[protobuf] Compiling protocol buffers on QNX 6.4
Hi, I have been trying to get protobuf to compile for a QNX6.4 system (already got it working fine on Linux). At first it had trouble finding libstdc++ in the auto-generated path but once I fixed it to take the library that ships with QNX6.4 there are still unresolved symbols related to that library. Has protobuf been successfully used on QNX? Any idea what I could be missing? Thanks, Vineet -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

[protobuf] Package Mandatory ?
Hello, When I include several couples of .h/.cc in my project, I got the following errors during the compilation: error C2086: 'google::protobuf::ProtobufOnceType `anonymous- namespace'::protobuf_AssignDescriptors_once_' : redefinition see declaration of '`anonymous- namespace'::protobuf_AssignDescriptors_once_' error C2084: function 'void `anonymous- namespace'::protobuf_AssignDescriptorsOnce(void)' already has a body see previous definition of 'protobuf_AssignDescriptorsOnce' error C2084: function 'void `anonymous- namespace'::protobuf_RegisterTypes(const std::string )' already has a body see previous definition of 'protobuf_RegisterTypes' Basically, it's telling me these functions are declared in all couples of .h/.cc. Using a different package for each couple of .h/.cc corrects the problem, but I don't want to do so. Without using any package, can someone explain me how to solve this error ?

[protobuf] Re: I am new in Protocol Buffers
When I first started using protobuf in my application, I relied solely on http://code.google.com/apis/protocolbuffers/docs/overview.html. It's a great resource of documentation and provides helpful examples. There's a cool plugin for Eclipse! You can get it at http://code.google.com/p/protobuf-dt/wiki/Installing. Protoc is the protocol buffer compiler. Once you've defined your protocol in the .proto file, you must compile it to a language of your choice (Python, C++, Java) so you can begin using it in your project.

[protobuf] proto buff crash
hi, we use proto buff for our c-s application. We find there seem to be no problems if server proto's optional, repeated field do not exist in client's proto, so our server and client use different proto defines, and it works well. But recently there happens some crash in client proto buff code when server send a lot of undefined complicate nested optional/repeated field to client. app.exe! std::basic_stringchar,std::char_traitschar,std::allocatorchar ::`scalar deleting destructor'() + 0x9 字节 C++ app.exe!google::protobuf::UnknownField::Delete() 行177 + 0x1f 字节 C++ app.exe!google::protobuf::UnknownFieldSet::ClearFallback() 行58 C++ app.exe!google::protobuf::UnknownFieldSet::~UnknownFieldSet() 行51 C+ + app.exe!MyProtoInner::~MyProtoInner() 行15119 + 0x4a 字节 C++ app.exe!MyProtoInner::`scalar deleting destructor'() + 0x8 字节 C++ app.exe! google::protobuf::internal::RepeatedPtrFieldBase::Destroygoogle::protobuf::RepeatedPtrFieldMyProtoInner::TypeHandler() 行622 + 0x11 字节 C++ app.exe!MyProto::~MyProto() 行16864 + 0x10 字节 C++ It seems happen in memory release procedure, and if we bring the 5 lines proto buff relative code to a gtest, it crash in same place steady.

[protobuf] Re: Support for xml, json, protobuf and Java Object Model retention
Hi, I'm trying a similar thing with trying to support Protobuffer for XINS (an open source web framework that also support different protocols). What I'd like to do is to parse a message and generate the output without the need to compile a .proto file. I'm looking at DynamicMessage but I can't find out how to parse a message or create a DynamicMessage. Please Google use the -use option of the javadoc to see how to create all the final classes that don't have constructors.

Currently, we use XML and JSON serialization provided by the Jersey framework. So, the only thing we need to do is set the correct mime- type. As far as my knowledge goes, the only way to be able to accomodate all three types would be to write MessageBodyReader/Writer that translate protobuf to XML and JSON and vice versa. This seems redundant to me since the Jersey framework already does XML and JSON serialization automatically. Is there a better way of achieving this? Also, we already have an object model defined in Java and would like to continue using the same model in the rest of the application. Is it possible to retain this model and not use the auto-generated entities for passing objects back and forth from the application?

[protobuf] How to read continuous stream of messages from TCP
Hello All; New to protobuf and did some limited search for my question. So my apology if this has already been talked about. I naively thought that ParseFromFileDescriptor/ParseFromIstream would block on an TCP socket and return when a valid message is received. Read some old posts from 2010 and realized it's not that easy due to mesages not being self-delimiting. And the suggestion from Jason Hsueh was as follows: One approach to writing multiple messages to the same stream is to use a length-delimited format: write the size of the message, then serialize the message itself. On the receiver side, you would set up a FileInputStream, and wrap a CodedInputStream around that. You can read the size of the messages from the stream and then use PushLimit and PopLimit to control how much data is read. My quesions are: 1. Is this still the way to do it? Seems quite cumbersome (to lazy me ;-). Is there a wrapper built in to do this? 2. If I understand Jason's suggestion riht, the length is really not part of the message, and the sender has to explcitly set it, instead of having protobuf encode it in. Which means a generic third party sender using my .proto file would not be sufficient. Plus how would they know the length before encoding the message proper? Filling it in after the fact would change the length again? or I am totally missing it. 3. A related quesiton is in general do I have to manage reading of the socket, or for that matter any istream, and spoon feed the protobuf parser until it says OK, that's a whole message?

[protobuf] Re: Issue 256 in protobuf: Error Converting Message to array of Bytes (When negative Enum) - Java
Updates: Labels: FixedIn-2.4.1 Comment #9 on issue 256 by jas...@google.com: Error Converting Message to array of Bytes (When negative Enum) - Java http://code.google.com/p/protobuf/issues/detail?id=256 2.4.1 should have contained this fix. Can you post a reproduction? If your serialization does not have a negative enum value, then please open a separate issue - the exception can occur generally when the ByteSize computation does not match the size of data written by the serializer. There is no message level interface, but you can just create the CodedOutputStream around your OutputStream directly: http://code.google.com/apis/protocolbuffers/docs/reference/java/com/google/protobuf/CodedOutputStream.html#newInstance(java.io.OutputStream, int) However, I think you should only be getting the OutOfSpaceException if you're using the byte[] version of the methods, in which case the data is written directly to the array. You need to make sure that the byte array you provide is sufficiently large. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

We are using writeDelimitedTo() and not write(), and unfortunately, while write() accepts a CodedOutputStream, writeDelimitedTo() does not, so I'm unable to figure out how to alter its buffer size. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

Comment #11 on issue 256 by jas...@google.com: Error Converting Message to array of Bytes (When negative Enum) - Java http://code.google.com/p/protobuf/issues/detail?id=256 The internal buffer for CodedOutputStream should just be a performance optimization; it's an internal buffer so that CodedOutputStream doesn't make a bunch of small writes to an OutputStream, which might be slow. I still don't see how it is possible to get an OutOfSpaceException if you are using writeDelimitedTo; an OutputStream must be provided for this API, but the OutOfSpaceException is only ever thrown if the CodedOutputStream has a null OutputStream: http://code.google.com/p/protobuf/source/browse/trunk/java/src/main/java/com/google/protobuf/CodedOutputStream.java#795 Can you start a new thread in the protobuf mailing list, with a small, self-contained reproduction of your problem? -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.
