[protobuf] protobuf object-c GPBTypeString not found
hi~ I try to use protobuf in object c env, but it failed because the missing of the GPBTypeString, GPBTypeEnum ..., how to fix it ?

[protobuf] Re: protobuf object-c GPBTypeString not found
GPBDataTypeString rather than GPBTypeString can be found in GPBRuntimeTypes.h, so i think it's a bug ? 在 2015年12月3日星期四 UTC+8下午6:33:19，sam sun写道： > > hi~ I try to use protobuf in object c env, but it failed because the > missing of the GPBTypeString, GPBTypeEnum ..., how to fix it ?

[protobuf] JsonFormat parser use camel field name in proto3 beta1
I have a proto:
message Person {
string user_id;
}
and write a json:
{ "user_id" : "123" }
I try to use JsonFormat.Parser to parse the json, but it failed. I found
JsonFormat
will call fieldNameToCamelName. I'm really confused. If the parser in java
required camel fieldname, the parser in c++ required user_id or userId ?
I think it's better to let the field name reserved the same as defined in
proto or supply a optional to set whether convert the field name to camel.

Re: [protobuf] proto3 backward compatibility problem
Since the map type is important to me, i decided to use proto3, so i moved hashLong method from com.google.protobuf.Internal.hashLong/hashEnum/xx to GeneratedMessage in proto3 source code and solved the problem, however, to maintain a special version by myself is really a bad idea. I do think it's very import to keep full backward compatibility with code generated by proto2 since so many widely used opensource libs depends on protobuf as i have mentioned before, especially protobuf2.5.

Re: [protobuf] proto3 backward compatibility problem
I knew it, because yarn depends on proto2 but my lib depends on proto3. The reason is that proto3 runtime doesn't keep backward compatibility. The problem can be reproduced if set option java_generate_equals_and_hash = true with proto2. I hope msg with proto2 still work with proto3 jar since proto2 has been widely used in opensource system like yarn, hbase, etc. 在 2015年9月7日星期一 UTC+8下午2:31:04，Feng Xiao写道： > > On Sat, Sep 5, 2015 at 9:08 PM, sam sun <sun...@gmail.com > > wrote: > >> I use proto3 to log user event and then run a mapreduce to stat same >> metrics.

[protobuf] proto3 backward compatibility problem
I use proto3 to log user event and then run a mapreduce to stat same metrics. But it reports an error: Exception in thread "Thread-2" java.lang.NoSuchMethodError: org.apache.hadoop.yarn.proto.YarnProtos$LocalResourceProto.hashLong(J)I at org.apache.hadoop.yarn.proto.YarnProtos$LocalResourceProto.hashCode(YarnProtos.java:11555) at org.apache.hadoop.yarn.api.records.impl.pb.LocalResourcePBImpl.hashCode(LocalResourcePBImpl.java:62) at java.util.HashMap.hash(HashMap.java:338) at java.util.HashMap.put(HashMap.java:611) The problem is proto3 doesn't keep backward compatibility with proto2. hashLong is no longer exists in generated code with proto3. Now I faced a deed situation that neither proto2 nor proto3 can be loaded when i run a mapreduce job. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.

[protobuf] protobuf3 backward compatibility
I used proto3 to serialize events, and when i run mapreduce to read it , an error was raised: java.lang.NoSuchMethodError: org.apache.hadoop.yarn.proto.YarnProtos$LocalResourceProto.hashLong(J)I at org.apache.hadoop.yarn.proto.YarnProtos$LocalResourceProto.hashCode The problem is that i need proto3 to deserialize log, but yarn needs proto2. however proto3 doesn't keep backward compatibility ... Since i need some features only included in proto3(like map), It seems that i have no solution now. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
