Subject: [Rprotobuf-yada] Some help wanted
Message-ID: <73BF4AC06CB74F44BB2575D554395220076A098245@SRVEXMBV01.ga.local>

Hello,

                I'm using RProtobuf (on Debian Wheezy, R version 2.14.1 (2011-12-22), just downloaded RProtobuf).

I'm using this proto file:

message caudal{
        required uint32 id = 1;
        required string signo =2;
        optional string s_id =3;
}
message sector{
        required string nombre=1;
        required string nombre_abreviado=2;
        required string gerencia = 3;
        required uint32 activo=4;
        required string literal = 5;
        repeated caudal caudales = 6;
}
message explotacion{
        required string nombre =1;
        repeated sector sectores =2;
}

I'm putting data inside a proto from a data.frame that I read from CSV (by the way I suppose it's not the best option but nevertheless I try). But I'm not able to use correctly the add method (for adding a repeated message):

sectores <-new(explotacion,nombre="SB")
conjunto<-seq(1,length(gerencias[,1]))

for(i in conjunto){
                sectorini <-new(sector,
                               nombre=as.character(gerencias[i,]$NOM.SECTOR),
                               nombre_abreviado=as.character(gerencias[i,]$ABREVIAT),
                               gerencia = as.character(gerencias[i,]$GERENCIA),
                               activo = as.numeric(gerencias[i,]$codi),
                               literal = as.character(gerencias[i,]$LITERAL.FUNCI)
                                               )
                sectores$add("caudal",sectorini)
}

I get "Error in add(x, ...) : could not get FieldDescriptor for field"

Could you please help me to use that add function: "sectores$add("caudal",sectorini)"

Thank you


David

Subject: [Rprotobuf-yada] Also play with lists but I get the same problem
Message-ID: <73BF4AC06CB74F44BB2575D554395220076A098642@SRVEXMBV01.ga.local>

Hi,

                I also tried to do something more like the examples but I get the same error:


i=1
sectorini <-list(new(sector,
                               nombre=as.character(gerencias[i,]$NOM.SECTOR),
                               nombre_abreviado=as.character(gerencias[i,]$ABREVIAT),
                               gerencia = as.character(gerencias[i,]$GERENCIA),
                               activo = as.numeric(gerencias[i,]$codi),
                               literal = as.character(gerencias[i,]$LITERAL.FUNCI)
                                               ))

sectores$caudales<-sectorini


sectores$caudales<-sectorini
Error in `$<-`(`*tmp*`, "caudales", value = list(<S4 object of class "Message">)) :
  could not get FieldDescriptor for field

Is it my error or should I change the definition of the proto to carry the "caudal" message inside?

Regards

David Ibarra

I was using the same name for a protocol buffer message and the R object.

So if I use "zectores" rather then "sectores" it works, even using "add" rather than "list".

zectores <-new(explotacion,nombre="SB")
for(i in conjunto){
        zectores$add("sectores",new(sector,
                nombre=as.character(gerencias[i,]$NOM.SECTOR),
                nombre_abreviado=as.character(gerencias[i,]$ABREVIAT),
                gerencia = as.character(gerencias[i,]$GERENCIA),
                activo = as.numeric(gerencias[i,]$codi),
                literal = as.character(gerencias[i,]$LITERAL.FUNCI)
                )
        )
}

Also during test process, I changed the protocol definition, but I think It would work in the other case also:

message sector{
        message caudal{
        required uint32 id = 1;
        required string signo =2;
        optional string s_id =3;
        }

        required string nombre=1;
        required string nombre_abreviado=2;
        required string gerencia = 3;
        required uint32 activo=4;
        required string literal = 5;
        repeated caudal caudales = 6;
}
message explotacion{
        required string nombre =1;
        repeated sector sectores =2;
}

I have seen exactly this mistake many tines at Google. Probably we should
make it provide a more user friendly error when add on a descriptor is
called

Subject: [Rprotobuf-yada] How are multiple messages delimited?
Message-ID: <CD51419A.A96E%johansen@adobe.com>

Examples such as the one in http://lists.r-forge.r-project.org/pipermail/rprotobuf-yada/2009-November/000042.html indicate that RProtoBuf is able to read multiple messages from the same file. Is that correct? If so, how does RProtoBuf's read method expect those messages to be delimited? I have files with multiple messages delimited using the PB library's writeDelimitedTo(?) function but haven't been able to read it using RProtoBuf.
Any thoughts would be appreciated.

Are you using Python or Java's writeDelimitedTo function?  I think this
function isn't implemented in the C++ library that RProtoBuf is based on :


http://stackoverflow.com/questions/8269452/google-protocol-buffers-parsedelimitedfrom-and-writedelimitedto-for-c

Can you write a length before each method and write a helper function to
parse that?  It would be a nice addition to RProtoBuf.
