I've heard this a couple of times before, that the type server stuff was
abandoned. Could the docs be updated to reflect this? They still indicate
that type definitions will be downloadable from servers via the type URL.

Re: [protobuf] How to generate google.protobuf.Type object from a file

2017-10-20 Thread Josh Humphries 
FWIW, I've implemented this logic in Go in a library called protoreflect,
with the intention that it could be used for the type server functionality,
as documented.

Take a look at the methods MessageAsPType and EnumAsPType in MessageRegistry:

Re: [protobuf] Can I represent the following JSON code in a protobuf?

2017-10-20 Thread 'Adam Cozzette' via Protocol Buffers 
Something like this should work (I just guessed at the type of the 1, 2,
and 3 fields since it's not clear from the example):

message InnerMessage {
  repeated int32 i1 = 1 [json_name = "1"];
  repeated int32 i2 = 2 [json_name = "2"];
  repeated int32 i3 = 3 [json_name = "3"];
}

message OuterMessage {
  repeated InnerMessage some_message = 1;
}

[protobuf] Equivalent of protoc --decode_raw via jvm library

2017-10-20 Thread Jeff White 
Is there anything that can generate the equivalent of 'protoc --decode_raw' 
in any of the jvm libraries?

Is it not a common use case to dump human-readable representation of the 
binary format in cases it cannot be parsed at runtime, for troubleshooting 
purposes?

Re: [protobuf] Error in the Java Classes for Protocol Buffer 3.4.1

2017-10-20 Thread Nasim Hasan 
Hello Adam,
 Thanks for replying to my mail. I think that, I have
found out the solution. Your Protocol Buffer's Version and Protocol
Buffer's Compiler (protoc) Version needs to be same. So, I have
followed that criteria and found out that everything is working fine
now...!!

Best Regards,
Nasim Hasan

Re: [protobuf] Protobuf Compile problems on the aix environment

2017-10-20 Thread 'Adam Cozzette' via Protocol Buffers 
We don't test on AIX because we don't have access to an AIX environment,
but I'm guessing that with a bit of effort you could get the code to
compile. If you can get it working, feel free to send us a pull request
with the necessary fixes.
