7e45	Bring back import of OSAtomic. Followup to https://github.com/google/protobuf/pull/4184, keep the import to not break any existing generated code that isn't regenerated when they update to the newer protobuf code.	7 years ago

Thomas Van Lenten	130c166697	Remove the use of dispatch_once that is heap backed. Apple recently updated the docs on dispatch_once to point out that the storage for the dispatch_once_t must be static or global, but not something that was ever used before as the implementation doesn't use a memory barrier. So we drop the use and create the semaphore when needed and use an atomic swap deal with any threading races.	8 years ago

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	bd41a39f69	Only create the readonlySemaphore on demand. This will lower the amount of dispatch_semaphores created per Message when the full object tree isn't walked in a way that would require them to be created. Uses a dispatch_once_t for one time init of the dispatch_semaphore.	9 years ago
Thomas Van Lenten	d6590d6534	Drop all use of OSSpinLock Apple engineers have pointed out that OSSpinLocks are vulnerable to live locking on iOS in cases of priority inversion: . http://mjtsai.com/blog/2015/12/16/osspinlock-is-unsafe/ . https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20151214/000372.html - Use a dispatch_semaphore_t within the extension registry. - Use a dispatch_semaphore_t for protecting autocreation within messages. - Drop the custom/internal GPBString class since we don't have really good numbers to judge the locking replacements and it isn't required. We can always bring it back with real data in the future.	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
Thomas Van Lenten	30650d81d9	Alpha 1 drop of Google's Objective C plugin and runtime support for protobufs.	10 years ago
