Escape characters don't count for string literal size, no need to pre-generate escape string.
Added unit test to touch enormous cpp generated descriptor.
Updated makefile to include enormous_descriptor.proto
Fixed language compatibility error.
This is effectively reimplementing List<T>, but with a few advantages:
- We know that an empty repeated field is common, so don't allocate an array until we need to
- With direct access to the array, we can easily convert enum values to int without boxing
- We can relax the restrictions over what happens if the repeated field is modified while iterating, avoiding so much checking
This is somewhat risky, in that reimplementing a building block like this is *always* risky, but hey...
(The performance benefits are significant...)
This mirrors commit 7c86bbbc7a in the pull request to
the main protobuf project, but also reduces the size of the buffer created. (There's no point in
creating a 1024-byte buffer if we're only skipping 5 bytes...)
Remove ICodedInputStream and ICodedOutputStream, and rewrite CodedInputStream and CodedOutputStream to be specific to the binary format. If we want to support text-based formats, that can be a whole different serialization mechanism.
This makes repeated fields really awkward at the moment - but when we reimplement RepeatedField<T> to be backed by an array, we can cast the array directly...
Cache a reference to Encoding.UTF8 - the property access is (rather surprisingly) significant.
Additionally, when we detect that the string is all ASCII (due to the computed length in bytes being the length in characters), we can perform the encoding very efficiently ourselves.
Refactored the threadlocal logic for Android and IOS into logic in
platform_macro.h which computes a GOOGLE_PROTOBUF_NO_THREADLOCAL
define which is then used elsewhere. This allows new platforms
without THREADLOCAL to be easily defined.
- 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.
When compiling a protobuf with gcc 4.1.2 for powerpc, I ran into
another of the following warning message:
INFO: From Compiling my_proto.pb.cc powerpc-603e-linux-gcc:
bazel-out/local_linux-dbg/genfiles/my_proto.pb.cc: In member
function `virtual void MyProto::Clear()':
bazel-out/local_linux-dbg/genfiles/my_proto.pb.cc:223: warning: this
decimal constant is unsigned only in ISO C90
The line in the proto file that was triggering it was:
if (_has_bits_[24 / 32] & 4278190080) {
ZR_(field1_, field2_);
}
_has_bits_ is a uint32. The constant mask should therefore be
unsigned. This change updates the constant to be generated as
unsigned.
