lua protobuf lua-intf proto3 google protocol buffer

luapbintf's Introduction

LuaPbIntf

Lua Protobuf interface.

Binding Protobuf to Lua with lua-intf, supporting lua53 and proto3.

LuaPbIntf is inspired by luapb, but has been rewritten to take advantage of lua-intf, which makes the binding easier to use and easier to understand.

LuaPbIntf will dynamic load Protocol Buffer message definition files .proto without code generation.

LuaPbIntf use lua table to present Message, encode() to encode lua message table to string, and decode() to decode string to lua message table.

Differ from luapb

Support proto3
Support service
Able to set the proto path
luapb skips some types such as: TYPE_SFIXED32. See issue.

Build

Build with conan

Install conan.
Add conan repositories
- conan remote add remote_bintray_bincrafters https://api.bintray.com/conan/bincrafters/public-conan
- conan remote add remote_bintray_jinq0123 https://api.bintray.com/conan/jinq0123/test
conan create . user/channel --build missing
- The result luapbintf.dll/luapbintf.so is in ~/.conan/data/luapbintf/0.1/user/channel/package/...
- Add build settings like: conan create user/channel --build missing -s arch=x86

Without conan (depricated)

Init third_party dir first, see third_party/README.md. Then use premake5 to generate VS2015 sln or Makefile to build. See premake/premake5.bat

On Windows, it is recommended by google that you use static protobuf only. On Linux, you may need to recompile libprotobuf.a with -fPIC, or link libprotobuf.so.

Link error

error LNK2019: unresolved external symbol "void __cdecl lua_settop(struct lua_State *,int)" (?lua_settop@@YAXPAUlua_State@@H@Z)

Please see issue #2.

By default, it expects the Lua library to build under C++. If you really want to use Lua library compiled under C, you can define LUAINTF_LINK_LUA_COMPILED_IN_CXX to 0.

Run test

See test/README.md

Example

Encode and Decode

local pb = require("luapbintf")

pb.import_proto_file("test.proto")

local msg = { uid = 12345 }
local sz = pb.encode("test.TestMsg", msg)

local msg2 = pb.decode("test.TestMsg", sz)
assert(msg2.uid == 12345)

Rpc

    assert(pb.get_rpc_input_name("test.Test", "Foo") == "test.TestMsg")
    assert(pb.get_rpc_output_name("test.Test", "Foo") == "test.CommonMsg")

Map field

local msgs = {}
msgs["k1"] = {}
msgs["k2"] = {}
pb.encode("test.TestMsg", { msgs = msgs })

Oneof field

    local msg = { msg2 = {} }
    local s = pb.encode("test.TestMsg", msg)
    local result = pb.decode("test.TestMsg", s)
    assert(result.name == "")
    assert(result.name2 == nil)
    assert(result.msg2)

Type Convertion

Number will be converted to string if necessary.

    local msg = { name = 12345 }
    local s = pb.encode("test.TestMsg", msg)
    assert(pb.decode("test.TestMsg", s).name == "12345")

Integer will be converted from one type to another. Such as from int64 4294967296 to int32 0:

    local msg = { n32 = 4294967296 + 123 }
    assert(msg.n32 == 4294967296 + 123)
    local s = pb.encode("test.TestMsg", msg)
    local msg2 = pb.decode("test.TestMsg", s)
    assert(msg2.n32 == 123)

String can be converted to integer or float:

    local msg = { d = "12345e-67" }
    local s = pb.encode("test.TestMsg", msg)
    assert(pb.decode("test.TestMsg", s).d == 12345e-67)

Can not convert float to integer.

> msg = { n32 = 1.1 }
> pb.encode("test.TestMsg", msg)
stdin:1: bad argument #-1 to 'encode' (number has no integer representation)

Enum is integer, but input string enum will be converted to integer.

    local msg = { cmd = "CMD_TYPE_CHECK" }
    local s = pb.encode("test.TestMsg", msg)
    assert(pb.decode("test.TestMsg", s).cmd == 2)

Repeated field is a lua array table and it is read from index 1 to len, ignoring others.

    local msg = { names = {"n1", "n2", "n3", [0] = "n1", [100] = "n100"} }
    local s = pb.encode("test.TestMsg", msg)
    local msg2 = pb.decode("test.TestMsg", s)
    assert(#msg2.names == 3)

Proto2 Extension

Proto2 extension is not supported, which is replaced by Any type in proto3.

