Re: [protobuf] Re: Issue 269 in protobuf: Would like to have byte or int8 type for the message definition
The simple answer would be use the existing oversized types, and cast at the caller. Varint data in particular will either be 1 byte or 2 (50% each) for byte values. For longer sequences (rgba etc) there are existing fixed-32 and bytes. If the intent is to add a wire type to precisely represent a byte: that is hugely problematic. Adding a wire type is a significant thing, as: - the numbers of wire types is strictly limited, and there isn't much spare (unless the next wire type somehow means check the next byte for the longer wire type, or something) - all existing clients, libraries and deployments would need updating to even touch data with that wire type - it isn't even possible to ignore the data if you don't understand the wire type.

Re: [protobuf] Re: Issue 269 in protobuf: Would like to have byte or int8 type for the message definition
Int32 and such will see endianness issues when exchanging messages in-between cross-endian platforms hence only byte type suffices. On how we achieve fixed length string support once byte type is supported - Just create a message with specific number of byte elements and can name it like fixed8String instead. Accessors can be added via simple plugin that uses protoc insert point.

Re: [protobuf] Re: Issue 269 in protobuf: Would like to have byte or int8 type for the message definition
Really? AFAIK C++ strings handle null's just fine... they're
pascal-style strings, not c-style strings.
$ cat test.cc
#include string
#include iostream
int main() {
std::string a(a\0b, 3);
std::cout a.size() std::endl;
return 0;
}
$ g++ -o test test.cc
$ ./test
3
Or are you saying that the decoder is buggy and somehow doesn't
actually populate the string object correctly?

I think we'd want to have a pretty compelling use case before making a change of this size. For messages that have a handful of byte fields, using a standard int32 seems sufficient: there is some wasted space for the in-memory representation, but the encoding will be compact. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.
