Comment #4 on issue 351 by e...@chromium.org: Make protobuf_lite proto files not create any static initializers http://code.google.com/p/protobuf/issues/detail?id=351 It looks like on the Windows code path once.h still calls the ProtobufOnceType() ctor as a static initializer. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

[protobuf] Error: Byte size calculation and serialization were inconsistent
Hello, I have been using protobuf successfully for my project for a number of months now when I compile my project in gcc. Recently I went to compile my project in gcc with the -O optimization flag, but when running the project, I soon get an error when attempting to call SerializeAsString(): libprotobuf FATAL google/protobuf/message_lite.cc:65] CHECK failed: (bytes_produced_by_serialization) == (byte_size_before_serialization): Byte size calculation and serialization were inconsistent. This may indicate a bug in protocol buffers or it may be caused by concurrent modification of the message. terminate called after throwing an instance of 'google::protobuf::FatalException' what(): CHECK failed: (bytes_produced_by_serialization) == (byte_size_before_serialization): Byte size calculation and serialization were inconsistent. This may indicate a bug in protocol buffers or it may be caused by concurrent modification of the message.

[protobuf] Generate Descriptor from C/C++ Struct/Class
Hi,
I was wondering if there is a tool that can generate the Protocol
Buffers descriptor file from an existing C or C++ struct or class
declaration.
Also, I am looking for a tool that can generate C/C++ source code that
automatically populate data bi-directionally. For example, given the
C struct:
struct my_struct_t {
int a;
double b;
...
};
...
my_struct_t raw_data;
MyStruct pb_data = ...
// Generated code begins...
if (!pb_data.has_a()) raw_data.a = pb_data.a();
if (!pb_data.has_b()) raw_data.b = pb_data.b();
...
// End of generated code
Thanks.

[protobuf] Encoding question, datatypes packed repeated fields
I have some questions regarding packed fields, and storing/serializing data. What i want to do essentially, is to store 4MB of data to a file. The data i have comes as uint8_t (a byte) and i want to store these as efficiently as possible. I have been testing a variety of protobuf setups (four); repeated uint32_t datastruct = 1; repeated uint32_t datastruct = 1 [packed = true] with both variants assigned 1-to-1 and both variants bitshifted 4 values into a uint32_t. To my surprise the stored files are much larger than the original data. The best result i could achieve was 5.2MB for the 4MB data, which really isnt that good. Have i misunderstood something vital here? I do realize that protobuf adds information to the packets, but 25% increase is too much imho.

[protobuf] Open generic types Serialization/ Deserialization
Hi,
I have a Type :
CommandTData : Base where TData : ISomething.
TData are POCOs (DataContracts).
Im using ProtoBuf.net V2, and I'm registering the types to the Modal
on run time.
I'm having 2 issues:
1) on MetaType.Add(properties names) i get ObjectReference exception
when the Type includes Generic Type property.
Unhandled Exception: System.NullReferenceException: Object reference
not set to
an instance of an object.
at ProtoBuf.Meta.TypeModel.ResolveProxies(Type type) in C:\Dev
\protobuf-net\protobuf-net\Meta\TypeModel.cs:line 952
at ProtoBuf.Meta.RuntimeTypeModel.FindWithoutAdd(Type type) in C:
\Dev\protobuf-net\protobuf-net\Meta\RuntimeTypeModel.cs:line 118
at ProtoBuf.Meta.ValueMember..ctor(RuntimeTypeModel model, Type
parentType, Int32 fieldNumber, MemberInfo member, Type memberType,
Type itemType, Type defaul
tType, DataFormat dataFormat, Object defaultValue) in C:\Dev\protobuf-
net\protobuf-net\Meta\ValueMember.cs:line 75
at ProtoBuf.Meta.MetaType.AddField(Int32 fieldNumber, String
memberName, Type itemType, Type defaultType, Object defaultValue) in C:
\Dev\protobuf-net\protobu
f-net\Meta\MetaType.cs:line 1165
at ProtoBuf.Meta.MetaType.Add(String[] memberNames) in C:\Dev
\protobuf-net\protobuf-net\Meta\MetaType.cs:line 1046
2) If I'm skipping the Open generic types and im trying to register
them at serialization :
if (this._modal.CanSerializeContractType(objectType) == false)
{
this._modal.Add(objectType, false);
this._modal.CompileInPlace();
}
I get true in CanSerializeContractType, the type is serialized/
deserialized but only the base class (default values to all others).
What is the practice to do so without adding all permutations at
design time ?
Thanks,
Eyan.

Re: [protobuf] Error: Byte size calculation and serialization were inconsistent
This is weird. I don't see any clear potential cause, so I have a few questions: HTMud::EnvAdd item; item.set_id(ID); item.set_idtype(typeID); item.set_x(X); item.set_y(Y); item.set_z(Z); item.set_lockdown(lockdown); item.set_mapid(map); item.set_tilesetno(tilesetNo); item.set_tilesetx(tilesetX); item.set_regionx(regionX); item.set_regiony(regionZ); Are all these values primitives? Are any of them protocol buffers? Have you tried dumping the values that are being set when it dies, and trying a standalone program that sets the values and calls SerializeToString to see if it has the same problem? Have you made any changes to the protocol buffers library? I'm assuming you are using the released version of 2.4.1? Have you tried running this under valgrind? I'm wondering if there could be other weird memory corruption that is happening? That seems to be a frequent cause of this shouldn't be happening type errors, particularly things that appear/disappear occur with optimization enabled/disabled.

[protobuf] protobuf TextFormat question: Parsing TextFormat into message [fixed]
...previous message didn't have example code sanitized and probably
doesn't make sense. Please delete/ignore previous and use this one. :)
Hard to find much high-level documentation on using TextFormat, but
for some Python protobuf work I'm doing, the text format is much
easier to read (and easier to organize into test vector files) in the
protobuf text format, rather than manipulating the python objects
manually.
(I've changed message types/contents to generalize, please forgive any
typos, this isn't the real code)
my_envelope.proto (this file gets sent through protoc to generate
Python code):
message MyEnvelope {
optional InnerMessage innerMessage = 1;
}
and I have a test message that I'd like to take from TextFormat and
put into a protobuf message structure:
innerMessage {
value1: 100
value2: 200
}
I have found that I can get it to work in python using
from google.protobuf import text_format
import my_envelope_pb2
my_msg = my_envelope_pb2.MyEnvelope()
text_format.Merge(
innerMessage {
value1: 100
value2: 200
}
, my_msg)
But I guess my question is this- is there a preferred way to do this?
I had originally expected that ParseFromString would figure out that
this was an ASCII representation and call Merge appropriately.
i.e. I had expected the following would work
import my_envelope_pb2
my_msg = my_envelope_pb2.MyEnvelope()
my_msg.ParseFromString(
inner {
value1: 100
value2: 200
}
)
but from the errors it appeared that ParseFromString only deals with
string containers for binary format. Is this the case? Just trying to
make sure I'm not calling Merge at an innapropriate/strange layer when
some high-level call exists. As I mentioned, documentation on text
format is somewhat thin, so this is the best I could piece together
from API info. Thanks!