您好，在lua协程中调用时出错了

您好，这个代码编译好so动态库，普通测试可以，但是在lua的协程中调用时，encode和decode就不生效了，请问造成这个的原因有哪些呢，测试了好久不知道原因，希望能够解答一下。

声明的时候报错是什么情况？

package.cpath = "../luaclib/?.so;"
local pb=require("luapbintf")
报下面的错误。是不是我还少包含了什么？

解码的过程碰到一个奇怪的问题

协议体
syntax = "proto3";
package login;
message login {
string account = 1 ;
string password = 2 ;
int32 sdkid = 3 ;
}

发送下面这个包，客户端发完后直接解包是正常解出来的

send pbstr:0A 04 6B 69 6E 67 12 06 31 31 31 31 31 31 18 01
send:cmd(login.login) check(0) len(24) msg->{
["password"] = "111111",
["account"] = "king",
["sdkid"] = 1,
}

服务端接收到这个包的打印
recv pbstr:0A 04 6B 69 6E 67 12 06 31 31 31 31 31 31 18 01
recv:cmd(login.login) check(0) msg->"
king111111"

这个msg里面直接是个字符串了。
我看了下。
local msg = pb.decode(cmd, pbstr)
这里msg解码后得到的是一个字符串。
解码失败会直接得到tostring的结果吗？使用的协议文件是同一个。怎么会解码失败呢

调用luapbintf.import_proto_file报编码问题

luapbintf.import_proto_file 调用这个接口时报下面的错误

协议文件
显示行号是string password = 2; 这一句的错误

Can you support 5.1 version of lua?

It describes Binding Protobuf 3 to Lua 5.3

在build过程中遇到麻烦

有2个问题：
1.build过程中报错：
，需要的xxx.h文件都已经拷贝到对应的目录里了。不知道是不是环境问题，如果是环境问题，请告知改如何配置环境；
2.在thrid_party里的readme.md里有说要拷贝lib目录到该目录里，请问这个lib是从哪里来的呢？谢谢。

Can't resolve this format of proto3

message A
{
repeated uint64 img_pos =1 [packed=true];
}

message AAA
{
repeated enum_win_type enType =1 [packed=true]; //
repeated A win_pos = 2 ; //
}

I want to decode AAA message from our server send data.
I can use c++ decode it, but lubpbint can't.
Do you have any time to resolve this?

Only need to decode it, do not need encode it.

您好，为什么Makefile中没有连接lua的库呢？

您好，为什么Makefile中没有连接lua的库呢？
编译后生成的luapbIntf.so，用ldd -r查看显示很多undefined symbols,
是不是我哪一步错了，那些库都和源码都添加到对应的目录下了

build succes,but use fail

luapbintf.so: undefined symbol: _Z14lua_pushstringP9lua_StatePKc

上一个问题是怀疑有冲突问题。现在确认了是在协程下的绑定有问题

上次是在skynet中测试。发现在skynet.start中无法正常解码
然后经过一段时间的观察。并且问了skynet的作者。结论是你这边在协程中的绑定lua时的问题。
测试代码如下

pb.import_proto_file("login.proto")
local pbstr = pb.encode("login.login", {account="king",password="111111"})
print("encode")
local pbmsg=pb.decode("login.login",pbstr)
print(tool.dump(pbmsg))
print("=========================")
local cor=coroutine.create(function()
local msg= pb.decode("login.login", pbstr)
print("decode")
print(tool.dump(msg))
end)
coroutine.resume(cor)

打印结果如下
encode
{
["password"] = "111111",
["sdkid"] = 0,
["account"] = "king",
}

decode
"
king111111"

After build required lib, including lua and protobuf, but run the sln LuaPbIntf occured link error .

maybe there is something wrong with my procedure of building the lua lib.

Really appreciate your help
.

看不懂conan的操作步骤的留个爪。。是不是只有我没看懂

how to build to .so not .dylib

how to build to .so not .dylib on macOS
.dylib. can't read

无法编译编译时遇到问题

本人在 ubuntu 和 windows10 下都遇到无法编译
按照这个：
Build with conan
Install conan.
Add conan repositories
conan remote add remote_bintray_bincrafters https://api.bintray.com/conan/bincrafters/public-conan
conan remote add remote_bintray_jinq0123 https://api.bintray.com/conan/jinq0123/test
conan create . user/channel --build missing
The result luapbintf.dll/luapbintf.so is in ~/.conan/data/luapbintf/0.1/user/channel/package/...
Add build settings like: conan create user/channel --build missing -s arch=x86

步骤到最后 conan create git下载的py文件 --build missing 会到一步输入到用户名和密码的地步卡到无法进行下一步编译。
望大佬给个解决方案

luajit support

would be great if we could use this library from luajit

uint64 support broken

given the following protobuf definition:

message MyMsg {
  uint64 uint64f = 1;
  int64  int64f  = 2;
}

and the following code:

   local msg = {
      uint64f = math.pow(2,32)
      int64f = math.pow(2,32)
   }
   local x =pb.decode("MyMsg", pb.encode( "MyMsg", msg ))
   print ( msg.int64f, msg.uint64f )
   print ( x.int64f, x.uint64f )

shows the following:

4294967296	4294967296
4294967296	0

Note that the int64 field is handled correctly, but uint64 is not.
Using a value 2^32 causes the issue; 2^32-1 works as expected.
